with a piece of machinery known as the computer. This is done with several computer-user interfaces used to simulate the senses. Among these, are stereoscopic glasses to make the simulated world look real, a 3D auditory display to give depth to sound, sensor lined gloves to simulate tactile feedback, and head-trackers to follow the orientation of the head.
Since the technology is fairly young, these interfaces have not been perfected, making for a somewhat cartoonish simulated reality. Stereoscopic vision is probably the most important feature of VR because in real life, people rely mainly on vision to get places and do things. The eyes are approximately 6.5 centimeters apart, and allow you to have a full-colour, three-dimensional view of the world. Stereoscopy, in itself, is not a very new idea, but the new twist is trying to generate completely new images in real- time. In 1933, Sir Charles Wheatstone invented the first stereoscope with the same basic principle being ...

users the proper stereo images when moving their heads well when a head- motion sensor is used to adjust the effect. Sound is another important part of daily life, and thus must be simulated well in order to create artificial reality. Many scientists including Dr. Elizabeth Wenzel, a researcher at NASA, are convinced the 3D audio will be useful for scientific visualization and space applications in the ways the 3D video is somewhat limited. She has come up with an interesting use for virtual sound that would allow an astronaut to hear the state of their oxygen, or have an acoustical beacon that directs one to a trouble spot on a satellite. The "Convolvotron" is one such device that ...
