Abstract:

This technical report describes the concept, design, development, and on-site evaluation of a 3-dimensional 3-D audio interface system for potential operational use by North American Aerospace Defense NORAD. An initial prototype phase was used to evaluate the 3-D audio interface system in an operational exercise setting giving NORAD operators the capability to conduct hands-free communication over multiple communication lines. This 3-D audio interface system enabled hands-free communications by providing a headset with 3-D audio capabilities, a boom microphone, and a push-to-talk foot-switch pedal. The 3-D audio interface system provided the sound from the three communication lines to be perceived as coming from three different spatial locations around the operator. The formal evaluation of the 3-D audio systems was accomplished during a Ballistic Missile Defense Organization BMDO exercise in late April 1997.
