Two Binocular Cues for Motion-in-depth

抄録

There are two binocular cues for motion-in-depth, interocular velocity difference (IOVD) and changing disparity over time (CDOT). To understand how the visual system deals with information obtained from the world, investigation of available cues for certain functions is indispensable, particularly when there are more than one. We review studies to investigate how the two cues contribute to the perception of motion-in-depth, focusing on the method to isolate these cues. The summary suggests that it is likely that both of IOVD and CDOT cues contribute to motion-in-depth nontrivial way while IOVD might be more important.
