摘　　要：可用性研究表明,虚拟现实应用除了展示三维场景,还要给出一个地图实现二维导航功能,这样才能使软件更加友好和易用。Turn Tool是一种功能强大的Web3D引擎工具,但由于其单通道特征,难以直接在其场景中实现二维导航的功能。提出一种用外部Flash对象作为导航图,依靠Java Script进行对象间通信的方法。依靠该方法,可以实现Web3D虚拟场景的二维导航。该方法有通用性,也可适用于其他Web3D引擎。Usability studies show that,in addition to displaying the three-dimensional scene,the virtual reality application need to provide a map to implement the two-dimensional navigation function,in order to make the software more friendly and easy to use. TurnTool is a powerful Web3D engine tool,but because of its single-lane feature,it is difficult to implement 2D navigation directly in its scene. This paper presented a method of using external Flash object as a navigation map and relying on JavaScript for communication between objects. By means of this method, twodimensional navigation of Web3D virtual scene could be realized. This method had versatility,but also could be applied to other Web3D engine.
