Designing context-aware in-car information systems

ABSTRACT

In-car information systems are becoming increasingly complex. A multiplicity of functions in the area of navigation, information, communication, entertainment, comfort and security is available to the driver. The human-computer interaction is situated in a highly dynamic environment with specific demands to the drivers' cognition. The dynamically changing context can influence the quality of interaction, e.g. with regard to the usability. Systems with user interfaces that adapt to context information are potentially capable to offer a suitable quality of interaction by adressing the drivers needs and goals in varying driving situations. However, adaptions of the user interface also hold threats to the quality of interaction. In a qualitative user study this work explores the users' reaction towards a context-adaptive user interface of an in-car navigation systems regarding information display and interaction mechanism. The basic challenge discussed in this paper is the question whether and how context should be an influencing factor for the user interface and user interaction.
