In some embodiments, the boundaries of a gaze detection coordinate system can be determined from a spatial relationship between a user eye and gaze detection elements such as illuminators and at least one light sensor positioned on a support structure such as an eyeglasses frame. The gaze detection coordinate system allows for determination of a gaze vector from each eye based on data representing glints on the user eye, or a combination of image and glint data. A point of gaze may be determined in a three-dimensional user field of view including real and virtual objects. The spatial relationship between the gaze detection elements and the eye may be checked and may trigger a re-calibration of training data sets if the boundaries of the gaze detection coordinate system have changed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gaze detection in a see-through, near-eye, mixed reality display","description":"The technology provides various embodiments for gaze determination within a see-through, near-eye, mixed reality display device.
