Abstract: Researchers especially beginning with Rogers and Graham, 1982 have noticedimportant psychophysical and experimental similarities between theneurologically different motion parallax and stereopsis cues. Theirquantitative analysis relied primarily on the -disparity equivalence-approximation. In this article we show that retinal motion from lateraltranslation satisfies a strong -asymptotic- approximation to binoculardisparity. This precise mathematical similarity is also practical in the sensethat it applies at normal viewing distances. The approximation is an extensionto peripheral vision of Cormac and Fox-s 1985 well-known non-trig centralvision approximation for binocular disparity. We hope our simple algebraicformula will be useful in analyzing experiments outside central vision whereless precise approximations have led to a number of quantitative errors in thevision literature.
