METHOD FOR DETERMINING A CURRENT VIEWING DIRECTION OF A USER OF DATA GLASSES WITH A VIRTUAL RETINA DISPLAY AND DATA GLASSES - A simplified explanation of the abstract

  • This abstract for appeared for US 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

This 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 parallel infrared laser beams onto the user's eye and capturing two-dimensional images of the reflected beams. The pupil contours in these images are then determined. By comparing the shape of the pupil contour with a reference shape, the method can ascertain the user's instantaneous viewing direction.


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.
