Many users are overloaded by the number of webpages they use simultaneously. We introduce TabFour, a prototype web browser which integrates three features that address the design requirements identified in an initial design study. Webpages can be grouped into tasks, providing
a unified target for resumption after an interruption. Tasks and pages can be annotated, supporting
resumption after longer intervals. Finally, tasks can be shared through a simple yet novel web-service, allowing users to share groups of webpages more easily than with existing tools.

  • 6. Problem Information overload
  • 7. Redesign
    • Review: A task-focused browser interface
      • Suspension and Interruption
      • Annotation
      • Sharing
  • 8. Redesign
    • Lessons from Phase II
      • Paper prototype generally well-received
        • Excitement about ideas
        • Generally kept all features
        • Two key points . Default hiding of task management features . Transparent sharing
  • 9. Redesign
    • Worries about sharing feature
      • But still keen on easier sharing
      • Originally just attach/send files
        • What if there’s an error? What if they can’t open it?
        • What if versions change?
      • Software isn’t even written and already they don’t trust it!
    • Replaced with drag-n-drop and added cloud sharing
  • 10. Redesign Drag & Drop
  • 11. Redesign Drag & Drop “ The internet” Share Load Entire context is loaded!
  • 12. Implementation
    • Firefox plugin vs Flex prototype
      • Practical significance vs. practicality for CS544
    • Subset of features: vertical prototype
      • Annotation
      • Suspension and Resumption
      • Sharing
  • 13. Implementation
  • 14. Evaluation Procedure
    • Extended use of prototype not feasible
    • 8 subjects, c omparison with FireFox
      • Very minimal training session
    • Short (& intensive!) multi-tasking scenarios
      • Interruption
      • Suspension
      • Resumption
      • Sharing
  • 15. Evaluation Procedure
    • Primary Task
      • Trip planning with hypothetical friend
        • “ Mark” or “Jane” – same sex as subject
    • Communications through Email and IM
    • Interrupts through IM
      • Add secondary tasks
        • Extra details to primary task (sightseeing)
        • Interruption of primary task (research papers)
  • 16. Evaluation Procedure
    • Questionnaires and short discussion
      • Work load of assigned tasks
        • Immediately after trial
        • 7 point Likert scale
      • Comparisons between browsers and general questions
        • At end of session
  • 17. Results
    • Quantitative analysis of data
    • NASA TLX-like
      • Used Wilcoxon test, Bonferroni corrected
      • All task load questions non-significant, p > 0.1
      • Still, 6/8 rank TabFour higher for question: “How effectively did the browser interface support what you were asked to do”?
  • 18. Results
    • Quantitative analysis of data
    • Other questions mostly unanimous:
      • Which browser was easier to use to complete the tasks? -TabFour
      • Did you find the task-based browsing useful? –Yes
      • Would you use task-based browsing if it was available in your regular web browser? –Yes
      • In which browser was it easier to share webpages with other people? -TabFour
  • 19. Results
    • Qualitative feedback
      • Usability issue on Load/Share context dialog
      • More organized in TabFour
      • Integration with existing tools desirable
        • Want to click links/task names in email
      • What if Mark gives me a bad link (typo)?
      • “ Simple, doesn’t require extra learning to use”
  • 20. Results
    • Qualitative feedback
      • “ FireFox lets you see things all at once”
      • Benefits and costs more obvious in prolonged use?
      • “ Task groups cut down on time needed to complete tasks”
  • 21. Demo + Video Code: http://code.google.com/p/tabfour/ Video: http://vimeo.com/9088447
