Force flow between human and object in virtual world

In this paper we propose a dynamic force simulator (DFS) for force feedback in human-machine systems. The DFS simulates object dynamics, contact model and friction characteristics of the human hand interacting with objects in a virtual reality and aims at the human skill acquisition as a first step of the previously proposed intelligent assisting system (IAS). After derivation of the kinematic and force relations between hand and object space we propose a method of realizing desired feedback forces to the human operator. Interaction with the DFS allows the calculation and feedback of appropriate forces to the force controlled actuators of the sensor glove we have developed.<<ETX>>
