Abstract

In this research, we discuss five design parameters found in cognitive studies related to animated choropleth maps and compare existing studies accordingly. With reference to these parameters, we present the design of an experiment to assess how different forms of value generalization in choropleth map animation affect the perception of overall trends and local deviations therefrom. The mixed study design of the experiment allowed a direct comparison of within-subject and between-subject designs. Using repeated subsampling of our empirical data, the greater statistical power of the within-subject design was proven, even when correcting for differences in the number of data elements analysed.
动画地形图中价值概化模式的实验设计
在本研究中,我们讨论了与动画地形图相关的认知研究中发现的五个设计参数,并相应地比较了现有的研究。参考这些参数,我们提出了一个实验设计,以评估不同形式的价值概化在地形图动画如何影响整体趋势和局部偏差的感知。实验的混合研究设计允许直接比较受试者内部和受试者之间的设计。使用我们的经验数据的重复子抽样,更大的统计能力的主题内设计被证明,即使在修正数据元素的数量分析的差异。
