本文介绍了两个相关的实证研究集中在不确定性可视化。实验框架从两个概念的角度。首先，不确定性的类型学是用来描绘各种不确定性匹配的空间，时间和属性的数据组件。其次，视觉符号学的概念被用来描述适合于代表这些不同类别的不确定性的视觉意义。这个框架指导了这里报告的两个实验。第一个地址表示直观性，同时考虑视觉变量和表象的象似性。第二个地址的相对性能最直观的抽象和图标表示的不确定性的地图阅读任务。综合结果表明，代表不确定性的初步准则和讨论的重点是结果的实际适用性。
This paper presents two linked empirical studies focused on uncertainty visualization. The experiments are framed from two conceptual perspectives. First, a typology of uncertainty is used to delineate kinds of uncertainty matched with space, time, and attribute components of data. Second, concepts from visual semiotics are applied to characterize the kind of visual signification that is appropriate for representing those different categories of uncertainty. This framework guided the two experiments reported here. The first addresses representation intuitiveness, considering both visual variables and iconicity of representation. The second addresses relative performance of the most intuitive abstract and iconic representations of uncertainty on a map reading task. Combined results suggest initial guidelines for representing uncertainty and discussion focuses on practical applicability of results.
