Abstract

This paper describes three experiments that investigate the ability of humans to perform high-speed visual estimation. This work is part of an ongoing study of techniques which allow rapid and accurate visualization of large multidimensional datasets. Scientific visualization in computer graphics is a relatively new field of research. The term "visualization" was used by a 1987 panel sponsored by the National Science Foundation (NSF) discussing how to apply computer science to data analysis problems (McCormick et al., 1987). The panel defined the "domain of visualization" to include the development of general purpose tools and the study of research problems that arise in the process. A variety of methods have been used to convert raw data into a more usable visual format. Both Tufte
