1. A method of eye gaze tracking, the method comprising:
- receiving, at one or more computer systems, first tracking information obtained from one or more magnetic sensors tracking a first magnetic contact lens associated with a first eye of a wearer;
receiving, at one or more computer systems, second tracking information obtained from one or more video-based sensors tracking the first magnetic contact lens using a first set of one or more reflective patterns of the first magnetic contact lens;
generating, with one or more processors associated with the one or more computer systems, augmented tracking information based on the first tracking information obtained from the one or more magnetic sensors tracking the first magnetic contact lens and the second tracking information obtained from the one or more video-based sensors tracking the first magnetic contact lens using the first set of one or more reflective patterns of the first magnetic contact lens;
determining, with the one or more processors associated with the one or more computer systems, eye gaze information based on the augmented tracking information; and
performing, with the one or more computer system, one or more actions based on the determined eye gaze information.

Abstract
Methods of eye gaze tracking are provided using magnetized contact lenses tracked by magnetic sensors and/or reflecting contact lenses tracked by video-based sensors. Tracking information of contact lenses from magnetic sensors and video-based sensors may be used to improve eye tracking and/or combined with other sensor data to improve accuracy. Furthermore, reflective contact lenses improve blink detection while eye gaze tracking is otherwise unimpeded by magnetized contact lenses. Additionally, contact lenses may be adapted for viewing 3D information.
