Abstract

A method for determining a direction of gaze of an eye for data glasses. The method includes: reading distance values and speed values, which represent a distance between laser sensors for emitting laser beams and surface intersection points of the laser beams on the eye and also surface speeds at the surface intersection points; classifying the distance values and the speed values in order to obtain classification values which indicate the parts of the eye associated with the surface intersection points; estimating position values which represent positions of the laser sensors using the distance values, the speed values, and the classification values; and ascertaining a gaze direction value which represents the gaze direction using the position values, the distance values, and the speed values.
