bidirectional interaction between humans and computers

A necessary but not sufficient characteristic of Virtual Reality is causal-chain human-computer interface. Human-to-computer communication may have computer tracking of finger, hand, head, eye and/or body movement and/or speech interpretation. Information transfer from a computer to a person may have multi-dimensional image projections, sound generation, and haptic (touch and motion) simulation. Linked page Mellott's VR Page also has different useful information on VR.

In the event that the core criteria for Virtual Reality (VR) are an engaging and immersive computer-generated environment, then the next challenge for simulating reality is the speed of the communication between human and computer. Latency is the duration of the lag in the communication between human and computer caused by technical constraints in data processing and transmission. In the physical world, many forms of communication between people and their setting happen immediately. A vital challenge for artificially creating the physical world is decreasing response lag to the point at which humans do not frequently notice it. With significant developments in computer operating capacity, response lag is now being reduced and the immediacy of virtual constructs improved. Also visit Virtual Tours Wyoming .
