what mean by virtual reality?

Answer 1

Virtual reality is an artificial environment created with computer hardware and software and presented to the user in such a way that it appears and feels like a real environment. To "enter" a virtual reality, a user dons special gloves, earphones, and goggles, all of which receive their input from the computer system. In this way, at least three of the five senses are controlled by the computer. 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.

To date, virtual reality systems require extremely expensive hardware and software and are confined mostly to research laboratories.

The term virtual reality is sometimes used more generally to refer to any virtual world represented in a computer, even if it's just a text-based or graphical representation.

Answer 4

Virtual means 'nearly' or 'in lieu of' or 'being almost the same as', therefore virtual reality means, being almost the same as reality. When applied to a computer or program generated visual it means that the visual experience is nearly the same as reality. For example: a flight simulator in which one experiences the view as if flying in an aircraft - the experience is nearly identical to actually flying in an aircraft.
