SpatialRugs : Enhancing Spatial Awareness of Movement in Dense Pixel Visualizations

2020-03-27T08:53:09Z, Buchmüller, Juri F., Schlegel, Udo, Cakmak, Eren, Dimara, Evanthia, Keim, Daniel A.

Compact visual summaries of spatio-temporal movement data often strive to express accurate positions of movers. We present SpatialRugs, a technique to enhance the spatial awareness of movements in dense pixel visualizations. SpatialRugs apply 2D colormaps to visualize location mapped to a juxtaposed display. We explore the effect of various colormaps discussing perceptual limitations and introduce a custom color-smoothing method to mitigate distorted patterns of collective movement behavior.
