Virtual reality (VR) is a technology which allows a user to interact with a computer-simulated environment. Most virtual reality environments are primarily visual experiences, displayed either on a computer screen or through special stereoscopic displays, but some simulations include additional sensory information, such as sound through speakers or headphones. Some advanced and experimental systems have included limited tactile information, known as force feedback. Users can interact with a virtual environment either through the use of standard input devices such as a keyboard and mouse, or through multimodal devices such as a wired glove, the Polhemus boom arm, and/or omnidirectional treadmill. The simulated environment can be similar to the real world, for example, simulations for pilot or combat training, or it can differ significantly from reality, as in VR games. In practice, it is currently very difficult to create a high-fidelity virtual reality experience, due largely to technical limitations on processing power, image resolution and communication bandwidth. However, those limitations are expected to eventually be overcome as processor, imaging and data communication technologies become more powerful and cost-effective over time.

Terminology

The origin of the term virtual reality is uncertain. It has been credited to The Judas Mandala, a 1982 novel by Damien Broderick where the context of use is somewhat different from that defined above. The VR developer Jaron Lanier claims that he coined the term http://www.jaronlanier.com/general.html. A related term coined by Myron Krueger, "artificial reality", has been in use since the 1970s. The concept of virtual reality was popularized in mass media by movies such as The Lawnmower Man (and others mentioned below), and the VR research boom of the 1990s was motivated in part by the non-fiction book Virtual Reality by Howard Rheingold. The book served to demystify the heretofore niche area, making it more accessible to less technical researchers and enthusiasts, with an impact similar to what his book The Virtual Community had on virtual community research lines closely related to VR.
