==Interaction methods==
Various methods of interaction exist in surface computing. The most common method of which is touch based, this includes single and [[multi-touch]] interactions. Other interactions exist such as freehand 3D interactions that depth-aware cameras can sense.
 
•'''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 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.
