Human Factors Engineering


TRAX recognizes the uncertainties associated with testing, and conducts Human Factors evaluations to analyze these factors. We are equipped to perform testing from the arid desert, to the humid tropics, to the frigid arctic.

The TRAX Human Factors (HF) team is one of the foremost and most well-trained units in service. The current HF group has accumulated an exceptional amount of experience in designing, conducting, and evaluating material and systems tests. Our experience spans from the mid-1960s through the present, and is garnered from formal training and extensive experience. The TRAX team prepares the complete package; plan, conduct, analyze, and report diverse aspects of materiel developmental tests.

Our HF team is trained in arctic, desert, and tropic regions environments, and frequently conducts extended assignments in remote locations with required HF metric equipment. We perform Human Factors Evaluations in conjunction with materials or equipment tests to analyze effects of the human/material
interface. We apply the science of anthropometrics, measurements of visual and hearing acuity, sound intensity, and vibration analysis.

We are responsible for conducting exposure testing of materials under short and long term natural environmental conditions. The TRAX HF group collects data for durability, wear, and test performance for a variety of equipment, such as chemical protective suits, man portable and mobile chemical detectors, and visual-infrared obscurant generator systems. Our HF team also assists in a variety of associated activities, including the selection and layout of test sites to determine radio frequency propagation loss and acoustic transmission phenomena, the development of human factors tests for soldier systems, and the design and construction of man pack portability courses to test human interaction and load carrying efforts.

As each project nears its end, we conduct further testing to ensure customers receive the best input. We conduct laboratory analysis and non-destructive testing (NDT) on test item failures. We structure survey questionnaires and apply debriefing and interviewing techniques to elicit responses from materiel users. Finally, all the information is compiled to determine human-item activity, proficiency, and equipment acceptance, and a report is issued to the client.
