HOW IS MOTION DISPARITY INTEGRATED WITH BINOCULAR DISPARITY IN-DEPTH PERCEPTION

Two experiments presented motion disparity conflicting with binocular disparity to examine how these cues determined apparent depth order (c onvex, concave) and depth magnitude. In each experiment, 8 subjects es timated the depth order and depth magnitude. The first experiment show ed the following. (1) The visual system used one of these cues exclusi vely in selecting a depth order for each display. (2) The visual syste m integrated the depth magnitude information from these cues by a weig hted additive fashion if it selected the binocular disparity in depth order perception and if the depth magnitude specified by motion dispar ity was small relative to that specified by binocular disparity. (3) T he visual system ignored the depth magnitude information of binocular disparity if it selected the motion disparity in depth order perceptio n. The second experiment showed that these three points were consisten t whether the subject's head movement or object movement generated mot ion disparity.
