Virtual Reality is today the most known and used immersive technology. It allows its user to immerse oneself in a virtual environment recreated from scratch, thanks to a virtual reality headset. It is also possible to interact with this environment and to move around by means of joysticks.

Augmented Reality overlays in real-time virtual elements, usually recreated in 3D, on a real environment. This technology is used with a tablet, a smartphone or augmented reality glasses that give the illusion of a perfect integration of the virtual in the real.

Mixed Reality is a mixture of augmented reality and virtual reality. It allows an interaction between the virtual world and the real world thanks to a HoloLens headset. The user can then virtually interact with the virtual elements with gestures or joysticks.
