In order to improve the efficiency of virtual software development and testing, we propose a VR visual programming toolkit based on gesture interaction. Considering that VR developers need to switch frequently between different operating environments during debugging, we suggest unifying the development and debugging of VR software in a virtual environment. Because of the low precision of keyboard input in VR, the applicability of text language in VR programming is poor. We propose a graphical language.

By modularizing common functions, developers can quickly edit program block diagrams through gestures and quickly test in plain clothes. On this basis, a visual programming toolkit under Unity environment is developed. Currently, the toolkit supports editing simple UI components and Shader in VR.
