ABSTRACT:
A controller provides control signals to a computer based upon the movement of a user. The controller has an optical detector for detecting and monitoring the movement of a user, particularly movement of selected body parts, and circuitry for outputting a control signal to the computer in accordance with detected movement. A vector indicative of detected movement is generated on a frame-to-frame basis using only a few representative edge pixels of the body parts. Control signals for the direction and the velocity of the movement are determined from the vector and move a graphical user interface on a display accordingly.
