Automatic calibration of an eye tracking system involves capturing a plurality of eye measurements, wherein each said eye measurement relates to a corresponding eye gaze position of a human eye; determining a set of statistics data from said plurality of eye gaze measurements; comparing said set of statistics of said eye gaze measurements with a set of statistics relating to a plurality of pre-measured eye gaze positions of at least one person; and as a result of said comparison, determining a calibration correction factor which, when applied to said statistics of said eye gaze measurement, give an optimum match between said statistics of eye gaze measurement and said statistics of predetermined eye gaze positions.
