FIELD: medicine.
SUBSTANCE: group of inventions relates to field of medicine. System for tracing point of look of observer, observing object, contains device for registration of observer's eye image, means for presentation of luminescent marker on observed object or connected with it and means for determination of position of reflection of marker by cornea on eye and the centre of pupil. Device for determining difference in position between reflection of marker by cornea and pupil centre to provide difference signal, and means for changing position of marker on observed object or connected with it depending on difference signal in order to have reflection of marker by cornea and pupil centre coinciding, for renewing marker position until coincidence with look point.
EFFECT: application of said group of inventions will make it possible to increase rate and accuracy of look tracing.
