Abstract
A touch system comprises 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 suggestion and writing recognition routine. The gesture suggestion and writing recognition routine performs recognition to convert ink on the touch surface into another object based on a selected interpretation.
