In this paper, we conduct analysis on the current condition of virtual reality and the computer graphics and the applications on the digital media interaction. We proposed the systematic review of the digital media interaction modes with the theoretical analysis of the virtual reality and computer graphics. Multimedia gateway is a separate control of the entire media interaction center core components, has the media docking and adaptation, multimedia intelligent routing, configuration and management, and other functions and at the center of the centralized control of all media interaction, the configuration and management of multimedia intelligent routing. With this basis, we integrate the 3D reconstruction methodology to propose the new perspective of the digital media interaction paradigm. The man-machine interface design principles should include the basic principles of general interface design, analysis and man-machine interface specification and the type of interface requirements. Our review summarizes the characteristics of the method well and in the future, the VR integration with the multimedia system and optimized re-construction method and image representation algorithms will be considered.
