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.
