Among the phases of self-driving, the transition of control over driving from vehicles to drivers occurs in the conditional self-driving phase. Therefore, designing appropriate user interfaces to perform safe control transitions is crucial. However, most previous studies have focused on evaluating the performance and safety of self-driving systems. In the conditional self-driving phase, no regulations that can force drivers to control their eyes currently exist, meaning the control transition, which relies solely on the visual-centric user interfaces used in traditional driving environments, is not safe. Therefore, in this study, we developed guidelines for an auditory user interface design to ensure safe control transition. We derived these guidelines by applying a user experience design methodology and defining important principles in the appropriate combination of voice and sound feedback.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citationsโcitations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
