Mental processes involved in making preference judgments

How does the gaze behaviors and the sampling behaviors interact with preference judgments?

Visuo-motor transformation in arm reaching movements

How does the brain create an arm reaching motion towards an object?
1. What kind of coordinates is used for recognizing a spatial position?
2. How does the brain plan the arm reaching movements?
3. How does the brain activate muscles?
We have investigated them from the point of view of Robotics in ways of psychophysics experiments and non-invasive brain measurement by fNIRS.

Force display by the use of constrictive pressure on limbs

This study investigates a force display by the use of constrictive pressure on limbs. Force display systems in markets display a force using a robot. In contrast, the proposed force display displays a force using an illusion provided by the constrictive pressure on the limbs. The system is more lightweight than the conventional force display systems, and it can provide better safety. Applying a constrictive pressure on the distal part of a forearm provides a feeling of adding a force to an object by hand, such as pushing an object or holding an object. Applying a constrictive pressure on a thigh and lower thigh and lifting the feet up and down to coincide with the arm swings provide a feel of walking while sitting in a chair. A virtual diving underwater system has been developed using this technology.
