Text 21 A. VIRTUAL REALITY

One of the most exciting new areas of computer research is virtual reality. Having been featured in TV sitcoms as well as public televi­sion documentaries, virtual reality is merely an ambitious new style of computer interface. Virtual reality creates the illusion of being in an artificial world — one created by computers.

Virtual reality visitors strap on a set of “eyephones”, 3-D goggles that are really individual computer screens for the eyes. Slip­ping on the rest of the gear allows you not only to see and hear, but also to sense your voyage. The world of virtual reality has been called cyberspace, a computer-enhanced fantasy world in which you move around and manipulate objects to your mind’s content.

When you move your head, magnetic sensors instruct the comput­er to refocus your eye phones to your new viewpoint. Sounds surround you, and a fiber-optic glove allows you to “manipulate” what you see. You may seek out strange new worlds, fight monsters in computer combat, or strap yourself into the seat of a Star Wars-type jet and scream through cyberspace, blasting all comers to oblivion (computer oblivion, at least). Or, with your stomach appropriately settled, you might even try out the most incredible roller coaster ride you will ever take in your life.

For the disabled, virtual reality promises a new form of freedom. Consider the wheelchair bound paraplegic child who is suddenly able to use virtual reality gear to take part in games like baseball or basketball. Research funded by the government takes a military point of view, investigating the possibility of sending robots into the real conflict while human beings don cyberspace gear to guide them from back in the lab.
