Vehicle automation is becoming more widespread. As automation increases, new opportunities and challenges have emerged. Given that vision is heavily taxed in driving, much research has been conducted on an auditory channel. To identify new design spaces and solutions, we have organized successive workshops and tutorial at International Conference on Auditory Display (ICAD) and AutoUI Conference for several years. In this report, we address novel opportunities and directions of auditory interactions in automated vehicles that we have discussed in the workshop and tutorial to design better driver user experience and secure road safety.
