{"pk":29706,"title":"Modeling the Effect of Driver’s Eye Gaze Pattern Under Workload: GaussianMixture Approach","subtitle":null,"abstract":"This paper puts forward a Gaussian Mixture Model (GMM) foreye gaze behavior under workload and applies it to the analy-sis of gaze distributions in an automotive context. Specifically,it extends earlier work on Information Constrained Control(ICC) (Hecht, Bar-Hillel, Telpaz, Tsimhoni, & Tishby, 2019)(Hecht, Telpaz, Kamhi, Bar-Hillel, & Tisbhy, 2019) (Hecht etal., 2015) (Hecht, Telpaz, Kamhi, Bar-Hillel, & Tishby, 2018)by generating an ICC GMM derivative. We suggest a mea-sure for workload estimation based on the Kullback Leiblerdivergence (Dkl ) between tested eye gaze distributions and areference workload-free distribution. This derivative assumesdiagonal Gaussians that are distant from each other. Underthese assumptions, we achieve an analytical measure that hassignificantly fewer parameters than discrete grid-like distribu-tions (Hecht, Bar-Hillel, et al., 2019). Testing our measureon eye gazing data collected during real world driving experi-ments in a highway environment confirms the effectiveness ofthis approach.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Information Constrained Control; Gaussian Mix-ture Model; Eye gaze distribution"}],"section":"Poster Session 1","is_remote":true,"remote_url":"https://escholarship.org/uc/item/77n124rr","frozenauthors":[{"first_name":"Ron","middle_name":"M.","last_name":"Hecht","name_suffix":"","institution":"Advanced Technical Center Israel","department":""},{"first_name":"Ariel","middle_name":"","last_name":"Telpaz","name_suffix":"","institution":"Advanced Technical Center Israel","department":""},{"first_name":"Gila","middle_name":"","last_name":"Kamhi","name_suffix":"","institution":"Advanced Technical Center Israel","department":""},{"first_name":"Omer","middle_name":"","last_name":"Tsimhoni","name_suffix":"","institution":"Warren Technical Center","department":""},{"first_name":"Aharon","middle_name":"Bar","last_name":"Hillel","name_suffix":"","institution":"Ben-Gurion University of the Negev","department":""},{"first_name":"Naftali","middle_name":"","last_name":"Tishby","name_suffix":"","institution":"The Hebrew University of Jerusalem","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2020-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/29706/galley/19563/download/"}]}
