What is good User Experience? How do we measure it? How do we quantify it? User Experience is not only about "getting the job done". User Experience is about guiding and supporting the user, leading them to a subjective end goal. It’s about creating pleasant experiences and journeys. It’s about creating emotional and affective bonds, while the user interacts with services or product. We need ways of implementing user experience in health care to address the challenges of a lack of clinical resources. Inspired by the 4Ps of medicine, this thesis tries to address the participatory and personalized perspective. A UX framework, named data-driven UX is proposed to highlight how patientgenerated data creates value in a clinical workflow. The framework highlights how UX methodology and tools can be applied to a health care domain, hearing health care. Hypotheses are validated early, frequently and iterative through rapid prototyping. Hearing aids are treated as contextual aware devices that collect data. The contextual data shows that individuals have unique behavioral patterns related to program and volume interactions. These individual nuances are not taken into account with the current hearing aid fitting paradigm. It is also shown that individual behavior can be modeled from contextual parameters, including acoustic environments, location, and motion. This data can be used to personalize hearing aids of the future. Using the data actively in clinical sessions, to debrief patients, help with recall and to highlight behavioral traits, addressing participatory health care. To engage the patient, the interface to the medical device must be compelling. Thoughts on designing compelling interfaces, by addressing mental models, and using metaphors and microinteraction. In the end, some considerations of the future of hearing healthcare are proposed.
