Abstract
A touch system includes a touch panel having a touch surface and a projector presenting images onto the touch surface. A computer executing an applications program is coupled to the touch panel and the projector. The computer is responsive to contact output generated by the touch panel in response to proximity of a pointer to the touch surface and updates image data conveyed to the projector so that images presented on the touch surface reflect pointer activity. The computer executes a gesture connector recognition routine. The gesture connector recognition routine performs recognition to convert a freehand connector on the touch surface into a computer-generated connector approximating the freehand connector.
