提高虚拟火场临场感的研究

Research to improve the feeling of the virtual fire environment

针对传统消防科普教育培训中存在的问题,研究利用虚拟现实技术搭建火场虚拟环境,构建一个火场逃生虚拟体验系统,并以Unity3D为基础设计平台实现了提高虚拟火场临场感的设计。其临场感的建立主要依赖于来自虚拟现实系统反馈的场景信息,同时通过环境控制系统改变用户的听觉、触觉、温感、光感等外界刺激信号。将这些信号与虚拟场景相融合并给予用户反馈,就可以提高用户对虚拟火场的直观感受。

In view of the problems existing in the traditional training of fire science popularization education, to build virtual environ ment of fire using virtual reality technology was researched. The virtual reality simulation system for escape from fire was estab lished, and using Unity3D as basic design platform, the design of improving the feeling in fire was made. The establishment of feel ing mainly depends on the real-time feedback information of virtu al reality simulation system,meanwhile,through the environment control system, the user＇s sense of hearing, touch, temperature, light stimulation signal can be changed. The user＇s feelings for vir tual fire can be improved through matching these signals with the virtual scene and giving users feedback.
