"To begin with, Virtual Reality is a part of computer science and it represents a new approach to computer science. Instead of treating the computer as a box that's out there that is supposed to accomplish something, you put a human being in the center and say, "Let's look at the human being closely. Let's see how people perceive the world or how they act. Let's design a computer to fit very closely around them, like a glove, you might say. Let's match up the technology to exactly what people are good at.""
