Abstract: Methods and apparatus for glint-assisted gaze tracking in a VR/AR head-mounted display (HMD). Images of a user's eyes captured by gaze tracking cameras may be analyzed to detect glints (reflections on the cornea of light sources that illuminate the user's eyes) and the pupil. The glints are matched to particular ones of the light sources. The glint-light source matches are used to determine the cornea center of the eye, and the pupil center is determined. The optical axis of the eye is reconstructed from the cornea center and the pupil center, and the visual axis is then reconstructed from the optical axis and a 3D model of the user's eye. The point of gaze on the display is then determined based on the visual axis and a 3D model of the HMD.
