104. Assessing Meaningful Visual and Tactile Feedback for Effective Automated Vehicle Takeover by Hearing and Non-Hearing Drivers
SessionPoster Session 2
DescriptionWith SAE Level 3 automated vehicles handling most driving tasks, there are still situations when the driver needs to take over. Multimodal displays have been introduced to inform drivers of the need to take over for critical scenarios (e.g., in construction zones) in instructional or informational formats. However, the effects of multimodal displays on takeover performance for drivers with hearing impairments are still unclear. Therefore, the goal of this study was to investigate how signal type (single-modal vs. multimodal), informational type (instructional vs. informational), and hearing impairment (hearing-impaired and non-hearing-impaired drivers) affect drivers’ takeover performance. Findings show signal type significantly influenced takeover and response times, with multimodal signals having faster reactions. Additionally, the instructional information type had a marginally longer takeover time than informational type. Hearing, however, did not affect takeover and response times. Findings may inform the development of future vehicles to assist drivers with hearing impairments.
