defining virtual reality using psychological concepts

Virtual reality is an artificially-generated object, objects, or complete setting through which one or more humans come in contact as if it were real. It is possible to make this definition more specific by specifying the base-line technical specifications needed for the communication between human and computer to be Virtual Reality. One can outline scope of sight, extent of precision of the visual display, and the range of one's hand, head, and body motion to which the computer reacts, but these technical parameters will shift with further improvements in computer power and new equipment for interaction between human and computer. For these reasons, a perception-based definition based on sufficient engagement of human cognition yields a more stable definition of virtual reality. SWFL360 covers further information on this topic.

To be responsive, a setting must respond to one's action with a high enough amount of correctness and speed to provide a person engaged a sense similar to interaction with real world elements. With present day technologies, this usually involves achieving a certain amount of computer reaction to the position, movement, and angle of the participating human's eyes or head and that of at least one hand. Computer reaction to the location, orientation, and direction of the rest of the participating person's body is important, but is not currently included in the minimal specification for Virtual Reality (VR). This also will change as technology advances. Virtual Tours Irvine, California also has information about this topic.
