Abstract

Space-filling visualizations, such as the TreeMap, are well suited for displaying the properties of nodes in hierarchies. To browse the contents of the hierarchy, the primary mode of interaction is by drilling down through many successive layers. In this paper we introduce a distortion algorithm based on fisheye and continuous zooming techniques for browsing data in the TreeMap representation. The motivation behind the distortion approach is for assisting users to rapidly browse information displayed in the TreeMap without opening successive layers of the hierarchy. Two experiments were conducted to evaluate the new approach. In the first experiment (N=20) the distortion approach is compared to the drill down method. Results show that subjects are quicker and more accurate in locating targets of interest using the distortion method. The second experiment (N=12) evaluates the effectiveness of the two approaches in a task requiring context, we define as the context browsing task. The results show that subjects are quicker and more accurate in locating targets with the distortion technique in the context browsing task.

分级空间填充可视化的内容浏览技术评价

空间填充可视化，如TreeMap，非常适合显示层次结构中节点的属性。要浏览层次结构的内容，主要的交互模式是通过向下钻取许多连续的层。本文介绍了一种基于鱼眼的失真算法和连续缩放技术，用于在树状地图表示中浏览数据。扭曲方法背后的动机是帮助用户快速浏览显示在TreeMap中的信息，而无需打开层次结构的连续层。进行了两个实验来评估新方法。在第一个实验中(N=20)，将失真方法与钻入方法进行比较。实验结果表明，实验对象在定位感兴趣目标时能够更快、更准确地定位目标。第二个实验(N=12)评估了两种方法在需要上下文的任务中的有效性，我们将其定义为上下文浏览任务。结果表明，在情境浏览任务中，使用扭曲技术的被试能够更快、更准确地定位目标。
