We introduce ProxiFit, a highly practical on-device exercise monitoring system capable of classifying and counting exercises even if the device stays still. Utilizing novel proximity sensing of natural magnetism in exercise equipment, ProxiFit brings (1) a new category of exercise not involving device motion such as lower-body machine exercise, and (2) a new off-body exercise monitoring mode where a smartphone can be conveniently viewed in front of the user during workouts. ProxiFit addresses common issues of faint magnetic sensing by choosing appropriate preprocessing, negating adversarial motion artifacts, and designing a lightweight yet noise-tolerant classifier. Also, application-specific challenges such as a wide variety of equipment and the impracticality of obtaining large datasets are overcome by devising a unique yet challenging training policy. We evaluate ProxiFit on up to 10 weight machines (5 lower- and 5 upper-body) and 4 free-weight exercises, on both wearable and signage mode, with 19 users, at 3 gyms, over 14 months, and verify robustness against user and weather variations, spatial and rotational device location deviations, and neighboring machine interference.<\/jats:p>","DOI":"10.1145\/3610920","type":"journal-article","created":{"date-parts":[[2023,9,27]],"date-time":"2023-09-27T19:45:03Z","timestamp":1695843903000},"page":"1-32","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["ProxiFit"],"prefix":"10.1145","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-9270-2692","authenticated-orcid":false,"given":"Jiha","family":"Kim","sequence":"first","affiliation":[{"name":"POSTECH, Pohang, Gyeongbuk, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-2021-5647","authenticated-orcid":false,"given":"Younho","family":"Nam","sequence":"additional","affiliation":[{"name":"POSTECH, Pohang, Gyeongbuk, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3957-3469","authenticated-orcid":false,"given":"Jungeun","family":"Lee","sequence":"additional","affiliation":[{"name":"POSTECH, Pohang, Gyeongbuk, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3957-3469","authenticated-orcid":false,"given":"Young-Joo","family":"Suh","sequence":"additional","affiliation":[{"name":"POSTECH, Pohang, Gyeongbuk, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7370-3944","authenticated-orcid":false,"given":"Inseok","family":"Hwang","sequence":"additional","affiliation":[{"name":"POSTECH, Pohang, Gyeongbuk, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2023,9,27]]},"reference":[{"key":"e_1_2_2_1_1","volume-title":"Wearable Tech is New Top Fitness Trend for","year":"2019","unstructured":"2018.
