User experience (UX) in autonomous vehicles has been a growing area of research in recent years. Car manufacturers have presented various automated vehicles recently, ranging from combined ADAS to self-driving vehicles with the ability to drive without any human intervention. This workshop is the third in the series that started in 2013. The workshop brings together researchers and practitioners from various domains. This year the objective is to identify challenges that need to be addressed in order for the technology to become acceptable to society. We plan to develop a ten-point plan of research goals the automotive UI community must solve in order to improve UX in Autonomous Driving (AD). This includes a discussion on how we can face upcoming challenges in designing UX for AD, as well as, how to shape the design space for UX in AD. The workshop will focus on the areas of methodological issues, human factors, entertainment, social driving, and novel user interface approaches.
