Conception, Development and First Evaluation of a Context-Adaptive User Interface for Commercial Vehicles

Modern vehicles are complex working environments and feature a multitude of functionalities. This applies in particular to commercial vehicles, which are equipped with even more functions than passenger cars. Research showed the potential of context-adaptive user interfaces for reducing the complexity of the human-machine interaction but has focused on passenger cars. Therefore, a context-adaptive touchscreen-based system is conceptualized specifically for commercial vehicles such as trucks based on existing findings and design guidelines. Acknowledging the importance of being able to gather early user feedback for allowing fast iteration cycles, an interactive prototype was implemented, and a modular study setup developed. This combination was tested in an initial user study, which evaluated the usability as well as user experience in terms of the novel context-adaptive interface.
