Using Virtual Environments to Prototype Auditory Navigation DisplaysBy Walker, Bruce N., PhD; Lindsay, Jeffrey, BS; Assistive Technology, Vol. 17, No. 1, pp. 72-81
Publication Date: Spring 2005
Article focuses on the need for orientation and navigation aids for people with visual disabilities, and discusses how the Georgia Tech System for Wearable Audio Navigation (SWAN) was developed with the help of a virtual environment (VE) in its design, evaluation, and refinement. The VE allowed the researchers to test a greater variety of sounds and configurations due to its greater flexibility, including those that could not have been evaluated without the VE system. Questions are addressed regarding sound design, system behavior, and user interface design, as the researchers believe that improved designs should result from more comprehensive and scientific methods of assistive technology development. Considerations regarding the overuse and external validity of the utilization of VE for design solutions are discussed.
