Abstract:
In closed-loop control tasks (e.g., flying), the human operator is required to continuously monitor visual feedback, so as to evaluate the consequence of his actions and to correct them according to his goal. A flight simulator environment allows us to evaluate the influence of control challenges such as visual feedback delays and control disturbances without endangering the human operator.
In addition, a stable simulator environment allows for more robust eye-movement and physiological recordings, which would be difficult to obtain in an actual test-flight. Eye-movement recordings can reveal the aspects of visual information that is relied on for the execution of
certain maneuvers. Meanwhile, electrophysiological recordings for heart-based and skin conductance activity as well as EEG can reflect aspects of operator workload. My talk will present work on how visual feedback visualization and latency influences both control performance and
workload. This will exemplify how control behavior in a flight simulator differs from that of a comparable compensatory tracking task. In doing so, I will convey the benefits and technical challenges involved in performing behavioral studies in a fixed-base flight simulator that is suitable for evaluating closed-loop control performance, eye- movement behavior and physiological recordings.
