The invited symposium session consists of four papers describing the S-PRINT project, sponsored by NASA’sHuman Research Program (HRP). The efforts undertaken as part of this project were to develop tools andempirically-based guidelines that support human performance researchers, mission planners, automationdesigners, and astronauts in long-duration missions. The Space Performance Research Integration Tool (SPRINT)project addresses aspects of the work environment that are characterized by workload transitions thatmight occur during long-duration missions. Workload transitions are a potential worst-case scenario, in whichunder-loaded astronauts experience automation failures that require immediate diagnosis and intervention. Theresearch has focused on the underload situation and on the effects that fatigue has on performance, humanperformance during overload / multitasking situations, and on automation design factors that affect operatorperformance. In this symposium, the investigators will present four papers (identified below) that describedifferent aspects of the research completed to develop the S-PRINT model. The session will show an integratedapproach of using empirical research and human performance modeling to predict operator performance inoperations that are in the design phase. In part, this symposium will highlight the way that the products fromthis research can be used to help the above-listed users (a) anticipate and avoid potential problems related tounexpected workload transitions by identifying the expected effects of operator fatigue, automation systemdesign, and task factors on overload performance, and to (b) assure systems can be designed in such a way as tooptimize performance in space exploration missions, particularly those that are experienced during longer termmissions (6+ months).
