Abstract

The present invention provides a method of increasing handwriting input efficiency, which first constructs a Chinese character library having a plurality of coding sequences of strokes of Chinese characters. Each coding sequence of strokes corresponds to the order of strokes of a Chinese character, and the stroke also corresponds to a basic font coding; when a partial stroke of a targeted character is inputted on a touch panel, the partial stroke could be those of discontinuous orders which can be converted into a subsequence including the basic character coding through using a processor, and therefore, such subsequence is compared with the stroke coding sequence in the Chinese character library to select those as candidate characters where the stroke coding sequence of Chinese characters is fitted with the subsequence. Finally, the candidate characters are displayed on a touch panel provided for selection of right targeted characters by the user.

Description

Ways to improve handwriting input efficiency

The present invention relates to a technique for handwriting input, and more particularly to a method for improving the efficiency of handwriting input.

According to the world language, it can be roughly divided into an alphabetic language and a graphic language. In terms of handwriting input, it includes a body control input and a touch input. Each word of the pinyin text is In the sequence of letters, the handwriting input is usually written according to the letters of the sequence. The input process may encounter confusion of the letter recognition. The input person needs to filter some candidate letters provided by the device to get the correct one. The word-based language (such as Chinese, Japanese, and Korean) has so-called strokes. In Chinese, there are different ways to define it. The basic strokes are simply classified into five types: horizontal, vertical, 撇, point, and fold. The strokes of each word are composed of the five most basic ones.

Chinese character input strokes have a certain order, which is called stroke order. Handwriting input is usually written according to the strokes of this sequence. The electronic device provides candidate words according to the sequence of possible strokes (usually containing the desired input). The target word) allows the user to select the desired word among the candidate words. However, there are many strokes in Chinese characters, and the handwriting input speed is slow, which affects the applicability of handwriting input. If it is too sloppy, it may make the electronic device unrecognizable. Therefore, how to increase the speed of handwriting input without affecting the recognition of the electronic device is At present, a topic to be solved by handwriting input technology. In view of the above, the present invention proposes a method for improving the efficiency of handwriting input in order to effectively overcome the above problems in view of the above-mentioned shortcomings of the prior art.

The main object of the present invention is to provide a method for improving the efficiency of handwriting input, which can find a candidate word from a Chinese character font by only a part of a stroke of a Chinese character, and arrange it on the touch screen according to the similarity.

Another object of the present invention is to provide a method for improving handwriting input efficiency, which defines a stroke order of a Chinese character as a stroke order coding sequence, and gives a basic glyph of each stroke a code as long as the user inputs a stroke of a Chinese character by handwriting. If there is a stroke order coding sequence in the Chinese character in the Chinese character font that matches the basic glyph coding sequence of the part of the stroke, it becomes a candidate word.

A further object of the present invention is to provide a method for improving handwriting input efficiency, which cuts Chinese characters into four squares, defines the position of each stroke of the Chinese character, and adds the position to the stroke order coding sequence to become a auxiliary sequence, Sort the similarity between the candidate word and the input target word.

To achieve the above object, the present invention provides a method for improving the efficiency of handwriting input, comprising the steps of: creating a Chinese character font, the Chinese character font comprising a stroke order coding sequence of a plurality of Chinese characters, each stroke order sequence corresponding to the order of strokes of a Chinese character, The stroke corresponds to a basic glyph code; a part of the stroke of the target word is input on a touch screen, and the part of the stroke can be a stroke with a discontinuous stroke, and a part of the stroke is converted into one of the basic glyph codes by using a processor. Sequence; comparing the subsequence with the stroke order coding sequence in the Chinese character font, determining whether there is a candidate word matching the subsequence in the stroke order coding sequence of the Chinese character; and displaying the candidate word on the touch screen.

Figure 1 is a flow chart of a method for improving handwriting input efficiency of the present invention.

Fig. 2 is a detailed flow chart of step S16 in Fig. 1.

The invention is a method for improving the efficiency of handwriting input, and according to the hand of each Chinese character The written stroke order and the stroke position define the stroke order coding sequence. The user only needs to hand-write some strokes of the Chinese character, that is, any sub-sequence, and the Chinese character containing the sub-sequence can be found from the Chinese character font and listed as a candidate word.

Please refer to FIG. 1 , which is a flowchart of a method for improving handwriting input efficiency according to the present invention. First, step S10 establishes a Chinese character font library, wherein the Chinese character font library includes a stroke order coding sequence of a plurality of Chinese characters, and each stroke order code sequence corresponds to a Chinese character stroke. The order, and the stroke corresponds to a basic glyph coding, and the basic glyph coding includes various basic glyphs of Chinese characters, and the coding table thereof is as follows:

The stroke order coding sequence includes one main sequence of only basic glyph coding and one auxiliary sequence including a basic glyph coding and a position of each stroke, and the "brother" is taken as an example, and the stroke includes , 1, 丿, 乚, corresponding to the number 2,6,1,3,10 in the code table, so the main sequence of "brother" is [2,6,1,3,10]. In addition to the auxiliary sequence, in order to additionally increase the discriminating degree of the handwritten stroke, roughly distinguish the position written by the stroke, assuming that each Chinese character is filled in a virtual font square, the virtual font square is divided into upper left, lower left, upper right, and lower right. Small squares of the same size (field shape, respectively called upper left, lower left, upper right, lower right; the long squares of the upper left and lower left are called the left side; the upper right and the lower right are called the right side; upper left; The upper right is called the upper part; the lower left and the lower right are called the lower part), and the square where the stroke is mainly located records its position. If more than three-quarters of the strokes are in the upper left, it is called The position of the stroke is the upper left; and so on, the same strokes can be defined in the upper right, lower left, and lower right. When a stroke passes through the upper left and lower left squares, it is less than three-quarters of the two squares, but more than three-quarters of the lengths are on the left, and the position is called The left side; the same reason can define the strokes on the right, above and below. Strokes that do not belong to these positions (must pass through at least three small squares) are called "medium". Therefore, the code of "brother" can be written as 2 upper left, 6 upper, 1 middle, 3 lower left, 10 lower right, and the clearer "brother" word stroke and code are as follows: Taking the word "country" as an example, the main sequence is [2,6,1,2,6,1,1,13,5,4,1], and the auxiliary sequence is [2 left, 6 in, 1 on, 2 left, 6 left, 1 left lower, 1 left lower, 13 right, 5 right upper, 4 middle, 1 lower], in addition, the "national" word stroke order and coding are as follows:

After all the stroke sequences of the Chinese characters have been stored in the Chinese character font, when the user wants to start the handwriting input, a target is input on a touch screen as described in step S12. Part of the stroke of the word, this part of the stroke can be a stroke with a discontinuous stroke. For example, if the target word is a Chinese character of eight strokes, the user can input only the first three strokes of the target word and the second to last stroke, for a total of four strokes; Next, in step S14, the partial stroke and the basic glyph coding table are compared with each other by a processor, and converted into a sub-sequence including the basic glyph coding. If the target word has a stroke order of a1a2a3a4a5a6a7a8, each of the letters ai represents a stroke. Encoding, the user handwriting input any subsequence of the stroke order of the target word, such as a1a3a4a7, a2a4a6a7a7a8 or a1a2a4a8, etc.; step S16 compares the subsequence with the stroke order coding sequence in the Chinese character library, and determines whether there is any stroke sequence of the Chinese character The candidate words conform to the sub-sequence, and all the candidate words are displayed on the touch screen in step S18 for the user to select.

The touch screen is electrically connected to the processor, such as a tablet, a touchpad, a touch-sensitive mobile phone, a touch screen connected to a computer, and the like.

Step S16 further includes two steps in comparing the subsequence and the Chinese character font. As shown in FIG. 2, firstly, the main sequence is compared as in step S162, that is, only the basic glyph encoding is compared, and all the stroke encoding sequences of the Chinese character library are aligned. Performing screening, picking out candidate words corresponding to the sub-sequences from each main sequence; then, in step S164, sorting the selected candidate words, comparing the similarity between the sub-sequences and the candidate words according to the auxiliary sequence, and finally sorting by similarity The candidate words are displayed on the touch screen as in step S18.

Taking the words "Liu", "Quiet" and "钧" as an example, Liu's abbreviation can be , static can be written The last 钧 can be written as The user does not need to write a complete word, and only writes part of the stroke according to the stroke order. The candidate word can also be found by the ratio of the stroke order coding sequence to the sub-sequence of the target word, and then the position of each stroke is used to determine which candidate word is used. The subsequence of the target word is most similar. All candidate words are displayed on the touch screen, but the most similar candidates are listed first.

The invention avoids the user's handwriting and is unrecognizable, and provides fault tolerance in position discrimination, so that the stroke weight corresponding to the handwritten position is the highest, the weight of the adjacent position is second, and the like. For example, the first stroke of the word "Liu" If the stroke written by the user is too long, it is judged as the left side, not the upper left, then the left or lower left stroke is " An appropriate score will be obtained to avoid the target word's weight being too low.

Furthermore, the present invention further includes a dictionary, which can be divided into a system dictionary and a user dictionary. The system dictionary combines a common dictionary and a special domain dictionary required by the typewriter, such as a biomedical dictionary; the user dictionary includes Single words, words, and commonly used text fragments, articles, or any symbolic material (such as a notation of a song) and how often it appears in a large amount of corpus. Therefore, the present invention can have a smart memory vocabulary function, and the input words, common strings, or vocabularies already stored in the dictionary can be input in a more simplified manner when the user inputs the next time, taking "Liu Jingwei" as an example. Assuming that "Liu Jingwei" has been entered or stored in a dictionary and is regarded as a vocabulary, the string Liu Jingyi can be searched with fewer strokes, such as Or even The processor sequentially compares the three target words to find possible candidate words.

In summary, the method for improving handwriting input efficiency of the present invention reduces strokes during handwriting input, and each Chinese character is arranged as a stroke order coding sequence according to its basic character shape, and the user only needs to manually input any of the stroke order coding sequences. The subsequence can predict the target word as one of the candidate words according to the Chinese character font. The longer the subsequence, the fewer candidate words containing the subsequence; and the similarity between the candidate word and the target word according to the position of the stroke According to the similarity and the frequency of use, the candidates with high similarity or frequently used can be ranked in front, so that the user can select, and the first stroke code of the subsequence does not have to be the first stroke of the word. Therefore, for the Chinese characters with complicated strokes, if the user forgets the correct writing of the words, but still remembers some of the strokes, the correct words can still be obtained by inputting these strokes, without switching other input methods, and speeding up the input speed. Entering simplified characters is faster.

The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Therefore, any changes or modifications of the features and spirits of the present invention should be included in the scope of the present invention.
