Electronic device, handwriting input recognition system, and method for recognizing handwritten input thereof

An electronic device comprising:

• a touch screen;
• and
• a handwriting input system;
• wherein the handwriting input system comprises:
• a touch recognition module, configured to recognize an initial touch point of a touch and handwritten inputs on the touch screen;
• an input region determination module, configured to determine an input region associated with the initial touch point;
• a handwriting display module, configured to control to display the input region, and display the recognized handwritten inputs in the input region;
• a letter recognition module, configured to recognize a string of letters associated with each of the handwritten inputs in the input region;
• a determination module, configured to determine whether one of the handwritten inputs reaches one boundary of the input region, and also determine whether the input region receives one other handwritten input during a predefined time duration if the one of the handwritten inputs reaches the boundary of the input region, wherein the other handwritten input is follows the one of the handwritten inputs which reached the boundary of the input region, and there is no user operation between the following other handwritten input and the handwritten input which reached the boundary of the input region;
• the determination module being further configured to determine a string of letters which is associated with the handwritten input which reached the boundary of the input region is a first portion of a complete word and a string of letters associated with the other handwritten input is a last portion of the complete word if the input region receives the other handwritten input during the predefined time duration;
• a combination module, configured to combine the first portion and the last portion into a complete word and display letters of the first portion and the last portion in a substantially same size.

A handwriting input recognizing method applied to an electronic device having a touch screen, the method comprising:

• recognizing an initial touch point of a touch on the touch screen;
• determining an input region associated with the initial touch point;
• displaying the input region on the touch screen;
• recognizing and displaying a handwritten input in the input region;
• determining whether one of the handwritten inputs reaches one boundary of the input region;
• recognizing and displaying a string of letters associated with the handwritten inputs;
• determining whether the input region receives one other handwritten input during a predefined time duration if there is one handwritten input reaches the boundary of the input region, wherein the other handwritten input follows the one of the handwritten inputs which reached the boundary of the input region, and there is no user operation between the other handwritten input and the handwritten input which reached the boundary of the input region;
• determining the sting of letters which is associated with the handwritten input which reached the boundary of the input region is a first portion of a complete word, and the sting of letters associated with the other handwritten input is a last portion of the complete word if the input region receives the other handwritten input during a predefined time duration;
• combining the first portion and the last portion into a complete word and displaying letters of the first portion and the last portion in a substantially same size.
