To enrich the "1+X" virtual reality skill level certificate training methods, this paper uses Unity3d game engine, GearVR

helmet and Galaxy S7 mobile phone to develop an interactive application of "1+X" virtual reality application development vocational skill level certificate (intermediate) based on oculus utilities and GearVR SDK. The virtual interaction is finally realized by focusing with helmet collimator, responding to input with gaze, click, ray, helmet touchpad and wireless controller, and cooperating with the animation state machine and UGUI system of Unity3d. It is packed into APK files and is tested on the galaxy S7 mobile phone platform. The test results show that the platform realizes the related functions. The research provides a virtual reality solution for "1+X" training.
