METHOD AND APPARATUS FOR IDENTIFYING GAZE BEHAVIOR IN THREE-DIMENSIONAL SPACE, AND STORAGE MEDIUM

摘要

Provided are a method and apparatus for identifying a gaze behavior in a three-dimensional space, and a storage medium. The method comprises: collecting 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 at multiple sampling time points in the selected eye movement data, and on the basis of the calculated eye movement angular velocities and an eye movement angular velocity threshold value corresponding to a gaze behavior, 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 on the basis of 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. In the present invention, coordinate information of a gaze point in a three-dimensional space is acquired, and standards for time proximity and space proximity are set, such that a gaze behavior can be effectively determined in combination with a visual depth difference, and the gaze behavior in the three-dimensional space can be accurately identified.
