proprioceptors and mechanoreceptors

Motion and touch as a method of communication from computing systems to people is not well developed. In any event, this is still important. One's brain receives macro-scale information about the locations of parts of the body from proprioceptors that monitor muscle motions. The brain also gets tiny-scale information concerning touch and texture from mechanoreceptors in the skin. Combined information from proprioceptors and mechanoreceptors tells the human about tangible attributes of things in the world. Information on ISPOT Virtual Tours may also be of interest.

Interaction between people and computing systems built on sound is another key part of virtual reality. Fortunately, creating a realistic sound setting involves fewer technological challenges than artificially creating 3D images or realistic haptic interface. A good surround-sound sound system can give high quality computer-to-human sound transmission to accompany objects and events in virtual reality. For sophisticated applications, "aural ray tracing" can function to recreate the effects of several interactions between audio signals and surfaces in the virtual environment. The site Virtual Tours Milwaukee, Wisconsin can also be useful.
