what is the meaning of virtual reality?????

Question

it is related to computer.and more over i want a detailed answer for this question....................

Answer 1

The real-looking computer screens shown for computer games and flight simulators.

They look real and respond in a realistic way as you "walk" through virtual "reality."

The definition is that simple. The PROGRAMMING for a good, realistic virtual environment is very complex and requires a lot of core memory to run, though.

Answer 2

Here are multiple definitions of Virtual Reality

An artificial environment created with computer hardware and software. To "enter" a virtual reality, a user wears special gloves, earphones, goggles and/or full-body wiring. In addition to feeding sensory input to the user, the devices also monitor the user's actions. The goggles, for example, track how the eyes move and respond accordingly by sending new video input.

A computer simulation of a real 3-dimensional world, often supplemented by sound effects. People often associate virtual reality with a body suit and head gear that inclues an internal screen. The suit measures your boby's movements and displays them on the screen. These computerized images can be simulated in any environment making you feel like you're realy there. This is one interface, a more common use for VR is seen in many 3D computer games.

The proposed construction of artificial realities in a purely digital realm; not yet technically feasible in the strictest sense. By extension any form of simulated reality - textual or graphical - created using computers. Also used as a marketing term to sell technology that can create two-dimensional representations of three-dimensional space on a computer screen.

A computer-based technology for simulating visual auditory, and other sensory aspects of complex environments.

A human-computer interface in which the computer creates a sensory-immersing environment that interactively responds to and is controlled by the behavior of the user.

an immersive and interactive simulation of either reality-based or imaginary images and scenes. See Cyberspace.

Virtual reality (often called VR for short) is generally speaking an attempt to provide more natural, human interfaces to software. It can be as simple as a pseudo 3D interface or as elaborate as an isolated room in which the computer can control the user's senses of vision, hearing, and even smell and touch.

simulated environments and the methods used to create them

Immersion of one or more individuals in a virtual environment, with the aim of achieving the illusion that they are in a place, time, or situation different from their actual real-world location and/or time.

A technology that is computer generated and allows the user to interact with data that gives the appearance of a three-dimensional environment. The user can "enter" and "navigate" the "3-D world" portrayed as graphic images and change viewpoint and interact with object in that world as if "inside" that world.

An interactive, simulated environment (three dimensional multimedia application) that allows the users to perform actions that give them more control over how the information is viewed. Being a medium for education, it allows an individual to project him or herself into a computer generated world and move freely within it. ...

Answer 3

It means that this computer simulation is VIRTUALLY (almost) reality.
