In an agile development process we faced the problem of visualizing sound input and output to show the users' hearing ability, as well as to show the potential of the support of a hearing aid. Because hearing disability is still a taboo, we wanted to create a positive experience around the possibility of enhanced hearing and the steps to get there. A priority was to also allow the app to let people experience somebody else's hearing to further raise awareness of potential hearing loss.
Based on the results of extensive user research with patients, their families, and doctors, we redefined the value proposition, the service-blueprint and the initial interaction with the service. We designed a new visual metaphor and the touchpoints for Mimi’s product-service-system.
