Keynote Address 2: Available Virtual Reality Techniques Now and in the Near Future

Abstract : This paper presents available virtual reality techology as well as techology that is projected to become available to NATO in the near future. Areas discussed are new PC technology (graphies rendering and wearable computers) personal and large-volume displays large volume tracking force feedback interfaces and software toolkits. PCs presently render millions of polygons sec. Their reduced cost makes possible the distribution of vitural environments at many sites and in many countries. Large-volume displays are more expensive but allow more natural user interactions. They do require large-volume tracking ffiat is fast and accurate. Haptic interfaces are a recent class of input/output devices that increase simulation realism by adding the sense of touch. This comes at a cost of more computing power and better physical modeling. The modeling and programming needs of virtual reality are met by software toolkits designed for such simulations.
