Visualization for All (25 Jan 2002)
The use of graphics is a valuable technique for accessing information because it exploits the considerable power of human vision. History includes two well-known approaches: presentation--using vision to communicate--and visualization--using vision to think. Both approaches are being improved by the growing power of computer graphics.
In this talk, I reflect on my experiences over the last two decades using computer graphics to support these two approaches, and propose a new research direction that combines their strengths to make information more accessible to more people. Starting with presentation, I describe an early prototype that automatically designed 2D graphical presentations of relational data using a composition algebra and various design criteria. A key research goal was to design presentations that do not lie or mislead. Turning to visualization, I describe how the composition algebra was used to develop a series of prototypes for different types of data. A key research goal was to make large amounts of information accessible by using 3D graphics and interactive animation.
