Firstly, a to-be-analyzed facial image is captured. Then, whether the to-be-analyzed facial image conforms to a customized 3D face model is determined If not, a customized 3D face model of the to-be-analyzed facial image is created. If yes, an eye area image of the to-be-analyzed facial image is obtained. Then, according to the customized 3D face model and the to-be-analyzed facial image, head posture information is obtained. Then, an eye camera coordinate value referenced to a camera coordinate system is obtained. Then, the eye camera coordinate value is converted into an eye frame coordinate value referenced to a display frame coordinate system. Then, according to the eye frame coordinate value, the head posture information and an eyeball radius, an eyeball center point coordinate value is obtained, and accordingly a gaze coordinate value is obtained."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gaze tracking method and gaze tracking device using ihe same","description":"A gaze tracking method includes the following steps.
