1. A gaze analysis method, executed by a gaze analysis apparatus, the gaze analysis apparatus comprising an image capturing device, a face detecting device, a face angle calculating device, an eye angle calculating device, a gazing angle determining device, an object-being-gazed determination device, and a time counting device, the method comprising:

  • detecting at least one face in an image captured by the image capturing device through the face detecting device;

    calculating a gazing angle of the face in the image according to a face angle and an eye angle of the face in the image through the eye angle calculating device, and determining whether the gazing angle falls within a first range through the gazing angle determining device, wherein the eye angle is obtained according to information of an iris and a sclera of a left eye and information of an iris and a sclera of a right eye through the eye angle calculating device;

    determining a differential value between a focusing distance and a spacing distance falls within a second range if the gazing angle falls within the first range, and determining whether the object is gazed according to a detecting result whether the differential value falls within the second range through the object-being-gazed determination device, wherein the focusing distance is determined according to the information of the iris and the sclera of the left eye and the information of the iris and the sclera of the right eye through the object-being-gazed determination device;

    calculating a continuous or accumulation time which the differential value falls within the second range, so as to obtain a gazing time through the time counting device; and

    determining whether the gazing time is larger than a specific value through the time counting device;

    wherein when the gazing time is larger than the specific value, the indication device is used for executing a corresponding command.
