Abstract

Continuous advances in computer technology are making it possible to construct virtual environments with an ever-increasing sense of visual realism. What is lacking are interfaces that allow users to manipulate virtual objects in an intuitive manner. In this paper, we present a 7 DOF tension-based haptic interface that allows users to not only grip an object but also to sense an object's width. We have developed a system to utilize the physical action of gripping to display grasp manipulation in virtual environments. We also present a method to calculate the position and display force associated with this gripping mechanism. Finally, we show the validity of our proposed haptic interface through examples.
