Force Feedback in Virtual and Shared Environments 4 P. Buttolo J. Hewitt R. Oboe B. Hannaford Proceedings, IEEE International Conference on System, Man and Cybernetics, Vancouver BC, October 1995 1995 IEEE http://brl.ee.washington.edu/BRL/publications/Rep100.pdf We will present a demonstration allowing people to touch virtual objects and perform elementary manipulations, with visual and haptic feedback. The virtual environment consists of collision detection and dynamics software modules, a simple graphics representation, plus the kinematics and dynamics interface necessary to drive the force display. We will also present a force-feedback virtual squash, with two or more players located in Seattle and Padova (Italy). The game is an example of how to implement force feedback in a shared environment. The reproduction of a faithful and stable force signal to the operator requires the computation of forces with low latency and high. [POSTER].
