optical methods of tracking human movement

Optics can also serve to track our movement. An elementary method of optical tracking entails fastening several light sources to a glove or body suit and then monitoring their movements three dimensionally, but this only tracks a limited number of points. Gesture interpretation by computers is, even now, underway. It involves computer simulation of the structure and motion by human hands and face -- drawing from the fields of anatomy, kinesiology, and sight perception.

Interactive contact between people and computing systems based on sound is another vital part of virtual reality. Conveniently, creating a realistic sound setting involves fewer technological challenges than artificially creating 3D images or realistic tactile and motion interaction. A good surround-sound sound system can provide high quality computer-to-human sound transferral to match objects and events in Virtual Reality (VR). For high-performance applications, "aural ray tracing" can be used to recreate the effects of multiple connections between sounds and surfaces in the virtual setting.
