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.
