虚拟现实中的数字孪生在自动驾驶背景下的人车交互应用
Digital twin in virtual reality for human-vehicle interactions in the context of autonomous driving
AI总结：
本文通过虚拟现实和数字孪生技术测试自动驾驶车辆与行人的交互，发现虚拟HMI和平缓制动操作能促使行人更早横穿马路，且HMI激活能显著提升行人的安全感。
摘要：
本文展示了在虚拟场景中真实人类与模拟车辆之间交互的测试结果。通过面向行人的虚拟现实界面，将人类活动引入虚拟世界。自动驾驶车辆配备了虚拟人机界面（HMI），并驶过真实人行横道的数字孪生。当行人意图横穿马路时，HMI与平缓和激进的制动操作相结合。交互结果通过问卷以及可测量变量获得，例如行人启动横穿动作时与车辆的距离。问卷显示，只要HMI被激活，行人就会感到更安全，而改变制动操作对其危险感知的影响不大；同时，可测量变量表明，HMI激活和平缓制动操作均会使行人更早开始横穿。
英文摘要：
This paper presents the results of tests of interactions between real humans and simulated vehicles in a virtual scenario. Human activity is inserted into the virtual world via a virtual reality interface for pedestrians. The autonomous vehicle is equipped with a virtual Human-Machine interface (HMI) and drives through the digital twin of a real crosswalk. The HMI was combined with gentle and aggressive braking maneuvers when the pedestrian intended to cross. The results of the interactions were obtained through questionnaires and measurable variables such as the distance to the vehicle when the pedestrian initiated the crossing action. The questionnaires show that pedestrians feel safer whenever HMI is activated and that varying the braking maneuver does not influence their perception of danger as much, while the measurable variables show that both HMI activation and the gentle braking maneuver cause the pedestrian to cross earlier.
