Unobtrusive data collection in a smart home environment can monitor and assess elderly residents\u2019 health state based on changes in their mobility patterns. In this paper, a smart home system testbed setup for a solo-resident house is discussed and evaluated. We use paired Passive infra-red (PIR) sensors at each entry of a house and capture the resident\u2019s activities to model mobility patterns. We present the required testbed implementation phases, i.e., deployment, post-deployment analysis, re-deployment, and conduct behavioural data analysis to highlight the usability of collected data from a smart home. The main contribution of this work is to apply intelligence from a post-deployment process mining technique (namely, the parallel activity log inference algorithm (PALIA)) to find the best configuration for data collection in order to minimise the errors. Based on the post-deployment analysis, a re-deployment phase is performed, and results show the improvement of collected data accuracy in re-deployment phase from 81.57% to 95.53%. To complete our analysis, we apply the well-known CASAS project dataset as a reference to conduct a comparison with our collected results which shows a similar pattern. The collected data further is processed to use the level of activity of the solo-resident for a behaviour assessment.<\/jats:p>","DOI":"10.3390\/s20247167","type":"journal-article","created":{"date-parts":[[2020,12,14]],"date-time":"2020-12-14T21:25:08Z","timestamp":1607981108000},"page":"7167","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Design and Evaluation of a Solo-Resident Smart Home Testbed for Mobility Pattern Monitoring and Behavioural Assessment"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0584-4360","authenticated-orcid":false,"given":"Mohsen","family":"Shirali","sequence":"first","affiliation":[{"name":"Computer Science and Engineering, Shahid Beheshti University, Tehran 19839-63113, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2602-6367","authenticated-orcid":false,"given":"Jose-Luis","family":"Bayo-Monton","sequence":"additional","affiliation":[{"name":"Process Mining 4 Health Lab\u2013SABIEN-ITACA Institute, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2819-5597","authenticated-orcid":false,"given":"Carlos","family":"Fernandez-Llatas","sequence":"additional","affiliation":[{"name":"Process Mining 4 Health Lab\u2013SABIEN-ITACA Institute, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"},{"name":"Department of Clinical Sciences, Intervention and Technology (CLINTEC), Karolinska Institutet, 17177 Stockholm, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mona","family":"Ghassemian","sequence":"additional","affiliation":[{"name":"BT Applied Research Labs, Adastral Park, Ipswich IP5 3RE, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1806-8575","authenticated-orcid":false,"given":"Vicente","family":"Traver Salcedo","sequence":"additional","affiliation":[{"name":"Process Mining 4 Health Lab\u2013SABIEN-ITACA Institute, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"543","DOI":"10.1038\/35087589","article-title":"The end of world population growth","volume":"412","author":"Lutz","year":"2001","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Lutz, W.
