technical definitions of virtual reality

Virtual Reality can be defined by: (1) technical characteristics of the hardware used; or (2) attainment of certain perceptual effects. As an example of technical features, one can identify the minimum equipment for VR as: a three-dimensional image projection system that reacts to the location and movement of human head and eyes, spanning X% of the human scope of sight, and processing Y changes in motion each second; a 3D sound system; and a responsive glove that senses and processes hand motions for someone's commands to the virtual setting. In any event, technical definitions such as this one are replaced as applied science evolves and anticipated results for believability grow. In a similar fashion, early gramophone recordings in the early 20th century were at one time seen as "high-end audio" sound reproduction, but would not meet such a designation by comparison to present day digital technology.

To qualify as being called Virtual Reality, components within the computer-created setting also must allign with reasonable precision to the physical and biological laws relevant to their genuine equivalents. This is demanded for the computer-created objects to appear real to the higher-order functions of one's brain, not just lower-level perception. It is not enough for a geometric object to just look like a cube, it must also interact like a geometric object with respect to the quantity of matter, gravity, momentum, and other tangible laws. This is more challenging with more complex physical or even living components within an artificially-generated setting. Simulating a living entity is harder than simulating a cube.
