图形可视化的最终结果是人们阅读图形，理解数据。要使其有效，必须基于人们阅读图形的方式来构建可视化。尽管图形的使用在各种应用领域中很流行，也很重要，但人们对图形的阅读方式知之甚少。这种知识的缺乏严重限制了图形可视化的有效性。在试图了解人们是如何阅读图表的过程中，我们之前观察到，基于主观的眼球跟踪数据，人们具有测地线路径倾向。本文介绍了两个对照实验。一是肯定测地线路径倾向的存在。另一项是研究这一趋势对人们阅读图表的影响。结果表明，在执行路径搜索任务时，当眼睛遇到一个具有多个链接的节点时，更有可能首先搜索到指向目标节点的链接。实验结果还表明，在远离目标节点的路径上使用分支链接绘制图形时，可以显著提高图形读取性能。
The end result of graph visualization is that people read the graph and understand the data. To make this effective, it is essential to construct visualizations based on how people read graphs. Despite the popularity and importance of graph usage in a variety of application domains, little is known about how people read graphs. The lack of this knowledge has severely limited the effectiveness of graph visualizations. In attempts to understand how people read graphs, we previously observed that people have geodesic-path tendency based on subjective eye tracking data. This paper presents two controlled experiments. One is to approve the existence of the geodesic-path tendency. The other is to examine the effects of this tendency on people in reading graphs. The results show that in performing path search tasks, when eyes encounter a node that has more than one link, links that go toward the target node are more likely to be searched first. The results also indicate that when graphs are drawn with branch links on the path leading away from the target node, graph reading performance can be significantly improved.
