Simulated reality
–
Simulated reality is the hypothesis that reality could be simulated—for example by computer simulation—to a degree indistinguishable from true reality. It could contain conscious minds which may or may not be aware that they are living inside a simulation. This is quite different from the current, technologically achievable concept of virtual reality, virtual reality is easily distinguished from the experience of actuality, participants are never in doubt about the nature of what they experience. Simulated reality, by contrast, would be hard or impossible to separate from true reality, there has been much debate over this topic, ranging from philosophical discourse to practical applications in computing. The simulation hypothesis was first published by Hans Moravec, later, the philosopher Nick Bostrom developed an expanded argument examining the probability of our reality being a simulation. His argument states that at least one of the statements is very likely to be true,1. Human civilization is unlikely to reach a level of technological maturity capable of producing simulated realities, any entities with our general set of experiences are almost certainly living in a simulation. In greater detail, Bostrom is attempting to prove a tripartite disjunction, epistemologically, it is not impossible to tell whether we are living in a simulation. For example, Bostrom suggests that a window could pop up saying, nonetheless, should any evidence come to light, either for or against the skeptical hypothesis, it would radically alter the aforementioned probability. Computationalism is a philosophy of mind theory stating that cognition is a form of computation and it is relevant to the Simulation hypothesis in that it illustrates how a simulation could contain conscious subjects, as required by a virtual people simulation. For example, it is known that physical systems can be simulated to some degree of accuracy. If computationalism is correct, and if there is no problem in generating artificial consciousness or cognition, however, the relationship between cognition and phenomenal qualia of consciousness is disputed. It is possible that consciousness requires a vital substrate that a computer cannot provide, and this would undermine Nick Bostroms simulation argument, we cannot be a simulated consciousness, if consciousness, as we know it, cannot be simulated. However, the hypothesis remains intact, we could still be envatted brains, existing as conscious beings within a simulated environment. This argument states that a Platonic realm or ultimate ensemble would contain every algorithm, Hans Moravec has explored the simulation hypothesis and has argued for a kind of mathematical Platonism according to which every object can be regarded as implementing every possible computation. A dream could be considered a type of simulation capable of fooling someone who is asleep, as a result, the dream hypothesis cannot be ruled out, although it has been argued that common sense and considerations of simplicity rule against it. One of the first philosophers to question the distinction between reality and dreams was Zhuangzi, a Chinese philosopher from the 4th century BC and he didnt know he was Zhuangzi. Suddenly he woke up and there he was, solid and unmistakable Zhuangzi, but he didnt know if he was Zhuangzi who had dreamt he was a butterfly, or a butterfly dreaming he was Zhuangzi

European Space Agency

The European Space Agency is an intergovernmental organisation of 22 member states, dedicated to the exploration of space. Established in 1975 and headquartered in Paris, France, ESA has a staff of about 2,000. The main European launch vehicle Ariane 5 is operated through Arianespace with ESA sharing in the costs of launching, after World War II, many European scientists left Western Europe in order to work with the United States. The meeting was attended by representatives from eight countries, including Harrie Massey. The Western European nations decided to have two different agencies, one concerned with developing a system, ELDO, and the precursor of the European Space Agency. The latter was established on 20 March 1964 by an agreement signed on 14 June 1962, from 1968 to 1972, ESRO launched seven research satellites. ESA in its current form was founded with the ESA Convention in 1975, ESA has 10 founding member states, Belgium, Denmark, France, Germany, Italy, the Netherlands, Spain, Sweden, Switzerland and the United Kingdom. These signed the ESA Convention in 1975 and deposited the instruments of ratification by 1980, during this interval the agency functioned in a de facto fashion. ESA launched its first major scientific mission in 1975, Cos-B, ESA joined NASA in the IUE, the worlds first high-orbit telescope, which was launched in 1978 and operated very successfully for 18 years. A number of successful Earth-orbit projects followed, and in 1986 ESA began Giotto, its first deep-space mission, to study the comets Halley and Grigg–Skjellerup. Hipparcos, a mission, was launched in 1989 and in the 1990s SOHO, Ulysses. Recent scientific missions in co-operation with NASA include the Cassini–Huygens space probe, as the successor of ELDO, ESA has also constructed rockets for scientific and commercial payloads. Ariane 1, launched in 1979, brought mostly commercial payloads into orbit from 1984 onward, the successor launch vehicle of Ariane 5, the Ariane 6 is already in the definition stage and is envisioned to enter service in the 2020s. The beginning of the new millennium saw ESA become, along with agencies like NASA, JAXA, ISRO, CSA and Roscosmos, one of the major participants in scientific space research. Although ESA had relied on co-operation with NASA in previous decades, especially the 1990s, changed circumstances led to decisions to rely more on itself, a 2011 press issue thus stated, Russia is ESAs first partner in its efforts to ensure long-term access to space. ESA maintains its scientific and research projects mainly for astronomy-space missions such as Corot, launched on 27 December 2006 and this is the reason space exploration is an integral part of overall space activities. It has always been so, and it will be more important in the future. ESA describes its work in two overlapping ways, For the general public the various fields of work are described as Activities, Member states participate to varying degrees in the mandatory and optional space programmes

Darmstadt is a city in the state of Hesse in Germany, located in the southern part of the Rhine-Main-Area. Darmstadt has a population around 150,000, the Darmstadt Larger Urban Zone has 430,993 inhabitants. Darmstadt holds the official title City of Science as it is a centre of scientific institutions, universities. The existence of the elements were also confirmed at GSI Centre for Heavy Ion Research, nihonium, flerovium, moscovium, livermorium. Darmstadt is also the seat of the worlds oldest pharmaceutical company, Merck, Darmstadt was formerly the capital of a sovereign country, the Grand Duchy of Hesse and its successor, the Peoples State of Hesse, a federal state of Germany. As the capital of an increasingly prosperous duchy, the city gained some international prominence, in the 20th century, industry, as well as large science and electronics sectors became increasingly important, and are still a major part of the citys economy. It is also home to the football club SV Darmstadt 98, Darmstadt, Indiana was named after Darmstadt and for the former Royal Family. The name Darmstadt first appears towards the end of the 11th century, the origins of the name are unknown. Dar-mund in Middle Low German is translated as Boggy Headlands, even locals often believe, incorrectly, that the name derives from the Darmbach. In fact, the received its current name much later, after the city. Darmstadt was chartered as a city by the Holy Roman Emperor Ludwig the Bavarian in 1330, the city, then called Darmstait, became a secondary residence for the counts, with a small castle established at the site of the current, much larger edifice. When the house of Katzenelnbogen became extinct in 1479, the city was passed to the Landgraviate of Hesse, the city grew in population during the 19th century from little over 10,000 to 72,000 inhabitants. A polytechnical school, which became a Technical University now known as TU Darmstadt, was established in 1877. In the beginning of the 20th century, Darmstadt was an important centre for the art movement of Jugendstil, annual architectural competitions led to the building of many architectural treasures of this period. Also during this period, in 1912 the chemist Anton Kollisch, working for the pharmaceutical company Merck, Darmstadts municipal area was extended in 1937 to include the neighbouring localities of Arheilgen and Eberstadt, and in 1938 the city was separated administratively from the surrounding district. Darmstadt was the first city in Germany to force Jewish shops to close in early 1933, the shops were only closed for one day, for endangering communal order and tranquility. In 1942, over 3,000 Jews from Darmstadt were first forced into a camp located in the Liebigschule. Darmstadt was first bombed on 30 July 1940, and 34 other air raids would follow before the wars end, the old city centre was largely destroyed in a British bombing raid on 11 September 1944

Rover (space exploration)
–
A rover is a space exploration vehicle designed to move across the surface of a planet or other celestial body. Some rovers have been designed to transport members of a human spaceflight crew, Rovers usually arrive at the planetary surface on a lander-style spacecraft. Rovers are created to land on another planet, besides Earth, to find out information and they can collect dust, rocks, and even take pictures. Rovers have several advantages over stationary landers, they examine more territory, if they are solar powered, they can place themselves in sunny positions to weather winter months. They can also advance the knowledge of how to perform very remote robotic vehicle control which is necessarily semi-autonomous due to the speed of light. Their advantages over orbiting spacecraft are that they can make observations to a microscopic level, Rovers arrive on spacecraft and are used in conditions very distinct from those on the Earth, which makes some demands on their design. Rovers have to high levels of acceleration, high and low temperatures, pressure, dust, corrosion, cosmic rays. Rovers are usually packed for placing in a spacecraft, because it has limited capacity and they are also attached to a spacecraft, so devices for removing these connections are installed. For example, sending a signal from Mars to Earth takes between 3 and 21 minutes, giving a rover some rudimentary visual identification capabilities to make simple distinctions can allow engineers to speed up the reconnaissance. Other rover designs that do not use wheeled approaches are possible, mechanisms that utilize walking on robotic legs, hopping, rolling, etc. are possible. The Soviet rover was intended to be the first roving remote-controlled robot on the Moon, the Lunokhod 1 rover landed on the Moon in November 1970. It was the first roving remote-controlled robot to land on any celestial body, the Soviet Union launched Lunokhod 1 aboard the Luna 17 spacecraft on November 10,1970, and it entered lunar orbit on November 15. The spacecraft soft-landed in the Sea of Rains region on November 17, the lander had dual ramps from which Lunokhod 1 could descend to the lunar surface, which it did at 06,28 UT. From November 17,1970 to November 22,1970 the rover drove 197 m and it also analyzed the lunar soil. The last successful communications session with Lunokhod 1 was on September 14,1971, having worked for 11 months, Lunokhod 1 held the durability record for space rovers for more than 30 years, until a new record was set by the Mars Exploration Rovers. NASA included Lunar Roving Vehicles in three Apollo missions, Apollo 15, Apollo 16 and Apollo 17, the Lunokhod 2 was the second of two unmanned lunar rovers landed on the Moon by the Soviet Union as part of the Lunokhod program. The rover became operational on the Moon on January 16,1973 and it was the second roving remote-controlled robot to land on any celestial body. The Soviet Union launched Lunokhod 2 aboard the Luna 21 spacecraft on January 8,1973, the spacecraft soft-landed in the eastern edge of the Mare Serenitatis region on January 15,1973

Satellites
–
In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit. Such objects are called artificial satellites to distinguish them from natural satellites such as Earths Moon. In 1957 the Soviet Union launched the worlds first artificial satellite, since then, about 6,600 satellites from more than 40 countries have been launched. According to a 2013 estimate,3,600 remained in orbit, of those, about 1,000 were operational, the rest have lived out their useful lives and become space debris. Approximately 500 operational satellites are in orbit,50 are in medium-Earth orbit. A few large satellites have been launched in parts and assembled in orbit. Over a dozen space probes have been placed into orbit around other bodies and become artificial satellites to the Moon, Mercury, Venus, Mars, Jupiter, Saturn, a few asteroids, Satellites are used for many purposes. Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, Space stations and human spacecraft in orbit are also satellites. Satellite orbits vary greatly, depending on the purpose of the satellite, well-known classes include low Earth orbit, polar orbit, and geostationary orbit. A launch vehicle is a rocket that throws a satellite into orbit, usually it lifts off from a launch pad on land. Some are launched at sea from a submarine or a mobile maritime platform, Satellites are usually semi-independent computer-controlled systems. Satellite subsystems attend many tasks, such as power generation, thermal control, telemetry, attitude control, the first fictional depiction of a satellite being launched into orbit was a short story by Edward Everett Hale, The Brick Moon. The idea surfaced again in Jules Vernes The Begums Fortune, in 1903, Konstantin Tsiolkovsky published Exploring Space Using Jet Propulsion Devices, which is the first academic treatise on the use of rocketry to launch spacecraft. He calculated the speed required for a minimal orbit. In 1928, Herman Potočnik published his book, The Problem of Space Travel — The Rocket Motor. He described the use of orbiting spacecraft for observation of the ground, in a 1945 Wireless World article, the English science fiction writer Arthur C. Clarke described in detail the possible use of communications satellites for mass communications. He suggested that three geostationary satellites would provide coverage over the entire planet, the first artificial satellite was Sputnik 1, launched by the Soviet Union on October 4,1957, and initiating the Soviet Sputnik program, with Sergei Korolev as chief designer. This in turn triggered the Space Race between the Soviet Union and the United States, Sputnik 1 helped to identify the density of high atmospheric layers through measurement of its orbital change and provided data on radio-signal distribution in the ionosphere

A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow a sequence of operations, called a program, such computers are used as control systems for a very wide variety of industrial and consumer devices. The Internet is run on computers and it millions of other computers. Since ancient times, simple manual devices like the abacus aided people in doing calculations, early in the Industrial Revolution, some mechanical devices were built to automate long tedious tasks, such as guiding patterns for looms. More sophisticated electrical machines did specialized analog calculations in the early 20th century, the first digital electronic calculating machines were developed during World War II. The speed, power, and versatility of computers has increased continuously and dramatically since then, conventionally, a modern computer consists of at least one processing element, typically a central processing unit, and some form of memory. The processing element carries out arithmetic and logical operations, and a sequencing, peripheral devices include input devices, output devices, and input/output devices that perform both functions. Peripheral devices allow information to be retrieved from an external source and this usage of the term referred to a person who carried out calculations or computations. The word continued with the same meaning until the middle of the 20th century, from the end of the 19th century the word began to take on its more familiar meaning, a machine that carries out computations. The Online Etymology Dictionary gives the first attested use of computer in the 1640s, one who calculates, the Online Etymology Dictionary states that the use of the term to mean calculating machine is from 1897. The Online Etymology Dictionary indicates that the use of the term. 1945 under this name, theoretical from 1937, as Turing machine, devices have been used to aid computation for thousands of years, mostly using one-to-one correspondence with fingers. The earliest counting device was probably a form of tally stick, later record keeping aids throughout the Fertile Crescent included calculi which represented counts of items, probably livestock or grains, sealed in hollow unbaked clay containers. The use of counting rods is one example, the abacus was initially used for arithmetic tasks. The Roman abacus was developed from used in Babylonia as early as 2400 BC. Since then, many forms of reckoning boards or tables have been invented. In a medieval European counting house, a checkered cloth would be placed on a table, the Antikythera mechanism is believed to be the earliest mechanical analog computer, according to Derek J. de Solla Price. It was designed to calculate astronomical positions and it was discovered in 1901 in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, and has been dated to circa 100 BC

Game controller

A game controller is a device used with games or entertainment systems to provide input to a video game, typically to control an object or character in the game. A controller is connected to a game console or computer by means of a wire or cord, although, since the mid-2000s. Input devices that have been classified as game controllers include keyboards, mouses, gamepads, joysticks, special purpose devices, such as steering wheels for driving games and light guns for shooting games, are also game controllers. Game controllers have been designed and improved over the years to be as user friendly as possible, the Microsoft Xbox controller, with its shoulder triggers that mimic actual triggers such as those found on guns, has become popular for shooting games. Some controllers are designed to be deliberately best for one type of game, such as steering wheels for driving games, One of the first video game controllers was a simple dial and single button, used to control the game Tennis for Two. Controllers have since evolved to include directional pads, multiple buttons, analog sticks, joysticks, motion detection, touch screens, a gamepad, also known as a joypad, is held in both hands with thumbs and fingers used to provide input. Gamepads can have a number of action buttons combined with one or more omnidirectional control sticks or buttons, action buttons are generally handled with the digits on the right hand, and the directional input handled with the left. Gamepads are the means of input on most modern video game consoles. Most modern game controllers are a variation of a standard gamepad, common additions include shoulder buttons placed along the edges of the pad, centrally placed buttons labeled start, select, and mode, and an internal motor to provide haptic feedback. As modern game controllers advance, so to does their user ability qualities, typically, the controllers become smaller and more compact as to more easily, and comfortably, fit within the users hand. Modern examples can be drawn from such as Xbox, whose controller has transformed subtly, yet dramatically. A paddle is a controller that features a wheel and one or more fire buttons. The wheel is used to control movement of the player or of an object along one axis of the video screen. Paddle controllers were the first analog controllers and they lost popularity when paddle, a variation, the Atari driving controller, appeared on the Atari 2600. Designed specifically for the game Indy 500, it functioned almost identically in operation, the exceptions were that its wheel can be continuously rotated in either direction, and it was missing the extra paddle included on the previous model. Unlike a spinner, friction prevented the wheel from gaining momentum, a joystick is a peripheral that consists of a handheld stick that can be tilted around either of two axes and twisted around a third. The joystick is used for flight simulators. HOTAS controllers, composed of a joystick and throttle quadrant are a combination for flight simulation among its most fanatic devotees

Haptic technology
–
Haptic or kinesthetic communication recreates the sense of touch by applying forces, vibrations, or motions to the user. Haptic devices may incorporate tactile sensors that measure forces exerted by the user on the interface, most researchers distinguish three sensory systems related to sense of touch in humans, cutaneous, kinesthetic and haptic. All perceptions mediated by cutaneous and/or kinesthetic sensibility are referred to as tactual perception, the sense of touch may be classified as passive and active, and the term haptic is often associated with active touch to communicate or recognize objects. Haptic technology has made it possible to investigate how the sense of touch works by allowing the creation of carefully controlled haptic virtual objects. The word haptic, from the Greek, ἁπτικός, means pertaining to the sense of touch and comes from the Greek verb ἅπτεσθαι haptesthai, One of the earliest applications of haptic technology was in large aircraft that use servomechanism systems to operate control surfaces. Such systems tend to be one-way, meaning external forces applied aerodynamically to the surfaces are not perceived at the controls. Here, the normal forces are simulated with springs and weights. In lighter aircraft without servo systems, as the aircraft approached a stall the aerodynamic buffeting was felt in the pilots controls and this was a useful warning of a dangerous flight condition. This control shake is not felt when servo control systems are used, alternatively, the servo force may be measured and the signal directed to a servo system on the control, known as force feedback. Force feedback has been implemented experimentally in some excavators and is useful when excavating mixed material such as large rocks embedded in silt or clay and it allows the operator to feel and work around unseen obstacles, enabling significant increases in productivity and less risk of damage to the machine. The first US patent for a telephone was granted to Thomas D. Shannon in 1973. An early tactile man-machine communication system was constructed by A. Michael Noll at Bell Telephone Laboratories, Inc. in the early 1970s, the Interactor Vest is worn over the upper torso and the audio signal is reproduced through a speaker embedded in the vest. Both the Vest and the Cushion were launched with a tag of $99. In 1995 Norwegian Geir Jensen described a wrist watch haptic device with a skin tap mechanism and it would connect to a mobile phone via Bluetooth. Tapping-frequency patterns would identify callers to a mobile and enable the wearer to respond by selected short messages and it was submitted for a governmental innovation contest and received no award. It was not pursued or published until recovered in 2015, the Tap-in device by Jensen was devised facing the user to avoid twisting of the wrist, see image. It would adapt across all mobile phone and watch brands, in 2015 Apple started to sell a wrist watch which included skin tap sensing of notifications and alerts to mobile phone of the watch wearer.

Video gaming

A video game is an electronic game that involves interaction with a user interface to generate visual feedback on a video device such as a TV screen or computer monitor. The word video in video game referred to a raster display device. Some theorists categorize video games as an art form, but this designation is controversial, the electronic systems used to play video games are known as platforms, examples of these are personal computers and video game consoles. These platforms range from large mainframe computers to small handheld computing devices, the input device used for games, the game controller, varies across platforms. Common controllers include gamepads, joysticks, mouse devices, keyboards, the touchscreens of mobile devices, and buttons, or even, with the Kinect sensor, a persons hands and body. Players typically view the game on a screen or television or computer monitor, or sometimes on virtual reality head-mounted display goggles. There are often game sound effects, music and, in the 2010s, some games in the 2000s include haptic, vibration-creating effects, force feedback peripherals and virtual reality headsets. In the 2010s, the game industry is of increasing commercial importance, with growth driven particularly by the emerging Asian markets and mobile games. As of 2015, video games generated sales of USD74 billion annually worldwide, early games used interactive electronic devices with various display formats. The earliest example is from 1947—a Cathode ray tube Amusement Device was filed for a patent on 25 January 1947, by Thomas T. Goldsmith Jr. and Estle Ray Mann, and issued on 14 December 1948, as U. S. Written by MIT students Martin Graetz, Steve Russell, and Wayne Wiitanens on a DEC PDP-1 computer in 1961, and the hit ping pong-style Pong, used the DEC PDP-1s vector display to have two spaceships battle each other. In 1971, Computer Space, created by Nolan Bushnell and Ted Dabney, was the first commercially sold and it used a black-and-white television for its display, and the computer system was made of 74 series TTL chips. The game was featured in the 1973 science fiction film Soylent Green, Computer Space was followed in 1972 by the Magnavox Odyssey, the first home console. Modeled after a late 1960s prototype console developed by Ralph H. Baer called the Brown Box and these were followed by two versions of Ataris Pong, an arcade version in 1972 and a home version in 1975 that dramatically increased video game popularity. The commercial success of Pong led numerous other companies to develop Pong clones and their own systems, the game inspired arcade machines to become prevalent in mainstream locations such as shopping malls, traditional storefronts, restaurants, and convenience stores. The game also became the subject of articles and stories on television and in newspapers and magazines. Space Invaders was soon licensed for the Atari VCS, becoming the first killer app, the term platform refers to the specific combination of electronic components or computer hardware which, in conjunction with software, allows a video game to operate. The term system is commonly used

Telepresence
–
Telepresence requires that the users senses be provided with such stimuli as to give the feeling of being in that other location. Additionally, users may be given the ability to affect the remote location, in this case, the users position, movements, actions, voice, etc. may be sensed, transmitted and duplicated in the remote location to bring about this effect. Therefore information may be traveling in both directions between the user and the remote location, a popular application is found in telepresence videoconferencing, the highest possible level of videotelephony. Telepresence via video deploys greater technical sophistication and improved fidelity of both sight and sound than in traditional videoconferencing, in his science fiction short story Waldo, Heinlein first proposed a primitive telepresence master-slave manipulator system. The Brother Assassin, written by Fred Saberhagen in 1969, introduced the concept for a telepresence master-slave humanoid system. As the control of its movements passed over to him, the slave started gradually to lean to one side, tilting back his head, he could look up through the slaves eyes to see the master-unit, with himself inside, maintaining the same attitude on its complex suspension. The first commercially successful telepresence company, Teleport, was founded in 1993 by David Allen, before TeleSuite, they ran a resort business from which the original concept emerged, because they often found businesspeople would have to cut their stays short to participate in important meetings. Their idea was to develop a technology that would allow businesspeople to attend their meetings without leaving the resorts so that they could lengthen their hotel stays, Hilton Hotels had originally licensed to install them in their hotels throughout the United States and other countries, but use was low. The idea lost momentum, with Hilton eventually backing out, TeleSuite later began to focus less on the hospitality industry and more on business-oriented telepresence systems. Shareholders eventually held enough stock to replace the original leadership. David Allen purchased all of the assets of TeleSuite and appointed Scott Allen as president of the new company called Destiny Conferencing. Destiny Conferencing licensed its patent portfolio to HP which became the first large company to join the telepresence industry, soon followed by such as Cisco. After forming an agreement with Pleasanton-based Polycom, Destiny Conferencing sold on January 5,2007 to Polycom for $60 million. An important research project in telepresence began in 1990, located at the University of Toronto, the Ontario Telepresence Project was an interdisciplinary effort involving social sciences and engineering. Its final report stated that it. was a three year, $4, the OTP, which ended in December 1994, was part of the International Telepresence Project which linked Ontario researchers to their counterparts in four European nations. The Project’s major sponsor was the Province of Ontario, through two of its Centres of Excellence—the Information Technology Research Centre and the Telecommunications Research Institute of Ontario. An industry expert described some benefits of telepresence, There were four drivers for our decision to do more business over video and we wanted to reduce our travel spend, reduce our carbon footprint and environmental impact, improve our employees work/life balance, and improve employee productivity. Rather than traveling great distances in order to have a meeting, it is now commonplace to instead use a telepresence system

Augmented reality

Augmented reality is a live direct or indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data. It is related to a general concept called mediated reality. As a result, the functions by enhancing one’s current perception of reality. By contrast, virtual reality replaces the real world with a simulated one, augmentation is conventionally in real time and in semantic context with environmental elements, such as sports scores on TV during a match. With the help of advanced AR technology the information about the real world of the user becomes interactive. Information about the environment and its objects is overlaid on the real world and this information can be virtual or real, e. g. seeing other real sensed or measured information such as electromagnetic radio waves overlaid in exact alignment with where they actually are in space. Augmented reality brings out the components of the world into a persons perceived real world. One example is an AR Helmet for construction workers which displays information about the construction sites, hardware components for augmented reality are, processor, display, sensors and input devices. Various technologies are used in Augmented Reality rendering including optical projection systems, monitors, hand held devices, a head-mounted display is a display device paired to the forehead such as a harness or helmet. HMDs place images of both the world and virtual objects over the users field of view. Modern HMDs often employ sensors for six degrees of freedom monitoring that allow the system to align virtual information to the physical world, HMDs can provide VR users mobile and collaborative experiences. Specific providers, such as uSens and Gestigon, are even including gesture controls for full virtual immersion, in January 2015, Meta launched a project led by Horizons Ventures, Tim Draper, Alexis Ohanian, BOE Optoelectronics and Garry Tan. On February 17,2016, Meta announced their product at TED. AR displays can be rendered on devices resembling eyeglasses, a head-up display, also known as a HUD, is a transparent display that presents data without requiring users to look away from their usual viewpoints. Near eye augmented reality devices can be used as portable head-up displays as they can show data, information, many definitions of augmented reality only define it as overlaying the information. CrowdOptic technology can be used by Google Glass users to learn where to look at a point in time. In January 2015, Microsoft introduced HoloLens, which is an independent smartglasses unit, First impressions and opinions have been generally that HoloLens is a superior device to the Google Glass, and manages to do several things right in which Glass failed. Contact lenses that display AR imaging are in development and these bionic contact lenses might contain the elements for display embedded into the lens including integrated circuitry, LEDs and an antenna for wireless communication

A smartphone is a mobile phone with an advanced mobile operating system that combines features of a personal computer operating system with other features useful for mobile or handheld use. Smartphones can access the Internet and can run a variety of third-party software components and they typically have a color display with a graphical user interface that covers more than 76% of the front surface. In 1999, the Japanese firm NTT DoCoMo released the first smartphones to achieve mass adoption within a country, smartphones became widespread in the late 2000s. Most of those produced from 2012 onward have high-speed mobile broadband 4G LTE, motion sensors, in the third quarter of 2012, one billion smartphones were in use worldwide. Global smartphone sales surpassed the sales figures for regular cell phones in early 2013, devices that combined telephony and computing were first conceptualized by Nikola Tesla in 1909 and Theodore Paraskevakos in 1971 and patented in 1974, and were offered for sale beginning in 1993. Paraskevakos was the first to introduce the concepts of intelligence, data processing and they were installed at Peoples Telephone Company in Leesburg, Alabama and were demonstrated to several telephone companies. The original and historic working models are still in the possession of Paraskevakos, the first mobile phone to incorporate PDA features was a prototype developed by Frank Canova in 1992 while at IBM and demonstrated that year at the COMDEX computer industry trade show. It included PDA features and other mobile applications such as maps, stock reports. A refined version was marketed to consumers in 1994 by BellSouth under the name Simon Personal Communicator, the Simon was the first commercially available device that could be properly referred to as a smartphone, although it was not called that in 1994. The term smart phone appeared in print as early as 1995, in the mid-late 1990s, many mobile phone users carried a separate dedicated PDA device, running early versions of operating systems such as Palm OS, BlackBerry OS or Windows CE/Pocket PC. These operating systems would later evolve into mobile operating systems, in March 1996, Hewlett-Packard released the OmniGo 700LX, a modified HP 200LX palmtop PC that supported a Nokia 2110 phone with ROM-based software to support it. It had a 640×200 resolution CGA compatible four-shade gray-scale LCD screen and could be used to place and receive calls and it was also 100% DOS5.0 compatible, allowing it to run thousands of existing software titles, including early versions of Windows. In August 1996, Nokia released the Nokia 9000 Communicator, a cellular phone based on the Nokia 2110 with an integrated PDA based on the PEN/GEOS3.0 operating system from Geoworks. The two components were attached by a hinge in what known as a clamshell design, with the display above. The PDA provided e-mail, calendar, address book, calculator and notebook applications, text-based Web browsing, when closed, the device could be used as a digital cellular phone. In June 1999 Qualcomm released the pdQ Smartphone, a CDMA digital PCS Smartphone with an integrated Palm PDA, subsequent landmark devices included, The Ericsson R380 by Ericsson Mobile Communications. The first device marketed as a smartphone, it combined the functions of a phone and PDA. The Kyocera 6035 introduced by Palm, Inc, combining a PDA with a mobile phone, it operated on the Verizon network, and supported limited Web browsing

Immersion (virtual reality)
–
Immersion into virtual reality is a perception of being physically present in a non-physical world. The perception is created by surrounding the user of the VR system in images, the name is a metaphoric use of the experience of submersion applied to representation, fiction or simulation. The degree to which the virtual or artistic environment faithfully reproduces reality determines the degree of suspension of disbelief, the greater the suspension of disbelief, the greater the degree of presence achieved. According to Ernest W. Players feel in the zone while perfecting actions that result in success, Strategic immersion Strategic immersion is more cerebral, and is associated with mental challenge. Chess players experience strategic immersion when choosing a correct solution among an array of possibilities. Narrative immersion Narrative immersion occurs when players become invested in a story, in addition to these, they add a new category, Spatial immersion Spatial immersion occurs when a player feels the simulated world is perceptually convincing. The player feels that he or she is there and that a simulated world looks. It is defined as a subjective sensation of being there in a scene depicted by a medium. Most designers focus on the used to create a high-fidelity virtual environment, however. It is the perception, although generated by and/or filtered through human-made technology. Virtual reality glasses can produce a feeling of being in a simulated world. According to Oculus VR, the requirements to achieve this visceral reaction are low-latency. Michael Abrash gave a talk on VR at Steam Dev Days in 2014 and it consists of immersion in an artificial environment where the user feels just as immersed as they usually feel in consensus reality. The most considered method would be to induce the sensations that made up the reality in the nervous system directly. In functionalism/conventional biology we interact with consensus reality through the nervous system, thus we receive all input from all the senses as nerve impulses. It gives your neurons a feeling of heightened sensation and it would involve the user receiving inputs as artificially stimulated nerve impulses, the system would receive the CNS outputs and process them allowing the user to interact with the virtual reality. Natural impulses between the body and central nervous system would need to be prevented, a feedback system between the user and the computer which stores the information would also be needed. Considering how much information would be required for such a system and this will allow the correct sensations in the user, and actions in the virtual reality to occur

Antonin Artaud
–
Antoine Artaud was born 4 September 1896 in Marseille, France, to Euphrasie Nalpas and Antoine-Roi Artaud. Both his parents were natives of Smyrna, and he was affected by his Greek ancestry. His mother gave birth to nine children, four out of the nine were stillborn and he contracted spinal meningitis at the age of 4. This disease has no cure, but after a long struggle including a comatose period, Artauds parents arranged a long series of sanatorium stays for their temperamental son, which were both prolonged and expensive. This lasted five years, with a break of two months in June and July 1916, when Artaud was conscripted into the French Army and he was allegedly discharged due to his self-induced habit of sleepwalking. During Artauds rest cures at the sanatorium, he read Arthur Rimbaud, Charles Baudelaire, in May 1919, the director of the sanatorium prescribed laudanum for Artaud, precipitating a lifelong addiction to that and other opiates. In March 1920, Artaud moved to Paris to pursue a career as a writer, while training and performing with directors including Charles Dullin and Georges Pitoeff, he continued to write both poetry and essays. Their compilation into a work, Correspondance avec Jacques Rivière, was Artauds first major publication. Artaud cultivated a great interest in cinema as well, writing the scenario for the first surrealist film, The Seashell and this film influenced Salvador Dalí and Luis Buñuel, two key Spanish surrealists, when they made Un Chien Andalou. Artauds performance as Jean-Paul Marat in Abel Gances Napoleon used exaggerated movements to convey the fire of Marats personality and he also played the monk Massieu in Carl Theodor Dreyers The Passion of Joan of Arc. In 1926-28, Artaud ran the Alfred Jarry Theatre, along with Roger Vitrac and he produced and directed original works by Vitrac, as well as pieces by Claudel and Strindberg. The theatre advertised that they would produce Artauds play Jet de sang in their 1926-1927 season, the Theatre was extremely short-lived, but was attended by an enormous range of European artists, including André Gide, Arthur Adamov, and Paul Valéry. In 1931, Artaud saw Balinese dance performed at the Paris Colonial Exposition, although he did not fully understand the intentions and ideas behind traditional Balinese performance, it influenced many of his ideas for theatre. Also during this year, Artauds First Manifesto for a Theatre of Cruelty was published in La Nouvelle Revue Française, it would appear as a chapter in The Theatre. In 1935, Artauds production of his adaptation of Shelleys The Cenci premiered, les Censi was a commercial failure, although it employed innovative sound effects-including the first theatrical use of the electronic instrument the Ondes Martenot—and had a set designed by Balthus. Artaud also studied and lived with the Tarahumaran people and experimented with peyote, recording his experiences, the content of this work closely resembles the poems of his later days, concerned primarily with the supernatural. Artaud also recorded his horrific withdrawal from heroin upon entering the land of the Tarahumaras, having deserted his last supply of the drug at a mountainside, he literally had to be hoisted onto his horse and soon resembled, in his words, a giant, inflamed gum. Artaud would return to later in life

Theatre
–
The performers may communicate this experience to the audience through combinations of gesture, speech, song, music, and dance. Elements of art, such as painted scenery and stagecraft such as lighting are used to enhance the physicality, presence, the specific place of the performance is also named by the word theatre as derived from the Ancient Greek θέατρον, itself from θεάομαι. Modern theatre, broadly defined, includes performances of plays and musical theatre, there are connections between theatre and the art forms of ballet, opera and various other forms. The city-state of Athens is where western theatre originated, participation in the city-states many festivals—and mandatory attendance at the City Dionysia as an audience member in particular—was an important part of citizenship. The Greeks also developed the concepts of dramatic criticism and theatre architecture, Actors were either amateur or at best semi-professional. The theatre of ancient Greece consisted of three types of drama, tragedy, comedy, and the satyr play, the origins of theatre in ancient Greece, according to Aristotle, the first theoretician of theatre, are to be found in the festivals that honoured Dionysus. The performances were given in semi-circular auditoria cut into hillsides, capable of seating 10, the stage consisted of a dancing floor, dressing room and scene-building area. Since the words were the most important part, good acoustics, the actors wore masks appropriate to the characters they represented, and each might play several parts. Athenian tragedy—the oldest surviving form of tragedy—is a type of dance-drama that formed an important part of the culture of the city-state. Having emerged sometime during the 6th century BCE, it flowered during the 5th century BCE, no tragedies from the 6th century BCE and only 32 of the more than a thousand that were performed in during the 5th century BCE have survived. We have complete texts extant by Aeschylus, Sophocles, and Euripides, the origins of tragedy remain obscure, though by the 5th century BCE it was institution alised in competitions held as part of festivities celebrating Dionysus. As contestants in the City Dionysias competition playwrights were required to present a tetralogy of plays, the performance of tragedies at the City Dionysia may have begun as early as 534 BCE, official records begin from 501 BCE, when the satyr play was introduced. More than 130 years later, the philosopher Aristotle analysed 5th-century Athenian tragedy in the oldest surviving work of dramatic theory—his Poetics, Athenian comedy is conventionally divided into three periods, Old Comedy, Middle Comedy, and New Comedy. Old Comedy survives today largely in the form of the surviving plays of Aristophanes. New Comedy is known primarily from the papyrus fragments of Menander. Aristotle defined comedy as a representation of people that involves some kind of blunder or ugliness that does not cause pain or disaster. In addition to the categories of comedy and tragedy at the City Dionysia, finding its origins in rural, agricultural rituals dedicated to Dionysus, the satyr play eventually found its way to Athens in its most well-known form. Satyrs themselves were tied to the god Dionysus as his loyal companions, often engaging in drunken revelry

Myron Krueger is an American computer artist who developed early interactive works. He is also considered to be one of the first generation virtual reality, while earning a Ph. D. in Computer Science at the University of Wisconsin–Madison, Krueger worked on a number of early interactive computer artworks. Krueger went on to develop Metaplay, an integration of visuals, sounds, in this, the computer was used to create a unique real-time relationship between the participants in the gallery and the artist in another building. In 1971, his Psychic space used a sensory floor to perceive the participants movements around the environment, a later project, Videoplace, was funded by the National Endowment for the arts and a two-way exhibit was shown at the Milwaukee Art Museum in 1975. In 1978, joined the science faculty at the University of Connecticut. Videoplace has been exhibited widely in both art and science contexts in the United States and Canada, and it was shown in Japan. It was included in the SIGGRAPH Art Show in 1985 and 1990, Videoplace was also the featured exhibit at SIGCHI in 1985 and 1989, and at the 1990 Ars Electronica Festival. Instead of taking the virtual reality track of head-mounted display and data glove, Krueger later used the hardware from Videoplace for another piece, Small Planet. In this work, participants are able to fly over a small, computer-generated, flying is done by holding ones arms out, like a child pretending to fly, and leaning left or right and moving up or down. Small Planet was shown at SIGGRAPH93, Interaction 97, Mediartech 98 and he envisioned the art of interactivity, as opposed to art that happens to be interactive. That is, the idea that exploring the space of interactions between humans and computers was interesting, the focus was on the possibilities of interaction itself, rather than on an art project, which happens to have some response to the user.

Microsoft HoloLens, known under development as Project Baraboo, is a pair of mixed reality smartglasses developed and manufactured by Microsoft. HoloLens gained popularity for being one of the first computers running the Windows Mixed Reality platform under the Windows 10 operating system, the HoloLens can trace its lineage to Kinect, an add-on for Microsofts Xbox gaming console that was introduced in 2010. The pre-production version of HoloLens, the Development Edition, shipped on March 30,2016, samsung and Asus have extended an offer to Microsoft to help produce their own mixed-reality products, in collaboration with Microsoft, based around the concept and hardware on HoloLens. The HoloLens is a display unit connected to an adjustable, cushioned inner headband. In the front is much of the sensors and related hardware, including the cameras, the visor is tinted, enclosed in the visor piece is a pair of transparent combiner lenses, in which the projected images are displayed in the lower half. The HoloLens must be calibrated to the distance, or accustomed vision of the user. Along the bottom edges of the side, located near the ears, are a pair of small. The speakers, competing against typical sound systems, do not obstruct external sounds, allowing the user to hear virtual sounds, on the top edge are two pairs of buttons, display brightness buttons above the left ear, and volume buttons above the right ear. Adjacent buttons are shaped differently—one concave, one convex—so that the user can distinguish them by touch, a USB2.0 micro-B receptacle is located along the bottom edge. A3.5 mm audio jack is located along the edge of the right arm. The SoC and the HPU each have 1GB LPDDR3 and share 8MB SRAM, with the SoC also controlling 64GB eMMC and running the Windows 10 operating system. The HPU uses 28 custom DSPs from Tensilica to process and integrate data from the sensors, as well as handling tasks such as mapping, gesture recognition. According to Alex Kipman, the HPU processes terabytes of information, the HoloLens contains an internal rechargeable battery, with average life rated at 2–3 hours of active use, or 2 weeks of standby time. The HoloLens can be operated while charging, HoloLens features IEEE802. 11ac Wi-Fi and Bluetooth 4.1 Low Energy wireless connectivity. The headset uses Bluetooth LE to pair with the included Clicker, the Clicker features a clickable surface for selecting, and an orientation sensor which provides for scrolling functions via tilting and panning of the unit. The Clicker features an elastic finger loop for holding the device, as of 2016, a number of augmented-reality applications have been announced or showcased for Microsoft HoloLens. A collection of applications will be provided for free for developers purchasing the Microsoft HoloLens Developer Edition, any user with skype of his regular devices like PC, Mobile etc. can dial user on HoloLens and communicate with each other. OnSight can be used in planning, with users able to program rover activities by looking at a target within the simulation

Open-source
–
Open-source software may be developed in a collaborative public manner. According to scientists who studied it, open-source software is a prominent example of open collaboration, a 2008 report by the Standish Group states that adoption of open-source software models has resulted in savings of about $60 billion per year to consumers. In the early days of computing, programmers and developers shared software in order to learn from each other, eventually the open source notion moved to the way side of commercialization of software in the years 1970-1980. In 1997, Eric Raymond published The Cathedral and the Bazaar and this source code subsequently became the basis behind SeaMonkey, Mozilla Firefox, Thunderbird and KompoZer. Netscapes act prompted Raymond and others to look into how to bring the Free Software Foundations free software ideas, the new term they chose was open source, which was soon adopted by Bruce Perens, publisher Tim OReilly, Linus Torvalds, and others. The Open Source Initiative was founded in February 1998 to encourage use of the new term, a Microsoft executive publicly stated in 2001 that open source is an intellectual property destroyer. I cant imagine something that could be worse than this for the software business, IBM, Oracle, Google and State Farm are just a few of the companies with a serious public stake in todays competitive open-source market. There has been a significant shift in the corporate philosophy concerning the development of FOSS, the free software movement was launched in 1983. In 1998, a group of individuals advocated that the free software should be replaced by open-source software as an expression which is less ambiguous. Software developers may want to publish their software with an open-source license, the Open Source Definition, notably, presents an open-source philosophy, and further defines the terms of usage, modification and redistribution of open-source software. Software licenses grant rights to users which would otherwise be reserved by law to the copyright holder. Several open-source software licenses have qualified within the boundaries of the Open Source Definition, the open source label came out of a strategy session held on April 7,1998 in Palo Alto in reaction to Netscapes January 1998 announcement of a source code release for Navigator. They used the opportunity before the release of Navigators source code to clarify a potential confusion caused by the ambiguity of the free in English. Many people claimed that the birth of the Internet, since 1969, started the open source movement, the Free Software Foundation, started in 1985, intended the word free to mean freedom to distribute and not freedom from cost. Since a great deal of free software already was free of charge, such software became associated with zero cost. The Open Source Initiative was formed in February 1998 by Eric Raymond and they sought to bring a higher profile to the practical benefits of freely available source code, and they wanted to bring major software businesses and other high-tech industries into open source. Perens attempted to open source as a service mark for the OSI. The Open Source Initiatives definition is recognized by governments internationally as the standard or de facto definition, OSI uses The Open Source Definition to determine whether it considers a software license open source

Gyroscope
–
A gyroscope is a spinning wheel or disc in which the axis of rotation is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum, because of this, gyroscopes are useful for measuring or maintaining orientation. Due to their precision, gyroscopes are used in gyrotheodolites to maintain direction in tunnel mining. Gyroscopes can be used to construct gyrocompasses, which complement or replace magnetic compasses, a gyroscope is a wheel mounted in two or three gimbals, which are a pivoted supports that allow the rotation of the wheel about a single axis. In the case of a gyroscope with two gimbals, the gimbal, which is the gyroscope frame, is mounted so as to pivot about an axis in its own plane determined by the support. This outer gimbal possesses one degree of freedom and its axis possesses none. The inner gimbal is mounted in the frame so as to pivot about an axis in its own plane that is always perpendicular to the pivotal axis of the gyroscope frame. This inner gimbal has two degrees of rotational freedom, the axle of the spinning wheel defines the spin axis. The rotor is constrained to spin about an axis, which is perpendicular to the axis of the inner gimbal. So the rotor possesses three degrees of freedom and its axis possesses two. The wheel responds to a force applied to the axis by a reaction force to the output axis. The behaviour of a gyroscope can be most easily appreciated by consideration of the front wheel of a bicycle. If the wheel is leaned away from the vertical so that the top of the moves to the left. In other words, rotation on one axis of the turning wheel produces rotation of the third axis, a gyroscope flywheel will roll or resist about the output axis depending upon whether the output gimbals are of a free or fixed configuration. Examples of some free-output-gimbal devices would be the attitude reference gyroscopes used to sense or measure the pitch, roll, the centre of gravity of the rotor can be in a fixed position. Some gyroscopes have mechanical equivalents substituted for one or more of the elements, for example, the spinning rotor may be suspended in a fluid, instead of being pivotally mounted in gimbals. In some special cases, the outer gimbal may be omitted so that the rotor has two degrees of freedom. Essentially, a gyroscope is a top combined with a pair of gimbals, Tops were invented in many different civilizations, including classical Greece, Rome, and China

Stereoscopic
–
Stereoscopy is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word stereoscopy derives from Greek στερεός, meaning firm, solid, any stereoscopic image is called a stereogram. Originally, stereogram referred to a pair of images which could be viewed using a stereoscope. Most stereoscopic methods present two offset images separately to the left and right eye of the viewer and these two-dimensional images are then combined in the brain to give the perception of 3D depth. Stereoscopy creates the illusion of depth from given two-dimensional images. One of the functions that occur within the brain as it interprets what the eyes see is assessing the relative distances of objects from the viewer, the two images are then combined in the brain to give the perception of depth. Although the term 3D is ubiquitously used, the presentation of dual 2D images is distinctly different from displaying an image in three full dimensions. The most notable difference is that, in the case of 3D displays, holographic displays and volumetric display do not have this limitation. Just as it is not possible to recreate a full 3-dimensional sound field with just two speakers, it is an overstatement to call dual 2D images 3D. The accurate term stereoscopic is more cumbersome than the common misnomer 3D, although most stereoscopic displays do not qualify as real 3D display, all real 3D displays are also stereoscopic displays because they meet the lower criteria also. Most 3D displays use this method to convey images. It was first invented by Sir Charles Wheatstone in 1838, but if it be required to obtain the most faithful resemblances of real objects, shadowing and colouring may properly be employed to heighten the effects. Flowers, crystals, busts, vases, instruments of various kinds, Stereoscopy is used in photogrammetry and also for entertainment through the production of stereograms. Stereoscopy is useful in viewing images rendered from large data sets such as are produced by experimental data. Modern industrial three-dimensional photography may use 3D scanners to detect and record three-dimensional information, the three-dimensional depth information can be reconstructed from two images using a computer by correlating the pixels in the left and right images. Solving the Correspondence problem in the field of Computer Vision aims to create meaningful depth information from two images, anatomically, there are 3 levels of binocular vision required to view stereo images, Simultaneous perception Fusion Stereopsis These functions develop in early childhood. Some people who have strabismus disrupt the development of stereopsis, however orthoptics treatment can be used to improve binocular vision, a persons stereoacuity determines the minimum image disparity they can perceive as depth. It is believed that approximately 12% of people are unable to properly see 3D images, according to another experiment up to 30% of people have very weak stereoscopic vision preventing them from depth perception based on stereo disparity

Processors
–
The computer industry has used the term central processing unit at least since the early 1960s. The form, design and implementation of CPUs have changed over the course of their history, most modern CPUs are microprocessors, meaning they are contained on a single integrated circuit chip. An IC that contains a CPU may also contain memory, peripheral interfaces, some computers employ a multi-core processor, which is a single chip containing two or more CPUs called cores, in that context, one can speak of such single chips as sockets. Array processors or vector processors have multiple processors that operate in parallel, there also exists the concept of virtual CPUs which are an abstraction of dynamical aggregated computational resources. Early computers such as the ENIAC had to be rewired to perform different tasks. Since the term CPU is generally defined as a device for software execution, the idea of a stored-program computer was already present in the design of J. Presper Eckert and John William Mauchlys ENIAC, but was initially omitted so that it could be finished sooner. On June 30,1945, before ENIAC was made, mathematician John von Neumann distributed the paper entitled First Draft of a Report on the EDVAC and it was the outline of a stored-program computer that would eventually be completed in August 1949. EDVAC was designed to perform a number of instructions of various types. Significantly, the programs written for EDVAC were to be stored in high-speed computer memory rather than specified by the wiring of the computer. This overcame a severe limitation of ENIAC, which was the considerable time, with von Neumanns design, the program that EDVAC ran could be changed simply by changing the contents of the memory. Early CPUs were custom designs used as part of a larger, however, this method of designing custom CPUs for a particular application has largely given way to the development of multi-purpose processors produced in large quantities. This standardization began in the era of discrete transistor mainframes and minicomputers and has accelerated with the popularization of the integrated circuit. The IC has allowed increasingly complex CPUs to be designed and manufactured to tolerances on the order of nanometers, both the miniaturization and standardization of CPUs have increased the presence of digital devices in modern life far beyond the limited application of dedicated computing machines. Modern microprocessors appear in electronic devices ranging from automobiles to cellphones, the so-called Harvard architecture of the Harvard Mark I, which was completed before EDVAC, also utilized a stored-program design using punched paper tape rather than electronic memory. Relays and vacuum tubes were used as switching elements, a useful computer requires thousands or tens of thousands of switching devices. The overall speed of a system is dependent on the speed of the switches, tube computers like EDVAC tended to average eight hours between failures, whereas relay computers like the Harvard Mark I failed very rarely. In the end, tube-based CPUs became dominant because the significant speed advantages afforded generally outweighed the reliability problems, most of these early synchronous CPUs ran at low clock rates compared to modern microelectronic designs. Clock signal frequencies ranging from 100 kHz to 4 MHz were very common at this time, the design complexity of CPUs increased as various technologies facilitated building smaller and more reliable electronic devices

Omnidirectional camera
–
In photography, an omnidirectional camera is a camera with a 360-degree field of view in the horizontal plane, or with a visual field that covers the entire sphere. Omnidirectional cameras are important in areas where large visual field coverage is needed, such as in panoramic photography, a camera normally has a field of view that ranges from a few degrees to, at most, 180°. This means that it captures, at most, light falling onto the focal point through a hemisphere. In contrast, an omnidirectional camera captures light from all directions falling onto the focal point. In the case that they cover the sphere, the captured light rays do not intersect exactly in a single focal point. Traditional approaches to panoramic photography mainly consists of stitching shots taken separately into a single, in contrast, an omnidirectional camera can be used to create panoramic art in real time, without the need for post processing, and will typically give much better quality products. In 2015 Facebook began rolling out omnidirectional videos where the user can view the video at any arbitrary camera angle around a 360-degree radius, in robotics, omnidirectional cameras are frequently used for visual odometry and to solve the simultaneous localization and mapping problems visually. Due to its ability to capture a 360-degree view, better results can be obtained for optical flow and feature selection, applications of omnidirectional cameras also include surveillance, when it is important to cover an as large visual field as possible.

Photogrammetry
–
Photogrammetry is the science of making measurements from photographs, especially for recovering the exact positions of surface points. It may also be used to recover the motion pathways of designated reference points on any moving object, on its components, and in the immediately adjacent environment. Photogrammetric analysis may be applied to one photograph, or may use high-speed photography and remote sensing to detect, measure, the quantitative results of photogrammetry are then used to guide and match the results of computational models of the natural systems. Photogrammetry is as old as photography, dating to the mid-19th century. Its detection component has been emerging from radiolocation, multilateration and radiometry and its 3-D positioning estimative component employs methods related to triangulation, trilateration and multidimensional scaling. This is done by multiplying the distance by 1/s. Photogrammetry uses methods from many disciplines, including optics and projective geometry, digital image capturing and photogrammetric processing includes several well defined stages, which allow to generate 2D or 3D digital models of the object as an end product. The data model on the right shows what type of information can go into, the 3-D co-ordinates define the locations of object points in the 3-D space. The image co-ordinates define the locations of the object points images on the film or an imaging device. The exterior orientation of a camera defines its location in space, the inner orientation defines the geometric parameters of the imaging process. This is primarily the focal length of the lens, but can include the description of lens distortions. Each of the four main variables can be an input or an output of a photogrammetric method, algorithms for photogrammetry typically attempt to minimize the sum of the squares of errors over the coordinates and relative displacements of the reference points. This minimization is known as bundle adjustment and is performed using the Levenberg–Marquardt algorithm. Common points are identified on each image, a line of sight can be constructed from the camera location to the point on the object. It is the intersection of these rays determines the three-dimensional location of the point. Stereophotogrammetry is emerging as a robust non-contacting measurement technique to determine dynamic characteristics, photogrammetric data with a dense range data in which scanners complement each other. Photogrammetry is more accurate in the x and y direction while range data are more accurate in the z direction. Photos can clearly define the edges of buildings when the point cloud footprint can not and it is beneficial to incorporate the advantages of both systems and integrate them to create a better product

View-Master
–
It was manufactured and sold by Sawyers. The View-Master system was introduced in 1939, four years after the advent of Kodachrome color film made the use of small high-quality photographic color images practical. Tourist attraction and travel views predominated in View-Masters early lists of available reels, most current View-Master reels are intended for children. Edwin Eugene Mayer worked as a pharmacist at Owl Drug store in downtown Portland and he built up a photo-finishing business there, and bought into Sawyers Photo Finishing Service in 1919 with the help of his father August Mayer, his fiancee Eva McAnulty, and her sister Vi McAnulty. The company relocated to a large building at 181 Ella St. near Morrison Street in Portland. The company was producing photographic postcards and album sets as souvenirs by 1926, Graves handled marketing for the products while Mayer ran the business. Later, photographic greeting cards were added to the Sawyers product line, Sawyers was the nations largest producer of scenic postcards in the 1920s and the future View-Master viewer eventually became an extension of the two-dimensional cards. Mayer and Gruber had both developed devices for viewing images, but Gruber had made up a stereo imaging rig out of two Kodak Bantam Specials mounted together on a tripod. He designed a machine that mounted the tiny pieces of Kodachrome color transparency film into reels made from heavy paper stock, a special viewer was also designed and produced. He had the idea of updating the old-fashioned stereoscope by using the new Kodachrome 16-mm color film, a View-Master reel holds 14 film transparencies in seven pairs, making up the seven stereoscopic images. The components of each pair are viewed simultaneously, one by each eye, according to a 1960 court document, the Gruber-Sawyer partner venture began from that first meeting in 1938. Thereafter, Ed Mayer negotiated with Gruber while production methods and some marketing were developed, after three years, a formal agreement was entered into on February 24,1942 between Gruber and Sawyer partners, doing business as Sawyers. Ed Mayer and people within the Sawyer’s organization were uncertain what to call their new product, the View-Master was introduced at the 1939 New York Worlds Fair, marked Patent Applied For. It was intended as an alternative to the postcard, and was originally sold at photography shops, stationery stores. The main subjects of View-Master reels were Carlsbad Caverns and the Grand Canyon, the View-Master was marketed through Ed Mayers photo-finishing, postcard, and greeting card company Sawyers Service, Inc. known eventually as Sawyers, Inc. The partnership led to the sales of View-Master viewers and reels. The patent on the device was issued in 1940, on what came to be called the Model A viewer. Within a very time, the Viewmaster took over the postcard business at Sawyers.00 and Western Photo Supply Co. owning the buildings

Science fiction
–
Science fiction often explores the potential consequences of scientific and other innovations, and has been called a literature of ideas. Science fiction is difficult to define, as it includes a range of subgenres and themes. Author and editor Damon Knight summed up the difficulty, saying science fiction is what we point to when we say it, a definition echoed by author Mark C. Glassy, who argues that the definition of science fiction is like the definition of pornography, you do not know what it is, in 1970 or 1971William Atheling Jr. According to science fiction writer Robert A, rod Serlings definition is fantasy is the impossible made probable. Science fiction is the improbable made possible, Science fiction is largely based on writing rationally about alternative possible worlds or futures. Science fiction elements include, A time setting in the future, in alternative timelines, a spatial setting or scenes in outer space, on other worlds, or on subterranean earth. Characters that include aliens, mutants, androids, or humanoid robots, futuristic or plausible technology such as ray guns, teleportation machines, and humanoid computers. Scientific principles that are new or that contradict accepted physical laws, for time travel, wormholes. New and different political or social systems, e. g. utopian, dystopian, post-scarcity, paranormal abilities such as mind control, telepathy, telekinesis Other universes or dimensions and travel between them. A product of the budding Age of Reason and the development of science itself. Isaac Asimov and Carl Sagan considered Keplers work the first science fiction story and it depicts a journey to the Moon and how the Earths motion is seen from there. Later, Edgar Allan Poe wrote a story about a flight to the moon, more examples appeared throughout the 19th century. Wells The War of the Worlds describes an invasion of late Victorian England by Martians using tripod fighting machines equipped with advanced weaponry and it is a seminal depiction of an alien invasion of Earth. In the late 19th century, the scientific romance was used in Britain to describe much of this fiction. This produced additional offshoots, such as the 1884 novella Flatland, the term would continue to be used into the early 20th century for writers such as Olaf Stapledon. In the early 20th century, pulp magazines helped develop a new generation of mainly American SF writers, influenced by Hugo Gernsback, the founder of Amazing Stories magazine. In 1912 Edgar Rice Burroughs published A Princess of Mars, the first of his series of Barsoom novels, situated on Mars

Stanley G. Weinbaum
–
Stanley Grauman Weinbaum was an American science fiction writer. His career in fiction was short but influential. His first story, A Martian Odyssey, was published to acclaim in July 1934, but he succumbed to lung cancer less than a year. Weinbaum was born in Louisville, Kentucky, the son of Stella and he attended the University of Wisconsin–Madison in Madison, first as a chemical engineering major but later switching to English as his major, but contrary to common belief he did not graduate. On a bet, Weinbaum took an exam for a friend and he is best known for the groundbreaking science fiction short story, A Martian Odyssey, which presented a sympathetic but decidedly non-human alien, Tweel. Even more remarkably, this was his first science fiction story, isaac Asimov has described A Martian Odyssey as a perfect Campbellian science fiction story, before John W. Campbell. Indeed, Tweel may be the first creature in science fiction to fulfil Campbells dictum, write me a creature who thinks as well as a man, or better than a man, but not like a man. Asimov went on to describe it as one of three stories that changed the way all subsequent ones in the science fiction genre were written. It is the oldest short story selected by the Science Fiction Writers of America for inclusion in The Science Fiction Hall of Fame, Volume One, most of the work that was published in his lifetime appeared in either Astounding or Wonder Stories. However, several of Weinbaums pieces first appeared in the early fanzine Fantasy Magazine in the 1930s, despite common belief, Weinbaum was not one of the contributors to the multi-authored Cosmos serial in Science Fiction Digest/Fantasy Magazine. He did contribute to the multi-author story The Challenge From Beyond, at the time of his death, Weinbaum was writing a novel, Three Who Danced. In this novel, the Prince of Wales is unexpectedly present at a dance in an obscure American community, each girls life is changed as a result of the unexpected attention she receives. In 1993, his widow, Margaret Hawtof Kay, donated his papers to the Temple University Library in Philadelphia, Pennsylvania, included were several unpublished manuscripts, among them Three Who Danced, as well as other unpublished stories. A film version of his short story The Adaptive Ultimate was released in 1957 under the title She Devil, starring Mari Blanchard, Jack Kelly, the story was also dramatized on television, a Studio One titled Kyra Zelas aired on September 12,1949. A radio dramatization of The Adaptive Ultimate was performed on the anthology show Escape in the 1950s, a crater on Mars is named in his honor. On July 18,2008, he won the Cordwainer Smith Rediscovery Award, lester del Rey declared that Weinbaum, more than any other writer, helped to take our field out of the doldrums of the early thirties and into the beginnings of modern science fiction. H. P. Frederik Pohl wrote that, before Weinbaum, science fictions aliens might be catmen, lizard-men, antmen, plantmen or rockmen, but they were, always and incurably, men. It was the difference in orientation -- in drives, goals and thought processes -- that made the Weinbaum-type alien so fresh, everett F. Bleiler, however, reported that although Weinbaum was generally considered the most promising new s-f author of his day, his reputation is overstated

The Sensorama was a machine that is one of the earliest known examples of immersive, multi-sensory technology. He dubbed it Experience Theater, and detailed his vision of multi-sensory theater in his 1955 paper entitled The Cinema of the Future, in 1962 he built a prototype of his vision, dubbed the Sensorama, along with five short films for it to display. The Sensorama was a device, which still functions today. The Sensorama was able to display stereoscopic 3-D images in a view, provide body tilting, supply stereo sound. Oddly enough in hindsight, Heilig was simply unable to obtain financial backing for his visions and patents, and so the Sensorama work was halted.

Gary DellAbate, also known as Baba Booey, is an American radio producer, and has been the executive producer of The Howard Stern Show since 1984. His autobiography, They Call Me Baba Booey, was released on November 2,2010, DellAbate was born and raised in Uniondale, New York, on Long Island. He comes from a large Italian-American family and his father, Salvatore DellAbate, was a salesman for Hagen Daz ice cream, while his mother was a food demonstartor at Macys in New York City and Fortunoffs on Long Island. DellAbate attended Adelphi University, receiving the Richard F. Clemo Award his senior year, while interning with Roz Frank, a traffic reporter on WNBC, he came into contact with Howard Stern. DellAbate has worked on The Howard Stern Show since September 4,1984, originally on 66 WNBC, then syndicated through K-Rock in New York City, DellAbate was originally hired for $150 a week, with duties including getting Sterns lunch and scheduling guests for the show. Previously nicknamed Boy Gary, DellAbates Baba Booey moniker originated on The Howard Stern Show on July 26,1990, in the course of discussing a Quick Draw McGraw cel he might purchase, he misstated the name of McGraws sidekick Baba Looey as Baba Booey. Speaking to Howard at the end of the show, DellAbate said, Howard Stern replied, Gary, weve only scratched the surface of this. DellAbate remains Baba Booey to this day, eventually he titled his autobiography They Call Me Baba Booey. DellAbate later recalled that when he watched the cartoon as a child, Quick Draw would often call Baba Looey Baba Boy, Quick Draws drawn-out pronunciation of boy often sounded like booey, which led DellAbate to think that the characters name was actually Baba Booey. Baba Booey as a term has become a mantra for fans of The Howard Stern Show and is used during crank calls to live network television or radio broadcasts. For example, a made to ABC News during the low-speed police chase of O. J. Simpsons Ford Bronco through the streets of Brentwood, Los Angeles, California. Sportscaster Al Michaels explained to anchor Peter Jennings the significance of the phrase, more recently, Freestyle wrestler Jake Herbert yelled Baba Booey as the camera panned over Team USA during the opening ceremony of the 2012 Olympic Games. Beginning in 2013, there have been hundreds of instances on the PGA Tour in which spectators have shouted Baba Booey. as soon as a golfer has completed his swing, DellAbate has been married since 1992 to Mary DellAbate. They have two sons, Lucas and Jackson, after DellAbates brother Steven died of AIDS in January 1991, DellAbate became a supporter of LIFEbeat The Music Industry Fights AIDS and serves as the charitys president. DellAbate wrote a biography titled They Call Me Baba Booey which was a New York Times best seller and it debuted at #6 on the NY Times Best Seller list in November of 2010. In the book DellAbate tells the story of his brothers death from AIDS and he was featured in the May 2007 issue of Sound and Vision magazine where his home theater was profiled. DellAbate is an avid New York Mets fan, and, on May 9,2009 he threw out the ceremonial first pitch at a Mets game, the pitch did not go well, as it landed down the third-base line and hit an umpire. DellAbate is also a fan of the New York Islanders hockey team, DellAbates thoughts and memories of following the Islanders are featured throughout the book, as well as several photos of DellAbate with Islanders players at a Stanley Cup victory parade in 1980

Douglas Carl Engelbart was an American engineer and inventor, and an early computer and Internet pioneer. These were demonstrated at The Mother of All Demos in 1968, Engelbarts Law, the observation that the intrinsic rate of human performance is exponential, is named after him. In the early 1950s, he decided instead of having a steady job – such as his position at NASAs Ames Research Center – he would focus on making the world a better place. He believed that the computer, which was at the thought of only as a tool for automation. He was a committed, vocal proponent of the development and use of computers and computer networks to help cope with the increasingly urgent. Engelbart embedded a set of organizing principles in his lab, which he termed bootstrapping and his belief was that when human systems and tool systems were aligned, such that workers spent time improving their tools for improving their tools it would lead to an accelerating rate of progress. The lab was transferred from SRI to Tymshare in the late 1970s, which was acquired by McDonnell Douglas in 1984, at both Tymshare and McDonnell Douglas, Engelbart was limited by a lack of interest in his ideas and funding to pursue them, and retired in 1986. In December 2000, United States President Bill Clinton awarded Engelbart the National Medal of Technology, in December 2008, Engelbart was honored by SRI at the 40th Anniversary celebration of the 1968 Mother of All Demos. Engelbart was born in Portland, Oregon on January 30,1925, to Carl Louis Engelbart and his ancestors were of German, Swedish and Norwegian descent. He was the middle of three children, with a sister Dorianne, and a brother David, the family lived in Portland, Oregon, in his early years, and moved to the surrounding countryside along Johnson Creek when he was 8. His father died one year later and he graduated from Portlands Franklin High School in 1942. On a small island, in a hut on stilts, he read Vannevar Bushs article As We May Think. He returned to Oregon State College and completed his bachelors degree in engineering in 1948. While at Oregon State College, he was a member of Sigma Phi Epsilon social fraternity and he was hired by the National Advisory Committee for Aeronautics at the Ames Research Center, where he worked in wind tunnel maintenance. In his off hours he enjoyed hiking, camping, and folk dancing and it was there he met Ballard Fish who was just completing her training to become an occupational therapist. They were married on May 5,1951 in Portola State Park, soon after, Engelbart left NACA to pursue a PhD at UC Berkeley. Engelbarts career was inspired in December 1950 when he was engaged to be married and realized he had no goals other than a steady job, getting married. In 1945, Engelbart had read with interest Vannevar Bushs article As We May Think and he had also read something about the recent phenomenon of computers, and from his experience as a radar technician, he knew that information could be analyzed and displayed on a screen

Ivan Edward Sutherland is an American computer scientist and Internet pioneer, widely regarded as the father of computer graphics. His early work in graphics as well as his teaching with David C. Evans in that subject at the University of Utah in the 1970s was pioneering in the field. Sutherland, Evans, and his students from that era invented several foundations of computer graphics. He is a member of the National Academy of Engineering, as well as the National Academy of Sciences among many major awards. In 2012 he was awarded the Kyoto Prize in Advanced Technology for pioneering achievements in the development of computer graphics and interactive interfaces. Sutherland earned his Bachelors degree in engineering from the Carnegie Institute of Technology, his masters degree from Caltech. He invented Sketchpad in 1962 while at MIT, Professor Claude Shannon signed on to supervise Sutherland’s computer drawing thesis. Among others on his thesis committee were Marvin Minsky and Steven Coons, Sketchpad was an innovative program that influenced alternative forms of interaction with computers. Sketchpad could accept constraints and specified relationships among segments and arcs and it could draw both horizontal and vertical lines and combine them into figures and shapes. Figures could be copied, moved, rotated, or resized, Sketchpad also had the first window-drawing program and clipping algorithm, which allowed zooming. Sketchpad ran on the Lincoln TX-2 computer and influenced Douglas Engelbarts oN-Line System, Sketchpad, in turn, was influenced by the conceptual Memex as envisioned by Vannevar Bush in his influential paper As We May Think. Sutherland replaced J. C. R. Licklider as the head of the US Defense Department Advanced Research Project Agencys Information Processing Techniques Office, from 1965 to 1968, Sutherland was an Associate Professor of Electrical Engineering at Harvard University. Work with student Danny Cohen in 1967 led to the development of the Cohen–Sutherland computer graphics line clipping algorithm, in 1968, with the help of his student Bob Sproull, he created the first virtual reality and augmented reality head-mounted display system, named The Sword of Damocles. From 1968 to 1974, Sutherland was a professor at the University of Utah, in 1968 he co-founded Evans and Sutherland with his friend and colleague David C. Evans. The company has done pioneering work in the field of hardware, accelerated 3D computer graphics. Former employees of Evans and Sutherland included the founders of Adobe. From 1974 to 1978 he was the Fletcher Jones Professor of Computer Science at California Institute of Technology and he then founded a consulting firm, Sutherland, Sproull and Associates, which was purchased by Sun Microsystems to form the seed of its research division, Sun Labs. Sutherland was a Fellow and Vice President at Sun Microsystems, Sutherland was a visiting scholar in the Computer Science Division at University of California, Berkeley

Head-mounted display
–
A head-mounted display, both abbreviated HMD, is a display device, worn on the head or as part of a helmet, that has a small display optic in front of one or each eye. A HMD has many uses including in gaming, aviation, engineering, there is also an optical head-mounted display, which is a wearable display that can reflect projected images and allows a user to see through it. A typical HMD has one or two small displays, with lenses and semi-transparent mirrors embedded in eyeglasses, a visor, or a helmet, the display units are miniaturised and may include cathode ray tubes, liquid crystal displays, liquid crystal on silicon, or organic light-emitting diodes. Some vendors employ multiple micro-displays to increase resolution and field of view. HMDs differ in whether they can display only computer-generated imagery, or only live imagery from the physical world, most HMDs can display only a computer-generated image, sometimes referred to as a virtual image. Some HMDs can allow a CGI to be superimposed on a real-world view and this is sometimes referred to as augmented reality or mixed reality. Combining real-world view with CGI can be done by projecting the CGI through a partially reflective mirror and this method is often called optical see-through. Combining real-world view with CGI can also be done electronically by accepting video from a camera and this method is often called video see-through. An optical head-mounted display uses an optical mixer which is made of partly silvered mirrors and it can reflect artificial images, and let real images cross the lens, and let a user look through it. Various methods have existed for see-through HMDs, most of which can be summarized into two families based on curved mirrors or waveguides. Curved mirrors have been used by Laster Technologies, and by Vuzix in their Star 1200 product, various waveguide methods have existed for years. These include diffraction optics, holographic optics, polarized optics, major HMD applications include military, government, and civilian-commercial. In 1962, Hughes Aircraft Company revealed the Electrocular, a compact CRT, ruggedized HMDs are increasingly being integrated into the cockpits of modern helicopters and fighter aircraft. These are usually integrated with the pilots flying helmet and may include protective visors, night vision devices. Military, police, and firefighters use HMDs to display information such as maps or thermal imaging data while viewing a real scene. Recent applications have included the use of HMD for paratroopers, in 2005, the Liteye HMD was introduced for ground combat troops as a rugged, waterproof lightweight display that clips into a standard US PVS-14 military helmet mount. The self-contained color monocular organic light-emitting diode display replaces the NVG tube, the LE has see-through ability and can be used as a standard HMD or for augmented reality applications. The design is optimized to provide high definition data under all lighting conditions, the LE has a low power consumption, operating on four AA batteries for 35 hours or receiving power via standard Universal Serial Bus connection

User interface
–
The user interface, in the industrial design field of human–computer interaction, is the space where interactions between humans and machines occur. Examples of this concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls. The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology. Generally, the goal of user interface design is to produce a user interface makes it easy, efficient. This generally means that the needs to provide minimal input to achieve the desired output. Other terms for user interface are man–machine interface and when the machine in question is a computer human–computer interface, the user interface or human–machine interface is the part of the machine that handles the human–machine interaction. Membrane switches, rubber keypads and touchscreens are examples of the part of the Human Machine Interface which we can see. In complex systems, the interface is typically computerized. The term human–computer interface refers to this kind of system, in the context of computing the term typically extends as well to the software dedicated to control the physical elements used for human-computer interaction. The engineering of the interfaces is enhanced by considering ergonomics. The corresponding disciplines are human factors engineering and usability engineering, which is part of systems engineering, tools used for incorporating human factors in the interface design are developed based on knowledge of computer science, such as computer graphics, operating systems, programming languages. Nowadays, we use the graphical user interface for human–machine interface on computers. There is a difference between a user interface and an interface or a human–machine interface. A human-machine interface is typically local to one machine or piece of equipment, an operator interface is the interface method by which multiple equipment that are linked by a host control system is accessed or controlled. The system may expose several user interfaces to serve different kinds of users, for example, a computerized library database might provide two user interfaces, one for library patrons and the other for library personnel. The user interface of a system, a vehicle or an industrial installation is sometimes referred to as the human–machine interface. HMI is a modification of the original term MMI, in practice, the abbreviation MMI is still frequently used although some may claim that MMI stands for something different now. Another abbreviation is HCI, but is commonly used for human–computer interaction

Realism (arts)
–
Realism in the arts is the attempt to represent subject matter truthfully, without artificiality and avoiding artistic conventions, implausible, exotic and supernatural elements. Realism has been prevalent in the arts at many periods, and is in part a matter of technique and training. In the visual arts, illusionistic realism is the depiction of lifeforms, perspective. Realist works of art may emphasize the mundane, ugly or sordid, such as works of realism, regionalism. There have been various movements in the arts, such as the opera style of verismo, literary realism, theatrical realism. The realism art movement in painting began in France in the 1850s, the realist painters rejected Romanticism, which had come to dominate French literature and art, with roots in the late 18th century. Realism is the precise, detailed and accurate representation in art of the appearance of scenes. Realism in this sense is also called naturalism, mimesis or illusionism, realistic art was created in many periods, and it is in large part a matter of technique and training, and the avoidance of stylization. It becomes especially marked in European painting in the Early Netherlandish painting of Jan van Eyck, however such realism is often used to depict, for example, angels with wings, which were not things the artists had ever seen in real life. It is the choice and treatment of matter that defines Realism as a movement in painting. The development of increasingly accurate representation of the appearances of things has a long history in art. It includes elements such as the depiction of the anatomy of humans and animals, of perspective and effects of distance. Ancient Greek art is recognised as having made great progress in the representation of anatomy. Pliny the Elders famous story of birds pecking at grapes painted by Zeuxis in the 5th century BC may well be a legend, roman portraiture, when not under too much Greek influence, shows a greater commitment to a truthful depiction of its subjects. The art of Late Antiquity famously rejected illusionism for expressive force, scientific methods of representing perspective were developed in Italy and gradually spread across Europe, and accuracy in anatomy rediscovered under the influence of classical art. As in classical times, idealism remained the norm, intriguingly, having led the development of illusionic painting, still life was to be equally significant in its abandonment in Cubism. The depiction of ordinary, everyday subjects in art also has a history, though it was often squeezed into the edges of compositions. However these objects are at least largely there because they carry layers of complex significance, pieter Bruegel the Elder pioneered large panoramic scenes of peasant life

Wire-frame model
–
A wire-frame model is a visual presentation of a 3-dimensional or physical object used in 3D computer graphics. It is created by specifying each edge of the object where two mathematically continuous smooth surfaces meet, or by connecting an objects constituent vertices using straight lines or curves. The object is projected into space by drawing lines at the location of each edge. The term wire frame comes from designers using metal wire to represent the shape of solid objects. 3D wire frame allows to construct and manipulate solids and solid surfaces, the 3D solid modeling technique efficiently draws higher quality representations of solids than the conventional line drawing. Using a wire-frame model allows visualization of the design structure of a 3D model. Traditional two-dimensional views and drawings can be created by appropriate rotation of the object, since wire-frame renderings are relatively simple and fast to calculate, they are often used in cases where a high screen frame rate is needed. When greater graphical detail is desired, surface textures can be added automatically after completion of the rendering of the wire frame. This allows the designer to quickly review solids or rotate the object to new desired views without long delays associated with more realistic rendering, the wire frame format is also well suited and widely used in programming tool paths for direct numerical control machine tools. Hand-drawn wire-frame-like illustrations date back as far as the Italian Renaissance, wire-frame models are also used as the input for computer-aided manufacturing. There are mainly three types of 3D CAD models, wire frame is one of them and it is the most abstract and least realistic. Other types of 3D CAD models are surface and solid and this method of modelling consists of only lines, points and curves defining the edges of an object. Wireframing is one of the used in geometric modelling systems. A wireframe model represents the shape of an object with its characteristic lines. There are two types of modelling, Pros and Cons. In Pros user gives a simple input to create a shape and it is useful in developing systems. While in Cons wireframe model, it does not include information about inside and outside boundary surfaces, today, wireframe models are used to define complex solid objects. The designer makes a model of a solid object, and then the CAD operator reconstructs the object

Battlezone (1980 video game)
–
Battlezone is a first-person tank combat arcade game from Atari released in November 1980. The player controls a tank which is attacked by other tanks, the game uses wireframe vector graphics on a black and white vector monitor. It was designed primarily by Ed Rotberg, who designed many games for Atari Inc, gameplay is on a plane with a mountainous horizon featuring an erupting volcano, distant crescent moon, and various geometric solids like pyramids and blocks. The player views the screen, which includes an overhead view to find and destroy the rather slow tanks. Saucer-shaped UFOs and guided missiles occasionally appear for a bonus opportunity, the saucers differ from the tanks in that they do not fire upon the player, and do not appear on radar. The player can hide behind the solids or maneuver in rapid turns once fired on to buy time with which to fire himself. No additional tanks are awarded until the score counter rolls over at ten million, the game only includes one hostile enemy on the game board at all times, the player never has to battle two enemy tanks at once, or a tank and guided missile. The UFO can appear on the screen at the time as an enemy tank. The geometric solid obstacles are indestructible, and can block the movement of a players tank, however, they are also useful as shields as they block enemy fire as well. The music heard when a score of 100,000 is attained, Battlezone was housed in a standard upright arcade cabinet with a novel periscope viewfinder which the player used to view the game. The game action could also be viewed from the sides of the viewfinder for spectators to watch, a later, less common version of the cabinet removed the periscope to improve visibility to non-players and improve the ergonomics for players who could not reach the periscope. This modification also was welcomed by some operators, who felt that the windows present in the periscoped version did not attract enough attention to the game when played. A smaller version of the cabinet also existed with the screen angled upwards, a cocktail table version was tested as a prototype but not produced, it lacked the color overlays as the display would have to flip for opposing players. The controls consisted of left and right joysticks, which could only be moved in the Y axis, one joystick contained a button used to fire projectiles at enemy targets. A version called The Bradley Trainer was also designed for use by the U. S. Army as targeting training for gunners on the Bradley Fighting Vehicle. Approaching Atari in December 1980, some developers within Atari refused to work on the project because of its association with the Army, Rotberg only came on board after he was promised by management that he would never be asked to do anything with the military in the future. The gunner yoke was based on the Bradley Fighting Vehicle control and was later re-used in the popular Star Wars game. The Bradley Trainer differs dramatically from the original Battlezone as it features helicopters, missiles, and machine guns, furthermore, Battlezone was well received, earning an Honorable Mention for Best Commercial Arcade Game in 1982 at the Third Annual Arkie Awards

Aspen Movie Map
–
The Aspen Movie Map was a revolutionary hypermedia system developed at MIT by a team working with Andrew Lippman in 1978 with funding from ARPA. The Aspen Movie Map enabled the user to take a tour through the city of Aspen. It is an example of a hypermedia system. A gyroscopic stabilizer with four 16mm stop-frame film cameras was mounted on top of a car with an encoder that triggered the cameras every ten feet, the distance was measured from an optical sensor attached to the hub of a bicycle wheel dragged behind the vehicle. The cameras were mounted in order to capture front, back, filming took place daily between 10 a. m. and 2 p. m. to minimize lighting discrepancies. The car was driven down the center of every street in Aspen to enable registered match cuts. The film was assembled into a collection of scenes and then transferred to laserdisc. A database was made that correlated the layout of the video on the disc with the street plan. Commands were sent from the client process handling the input and overlay graphics to a server that accessed the database. Another interface feature was the ability to any building in the current field of view. In a later implementation, the metadata, which was in large part automatically extracted from the database, was encoded as a digital signal in the analog video. The data encoded in each frame contained all the information to enable a full-featured surrogate-travel experience. Aspen was filmed in early fall and winter, the user was able to in situ change seasons on demand while moving down the street or looking at a façade. These computer-graphic images, also stored on the laserdisc, were correlated to the video. MIT undergraduate Peter Clay, with help from Bob Mohl and Michael Naimark, the film was transferred to a laserdisc as part of a collection of projects being done at the Architecture Machine Group. The Aspen Movie Map was filmed in the fall of 1978, in winter 1979, the first version was operational in early spring of 1979. ARPA funding during the late 1970s was subject to the application requirements of the Mansfield Amendment introduced by Mike Mansfield. The Aspen Movie Maps military application was to solve the problem of quickly familiarizing soldiers with new territory

Massachusetts Institute of Technology

The Massachusetts Institute of Technology is a private research university in Cambridge, Massachusetts, often cited as one of the worlds most prestigious universities. Researchers worked on computers, radar, and inertial guidance during World War II, post-war defense research contributed to the rapid expansion of the faculty and campus under James Killian. The current 168-acre campus opened in 1916 and extends over 1 mile along the bank of the Charles River basin. The Institute is traditionally known for its research and education in the sciences and engineering, and more recently in biology, economics, linguistics. Air Force and 6 Fields Medalists have been affiliated with MIT, the school has a strong entrepreneurial culture, and the aggregated revenues of companies founded by MIT alumni would rank as the eleventh-largest economy in the world. In 1859, a proposal was submitted to the Massachusetts General Court to use newly filled lands in Back Bay, Boston for a Conservatory of Art and Science, but the proposal failed. A charter for the incorporation of the Massachusetts Institute of Technology, Rogers, a professor from the University of Virginia, wanted to establish an institution to address rapid scientific and technological advances. The Rogers Plan reflected the German research university model, emphasizing an independent faculty engaged in research, as well as instruction oriented around seminars, two days after the charter was issued, the first battle of the Civil War broke out. After a long delay through the war years, MITs first classes were held in the Mercantile Building in Boston in 1865, in 1863 under the same act, the Commonwealth of Massachusetts founded the Massachusetts Agricultural College, which developed as the University of Massachusetts Amherst. In 1866, the proceeds from sales went toward new buildings in the Back Bay. MIT was informally called Boston Tech, the institute adopted the European polytechnic university model and emphasized laboratory instruction from an early date. Despite chronic financial problems, the institute saw growth in the last two decades of the 19th century under President Francis Amasa Walker. Programs in electrical, chemical, marine, and sanitary engineering were introduced, new buildings were built, the curriculum drifted to a vocational emphasis, with less focus on theoretical science. The fledgling school still suffered from chronic financial shortages which diverted the attention of the MIT leadership, during these Boston Tech years, MIT faculty and alumni rebuffed Harvard University president Charles W. Eliots repeated attempts to merge MIT with Harvard Colleges Lawrence Scientific School. There would be at least six attempts to absorb MIT into Harvard, in its cramped Back Bay location, MIT could not afford to expand its overcrowded facilities, driving a desperate search for a new campus and funding. Eventually the MIT Corporation approved an agreement to merge with Harvard, over the vehement objections of MIT faculty, students. However, a 1917 decision by the Massachusetts Supreme Judicial Court effectively put an end to the merger scheme, the neoclassical New Technology campus was designed by William W. Bosworth and had been funded largely by anonymous donations from a mysterious Mr. Smith, starting in 1912. In January 1920, the donor was revealed to be the industrialist George Eastman of Rochester, New York, who had invented methods of production and processing

Aspen, Colorado

Aspen is the Home Rule Municipality that is the county seat and the most populous municipality of Pitkin County, Colorado, United States. Its population was 6,658 at the 2010 United States Census, founded as a mining camp during the Colorado Silver Boom and later named Aspen because of the abundance of aspen trees in the area, the city boomed during the 1880s, its first decade of existence. In the late 20th century, the city became a retreat for celebrities. Gonzo journalist Hunter S. Thompson worked out of a downtown hotel, singer John Denver wrote two songs about Aspen after settling there. Today the musicians and movie stars have been joined by corporate executives, as a result of this influx of wealth, Aspen boasts some of the most expensive real estate prices in the United States and many middle-class residents can no longer afford to live there. It remains a popular tourist destination, with outdoor recreation in the surrounding White River National Forest serving as a complement to the four ski areas in the vicinity. Production expanded due to the passage of the Sherman Silver Purchase Act of 1890, by 1893, Aspen had banks, a hospital, a police department, two theaters, an opera house and electric lights. Economic collapse came with the Panic of 1893, when President Cleveland called a session of Congress. Within weeks, many of the Aspen mines were closed and thousands of miners were put out of work, eventually, after wage cuts, mining revived somewhat, but production declined and by the 1930 census only 705 residents remained. Remaining, however, were fine stocks of old buildings and residences. Aspens development as a ski resort first flickered in the 1930s when investors conceived of a ski area, friedl Pfeifer, a member of the 10th Mountain Division who had trained in the area, returned to the area and linked up with industrialist Walter Paepcke and his wife Elizabeth. The Aspen Skiing Corporation was founded in 1946 and the city became a well-known resort. Paepcke also played an important role in bringing the Goethe Bicentennial Convocation to Aspen in 1949, Aspen was now on the path to becoming an internationally known ski resort and cultural center, home of the Aspen Music Festival and School. The area would continue to grow with the development of three ski areas, Buttermilk, Aspen Highlands, and Snowmass. In 1977, notorious serial killer Ted Bundy, while in the Pitkin County Courthouse in Aspen for a hearing, jumped from a second-story window. He remained free for six days, hiding out on Aspen Mountain, in 1977, Aspen was thoroughly photographed for the Aspen Movie Map project funded by the U. S. Department of Defense. The Movie Map is one of the earliest examples of virtual reality software, Aspen is notable as the smallest radio market tracked by Arbitron, ranked at #302. Aspen is a Home Rule Municipality under Colorado law, an elected council of four members and the mayor supervise the citys operations, managed on a day-to-day basis by the city manager, an appointed official who serves at their pleasure

North American video game crash of 1983
–
The North American video game crash of 1983 was a massive recession in the video game industry that occurred from 1983 to 1985. Revenues had peaked at around $3.2 billion in 1983, the crash was a serious event that brought an abrupt end to what is retrospectively considered the second generation of console video gaming in North America. The crash almost destroyed the industry, and led to the bankruptcy of several companies producing home computers. Analysts of the time expressed doubts about the viability of video game consoles. The crash had several causes, including the saturation of the market, the full effects of the industry crash would not be felt until 1985. The North American video game crash of 1983 was caused by a combination of factors. At the time of the North American crash, there were many consoles on the market, including the Atari 2600, Atari 5200, ColecoVision, Odyssey 2 and the Fairchild II. Each of these consoles had its own library of games produced by the console maker, the first microcomputers such as the Altair 8800 and Apple I were marketed to a niche of electronics hobbyists as most required assembly from a kit. In 1977, pre-assembled machines with BASIC in ROM became available, including the Trio of 77, the Apple II, Commodore PET, the latter two retailed for under $1,000, but lacked game joysticks and high-resolution color video. Third-party developers created games for all of these platforms, the TRS-80 benefited from Radio Shacks retail stores, which displayed computers and accessories locally in an era where many personal computers were mail-ordered from manufacturers. In 1979, Atari unveiled the Atari 400 and 800 computers, built around a chipset originally meant for use in a console. In 1981, IBM introduced the IBM5150 PC with a $1,565 base price, by 1982, new desktop computer designs were commonly providing better color graphics and sound than game consoles and personal computer sales were booming. The TI 99/4A and the Atari 400 were both at $349, Radio Shacks Color Computer sold at $379, and Commodore International had just reduced the price of the VIC-20 to $199, by 1983 consumers found that most predicted uses of home computers were unrealistic, except for games. Children used most home computers—Coleco planned to market its Adam home computer to boys age 8 to 16, the two groups that really fuel computer purchases—so games dominated home computers software libraries. A1984 compendium of reviews of Atari 8-bit software used 198 pages for games compared to 167 for all other software types, because computers generally had more memory and faster processors than a console, they permitted more sophisticated games. They could also be used for such as word processing. Games were easier to duplicate, since they could be packaged as floppy disks or cassette tapes instead of ROM modules and this opened the field to a cottage industry of third-party software developers. Writeable storage media allowed players to save games in progress, a feature for increasingly complex games which was not available on the consoles of the era

Jaron Zepel Lanier is an American computer philosophy writer, computer scientist, visual artist, and composer of classical music. A pioneer in the field of reality, Lanier and Thomas G. Zimmerman left Atari in 1985 to found VPL Research. In the late 1990s, Lanier worked on applications for Internet2, from 2006 he began to work at Microsoft, and from 2009 forward he works at Microsoft Research as Interdisciplinary Scientist. Lanier was the director of a short film, Muzork. In 2010, Lanier was nominated in the TIME100 list of most influential people, born Jaron Zepel Lanier in New York City, Lanier was raised in Mesilla, New Mexico. Laniers mother and father were Jewish, his mother was a camp survivor from Vienna. When he was nine years old, his mother was killed in a car accident and he lived in tents for an extended period with his father before embarking on a seven-year project to build a geodesic dome home that he helped design. At the age of 13, Lanier convinced New Mexico State University to let him enroll, at NMSU, he took graduate-level courses, he received a grant from the National Science Foundation to study mathematical notation, which led him to learn computer programming. From 1979 to 1980, the NSF-funded project at NMSU focused on digital graphical simulations for learning, Lanier also attended art school in New York during this time, but returned to New Mexico and worked as a midwife. The father of a baby he helped deliver him a car as a gift. In California, Lanier worked for Atari, where he met Thomas Zimmerman, after Atari Inc. was split into two companies in 1984, Lanier became unemployed. The free time enabled him to concentrate on his own projects, including VPL, along with Zimmerman, Lanier founded VPL Research, focusing on commercializing virtual reality technologies, the company prospered for a while, but filed for bankruptcy in 1990. In 1999, Sun Microsystems bought VPLs virtual reality and graphics-related patents, the Initiative demonstrated the first prototypes of tele-immersion in 2000 after a three-year development period. From 2001 to 2004, he was Visiting Scientist at Silicon Graphics Inc. where he developed solutions to problems in telepresence. While transistor count increases according to Moores law, overall performance rises only very slowly, according to Lanier, this is because human productivity in developing software increases only slightly, and software becomes more bloated and remains as error-prone as it ever was. Simply put, software just wont allow it, code cant keep up with processing power now, and it never will. At the end he warns that the biggest problem of any theory is not that it is false, the impression of objective necessity paralyzes the ability of humans to walk out of or to fight the paradigm and causes the self-fulfilling destiny which spoils people. Some of Laniers speculation involves what he calls post-symbolic communication, Lanier sees this behavior, especially as exchanged between two octopodes, as a direct behavioral expression of thought

Daniel J. Sandin is a video and computer graphics artist/researcher. He is a Professor Emeritus of the School of Art & Design, University of Illinois at Chicago and he is an internationally recognized pioneer in computer graphics, electronic art and visualization. Dan Sandin received his B. A. in Natural Sciences from Shimer College, IL in 1964 and he became interested in video in 1967, while helping to organize student demonstrations at the University of Illinois. His major achievements were a series of projects Glowflow, Sandin Image Processor, Sayre Glove, PHSColograms, CAVE and ImmersaDesk and Infinity Wall. From 1971 to 1973, he designed the Sandin Image Processor and this modular design was based on the Moog synthesizer. With Tom DeFanti, he would combine it with computer graphics and synthesized music. His piece Spiral PTL was one of the first pieces included in the Museum of Modern Arts video art collection. In 1977, with Tom DeFanti and Rich Sayre, he designed the Sayre Glove and this device used light based sensors with flexible tubes with a light source at one end and a photocell at the other. As the fingers were bent, the amount of light hit the photocells varied. It was mainly used to manipulate sliders, but was lightweight, by 1988, Sandin was working on a type of digital photography called PHSColograms, a system whereby a number of still images were situated in an autostereoscopic manner and back-projected with light. The effect was similar to holograms and many times viewers would mistake them as such. The initial system supported roughly 13 images but further improvements now could easily allow 100 such images to be used and this system was designed primarily for use in the medical field where these quasi-3D images could benefit surgeons. The first CAVE was invented by Carolina Cruz-Neira, Daniel J. Sandin and this is an immersive system that became the standard for rear projection-based Virtual Reality systems. The normal full system consists of projections screens along the front, side and floor axes, since then there have been a couple offshoots of the CAVE technology, including ImmersaDesk, Infinity Wall and Oblong Industries G-speak system. The ImmersaDesk is a system, resembling a drafting table, while the Infinity Wall is designed to cater to an entire room of people. Extending this concept, G-speak supports gestural input from multiple-users and multiple-devices on,5 Minute Romp through the Image Processor.

The Electronic Visualization Laboratory is a cross-disciplinary research lab at the University of Illinois at Chicago. It brings together faculty and students from the Art and Computer Science departments of UIC, the primary areas of research are in computer graphics, high-performance computer networking, and technological art. EVL represents one of the oldest art and engineering collaborations in the United States and it was founded in 1973 by Tom DeFanti and Dan Sandin. The lab was known as the Circle Graphics Habitat, in reference to the then-name of UIC. DeFanti and Sandin have served as Co-Directors of the lab since its founding, later in 1987, they were joined by Maxine D. Brown as Associate Director. Work at EVL over the years has included,1977, The Sayre Glove,1981, The Z Box hardware and ZGRASS software, an early graphics system for the Bally home computer. This system featured NTSC video output and was used by a number of computer graphics artists of the time,1988, Computer generated PHSColograms, an autostereoscopic 3D technique, with n. 1992, The CAVE Automatic Virtual Environment, a virtual reality system. 1995, The I-WAY event at Supercomputing 95, a prototype of grid computing,1997, The STAR TAP project, a linking up of several international high-performance networks. Followed by the StarLight optical networking facility, highlights of the electronic art work done at EVL include, Electronic Visualization Events in the mid 1970s - live, real-time performances featuring computer graphics, video processing, and music. Early computer graphics art videos, created by combining DeFantis GRASS system on a PDP-11, the video Spiral PTL was included in the inaugural collection of video art at the Museum of Modern Art. Computer artist Larry Cuba spent time at EVL, using the tools there for his films 3/78 and Calculated Movements, in 1996, EVL installed the first publicly accessible CAVE at the Ars Electronica Center in Austria, and presented a number of virtual reality artworks. The members of EVL have been involved with the SIGGRAPH organization, DeFanti has served as Secretary and Chair of the organization, and 1979 conference chair. Brown has served as Vice Chair for Operations and Secretary, according to Jim Blinn, the popular Electronic Theatre started out as a bunch of people crowding into Dan Sandin’s dorm room to watch videotapes. In 1979, DeFanti established the SIGGRAPH Video Review, which EVL has continued to supervise, at SIGGRAPH92, EVL organized the Showcase event, where researchers demonstrated 35 projects in state-of-the-art computational science and scientific visualization. At SIGGRAPH94, EVL organized the VROOM event, demonstrations of the state of virtual reality technology, in 1998, Brown received the first ever SIGGRAPH Outstanding Service Award for her contributions to the organization.

Cave automatic virtual environment
–
A cave automatic virtual environment is an immersive virtual reality environment where projectors are directed to between three and six of the walls of a room-sized cube. The name is also a reference to the allegory of the Cave in Platos Republic in which a philosopher contemplates perception, reality, a CAVE is typically a video theater situated within a larger room. The walls of a CAVE are typically made up of rear-projection screens, the floor can be a downward-projection screen, a bottom projected screen or a flat panel display. The projection systems are very high-resolution due to the near distance viewing which requires very small pixel sizes to retain the illusion of reality, the user wears 3D glasses inside the CAVE to see 3D graphics generated by the CAVE. People using the CAVE can see objects apparently floating in the air and this was initially made possible by electromagnetic sensors, but has converted to infrared cameras. A CAVE users movements are tracked by the sensors typically attached to the 3D glasses, computers control both this aspect of the CAVE and the audio aspect. There are typically multiple speakers placed at angles in the CAVE. A lifelike visual display is created by projectors positioned outside the CAVE, a motion capture system records the real time position of the user. Stereoscopic LCD shutter glasses convey a 3D image, the computers rapidly generate a pair of images, one for each of the users eyes, based on the motion capture data. The glasses are synchronized with the projectors so that each eye sees the correct image. Since the projectors are positioned outside the cube, mirrors are used to reduce the distance required from the projectors to the screens. One or more computers drive the projectors, clusters of desktop PCs are popular to run CAVEs, because they cost less and run faster. Software and libraries designed specifically for CAVE applications are available, there are several techniques for rendering the scene. There are 3 popular scene graphs in use today, OpenSG, OpenSceneGraph, OpenSG and OpenSceneGraph are open source, while OpenGL Performer is free, its source code is not included. CAVELib is the original application programmers interface developed for the CAVE system created at the Electronic Visualization Lab at University of Illinois Chicago, the software was commercialized in 1996 and further enhanced by Mechdyne Corporation. Developers create all of the graphics for their environment and the CAVELib makes it display properly, the CAVELib API is platform-independent, enabling developers to create high-end virtual reality applications on Windows and Linux operating systems. CAVELib-based applications are externally configurable at run-time, making an application independent of the display system. Mechdynes Conduit is a software package that makes a small number of existing 3D OpenGL application work directly in a CAVE

Holodeck
–
The holodeck, and holographic technology in general, is a plot device used in stories set within the Star Trek universe. It is used to stories with locations and characters that could not otherwise exist in the Star Trek setting. Although Star Treks conception of technology is fictional, some scientists have predicted that virtual reality tools similar to the holodeck will become a consumer-ready product by 2024. Most holodeck programs shown in the run in first person subjective mode, in which the user actively interacts with the program. Writer Phil Farrand has often pointed out how in many episodes matter from the holodeck that gets on a person still exists when the real person exits the holodeck. In Encounter at Farpoint, Wesley Crusher falls into a holodeck stream, in The Big Goodbye, Picard has lipstick on his cheek after encountering a holodeck simulation of a 20th-century woman. In Elementary, Dear Data, Data and Geordi La Forge exit the holodeck with a piece of paper that originated in the holodeck and this could be explained using replicated rather than holographic matter. In most episodes, the holodeck is controlled by voice commands and they also include safety protocols to protect the users. Some users may develop an addiction to the holodeck, leading to them spending unhealthy amounts of time there and this was demonstrated by the Starfleet human character Reginald Barclay in the Voyager episode Pathfinder and The Next Generation episode Hollow Pursuits. In the timeline of the universe, the concept of a holodeck was first shown to humans in an encounter with the Xyrillian race in the Star Trek. In real-time, the holodeck is first presented as a called the Rec room within the Star Trek animated series (released in 1974. During the episode The Practical Joker, Dr McCoy, Sulu, Holodeck variations of being by the sea, in a forest, falling down a pit and being trapped in a snow-storm all having physical characteristics place the lives of McCoy, Sulu and Uhura at risk. When they were running from the Borg on his starship they hid in the holodeck, the Star Trek Holodeck was inspired by New York inventor and holographer, Gene Dolgoff, who is also the inventor of the digital projector. His holography laboratory, built in 1964, was the first holography lab in New York City, in 1973, Dolgoff was giving a technical paper on his holographic model of the human brain at a conference in Prague. There he met Melanie Toyofuku, also based in New York, Dolgoff had won 4th prize in the student paper contest in 1968 in which he described how such a holographic TV system could work. Roddenberry wrote the concept into Star Trek, The Next Generation, however, the concept had already been tested in 1974 in Star Trek, the Animated Series. Starfleet personnel use holodecks for training, diagnostics and recreation, the Emergency Medical Hologram on ships such as USS Voyager applies holodeck technology to present a single character within the otherwise natural environment of the ships sick bay. An example of the holodecks recreational functions are the holosuites that are owned and rented out—often for sexual purposes—by Quark on Deep Space Nine, writing stories and plotlines for the holodeck is an activity pursued by people known as holonovelists

Virtual fixture
–
A virtual fixture is an overlay of augmented sensory information on a workspace in order to improve human performance in direct and remotely manipulated tasks. Developed in the early 1990s by Louis Rosenberg at the US Air Force, virtual fixtures was a platform in virtual reality. Virtual Fixtures was first developed by Louis Rosenberg in 1992 at the USAF Armstrong Labs, the result was a spatially-registered immersive experience in which the user moved his or her arms, while seeing robot arms in the place where his or her arms should be. The system also employed computer-generated virtual overlays in the form of simulated physical barriers, fields, the concept of virtual fixtures was first introduced in as an overlay of virtual sensory information on a workspace in order to improve human performance in direct and remotely manipulated tasks. The virtual sensory overlays can be presented as physically realistic structures, the virtual sensory overlays can also be abstractions that have properties not possible of real physical structures. The concept of sensory overlays is difficult to visualize and talk about, to understand what a virtual fixture is an analogy with a real physical fixture such as a ruler is often used. A simple task such as drawing a line on a piece of paper on free-hand is a task that most humans are unable to perform with good accuracy. However, the use of a device such as a ruler allows the task to be carried out fast. The use of a ruler helps the user by guiding the pen along the ruler reducing the tremor and mental load of the user, the definition of virtual fixtures in is much broader than simply providing guidance of the end-effector. For example, auditory virtual fixtures are used to increase the awareness by providing audio clues that helps the user by providing multi modal cues for localization of the end-effector. This is the type of virtual fixtures that is described in this article, Virtual fixtures can be either guiding virtual fixtures or forbidden regions virtual fixtures. A forbidden regions virtual fixture could be used, for example, such illegal commands could easily be sent by an operator because of, for instance, delays in the teleoperation loop, poor telepresence or a number of other reasons. With both forbidden regions and guiding virtual fixtures the stiffness, or its inverse the compliance, of the fixture can be adjusted, If the compliance is high the fixture is soft. On the other hand, when the compliance is zero the fixture ishard and this section describes how a control law that implements virtual fixtures can be derived. It is assumed that the robot is a purely kinematic device with end-effector position p =, the input control signal u to the robot is assumed to be a desired end-effector velocity v = x ˙ =. In a tele-operated system it is useful to scale the input velocity from the operator. If the input from the user is of another such as a force or position it must first be transformed to an input velocity. Thus the control signal u would be computed from the input velocity v op as
