{"pk":50213,"title":"Eye tracking in the real world: a graph-theoretical analysis and comparison to virtual realty","subtitle":null,"abstract":"Is virtual reality (VR) necessary to conduct complex immersive eye-tracking studies or can similar data be recorded and analyzed in the real world? \n\nWe adapted a spatial navigation paradigm from VR to the real city Limassol. Specifically, we combined a free exploration of 130 min with two pointing tasks while recording eye-tracking, head-tracking and GPS data. We labeled the eye-tracking data with a new classification pipeline and found a similar gaze distribution over object categories in both the real world and VR. Furthermore, we hand-labeled fixations on buildings to apply a graph-theoretical analysis. When comparing our results with VR we found some differences (e.g. graph density, diameter), but also many similarities in viewing behavior (e.g. hierarchy index, gaze-graph-defined landmarks).  \n\nOverall, our work showcases the feasibility of complex eye-tracking experiments in the real world and highlights the similarity of viewing behavior in both the real world and virtual reality.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Spatial cognition; Vision; Case studies; cognitive neuropsychology; Eye tracking"}],"section":"Member Abstracts with Poster Presentation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/7p1277tc","frozenauthors":[{"first_name":"Jasmin L.","middle_name":"","last_name":"Walter","name_suffix":"","institution":"University of OsnabrŸck","department":""},{"first_name":"Debora","middle_name":"","last_name":"Nolte","name_suffix":"","institution":"University of OsnabrŸck","department":""},{"first_name":"Paula","middle_name":"","last_name":"Vondrlik","name_suffix":"","institution":"University of OsnabrŸck","department":""},{"first_name":"Lane","middle_name":"","last_name":"von Bassewitz","name_suffix":"","institution":"University of OsnabrŸck","department":""},{"first_name":"Luna","middle_name":"","last_name":"Dšring","name_suffix":"","institution":"University of OsnabrŸck","department":""},{"first_name":"Jonas","middle_name":"","last_name":"Scherer","name_suffix":"","institution":"University Bielefeld","department":""},{"first_name":"Martin","middle_name":"M.","last_name":"MŸller","name_suffix":"","institution":"University Bielefeld","department":""},{"first_name":"Peter","middle_name":"","last_name":"Kšnig","name_suffix":"","institution":"University of OsnabrŸck","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2025-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/50213/galley/38175/download/"}]}
