Abstract
Methods and systems for eye gaze tracking are provided, in which a plurality of images of at least one eye are received and, for each image of the eye(s), a plurality of stable vascular points associated with a vasculature of the eye(s) are identified. Based on the identified stable vascular points in the received images of the eye(s), a gaze angle of the eye(s) is determined.
