Abstract：It is of great significance for humans to recognize facial expression information quickly and accurately. The key to the study of facial expression recognition is whether researchers can find appropriate index to investigate the facial expression recognitionprocess.Recently, eye-tracking technique in facial expression recognition has been attracting a lot of interest because of its high sensitivity in tracking the movement of fixations and the advantage of high temporal resolution. Previous studies have shown that the eye movement pattern of facial expression recognition is affected by many factors, but to our knowledge, no systematic review of relevant studies and their influencing factors has been published. This paper summarizes the influencing factors of eye movement pattern in facial expression recognition, and suggests that the eye movement pattern is mainly influenced by facial configural information, cognition factors and emotionrecognition disorder factors. Combined with these three factors, this paper points out the problems existing in the existing research, and provides new suggestions for future research.
