Visual analytics aims to combine the strengths of human and electronic data processing. Visualisation, whereby humans and computers cooperate through graphics, is the means through which this is achieved. Seamless and sophisticated synergies are required for analysing spatio-temporal data and solving spatio-temporal problems. In modern society,(More)

Methods for interactive map animations are still in an early stage compared to more traditional cartography, and the potentials for improvements are significant. This paper focuses on better design for map animations, particularly for the portrayal of the information regarding the temporal dimension. A series of animations are presented and discussed and(More)
Spatializations are computer visualizations in which nonspatial information is depicted spatially. Spatializations of large databases commonly use distance as a metaphor to depict semantic (nonspatial) similarities among data items. By analogy to the " first law of geography " , which states that closer things tend to be more similar, we propose a " first(More)
Visual analytics is often based on the intuition that highly interactive and dynamic depic-tions of complex and multivariate databases amplify human capabilities for inference and decision-making, as they facilitate cognitive tasks such as pattern recognition, association, and analytical reasoning (Thomas and Cook 2005). But how do we know whether visual(More)
The landscape metaphor was one of the first methods used by the information visualization community to reorganize and depict document archives that are not inherently spatial. The motivation for the use of the landscape metaphor is that everyone intuitively understands landscapes. We critically examine the information visualiza-tion designer's ontologies(More)
Information visualizations have become popular tools for extracting knowledge from large bodies of information. Very little is known on the usability of such 'visual knowledge tools' for information access. The goal of this paper is to show the usability of the spatial metaphor 'scale' to access a large semantic document space. An experiment was conducted(More)
We propose an empirical, perception-based evaluation approach for assessing the effectiveness and efficiency of longstanding cartographic design principles applied to 2D map displays. The approach includes bottom-up visual saliency models that are compared with eye-movement data collected in human subject experiments on map stimuli embedded in the so-called(More)
