项目摘要

As the first step of developing the virtual reality simulator for safe space design, the VR application system for human behavior in a maze is developed. By comparison of simulation using the VR system and experiments using an real maze, the accuracy of reappearance of human behavior by VR system is proven and the effects of VR training on evacuation behavior is analyzed. The followings are the steps accomplished during these two years.(1)Development of VR application system for evacuation behavior : We developed a VR application software for human behavior in a maze. In the system, virtual reality space is simulated by using computer graphics.(2)VR experiment of human behavior in maze : The VR application system is modified by solving problems encountered by the study in the first year, such as lighting in a maze, opening and closing doors, realistic perceptibility of wall, floor, ceiling, etc.(3)Comparison of VR and real experiments using maze : We checked the agreement of behavior observed from both real experiment and VR simulation, and the effects of VR training. Evacuation experiments are carried out with three different groups, namely, a) experiment using only a real maze, b) VR training and experiment using real maze, and c) experiment using real maze after seeing the section of the maze. We studied the accuracy and effects of VR experiences by comparing the results from experiment using real maze and VR simulation.(4)Discussion towards advanced VR simulation system for safe space design : We discussed the results from the real experiment and VR simulation and pointed out the problems which should be solved to improve the system.

作为开发安全空间设计虚拟现实模拟器的第一步，开发了迷宫中人类行为的虚拟现实应用系统。通过与真实的迷宫实验的对比，验证了虚拟现实系统再现人的行为的准确性，并分析了虚拟现实训练对疏散行为的影响。以下是在这两年中完成的步骤。（1）疏散行为虚拟现实应用系统的开发：我们开发了一个迷宫中人类行为的虚拟现实应用软件。该系统利用计算机图形学模拟虚拟现实空间。(2)VR迷宫中的人类行为实验：通过解决第一年研究中遇到的问题，如迷宫中的照明，开关门，墙壁，地板，天花板的真实感知等，对VR应用系统进行修改。（3）虚拟现实与真实的迷宫实验的比较：我们检查了从真实的实验和虚拟现实模拟中观察到的行为的一致性，以及虚拟现实训练的效果。用三个不同的组进行疏散实验，即，a）仅使用真实的迷宫的实验，B）使用真实的迷宫的VR训练和实验，以及c）在看到迷宫的部分之后使用真实的迷宫的实验。通过比较真实的迷宫实验和虚拟现实模拟实验的结果，研究了虚拟现实体验的准确性和效果。（4）对先进的安全空间设计虚拟现实仿真系统的探讨：讨论了真实的实验和虚拟现实仿真的结果，指出了系统进一步完善需要解决的问题。
