16 Stages of Processing Preattentive Processing Visual Integration Cognitive Integration

17 Visual Integration Chartjunk Data/Ink Ratio

18 Mobilising Visual Integration Affordance Highlighting – bright colours Increasing Intensity = Increasing Values Eye Tracking Studies Eye Path going from cluster to legend, and back again (Ratwani, 2008)

19 Mobilising Visual Integration Sequential Palettes Diverging Palettes Qualitative Palettes

20 Visual Integration

21 Stages of Processing Preattentive Processing Visual Integration Cognitive Integration

22 Building an understanding of the graph Eye Tracking Studies Eye Path going from cluster to cluster, rather than cluster to legend (Ratwani, 2008)

23 Cognitive Integration Summary first Zoom and filter Then details on-demand (Schneiderman, 1999)

24 Cognitive Integration Comparison Sorting Bookmarks – analytical view of browsing

25 Mobilising Cognitive Integration Humans are not good at judging: 2D Area Angles

26 Mobilising Cognitive Integration Humans are not good at judging: 2D Area Angles Pie Charts and Gauges rely on these characteristics…
