Abstract

A global shape judgement task was used to investigate the combination of Stereopsis and kinetic depth. With both cues present, there were no distortions of shape perception, even under conditions where either cue alone did show such distortions. We suggest that the addition of motion information overcomes the stereo distance scaling problem. However, when incongruent combinations of disparity and morion were used, the results did not match predictions of a number of combination theories. These data could be described by a model which used weighted linear combination after correctly scaling disparities for viewing distance. When the motion cue was weakened by presenting only two frames of each motion sequence, stereo was weighted more heavily.
