A big trend in the automotive industry is the increasing interconnectedness of divergent systems both within and outside of the car. This results in an increased flow of information between the driver, the vehicle and the environment, which directs the focus away from the actual driving task. HMI has to be designed so that driver distraction is reduced to a minimum. There are some automotive HMI regulations, such as the NHTSA guidelines or DIN EN ISO 15005, which can be used to evaluate the usability and driver distraction of automotive interactive systems. On detailed analysis, however, the requirements of those guidelines and norms relate rather to already implemented systems or interactive graphical prototypes. At this very late stage, the elimination of identified HMI problems is very costly and time consuming.
A process model, which can determine the usability of comfort, entertainment, communication and infotainment tasks in early phases of automotive HMI development, is presented. It describes how the evaluation criteria are derived and how the expert-‐ based evaluation takes place. The evaluation process is defined so that experts as well as people without methodological knowledge can handle it.
Christoph Muehlbauer, has been working in the field of HMI since 2006 and has hands-on experience in UI Design, Programming and Usability Testing. He graduated with a master degree in Human Computer Interaction at the University of Siegen in 2012 and started his Ph.D. Program at the Technical University of Ilmenau.
Before joining the Porsche AG, he worked as a UX Specialist for different digital agencies within Europe. At Porsche AG he is a Project Manager who is responsible for all UX Activities associated to Connected Car and Automotive Mobile Apps. This includes, among other things, the design of new services, the definition of the Design Language as well as the evaluation of the product quality.
