Furthermore, eye-tracking sensors enables novel ways to interact with user interfaces of AR glasses, improving thus the user experience compared to other wearables. In this work, we present a novel approach to track the user's eye by scanned laser feedback interferometry sensing. The main advantages over modern video-oculography (VOG) systems are the seamless integration of the eye-tracking sensor and the excellent robustness to ambient light with significantly lower power consumption. We further present an algorithm to track the bright pupil signal captured by our sensor with a significantly lower computational effort compared to VOG systems. We evaluate a prototype to prove the high robustness against ambient light and achieve a gaze accuracy of 1.62\\,$^\\circ$, which is comparable to other state-of-the-art scanned laser eye-tracking sensors. The outstanding robustness and high integrability of the proposed sensor will pave the way for everyday eye-tracking in consumer AR glasses.<\/jats:p>","DOI":"10.1145\/3530881","type":"journal-article","created":{"date-parts":[[2022,5,13]],"date-time":"2022-05-13T22:17:43Z","timestamp":1652480263000},"page":"1-18","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["A Highly Integrated Ambient Light Robust Eye-Tracking Sensor for Retinal Projection AR Glasses Based on Laser Feedback Interferometry"],"prefix":"10.1145","volume":"6","author":[{"given":"Johannes","family":"Meyer","sequence":"first","affiliation":[{"name":"Robert Bosch GmbH, Renningen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Schlebusch","sequence":"additional","affiliation":[{"name":"Robert Bosch GmbH, Renningen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enkelejda","family":"Kasneci","sequence":"additional","affiliation":[{"name":"University of T\u00fcbingen, Tubingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2022,5,13]]},"reference":[{"key":"e_1_2_2_1_1","unstructured":"2014.
