It is a form of computer simulation in which the participant has the feeling that he is in an artificial environment (virtual reality). You are a participant environment looks through two tiny television screens (one for each eye) built into the viewfinder. The sensors detect the movements of the participant's head or body, which causes a change in the apparent viewing position. The participant may wear data gloves (datagloves) or two controllers. These are gloves equipped with sensors that allow the user to seemingly pick up and move objects in a simulated environment.
