Multimedia System Research And Implementation Of Experiment Based On VR Technology

VR technology is an emerging technology accompanied by the development of computer science, which uses virtual reality hardware and software resource to achieve a more complex communication and interactive process between people and computers. Arising from the use of VR technology, participants with a virtual space can be visual,heard,touched and other immersive experience, so that the participants can perceive and interact with objects in the three-dimensional virtual reality environment . VR techniques for the experimental teaching, give students a space of virtual experiment to strengthen their operational skills, to improve the existing status of experimental teaching, and improve effectiveness of experimental teaching.In this paper, based on a detailed analysis of VR technology, which discussed the VR technology using in the theoretical basis for experimental teaching, and carried out a detailed analysis for the development and design of virtual experiments using systematic instruction. In the works, VRML and 3DS MAX has been selected from the virtual reality technology to made the virtual scene modeling experiment, combined with JavaScript language, which explored the interactive features of the experiment and its implementation. The paper researched the organic integration between VR technology and experimental teaching, promoted the launching of experimental teaching , enhanced the application of the skills of students. Based on the analysis of multimedia systems in the classroom's teaching experiment, the paper designed and built a virtual experiment platform to support students in experiential learning, made a detailed analysis and design for the features of the video Showcase and the projector of the multimedia system, described the general process of making virtual experiment. At the same time the specific combination of the main technical issues in the multi-media virtual experiment operation (such as: virtual field throughout the building, the realization of the video booth button ,the expression of interactive features in virtual experiment, the embodiment of projector-related functions, etc.)had made a in-depth exploration and discussion.The virtual experiment system had run a trial upon completion of the development in the network environment, and the survey analysis confirmed the interactivity and immersion of virtual experiments will help improve the learners' interest in learning and enhance students' practical skills.
