Abstract:

Eye movement is related to psychology. This movement includes fixation, saccade, and pursuit movement, which serve as stimuli in the foveal area of the eyes. Eye trackers precisely record eye movement to analyze the cognitive and psychological activities of subjects. People viewing faces undergo aesthetic judgment subconsciously, and the conscious can influence the attention allocation of subjects. Faces, subjects, and task factors can change the basic eye movement pattern. The visual attention allocation of faces changes on the basis of the triangular eye movement pattern. Malocclusion, cleft lip and palate, and facial deformity can change the eye movement pattern. Eye trackers can quantify the attention deviation in abnormal faces and provide a new evaluation method to determine the effect of correcting the abnormality. Such devices objectively record the physiological changes in people during the aesthetic processing of faces, thereby facilitating the identification of the facial aesthetic pattern. In the future, eye trackers can be used to assess treatment needs, level diseases, and evaluate the curative effect of deformed faces on the basis of eye tracking data and computer science.
