Abstract. In this paper different interaction schemes which are currently implemented by major automotive manufacturers have been identified and analyzed. Complete overviews on all in-vehicle user-interface concepts are rarely spread. This paper gives a deeper insight in interaction schemes and userinterface concepts which are implemented in current cars. Additionally an expert review with 7 experts was performed to get a first impression which userinterface interaction schemes work well in the in-vehicle context. In order to get an impression of the suitability of the interaction schemes for the development of usable in-vehicle user-interfaces we performed different tests. The results are reported in text and tables.
