Gesture recognition based on body-mounted accelerometers has been proposed as a viable solution to translate patterns of movements that are associated with user commands, thus substituting point-and-click methods or other cumbersome input devices. On the other hand, cost and power constraints make the implementation of a natural and efficient interface suitable for consumer applications a critical task. Even though several gesture recognition solutions exist, their use in HCI context has been poorly characterized. For this reason, in this paper, we consider a low-cost\/low-power wearable motion tracking system based on integrated accelerometers called motion capture with accelerometers (MOCA) that we evaluated for navigation in virtual spaces. Recognition is based on a geometric algorithm that enables efficient and robust detection of rotational movements. Our objective is to demonstrate that such a low-cost and a low-power implementation is suitable for HCI applications. To this purpose, we characterized the system from both a quantitative point of view and a qualitative point of view. First, we performed static and dynamic assessment of movement recognition accuracy. Second, we evaluated the effectiveness of user experience using a 3D game application as a test bed.<\/jats:p>","DOI":"10.1155\/2007\/82638","type":"journal-article","created":{"date-parts":[[2007,6,3]],"date-time":"2007-06-03T03:45:28Z","timestamp":1180842328000},"page":"1-11","source":"Crossref","is-referenced-by-count":14,"title":["MOCA: A Low-Power, Low-Cost Motion Capture System Based on Integrated Accelerometers"],"prefix":"10.1155","volume":"2007","author":[{"given":"Elisabetta","family":"Farella","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luca","family":"Benini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bruno","family":"Ricc\u00f2","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Acquaviva","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/MCG.2002.1046626"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1007\/s007790200045"},{"issue":"8","key":"9","first-page":"292","volume":"125","year":"2000"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/JPROC.2003.817122"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1109\/MCG.2002.1046629"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1109\/TNSRE.2004.827825"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1016\/j.medengphy.2004.11.006"}],"container-title":["Advances in Multimedia"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/am\/2007\/082638.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/am\/2007\/082638.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,11]],"date-time":"2016-08-11T13:48:26Z","timestamp":1470923306000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/am\/2007\/082638\/abs\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007]]},"references-count":7,"alternative-id":["082638","82638"],"URL":"https:\/\/doi.org\/10.1155\/2007\/82638","relation":{},"ISSN":["1687-5680","1687-5699"],"issn-type":[{"value":"1687-5680","type":"print"},{"value":"1687-5699","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007]]}}}
