Abstract

A calibration method for an eye tracker provides for the defining of at least one first region of attraction of a first image to be displayed to a user; acquiring a first sequence of data relative to the eye movement of a user who is looking at the first image by means of an eye tracker; calculating at least a plurality of first calibration positions by means of respective calibration functions on the basis of a first gaze determined from the first sequence of data relative to eye movement; assigning a first score to each calibration function on the basis of the respective first calibration position and the first region of attraction; and selecting one of the calibration functions on the basis of the score.
