摘要
针对当前网状信息可视化技术忽略了网状信息节点的可视信息的问题,提出一种面向网状信息的Radial+Focus可视化技术。首先介绍网状信息节点的信息详细度与先验重要度,并研究通过节点的交互历史计算节点的先验重要度的方法;然后研究了基于节点先验重要度的Radial+Focus布局算法;最后,给出了Radial+Focus可视化技术的应用实例和实验评估。实验评估表明,该技术能自然、高效地可视化网状信息,为用户对网状信息关系及网状信息节点的可视信息的分析提供有力的支持。
To solve the problem that existing network information techniques overlook the visual information of network information nodes,this paper put forward a Radial ＋ Focus visualization technique. Firstly,the paper introduced the degree of priority importance of network nodes,and then studied the function relation between the degree of priority importance and interaction history. Secondly,it studied the layout algorithm based on the degree of priority importance. Finally,it gave the application instance of Radial ＋ Focus technique and the evaluation experiment of usability. The result of the evaluation experiment demonstrates that the technique can display network information with visual nodes effectively,and provide powerful support for users’analysis to relations and visual information of network information nodes.
