 * VIRTUAL REALITY**

Is a technology, which allows a user to interact with a computer stimulated environment, be it a real or imagined one. Most current virtual reality environments are primarily visual experiences, displayed either on a computer screen or through special or stereoscopic displays but some simulations include additional sensory information, such as sound through speakers or headphones. Some advanced, haptic systems now include tactile information, generally known as force feedback, in medical and gaming applications.

Users can interact with a virtual environment or a virtual effect (VA) either through the use of standard input devices such as a keyboard and mouse, or through multidominal devices such as a [|wired glove]. 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.
