Abstract:

The assessment of air traffic controllers' fatigue is an important research topic which needs sustainable efforts. The real-time measurement of controller's fatigue has important implications for the safe operation of air transport system. This paper proposes to use eye movements to measure air traffic controllers fatigue, in which the eye movement data in normal and fatigue states are collected using faceLAB5.0 system. The performance data, eye blink frequency, and pupil diameter of the controllers are compared and analyzed. The experiment results show that compared with normal state when controller felt fatigue (i) blink frequency is increased; (ii) the pupil diameter is reduced. With the increase of task time, the performance of the subjects deteriorate, the blink frequency increase, and the pupil diameter decrease, indicating the changing of working state from normal state to fatigue state. The study shows that blink frequency and pupil diameter can effectively indicate fatigue state of the controller and can fully depict the influence of different working periods on the working status of the controller, and thus provides a theoretical basis for developing a practical fatigue monitoring system.

Key words: air traffic control, control fatigue, eye movements, pupil diameter, blink frequency
