Proceedings of ECCV 2022. https://link.springer.com/chapter/10.1007/978-3-031-20071-7_40 https://lamar.ethz.ch/</ref> In this way AR glasses provide hands-free, heads-up access to information – for example showing navigation cues, text annotations, or [[3D model]]s superimposed on actual objects – without obscuring the user’s natural vision.
