Abstract
The authors describe the real-time acoustic display capabilities developed for the virtual environment workstation (VIEW) project. The acoustic display is capable of generating localized acoustic cues in real time over headphones. An auditor symbology, a related collection of representational auditory objects or icons, can be designed using the auditory cue editor, which links both discrete and continuously varying acoustic parameters with information or events in the display. During a given display scenario, the symbology can be dynamically coordinated in real time with three-dimensional visual objects, speech, and gestural displays. The types of displays feasible with the system range from simple warnings and alarms to the acoustic representation of multidimensional data or events.
