Virtual reality is a kind of simulation in which the subject feels immersed in a real scene. It is a computer technology that simulates the physical presence of a user in an artificial environment controlled by software. The user is thus immersed in a controlled and interactive reality, on which he can act. Several ways of interaction are then possible, ranging from joystick control to complex sensory experiences.

Virtual Reality and Augmented reality
It is important to distinguish virtual reality from augmented reality. The principle of the latter is based on the superposition to the “real” reality of various digital information. This real-time addition of information makes it possible to inform the user on a certain number of aspects related to what he observes. This is particularly the case with the fighter pilots and their head-up display device (HUD). Thanks to this transparent screen placed at head height, the pilot has a real-time view of the tactical situation. This allows him to remain alert to what is happening outside his cockpit, without giving up control of vital flight parameters. Visit this site for vr company.
Some virtual reality interfaces
-The sensory interfaces (visual, sound, tactile, olfactory) make it possible to feel the virtual world and to dive into it. Interaction becomes possible, thanks to body location sensors and manual motor interfaces. Several sensory interfaces have been designed, including:
-The Immersive Room which is cubic or spherical and consists of projection screens. The user is then immersed in a geometrically coherent environment in which the perspective is recalculated in real time;
-The stereoscopic screen equipped with a device for tracking the observer’s head. A virtual scene is then displayed in stereoscopic vision, and the images are recalculated in real time according to the position of the eyes of the observer;
-The Data Glove which has sensors and allows the user to enter a virtual object. It works through real-time scanning of hand movements and offers a very real realism.
-Visiocasques which are portable systems that provides the location of the user’s head and the simulation of the visual system. They profoundly enhance the fun video experience with total 360 ° immersion.
Virtual reality helmets
In order to ensure the user is as fully immersed as possible, the user must use a virtual reality headset. This is a technology whose development began in the 1950s, and which has a new age recently. The virtual reality headset, also called visiocasque, is a display device that allows a sensory experience in a digital world. Still called VR headset, it is equipped with stereoscopic screens positioned on the focal plane of the lenses and a pair of headphones. The stereoscopic display allows the user to perceive the distance of nearby objects and thus simulates terrain and depth.
