Abstract


Virtual reality technology is an emerging technology involves many disciplines and fields of computer graphics , artificial intelligence and multimedia , has broad application prospects . Has become a hot topic in the educational applications of technology, by the majority of the attention of educators . How the effective use of virtual reality technology to education, improve the education service capabilities of virtual reality technology has become to explore one of the goals of the educators . In this paper , behaviorism , cognitive learning theory and constructivism as the representative of the basis , select the virtual reality technology in the VRML ( Virtual Reality Modeling Language ) and 3DS MAX for technical support, VRML and camera combined with experiment , build a virtual camera experiment teaching system, to explore this new experimental form of combination of virtual reality technology and traditional camera experimental teaching . Based on the combination of a specific TV program production course content , design and development of nine experimental content and the key technical issues in the experiment , such as : the realization of the camera model interactive features ( white balance, focus, exposure) , adjusting focus on the shooting realization , adjust the aperture , shutter control exposure and thus affect the realization of the shooting and the fixed lens , camera movement , composition and other exercises , the implementation of the camcorder playback and virtual campus scene roaming comprehensive experimental development conducted in-depth research and discussion . To enable students to master the basic operation of the camera in the simulation system , the completion of the the camera experiments required part of the experiment link . Finally , the entire system has a Web-based virtual experiment through trial confirmed situational , interactive, immersive , and so on , help to improve the learners ' interest in learning , learning efficiency ; make up for the lack of actual teaching , to facilitate the use of classroom teaching and distance learners advantages .
