Outline of Final Research Achievements

Effects of target motion on human depth perception from very large binocular disparity were examined. Specifically, (i) dependency on stimulus motion direction, (ii) on observer motion direction, (iii) on target size (spatial frequency), (iv) on target velocity (temporal frequency), (v) effects of static target displacement, (vi) influence of motion on monoptic depth were examined.
The results showed that prominent facilitation was obtained (i) when two point stimuli moved horizontally in counter phase, (ii) when an observer oscillated horizontally, not back and forth, (iii) at about 0.3 c/deg, (iv) at about 4 Hz and that this is a (v) dynamic (vi) binocular effect.
