ABSTRACT:
A computer input system for input of data to a computer from a remote location by a human operator. The computer input system includes a detecting means which remotely detects the movement of a point object, such as an operator's nose, and a processing means for converting the detected motion into an output signal. The output signal may be used by a computer to move an image within a picture on a display. The detecting means detects the motion of the point object by detecting a ray which is reflected from or radiated by the point object.
