Sensor-controlled digital games (SCDGs) integrates data from behavior-tracking sensors to trigger progress, rewards, content, and positive feedback in a digital game to motivate real-time behaviors.<\/jats:p><jats:p>\n          Objectives\u2003To assess the usability of an SCDG prototype over a week of game-playing among 10 older adults with HF in their homes.<\/jats:p><jats:p>\n          Methods\u2003During initial play, participants' SCDG experiences were observed in their homes using a checklist based on the seven-item Serious Game User Evaluator (SeGUE) instrument. After a week of game-playing, participants completed a survey guided by the Intrinsic Motivation Inventory, to provide their perceptions of the SCDG's usability. Qualitative analysis via semistructured interview-derived themes on experiences playing the SCDG, perceptions regarding engaging with the SCDG, and any usability issues encountered.<\/jats:p><jats:p>\n          Results\u2003Ten HF participants (50% women and 50% White) played the SCDG for an average of 6 out of 7 days. Nine found the SCDG to be interesting, satisfying, and easy to play. The average step count over a week was 4,117 steps (range: 967\u20139,892). Average adherence with weight monitoring was 5.9 days in a week. Qualitative analysis yielded outcomes regarding attitudes toward SCDG, and barriers and facilitators that influenced participants' engagement with the SCDG.<\/jats:p><jats:p>\n          Conclusion\u2003To the best of the authors' knowledge, this usability and feasibility study is the first to report an SCDG designed to improve HF self-management behaviors of older adults in their homes. Future research should consider several issues, such as user profiles, prior game-playing experiences, and network conditions most suitable for connected health interventions for older adults living in the community.<\/jats:p>","DOI":"10.1055\/s-0040-1721399","type":"journal-article","created":{"date-parts":[[2020,12,31]],"date-time":"2020-12-31T00:09:55Z","timestamp":1609373395000},"page":"873-881","source":"Crossref","is-referenced-by-count":14,"title":["Usability Testing of a Sensor-Controlled Digital Game to Engage Older Adults with Heart Failure in Physical Activity and Weight Monitoring"],"prefix":"10.1055","volume":"11","author":[{"given":"Kavita","family":"Radhakrishnan","sequence":"additional","affiliation":[{"name":"School of Nursing, The University of Texas, Austin, Texas, United States"}]},{"given":"Christine","family":"Julien","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Cockrell School of Engineering, The University of Texas, Austin, Texas, United States"}]},{"given":"Matthew","family":"O'Hair","sequence":"additional","affiliation":[{"name":"Owner and Game Developer, Good Life Games, Inc., Austin, Texas, United States"}]},{"given":"Thomas","family":"Baranowski","sequence":"additional","affiliation":[{"name":"Distinguished Emeritus Professor Pediatrics, Baylor College of Medicine, Houston, Texas, United States"}]},{"given":"Grace","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Cockrell School of Engineering, The University of Texas, Austin, Texas, United States"}]},{"given":"Catherine","family":"Allen","sequence":"additional","affiliation":[{"name":"School of Nursing, The University of Texas, Austin, Texas, United States"}]},{"given":"Atami","family":"Sagna","sequence":"additional","affiliation":[{"name":"School of Nursing, The University of Texas, Austin, Texas, United States"}]},{"given":"Edison","family":"Thomaz","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Cockrell School of Engineering, The University of Texas, Austin, Texas, United States"}]},{"given":"Miyong","family":"Kim","sequence":"additional","affiliation":[{"name":"School of Nursing, The University of Texas, Austin, Texas, United States"}]}],"member":"194","published-online":{"date-parts":[[2020,12,30]]},"reference":[{"issue":"10","key":"ref1","doi-asserted-by":"crossref","first-page":"e146","DOI":"10.1161\/CIR.0000000000000485","article-title":"Heart disease and stroke statistics\u20142017 Update: a report from the American Heart Association","volume":"135","author":"E J Benjamin","year":"2017","journal-title":"Circulation"},{"issue":"108","key":"ref2","first-page":"1","article-title":"Hospitalization for congestive heart failure: United States, 2000-2010","volume":"108","author":"M J Hall","year":"2012","journal-title":"NCHS Data Brief"},{"issue":"12","key":"ref3","doi-asserted-by":"crossref","first-page":"1189","DOI":"10.1161\/CIRCULATIONAHA.115.018006","article-title":"Do self-management interventions work in patients with heart failure?
