Abstract: Various implementations determine gaze direction based on a cornea center and (a) a pupil center or (b) an eyeball center.

The cornea center can be determined (e.g., using an average cornea radius, or a previously measured cornea radius or using information from a second glint). The cornea center and a pupil center or eyeball center may be used to determine gaze direction.
