  First, the control unit 105 reads the handwriting of characters input from the touch panel using a touch pen or a finger, the time when the touch pen or finger touches the touch panel and stops, the angle at which the touch pen or finger is bent, the touch panel moving Based on the input information including how to leave, the final writing of the input characters is analyzed using the final writing processing judgment criteria (see Fig. 2) including stop, splash, and hail. Based on this, a final writing process for changing the final writing of the handwriting is performed, and characters related to the handwriting whose final writing has been changed are displayed on the display unit 102 (see FIG. 3).

  Here, for example, in the case of “Circle”, the determination criterion for the final writing process is determined by the touch pen or fingertip being stationary on the touch panel screen for a certain period of time or more (see FIG. 2). The “Splash” part appears on the screen when the touch pen or fingertip that was moving on the touch panel screen is bent at an angle greater than a certain angle, and the touch pen or fingertip is moving on the touch panel screen. It is determined by leaving. Furthermore, the “Harai” part is displayed when the touch pen or fingertip that was moving on the touch panel screen is bent at an angle less than a certain angle, and the touch pen or fingertip is moving on the touch panel screen. Determined by leaving the screen.

  In addition, in the final stroke processing, the characters at the end of the stroke and the end of the stroke are not known before processing, but after the processing, the characters at the end of the stroke and the stroke are understandable. (See FIG. 3).

  In addition, the control unit 105 saves the input handwriting, stroke order, and information related to the last stroke in the storage unit 107 (see FIG. 4).

  In addition, the control unit 105 includes information related to the handwriting, stroke order, and final stroke of characters stored in the storage unit 107, and information related to the handwriting, stroke order, and final stroke of characters stored in the dictionary unit 109.
