This fact has led the European Union and many countries to propose new policies for caring services directed to this group. The current trend is to promote the care of the elderly in their own homes, thus avoiding inverting resources on residences. With this in mind, there are now new solutions in this direction, which try to make use of the continuous advances in computer science. This paper tries to advance in this area by proposing the use of a personal assistant to help older people at home while carrying out their daily activities. The proposed personal assistant is called ME3CA, and can be described as a cognitive assistant that offers users a personalised exercise plan for their rehabilitation. The system consists of a sensorisation platform along with decision-making algorithms paired with emotion detection models. ME3CA detects the users\u2019 emotions, which are used in the decision-making process allowing for more precise suggestions and an accurate (and unbiased) knowledge about the users\u2019 opinion towards each exercise.<\/jats:p>","DOI":"10.3390\/s20030852","type":"journal-article","created":{"date-parts":[[2020,2,6]],"date-time":"2020-02-06T02:59:18Z","timestamp":1580957958000},"page":"852","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["ME3CA: A Cognitive Assistant for Physical Exercises that Monitors Emotions and the Environment"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1153-0616","authenticated-orcid":false,"given":"Jaime A.","family":"Rincon","sequence":"first","affiliation":[{"name":"Department of Computer Systems and Computation, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6170-4912","authenticated-orcid":false,"given":"Angelo","family":"Costa","sequence":"additional","affiliation":[{"name":"ALGORITMI Center, University of Minho, 4700 Braga, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3549-0754","authenticated-orcid":false,"given":"Paulo","family":"Novais","sequence":"additional","affiliation":[{"name":"ALGORITMI Center, University of Minho, 4700 Braga, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2743-6037","authenticated-orcid":false,"given":"Vicente","family":"Julian","sequence":"additional","affiliation":[{"name":"Department of Computer Systems and Computation, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3649-6530","authenticated-orcid":false,"given":"Carlos","family":"Carrascosa","sequence":"additional","affiliation":[{"name":"Department of Computer Systems and Computation, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,5]]},"reference":[{"key":"ref_1","unstructured":"(2020, February 04).
