The figural charasteristics of visual object represented in ⊿ fransformed coordinate system shows the character of shape constancy in some conditions in spite of the lack of slant perception, and this character is named virtual constancy. About this, it was examined with the same experimental conditions that had been carried out previously, resulting the virtual constancy contributes respectable part of the experimental index of constancy. The effect of virtual constancy on the change of constancy were investigated, it was found the virtual constancy decreases with the increase of slant of object against frontal parallel, and increases with the increase of visual angle about the object which have been known as the experimental fact. Moreover, the shape constancy in condition of wide visual angle like a perspective of an interior is represented sufficieutly well by ⊿ transformation system, and investigating the results of previous experiment, their data correspond with the estimated character of virtual constancy. These facts show that the perception of shape in the perspective vision is a very fundamental factor in visual space perception. Further, the data of alley experiment which had been performed previously was examined, it was suggested not the existence only frontal parallel perspective vision but also inclined perspective vision.
