Assessment of Pilots Mental Fatigue Status with the Eye Movement Features

Conference paper
Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 781)


With the domain of aero technics, aviation mental fatigue research has been aimed at preventing the tragedy caused by fatigue flights. There are specific effects of the mental fatigue on behavioral performance in pilots, characterized as a decrease of reaction rate and distractibility of attention. Fourteen subjects completed an experiment with visual search tasks and simulated flight task. The eye movement data were recorded by the eye tracker with 120 Hz of the sampling rate. The results of the questionnaire showed that the fatigue value in the fatigue periods was higher compared with the awake periods. Moreover, the results of eye movement features showed that the PERCLOS and blinking frequency amplitude increases monotonically with increasing fatigue value during the task. Lastly, the conclusion can be made that the measurement of eye movement pattern can be used to assess and forecast pilots mental fatigue status.
