Abstract

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.
