Retinal relative motion is able to be interpreted in various ways, typically in three patterns, rigid rotation, rigid translation, and nonrigid motion. Thus, Retinal relative motion is ambiguous. We, however, rarely experience such ambiguity. This implies that a mechanism reducing such ambiguity exists in the visual system. In the experiments, random dots were used for stimuli. Dots have moved in velocity gradients, which include two components, compress motion and shearing motion. Both are cue for the same rotation, although each represents different relative motion. Experiments revealed that coexistence of compress motion and shearing motion increases perception of rotation, on the one hand decreases perception of relative motion. These results suggest that accumulation of cue reduces interpretation ambiguity of retinal relative motion.
