This paper studies the current application and monitoring situation of VR technology. Based on the Unity 3D game engine and VR device HTC Vive, the paper establishes a typical VR interaction scene and propose a VR application runtime monitoring scheme. The main work of this paper includes: (1) VR interactive scene where full-angle observation, movement of the person’s perspective, object touch, object picking, object use and menu interaction are achieved; (2) VR monitoring SDK. The monitoring SDK collects the user device information, runtime performance information, exception information, and user behavior information for the VR application under the user environment, by mounting a monitoring script in the VR application scene; (3) Data analysis center, which is responsible for receiving and storing the data reported by the VR monitoring SDK and helps helps the developer to better understand the situation on operation of the VR application and analyze user behavior through statistics aggregation and algorithm analysis of the data.
