2011 GRC Visualization in Science and Education
Although I got back from the 2011 GRC Visualization in Science and Education conference Friday night, my brain still hurts (in a good way). Thanks to Liz and Ghislain for their superb job as conference chairs. To me, the theme of this year’s conference was salience (more precisely, perceptual salience)–the ability of our visual system to focus on one thing at a time, to the near exclusion of everything else.
Hold one hand out in front of you, with the thumb up, and focus on the thumbnail. This is the limit of your locus of attention: about one degree. Away from that point everything else in your visual field fades into the background. For data visualization this is both an advantage (you can draw people to the important parts of an image) and a drawback (it’s impossible to pay attention to two things at once, and it’s easy to have your focus shifted unintentionally).
I’ll have some examples, and interesting bits from the presentations and discussion, in the next few days and weeks.
