Abstract: It was investigated whether the important driving information such as a pedestrian in the right and left peripheral visual fields can be recognised faster using tactile warning system as compared with auditory warning system. The participants were required to simultaneously carry out a tracking task, a switch pressing task such as selection of light-on function, and a judgement task of important information which randomly appeared to the right or left peripheral visual field. The tracking error, the percentage correct of switch pressing, and the response time to the right or left peripheral stimulus were measured. It was examined how age, the modality of alarm presentation (auditory or tactile), and the directional cue affected the performance above. The response time of the tactile warning was shorter than that of the auditory warning. The addition of directional cue of warning presentation affected the performance, and the directional cue enhanced the performance.
