Digitizing system having printed base, imaging pen and relay device
First Claim
1. A system for digitizing a freehand graphic, the system comprising:
- (A) 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;
(B) an optically imaging pen comprising;
the optical sensor for detecting a position in the position-coding pattern; and
communication means for wirelessly communicating interaction data to a relay device, said interaction data identifying the detected position;
(C) the relay device, said relay device being configured for communicating the interaction data to a processor,wherein said processor is adapted to perform the following actions;
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 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 with first and second areas. The system further comprises an optically imaging pen including for detecting a position in the position-coding pattern; and a transmitter for transmitting interaction data to a relay device. The relay device communicates the interaction to a processor, which 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.
