Abstract
A computer system replaces an input device, such as a mouse, with a video camera having an image recognizing function and an image extracting function to detect motions of the operator's body directly, and controls a computer apparatus to move a cursor and check on an icon on the basis of the output signals of the video camera. The computer system controls the computer apparatus also on the basis of a signal provided by the video camera upon the detection of light emitted by a particular object. The computer system is capable of making the computer apparatus understand an operator's intention without using any conventional input device, such as a mouse, and of facilitating an operator's input operation.
