The XR-based firefighting facility inspection and operation simulation system is educational content on how to inspect and operate firefighting facilities. In an environment where training is difficult due to time and space constraints, you can learn how to use it correctly by inspecting and experiencing operation in a virtual environment through Microsoft Hololens2. This content is only available for training on the operating principles of powder fire extinguishers among the XR-based firefighting facility inspection operation simulation systems. We provide simple training on the operation of powder fire extinguishers. Tutorials help you learn basic gestures such as touch and swipe. * This content can only be run in the Microsoft Hololens2 environment. * This content is a trial version of only a portion of the XR-based firefighting facility inspection operation simulation system.
