Abstract
A pose of an eye of a user is determined by providing a parameterized 3D model of the eye, said model including a set of parameters which have been calibrated, acquiring (step S) at least one tracking image of the eye, identifying (step S) a plurality of characteristic features in the acquired tracking image, fitting (step S) said characteristic features with corresponding features of an optical projection of the calibrated 3D model, thereby forming a set of equations, and numerically solving (step S) the set of equations to determine the pose of the eye.
