Abstract

A user interface method includes defining an interaction surface containing an interaction region in space. A sequence of depth maps is captured over time of at least a part of a body of a human subject. The depth maps are processed in order to detect a direction and speed of movement of the part of the body as the part of the body passes through the interaction surface. A computer application is controlled responsively to the detected direction and speed.
