•Three Dimensional Using depth aware cameras it is possible to make three dimensional gestures. Such gestures allow the user to move in three dimensions of space without having to come into contact with the surface itself, such as the methods used in Depth perception. DepthTouch makes use of a depth-sensing camera, a projector, desktop computer, and a vertical screen for the user to interact with. Instead of physically touching the screen, the user can manipulate the objects he or she sees displayed onto it by making freehand gestures in mid-air. The depth-aware camera can then detect the user's gestures and the computer processes them to show what the user is doing on the display.
