UI for Big Data Visualization | Jonathan Stray | UX Week 2012

  1. interfaces for big data visualization jonathan stray overview project associated press
  2. Ben Fry, Computational Information Design
  3. visualization extends perception
  4. “Visualization allows people to offload cognition to the perceptual system, using carefully designed images as a form of external memory. The human visual system is a very high- bandwidth channel to the brain, Tamara Munzner with a significant amount of processing occurring in parallel and at the pre-conscious level.”
  5. a visualization turns something you want to find into something you can see
  6. clusters outliers extents correlations
  7. work with human perception
  8. work with human senses work with human memory work with human cognition
  9. you have never seen a violin. perception involves interactively directing narrow attention
  10. don’t show it all. (you can’t anyway)
  11. filter
  12. summarize
  13. categories = “distance metric” + clustering algorithm d(x, y) ≥ 0 d(x, x) = 0 d(x, y) = d(y, x) d(x, z) ≤ d(x, y) + d(y, z) k-means single link hierachical
  14. annotate
  15. snapshots tags notes history
  16. demo the overview project
  17. the world does not spring magically into our heads. neither does big data. Interface extends perception. thanks @jonathanstray
