摘要
当前可视化分析软件对于人机交互的支持不足,造成分析推理过程效率较低。针对此问题,设计并实现了一个笔式可视化分析系统。首先分析了可视化分析过程的交互任务,然后提出了笔式可视化分析系统的体系结构,研究了基于草图的自适应布局算法,并对分析过程中的交互方式进行设计。最后给出了该系统的应用实例,可用性实验评估结果表明,该系统可以为可视化分析提供一种自然、高效的支持工具。
The shortage of the abilities which current visual analysis software support to human computer interaction has caused the lower efficiency of analytical reasoning.This paper designs and develops the pen-based visual analysis system from the point of the problem.Firstly the paper studies the visual analysis process.And then,puts forward the architecture of pen-based visual analysis system,discusses sketch-based self-adaptive layout algorithm and designs the way of interaction in visual analysis.Finally,it gives the application instance of the system and the experiment evaluation of usability.The result of the evaluation experiment demonstrates that the system can provide a nature and efficient supporting tool for visual analysis.
