  2. Pen-Based Interfaces • Great for notes, sketches • Lack of shortcuts problematic

  3. Pen-Based Interfaces • Great for notes, sketches • Lack of shortcuts problematic • Round trip problem

  4. Localized User Interfaces • Gesture Interaction • Tivoli (Moran, Chiu, Melle. UIST ’97) • SKETCH (Zeleznik, Herndon & Hughes. SIGGRAPH ’96) • DENIM (Newman, Lin, Hong & Landay. HCI ’03) • Menu Interaction • Marking Menu (Kurtenbach & Buxton. CHI ’93) • Flow Menu (Guimbretière & Winograd. UIST ’03) • Scroll ring (Smith & schraefel. Moscovich & Hughes. UIST ’04) • Hybrid • Scriboli (Hinckley, Baudisch, Ramos, & Guimbretière. CHI ’05)

  5. Localized User Interfaces • Gesture Interaction • Ink confused with gesture • Explicitly switch with button • Menu Interaction • Activated with button

  6. Localized User Interfaces

  7. Localized User Interfaces

  8. Localized User Interfaces

  9. Design Challenge • Localized user interface • Clearly distinct from ink input • No button required

  10. Tracking menus Fitzmaurice G., Khan A., Pieke R., Buxton B., Kurtenbach G.UIST 2003

  11. Hover Widgets • Gesture in tracking state • Widget fades in • Click on widget

  12. Hover Widgets

  13. Design Considerations • Shape

  14. Design Considerations • Shape • Recognition

  15. Design Considerations • Shape • Recognition • Visualization

  16. DEMO

  17. Experiment

  18. Independent Variables • Technique (Hover Widget, Icon) • GridN (4, 8, 12) • Distance (300, 600, 900, 1200)

  19. Results • Reduced Movement Time

  20. Results • Reduced Movement Time • Increased Accuracy

  21. Summary • New distinct command layer • Button free • Localized UI • Reduce time • Minimal shift of attention

  22. Future Work • Customize & adapt

  23. Future Work • Customize & adapt • Large displays
