Abstract:
An eye tracking method includes: capturing, by a camera, an image of an eye; detecting, by a processing circuit, a pupil region of interest in the image of the eye; analyzing, by the processing circuit, the pupil region of interest to obtain a gaze vector of the pupil region of interest; calculating, by the processing circuit, a viewpoint of the eye according to the gaze vector based on an eye model, in which the eye model includes a matrix indicating relationship between the viewpoint of the eye and the gaze vector of the pupil region of interest; and tracking, by the processing circuit, a motion of the eye based on the viewpoint calculated using the eye model.

Claim (Index 14):
The electronic device as claimed in  claim 8 , further comprising one or more IR LED units electrically connected to the processing circuit, wherein the one or more programs further comprise instructions for:\n controlling the one or more IR LED units to provide one or more infrared rays, wherein the image of the eye are captured using the one or more infrared rays.
