Motion parallax is a monocular depth cue that can provide a vivid and reliable depth percept.
We asked whether people with different forms of low vision could use motion parallax to improve depth judgements, and how the improvement compared with that of normal subjects. Subjects monocularly viewed 3 vertical cylinders and indicated which one was at a different depth than the other two. For static trials, the viewing assembly was fixed in place. These data were compared to data from normal-vision subjects with a range of simulated deficits in acuity and contrast sensitivity. These findings indicate that motion parallax is a robust depth cue across a wide range of visual deficit.
