As icon incar we worked together with German OEM and sustainability startup Sono Motors to create an intuitive and scalable User Interface for the Sion - Sono Motors' own mid-sized electric vehicle. The Sion is a passenger vehicle with integrated solar panels on all exterior sides which could self sustain a substantial portion of its' power needs. The goal of the project was to create an easy-to-use and modern looking interface. My task within this project was to create the interaction concept from scratch - with wireframes, user journeys and personas, interaction models and specifications. I also conducted many user tests and created several software prototypes to enable a tangible and desirable solution.
