  11. OF HANDSANDHANDEDNESS

  12. Q: Which hand do you write with, Right or Left?

  13. A: Yes • Guiard, 1987: NPH defines frame of reference. • Right vs. Left is the wrong question to ask.

  14. What is the logic of the division of labor between pen and touch in interface design?

  15. Pen Writes Touch Manipulates

  16. fluidity of annotation + • manipulation • navigation • zooming • object creation

  17. Pen + Touch Yields New Tools

  18. Video

  19. PEN + TOUCH GESTURES peel off copy staple Xacto cut straightedge brush stamp

  20. SOME INTRIGUING PROPERTIES… • Holding touch integrates Object Selection and Pen Mode Switching into a single action. • Holding object… • provides salient feedback of temporary state. • unambiguously phrases together multiple elementary pen and touch inputs. • Extends the space of interactions w/out hitting heavyweight modes & ambiguities. • No physical buttons (NPH modes…) • Minimal on-screen UI & widgets.

  21. INFORMALUSERSTUDY

  22. REACTIONS FROM USERS • Users easily interleaved pen & touch – obvious • Staple, Xacto Cut, and Peel off Copy particularly resonated with users • The particular tools were not always of interest • Some example comments: • “The way it works is just like the way I already work in my notebook.”“I wouldn’t have guessed the gestures worked that way, but once I tried it, it felt pretty natural.”

  23. SUMMARY

  24. Not pen. Not touch.Not pen OR touch.Pen AND Touch, designed in concert

  25. Why Pen? I can type faster.

  26. Why Pen? I can type faster. • It’s not the same message. • Different thought process: text mires you in detail.

  27. In other words…

  28. devices without buttons…
