Cartographic Redundancy in Reducing Change Blindness in Detecting Extreme Values in Spatio-Temporal Maps

Abstract

Abstract:The article investigates the possibility of using cartographic redundancy to reduce the change blindness effect on spatio-temporal maps. Unlike in the case of previous research, the authors take a look at various methods of cartographic presentation and modify the visual variables in order to see how those modifications affect the user's perception of changes on spatio-temporal maps. The study described in the following article was the first attempt at minimizing the change blindness phenomenon by manipulating graphical parameters of cartographic visualization and using various quantitative mapping methods. Research shows that cartographic redundancy is not enough to completely resolve the problem of change blindness; however, it might help reduce it.

Effectiveness of Memorizing an Animated Route—Comparing Satellite and Road Map Differences in the Eye-Tracking Study

“…They concluded that vividness/distinctiveness is a major factor of route memorization. This corresponds to Cybulski and Medyńska-Gulij's [39] findings that cartographic redundancy is influential in the change detection of animated stimuli.…”

“…Already, Wilkening and Fabrikant [69] noticed in their research that time pressure negatively affects map-based related tasks. The difficulty is an aspect of the animation that is crucial for effectiveness, as has been proven in many recent studies [8,25,39]. Moreover, this study proves that the number of turns of an animated route reduces the effectiveness of memorizing by several percent.…”

Empirical Insights from a Study on Outlier Preserving Value Generalization in Animated Choropleth Maps

“…Cartographers explored a number of ways to reduce cognitive load and make animations more accessible. While many ideas are related to the user interface design with the implicit or explicit goal to minimize split attention and/or maximize user control [9][10][11][12][13][14], others focus on the transition between time-steps [15,16], on techniques to highlight important changes [17], or on the relation between data complexity and animation speed. Multimäki and Ahonen-Rainio [18] equalize the temporal scale according to the temporal density of change, slowing down the animation in busy times, while increasing animation pace when the number of changes is low.…”

Użyteczność geowizualizacji wieloelementowych w kontekście semiotyki kartograficznej

“…W kontekście map animowanych analogiczne badania przeprowadzili P. Cybulski i B. Medyńska-Gulij (2018). Autorzy użyli zmiennych grafi cznych wielkości oraz barwy do zakodowania danych o odniesieniu punktowym (wielkość opadów atmosferycznych, ryc.…”
