Georeferenced statistical data
-
Abstract data on map (opposed to maps for navigation)
-
Some tasks can adequately be addressed with improved table tools
E.g. "Find the state with the maximum unemployement?" (sort function)
-
Others are very difficult with tables:
e.g. "Find global patterns, clusters, exceptions".
-
Expands on the work done on sonification of tables, graphs (see work of S. Brewster, J. Flowers, etc.)
-
In collaboration with: Ben Shneiderman, Ramani Duraiswami, Dmitry Zotkin (UMd, Spatial Sound Production) Barbara Shinn-Cunningham (BU, Sound Perception) and Ahmad Zaghal (UMd undergraduate student who is blind).
