Virtual Reality (VR)
is the use of computer technology to create a simulated environment. Unlike traditional user interfaces, VR places
the user inside an experience. Instead of viewing a screen in front of them, users are immersed and able to interact with 3D worlds
. By simulating as many senses as possible, such as vision, hearing, touch, even smell, the computer is transformed into a gatekeeper to this artificial world. The only limits to near-real VR experiences
are the availability of content and cheap computing power.
