Virtual Reality Technology In Distance Education System In Applied Research

Virtual Reality is a technology which allows a user to interact with a computer-simulated environment, to experience feel and operate objects in virtual world in a native way, by using vision helmit, dataglove and other sensor feedback devices or using input devices like keypads and mouse etc. This technology utilize 3D Graphic technology, Multi-sensor interact technology and High-resolution display technology to generate a vivid 3D virtual environment. Immersion, interaction and imagination is three key characters of VR technology.Now, it's very difficult to use vision helmit, dataglove and other feedback sensor equipments widly due to technology and money reasons. But as computer science technology developing rapidly, Web3D technology is becoming more stable and consummate.Web3D use typical input devices like keypad, mouse, monitor to create an interactive environment in web browser in client machine. It is more and more widly used in internet.Web3D create a virtual space to realize human-computer interaction walkthrough, search and manage data by database interface, browse and interact 3D environment by browser and client end. Web3D upgrated current web technology and it is the core technology of next generation web technology.It can be widly used in digital city construction, company presentation,production marketing,remote education,travel promotion,exposition, military simulation etc areas.Moderm remote education enter a brand new phase, a lot of teaching media come to true.such as the mobile communication technology based remote mobile education, education based remote self teaching education,multimedia conference system based synchronous remote education, web game based experienced remote education,virtual community based asynchronous remote education, etc. So how to applicate VR technolgy into modern remote education system is getting more and more attention.This article analysed and designed "Electric Locomotive Distance VR Laboratory"which is based on VR technology by tracing VR researching steps and understand the status and development of modern VR technology's application. Try to use VR's core technology, especially the Web3D interative technology and virtual equipment technology. And discuss the design and realization of remote virtual lab education model.This article refers the following technolgy: dynamic web construction, virtual 3D environment construction, web 3D interaction, virtual equipment and modern remote education technology.
