Virtual Reality Virtual reality (VR) is the use of computers to simulate a real or imagined
environment that appears as a three-dimensional (3-D) space. VR involves the display of 3-D
images that users explore and manipulate interactively.
Using special VR software, a Web developer creates an entire 3-D environment that contains infinite space and depth, called a VR world. A VR world, for example, might show a house for
sale. Potential buyers walk through rooms in the VR house by moving an input device forward,
backward, or to the side.
