We aim to understand scientifically how we perceive the world/environment and communicate with others. Embodied perception is a main perspective in our research. Our perceptual process and communication are crucially connected to our body physically and psychologically. We are investigating three research themes based on this perspective.
- Science for Mobile Observers
- Science for Embodied Reality
- Science for Implicit Social Cognition
Human body and our body scheme are changing with virtual reality technology and robotics. We investigate how our mind, behavior and societal issues change by modifed and new bodies in the real or virtual world. It contributes to designing the future society.
Theme1：Science for Mobile Observer
To understand perception for mobile observers, we are investigating self-motion perception, 3-D perception, scene and human-body recognition across viewpoints with psychophysical experiments. To know interaction of perception and action, we are measuring motor behavior and perception during action such as walking and driving a car. Parts of driving study are cooperative studies with motor companies. We are developing a system to experience tele-presence of walking using virtual reality.

Theme2：Science for Embodied Reality
To know what is realty, we are focusing on body perception, body ownership, and self-agency. Perceptual reality must be based on our body and its perception. We are investigating material perception, perceptual aesthetics, lightness perception, self-motion perception, human-body perception, and augmented human in virtual-reality environments. Cross-modal studies such as vision-vestibular interaction on postural control and face-voice interaction on emotions are included in the theme. We are modifying human body appearance and function using virtual reality to see how human mind and behavior change in such modified bodies.

Theme3：Science for Implicit Social Cognition
We interact with others naturally, and perceive the world and others based on social communications. The crucial factor for implicit social cognition is our body. We are investigating body perception, neurophysiology of empathy, equity, and moral. We found that the preverbal infants show sympathy for others in distress and that humans can empathize with humanoid robots. We focued on social interactions not only in the real world but also in the rapidly spreading metaverse.
