Gaze analysis method and apparatus

A gaze analysis method has following steps. When detecting at least one face in an image, according to a face angle and an eye angle, a gazing angle is calculated, and whether the gazing angle falls within a first range is determined, wherein the eye angle is obtained according to information of irises and scleras of left and right eyes. A differential value between a focusing distance and a spacing distance from the face to the object falls within a second range is determined if the gazing angle falls within the first range, and a detecting result whether the differential value falls within the second range is used to determine whether the object is gazed, wherein the focusing distance is determined according to the information of the irises and scleras of the left and right eyes.
