Applying a user-centered, rapid-prototyping methodology with quantified self: A case study with triathletes

This workshop paper discusses how we applied a user-centered, rapid-prototyping methodology to design and evaluate a Quantified Self dashboard for triathletes. Quantified Self barriers as discussed by Li and Forlizzi [1] and Choe et al. [2] are taken into account. A dashboard is designed for and evaluated with in total 25 triathletes and fourteen regular persons. Our results confirm that this methodology is successful and a well designed dashboard can be used to help users analyze their own data.
