Summary
This paper introduces InShift, a novel concept for a shifting in-vehicle infotainment system (IVIS) designed to enhance co-driver experience and facilitate driver-passenger collaboration. The research addresses the problem of driver distraction caused by non-driving-related activities (NDRAs), which significantly increase crash risk and mental workload. While current IVIS designs often restrict passenger interaction or rely on touchscreens that are difficult to use in shaky environments, InShift proposes a physical interaction model that allows drivers to delegate specific, mentally demanding tasks to the front-seat passenger. The primary goal is to reduce driver distraction while actively involving the passenger, thereby improving the overall in-car experience. The authors developed a physical prototype consisting of a motorized IVIS screen capable of moving between the center dashboard and a position directly in front of the passenger. This movement is controlled by an interactive panel featuring four buttons and a slider, integrated into the center console. The system operates in three modes: Non-Collaboration (driver retains full control, screen centered), Full-Collaboration (all functions delegated, screen moves to passenger), and Semi-Collaboration (specific functions delegated, screen remains centered but displays a split-screen interface). The buttons allow the driver to select which functions to delegate, while the slider confirms the delegation and adjusts the screen position. A pilot study was conducted with eight participants (four pairs from Dutch households) using a between-subject design. Participants performed four experimental tasks involving navigation, media control, and climate settings in a simulated driving environment. Results from the pilot study indicate that InShift offers a positive user experience for both drivers and co-drivers. Qualitative feedback revealed that the system effectively supports driver-passenger collaboration, allowing the co-driver to act as a better assistant by taking over specific tasks. The physical interaction elements, particularly the slider and buttons, were noted for providing clear spatial mapping of task delegation and preventing unauthorized access. The ability to personalize which functions are delegated helped drivers manage their mental workload by offloading highly demanding tasks while maintaining control over others. The significance of this work lies in its contribution to collaborative in-car system design. By demonstrating a tangible interaction concept that physically shifts the interface based on collaboration needs, the paper highlights a viable approach to reducing driver distraction without compromising safety. The findings suggest that fostering active passenger participation through dedicated, physical controls can enhance trip experience and driving safety. This concept offers a foundation for future IVIS designs that prioritize shared control and collaborative usage, moving beyond traditional driver-centric interfaces.
