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.

Claims

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.

2. The system of claim 1, wherein the processor resides externally of the pen.

3. The system of claim 1, wherein the processor is adapted to determine an identity of the surface using the interaction data.

4. The system of claim 1, wherein the second area is physically separated from the first area.

5. The system of claim 4, wherein at least one sub-area of the second area comprises a label representing a property for a freeform graphic.

6. The system of claim 4, wherein at least one sub-area of the second area comprises an indication of a color for a freeform graphic.

7. The system of claim 4, wherein at least one sub-area of the second area comprises an indication of a line style for a freeform graphic.

8. The system of claim 1, wherein said pen comprises a nib and a force sensor for detecting when said nib is in contact with said surface.

10. The system of claim 1, which includes said processor.
