    Koi

    An educative tool empowering children with type 1 diabetes






    In remote northern Sweden, children with diabetes struggle to get regular care — and when they do, they're passive patients waiting to be treated. Koi is a system that gives kids more control: a plush companion that reads their glucose sensor through a hug, a board game that turns diabetes education into play, and a nurse platform for remote monitoring

    Role: Fuzzy front end, design ethnography, interviews, journey mapping, logo and visual language, workshop facilitation, concept validation
    Collaborators: Nordic Welfare Center and Region Västerbotten
    Impact: Exhibited at World Expo Dubai. Core77 Design Awards 2022 Notable
