Abstract:
Circuitry of a gaze/eye tracking system obtains one or more images of a left eye and one or more images a right eye, determines a gaze direction of the left eye based on at least one obtained image of the left eye, determines a gaze direction of the right eye based on at least one obtained image of the right eye, determines a first confidence value based on the one or more obtained images of the left eye, determines a second confidence value based on the one or more obtained images of the right eye, and determines a final gaze direction based at least in part on the first confidence value and the second confidence value. The first and second confidence values represent indications of the reliability of the determined gaze directions of the left eye and the right eye, respectively. Corresponding methods and computer-readable media are also provided.

Claim (Index 10):
The method for determining a gaze direction of a user of  claim 8 , wherein:\n determining the first reliability parameter or the second reliability parameter, respectively, is further based on:\n a position of a glint relative to a cornea of the left eye or the right eye, respectively; \n a distance between the glint and a cornea center of the left eye or right eye, respectively; \n a position of the glint relative to a pupil of the left eye or right eye, respectively; \n a distance between the glint and a center of the pupil of the left eye or right eye, respectively; \n an intensity of the glint detected on the left eye or the right eye respectively; \n a contrast level between the pupil of the left eye or the right eye, and an iris of the left eye or right eye, respectively; \n a position of the glint relative to an edge of the pupil of the left eye or the right eye, respectively; \n a parameter indicating a number of image pixels located along an edge of the pupil of the left eye or the right eye, respectively; \n a difference between a predicted glint position and a detected glint position on the left eye or the right eye, respectively; \n a shape of the glint on the left eye or the right eye, respectively; \n a number of glints detected on the left eye or the right eye, respectively; or \n a parameter indicating a degree of spatial distribution of the image pixels located along the edge of the pupil on the left eye or the right eye, respectively.
