Virtual Reality

Virtual Reality (VR) is an expanding trend in Computer Science. Nowhere else except within this "parallel universe" is one able to assert complete control over his environment without fear of personal harm. Within the realm of a Virtual Environment (VE), an individual is able to interact with functioning surroundings and accomplish tasks otherwise impossible or engage in activities otherwise unaccessible. The VR field is rapidly growing, calling the attention of many scientists as well as artists. Much literature on the internet has been written on the subject including University of Idaho's description of the terms and technologies used in VR and an extensive Encyclopedia of Virtual Environments (Eve) describing VR and its applications, posted by the University of Maryland.

Technology

One of the goals of VR is to create an environment as similar as possible to the reality in which humans live. In order to achieve this, special attention must be paid to minute details as well as overall concepts. The Computer Graphics Lab (LIG) at the Swiss Federal Institute of Technology (EPFL) in Lausanne has placed papers on the web describing their research in simulating the nuances of human activity. Included among their subjects are the movements involved in walking and grabbing objects, as well as deformities which will enable the creation of characters with a more human physique. In addition, research on the development of autonomous actors will enhance the effects of the VE.

Similarly, the inanimate aspects of a VE are equally as important. Stanford University has posted a paper addressing the issue of design within spatial parameters. Other issues of an environment need to be explored, such as running two dimensional applications in a three dimensional environment. The technology is ever expanding.

Applications

VR is capable of affecting several facets of life. In addition to use as a game format, as evidenced by Silicon Graphics and Nintendo, the technology has promising uses in entertainment, education, and industry. Both San Diego University Art Gallery and the Banff Centre for the Arts are incorporating virtual art into their displays. VR has also been suggested in the treatment of phobias, as well as an aid to technical fields. Similarly, the medical field is researching the possibilities of VR aiding in diagnosing and referencing medical problems as well as treatment for individuals with disabilities.

The military also has an interest in the applications of VR assisting in training and combat simulation. NASA, on the other hand, is proposing VR will have a beneficial use for applications in astrophysics. In computer science, a VE has been proposed as the perfect host for a Turing Test.
