An electronically stored document which can be of any type such as text, image, drawing etc. is printed on a surface, preferably a sheet of paper, which is provided with a position-coding pattern. Manual editing is then carried out on the printout surface with a digital pen which comprises means for reading the position-coding pattern and also a pen point for marking on the surface. Editing is done by means of a code which is in the form of symbols from a predetermined set of symbols, on the sheet of paper. The editing information, i.e. the symbols applied to the surface, is digitally registered by the digital pen and transferred to the storage and processing device, preferably a computer. This transfer can be done directly during the editing or on a later occasion. Interpretation of the editing code is then carried out, wholly or partly in the computer, in interaction with the document stored in the computer, whereupon changes are made to the stored document in direct dependence on the interpretation. |
