Definition of Virtual Reality

Virtual reality is an expression that refers to devices that make it possible to digitally simulate an environment by a machine (computer). Depending on the technologies used, it allows the user to feel a virtual universe with different senses: touch, hearing, smell at the most common sight.

Virtual reality therefore allows a person to experience immersion and perform sensory-motor activity in the artificial world. To ensure full immersion, the user uses the virtual reality headset. This uses the principle of stereoscopic 3D display to place the viewer in a virtual world created by a machine.
