Spatialised auditory and visual cues were delivered via a wearable interface – Google Glass – and a Bone Conduction Headset to aid a search task. The aim of the study was determine which of the cues – auditory, visual or a combination of the two – would lead a user to a target in the shortest time with a minimal demand on the user’s attention. The results demonstrate that the static visual cue performed the best. The static auditory cue displayed a good level of usability and intuitiveness, especially when no visual cue was provided alongside. Our findings demonstrate that there is significant value in providing auditory or visual cues to aid a search task without inhibiting environmental awareness.
