How to support level-compliant driver behavior in automated driving with optimized User Experience?

Abstract

The research project KARLI is funded by the German Federal Ministry for Economic Affairs and Climate Action. Ensuring level-compliant driver behaviour in different SAE levels of automation is necessary for safe driving in automated vehicles. User Experience is considered relevant for user acceptance of those automated systems. In a qualitative study, 40 innovative ideas for interaction in automated driving were reflected in terms of User Experience. This was done by twelve individuals out of four different user groups – young people, frequent drivers with automation experience, people with children and people aged 65 and older. They evaluated the 40 ideas integrated in different concepts of automated driving, which were presented in user narratives. The evaluation was conducted across six UX facets (according to Engeln & Engeln, 2015): task (incl. interaction), self-expression, learnability, convenience of use, joy of use and aesthetics. The results provide important design insights for the development of interaction concepts for automated vehicles. Based on these findings, the interaction concepts to support level compliant driver behaviour were further elaborated and will be re-evaluated in an upcoming virtual reality experiment.
