Physics-based Approach to Haptic Display Brown, J. Michael and Colgate, J. Edward ISMRC 1994, Houston, TX This paper addresses the implementation of complex multiple degree of freedom virtual environments for haptic display. We suggest that a physics-based approach to rigid body simulation is appropriate for hand tool simulation, but that currently available simulation techniques are not sufficient to guarantee successful implementation. We discuss the desirable features of a VE simulation, specifically highlighting the importance of stability guarantees.
