Applicability Analysis on Three Interaction Paradigms in Immersive VR Environment

The work intends to research the characteristics and applicability of three different types of interaction paradigms in immersive VR environment. For this purpose, a three-dimensional VR scene is designed based on the Unity3D simulation engine, and three types of interaction paradigms, including graphical user interface interaction paradigm, gesture interaction paradigm and voice interaction paradigm, are developed into this VR scene respectively. And the designed immersive and interactive scenes are experienced with HTC Vive. Taking into consideration the development of three interaction paradigms, the computational costs of the running scene with different type of interaction paradigm, and the user learning cost, the characteristics of the three types of interaction paradigms areexploredandcomparedwitheachotherforapplicabilityanalysis. Furthermore, the recommendation for selecting the appropriate interaction paradigm in different circumstances is provided according to analysis result.
