optical methods of tracking human movement

Optics can also serve to track our motion. An elementary method of optical tracking involves fastening multiple lights to a glove or body suit and then tracking them in three-dimensions, but this only tracks a narrow quantity of points. Gesture interpretation by computers is already underway. This involves computer simulation of the structure and motion by hands, arms, and face -- integrating concepts across the fields of anatomy, kinesiology, and sight perception.

Interactive contact between humans and computers built on sound is another vital element of virtual reality. Conveniently, creating a realistic sound environment involves fewer technological challenges than artificially creating 3D pictures or realistic tactile and motion interface. A good surround-sound audio system can provide high quality computer-to-human sound transferral to accompany things and events in Virtual Reality. For sophisticated applications, "aural ray tracing" can function to simulate the effects of several connections between audio signals and surfaces in the virtual setting. There is additional discussion at Virtual Tours Maple Grove, Minnesota of related VR material.
