| The price of the computer and accessories has fallen now than ever before as time goes by. During the past decade the price of Virtual Reality (VR) products has also been reduced steadily. In the past time the price of the VR products were too higher to use in education. Until now it can be used gradually in all kinds of education institutes. As described in the film "The Thirteenth Floor" (1999) and "Blade Runner" (1983), The future society will be a society mixed with work and entertainment. In the meanwhile, the education pattern and methodology will be reformed and popularly deployed correspondingly. As a new learning method with the use of VR related products, in one part, learners can get experiments and tastes from the reality world; In the other part, educators such as teachers can gradually teach students by means of pedagogical thinking of the new digital era .The idea of how to develop and utilize VR related products associated with the level of VR technology in existence is a dilemma which educators have to face now. First of all, this thesis begins with the background of VR, clarifies the VR in education, analyses the evolvement of the VR and circumstance of the VR in education, expounds how the VR technology--a new media delivering knowledge and a new cognitive tool--backs up the learners to construct their knowledge by themselves in psychology. Furthermore, the thesis expounds the VRML (Virtual Reality Markup Language) and X3D (Extensible 3D) standards and emphasis on the MPEG4 technology. At last, the thesis takes an example for designing a VSS application with the MPEG4 technology. Combined with the technology MPEG4,XML,X3D, the Virtual Reality technology originated from the Computer Graphics makes a great leap with the effect that is a good likeness of the reality. |
