In this paper, we propose the use of the body gesture, instead of mouse and keyboard, as an interface to browse the exhibited multimedia video contents. For real applications, we have defined some control modes, which are based on human natural movements, to construct the commands of interactivities. These commands controlled a body gesture, are able to be built to control a virtual reality system for enhancing user's experiences of exhibitions. In our demo system, this body gesture offers a more nature and intuitive interface for the users, who easily walk through a virtual environment, which is created by specific oil paintings generated by graph engines. The proposed system can help the viewers to obtain more information about those paintings such that we can enhance their exploration experiences in touring multimedia contents.
