It consists of a vision-based method for real-time assessment of the user\u2019s body pose to provide visual feedback as interactive guidance during stretching exercises. Our method compares the users\u2019 actual pose with a pre-trained target pose to assess the quality of stretching for a number of different exercises. We utilize angular and spatial pose features to perform this comparison for each individual exercise. The result of this pose assessment is presented to the user as real-time visual feedback on an \"augmented mirror\" display. As our method relies simply on a single RGB camera, it can be easily utilized in everyday training scenarios. We validate our method in a user study, comparing users\u2019 performance and motivation in stretching when receiving audio-visual guidance on a TV screen both with and without our live feedback. While participants performed equally well in both conditions, feedback boosted their motivation to perform the exercises, highlighting its potential for increasing users\u2019 well-being. Moreover, our results suggest that participants preferred stretching exercises with our live feedback over the condition without the feedback. Finally, an expert evaluation with professional physiotherapists reveals that further work must target improvements of the feedback to ensure correct guidance during stretching.\n<\/jats:p>","DOI":"10.1007\/s00371-024-03450-y","type":"journal-article","created":{"date-parts":[[2024,5,28]],"date-time":"2024-05-28T22:01:43Z","timestamp":1716933703000},"page":"1555-1571","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Offistretch: camera-based real-time feedback for daily stretching exercises"],"prefix":"10.1007","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4560-1726","authenticated-orcid":false,"given":"Jind\u0159ich","family":"Adolf","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7437-9955","authenticated-orcid":false,"given":"Peter","family":"K\u00e1n","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9922-5538","authenticated-orcid":false,"given":"Tiare","family":"Feuchtner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8373-2589","authenticated-orcid":false,"given":"Barbora","family":"Adolfov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2109-8118","authenticated-orcid":false,"given":"Jarom\u00edr","family":"Dole\u017eal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0742-5645","authenticated-orcid":false,"given":"Lenka","family":"Lhotsk\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,5,28]]},"reference":[{"issue":"2","key":"3450_CR1","first-page":"319","volume":"71","author":"SE Kotowski","year":"2022","unstructured":"Kotowski, S.E., Davis, K.G., Gerding, T.: Almost a year in: Virtual offices remained an ergonomic trouble spot.
