抄録(英) | Motion parallax, motion disparities yoked to the observers' head movements, is one of the usefull depth cues. The present study examined depth perception from motion parallax in various positions in the visual field. In Experiment 1, random dots patterns, containing given extents of motion parallax, were presented at various eccentricities. The result showed that the magnitude of perceived depth from constant motion parallax decreased with eccentricity. This could result from the properties in the relative motion perception at the peripheral vision. To examine this possibility, in Experiment 2, extents of motion parallax within stimuli for each eccentricity were determined in a way that the magnitude of perceived relative motion from the stimuli were equal for each observer. As a result, the magnitude of perceived depth decreased with eccentricity. When the spatial frequency of the velocity gradient, thus that of the depth corrugation, were varied in Experiment 3, the perceived depth decreased with eccentricity at all spatial frequencies. These results suggest that the peripheral vision is relatively inefficient in perceiving parallactic depth, and the depth processing from relative motion has different properties from the relative motion processing. |
