The Joy of Collaborating with Highly Automated Vehicles

Abstract

Fully autonomous driving leaves drivers with little opportunity to intervene in the driving decision. Giving drivers more control can enhance their driving experience. We develop two collaborative interface concepts to increase the user experience of drivers in autonomous vehicles. Our aim is to increase the joy of driving and to give drivers competence and autonomy even when driving autonomously. In a driving simulator study (N = 24) we investigate how vehicles and drivers can collaborate to decide on driving actions together. We compare autonomous driving (AD), the option to take back driving control (TBC) and two collaborative driving interface concepts by evaluating usability, user experience, workload, psychological needs, performance criteria and interview statements. The collaborative interfaces significantly increase autonomy and competence compared to AD. Joy is highly represented in the qualitative data during TBC and collaboration. Collaboration proves to be good for situations in which quick decisions are called for.
