Integrating Usability Engineering in the Iterative Design Process of the Land Attack Combat System (LACS) Human Computer Interface (HCI)

摘要

Usability engineering are the set of design and development practices the Space & Naval Warfare Systems Center (SSC San Diego) followed in order to ensure that the Tomahawk Operators can succeed in using the Land Attack Combat Systems (LACS) for its intended purposes. This paper presents our approach of the usability engineering activities and the results from a 1-year Fiscal Year 2003 effort for the development of the LACS Human Computer Interface (HCI). Iterative usability evaluations and design processes were conducted quarterly on the LACS HCI in order to develop the HCI that best supported the tasks of the Tomahawk Operators. Usability evaluations consisted both of Heuristic Reviews and Usability Testing. Results from these iterative evaluations were integrated into successive design builds for further evaluations.
