Force display system of virtual objects using haptic interface

Multimedia services such as audio and visual media have been advanced rapidly. In addition to them, physical force information is expected as the next multimedia service. As for these services, haptic interface is the most promising service as the force display system. Although the haptic interface has been studied vigorously, many researches are only concentrating on its mechanism and control system, which means that these researches are not studied systematically. This paper describes the overall force display procedure using the haptic interface in order to grasp this problem systematically. This paper shows a composition of hardware system, control methods, geometrical models of the virtual object, evaluation of force feeling, and manipulation of the virtual object.
