Abstract:
Disclosed is a system and method for tracking a user's eye using structured light. The structured light system is calibrated by training a model of surface of the user's eye. A structured light emitter projects a structured light pattern (e.g., infrared structured light) onto a portion of the surface of the eye. From the viewpoint of a camera, the illumination pattern appears distorted. Based on the distortion of the illumination pattern in the captured image, the eye tracking system can determine the shape of the portion of the user's eye that the structured light is incident upon. By comparing the determined shape of the portion of the user's eye to the model, the orientation of the eye may be determined. The eye tracking system or elements thereof may be part of a head-mounted display, e.g., as part of a virtual reality system.

Claim (Index 12):
The eye tracking unit of  claim 10 , wherein the eye orientation estimation module is configured to:\n estimate a direction of a first pupillary axis of the first eye using the first captured image; and estimate the first foveal axis of the first eye based on the estimated direction of the first pupillary axis and based on an offset between the first pupillary axis and the first foveal axis.
