Fig. 4 — (a) Visual search time of the three subjects in the larger area search. Auditory cues and contour (edge-image) cues from the HMD field expander significantly reduced search time for all subjects. (b) Mean directness of the 9 subjects in the smaller area search. In both studies, directness with either auditory or contour cues was better than without cues.
