M. Ichikawa et S. Saida, HOW IS MOTION DISPARITY INTEGRATED WITH BINOCULAR DISPARITY IN-DEPTH PERCEPTION, Perception & psychophysics, 58(2), 1996, pp. 271-282
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.
