virtual reality         
¦ noun the computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by using special electronic equipment.

N-UNCOUNT
virtual reality         
(VR) 1. <application> Computer simulations that use 3D graphics and devices such as the data glove to allow the user to interact with the simulation. 2. <games> A form of network interaction incorporating aspects of role-playing games, interactive theater, improvisational comedy, and "true confessions" magazines. In a virtual reality forum (such as Usenet's news:alt.callahans newsgroup or the MUD experiments on Internet and elsewhere), interaction between the participants is written like a shared novel complete with scenery, "foreground characters" that may be personae utterly unlike the people who write them, and common "background characters" manipulable by all parties. The one iron law is that you may not write irreversible changes to a character without the consent of the person who "owns" it, otherwise, anything goes. See bamf, cyberspace.

Virtual reality

Virtual reality (VR) is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business (such as virtual meetings). Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR, although definitions are currently changing due to the nascence of the industry.

Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate some realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets consisting of a head-mounted display with a small screen in front of the eyes, but can also be created through specially designed rooms with multiple large screens. Virtual reality typically incorporates auditory and video feedback, but may also allow other types of sensory and force feedback through haptic technology.
