Humansystems was tasked by DRDC Toronto (formerly DCIEM) to undertake a Human Factors (HF) controlled trial to evaluate the new Visor Attachment Sub-System (VASS) design and gather additional input to support the development of the Ballistic Visor Statement of Requirement (SOR). A three-day field trial was undertaken at CFB Winnipeg over the period of October 6 - 8 1997. Thirteen regular force infantry soldiers completed a battery of human factors tests while wearing up to four different Visor Attachment Sub-System (VASS)/Visor conditions in a repeated measures design: two ½ face visors and a full face visor with the new VASS, and one half face visor with the old VASS. All tests included a helmet alone or no VASS condition as a baseline control. During each test, the order of conditions was balanced among participants. Human factors tests included assessments of attachment, usability, performance of select obstacle and battle tasks, marching, equipment, vehicle and clothing compatibility clash, and maintainability. Data collection included questionnaires, focus groups, performance measures and HF observer assessments. Weapons and equipment compatibility and durability were ranked as the most important criteria for VASS design, with weapons and equipment compatibility, and visual capability as the most important visor criteria. For compatibility, there were no significant differences between the VASS designs and considerable clash observed and reported for visor compatibility
