VISFILES Confessions of a Visualization Skeptic Bill Hibbard Space Scienceand Engineering Center University of Wisconsin - Madison There is no doubt that visualization is indeed a very useful technology, enabling people to understand the masses of data and information otherwise hidden deep within computers. However, after many years developing visualization systems, I have to confess to skepticism about some of the hottest (i.e., coolest) visualization ideas.Your comments and thoughts on this column are welcome, as are your suggestions for future columns. Virtual Reality When I started at the Space Science and Engineering Center (SSEC) in 1978, they were already experimenting with red-green stereo viewing of pairs of images from satellites over the eastern and western United States. These gave viewers a qualitative feel for the altitudes of clouds.While these displays were very interesting, they never became the basis for serious work because scientists were not prepared to make quantitative judgments based on their depth perception. Instead, they developed algorithms for estimating the altitudes of cloud tops from these image pairs.Their primary serious use of visualization was to pick likely candidates for their automated cloudtracking algorithms, and to check the quality of the resulting wind estimates. Those tasks required
