In the design of spatial auditory displays, listener interactivity can promote greater immersion, better situational awareness, reduced front/back confusion, improved localization, and greater externalization. Interactivity between the listener and their environment has traditionally been achieved using a head tracker interface. However, trackers are expensive, sensitive to calibration, and may not be appropriate for use in all physical environments. Interactivity can be achieved using a number of alternative interfaces. This study compares learning rates and performance in a single-source auditory search task for a headtracker and a mouse/keyboard interface within a single source and multi-source context.
