Formal semantics of higher-level information of graphical representations that informs the study of diagrams comprehension

众所周知，图同时表达的信息具有不同的专一性和抽象性。我们检查了阅读图表的人的眼球运动，以确定是否在理解图表时使用了高度抽象的信息（称为“高级信息”）。我们发现它实际上是被使用的，并得到了一个假设，即人们有一种特定的方式来控制他们对图表元素的注意力，而使这种控制更容易是图表表示的主要功能，而不是基于文本的信息。

It is known that diagrams simultaneously express information with different specificity and abstractness. We examined eye movements of people who read diagrams in order to determine whether high-abstraction information (called "higher-level information") was actually used in diagram comprehension. We found that it was actually used, and obtained the hypothesis that there is a specific way people control their attention to diagram elements and making such a control easier is a main function of diagrammatic representations as opposed to text-baed information.
