Utilising the Ubiquity of the Cell Phone to Record Physiological Activities


April 23, 2009


Lifelogging is a term used to describe recording different aspects of your daily life, in digital form, for your own exclusive personal use. It is a form of reverse surveillance, sometimes termed sousveillance, referring to us – the subjects – doing the watching, of ourselves. In today’s healthcare world where we react to conditions that have already developed, lifelogging technologies may offer a glimpse into a future world of proactive healthcare where symptoms of conditions are detected at much earlier stages.

At the end of last year it was estimated that there were 4 billion cell phones in the world, in comparison to just over 1 billon PCs. In this presentation I will discuss a framework, which leverages the ubiquity of the cell phone, to aggregate multiple wearable biological sensors. This physiological lifelogged data can then be easily queried via an interface which utilises contextual memory retrieval cues to assist people remember what type of activity they were doing at a particular time. This may be helpful for the diagnosis of potential medical conditions e.g. to explain that my heart rate was very high because I was at the gym, or that I had a disturbed night’s sleep because I was in an unfamiliar hotel room.

Aiden Doherty is a postdoctoral researcher in CLARITY: Centre for Sensor Web Technologies. His research interests cover lifelogging, sports & personal health IT applications, location aware computing, and multimedia information management/retrieval. He has approximately 15 publications, has given 5 seminar talks and is just finishing a three month internship in MSR. He has also distributed a lifelogging browsing system to over 10 universities to enable the field proceed more efficiently. Recently Aiden obtained his PhD from Dublin City University where he was a government of Ireland research scholar.
