Optimal Combination of the Binocular Cues to 3D Motion

摘要

PURPOSE. Perception necessarily entails combining separate sensory estimates into a single coherent whole. The perception of three-dimensional (3D) motion, for instance, can rely on two binocular cues: one related to the change in binocular disparity over time (CD) and the other related to interocular velocity differences (IOVD). Although previous work has shown that neither cue is strictly necessary for the perception of 3D motion, observers are able to judge 3D motion in displays in which one or the other cue has been eliminated, it is unclear whether or how the two cues are combined in situations in which both are present.
