The research of the eye-movement components of aviation security screeners' activities by using Eye-tracking technology in order to develop intelligent fatigue control systems
In this paper, research which concerning the fatigue' effects on the aviation security screeners' oculomotor activity have been shown. The necessity of using intellectual fatigue control systems of airports' aviation security specialists has been justified. The analysis of possible aviation security screeners' functional condition diagnostic devices been carried out and the Eye-tracking technology has been chosen as having the greatest advantages. Experimental studies of the fatigue factor were conducted on the basis of two international airports in Ulyanovsk with the participation of 22 aviation security personnel. As a result, aviation security screeners' potential fatigue markers which have the most significant changes and consistent with previous studies by other authors were identified. As a result of solving the task of testing statistical hypothesis, it has been established that such oculomotor reactions like average pupil diameter, blink frequency and blink duration average can be used to diagnose the aviation security screeners' functional state, while the saccade frequency has not significantly changed during the research period and it is potentially not suitable for monitoring. The scientific originality of the results is the expansion of knowledge in the field of human factors associated with fatigue. Subject to a series of additional studies, the the oculomotor activity' identified markers can be used to develop aviation security screeners' intellectual fatigue control systems.
