Abstract
The purpose of this study was to investigate the utility of alternative terrain visualization capabilities for open country terrain navigation (e.g. two-dimensional versus three-dimensional maps). Twelve regular force infantry soldiers, ranging in age from 24 to 41 years (mean = 28.6, sd = 5.6), participated in the study. Soldiers were required to navigate 2km routes at Ft. Benning, Georgia using digital maps in three different display modalities: 2D Tablet, 3D Tablet, and 3D Head Mounted Display (HMD). Three different route plans were used (i.e. a different route for each modality) to minimize the learning effects of previous missions. Wayfinding performance was recorded using a computerized Global Positioning System (GPS) tracking system. Performance measures included track deviation, obstacle avoidance, time to traverse ground, total distance travelled, distance to endpoint, and accuracy of estimating bearing and distance to an objective. Soldiers also completed a NASA TLX scale to assess how much workload they experienced. Pre Mission, Post Mission, and Exit Questionnaires, consisting of 7-point scales for acceptability, were used to collect subjective information. A repeated-measures analysis of variance was conducted for all measures (n = 12). Overall results indicated the 2D Tablet received the highest acceptability ratings of all the map modalities, with the exception of the 3D Tablet for route planning. Exit Questionnaire ratings for "overall acceptability" indicated
