Paper Abstract

This paper describes an approach to synthetic three-dimensional object manipulation using three different haptic I/O devices in a virtual workspace on a graphics superworkstation. The devices involve the operator in unique mode8 of interaction that require positioning a six degree-of-freedom sensor, applying torques to a static ball, or creating interpreted hand ge8tures. With these devices, the user can select, rotate and deposit synthetic virtual objects in the micro world. The micro world is an "artificial reality" in which elementary physical forces of gravity, volume preservation, collision, and external user input may be applied. The techniques developed overcome some of the difficulties experienced with two-dimensional input devices in a three-dimensional space. Furthermore, the ability of the user to continuous modify physical constraints while observing the results in real-time facilitates data interpretation tasks.
