At the TH Ingolstadt, my team (three fellow students) and I enhanced an automotive infotainment system used in an international study on user experience and trust. Our goal was to create a user-friendly interaction concept with an appealing UI. We combined heuristic reviews with empirical user studies, applying method triangulation with standardized questionnaires, observation, think-aloud protocols, and semi-structured interviews. Based on the results, we developed design variants following Mercedes, Renault, Google, and Tesla guidelines, improving usability for real-world scenarios.

UCD PROCESS
We began with hand-drawn low-fidelity wireframes, evolving them into a clickable prototype and clear information architecture. Early formative evaluations guided iterative usability improvements. High-fidelity screen designs produced the final prototype, tested in a summative evaluation. Findings were compiled in a comprehensive report. The focus was always on intuitive usability while driving, supported by swipe gestures and shortcut buttons.
