This study aims to present sophisticated, multi-modal<br \/>data collection, which can enable accurate estimation of cognitive<br \/>load using wearable and contact-free devices. A total of 25<br \/>participants participated in six cognitive load-inducing tasks, each<br \/>presented at two levels of difficulty. Simultaneously, physiological<br \/>and behavioral data were collected from a multi-modal sensory<br \/>setup, including: Empatica E4 wristband, Emteq OCOsense<br \/>glasses, an eye tracker, a thermal camera, a depth camera and an<br \/>RGB video camera. Additionally, participants provided subjective<br \/>measures of cognitive load by completing standardized NASA<br \/>Task Load Index (NASA TLX) and Instantaneous Self-Assessment<br \/>(ISA) questionnaires following each cognitive task. Preliminary<br \/>statistical analyses were conducted on participant demographics,<br \/>performance metrics, and the perceived difficulty of tasks, as<br \/>reported in the completed questionnaires.<\/p>\n<p>\u00a0<\/p>\n\n\n\n<div data-wp-interactive=\"core\/file\" class=\"wp-block-file\"><object data-wp-bind--hidden=\"!state.hasPdfPreview\" hidden class=\"wp-block-file__embed\" data=\"https:\/\/is.ijs.si\/wp-content\/uploads\/2024\/10\/SCAI_2024_paper_6961-1.pdf\" type=\"application\/pdf\" style=\"width:100%;height:600px\" aria-label=\"Embed of SCAI_2024_paper_6961-1.\"><\/object><a id=\"wp-block-file--media-8884f314-e899-44fe-9ccd-6e10f3dea0cf\" href=\"https:\/\/is.ijs.si\/wp-content\/uploads\/2024\/10\/SCAI_2024_paper_6961-1.pdf\">SCAI_2024_paper_6961-1<\/a><a href=\"https:\/\/is.ijs.si\/wp-content\/uploads\/2024\/10\/SCAI_2024_paper_6961-1.pdf\" class=\"wp-block-file__button wp-element-button\" download aria-describedby=\"wp-block-file--media-8884f314-e899-44fe-9ccd-6e10f3dea0cf\">Download<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":29,"featured_media":24966,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[105,102],"tags":[],"class_list":["post-16801","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-doi-skui-2024","category-papers"],"_links":{"self":[{"href":"https:\/\/is.ijs.si\/index.php?rest_route=\/wp\/v2\/posts\/16801","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/is.ijs.si\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/is.ijs.si\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/is.ijs.si\/index.php?rest_route=\/wp\/v2\/users\/29"}],"replies":[{"embeddable":true,"href":"https:\/\/is.ijs.si\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=16801"}],"version-history":[{"count":1,"href":"https:\/\/is.ijs.si\/index.php?rest_route=\/wp\/v2\/posts\/16801\/revisions"}],"predecessor-version":[{"id":16803,"href":"https:\/\/is.ijs.si\/index.php?rest_route=\/wp\/v2\/posts\/16801\/revisions\/16803"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/is.ijs.si\/index.php?rest_route=\/wp\/v2\/media\/24966"}],"wp:attachment":[{"href":"https:\/\/is.ijs.si\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=16801"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/is.ijs.si\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=16801"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/is.ijs.si\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=16801"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
