Human operator performance is a key factor for proper operation of safety critical industries like process control, nuclear power plant and aviation. Several incident reports identify human error as one of the causes responsible for accidents. One way to reduce human error is to impart proper operator training which requires understanding how operators learn during training. Traditionally, learning is evaluated on the basis of subjective assessments and outcomes of the task execution. It obscures the cognitive aspect of the learning process like understanding how operator gives attention to various information sources and develops the process of decision making during the training program. In this study, we use pupil size measurement from eye tracking system to study and understand learning as participants undergo repetitive trials of simulated flight operations tasks. A derived measure based on time-frequency analysis of pupil size variation is observed to be sensitive to the process of learning during task repetition. We observe improvement in the task performance accompanied by the decrease in the proposed measure. © 2018 Elsevier B.V.
