computer simulated environments

Virtual reality is a computer-created setting with which several people can interact with elements of three dimensions with the involvement of sight, hearing, and (in some measure) touch and locomotion. One's sense of believability in such a world increases with: (1) more range and depth of sensory data processing potential actively involved in the communication between humans and computers (e.g. amount of field of vision, resolution of visual pictures, fidelity of sound interaction, number and extent of body members actively involved in locomotor and kinesthetic interaction); and (2) more quickness and intelligence of the interaction between humans and computers, especially as the behavior of artificially-generated elements more closely conforms to the tangible and other laws that direct their real-world equivalents. Differences from the latter occur for surreal world uses. In any event, even in those applications the gap from real-world behavior should be managed to make an enough perception of reality for one to be meaningfully engaged. If the setting is too bizarre, then believable interaction fails. Technical discussion of related subjects at MediaSculp: QTVR Gallery .

A virtual reality environment must engage vital sensory mechanisms with sufficient realism to provide participating people a feeling of being in a real-world situation. Given the constraints of present day applied science, this usually entails display screens that span much of the human range of sight with satisfactory resolution, high quality surround sound, and communication between a person and computer built on hand and head location, movement, and patterning that updates more than 50 times per second. More high-performance tactile and motion interaction that involves motion by the rest of the body and engages senses other than vision, hearing, and touch are generally above present day base-line standards for Virtual Reality. These higher-order functions may, however, become what is expected for Virtual Reality (VR) in the future. Discussion of similar topics at Virtual Tours Fairview Park, Ohio .
