This paper reports the results of an inter-disciplinary study investigating user preferences and performance in relation to spoken in-car route guidance. In-car navigation systems are becoming increasingly popular. However, despite large amounts of research assessing the presentation of spatial information, and the usability and interaction issues surrounding the interfaces, there has been much less investigation of the impacts of auditory presentation of route information. We addressed this issue using a multi-disciplinary approach to collect both qualitative and quantitative data through questionnaires and user experiments. Our research identified a user preference for auditory presentation of route information, as well as a memory advantage for auditory over visual presentation. We also found that simple auditory route instructions could be followed without significant interference to a simulated driving task, whereas more complex auditory instructions did cause interference. Taken together, this research highlights the importance of the design of spoken route guidance instructions in minimising the cognitive demands that they impose.
