Abstract
A cursor control system for use with a data terminal having a display consists of a radiation source and associated radiation sensor. Either the source or sensor is fixed with respect to the display while the other is moveable and may be fixed to the user's head. The system translates the motion of the user's head into a directional signal for controlling cursor position on the screen.
