基于Steam VR的交互仿真水枪灭火训练系统设计

为节约消防训练资源，增加虚拟现实训练的沉浸感和体验感，设计了基于Steam VR的交互仿真水枪灭火训练系统。采用霍尔传感器、信号转换电路板等硬件采集传输仿真水枪的开关信号，利用Unity3D引擎结合VIVE头戴显示器搭建、呈现虚拟现实火灾场景，通过C#编程控制水枪与虚拟火灾场景进行交互，完成系统的设计。结果表明：仿真水枪替代VIVE手柄控制器进行交互训练，能极大地提高受训者的沉浸感和体验感，提升受训者使用消防多功能水枪进行灭火的能力。

Design of Interactive Simulated Water Gun Fire Fighting Training System Based on Steam VR

In order to save the fire fighting training resources and increase the immersion and experience of VR training, an interactive simulated water gun fire fighting training system based on Steam VR is designed. By using the Hall sensors and signal conversion circuit boards to collect and transmit the signal of the simulated water gun, and by using the Unity3D engine combined with the VIVE head-mounted display to build and present VR fire scene. The gun is controlled through C# programming to complete the interaction with the virtual fire scene. The system is evaluated by a post-questionnaire survey and the result shows that for the interactive training, the trainees' sense of immersion and experience can be greatly improved by the simulated water gun instead of the VIVE handle controller.
