1. A method of tracking eye-gaze, the method comprising emitting light having a certain wavelength; transferring the light to the retina of an eye; the wavelength of the light being such as to make the fovea of the eye resolvable; detecting light that is reflected from said eye to form detection information including the resolvable fovea; mapping the detection information to a predetermined surface, said surface being located at a distance from said eye, the location of the fovea on said surface forming an eye-gaze point.
