Through a sequence of research studies the User-Centered Design work group at the Space Naval Warfare Systems Center San Diego SSC-SD has identified a set of design principles captured in a Mission-Centered Design MCD approach to developing Human Computer Interfaces HCIs. This approach has been applied to emerging designs for the next generation land-attack Tactical Tomahawk Weapon Control System TTWCS. A Task Manager display was implemented as a key HCI design feature to address cognitive requirements for supervisory control by providing an explicit mission process representation. The representation is used to convey mission process, status, and guide attention across simultaneous tasks. The interface supports the cognitive function of mission process situation awareness as well as providing an efficient mechanism to navigate to existing TTWCS interfaces. A recent study indicates a potential reduction in both cognitive and motor workload with Task Management assistance. An operational scenario-based laboratory evaluation of a future TTWCS HCI design with Task Management and decision support aids required a single operator vice the traditional four operators to perform simultaneous planning, execution, and missile control tasks. The improved HCI design produced high performance levels with minimal workload even with only 6 hours of difference training.
