1. A method for eye gaze tracking, comprising the steps of: creating a set of reference points in a reference coordinate system; acquiring at least one image of at least one of a user's corneas, said image having image aspects in an image coordinate system and including reflections of said reference points; defining a mathematical relationship between said reference coordinate system and said image coordinate system; mapping said image aspects from said image coordinate system to said reference coordinate system using said mathematical relationship; and computing a point of regard from said mapped image aspects.
