基于用户空间认知的网络信息可视化研究

Research of Network Information Visualization Based on Users' Spatial Cognition

"迷航"和"认知过载"是网络用户在浏览信息时经常遇到的问题,尤其是在网页链路较深的情况下,这种现象变得更为明显,而网络信息的可视化可以有效的解决这个问题。文章从空间认知理论的角度出发,结合认知心理学的研究成果,分析了用户的空间认知特征对信息可视化模型设计的支持作用。在此基础上,从模型框架的设计和模型的概念设计两方面详细探讨了信息可视化模型的构建。最后结合实例,验证模型的有效性与不足性。

There is a common phenomenon of disorientation and cognitive overload problem when users surf the Internet.Especially in the cases of deep link path,this kind of phenomenon becomes more apparent.Yet information visualization can effectively solve this problem.This article,from the angle of spatial cognition theory and combining with the research achievement of cognitive psychology,analyzes the users＇ space cognitive processes and characteristics,also how they support the design of information visualization model.Based on this,the paper discusses the construction of information visualization model from two aspects,which are model framework design and model concept design.At last,using an example,this paper demonstrates the validity and deficiency of the model.
