Design and Evaluation of a Touch-Based Personalizable In-Vehicle User Interface

There is a trend of personalizable products at the same time as there is a substantial growth of functions in the automobile user interface. A research through design approach was used to explore the potential of a personalizable vehicle user interface to improve traffic safety as well as user experience by offering a product that is tailored to the user's own needs and preferences. A prototype was evaluated by 20 participants with several methods: interviews, Computer System Usability Questionnaire, Microsoft product reaction cards, and driving simulator measures. The prototype was experienced positively (flexible, easy to use, and usable), few usability issues were found, no negative effects on driving performance were found, and it was assumed that it could improve traffic safety. All participants stated that they would want to use such a system in their own cars.
