A Wee Bit More Interaction - Designing and Evaluating an Overactive Bladder App.

Overactive Bladder (OAB) is a widespread condition, affecting 20% of the population. Even though it is a treatable condition, people often do not seek treatment. In this paper, we describe how we co-designed and evaluated with 30 stakeholders (9 medical professionals and 21 end-users) an OAB mobile health application that aims to increase adherence to self-managed treatment. Our results support previous research that visualizing progress, setting goals, receiving reminders and feedback increases use. We discovered that games could be used successfully as a distraction technique for urge suppression. Contrary to the current research direction, automatically calculated features could be a detriment to app interaction. Regarding evaluation, we found that designers may not want to rely only on questionnaires when assessing the success of a game and its emotional impact on users.
