Brief summary of Artificial Reality/Tele-Existence Symposium, July 1991, Tokyo Japan. I did not attend this conference. All papers but the keynote were presented by researchers from the US. A panel was evenly divided 3-3. There was a vendor exhibition of two US products and three Japanese, including "Vision System for Tele-existence" (Yaskawa Electric), and "Virtuality 1000SU with Touch Glove" (Nissho IWAI). It was also reported that Matsushita will use VR equipment next month to assist customers in kitchen design, but that the equipment was developed by VPL from California. It is difficult to know how to judge this field. As far as I can tell from reading the papers, many potential applications are hoped for in industrial applications, but at the moment most of these are speculative, or at best in prototype form. There are a number of small commercial US start-ups, while Japanese work is either at the universities or within large corporate laboratories. Naturally the first "applications" are to expensive video games. Hardware will have to get cheaper and much faster to support synchronization with human-hand-head-eye movements. The most interesting scientific paper was from Bryson (NASA) concerning applications to visualizing fluid simulations. This is a viable system, but also one of the more natural and hence conservative applications. The Japanese are very interested in robotics related aspects. For example, Tachi discussed various possibilities of a master-slave system with a visual and auditory sensation of presence, computer control system and an anthropomorphic slave robot mechanism with an arm having seven degrees of freedom and a locomotion mechanism. Sato has been working on object manipulation in 3-D and vizualization of perceptual information flow. Hirose listed three projects focused on visualization at U Tokyo, a See-Through Helmet Mounted Display, Virtual Physical Space Simulator, and Virtual 3-D Visualization of Complicated Software. Iwata described two projects involving force-feedback, one a desk-top hand, and the second a walker. Although the titles of the papers may not emphasize it, the Japanese are extremely interested in the larger concepts of VR and view it as a way of changing time and space in industry by eliminating the time/space necessary to move between two locations.
