| Outline of Final Research Achievements |
The role of the body in visual information processing was examined by psychophysical experiments. The results revealed that our visual system uses the information of the inter-ocular/inter-pupil distance to comprehend the depth (3D structure) of the external world based on binocular retinal disparity. It was also found that the body’s movement range restricts the function of constancy scaling, which leads to a distortion in the appearance of the body shape. These results suggest that our body plays an important role as a framework for interpreting ambiguous retinal images, and thus, it is important for studies of visual perception to take the influence of the body into consideration.
