virtual reality - Computer Definition
A computer-generated reality that projects the user into a 3D space. Using a stereoscopic headset that provides a completely immersive experience, the virtual reality (VR) system is operated by the user's head and hand movements or a physical control unit, the latter commonly used with virtual reality games. In the early days of VR, data gloves tethered by wires to a computer were used to track hand gestures. Training and Entertainment Flight simulators for pilot and astronaut training were the first form of virtual reality, which although extremely expensive, provide a very realistic simulation of the cockpit. Although 3D computer games add more depth and realism than their 2D equivalent, headset-based VR games are much more immersive than viewing a monitor. VR headsets are either entirely self-contained units or a device onto which the user's smartphone is attached (see Oculus Rift, Samsung Gear VR and Google Cardboard). Virtual Reality vs. Augmented Reality "Virtual" reality is an entirely generated environment, whereas "augmented" reality creates images or video in space in front of the user or off to the side (see augmented reality). See 3D visualization, virtual world, head mounted display, 6DOF, cyberspace, VRML and Second Life.
