Abstract: Various implementations disclosed herein include an inconspicuous eye enrollment for user devices through the simultaneous or near-simultaneous eye characteristic tracking and eye model updating. The implementations disclosed herein direct light towards an eye of a user to produce glint reflections and obtain, via one or more sensors, image frames comprising depictions of the glint reflections. Based on those image frames, the implementations disclosed herein track eye characteristics and update an eye model of the eye during a period of time between obtaining a first image frame of the image frames and obtaining a second image frame of the image frames.

Abstract: Methods and apparatus for providing eye model matching in a device are disclosed. When a user activates a device and the presence of the user's eye is detected, an image of the user's eye is captured. An eye model matching process is then implemented to determine a stored eye model (e.g., an eye model stored after enrollment of the eye on the device) that best matches the eye in the captured image. Determination of the best matching eye model may be based on matching between properties of the user's eye in the captured image (such as cornea and pupil features) and properties of the user's eye determined by the eye model. The best matching eye model may then be implemented in, for example, an eye gaze tracking process. In certain instances, the best matching eye model satisfies a threshold for matching before being implemented in the downstream process.
