In-car communication systems (ICCS) are becoming a common feature in today's cars, however they can cause distraction due to usability issues and competition for driver attention. Several multimodal interfaces have been designed and implemented using speech in order to allocate the driver's hands and eyes solely to the driving task. A lack of feedback and flexibility in some ICCS still contributes to increasing the cognitive load of the driver and negatively affecting the user experience. This paper discusses the design and evaluation of MIMI (Multimodal Interface for Mobile Info-communication), a multimodal prototype that was designed to address the usability issues with existing ICCS. Several communication tasks were evaluated using the following metrics: time on task, task completion, workload, flexibility, error prevention and feedback. Results obtained show high rates of perceived usability in terms of time on task and task completion rates due to the flexibility, feedback and error prevention provided by MIMI. The results show that multimodal input can contribute to preventing errors; however commands where speech input cannot be combined with manual input (e.g. dictating a phone number), are still negatively affected by speech recognition errors.
