Transcript of "Visualization systems as navigational aids around the web of personal information"

  1. 1. Visualization systems as navigational aids around the web of personal information Mohan Raj R, CPSC 533c 2009W
  2. 2. Mindmaps in a browser ? 2
  3. 3. Outline A Survey:● Brief view of existing systems● Design implications from studies of information organization systems● Future work 3
  4. 4. Existing systems That have characteristics of my ideal system Padprints Footprints WebForager, WebBook DataMountain ScratchPad InsightFinder 4
  5. 5. Structural, Spatial navigational support 5
  6. 6. PadPrintsHightower, R. R., Ring, L. T., Helfman, J. I., Bederson, B. B., and Hollan, J. D. 1998. 6Graphical multiscale Web histories: a study of padprints
  7. 7. FootPrints Collective foraging 7Alan Wexelblat , Pattie Maes, Footprints: history-rich tools for information foraging, 1999

  11. 11. ScratchPad 11Gotz, D. 2007, The ScratchPad: sensemaking support for the web
  12. 12. InsightFinder Context based recommendationCheng, W. and Gotz, D. 2009. Context-based page unit recommendation for 12 web-based sensemaking tasks
  13. 13. InsightFinder Context based recommendationCheng, W. and Gotz, D. 2009. Context-based page unit recommendation for 13 web-based sensemaking tasks
  14. 14. Design implications Visibility (and reminding) Integration with existing work-flow Co-Adoption (affordance for people who work as a group to adopt the system) Scalability (with respect to the type or amount of information that the user wants to process) Return on InvestmentJones, E., H. Bruce, et al. (2008).I Give Up! Five Factors that Contribute to theAbandonment of Information Management Strategies 14
  15. 15. Future workAssociate information scents with resources indicating:1. The cost of foraging a resource URLs, for example2. The chances that it will be eventually used as intended Bookmarks, for example based on your history with other pieces of similar information based on the informations history with other similar peoplePrevent us from becoming information gluttons ! 15
  16. 16. Thank you 16
  17. 17. Bookmarking in nature 17
  18. 18. Spatial memoryClarks nutcracker :  buries 30k seeds across an area of 100 sq.miles  places a stone on top of the stash  recovers 70% of the nuts buried under several feet of snow  278+ days  But human spatial memory is limited to around 10 objects and suitable only for short-term 18
