Robert W. Lindeman, The George Washington University

In this talk, I present an overview of technology and techniques used to stimulate the human senses in virtual reality applications. The visual and audio channels have received by far the most attention by researchers, to the point that we can now produce synthetic visual and audio experiences that are (arguably) indistinguishable from reality. Effective stimulation of the smell and taste senses have been more elusive, partially because of the intrusive nature of the stimulation, and partly because of a general lack of understanding of the composition of the stimuli. Touch has received a significant amount of attention from researchers, with the main impediments to widespread use being device weight and power requirements, as well as the number of cumber present in general solutions. I present work we have been doing to provide wearable, untethered, full-body haptic feedback systems, as well as a software framework for integrating visual, audio, and haptic rendering into a single system.
