"Virtual reality (in English, virtual reality or VR) is a technology that allows you to immerse a person in an artificial world created digitally. It should not be confused with augmented reality (see in this regard our file on augmented reality and its applications).
It can be a reproduction of the real world or a totally imaginary universe. The experience is both visual, auditory and, in some cases, haptic with the production of feedback. When the person is equipped with the appropriate interfaces, such as gloves or clothing, he may then experience certain sensations related to touch or certain actions (blow, impact ...). "
