Abstract
A gaze tracking method, system, and non-transitory computer readable medium for tracking an eye gaze on a screen of a device including a fixed camera, include calculating a parametric equation of an eye gaze vector passing through a pupil of a user and an eye ball center of the user, computing a first angle of the screen with respect to a fixed plane relative to the screen based on a preset angle of the screen and an object, calculating a current plane of the screen based on the first angle and a position of the fixed camera with respect to the screen, and calculating an intersection of the eye gaze vector calculated by the calculating the parametric equation with the current plane equation calculated by the calculating the current plane.
