It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Referring to FIG. 1 , the present invention provides a handwriting input system for handwriting input. The system 100 can be a software unit, a hardware unit or a combination of software and hardware built in the handwriting input device. 2, the handwriting input system 100 has a display screen 101, and the system 100 also includes a handwriting input module 10, a matching module 20, a display module 30, and a selection module 40, wherein:

The handwriting input module 10 has an input area 11 on the display screen 101 for accepting handwriting input including handwriting input. Referring to Fig. 2, the input area 11 is divided into four areas: upper left, lower left, upper right and lower right, that is, the input area 11 is a "Tian"-shaped structure, and each area of the input area 11 can accept user's handwriting input.

The matching module 20 is used to match at least one Chinese character according to all completed handwritings after each input handwriting is completed. In a specific application, every time the user completes an input handwriting in the input area 11, the matching module 20 performs Chinese character matching on all the input handwritings. For example, when the user first inputs "one" in the middle of the input area 11, the matching module 20 performs Chinese character matching processing on the handwriting, such as matching Chinese characters "one", "three", "ten" according to the degree of proximity, and Handed over to the display module 30 for processing. At this time, if the user inputs the second "|" again to form the word "ten" with the first stroke, then the matching module 20 matches the Chinese characters associated with the word "ten", such as matching to obtain "ten", "earth", "dry" " and other Chinese characters are handed over to the display module 30 for display processing.

The display module 30 has a display area 31 on the display screen 101 for displaying matched Chinese characters, and the number of matched displayed Chinese characters can be determined according to the size of the display area 31 and the displayed font. As mentioned above, if the user finishes inputting the handwriting "one", after the processing by the matching module 20, the display module 30 will display matching Chinese characters such as "one", "three", and "ten" on the display area 31. When the user inputs When the second handwriting is completed, the display area 31 displays matching Chinese characters such as "ten", "earth", and "dry".

The selection module 40 is configured to receive a selection command of the matched Chinese character. After the display module 30 displays the matched Chinese characters in the display area 31 , the user can click to select the Chinese characters he needs, and the selected Chinese characters are displayed in the document area 51 of the display screen 101 .

In the embodiment of the present invention, the matching module 20 includes a judging submodule 21 and a matching submodule 22, wherein, in the process of the user inputting handwriting, the judging submodule 21 is used to judge all completed handwritings in the input area. Distribution state, the specific distribution state is that the handwriting structure is located in the upper left, lower left, upper right, lower right and middle positions, and it can also be a combined structure. According to the distribution of the "Tian" font, it is also judged as "upper" and "lower" according to different structures Combined state of "left" and "right". The matching sub-module 22 is used to match the closest Chinese characters according to the composition structure of all completed handwriting and the distribution state of the structure in the input area. 3A and 3B, when the user completes the handwriting "木" in the middle of the input area 11, the judging sub-module 21 judges that the handwriting "木" is located in the middle of the input area, and the matching sub-module 22 matches the associated Chinese characters. Displayed in the display area 31 by the display module, as shown in Figure 3B, if the user does not select a Chinese character within a predetermined time, the first character "wood" displayed in the display area 31 is automatically displayed in the document area 51.

Further, if the structure of all the handwriting completed by the user is distributed in the upper part (occupying the upper left and upper right areas at the same time) or the lower part (occupying the lower left and lower right areas at the same time) of the input area 11, the matching submodule 22 matches the structure associated If the structure of all the handwriting completed by the user is distributed on the left part of the input area 11 (occupying the upper left and lower left areas at the same time) or the right part (occupying the upper right and lower right areas at the same time), the matching submodule 22 matches Chinese characters of the upper and lower structures associated with said structure. 4A and 4B, when the user inputs the word "wood" in the upper part of the input area 11, the Chinese characters matched by the matching sub-module 22 are as shown in FIG. 4B, and the user can choose the Chinese character he needs. Better, the user can also select after inputting the handwriting of multiple structures, as shown in Figure 5A, the user inputs the trace of the word "木" in the left part of the input area 11, and then enters "夂" in the upper right area, then the matching character The Chinese character matched by the module 22 is shown as "grid" in Fig. 5B, so that the user can directly obtain the Chinese character.

It should be noted that, the system handwriting input module 10 of the present invention allows a certain error when receiving handwriting input, and the error range can be preset. For example, the user wants to input the first handwriting "一" in the middle position, but due to other reasons, such as shaking, the input handwriting is slightly higher or lower. If the deviation is within the error range, the system will still judge the handwriting It is the handwriting in the middle position, so as to increase the accuracy of input and make it more humane.

The present invention also provides a handwriting input device comprising the above-mentioned system 100, which may be, but not limited to, a mobile terminal, and the mobile terminal may be a mobile phone, a PDA (Personal Digital Assistant, a personal digital assistant), a palmtop computer, and the like. It has a higher handwriting input speed of the user, and the user experience is better.

Referring to Fig. 6, the present invention provides a kind of handwriting input method, and it can be realized by handwriting input system 100 as shown in Fig. 1, and this method comprises:

Step S601 , the handwriting input module 10 accepts handwriting input including handwriting input through its input area 11 . After the system 100 is started, the user can input handwriting in the "Tian"-shaped input area 11, specifically at the top, bottom, left, right or middle position, or a combination of all positions.

Step S602, after each handwriting is completed, the matching module 20 matches at least one Chinese character according to all completed handwritings. Specifically, after the user inputs the corresponding handwriting in the input area 11, the judging sub-module 21 judges the distribution status of all the handwritings that have been completed in the input area 11; The distribution state of the input area 11 matches the closest Chinese character. Further, if the structure of all the handwriting completed by the user is distributed in the upper or lower part of the input area 11, the matching submodule 22 matches the Chinese characters of the upper and lower structures associated with the structure; if the structure of all the handwriting completed by the user is distributed in the When the left or right part of the area 11 is input, the matching sub-module 22 matches the Chinese characters of the upper and lower structures associated with the structure.

In step S603, the display module 30 displays the matched Chinese characters in its display area 31 . In practical applications, when the matched Chinese characters are displayed, they are arranged according to the degree of similarity to the composition structure of all handwritings, and the one with the highest degree of similarity is ranked first. For example, when the user enters the handwriting "one", the arranged " One" ranks first, and "ten" ranks second, making it more convenient for users to choose.

After the matched Chinese characters are displayed on the display area 31 , the user can select the desired characters through the selection module 40 , and the selected Chinese characters will be displayed in the document area 51 .

In summary, the present invention receives the user's handwriting input in the input area of the device. The handwriting can be input by handwriting. Every time the user completes a handwriting, the system matches at least one Chinese character according to all the completed handwriting, and matches the matched Chinese character to display.
