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

    • Visualization systems as navigational aids around the web of personal information Mohan Raj R, CPSC 533c 2009W
    • Mindmaps in a browser ? 2
    • Outline A Survey:● Brief view of existing systems● Design implications from studies of information organization systems● Future work 3
    • Existing systems That have characteristics of my ideal system Padprints Footprints WebForager, WebBook DataMountain ScratchPad InsightFinder 4
    • Structural, Spatial navigational support 5
    • 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
    • FootPrints Collective foraging 7Alan Wexelblat , Pattie Maes, Footprints: history-rich tools for information foraging, 1999
    • DataMountain 8Robertson et al., Data mountain: using spatial memory for document management, 1998
    • Web forager 9Stuart Card et al, The WebBook and the Web Forager: an information workspace for the World-Wide Web, 1996
    • Semantic navigational support 10
    • ScratchPad 11Gotz, D. 2007, The ScratchPad: sensemaking support for the web
    • InsightFinder Context based recommendationCheng, W. and Gotz, D. 2009. Context-based page unit recommendation for 12 web-based sensemaking tasks
    • InsightFinder Context based recommendationCheng, W. and Gotz, D. 2009. Context-based page unit recommendation for 13 web-based sensemaking tasks
    • 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
    • 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
    • Thank you 16
    • Bookmarking in nature 17
    • 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
