78 | Chapter 4 Results (Re)design of the user ‐ interface Definition phase From the 53 characteristics, 31 were prioritized as critical based on the MoSCoW model. Five of these characteristics were related to the algorithm of the activity tracker. The remaining 26 characteristics were related to the user ‐ interface and used in de development and delivery phases (Appendix 4.1). Development and delivery phase Participants The participants ’ demographic characteristics are presented in Table 4.1.

Zero representing no knowledge and 10 a lot of knowledge. The main features of the development and delivery phase are presented in Table 4.2. These findings combined resulted in the MISS activity tracker (Box 4.2). Evaluating usage and experiences in daily life Participants The demographic characteristics of the participants are presented in Table 4.3. Two participants dropped out (n=2: participant ’ s smartphone was too outdated to run the MISS activity app and one due to illness).
