| 中文摘要: |
| 为了研究利用虚拟现实开展行人疏散实验的有效性以及虚拟场景里不同控制方式的优劣,开展了真实世界与三种不同控制方式(头显-鼠标(HM)、鼠标-鼠标(MM)、键盘-鼠标(KM))下虚拟场景的绕障实验。分析并比较了平均轨迹、绕障距离、绕障起始时间以及归一化时间下的横向距离。实验结果表明,当横向坐标小于1 m时,虚拟场景与真实世界实验平均轨迹的差值在10 cm之内。平均轨迹、绕障距离、绕障起始时间方面,HM更接近真实世界实验;归一化时间下的横向距离方面,MM更接近真实世界实验。 |
| 英文摘要: |
| In order to investigate the effectiveness of using virtual reality (VR) for pedestrian evacuation experiments and the advantages/disadvantages of different control methods in virtual scene, obstacle avoidance experiments were carried out both in real world and virtual reality, where participants navigated themselves by three different control methods (headset-mouse (HM), mouse-mouse (MM), keyboard-mouse (KM)). The average trajectory, avoidance distance, start time to avoid the obstacle and lateral distance under normalized time were analyzed and compared. The result shows that the difference of the average trajectories between real word and VR is less than 10cm when. In regard to the average trajectory, avoidance distance and the start time to avoid the obstacle, HM is closer to the real-world experiment, while MM is closer to the real-world experiment in terms of lateral distance under normalized time. |
