Virtual reality or virtual realities ( VR), also known as immersive multimedia or computer-simulated reality, is a computer technology that replicates an environment, real or imagined, and simulates a user's physical presence and environment in a way that allows the user to interact with it. Virtual realities artificially create sensory experience, which can include sight, touch, hearing, and smell.
Virtual realities are displayed either on a computer screen or with a special
virtual reality headset (also called head mounted display), and some simulations include additional sensory information and focus on real sound through speakers or headphones targeted towards VR users.
Different companies such as Oculus, HTC, Samsung e.t.C have come up with different VR headsets.

For the uninitiated, virtual reality is an immersive experience in which your head movements are tracked in a three-dimensional world, making it ideally suited to games and even movies.
While VR was a non-starter back in the 90s, developers are now creating mind-blowing experiences that look set to revolutionise gaming and entertainment.
