Abstract
Provided is a method for identifying a gaze behavior in a three-dimensional space, comprising: acquiring eye movement data of the two eyes of a user; selecting, from the collected eye movement data, eye movement data for gaze behavior identification; calculating eye movement angular velocities, determining gaze point data corresponding to the gaze behavior; combining pieces of gaze point data, which satisfy a time proximity condition and a space proximity condition at the same time, in the gaze point data so as to obtain a gaze duration and the 3D coordinates of gaze points; and based on the combined pieces of gaze point data, determining a gaze point at which the gaze duration is longer than a second set duration, thereby identifying the gaze behavior.
