本文介绍了StepTree，一个信息可视化工具，旨在描绘层次结构，如目录结构。StepTree类似于层次可视化工具Treemap，因为它使用矩形空间填充方法，但与Treemap不同的是，它使用三维空间，用于更清楚地传达层次结构的结构关系。本文包括一个实证研究，比较典型的搜索和分析任务，使用StepTree和Treemap。研究表明，使用StepTree时，用户在与解释结构关系相关的任务上表现得更好。此外，用户在执行一系列其他常见的解释和导航任务时，使用StepTree和Treemap实现了相同的性能。
This paper presents StepTree, an information visualization tool designed for depicting hierarchies, such as directory structures. StepTree is similar to the hierarchy-visualization tool, Treemap, in that it uses a rectangular, space-filling methodology, but differs from Treemap in that it employs three-dimensional space, which is used to more clearly convey the structural relationships of the hierarchy. The paper includes an empirical study comparing typical search and analysis tasks using StepTree and Treemap. The study shows that users perform significantly better on tasks related to interpreting structural relationships when using StepTree. In addition, users achieved the same performance with StepTree and Treemap when doing a range of other common interpretative and navigational tasks.
