Abstract

We displayed the object of cones put on invisible sphere rotating in depth, and made the subjects observe it. They could perceive not only the three-dimensional shape of sphere but also the illusory transparent material filled in the sphere. Several authors (Nakayama, K., et al., 1990 ; etc.) have reported about the transparent perception on a plane, but little has been discussed about the transparent perception on the solid surface. In order to study what can induce the illusory transparent solid, we examined the relation between the number of cones and the size of sphere. The results suggested that the transparency could be perceived when the numbers of cones were arranged enough along the contours of sphere. We conclude that the unpaired region between temporally sequential images appears along the occluding contour can induce the illusory transparent solid.
