virtual reality and computer vision

One way of human-to-computer communication is "motion capture" wherein high-order analysis of camera pictures of human movement by a computer enables the computer system to recognize key configurations and patterns of human movement. However, this method has constraints. The parts of interest of one's body must all be in view of the camera. They should not be obscured by elements of the environment or by rest of the human body. Some gestures are self-occluding in themselves. This method is also limited by lighting conditions. There is additional discussion at Glasson Murray Group Pty Ltd of similar VR topics.

The applied science of Virtual Reality remains in early formation, but is evolving rapidly. At this time, the base-line criteria for Virtual Reality have simulation of three-dimensional vision -- for example, by a head-mounted VR display, monitoring of hand location and patterning to handle artificially constructed things -- for example, by a motion-recording glove, and sound that reasonably corbehaves to objects in the simulated world. Basic artificially constructed touch through a configuration-monitoring glove is more and more common. In any event, this is still not required to meet the minimum definition of virtual reality. Linked page Virtual Tours Bakersfield, California also provides useful developments on this topic.
