Interactive art is a form of art that involves the spectator in a way that allows the art to achieve its purpose. Some interactive art installations achieve this by letting the observer walk through, over or around them; others ask the artist or the spectators to become part of the artwork in some way.

Installation art is an artistic genre of three-dimensional works that are often site-specific and designed to transform the perception of a space. Generally, the term is applied to interior spaces, whereas exterior interventions are often called public art, land art or art intervention; however, the boundaries between these terms overlap.
