We introduce a tagless indoor person localization system based on capacitive sensing and localization algorithms that can determine the location with less than 0.2 m average error in a 3 m \u00d7 3 m room and has recall and precision better than 70%. We also discuss the effects of various noise types on the measurements and ways to reduce them using filters suitable for on-sensor implementation to lower communication energy consumption. We also compare the performance of several standard localization algorithms in terms of localization error, recall, precision, and accuracy of detection of the movement trajectory.<\/jats:p>","DOI":"10.3390\/s16091448","type":"journal-article","created":{"date-parts":[[2016,9,7]],"date-time":"2016-09-07T09:59:46Z","timestamp":1473242386000},"page":"1448","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["A Tagless Indoor Localization System Based on Capacitive Sensing Technology"],"prefix":"10.3390","volume":"16","author":[{"given":"Alireza","family":"Ramezani Akhmareh","sequence":"first","affiliation":[{"name":"Politecnico di Torino, Corso Duca degli Abruzzi, Torino 24-10129, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0884-5158","authenticated-orcid":false,"given":"Mihai","family":"Lazarescu","sequence":"additional","affiliation":[{"name":"Politecnico di Torino, Corso Duca degli Abruzzi, Torino 24-10129, Italy"}]},{"given":"Osama","family":"Bin Tariq","sequence":"additional","affiliation":[{"name":"Politecnico di Torino, Corso Duca degli Abruzzi, Torino 24-10129, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9762-6522","authenticated-orcid":false,"given":"Luciano","family":"Lavagno","sequence":"additional","affiliation":[{"name":"Politecnico di Torino, Corso Duca degli Abruzzi, Torino 24-10129, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2016,9,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"71","DOI":"10.14257\/ijsh.2014.8.1.09","article-title":"A review on device-free passive indoor positioning methods","volume":"8","author":"Vuorela","year":"2014","journal-title":"Int.
