Through an iterative design process of four iterations and a longitudinal user test of six weeks, we created LOOP. The starting point of LOOP was frictional feedback and physicalisation of you and your running mate's training activities, without taking intensity and distance into account. We deployed loop in a house where multiple people lived together. Users were provided with diaries and we exectuded a semi-structured interview afterwards to evaluate the concept.This revealed the prototype increased awareness but no increasement in activity level was noted. The third iteration focused running mates who lived apart from each other. This resulted in a connected prototype which was presented on DemoDay.
The fourth iteration focused on improvement of the design and provided suggestions for future work. No prototype was developed.
