Q: Which hand do you write with, Right or Left?
![Page 15: A SHIFT TO](https://reader035.vdocuments.mx/reader035/viewer/2022070423/568166a4550346895dda91e1/html5/thumbnails/15.jpg)
A: Yes
• Guiard, 1987: NPH defines frame of reference.• Right vs. Left is the wrong question to ask.

between pen and touch in interface design?

• 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.

• 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:
REACTIONS FROM USERS
“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.”
