(plural virtual realities)
- A reality that is only based in the computer.
virtual reality - Computer Definition
A computer-generated reality that projects the user into a 3D space. Using stereoscopic goggles that provide a completely immersive experience, the virtual reality (VR) system is operated by the user's head and hand movements or a physical control unit. In the past, 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 (VR), which provided a very realistic and extremely expensive simulation of the cockpit. Widely used for amusement are goggles-based VR games, which provide a more immersive effect than a PC and desktop monitor. Virtual Reality vs. Augmented Reality "Virtual" reality is entirely immersive, whereas "augmented" reality superimposes digital images or video onto the real world (see augmented reality).
