Abstract
The presently disclosed subject matter relates to an eye tracking method and device. The method can include receiving image data indicative of at least two images of a user's eye, identifying, in each image, regions related to the eye limbus; determining geometrical representation of the limbus structure, and determining a three-dimensional position and gaze direction of the user's eye (i.e. full six degrees of freedom of the eye) by triangulation of the geometrical representation of the limbus structure of at least two images.
