During the last decade, the number of functions of automotive user interfaces has increased rapidly. Besides traditional controls to drive a car, driver assistance, infotainment, entertainment, and comfort systems need to be controlled while driving. This does not only affect the driver's cognitive workload but also leads to increased complexity in designing automotive user interfaces. In this paper, we provide models and tools for rapid prototyping and the evaluation of user interfaces in this

In contrast, in our approach we use an adapted Keystroke-Level Model (KLM) that is based on empirically collected data for typical operations in the car. It takes into account the aspect of attention switching in the car between primary tasks and other tasks. We present KLM operator times that we determined in a user study as well as a formula for estimating the task completion time. The presented model is the foundation for the MI-AUI prototyping tool that we implemented for permitting the creation of automotive interfaces using tangible controls. By demonstrating a typical operation with the MI-AUI prototype, the estimated task completion time can be calculated. MI-AUI is an evaluation tool that can be quickly and easily applied in early stages of the design process without the need to involve real drivers.
