Abstract
An interactive document processing system includes a display screen that is coupled to a processing device. In addition, the document processing system includes an input device for viewing all or a portion of a hardcopy document on a work surface. The input device generates signals representing the appearance of the hardcopy document from representative electronic data stored in a print memory. In one embodiment, the processing device is connected to the input device to receive the signals, determine the position of a moving indicator relative to the document, and correlate the determined position with the electronic representation of the hardcopy document. The display screen provides information related to user commands that edit and/or select portions of the electronic representation of the hardcopy document.
