METHOD OF RECORDING INFORMATION USING FIRST AND SECOND POSITION CODES
First Claim
1. A method for recording information from a surface of a substrate, said substrate being provided with a first position code which codes locations of a plurality of first points, and which, in one more zones, is further provided with a second position code which codes locations of a plurality of second points, the method comprising:
- obtaining an image of the surface of the substrate using an optically imaging pen;
determining whether the first position code or the second position code is present in the image;
determining at least one location of the pen using the imaged first position code or the imaged second position code; and
if the first position code is detected in the image;
interpreting said at least one location as handwritten input on said surface;
orif the second position code is detected in the image;
determining, on the basis of the second position code, whether the pen is placed in one of said zones on the surface; and
performing a predetermined function associated with said zone.

Abstract
A method for recording information from a surface of a substrate. The substrate is provided with a first position code and a second position code. The method comprises: (i) obtaining an image of the surface of the substrate using an optically imaging pen; (ii) determining whether the first position code or the second position code is present in the image; and (iii) determining the location of the pen. If the first position code is detected in the image, then the location is interpreted as handwritten input on the surface. Alternatively, if the second position code is detected in the image, then the location is used to determine if the pen is in a particular zone of the surface and a predetermined function associated with the zone is performed.
