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 real-time 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.
