How annotated visualizations in self-care technology supported a stroke survivor in goal setting and reflection

Self-management in health contexts requires patients to manage their own goal setting. Time series visualizations improve understanding of time-oriented data. But how they and interactions with them can support reflection and goal setting in selfmanagement is poorly understood. We compare findings from interviews with a health care professional and three stroke survivors on goal setting and reflection in a clinical setting with insights from a field study with one of the stroke survivors using a tablet application for self-care. Free text annotations of point plot score visualizations supported reflection but not long-term goal setting. The paper contributes a set of design guidelines for systems supporting people in their motivation and reflection in their self-rehabilitation.
