Abstract
Connecting personal devices to the in-vehicle infotainment system has become mainstream in modern vehicles, contouring a distinctive context of use characterized by the user interface being distributed across multiple interactive systems, including those in the vehicle and the users’ personal digital devices, likely involving different input and output modalities. However, distributed user interfaces (DUIs), despite extensively studied in other application domains, have not been addressed to the same extent for in-vehicle interactions. In this context, we examine in-vehicle DUIs and report the results of an exploratory study conducted with twenty-four drivers, who shared their preferences regarding digital device use inside the vehicle. To complement our findings, we also present a demonstrative application featuring a user interface with interaction modalities distributed across the in-vehicle infotainment system and the driver’s smartwatch.
