AI总结：
本研究通过用户实验探讨了VR拥挤行人环境中触觉反馈对用户行走行为的影响，发现触觉反馈能改变避障动作、增强侧后方感知与视觉探索，并提升对碰撞的敏感度。
摘要：
虚拟现实（VR）中的人群模拟是一种强大的工具，潜在应用包括紧急疏散训练和建筑布局评估。虽然VR中的触觉反馈能增强沉浸式体验，但其对密集且动态的行人流中行走行为的影响尚不明确。通过一项用户研究，我们调查了触觉反馈如何改变VR中拥挤行人流里的用户行走运动。结果表明，触觉反馈改变了用户的碰撞避让动作，具体表现为行走轨迹长度增加以及骨盆角度的变化。在与非玩家角色（NPC）发生碰撞的瞬时反应中，用户的横向位置和骨盆角度的位移也增加了，即使NPC处于视野范围内也是如此。当NPC从侧面和后方靠近时，触觉反馈还增强了用户的感知和视觉探索能力。此外，触觉反馈增加了行走速度的变化。这些结果表明，触觉反馈提高了用户对VR环境中碰撞的敏感度。
英文摘要：
Human crowd simulation in virtual reality (VR) is a powerful tool with potential applications including emergency evacuation training and assessment of building layout. While haptic feedback in VR enhances immersive experience, its effect on walking behavior in dense and dynamic pedestrian flows is unknown. Through a user study, we investigated how haptic feedback changes user walking motion in crowded pedestrian flows in VR. The results indicate that haptic feedback changed users' collision avoidance movements, as measured by increased walking trajectory length and change in pelvis angle. The displacements of users' lateral position and pelvis angle were also increased in the instantaneous response to a collision with a non-player character (NPC), even when the NPC was inside the field of view. Haptic feedback also enhanced users' awareness and visual exploration when an NPC approached from the side and back. Furthermore, variation in walking speed was increased by the haptic feedback. These results suggested that the haptic feedback enhanced users' sensitivity to a collision in VR environment.
