Virtual Reality is the way to create a 3-D computer-generated environment that immerses the user into a virtual world. You could put on a pair of VR goggles and it takes us to a simulated set-up making us completely oblivious from our actual surroundings. Current VR technology immerses the user in a computer-generated environment that simulates reality through the use of interactive devices, which send and receive information and are worn as goggles, headsets, gloves, or body suits. This technology includes multi-projected environments, sometimes in combination with physical environments or props, to generate realistic images, sounds and other sensations that simulate a user’s physical presence in a virtual or imaginary 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. Everything that we know about our reality comes by way of our senses. In other words, our entire experience of reality is simply a combination of sensory information and our brains sense-making mechanisms for that information. It stands to reason then, that if you can present your senses with made-up information, your perception of reality would also change in response to it. You would be presented with a version of reality that isn’t really there, but from your perspective it would be perceived as real. Something we would refer to as a virtual reality. A key part of Virtual Reality is creating the reality. One component of virtual reality is the frame rate which is the rate at which the Graphics Processing Unit can process images per second. You also would need a minimum 100-degree field of view. We need the response to be less than 20 milliseconds to trick the brain which is achieved by combining all the above factors in the right proportion.
