Interaction design for nomadic devices in highly automated vehicles

Following the roadmaps of (inter)national committees, highly automated driving will be available in the next decade in production vehicles. This technology allows the driver to do some other tasks while driving and to remain only as a fallback in situations the automation is not capable to handle. This study tested if nomadic devices, that drivers might use while driving highly automated, can be integrated to support the driver in taking over control when requested. 33 drivers participated in a simulator study and drove in a highly automated vehicle on a motorway. The results showed that the takeover performance of drivers improve if the takeover request is displayed additionally on the nomadic device. Therefore, the integration of additional interfaces such as smartphones into a holistic interaction concept may be a key aspect for designing a secure and comfortable takeover process.
