However, their potential has not been fully investigated to make use in international standards. To contribute to making authentic standards, the present paper investigated the effects of various non-speech displays to further refine auditory variables. Twenty-four young drivers drove in the driving simulator that had both handover and takeover transitions between manual and automated modes with a secondary task. The reaction times for handover and takeover and other sound user experience questionnaire results are reported with discussions and future work.6 page(s)application/pdfenIn CopyrightAuditory displaysmultimodal displaysautonomous vehiclestake-over requestConference proceedinghttps://doi.org/10.1145/3290607.3313078Jeon, Myounghoon [0000-0003-2908-671X]
