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.

A cursor positioning system for a data terminal having a display, comprising: A. a first radiation source and an associated first radiation sensor, wherein the radiation characteristics of one of said first source and first sensor has a substantially omnidirectional pattern over a predetermined angu

A cursor positioning system for a data terminal having a display, comprising: A. a first radiation source and an associated first radiation sensor, wherein the radiation characteristics of one of said first source and first sensor has a substantially omnidirectional pattern over a predetermined angular segment, the radiation characteristic of the other of said first source and first sensor corresponds to the superposition of a plurality of directional patterns extending substantially from a single point, said plurality of patterns being substantially uniformly distributed over partially overlapping predetermined angular segments, said first sensor including means for generating a sensor signal associated with each of said directional patterns, said sensor signals being related to the radiational coupling between said first source and first sensor, B. means for fixing the position of one of said first source and first sensor with respect to said display and for fixing the position of the other of said first source and first sensor with respect to the head of an operator of said system, C. motion processing means responsive to said sensor signals and including means for extracting operator motion signals from said sensor signals and for generating position signals therefrom representative of the orientation of the operator\s head, said extracting means including means for suppressing portions of said sensor signal representative of predetermined operator head motions, and D. means for generating cursor signals adapted for controlling the position of a cursor on said display in response to said position signals.
