System For Digitizing Freehand Graphics On A Printed Surface
First Claim
1. A system for digitizing a freehand graphic, the system comprising:
- a base including;
a surface;
a position-coding pattern printed on the surface and detectable by an optical sensor;
a first area of the surface; and
a second area of the surface;
a drawing device comprising;
an optical sensor for detecting a position in the position-coding pattern; and
communication means for communicating interaction data to a processor, said interaction data identifying the detected position;
wherein said processor is adapted to perform the following actions;
determining if the detected position is in the first area or the second area;
if the detected position is in the first area of the surface, then interpreting the position as a point in the freehand graphic; and
if the detected position is in the second area of the surface, then interpreting the position as a selection of a property for the freehand graphic.

Abstract
A system for digitizing a freehand graphic. The system comprises: a base including a surface; a position-coding pattern printed on the surface and detectable by an optical sensor; a first area of the surface; and a second area of the surface. The system further comprises a drawing device including an optical sensor for detecting a position in the position-coding pattern; and a transmitter for transmitting interaction data to a processor. The interaction data identifies the detected position. The processor is adapted to determine if the detected position is in the first area or the second area. If the detected position is in the first area of the surface, then the processor interprets the position as a point in the freehand graphic. If the detected position is in the second area of the surface, then the processor interprets the position as a selection of a property for the freehand graphic.
