| Outline of Final Research Achievements |
Binocular disparity, the differences between the images on two eyes, is one of the important cues for depth perception. In this study, we aimed to classify the individual differences in stereopsis which is the depth perception from binocular disparity and to identify the causes for the individual differences. We measured disparity threshold, upper limit to detect disparity and relative contribution of binocular disparity and texture cues for depth perception and compared them to the state of eye refraction and personal past experience of visual space for each participant. We also examined the methods to measure stereopsis efficiently. Results showed that there was a significant difference in stereopsis and suggest that the difference in the experience of space environment would be one of the causes for the individual difference in stereopsis.
