Abstract
A touch system includes a touch panel having a touch surface and a projector for projecting 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 the images presented on the touch surface reflect the pointer activity. The computer executes a gesture responsive ink injection routine to detect when a selected gesture is made with the pointer on the touch surface. The gesture responsive ink injection routine performs recognition to convert ink drawn on the touch surface into a form suitable for the applications program when the selected gesture is recognized and enters the recognized text into the application.
