Abstract
Methods and apparatus for generating user-aware eye models. During an enrollment process, images of a user's eye are captured by one or more cameras when the eye is in two or more different orientations and at two or more different levels of display brightness. The captured images are processed to generate a 3-dimensional, user-aware eye model, for example a model of at least the eye's cornea and pupil features. The generated user-aware eye model may be used in other processes, for example in a gaze tracking process. The enrollment process may be an iterative process to optimize the eye model, or a continuous process performed while the user is using the system.
