We will then go into how people with disabilities currently make use of a variety of assistive technologies and how virtual reality might be helpful to this population. As the first speaker, I get to set the stage by giving you my definition of virtual reality. What you'll find over the next two days is that most of the other speakers will provide their definition as well. The definitions may be different. This is a young field and we are still finding our way.
Virtual reality is a computer-generated technology.
The computer is critical. It requires 3-D models of what we call virtual worlds. By a 3-D model, we mean a computer model or a computer drawing of an object that includes its characteristics such as weight, color, density and so on. In addition, virtual reality is interactive. I want to review applications of virtual reality that are available now.
