A: Yes • Guiard, 1987: NPH defines frame of reference. • Right vs. Left is the wrong question to ask.
What is the logic of the division of labor between pen and touch in interface design?
Pen Writes Touch Manipulates
fluidity of annotation + • manipulation • navigation • zooming • object creation
PEN + TOUCH GESTURES peel off copy staple Xacto cut straightedge brush stamp
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.
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.”
Not pen. Not touch.Not pen OR touch.Pen AND Touch, designed in concert
Why Pen? I can type faster. • It’s not the same message. • Different thought process: text mires you in detail.
