Real-Time 3DUI Research Based on Virtools

The progress of virtual reality technology demands more about the real-time and naturalness of the interface. Based on the classification research on human-computer interfaces in 3D scene, this paper explored the real-time 3Dimensional User Interface (3DUI) in virtual reality interaction, and through practices on the 3DVIA Virtools platforms, presented the implementation principle and some specific operations of the interface.
