Is Virtual Reality Virtually Here?

A typical virtual-reality system (VR) is composed of a headset with goggles, onto which a 3-dimensional computer-generated world is projected, and a hand instrument that serves as both a gun and a forward-motion device. VR may become an alternative for training by the end of this century as a result of its development for leisure-time activities. Some of the ways VR might be most productively used include: 1. when training mistakes would be costly, 2. when the necessary environment cannot be experienced in the real world, and 3. to build interfaces that are sensible and can be manipulated. The omnipresence of VR off the job will create a demand for the use of VR in job training and in work processes themselves. As a result, people may use VR in situations in which it is neither appropriate nor cost-effective. VR will become a powerful technology and those people who work with it will, in a very real sense, be co-discoverers of a new world.
