Abstract
There are two binocular cues for perception of motion in depth. One is binocular disparity changes in time and the other is velocity differences between the len and right retinal images(inter-ocular velocity differences). We investigated the individual variation of the use of the two cues for perceiving motion in depth. We found that 18 of 25 observers(72%)could use inter-ocular velocity differences. 24 observers(96%)could use disparity change in time. These results suggest that inter-ocular velocity differences as well as disparity change in the is useful to see motion in depth.
