    This paper describes a workload model as a function of the system complexity and task difficulty. The workload index derived is general to the various dimensions of workload measures, task dynamicity, and instabilities associated with the system of interest. We show that the variations in workload changes as the system and task parameter change View full abstract»

    The tau hypothesis predicts that observers initiate collision avoidance actions based on an integration of speed and distance. We constructed an experiment to test whether human subjects are sensitive to the critical boundary of imminent collision, even when this boundary is not defined by an integration of speed and distance. Subjects were asked to perform a simulated flight towards a barrier sur... View full abstract»

    Historically, a significant number of accidents in complex systems have been attributed to a lack of situation awareness (SA). Despite increased use of automation and improvements in display design to improve SA, re-design is unable to completely eliminate accidents of these types. One viable option is to train operators to acquire and to maintain situation awareness. We propose employing expert k... View full abstract»
