techniques for scientific visualization, of which the virtual wind tunnel is the main focus. He began work in the virtual reality field in 1984 at VPL Research, working on a graphics-based programming environment using the prototype DataGlove for input; later he was involved in work on the DataGlove model II. He joined the VIEW lab at the NASA-Ames Research Center in 1987, where he was involved in integrating the various input-output and graphics systems into a virtual environment. This included research in software architectures for virtual reality systems and human factors. In 1991, he was cochair of the IEEE Symposium on Research Frontiers in Virtual Reality and is program cochair of the IEEE Virtual Reality Annual International Symposium.
