Virtual Reality

Virtual reality (VR) is the use of a computer to create a simulated environment that appears and feels like a real environment and allows users to explore a space and manipulate the environment. In its simplest form, a VR application displays what appears to be a three-dimensional view of a place or object, such as a landscape, building, molecule, or red blood cell, which users can explore. For example, architects can use VR software to show clients how a building will look after construction or remodeling project.

In more advanced forms, VR software requires that users to wear specialized headgear, body suits, and gloves to enhance the experience of the simulated environment (Vance and Reed 34-58). The headgear displays the simulated environment in front of a userÐŽ¦s eyes. The body suit and gloves sense motion and direction, allowing a user to move through, pick up, or hold items displayed in the virtual environment. Experts predict that in time the body suits will provide tactile feedback so users can experience the touch and feel of the virtual world.

Many games, such as flight simulators, use virtual reality. In these games, special visors allow users to see the computer-generated environment. As the user walks around the games electronic landscape, sensors in the surrounding game machine record movements and change the view of the landscape accordingly.

Companies increasingly are using VR for more practical commercial applications, as well. Automobile dealers, for example, use virtual showrooms in which customers can view the exterior and interior of available vehicles. Airplane manufacturers use virtual prototypes to test new models and shorten product design time. Many firms use personal computer-based VR applications for employee training (Shelly Cashman Series„µ Microsoft Word 2000 Project 2). As computing power and the use of the Web increase, practical applications of VR continue to emerge in education, business, and entertainment.
