Fig.5 EasyMonitor import VR monitoring SDK is built into VR application once above steps are all done, and the application may distribute to users after re-compelling. Real-time data collection and upload including user device, operation performance, crash report and user interaction can be realized upon operation in user environment. Data analysis platform receives data from SDK, carry out statistics analysis, and finally generate report for developers. In this study, the VR application is operated in a user environment which is exactly the minimum requirement from the application. 5.2 Results Real-time monitoring is realized, and reports including use of handle object, 7-day usage, runtime frame rate, crash information are generated, shown as Fig. 6 -- 11.
