Abstract
This trial investigated the effectiveness of three different visual display conditions (occluded head-mounted display, see-through prism display, and off-head tablet display), as compared to a paper map and compass control condition, for displaying digital map information in the field for navigation, mission planning and execution, platoon coordination, and battlefield awareness. This experiment was conducted at Fort Benning, Georgia with ten Canadian Forces infantry soldiers (Leaders) during daytime missions. These missions required a platoon of dismounted infantry to navigate wooded terrain to an objective rendez-vous, plan and brief an assault on an objective building in a mock village, maneuver to assault positions, and then to execute the urban assault. Human Factor (HF) measures included assessments of route navigation, and user assessments of mission performance measures, visual display effectiveness, workload and attentional demands. Data collection included participant subjective comments, questionnaires, and focus group discussions. The results of this experiment indicate that the use of digital map information is useful and desirable for infantry soldier tasks. Participants noted that the digital map display enabled all sections to obtain a comprehensive, common operating picture of the battle while maintaining stealth and unit separation. Situation awareness was also improved with the digital map conditions, specifically for knowing the location and status of the
