Abstract
This study compares two mounting systems for the AN/PVS 504A night vision goggle, the in-service head harness and the prototype helmet-mounted system developed by Defence Research Establishment Valcartier (DREV). An experiment was conducted over the period of December 16 to 18, 2001 at Fort Benning, Georgia. The aims of this experiment were: to compare the prototype helmet-mounted NVG attachment system for the AN/PVS 504A with the in-service head-mounted attachment system for infantry soldiering tasks in wooded, open and urban environments; to evaluate the effectiveness and usability of the head-mounted and helmet-mounted NVG systems and; to identify design aspects critical to optimizing the helmet-mounted prototype for infantry soldier use. Over a period of two nights, fourteen soldiers completed a series of tasks in wooded, open and urban terrain while wearing the AN/PVS 504A NVGs. A within-subjects experimental design was used with each participant completing each task twice--once while using the in-service head mount and once while using the helmet-mounted system. Data was collected in the form of questionnaires regarding the overall acceptability of the mounts and the functionality and durability of individual mount features. Based on the results of this study, several recommendations to improve the helmet-mount are made including: preventing side to side twisting by adding a locking mechanism to eliminate play on the hinge; using a sliding rail instead of a flip-back to
