Development and Initial Evaluation of an Assisting Display Concept for Driving Wizards

To realize the full potential of automated vehicles (AVs), human-vehicle interaction needs to be modified to enable extended use cases, such as working or resting during the ride. The majority of required user studies are conducted in a driving simulator, but the usage of Wizard of Oz (WoOz) vehicles is becoming more common among researchers. To assure scientific quality of such studies, driving wizards must be able to successfully mimic the driving behavior of an AV. Yet, as far as we know, no detailed quantitative description of how driving wizards should drive and few techniques to assist driving wizards with their task exist in the literature. This work contributes to the standardization of WoOz studies by describing a potential AV-like driving behavior. Furthermore, using heuristic evaluation, three prototypical assisting display concepts for driving wizards are presented and assessed. Building on this, guidance toward an improved concept is provided.
