Computer software has taken an increasingly larger role in the U.S. Navy. It is used in nearly every facet of naval operations, from administrative chores to controlling complex weapons systems. Because of the high cost of software and the potential for inadvertent misuse, it is important that software be easy to use and understand. This thesis explores the methods and techniques available for conducting software usability evaluations. Using one of the methods described in this thesis, actual software usability testing is done on a recently developed computer-based training CBT program. The CBT program evaluated in this study is designed to instruct helicopter pilots in the use of the ANAVS-7 ANVISHUD. The device is an advanced night vision goggle system that is comprised of the ANAVS-6 ANVIS night vision goggle NVG set and a Heads-Up Display HUD. This thesis describes the usability test conducted on the ANVISHUD CBT and establishes a methodology that can be used, not only on future versions of the ANVISHUD CBT, but on other PC oriented software. The result of this usability test show that improvement can be made to the navigation method used by the CBT and the presentation of instructional material.
