ABSTRACT:
A simulator which provides competing and opposing stimuli for objects appearing to approach or retreat from the user in order to reduce simulator sickness. A simulator controller (92) monitors the pixels taken up by an object. When an object appears to take up more pixels, the controller interprets the object as appearing to approach the user (96). The controller inserts a complementary object which appears to do the opposite of the primary object detected by the simulator controller (92). Both objects are displayed on a video display (94) viewed by the user (96).
