In a co-operation between INARTE (TR 4014) and TELSCAN (TR1108) European projects additional usability tests of the IN-ARTE system were performed with a group of 10 elderly drivers. The subjects had to fulfil several interaction tasks with a virtual prototype of the IN-ARTE HMI. The system functions and the HMI were introduced to the subjects in a defined sequence. The user behaviour was observed and interviews were performed targeting at the evaluation of acceptance and usability of the IN-ARTE functions and HMI. Comparisons could be made with a group of younger drivers, who were involved in former IN-ARTE experiment with the same design. During the tests the experimentators found qualitative differences in behaviour between elderly (required more explanation, longer habituation phase) and other drivers. However the evaluation of the results concerning usability and acceptance of the IN-ARTE system did not show significant differences between the two groups. The expressed needs concerning the HMI were not different. Based oh these tests it cannot be concluded that the IN-ARTE concept and HMI requires special adaptations to the need of elderly drivers, but could be concluded that adapting the IN-ARTE interface to match the extended behavioural needs of elderly drivers results in a better interface for all.
