Comparative Evaluation of a Monocular Head Mounted Display Device Versus a FlatScreen Display Device in Presenting Aircraft Maintenance Technical Data

摘要

As military developers provide increasingly complex weapon system, it becomesmore difficult for maintenance technicians to perform their jobs. One aspect of the technicians' world is the need to access technical information in the performance of their duties. This study investigated two electronic display systems to evaluate which enhanced technician performance more. A Head Mounted Display (HMD) device and a portable hand-held flat-screen computer were evaluated in the performance of two flightline maintenance activities. Although both display systems were fully portable and self contained, only the HMD system allowed continuous access to technical information during task performance. In most cases, technicians using the IBM system outperformed those equipped with the flat-screen computer system in terms of effectiveness and efficiency.
