Abstract: This study examined the issues related to tactile displays and the detectability of vibrotactile patterns as combat assault maneuvers were being performed. Three obstacles were used in this study: tires, windows, and high crawl. A baseline condition, in which participants received tactile patterns while standing, was also included in the analysis. In the baseline condition, participants detected and identified 100% of the tactile patterns. Analysis of the obstacle data showed that the obstacles had a significant effect on the detection and identification of the tactile signals. Participants detected 62.5% of the tactile patterns during the high crawl, which was significantly lower than for the tires and windows, with 92% and 88% of signals detected, respectively. With regard to the correct identification of tactile patterns, participants correctly identified 51% of the patterns during the high crawl, as compared to 88.5% for the tires and 77% for the windows. There were no significant differences in the response times.
