Abstract:

A system that uses the computer more efficiently in computer generated image displays by allocating priority status to the area being viewed by the observer while progressively diminishing the resolution requirements of the displayed scene toward its perimeter. The video signal corresponds to the orientation of the observer's head which is ascertained by head and eye trackers, and provides a variable level of detail that tends to match the visual acuity of the human eye.
