The effect of spatial resolution is still not clear in haptic rendering. This sketch reveals it by measuring absolute thresholds for surface smoothness using two point-contact haptic displays of different resolutions.


The Development of the Virtual Human Abdomen: Algorithms and Methodologies

On-going research on a mobile telecommunication system in which users can mutually transmit their ambient information and can feel mentally closer to each other.


Hand-Held Torque Feedback Device

Unlike conventional force displays, which have some bases supporting reaction force, this proposed torque display requires no base, because it uses the angular momentum transition caused by controlled currents of three orthogonal motors.
