  • A picture is worth 1,000 words refers to the idea that a complex idea can be conveyed with just a single still image. It also aptly characterizes one of the main goals of visualization, namely making it possible to absorb large amounts of data quickly.
  • Reference model for visualization. Visualization can be described as the mapping of data to visual form that supports human interaction in a workspace for visual sense making.
  • Bandwidth of the senses – convert that notion into computer terms – Tor Norretranders is a Danish scholar
  • You have two choices: use one of the  existing data sets    on the site, or Upload your own data set - After you choose a data set, you must choose a visualization method. Many Eyes provides a variety of visualization methods. Analyse text, see the relationships associated with part of the data, see relationships among different variables, track rises and falls in data over time.
  • Choose text to analyse – choose tool to run (find word patterns, view word use, trends in word use)

      • Why Twitter?
    • Information visualisation
      • What is it?
      • Why should I visualise?

    • The future
  • 3. What is social media?
  • 4. One Definition (boyd & Ellison, 2007)
    • Web-based services that allow individuals to:
      • construct a public or semi-public profile within a bounded system;
      • articulate a list of other users with whom they share a connection ; and
      • view and traverse their list of connections and those made by others within the system.

  • 5. Why is social media valuable?
    • Increase communication
    • Increase feelings of connectivity
    • Increase online learning community
    • Increase learning
  • 6. http://twitter.com
  • 7.  
  • 8. Why Twitter?
    • Microblogging (140 characters)
    • Easy-to-use
    • Push down communication
    • Not email
      • Zero clutter
      • Students  social media > email (Roblyer et al., 2010)
    • Personal Learning Network (PLN)
      • Learning through connections
      • Connectivism (Siemens, 2004)
  • 9. Definitions (Card et al., 1999, p. 7)
    • Visualisation:
    • The use of computer-based, interactive visual representations of data to amplify cognition.
    • Information visualisation:
      • The use of interactive visual representations of abstract, nonphysically based data to amplify cognition.
  • 10. What is information visualisation?
    • Robertson, Card, & Mackinlay (1989)
      • First use of the term “information visualisation”
      • Cognitive amplification, interactivity, animation
    • Represent data – visual form
    • External cognition aids
      • Maps, charts, graphs, diagrams
      • Text clouds, animations
      • Social media relationships (e.g., Hansen, 2011)
      • Mashups (e.g., Google Maps/Google Earth)
  • 11. “ Evolution” of Information Visualisation
  • 12. Information Visualisation = Mainstream
    • Today’s tools
      • Free, interactive
      • Bring data to non-experts
    • Journalists
      • NY Times
      • http://tinyurl.com/45md7ur
    • Artists
      • Brooke Singer
      • Databody
      • http://www.bsing.net/databody.pdf
  • 13. Q: WHY SHOULD I VISUALISE?
  • 14. A Picture is Worth 1,000 Words Pictures can attract attention faster than other media (Barnard, 1927)
  • 15.  
  • 16. Reference Model for Visualisation (Card et al., 1999, p. 17)
  • 17. The Language of the Eye
    • The User Illusion (1999)
    • Sight  faster
      • Bandwidth
      • Computer network
    • Better understanding
      • Eye
      • Mind
  • 18.

  • 19. TMI: Too Much Information
    • Twitter users (e.g., Rao, 2011)
      • 572,000 accounts  created on March 12, 2011
      • 460,000 (ave.) new accounts/day
      • Mobile users are up 182% from 2010
    • Tweets – the numbers
      • 140 million Tweets (ave.)/day
      • 50 million Tweets sent per day, a year ago 
      • Record tweets = 177 million  March 11, 2011
  • 20. Visualising Twitter Traffic http://vimeo.com/11302556
  • 21. Visualisation = Data Compression
    • David McCandless, 2010
    • Data is the new oil
    • Or is data the new soil?
      • Fertile
      • Well-tilled medium
      • Visualisations = data flowers
  • 22. Education-related Reasons to Visualise
    • Insight (not pictures)
      • New way to see & experience information
      • Hidden patterns, connections = revealed
      • Narrative = clarified
    • Amplify cognition - sense making (Card et al., 1999; Larkin & Simon, 1987)
    • Self-organising maps = brain organisation
    • Integrate offline-online experiences
    • Digital & critical competencies
