Abstract
In the context of Self-Driving Car, vehicles would sometimes request for manual. Auditory display is one of the key Multi-Modal interaction channels widely applied in In-Vehicle interaction. Audio prompt consists of loudness, pitch, timbre and frequency which determine the auditory User feedback. In order to design user-friendly audio prompt, we involved UX design approaches to Auditory display design. This study introduced a new audio prompt design solution called Self-Autopilot Driving takeover audio prompt (SADTAP) which applied User-Centered Design (UCD) in the design process. We conducted a user interview with 9 typical users. UX factors has been decoded from the interview script. We designed a set of audio prompts basing on the UX factors and evaluated them by VR user experiment. 20 users have been invited to the lab and experienced virtual driving simulator. We have set up a virtual Self-Driving vehicle cockpit and highway virtual environment via VR Head Mounted Display (HMD) and used Wizard-of-Oz to stimuli the manual takeover situation while playing the audio prompt simultaneously. Users were requested to fill a SUS questionnaire after experiment. A data analysis results of the collected questionnaire were presented. The result showed positive outcome, proving our design solution - SADTAP - an effective improvement of the vehicle takeover request audio prompt.
