Abstract
Provided are methods, apparatuses, and systems for tracking a pupil of an eye of a user with degraded iris authentication accuracy. In certain examples, an eye tracking device includes a camera adapted to capture an eye image of at least one eye of a user. The eye tracking device further includes an image processor adapted to defocus the eye image in order to generate a defocused eye image. The defocused eye image comprises reduced iris authentication accuracy. The eye tracking device further includes a tracking processor configured to detect a pupil in the defocused eye image and determine a gaze direction of the user based at least in part on one or more of the defocused eye image and the pupil.
