Virtual reality or near reality generally refers to a certain kind of a reality emulation. Everything that is perceived by our senses forms a part of our reality. When you give your sense organs some made up or false information, the same is carried to your brain and you automatically react to the same. Virtual reality is a three- dimensional or 3D environment that is generated by a computer and, is explored by a person. The person starts feeling like a part of this environment. People can experience virtual reality with the help of specialised electronic equipment like HTC Vive and Ocuclus Rift.
