Abstract
AbstractThis builds on previous work in which we have developed diagramming principles based on theories of structural object perception. We call these geon diagrams. We have previously shown that such diagrams are easy to remember and to analyze. To evaluate our hypothesis that geon diagrams should also be easy to understand we carried out an empirical study to evaluate the learnability of geon diagram semantics in comparison with the well-established UML convention. The results support our theory of learnability. Both ”novices” and ”experts” found the geon diagram syntax easier to apply in a diagram-to-textual description matching task than the equivalent UML syntax.
