ABSTRACT

Dynamic maps are commonly used for the depiction of quantitative information. However, their users often fail to notice changes in the intensity of geographic phenomena. Moreover, if the distribution of colour values between two scenes changes, the user might have a problem with recalling the colour arrangement from the previous scene. A commonly occurring mistake is indicating that the colour changed its value, while in reality it did not. This paper examines the potential impact of the magnitude of change on the detection of the fixed enumeration units of a dynamic choropleth map. The research is based on Signal Detection Theory methodology and uses eye-tracking technology to examine the change blindness phenomenon on spatiotemporal maps. The results show that regardless of the magnitude of change and the number of enumeration units, the participants were convinced that the colour value in a particular place changed, even though it did not.

摘要

动态地图通常用于描述定量信息。然而，他们的用户往往没有注意到地理现象强度的变化。此外，如果两个场景之间的颜色值分布发生变化，用户可能难以回忆起前一个场景的颜色排列。一个常见的错误是表明颜色改变了它的值，而实际上它没有。本文研究了变化幅度对检测动态等值线图的固定计数单位的潜在影响。该研究基于信号检测理论方法，并使用眼动追踪技术来检查时空地图上的变化盲现象。结果表明，无论变化幅度大小和计数单位个数，
