Evaluation of speech-based HMI concepts for information exchange tasks: A driving simulator study ?
We compare different speech-based in-car HMI concepts in a driving simulator study. The HMI concepts are evaluated in terms of usability and driver distraction. The comparison of speech dialog strategies revealed only differences in usability. The use of a GUI impaired the driving performance and raised gaze-based distraction. An avatar does not additionally raise driver distraction but is not accepted by users.
