The eye gaze tracking method includes: capturing, by at least two cameras, frames of facial images when a viewer views display screen; segmenting a current frame of facial image with pre-trained eye detection model to obtain an image for left and right eyes; calculating a similarity between the current frame of facial image and each of previous N frames of facial images; if the similarity between the current frame of facial image and each of previous N frames of facial images is less than the preset threshold, detecting a position on display screen at which the eyes of the viewer gaze with pre-trained eye detection model. Embodiments of the present disclosure can improve accuracy and efficiency of eye gaze tracking.
