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.
