Zusammenfassung
In this paper we present a novel rear-projection tabletop
called Touch & Write. It combines the FTIR technology for
touching with the Anoto-technology for handwriting. This
allows an implicit switch between the modes object manipulation,
and content editing. Our system incorporates realtime
gesture and handwriting recognition. Drawn objects
and written concepts can be converted to digital information
immediately. We introduce a functional application,
the LeCoOnt concept mapping software makes use of the
full capability of the Touch & Write table. Touching actions
are used for arranging the concepts like sheets on a normal
table, and to recognizes guestures like zooming. Pen-actions
are used for drawing, connecting concepts, and handwriting.
The handwritten strokes are automatically recognized and
converted into a machine-readable string. This system provides
a reliable alternative to common approaches which try
to reconstruct the information from photographs.
