  9. But Lo! A problem • Jump, go ahead and...

  10. Curvature Dial: for real value, eyes-free parameter entry - in particular for touch-screen input. - eyes-free extension for techniques like Guimbretiere and Winograd’s FlowMenus

  11. UIST05: the year of the dial • Radial Scroll (pre Curvature Drag) • Virtual Scroll Ring

  12. Comparison with Virtual Scroll Ring

  13. When Where and How The Pilot Studies Contributions by Pat, mc and Sacha Brostoff, Ray Cooke (Southampton) Tomer Mocovich (Brown)

  14. Questions • How do the techniques compare for stylus based computing? • How do they work on distinct platforms? • How do different distances effect?

  15. Things NOT looking at • How to invoke • How to go in multiple directions • Want to focus on where and what contexts are most appropriate • So…series of pilot studies

  16. Studies: Zoom and Scroll SCROLLING Compare Dialing techniques against scroll bars for scrolling: FACTORS: distance, platform ZOOMING Compare Dialing techniques against stroke (hand tool-like eyes free stroke): FACTORS: distance, platform

  17. Platforms

  18. Test Suite Compare Dial types for scrolling/zooming and variable distances

  19. Study 1: scrolling, smartboard Movement Time for scrolling task on Smartboard Error rates for the Smartboard task

  20. Lessons Learned: Study 1 • Scroll bars win on the large screen, but VSR significantly better than other dials • VSR more learnable: big distances, big circles seem more learnable than the Vernier approach of small circles • Problem with Vernier approach may be implementation issues

  21. Study 2: Scrolling/PDALong Distance Time Lessons Learned: PDA is a useful space for dialing - interesting trade-offs on error performances Errors

  22. Study 3: Zooming, Smartboard Errors Time Lessons Learned • Stroking has some interesting properties to explore: competes with VSR • Great performance, but people prefer VSR • Observe: short little multiple, rather than long strokes

  23. Study 4: Zooming, PDA Size Time Stroking more efficient; errors about the same; Virtual Scroll Ring preferred Errors

  24. Next Steps from studies • Curvature Dial against VSR (both non-accelerated) scrolling, four distances: Pick a winner and run with it • Winner accelerated vs. non-accelerated, again scrolling, four distances: pick a winner and run with it • Hand tool against accelerated hand tools: pick a winner • winner hand tool against winner dial • just scrollbar: four document lengths and three display sizes and four distances: where does it break • Winner incremental technique vs. scrollbar vs. combined technique, four document lengths and four distances, three display sizes

  25. Conclusions • Dialing is worth investigating for PDA’s especially • VSR is a strong favorite • Vernier needs to be revisited • Keep Checking: test suite will be updated regularly • Thoughts/ideas welcome
