However, intricate machine learning and deep learning algorithms often lead to the development of \u201cblack box\u201d models, which lack transparency and comprehensibility for medical professionals and end users. In this context, the integration of explainable artificial intelligence (XAI) has emerged as a crucial solution. By providing insights into the inner workings of complex algorithms, XAI aims to foster trust and empower stakeholders to use wearable technologies responsibly.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This paper aims to review the recent literature and explore the application of explainability in wearables. By examining how XAI can enhance the interpretability of generated data and models, this review sought to shed light on the possibilities that arise at the intersection of wearable technologies and XAI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We collected publications from ACM Digital Library, IEEE Xplore, PubMed, SpringerLink, JMIR, Nature, and Scopus. The eligible studies included technology-based research involving wearable devices, sensors, or mobile phones focused on explainability, machine learning, or deep learning and that used quantified self data in medical contexts. Only peer-reviewed articles, proceedings, or book chapters published in English between 2018 and 2022 were considered. We excluded duplicates, reviews, books, workshops, courses, tutorials, and talks. We analyzed 25 research papers to gain insights into the current state of explainability in wearables in the health care context.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Our findings revealed that wrist-worn wearables such as Fitbit and Empatica E4 are prevalent in health care applications. However, more emphasis must be placed on making the data generated by these devices explainable. Among various explainability methods, post hoc approaches stand out, with Shapley Additive Explanations as a prominent choice due to its adaptability. The outputs of explainability methods are commonly presented visually, often in the form of graphs or user-friendly reports. Nevertheless, our review highlights a limitation in user evaluation and underscores the importance of involving users in the development process.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The integration of XAI into wearable health care technologies is crucial to address the issue of black box models. While wrist-worn wearables are widespread, there is a notable gap in making the data they generate explainable. Post hoc methods such as Shapley Additive Explanations have gained traction for their adaptability in explaining complex algorithms visually. However, user evaluation remains an area in which improvement is needed, and involving users in the development process can contribute to more transparent and reliable artificial intelligence models in health care applications. Further research in this area is essential to enhance the transparency and trustworthiness of artificial intelligence models used in wearable health care technology.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2196\/53863","type":"journal-article","created":{"date-parts":[[2024,12,24]],"date-time":"2024-12-24T10:30:32Z","timestamp":1735036232000},"page":"e53863","source":"Crossref","is-referenced-by-count":41,"title":["Exploring the Applications of Explainability in Wearable Data Analytics: Systematic Literature Review"],"prefix":"10.2196","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4250-945X","authenticated-orcid":false,"given":"Yasmin","family":"Abdelaal","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6321-5242","authenticated-orcid":false,"given":"Micha\u00ebl","family":"Aupetit","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8742-5519","authenticated-orcid":false,"given":"Abdelkader","family":"Baggag","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1474-2692","authenticated-orcid":false,"given":"Dena","family":"Al-Thani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2024,12,24]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1177\/0141076816663560"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1177\/19322968221103561"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1109\/access.2020.2971576"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.knosys.2023.110273"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1109\/access.2018.2870052"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.3390\/electronics12051092"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1109\/tse.1985.231882"},{"key":"ref8","unstructured":"USACM issues statement on algorithmic transparency and accountabilityAssociation for Computing Machinery20172024-04-29https:\/\/www.acm.org\/articles\/bulletins\/2017\/january\/usacm-statement-algorithmic-accountability"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1609\/aimag.v40i2.2850"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/j.cmpb.2022.107161"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/j.patcog.2021.108102"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1145\/3485275"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.dajour.2023.100230"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.5465\/annals.2018.0057"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1109\/ichi.2018.00095"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.3390\/app12031353"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1109\/access.2023.3285596"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1007\/978-981-99-3177-4_42"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1109\/ojcoms.2022.3215676"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.2196\/18907"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.3390\/s21165589"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.3390\/s23041959"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.3390\/math10121990"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1145\/3236009"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbi.2020.103655"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1145\/3583558"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.3390\/make3030032"},{"key":"ref28","unstructured":"LundbergSMLeeSIA unified approach to interpreting model predictionsProceedings of the 31st International Conference on Neural Information Processing Systems2017NIPS '17December 4-9, 2017Long Beach, CA476877"},{"key":"ref29","unstructured":"ClosJWiratungaNMassieSTowards explainable text classification by jointly learning lexicon and modifier termsSemantic Scholar2024-09-25https:\/\/www.semanticscholar.org\/paper\/Towards-Explainable-Text-Classification-by-Jointly-Clos-Wiratunga\/ca68496cb928636b8d735b4b3ad864daad50d386"},{"key":"ref30","author":"Das, A","year":"2020","journal-title":"arXiv.
