{"pk":27813,"title":"A Hidden Markov Model for Analyzing Eye-Tracking of Moving Object","subtitle":null,"abstract":"Eye-tracking provides an opportunity to generate and analyzehigh-density data relevant to understanding cognition. How-ever, while objects in the real world are often dynamic, eye-tracking paradigms are typically limited to assessing gaze to-ward static objects. In this study, we propose a generativeframework, based on a hidden Markov model, for using eye-tracking data to analyze behavior in the context of multiplemoving objects of interest. We apply this framework to ana-lyze data from a recent visual object tracking task paradigm,TrackIt, for studying selective sustained attention in children.We also present a novel ‘supervised’ variant of TrackIt that weuse to tune and validate our model, while providing insightsinto the visual object tracking abilities of children and adults","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"eye-tracking"},{"word":"Visual object tracking"},{"word":"hidden Markov model"},{"word":"TrackIt"},{"word":"Selective sustained attention"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/92r3s94h","frozenauthors":[{"first_name":"Jaeah","middle_name":"","last_name":"Kim","name_suffix":"","institution":"Carnegie Mellon","department":""},{"first_name":"Shashank","middle_name":"","last_name":"Singh","name_suffix":"","institution":"Carnegie Mellon","department":""},{"first_name":"Anna","middle_name":"Vande","last_name":"Velde","name_suffix":"","institution":"Carnegie Mellon","department":""},{"first_name":"Erik","middle_name":"D","last_name":"Thiessen","name_suffix":"","institution":"Carnegie Mellon","department":""},{"first_name":"Anna","middle_name":"V","last_name":"Fisher","name_suffix":"","institution":"Carnegie Mellon","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27813/galley/17452/download/"}]}
