‘Technologies of the self and other’: how self-tracking technologies also shape the other

Although there is ample literature on the quantified self, considerably less attention is given to how our relation with the other is being shaped by self-tracking technologies that allow data sharing (e.g. wearables or apps such as Strava or RunKeeper). This paper seeks to fill this gap by providing a conceptual framework for discussing ‘technologies of the self and other’, by showing that, in most cases, self-tracking also involves other-tracking. We elaborate on two cases and practical domains to illustrate and discuss this mutual process: first, the quantified workplace and, second, quantification by health apps and wearables in a non-clinical and self-initiated context. We argue that these shapings are never (morally) neutral and have ethical implications
