Engineering automotive HMIs that are optimized for correct and fast perception.

Automotive HMI design is driven by systematic model-based user engineering methods focusing on traceability and functional validation. User-centered design processes can open up the design space to discover new creative design solutions whereas model-based engineering methods offer a rigorous design derivation process. We present Konect, a user-centered design derivation process that fosters creativity and also ensures a systematic design derivation to end up with new interface designs that are optimized for correct and fast readability. Five Human Factor Experts applied the method and ended up with 5 creative and very different design results. In a follow-up experiment with 33 car drivers, we figured out that all designs could be perceived faster and more frequently correct than automotive interfaces for the same assistant system that have been designed with other design methods.
