ABSTRACT:
A system for generating new documents (20) from originals (4) containing text and/or images (22,28) employing e.g. a camera-projector system (6,8) focussed on a work surface (2), in conjunction with a copier or printer (14). In use, an original paper document (4) lying on the surface (2) becomes part of the interface to the copier machine as various interactions are carried out on the text or images (22,28). Feedback to the user is provided by projection of an image (21,24) onto the surface or onto the original, or using some other visual display. Text or images (22,28) may be selected and manipulated by the user, e.g. by pointing with fingers and tapping on the surface.
