Virtual reality is the use of computing to create simulated environments. Virtual reality places the user in a three-dimensional experience. Instead of looking at the screen in front of them, users are immersed in and interacting with 3D worlds. Simulating the human senses - all five - turns a computer into a vehicle into new worlds. The only limit to the excellent VR experience is computing power and content availability.

All three types of VR, from non-immersion, semi-immersion, fully immersion or mixtures thereof, are also referred to as extended reality (XR). Three types of virtual reality experiences provide different levels of computer-generated simulation.

Non-immersive virtual reality

This category is often overlooked as VR simply because it is so common. VR-intensive technology includes a computer-generated virtual environment in which the user is simultaneously aware of and controlled by their physical environment. Video games are a prime example of non-immersive VR.

Semi-immersive virtual reality

This type of VR provides an experience based in part on a virtual environment. This type of VR makes sense for educational and training purposes with graphics computers and large projector systems such as flight simulators for pilots.

Fully immersive virtual reality

There are currently no fully immersive VR technologies, but progress is so rapid that they may be just around the corner. This type of VR creates the most realistic simulation experience, from sight through sound to sometimes olfactory sensations. Car racing games are an example of immersive virtual reality that gives the user a sense of speed and driving skills. VR, developed for gaming and other entertainment purposes, is on the rise in other sectors.

The definition of virtual technology includes specific shared characteristics. Not only are they immersive, but they are also computer-generated, credible as multidimensional experiences and interactive.
