Abstract
Pen computing devices provide a natural interface for annotating
documents with freeform digital ink. However, digital ink annotations
are usually larger and sloppier than real ink annotations on paper. We
present DIZI, a focus+context interface that zooms up a region of the
underlying document for inking. Users write in the zoomed region at a
comfortable size for the device. When the zoom region is shrunk back
to normal page size, the digital ink shrinks to an appropriate size
for the underlying document. The zoom region covers only a small
portion of the screen so that users can always see the overall context
of the underlying document. We describe several techniques for fluidly
moving the zoom region to navigate the document. We show that DIZI
allows users to create digital ink annotations that more closely mimic
the look of real ink annotations on physical paper.
