Previous research reported that colors could affect reading skills as an important factor in the emotional and physiological state of the body. The aim of the study was to assess developmental differences between second and third grade students of an elementary school, and to evaluate differences in electroencephalography (EEG), ocular, electrodermal activities (EDA) and heart rate variability (HRV). Our findings showed a decreasing trend with age regarding EEG power bands (Alpha, Beta, Delta, Theta) and lower scores of reading duration and eye-tracking measures in younger children compared to older children. As shown in the results, HRV parameters showed higher scores in 12 background and overlay colors among second than third grade students, which is linearly correlated to the level of stress and is readable from EDA measures as well. Our study showed the calming effect on second graders of turquoise and blue background colors. Considering other colors separately for each parameter, we assumed that there are no systematic differences in reading duration, EEG power band, eye-tracking and EDA measures.<\/jats:p>","DOI":"10.3390\/s21020406","type":"journal-article","created":{"date-parts":[[2021,1,10]],"date-time":"2021-01-10T23:03:42Z","timestamp":1610319822000},"page":"406","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["The Sensor Hub for Detecting the Developmental Characteristics in Reading in Children on a White vs. Colored Background\/Colored Overlays"],"prefix":"10.3390","volume":"21","author":[{"given":"Tamara","family":"Jakovljevi\u0107","sequence":"first","affiliation":[{"name":"Jo\u017eef Stefan International Postgraduate School, 1000 Ljubljana, Slovenia"}]},{"given":"Milica M.","family":"Jankovi\u0107","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering, University of Belgrade, 11000 Belgrade, Serbia"}]},{"given":"Andrej M.","family":"Savi\u0107","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering, University of Belgrade, 11000 Belgrade, Serbia"}]},{"given":"Ivan","family":"Soldatovi\u0107","sequence":"additional","affiliation":[{"name":"Institute of Medical Statistics and Informatics, Faculty of Medicine, University of Belgrade,11000 Belgrade, Serbia"}]},{"given":"Petar","family":"Todorovi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of Kragujevac, 34000 Kragujevac, Serbia"}]},{"given":"Tadeja","family":"Jere Jakulin","sequence":"additional","affiliation":[{"name":"FT\u0160 Turistica, University of Primorska, 6320 Portoro\u017e, Slovenia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0623-0865","authenticated-orcid":false,"given":"Gregor","family":"Papa","sequence":"additional","affiliation":[{"name":"Computer Systems Department, Jo\u017eef Stefan Institute, 1000 Ljubljana, Slovenia"}]},{"given":"Vanja","family":"Kovi\u0107","sequence":"additional","affiliation":[{"name":"Laboratory for Neurocognition and Applied Cognition, Faculty of philosophy, University of Belgrade, 11000 Belgrade, Serbia"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"500","DOI":"10.1080\/20445911.2015.1046877","article-title":"Developmental eye-tracking research in reading: Introduction to the special issue","volume":"27","author":"Schroeder","year":"2015","journal-title":"J.
