*This abstract for appeared for patent application  number 18189520 Titled 'METHOD FOR DETERMINING A CURRENT VIEWING DIRECTION OF A USER OF DATA GLASSES WITH A VIRTUAL RETINA DISPLAY AND DATA GLASSES'

==Simplified Explanation==

The abstract describes a method for determining the current viewing direction of a user wearing data glasses with a virtual retina scan display. The method involves projecting infrared laser beams onto the user's eye and capturing images of the reflected beams. By analyzing the pupil contours in these images, the user's instantaneous viewing direction can be determined by comparing the shape of the pupil with a reference shape.


==Original Abstract Submitted==

A method for determining a current viewing direction of a user of a pair of data glasses having a virtual retina scan display. The method includes at least the method steps: projecting at least substantially parallel infrared laser beams onto an eye of a user of the data glasses, acquiring two-dimensional images from the infrared laser beams reflected back by the eye of the user, and determining pupil contours in the acquired two-dimensional images. The instantaneous viewing direction of the user of the data glasses is ascertained from a comparison of an instantaneous elliptical shape of the pupil contour with an elliptical shape of a reference pupil contour.
