Application Research Of Virtual Reality Technology In Laboratory Safety Education

With the development of computer level and new media technology,emerging computer technologies have emerged,and Virtual Reality(VR)has also emerged.lt is a computer simulation system that creates and experiences a virtual world,using a computer-generated simulation environment,and then immersing users in the environment for real-time experience.The technology is characterized by real-time and intuitive features and is widely used in many fields.This topic investigates and analyzes the application and research status of fire safety test bank,virtual fire extinguishing and virtual reality technology.Compared with the current mainstream external devices,the VR integrated machine HTC Vive was selected to apply virtual reality technology to the development of laboratory fire safety education system,and to learn the principles of virtual reality technology based on HTC Vive equipment.The preliminary work is mainly to investigate the common fire situation in the laboratory and collect the test bank mainly facing the hidden dangers of the laboratory,and then design the overall development ideas,find the implementation method,and explore the feasibility and difficulty.In the mid-production process,3ds Max,one of the mainstream 3D modeling software,and Substance Designer,a material design soffware,were used to build a 1 to 1 ratio virtual simulation lab scene and other sub-scenarios.After the model is built,it is imported into the Unity 3D engine.After the virtual reality environment is built,the model is restored according to the appearance of the real scene.The user interaction with the virtual environment is completed with HTC Vive and C#scripts,and the entire system is finally built.The system mainly includes two modules:the knowledge question bank module and the actual exercise module.The user can send the ray through the handle to switch between the start scene,the question bank scene and the drill scene.The user mainly feeds the virtual environment to the user’s eyes through the HTC’s head display,and then interacts through the handle touch or send rays to achieve other operations such as fire extinguishing,answering,advancing and retreating scenes.The advantage of this topic is not only the combination of HTC Vive for a novel immersive interactive experience,but also the ability to put users in a fire scene,especially in the experience of some dangerous fire scenarios,to avoid real fire-fighting operations based on real crisis.To deepen the fun and security of user learning.
