高度自动化车辆中听觉信息对视觉障碍者的影响
Effects of Auditory Information for People With Visual Impairments in Highly Automated Vehicles
AI总结：
该研究针对高度自动化车辆未兼顾视觉障碍用户无障碍性的问题，设计了视听沟通方案，通过在线视频研究对比三类听觉信息层级，发现补充信息可提升用户信任与体验，为自动化车辆无障碍设计提供了指导。
AI中文摘要：
自动化车辆有望提升所有人的无障碍性与个人出行可达性，但其设计及当前相关信息可视化研究趋势，未体现对视觉障碍用户的无障碍承诺。为此，我们为完全自动化车辆内的视觉障碍者设计并实现了视觉与听觉沟通方案。通过一项基于在线视频的研究（N=35，其中12人为视觉障碍者），我们对比了三个层级的听觉信息沟通：低层级（仅安全相关信息）、中层级（额外包含车辆控制与路线更新）、高层级（额外包含观光与目的地信息）。结果显示，补充信息可显著提升信任度与用户体验，对感知安全性的影响虽较弱但也存在；同时发现中层级信息已可能达到信息饱和。本研究通过引导设计者采用合适的信息沟通方式，助力提升自动化车辆的无障碍性。
英文摘要：
Automated vehicles promise to improve accessibility and access to personal mobility for everyone. However, their design and current research trends in visualizing relevant information do not reflect this commitment to accessibility for users with visual impairments. Therefore, we designed and implemented a visual and auditory communication concept for people with visual impairments seated inside fully automated vehicles. Furthermore, in an online video-based study (N=35, 12 with visual impairments), we compared three levels of auditory information communication: low (safety-relevant information only), medium (additionally including vehicle control and route updates), and high (additionally including sightseeing and destination information). Results showed that trust and user experience significantly improved with additional information, with a corresponding, albeit less robust, effect on perceived safety. However, they also revealed that a potential information saturation was reached with medium information. Our work helps to improve the accessibility of automated vehicles by guiding designers towards adequate information communication.
