Current Challenges in Compositing Heterogeneous User Interfaces for Automotive Purposes

Composition (i.e. merging distinct parts to form a new whole) of user interfaces from different providers or devices is popular in many areas. Current trends in the automotive area show, that there is a high interest in compositing interfaces from mobile devices into automotive user interfaces. “Apple CarPlay” and “Android Auto” are concrete examples of such compositions. However composition is addressed with challenges, especially if the parts are originally designed for different purposes. This paper presents the problem statement of compositing heterogeneous devices. Furthermore, it presents a layer model showing architectural levels, where compositions can take place and for each of these layers challenges have been identified.
