What is virtual reality?

  • (noun): A hypothetical three-dimensional visual world created by a computer; user wears special goggles and fiber optic gloves etc., and can enter and move about in this world and interact with objects as if inside it.

Virtual Reality

Virtual reality (VR) is a term that applies to computer-simulated environments that can simulate physical presence in places in the real world, as well as in imaginary worlds. Most current 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, haptic systems now include tactile information, generally known as force feedback, in medical and gaming applications. Furthermore, virtual reality covers remote communication environments which provide virtual presence of users with the concepts of telepresence and telexistence or a virtual artifact (VA) 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, and omnidirectional treadmills. The simulated environment can be similar to the real world in order to create a lifelike experience—for example, in simulations for pilot or combat training—or it can differ significantly from reality, such 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, the technology's proponents hope that such limitations will be overcome as processor, imaging, and data communication technologies become more powerful and cost-effective over time.

Famous quotes containing the words reality and/or virtual:

    She’s in the house.
    She’s at turn after turn.
    She’s behind me.
    She’s in front of me.
    She’s in my bed.
    She’s on path after path,
    and I’m weak from want of her.
    O heart,
    there is no reality for me
    other than she she
    she she she she
    in the whole of the reeling world.
    And philosophers talk about Oneness.
    Amaru (c. seventh century A.D.)

    Neither dead nor alive, the hostage is suspended by an incalculable outcome. It is not his destiny that awaits for him, nor his own death, but anonymous chance, which can only seem to him something absolutely arbitrary.... He is in a state of radical emergency, of virtual extermination.
    Jean Baudrillard (b. 1929)
