This study examined the utility and usability of presenting directional information using a tactile modality with a view to determining the optimal site of stimulation and number of tactors for a tactile infantry wayfinding aid. The three tactile designs examined varied in the location on the body, the number of tactors, and the complexity of the information presented (direction information versus both direction and angular distance information). Eight-tactor systems on both the head and chest were investigated, as well as a four-tactor system on the head. The experiment was conducted at Fort Benning, Georgia, U.S.A. with eighteen Canadian Forces infantry soldiers. All participants were required to execute a static wayfinding task with all three tactile designs and a dynamic wayfinding task with one of the three designs. Objective performance measures for the static task included the time to identify the waypoint bearing, the accuracy of the waypoint heading, the misdirection of heading, and the number of reversals. For the dynamic task objective measures included the number of inquiries for the navigation cues, the average time for such inquiries and the difference between the actual distances traversed from the real distance to each waypoint. Subjective measurements from questionnaire data included acceptance ratings of the ease of use, acceptance for land navigation, situational awareness, and mental demand. Participants ranked all three designs upon completion of the expe
