Abstract
This experiment built on previous SIREQ-TD studies by quantifying the performance and utility of head-mounted, heads-up and weapon-mounted visual displays during a wayfinding and target detection task. A four-day field trial took place at Ft. Benning, Georgia with sixteen regular force infantry soldiers participating. Participant soldiers navigated 1200-metre routes through wooded terrain using an enhanced wayfinding aid in each of three display conditions. As a secondary task, participants were required to detect and engage targets on their route. Three configurations for an enhanced wayfinding aid were investigated: 1) A head-mounted occluded display featuring a wayfinding display generated by the Future Infantry Navigation Device (FIND) system. 2) A head-mounted non-occluded virtual retinal display featuring a wayfinding display generated by the FIND system. 3) A weapon mounted Garmin e-trex GPS on the “Navigate” page and showing the “Big Compass” display. While questionnaire and focus group results indicated the participants’ preference for the weapon-mounted display over the two head-mounted displays, performance results indicated no significant difference between the three displays in target engagement performance. Additionally there were only small differences in wayfinding performance between the three displays. Of the two head-mounted displays, the virtual retinal display was strongly preferred by the participants.
