Abstract
It is generally thought that human beings have high-performance system in body movement. However, the mechanisms of body movement have not been clarified completely. It is believed that human beings unconsciously estimate the spatial depth from the two-dimensional figure projected on the retina to understand the three-dimensional space. This paper focuses on relations between human motion and vision in order to reveal mechanisms between human motion and cognition. In this study, we attempt to examine the effect of Miiller-Lyer illusion, which is a typical optical illusion, on human cognition and motion by using motion capture system. Based on the examination, this paper discusses an interaction between human motion and human cognition.
