Speech, buttons or both? A comparative study of an in-car dialogue system

• In the DICO project a user test was performed to evaluate an in-vehicle dialogue system with three different modalities; speech user interface (SUI), graphical user interface (GUI) and multimodality (MM). Task performance, task comple- tion time and driving ability were measured. We found that although the GUI was fast and easy to use, the participants experienced that their driving ability was better when us- ing the SUI and multimodal interfaces, and the multimodal interface was preferred over GUI and SUI.
