Visualization as “Cognitive Enhancement“

  • Increased memory/ processing resources
  • Reduced search time
  • Enhanced pattern recognition
  • Perceptual inference (much faster than logical)
  • Use of perceptual attention mechanisms for monitoring
  • Encoding information in a manipulable form

——Stuart Card et al. reading in information

Visualization: using vision to think (Morgan Kaufman, 1999)

 

Visualization—insight

  • We discover unimagined effects, and we challenge imagined ones

——William Cleveland, Visualizing Data (1993)

  • I see it now. Aha!

——Martin Wattenberg, on data visualization (2007)

  • It “forces” us to see

——Stephen Ramsay, “In Praise of Pattern”(1995)
