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.
The use of technology has been continuously increasing and so is its impact on the people present. Same with it the demand of virtual reality has also been increased with time and its outcomes cannot be compared with the normal technology. Augmented reality also shares some important characteristics and elements of virtual reality as these both have some similarities in common between them. With the help of this technology, a user is able to have a completely clear view of all the surroundings that have been present. Everything in this process is a proof of gradual increase in technology as well as in its use when it comes to a common man. Everything connected with the need of a user is customized in it further to that various plans are made and required outcomes are achieved in a fixed span of time.
