Soldiers performed a battery of indoor and field tests with each of three Night Vision Goggle (NVG) mounting systems for the AN/PVS-504A goggle: US head mount, Canadian head mount, and US helmet mount. Human factors measures included questionnaires, focus groups and Human Factors (HF) observer assessments. The US helmet mount was well liked for its NVG flip-up capability, speed and ease of mounting the NVG once the helmet strap was attached, and general comfort. While the US helmet mount was well liked for its tilt angle adjustment, soldiers were frustrated that the mechanism did not include a vertical adjustment. As well, soldiers expressed concerns with NVG stability on the helmet. The head mounts were liked for their stability but the stability tended to come at the expense of pressure point discomfort on the head, jaw and neck, and headaches; the Canadian head mount was clearly considered much worse than the US head mount. Participants preferred a combined solution that would include both the US helmet mount and the US head mount. A combined US head and helmet mount system would satisfy almost all participants (93%) in this study. Suggestions are provided for improving the helmet mounting system.
