Reconstitution of facts using the modeled place because the real no longer exists.
The term « virtual reality » (or immersive multimedia or computer simulated reality) refers to a computer technology that simulates the physical presence of a user in an artificially generated software environment.
It creates a real or imaginary environment in which the user can interact. It can explore an environment, manipulate objects or perform a series of actions in a virtual world.
The purpose of virtual reality is to conduct a sensorimotor and cognitive activity in a digitally created world, which can be « imaginary, symbolic or a simulation of certain aspects of the real world » (extract from the Virtual Reality Treatise, P. Fuchs)
Virtual reality is not to be confused with augmented reality, which adds virtual elements in a real environment whereas virtual reality virtually creates a real or imaginary environment.
