However, an objective and usable method for dietary intake tracking remains unrealized despite numerous efforts by researchers over the last decade. In this work, we present a new wearable computing approach for detecting eating episodes. Using a novel multimodal sensing strategy combining accelerometer and range sensing, the approach centers on a discreet and lightweight instrumented necklace that captures head and jawbone movements without direct contact with the skin. An evaluation of the system with 32 participants comprised of three phases resulted in eating episodes detected with 95.2% precision and 81.9% recall in controlled studies and 78.2% precision and 72.5% recall in the free-living study. This research add technical contributions to the fields of wearable computing, human activity recognition, and mobile health.<\/jats:p>","DOI":"10.1145\/3191736","type":"journal-article","created":{"date-parts":[[2018,3,27]],"date-time":"2018-03-27T12:06:45Z","timestamp":1522152405000},"page":"1-21","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":69,"title":["Detecting Eating Episodes by Tracking Jawbone Movements with a Non-Contact Wearable Sensor"],"prefix":"10.1145","volume":"2","author":[{"given":"Keum San","family":"Chun","sequence":"first","affiliation":[{"name":"University of Texas at Austin, Austin, Texas, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarnab","family":"Bhattacharya","sequence":"additional","affiliation":[{"name":"University of Texas at Austin, Austin, Texas, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edison","family":"Thomaz","sequence":"additional","affiliation":[{"name":"University of Texas at Austin, Austin, Texas, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2018,3,26]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.artmed.2007.11.007"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1109\/MPRV.2009.32"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1371\/annotation\/c313df3a-52bd-4cbe-af14-6676480d1a43"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/NEBEC.2014.6972716"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0892-1997(05)80123-7"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/3130902"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/2802083.2808411"},{"key":"e_1_2_1_9_1","unstructured":"Sheila A Bingham. 1987.
