Virtual Reality: Today and Beyond Virtual reality (VR) is the creation of a highly interactive computer based multimedia environment in which the user becomes a participant with the computer in what is known as a "synthetic environment." Virtual reality uses computers to immerse one inside a three-dimensional program rather than simulate it in two-dimensions on a monitor (Lewis 14). Utilizing the concept of virtual reality, the computer engineer integrates video technology, high resolution image-processing, and sensor technology into the data processor so that a person can enter into and react with three-dimensional spaces generated by computer graphics.
