ABSTRACT:
The present invention relates to a line-of-sight measuring system. The system comprises a passive optical pointing device which measures the relative change in line-of-sight of a focusing reflector attached to a target such as the operator of the device, located within a prescribed three dimensional space. The system utilizes a source of light adjacent a position sensing detector which source of light causes light to be reflected off the focusing reflector amd back to the position sensing detector. In this way, the line-of-sight between the object within the prescribed space and a particular location on a two dimensional screen positioned adjacent the prescribed space may be determined with great accuracy. The present invention also includes the electronic circuitry which interfaces the present invention with a computer such as a personal computer including an input keyboard and a display screen. Other applications of the present invention are also disclosed herein.
