The e-VITA project, which receives funding from both the European Union and Japan, is built on a cutting edge method of virtual coaching that focuses on the key areas of active and healthy aging. The requirements for the virtual coach were ascertained through a process of participatory design in workshops, focus groups, and living laboratories in Germany, France, Italy, and Japan. Several use cases were then chosen for development utilising the open-source Rasa framework. The system uses common representations such as Knowledge Bases and Knowledge Graphs to enable the integration of context, subject expertise, and multimodal data, and is available in English, German, French, Italian, and Japanese.<\/jats:p>","DOI":"10.3390\/s23052748","type":"journal-article","created":{"date-parts":[[2023,3,3]],"date-time":"2023-03-03T02:03:08Z","timestamp":1677808988000},"page":"2748","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Interaction with a Virtual Coach for Active and Healthy Ageing"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9883-7500","authenticated-orcid":false,"given":"Michael","family":"McTear","sequence":"first","affiliation":[{"name":"School of Computing, Ulster University, Belfast BT15 1AP, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1229-239X","authenticated-orcid":false,"given":"Kristiina","family":"Jokinen","sequence":"additional","affiliation":[{"name":"Artificial Intelligence Research Center, National Institute of Advanced Industrial Science and Technology (AIRC\/AIST), Tokyo 135-0064, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mirza Mohtashim","family":"Alam","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Angewandte Informatik (INFAI), 04109 Leipzig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qasid","family":"Saleem","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Angewandte Informatik (INFAI), 04109 Leipzig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6842-7575","authenticated-orcid":false,"given":"Giulio","family":"Napolitano","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Angewandte Informatik (INFAI), 04109 Leipzig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7572-0860","authenticated-orcid":false,"given":"Florian","family":"Szczepaniak","sequence":"additional","affiliation":[{"name":"Institut Mines-T\u00e9l\u00e9com (IMT), 91120 Palaiseau, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1085-6104","authenticated-orcid":false,"given":"Mossaab","family":"Hariz","sequence":"additional","affiliation":[{"name":"Institut Mines-T\u00e9l\u00e9com (IMT), 91120 Palaiseau, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G\u00e9rard","family":"Chollet","sequence":"additional","affiliation":[{"name":"Institut Mines-T\u00e9l\u00e9com (IMT), 91120 Palaiseau, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0655-2880","authenticated-orcid":false,"given":"Christophe","family":"Lohr","sequence":"additional","affiliation":[{"name":"Institut Mines-T\u00e9l\u00e9com (IMT), 91120 Palaiseau, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00e9r\u00f4me","family":"Boudy","sequence":"additional","affiliation":[{"name":"Institut Mines-T\u00e9l\u00e9com (IMT), 91120 Palaiseau, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5072-3264","authenticated-orcid":false,"given":"Zohre","family":"Azimi","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Experimentelle Psychophysiologie Gmbh (IXP), 40215 D\u00fcsseldorf, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sonja Dana","family":"Roelen","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Experimentelle Psychophysiologie Gmbh (IXP), 40215 D\u00fcsseldorf, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rainer","family":"Wieching","sequence":"additional","affiliation":[{"name":"Chair for Business Information Systems and New Media, Faculty III, Universit\u00e4t Siegen (USI), 57068 Siegen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,2]]},"reference":[{"key":"ref_1","unstructured":"Spasova, S., Baeten, R., Coster, S., Ghailani, D., Pe\u00f1a-Casas, R., and Vanhercke, B.
