Virtual reality is the most immersive type of reality technology which creates an artificial environment to inhabit. This immersive, computer-generated environment blocks out the sensory input from the outside world; and uses the visual and auditory cues to make the virtual world seem quite real. It is immersive because of its simulated setting that manages to trick your unconscious mind to start treating this illusion as real.

But how is this achieved? What do you need to experience this simulated environment? To enter the world of Virtual Reality, you must first wear an HMD headset (Head Mounted Display). The headset is the display for viewing the virtual environment. With the headset ON, a virtual world appears in every direction you cast your gaze.
