Abstract

Visualization is concerned with the design and implementation of algorithms for creating images that can facilitate our understanding of a set of data. My research in visualization draws broadly from work in perceptual psychology, art, computer graphics and computer vision, and is loosely organized around the central philosophy that there is a definable science behind the art of effective visual representation, a fundamental theoretical basis for knowing how to map data to pictures in a way that allows the important information to be easily and accurately understood. In this talk I will give an overview of some of my recent research in information representation, emphasizing fundamental issues in choosing promising methods and in evaluating their effectiveness. Two of the specific applications I will discuss include: using color and texture to simultaneously convey multiple scalar distributions over a 2D map, and using texture to facilitate the accurate and intuitive understanding of the 3D shape of a smoothly curving surface.
