Research Activities

We aim to reveal the mechanism of the visual information processing in the Eye-Brain system. The researches in Uchikawa lab cover color vision, color perception, visual functions in the peripheral visual field, attention, eye movement and visual space perception. In addition we try to apply our knowledge of visual functions to the real world in order to realize a human machine interface (HMI), which is easy, safe and pleasant for humans.
