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 20):
The non-transitory computer readable storage medium as claimed in  claim 15 , further comprising instructions, which when executed, causes the processing circuit to further perform operations comprising:\n determining a center of the pupil in the image of the eye; determining a contour of the pupil in the image of the eye; and fitting an ellipse to the pupil according to the center and the contour of the pupil to obtain the pupil region of interest.
