  • What the heck is …
    • Information Visualization (InfoVis)
    • - computer-supported,
    • - interactive,
    • - visual representations,
    • - of abstract data
    • … to amplify cognition
  • This is an InfoVis tool From: www.londonair.org.uk/london/asp/virtualmaps.asp
  • This is NOT InfoVis tool http://www.flickr.com/photos/gdsdigital/4514262548/
  • Communicating visually

  • Evaluating InfoVis
    • Challenge one:
    • What are the evaluation criteria ?
  • Evaluating InfoVis
    • Challenge one:
    • What are the evaluation criteria ?
    • Insight?
    • But how to measure it?
  • Evaluating InfoVis
    • Challenge two:
    • What evaluation methods to use?
  • Evaluating InfoVis Challenge three: Subjectivity of the InfoVis experience
  • Summary
    • Visual communication is powerful
    • - More InfoVis tools in future
    • InfoVis designs need validating
    • “ just because it’s graphical, doesn’t mean it’s useful”
    • Evaluating InfoVis experience is problematic
    • - We need specific evaluation methods and performance criteria
