论文摘要
可视化诸如条形图，散点图和地理图上的对象之类的可视化通常会使用形状传达关键信息，包括精确和相对数字值。编码信息的形状和方法的选择通常是任意的，或基于惯例。但是，过去的研究表明，人眼可以被视觉表现形式所欺骗。 Ebbinghaus的幻觉表明，感知到形状的相对大小取决于它们的配置，这反过来又会影响判断，尤其是在比例符号图等可视化中。在这项研究中，我们评估了改变形状和指标类型的效果，以在时空地图界面上编码视觉表示中的数据。我们发现，某些形状和度量的组合比其他制度更有利于准确的人类判断，并提供了将这些发现应用于以后的可视化设计中的建议。
Visualizations such as bar charts, scatter plots, and objects on geographical maps often convey critical information, including exact and relative numeric values, using shapes. The choice of shape and method of encoding information is often arbitrarily, or based on convention. However, past studies have shown that the human eye can be fooled by visual representations. The Ebbinghaus illusion demonstrates that the perceived relative sizes of shapes depends on their configuration, which in turn can affect judgements, especially in visualizations like proportional symbol maps. In this study we evaluate the effects of varying the type of shapes and metrics for encoding data in visual representations on a spatio-temporal map interface. We find that some combinations of shape and metric are more conducive to accurate human judgements than others, and provide recommendations for applying these findings in future visualization designs.
