Quantified Self

The Sorcerer’s Apprentice of the “Connected Me”


Camille Gicquel, Pierre Guyot


The Body: this new digital space


Digitalization crosses a new frontier: that of our body. This is what is called the Quantified Self, which is principally based on the use of connected body sensors and Mobile applications. In short, Quantified Self is self-knowledge through self-tracking with technology. The followers of this new practice are becoming more and more numerous. They measure, share and compare their relative physical, nutritional, sleep, health and even intellectual, sexual or mood data: “Self-tracking”, “auto-analytics”, “body hacking”, “self-quantifying”, “self-surveillance”, “Personal Informatics”… Can this Quantified Self transform our lives? Isn’t it likely to provoke stress by prescribing norms and standards of behaviour? How to ensure the proper use of personal data generated by these sensors? This account takes stock of the Quantified Self and its challenges. It provides answers to all the questions raised by this practice: economic models, legal aspects, increasing exposure of privacy and intimacy, a new approach to health management, etc. It shows that if this method of self-knowledge is predictive of the connected intelligent products revolution, it also reveals a new way to understand our relationship to personal data.
