The views presented at that time were simple wire frame models. The advance of computer graphics knowledge and technology, itself tied to the enormous increase in processing power and decreas...

...orded by the virtual reality system. Psi is determined by the extent to which the system can produce events that directly relate to the participant, and the overall credibility of the scenario being depicted in comparison with expectations. We argue that when both PI and Psi occur, participants will respond realistically to the virtual reality. . Keywords: virtual reality, virtual environment, presence, telepresence, plausibility 1. INTRODUCTION The technology for Immersive Virtual Reality (IVR) has existed for 40 years initially as a demonstrated laboratory-based idea (The Ultimate Display) (Sutherland 1965), and for the past 20 years as practical, affordable and useful systems. The vast majority of research and development in this area has been to use it as a way to simulate physical reality. Yet it is a medium that has the potential to go far beyond anything that has been experienced before in terms of transcending the bounds of physical reality, through transforming your sense of place, and through non-invasive alterations of the sense of our own body. In other words, virtual reality has rarely been seen as a medium in its own right, as something that can create new forms of experience, but ra...
