The Tentative Research On The Application Of Virtual Reality In Physics Experiment

With the development of science and technology, the popular technologies are widely used in the educational field. Technology brings education a new life.Virtual Reality is becoming more and more popular at this time. The application of Virtual Reality is various because of its three main characters, which are interactivity, immersion and imagination. However, VR is used only in initial stage in the educational field nowadays. Therefore, more and more researchers focus on the application of VR in education these days.This thesis surveys the present situation of experimental instruction, and then points out the problems. For example, the condition of the lab is usually limited, and the lab is not open at any time so the students don't have enough opportunities to practice and so on. After analyzing VR and its related technologies, the thesis tries to build virtual experiment to solve these problems based on VR.In the former part of the thesis, some key words and main technologies are introduced. The first chapter illustrates the source of the thesis, the present situation home and aboard, and the thesis's significance. Chapter 2 concerned about some knowledge of VR, such as its concept, its history, its character, its application etc. Something about virtual experiment is also introduced. Chapter 3 discusses the basic theories which the thesis uses and analyzes the technologies related to VR, such as VRML and Java. This chapter is critical to the following part.Next, according to the theory and technology we analyzed just now, virtual experiment is designed in Chapter 4. It contains four main modules. And the experimental module is the most important module among them. There are two parts in this module. One is the text part, which produces something about the experiment, such the purpose, the steps, the principle of the experiment and the introduction of virtual instruments, the other is the virtual reality part. The two parts can be connected with the connection between VRML and Java. In addition, some key technologies are analyzed here. Chapter 5 is the key of the thesis. A virtual experiment about physics is developed in this chapter.The last chapter discusses the insufficiency of this virtual experiment developed in this thesis, and presents some programs for the further work.
