Abstract
A user can emulate touch screen events with motions and gestures that the user performs at a distance from a computing device. A user can utilize specific gestures, such as a pinch gesture, to designate portions of motion that are to be interpreted as input, to differentiate from other portions of the motion. A user can then perform actions such as text input by performing motions with the pinch gesture that correspond to words or other selections recognized by a text input program. A camera-based detection approach can be used to recognize the location of features performing the motions and gestures, such as a hand, finger, and/or thumb of the user.
