Abstract

A system and method are disclosed in which in a conventional non-grounding man-machine interface having no reaction base on the human body and for giving the existence of a virtual object and the impact force of a collision to a person, a haptic sensation of a torque, a force and the like can be continuously presented in the same direction, which cannot be presented by only the physical characteristic of a haptic sensation presentation device. In a haptic presentation device, the rotation velocity of at least one rotator in the haptic presentation device is controlled by a control device, and a vibration, a force or a torque as the physical characteristic is controlled, so that the user is made to conceive various haptic information of the vibration, force, torque or the like.
