Virtual reality (VR) typically refers to computer technologies that use software to generate realistic images, sounds and other sensations that replicate a real environment (or create an imaginary setting), and simulate a user’s physical presence in this environment, by enabling the user to interact with this space and any objects depicted therein using specialized display screens or projectors and other devices. VR has been defined as “…a realistic and immersive simulation of a three-dimensional environment, created using interactive software and hardware, and experienced or controlled by movement of the body” or as an “immersive, interactive experience generated by a computer”. A person using virtual reality equipment is typically able to “look around” the artificial world, move about in it and interact with features or items that are depicted on a screen or in goggles.
