Message for Students

Research means revealing new facts that nobody has ever known. Discovering a new fact is very difficult, but the pleasure of it is very large. If you find a new fact that only you can find in the graduate school, it should be wonderful.

Research Contents

I am studying visual information processing in the brain, especially how motion information of moving objects is processed in the visual system. I am also interested in emotional impressions of colors and forms, Japanese onomatopoeia, structure of human personality, origami (paper folding) and psychological data analysis.　

Attractive Factors of My Research

We see things without special effort. In fact, however, an enormous amount of information is processed for seeing objects. Computers have become superior to humans in recognition to some specified objects, but humans are still much better than computers at recognizing various kinds of objects in various environments. Investigating into the human visual system, which can accomplish very difficult tasks without trouble, is very exciting and meaningful. There are many mysteries in human behaviors and psychology, and it is important to elucidate them to understand humans.

Achievements

In experiencing flight simulator, we feel moving in an environment even if we do not actually move. This phenomenon indicates that humans perceive their own movements from visual information. I have revealed characteristics of self-motion perception from visual motion information by conducting psychophysical experiments. Based on the collected data, I modeled information processing of visual motion in self-motion perception. I am also studying visual illusion called motion contrast /motion assimilation; when a physically static stimulus surrounded by moving stimuli appears to move in the direction opposite to that of the surround motion, it is called motion contrast. When the center appears to move in the same direction, it is called motion assimilation. I discovered the conditions for motion contrast and motion assimilation. Furthermore, I found and reported new facts about perception of visual art and the dazzling feeling by glare. I also examined impressions of colors and personality structure, and perceptual dimensions of visual material perception using statistical techniques for signal processing. I also showed that origami (paper folding) proficiency is related to high spatial ability and introversion.
