On the Integration of Self-tracking Data amongst Quantified Self Members

representations were depictions of selftracking data where the relationship between the data and its representation were not obvious to the viewer. As illustrated in the findings, these representations took inspiration from the visual arts. They were forms of self-expression, as illustrated in Tomasz’ visualisation of skateboarding. Furthermore, these representations were made deliberately ambiguous. Abstract representations may seem counterintuitive in the context of Quantified Self, because as illustrated so far, a key aim in quantifying health and lifestyle information is to provide unambiguous feedback for reflection and self-improvement. However, as is well known in HCI (Gaver et al. 2003), the ambiguity of representations can also be seen as a strength because it can encourage close personal engagement with and reflection on the data. 5.3. Data Representations and Reflection The last contribution of this work is to extend our current understanding of different forms of representation and the opportunities they offer for subsequent reflection. As discussed above, abstract representations were deliberately ambiguous, which encouraged close personal engagement with the
