VR is a new audio-visual communication medium whose mission is to sell the idea of entering a computer-generated, three-dimensional environment where the experience is so immersive it tricks our brain into believing this virtual world is actually reality. Its ultimate goal is to allow us to experience sensations that we could never undergo in our daily lives otherwise. Things like getting out of our bodies and seeing ourselves from the outside, or being tele-transported to real and fictional places are now becoming possible with this new medium.
