摘　　要：学习导航系统的目的在于避免学习者在学习过程中"迷失"方向和提高学习效率,并能在一定程度上消除"孤独"感,其关键是系统能够提供高效的导航机制,指导学习者完成学习任务。本文基于Petri网建模工具,利用知识结构理论和知识点关系对导航系统建模方法进行了探讨,并着重强调学习者的个性化学习,结合利用相关鱼眼图和感知处理技术建立了一套个性化学习导航系统。The key point of learning navigation system lies in its high efficiency to direct learners to achieve their study tasks in order to avoid losing in the study, improving learning efficiency and reducing the feeling of loneliness to some extent. This article discussed modeling method for navigation system with Petri Net based on knowledge structure and relation between knowledge nodes, and what＇s more, made the model of personalized Learning Navigation system paying much attention to personalized study of learner based on the technique of fish eye view and awareness processing.
