Line 28:
•'''Two Dimensional''' Typically, traditional surface types are two-dimensional and only require two-dimensional touch interactions. Depending on the system, multi-touch gestures, such as [[pinch to zoom]], are supported. These gestures allow the user to manipulate what they see on the surface by physically touching it and moving their fingers them across the surface. For sufficiently large surfaces, multi-touch gestures can extend to both hands, and even multiple sets of hands in multi-user applications.
•'''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 [[DepthTouch]].<ref name=":1">[http://research.microsoft.com/en-us/um/people/benko/publications/2009/benko_mm09bnt236.pdf Beyond Flat Surface Computing: Challenges of Depth-Aware and Curved Interfaces]</ref> 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.
