A selfie stick is used to take photographs or video by positioning a digital camera device, typically a smartphone, beyond the normal range of the arm. This allows for shots to be taken at angles and distances that would not have been possible with the human arm by itself. The sticks are typically extensible, with a handle on one end and an adjustable clamp on the other end to hold the device in place. As their name suggests, they are most commonly used for taking selfies with camera phones.

A selfie is a self-portrait photograph or a short video, typically taken with an electronic camera or smartphone. The camera would be usually held at arm's length or supported by a selfie stick instead of being controlled with a self-timer or remote. The concept of shooting oneself while viewing their own image in the camera's LCD monitor is also known as self-recording.
