One embodiment of the present invention is a method for computing a first gaze axis of an eye in a first coordinate system. A camera is focused on the eye and moved to maintain the focus on the eye as the eye moves in the first coordinate system. A first location of the camera in the first coordinate system is measured. A second location of the eye and a gaze direction of the eye within a second coordinate system are measured. A second gaze axis within the second coordinate system is computed from the second location and the gaze direction. The first gaze axis is computed from the second gaze axis and the first location using a first coordinate transformation.
