Abstract
Abstract
Fatigue is a complex physiological phenomenon that reflects worsening physical function and can lead to poor work performance, safety and health conditions. The research targets to obtain the degree of eye fatigue of college students in fixed sitting posture. An eye movement detection method was proposed in this paper. Using the wireless transmission eye tracker and its supporting software from the American Laboratory of Applied Sciences (ASL), three basic types of eye movements were examined, including blink, gaze, and saccade. The results show that with the increase of fatigue, participants’ blink time increased first and then decreased. During fatigue, the pupil diameter increased by about 91% and the percentage of fixation time decreased by about 31.31%. Compared with waking state, the average fixation time increased by about 9%, saccade distance decreased by about 40%. The research results can provide reference for fatigue monitoring and accident prevention.
