Ever heard of VR (Virtual Reality)?
Virtual reality means creating immersive, computer-generated environments that are so convincing users will react the same way they would in real life. The idea is to block out the sensory input from the outside and use the visual and auditory cues to make the virtual world seem more real. While the concept is simple, actually building virtual reality systems has proven difficult to do, until recently.
“The big difference here is the sensory deprivation, you’re more susceptible to real life-like experience — on a very primitive level you’re tuning everything out.”
