1. A gaze tracking system comprising:
a pupil detector operable to produce a detected pupil location of a pupil of a user by analyzing an actual pupil location of the user in one or more images captured of one or both of the user's eyes;
a confidence value determinator operable to determine a confidence value indicative of an accuracy and precision of the detected pupil location with respect to the actual pupil location and therefore an expected reliability of the detected pupil location; and
a processor operable to generate, in dependence upon the determined confidence value, one or more outputs to cause the user to modify the actual pupil location to a new actual pupil location that results in a higher determined confidence value.
