Virtual Reality

The computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment.

VR is an artificial environment that is created with software and presented to the user in such a way that the user accepts it as a real environment. Whereas augmented reality place virtual objects into a users view of the physical environment, virtual reality replaces the users view of the physical environment with a virtual environment, in which virtual content resides.
