外部人机界面（eHMIs）支持自动驾驶汽车（AVs）与行人等弱势道路使用者进行交互。虽然相关工作调查了各种eHMIs概念，但这些概念在单个时间点一次性传达其信息。当车辆接近行人时，与距离相关的多步信息是否能增加用户体验，目前还没有实证研究。我们进行了一项基于视频的研究（N = 24），其中eHMI概念为行人提供有关车辆意图的信息，而不提供任何进一步的上下文信息，并将其与两种新颖的eHMI概念进行了比较，后者在接近行人时提供额外的信息。结果表明，在eHMIs中增加基于距离的车辆信息，可以增强行人对车辆意图的理解，提高行人的过马路意愿。这一见解表明，距离依赖信息在eHMIs开发中的重要性，可以提高自动驾驶汽车的可用性、可接受性和安全性。
External human-machine interfaces (eHMIs) support automated vehicles (AVs) in interacting with vulnerable road users such as pedestrians. While related work investigated various eHMIs concepts, these concepts communicate their message in one go at a single point in time. There are no empirical insights yet whether distance-dependent multi-step information that provides additional context as the vehicle approaches a pedestrian can increase the user experience. We conducted a video-based study (N = 24) with an eHMI concept that offers pedestrians information about the vehicle’s intent without providing any further context information, and compared it with two novel eHMI concepts that provide additional information when approaching the pedestrian. Results show that additional distance-based information on eHMIs for yielding vehicles enhances pedestrians’ comprehension of the vehicle’s intention and increases their willingness to cross. This insight posits the importance of distance-dependent information in the development of eHMIs to enhance the usability, acceptance, and safety of AVs.
