Virtual reality places the user inside a three-dimensional experience. Instead of viewing a screen in front of them, users are immersed in and interact with 3D worlds. Simulation of human senses—all five of them—transforms a computer into a vehicle into new worlds. The only limitation to a superb VR experience is computing power and content availability.
