Outline of Final Research Achievements

In this study, a haptic rendering method named indirect haptic feedback is proposed.
The method separates motion input point and reaction force exerted point of a haptic interface. A prototype system, which consists of a motion tracker, a 2-DOF haptic interface that is equipped with a force sensor, and a visual display, is developed. The system measures the position of the fingertip of a user and produces an appropriate horizontal force on the thenar eminence of the user. Through the visio-haptic interface, a user can perceive the surfaces of 3D virtual objects. In addition, the user can perceive the frictional force on the surface of the objects. Through evaluation tests, it was verified that the subjects could effectively perceive the 3D virtual objects using this system. Moreover, it was suggested that visual dominance was observed when changing the elastic modulus of the visual model of the elastic virtual object by using our system
