Portable terminal having software keyboard for note-recognition and note-recognition method by pen input

摘要

A portable terminal having a soft keyboard capable of handwriting recognition according to the present invention is a portable terminal for outputting information according to a pen input through a touch screen for detecting a user's touch on a displayed keyboard keyboard. The soft keyboard is configured to switch to the first mode or the second mode, and to input keys or write on the keyboard according to the sum of the height and width of the trajectory from the pen input point to the end point according to the keyboard keyboard mode setting. A main control unit controlling a mode of a keyboard keyboard and storing two different language codes necessary for recognizing the handwritten character to recognize the handwritten character; And a threshold for the sum of the height and width of the trajectory from the pen input time point to the end point in order to distinguish whether the keyboard key is input or written on the keyboard, and at the pen input time according to the pen input on the keyboard. And a memory for storing the trajectory data up to the end point, wherein the main control unit determines whether the trajectory data stored in the memory is a key or handwriting of a soft keyboard, and when the keyboard is pressed, the character set of the language on the keyboard. In the case of inputting the corresponding key value and writing, it calls the language character recognizer different from the current soft keyboard to input the recognition result character value.
