Handwritten data capture method and handwritten data capture device

A handwritten data capture method that creates a plurality of pieces of stroke data, the handwritten data capture method comprising:

• acquiring a plurality of pieces of handwritten data created based on writing performed on a plurality of pages included in a paper medium and based on a writing order, wherein each of the pieces of handwritten data includes coordinate data indicating a position of an electronic pen on a sensor, pressure information indicating a pressure applied to a tip of the electronic pen, and timestamp information indicating a time value;
• determining whether each of the pieces of handwritten data indicates that the electronic pen has a pen-down status or a pen-up status, wherein, when the pressure information included in a piece of handwritten data does not indicate that the pressure applied to the tip of the electronic pen is zero, the piece of handwritten data is determined to indicate that the electronic pen has the pen-down status, and when the pressure information included in the piece of handwritten data indicates that the pressure applied to the tip of the electronic pen is zero, the piece of handwritten data is determined to indicate that the electronic pen has the pen-up status;
• storing M pieces of stroke data, wherein each of the M pieces of stroke data includes the coordinate data of at least one of the pieces of handwritten data that is determined to indicate that the pen has the pen-down status, wherein the coordinate data of the pieces of handwritten data that are determined to indicate that the pen has the pen-up status are excluded from the stroke data, wherein the timestamp information of the at least one of the pieces of handwritten data indicates a time that is after a time indicated by the timestamp information of a first one of the pieces of handwritten data that is determined to indicate that the pen has the pen-up status, and that is before a time indicated by the timestamp information of a second one of the pieces of handwritten data that is determined to indicate that the pen has the pen-up status;
• assigning M order values to M pieces of stroke data, respectively, based on the timestamp information included in the handwritten data;
• displaying together on a display device the M pieces of stroke data based on the M order values assigned to the M pieces of stroke data;
• accepting an input of a break position of the M pieces of stroke data corresponding to one of the M order values, after acquiring the pieces of handwritten data created based on the writing performed on the pages included in the paper medium and based on the writing order;
• identifying a continuous portion of the M pieces of stroke data based on the break position by extracting one or more of the M pieces of stroke data, wherein the one or more of the M pieces of stroke data are assigned one or more of the M order numbers that are greater than the one of the M order values corresponding to the break position;
• updating the display device to display the identified continuous portion of the pieces of stroke data in the writing order;
• and
• repeating the accepting, the identifying, and the updating until a given operation is received.
