Chronic stress can have a serious long-term impact on our physical as well as our psychological health, due to ongoing increased levels of the chemicals released in the \u2018fight or flight\u2019 response. The currently available stress assessment methods are usually not suitable for daily chronic stress measurement. The paper presents a context-aware chronic stress recognition system that addresses this problem. The proposed system obtains contextual data from various mobile sensors and other external sources in order to calculate the impact of ongoing stress. By identifying and visualizing ongoing stress situations of an individual user, he\/she is able to modify his\/her behavior in order to successfully avoid them. Clinical evaluation of the proposed methodology has been made in parallel by using electrodermal activity sensor. To the best of our knowledge, the system presented herein is the first one that enables recognition of chronic stress situations on the basis of user context.<\/jats:p>","DOI":"10.3390\/s121115888","type":"journal-article","created":{"date-parts":[[2012,11,16]],"date-time":"2012-11-16T11:03:15Z","timestamp":1353063795000},"page":"15888-15906","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["A Presence-Based Context-Aware Chronic Stress Recognition System"],"prefix":"10.3390","volume":"12","author":[{"given":"Klemen","family":"Peternel","sequence":"first","affiliation":[{"name":"Laboratory for Telecommunications, Faculty of Electrical Engineering, University of Ljubljana, Tr\u017ea\u0161ka 25, 1000 Ljubljana, Slovenia"}]},{"given":"Matev\u017e","family":"Poga\u010dnik","sequence":"additional","affiliation":[{"name":"Laboratory for Telecommunications, Faculty of Electrical Engineering, University of Ljubljana, Tr\u017ea\u0161ka 25, 1000 Ljubljana, Slovenia"}]},{"given":"Rudi","family":"Tav\u010dar","sequence":"additional","affiliation":[{"name":"Mirabi Institute, Hrastje 223, 4000 Kranj, Slovenia"}]},{"given":"Andrej","family":"Kos","sequence":"additional","affiliation":[{"name":"Laboratory for Telecommunications, Faculty of Electrical Engineering, University of Ljubljana, Tr\u017ea\u0161ka 25, 1000 Ljubljana, Slovenia"}]}],"member":"1968","published-online":{"date-parts":[[2012,11,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1038\/138032a0","article-title":"A syndrome produced by diverse nocuous agents","volume":"138","author":"Selye","year":"1936","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"17","DOI":"10.1093\/abm\/15.1.17","article-title":"Daily stress and stress-related disorders","volume":"15","author":"Brantley","year":"1993","journal-title":"Ann.
