摘要
为解决目前网络虚拟环境下信息交互因缺乏导航理论而产生的各种现实问题,如用户容易产生疲劳感与"迷航"现象,引入智能导航的设计思想。对组成智能导航系统的3个关键技术(信息推荐、路径规划与数据预取)进行了深入地分析与研究;提出了适合网络三维虚拟环境关键技术的相应改进算法;接着整合3种技术,设计了带智能导航功能的三维网站原型系统;最后通过构建网上三维虚拟博物馆,表明智能导航系统的工作性能。
To solve the problems,such as easily making visitors feel tired and disorientation,which stem from lack of navigation theory during information interaction under networked virtual environment（NVE）,the theory of intelligent navigation system（INS） is imported into NVE.Firstly,three key technologies,information recommendation,path planning and data prefetch,are deeply analyzed and researched.Secondly,the algorithms about those key technologies are improved to be fit for NVE.Thirdly,above technologies are integrated together efficiently;and then the 3D-web prototype system with intelligent navigation is designed.Finally,through constructing 3D virtual museum based on web,the good performances of intelligent navigation are verified.
