Integration of pen input into interactive environments holds the
promise of gains in user friendliness and more natural interaction
styles than present direct manipulation tools can provide, since
handwritten gestures and pen strokes offer more expressive power
than the keyboard or mouse. However, penbased applications have yet
to enjoy widespread acceptance, because pen data are diffcult to
analyze due to noise, user variations and imprecise meaning.
Calligraphic interfaces is a term we have coined to designate a
class of pen based user interfaces in which handsketching or
drawing serves as the main organizational metaphor as opposed to
the point-and-click desktop metaphor commonly employed in current
graphical user interfaces. Our study of calligraphic interfaces
extends previous research in formal visual languages, syntactic
pattern recognition, and user interface design. Our
adjacency-driven parsing approach improves on previous research by
using adjacency-constraining relations to prune the search space
during intermediate analysis steps thereby yielding gains in
asymptotic complexity.
