Recording of information

Abstract

A product intended to be used in connection with the recording of information is provided. The product has a surface in which there are a plurality of different information alternatives, each having an associated code area. The surface is provided with a two-dimensional position code which codes coordinates for a plurality of positions on the surface in the code areas. The position code is unrelated to the information to be recorded. The surface permits recording of a desired information alternative by reading the position code for a position in the code area associated with the desired information alternative.

1 . A product intended to be used in connection with the recording of information and having a surface in which there are a plurality of different information alternatives, each having an associated code area, wherein the surface is provided with a two-dimensional position code which codes coordinates for a plurality of positions on the surface in said code areas and is unrelated to the information to be recorded, said surface permitting recording of a desired information alternative by reading the position code for a position in the code area associated with the desired information alternative.  
     
     
         2 . A product according to  claim 1 , wherein said position code codes the coordinates for a plurality of positions in at least one code area, so that the associated information alternative can be recorded by reading an arbitrary position in said at least one code area.  
     
     
         3 . A product according to  claim 1 , wherein the position code extends across the entire surface.  
     
     
         4 . A product according to  claim 1 , wherein the position code is optically readable.  
     
     
         5 . A product according to  claim 1 , wherein the product has the form of a sheet.  
     
     
         6 . A product according to  claim 1 , wherein said surface is provided with at least one writing area and wherein said position code overlaps the writing area and codes coordinates for a plurality of positions in the writing area.  
     
     
         7 . A product according to  claim 6 , wherein said writing area is associated with an information alternative and constitutes part of the code area of the information alternative.  
     
     
         8 . A system for recording information, said system comprising: 
 a product according to  claim 1;  and    a device for recording one of said plurality of information alternatives, said device including: 
 a sensor for reading the position code in the code area associated with said information alternative, and  
 processing means for interpreting the read code in order to identify the position which corresponds to the read code.
