To drive health behavior changes, wearable devices are needed, and they must not only provide accurate sensing and visualization functions but also effective intervention functions. In this paper, we propose a health support system, WaistonBelt X, that consists of a belt-type wearable device with sensing and intervention functions and a smartphone application. WaistonBelt X can automatically measure a waistline with a magnetometer that detects the movements of a blade installed in the buckle, and monitor the basic activities of daily living with inertial sensors. Furthermore, WaistonBelt X intervenes with the user to correct lifestyle habits by using a built-in vibrator. Through evaluation experiments, we confirmed that our proposed device achieves measurement of the circumference on the belt position (mean absolute error of 0.93 cm) and basic activity recognition (F1 score of 0.95) with high accuracy. In addition, we confirmed that the intervention via belt vibration effectively improves the sitting posture of the user.<\/jats:p>","DOI":"10.3390\/s19204600","type":"journal-article","created":{"date-parts":[[2019,10,23]],"date-time":"2019-10-23T11:46:59Z","timestamp":1571831219000},"page":"4600","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["WaistonBelt X: A Belt-Type Wearable Device with Sensing and Intervention Toward Health Behavior Change"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8834-5323","authenticated-orcid":false,"given":"Yugo","family":"Nakamura","sequence":"first","affiliation":[{"name":"Graduate School of Information Science, Nara Institute of Science and Technology, Nara 630-0192, Japan"},{"name":"Research Fellowship for Young Scientists of Japan Society for the Promotion of Science, Tokyo 102-0083, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3135-4915","authenticated-orcid":false,"given":"Yuki","family":"Matsuda","sequence":"additional","affiliation":[{"name":"Graduate School of Science and Technology, Nara Institute of Science and Technology, Nara 630-0192, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7156-9160","authenticated-orcid":false,"given":"Yutaka","family":"Arakawa","sequence":"additional","affiliation":[{"name":"Graduate School and Faculty of Information Science and Electrical Engineering, Kyushu University, Fukuoka 819-0395, Japan"},{"name":"JST Presto, Tokyo 102-0076, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1579-3237","authenticated-orcid":false,"given":"Keiichi","family":"Yasumoto","sequence":"additional","affiliation":[{"name":"Graduate School of Science and Technology, Nara Institute of Science and Technology, Nara 630-0192, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,10,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"S38","DOI":"10.1016\/j.ypmed.2011.11.012","article-title":"A global view on the development of non communicable diseases","volume":"54","author":"Wagner","year":"2012","journal-title":"Prev.
