Virtual reality is a simulated experience that can be similar to or completely different from the real world. Applications of virtual reality include entertainment, education and business. Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR.
One may distinguish between two types of VR; immersive VR and text-based network VR. The immersive VR changes your view, when you move your head. While both VRs are appropriate for training, Cyberspace is preferred for distance learning. In some cases these two types are even complementary to each other. This page mainly focuses on the immersive VR.
Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items.
