sound environments

Interaction between humans and computers built on sound is another key element of virtual reality. Conveniently, creating a realistic sound world involves fewer scientific challenges than artificially creating 3D pictures or realistic haptic interface. A good surround-sound audio system can provide high performance computer-to-human sound transferral to match things and events in virtual reality. For high-performance uses, "aural ray tracing" can function to simulate the effects of multiple interactions between audio signals and surfaces in the virtual construct. Sub-page Digital Humans covers more information on this topic.

The most popular type of sound-based interaction from human beings to computers is speech interpretation. Speech recognition technology has improved considerably independently of Virtual Reality. Application of advance speech recognition systems to Virtual Reality significantly improves the scope and believability of the human to computer interface. See Virtual Tours Wyoming for more about virtual reality.

Linked page Virtual Reality also deals with such virtual reality technologies.
