Computer storage has become significantly cheaper, and advancements in sensing technology allows for the efficient sensing of personal activities, locations and the environment. This is best seen in the growing popularity of the quantified self movement, in which life activities are tracked using wearable sensors in the hope of better understanding human performance in a variety of tasks. This review aims to provide a comprehensive summary of lifelogging, to cover its research history, current technologies, and applications. Thus far, most of the lifelogging research has focused predominantly on visual lifelogging, hence we maintain this focus in this review. However, we also reflect on the challenges lifelogging poses for information access and retrieval in general. This review is a suitable reference for those seeking an information retrieval scientist\u2019s perspective on lifelogging and the quantified self.<\/jats:p>","DOI":"10.1561\/1500000033","type":"journal-article","created":{"date-parts":[[2014,6,16]],"date-time":"2014-06-16T09:57:10Z","timestamp":1402912630000},"page":"1-125","source":"Crossref","is-referenced-by-count":351,"title":["LifeLogging: Personal Big Data"],"prefix":"10.1108","volume":"8","author":[{"given":"Cathal","family":"Gurrin","sequence":"first","affiliation":[{"name":"Insight Centre for Data Analytics Dublin City University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan F.","family":"Smeaton","sequence":"additional","affiliation":[{"name":"Insight Centre for Data Analytics Dublin City University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aiden R.","family":"Doherty","sequence":"additional","affiliation":[{"name":"Nuffield Department of Population Health University of Oxford"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"140","published-online":{"date-parts":[[2014,6,16]]},"reference":[{"key":"2026040314245294300_ref001","article-title":"Development of a life logging system via depth imaging-based human activity recognition for smart homes","volume-title":"SHB2012 - 8th International Symposium on Sustainable Healthy Buildings","author":"Jalal","year":"2012"},{"key":"2026040314245294300_ref002","first-page":"10","article-title":"Digitizing Personal Experiences: Capture and Retrieval of Life Log","volume-title":"Proceedings of the 11th International Multimedia Model ling Conference, 2005.
