While this is well-known, visual attention models often focus on bottom-up mechanisms. Existing works have analyzed the effect of high-level cognitive tasks like memory or visual search on visual behavior; however, they have often done so with different stimuli, methodology, metrics and participants, which makes drawing conclusions and comparisons between tasks particularly difficult. In this work we present a systematic study of how different cognitive tasks affect visual behavior in a novel within-subjects design scheme. Participants performed free exploration, memory and visual search tasks in three different scenes while their eye and head movements were being recorded. We found significant, consistent differences between tasks in the distributions of fixations, saccades and head movements. Our findings can provide insights for practitioners and content creators designing task-oriented immersive applications. info:eu-repo/grantAgreement/ES/AEI/PID2019-105004GB-I00 info:eu-repo/grantAgreement/ES/AEI/PID2022-141539NB-I00 info:eu-repo/grantAgreement/EC/H2020/682080/EU/Intuitive editing of visual appearance from real-world datasets/CHAMELEON This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 682080-CHAMELEON info:eu-repo/grantAgreement/EC/H2020/956585/EU/Predictive Rendering In Manufacture and Engineering/PRIME This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 956585-PRIME info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.7 2023 COMPUTER SCIENCE, SOFTWARE ENGINEERING 14 / 132 = 0.106 2023 Q1 T1 2.056 2023 Computer Graphics and Computer-Aided Design 2023 Q1 Software 2023 Q1 Signal Processing 2023 Q1 Computer Vision and Pattern Recognition 2023 Q1 10.4 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Martín, Daniel Universidad de Zaragoza (orcid)0000-0002-0073-6398 Serrano, Ana Universidad de Zaragoza (orcid)0000-0002-7796-3177 Gutiérrez, Diego Universidad de Zaragoza (orcid)0000-0002-7503-7022 Masia, Belén Universidad de Zaragoza (orcid)0000-0003-0060-7278 5007 570 Universidad de Zaragoza Dpto.
