We are pleased to present to you the Adjunct Proceedings of the 11 th ACM International Conference on Automotive User Interfaces and Interactive Vehicular Applications (AutomotiveUI '19), hosted by Utrecht University in the Netherlands. AutomotiveUI is the premier forum for user interface (UI) research in the automotive domain, bringing together researchers from both academia and industry. As in previous years, the papers and presentations of AutomotiveUI '19 target the development of novel vehicle technologies based on principled models and concepts that seek to enhance driver experience, safety, and performance; the development of semi and fully autonomous driving; and the needs of different user groups, including passengers and pedestrians. This year's topics covered a variety of themes. Specifically, the sessions focused on designing spaces and interfaces, Auto-UI today, driving assistance systems, automated driving, driver displays, multimodal interfaces, multimodal interaction, and visual-manual interaction. The papers are representative of the diverse disciplines and research methodologies that make key contributions to AutomotiveUI research, with submissions from both academia and industry. This year, we requested authors to specify the area of their research contribution, namely design and user experience, software and technology, user studies and human factors, research methods and simulation. We were pleased to have received submissions in all categories, which were suitably reviewed by experts in these areas. In particular, this year's submissions bears witness to a growth in the diversity of topics and institutes, relative to previous years. This highlights that our community is still growing and that AutomotiveUI research continues to be relevant across the world. Submission and Review Process The main papers track, which are reported in the main proceedings, feature papers of 6-10 pages. In total, we received 119 submissions: a record number for AutomotiveUI, with near 25% increase from previous year. The intensive review process was led by the technical program chairs, who were aided by 51 Associate Chairs, and 141 reviewers. Finally, we would like to thank our sponsors and exhibitors in supporting the conference. Sponsorship and exhibitors bring incomparable visibility to the leading conference on Automotive User Interfaces and we are grateful to have an exciting number of renowned international institutions and companies support us.
