The results of the two coding phases provide complementary insights to answer our research question. The emergent themes show key experiential aspects of how this wearable device enables users to digitally track their physical activities through accuracy, wearability, and goal achievement. The remaining themes show the technical aspects of the technology in terms of charging the physical device and aggregating its digital side. While these themes show how this minimalist wearable accomplishes its mediator role, the directed coding based on the affordance framework provides evidence of two sources of failures. The first source comes from failures within affordances with respect to the physical device or the accompanying software. The second source stems from the failed integration across affordances, between instrumental and supplemental, or between specifica ffordances in each category.
