The management unit 130 may be provided with an analysis unit 135 that analyzes the handwriting information 11 .

The analysis unit 135 may extract a handwriting image included in the handwriting information 11 .

The analysis unit 135 may search for a guide image matching the text image and analyze the matching accuracy between the searched guide image and the text image.

8 is a schematic diagram illustrating an operation of analyzing matching accuracy.

The analysis unit may generate one text image corresponding to one letter or one cell in which one guide image is formed. So-called, when writing letters in each of the square cells formed on the grid paper, the entire cell of the grid paper on which the letters are written may be the analysis target of the analysis unit. In other words, the text image ('student text' in FIG. 8) and the guide image ('textbook text' in FIG. 8 ) may be formed within a closed curve (rectangle in FIG. 8 ) having the same size and shape.

In this case, the analysis unit may divide the inside of each closed curve filled with one letter into a plurality of area cells (each area surrounded by dotted lines in FIG. 8 ).

A first black-and-white ratio of each region column with respect to the guide image may be defined, and a second black-and-white ratio of each region column with respect to the text image may be defined. For example, in the area where a part of the slanted mark on the right side of the vowel 'a' is displayed among the letters 'A' in FIG. 8, the first black-and-white ratio of the textbook text may be 20%, and the second black-and-white ratio of the student's text may be 80%. .

The black-and-white ratio can represent the ratio of 'black' to the total area of the area cell when the area occupied by text in each area cell is defined as 'black' and the empty area area is defined as "white" in each area cell. have. Alternatively, it may be defined as an area of 'black' with respect to an area of 'white'.

The analyzer may analyze the matching accuracy corresponding to whether the handwriting image matches the guide image by using the difference between the first black and white ratio and the second black and white ratio.

The analysis unit may compare a preset step-by-step setting ratio and matching accuracy. According to the comparison result, the analysis unit may display the degree (level) of matching of the handwriting image with the guide image, such as 'very good', 'good', 'normal', 'poor', 'very poor', and the like.

The analysis unit may analyze a difference between the first black-and-white ratio and the second black-and-white ratio for every area cell included in one closed curve, and analyze the matching accuracy of the corresponding text according to the analysis result.

Returning again to FIG. 2 , the analysis unit 135 may provide feedback information including matching accuracy to the first terminal 10 through the first communication unit 110 .

According to the present embodiment, the user can practice writing using various contents that he or she desires without having to follow the contents provided by the server 100 .

Specifically, according to this embodiment, the server 100 does not need to discuss the contents of the user's handwriting information 11 with the user in advance.

For example, when the user writes 'today's handwriting practice' by using the collector 90 , the corresponding handwriting information 11 may be obtained from the server 100 . In this case, the server 100 may be in a state of not knowing whether the handwriting information 11 is the content of 'today's handwriting practice'.

In order to analyze the user's handwriting 'today's handwriting practice', the server 100 may extract each letter (handwriting image) included in the 'today's handwriting practice'. The server 100 may search for a guide image matching the extracted characters from the database. The guide image may correspond to a model text that the user should follow. The server 100 may analyze the matching degree between the searched guide image and the text image and provide it to the user.

According to the management unit 130 of the present invention having the above configuration, the user can perform corrective practice in a free environment in which arbitrary contents can be taken.

Some appointment environments may be required to take notes of the contents promised in advance. In the case of the appointment environment, the server 100 does not need to search for a guide image matching the text written by the user. Because you already know.

For example, in the initial stage of handwriting correction, handwriting practice may be performed while following the guide image displayed on the digital textbook 91 as it is. In this case, the user may practice writing in an appointment environment for taking notes according to the contents provided by the digital textbook 91 . In this case, the guide image displayed on the digital teaching material 91 may be provided to the digital teaching material 91 through the server 100 and the first terminal 10 in order. Even when the user enters the stage of writing in the blank space due to the user's mastery, if an appointment environment is required for easy matching between the handwriting information 11 and the guide image, the interest in writing practice is reduced due to the limitation of the degree of freedom. can be significantly reduced.

According to the present embodiment, a free environment can be provided through a configuration for extracting a handwriting image from the user's handwriting information 11 and a configuration for searching a guide image matching the text image.

Meanwhile, the size of the handwriting image extracted from the handwriting information 11 may vary greatly. Therefore, the text image may have a different size from the guide image, and it is unreasonable to analyze the matching degree in a state where the sizes are different.

The analysis unit 135 may enlarge or reduce at least one of the text image and the guide image so that the text image and the guide image have the same size. When the size of the handwriting image and the guide image are the same, the analysis unit 135 may analyze the degree of matching between the two and provide the analysis result to the first terminal 10 .

Meanwhile, the analysis unit 135 may generate a duplicate image in which a guide image having the same size and a text image are overlapped. In this case, the first communication unit 110 may transmit the duplicate image to the first terminal 10 .

The user can view the duplicate image through the first terminal 10 and intuitively grasp the difference between his or her own handwriting and the guide image.

In order to help correct handwriting by checking the duplicate image, it is good to visually distinguish the guide image and the handwriting image included in the duplicate image.

The analysis unit 135 may manipulate at least one of the guide image and the text image so that the guide image and the text image can be distinguished in the state of the overlapping image. In this case, the manipulation may be to transform the original guide image or the original text image. The transformation of the original may be performed on at least one of outline thickness, outline type, text color, and transparency.

The matching degree may indicate how similar the text image is to the guide image. In this case, the matching degree information may be subdivided in order to provide the user with additional information on handwriting correction.

In order to provide detailed matching degree information, the analysis unit 135 may recognize the overall size and partial size of the text image. The total size may indicate the length, width, and area of the entire text, or may include the area of a virtual closed curve inscribed in the outline of the text. The portion size may include a size (length, width, area) of a vowel included in one letter, a size of a consonant (at least one of length, width, and area), an interval between a consonant and a vowel, and the like.

The analysis unit 135 may extract a guide image, which is a comparison target of the handwriting image included in the handwriting information 11 , from the database.

The analysis unit 135 may change the text image or the guide image so that the entire size of the guide image is matched, or the text image or the guide image so that the size of a part of the guide image is matched to a specific part.

The analysis unit 135 may compare the handwriting image and the guide image in a state where the change of the handwriting image or the guide image is completed. Specifically, the analysis unit 135 may set the area of the guide image to a plurality of sizes, and measure at least one of an unreached range, an appropriate range, and an excess range of the text image by using the plurality of sizes.

3 is a schematic diagram illustrating an operation of the analysis unit 135 .

The analyzer 135 may operate in a first mode, a second mode, and a third mode.

The first mode may be a mode for measuring the primary area of the guide image and the range of the text image.

The second mode may be a mode for measuring the secondary area of the guide image and the range of the text image.

The third mode may be a mode for measuring the tertiary area of the guide image and the range of the text image.

The secondary region may have a size including the primary region, and the tertiary region may have a size including the secondary region.

As shown in FIG. 3 , the primary region may indicate an unreached range of the guide image. The primary region may represent the guide image itself after the resizing step is completed.

The first mode may be used to measure whether the handwriting information 11 does not reach the size of the consonants and vowels of the guide image. The measurement result of the first area may be used to identify characters that the user writes with shorter strokes or thinner than the recommended ones.

The secondary region may indicate an appropriate range of the guide image. When strokes of a character written by a user are included in the secondary area, it may be analyzed that the user's handwriting information 11 matches the guide image.

The tertiary region may represent an excess range of the guide image. The tertiary region may define a so-called boundary that should not be crossed. From the moment the second region is exceeded, the analysis unit 135 may analyze that the user writes a stroke of the corresponding character longer or thicker than recommended. When the excess exceeds the tertiary region, the analysis unit 135 may set a tag to be distinguished from other parts in the corresponding part. The corresponding tag may be used to graphically display prominently to the user. In addition, the corresponding tag may act as a factor that significantly lowers the degree of matching.

According to the present embodiment, it can be seen that the tertiary region has the largest size, the primary region has the smallest size, and the secondary region has a center size. At this time, it is reminded that the first area, the second area, and the third area are different concepts from general enlargement or reduction.

Abuse or reduction changes not only the length and width of the strokes forming the letter, but also the spacing between the centers of the strokes compared to the original, and the position of the centers of the strokes as well. The primary region, secondary region, and tertiary region are somewhat similar to zoom in that the length and width of the stroke are increased or decreased. However, in the first region, the secondary region, and the tertiary region, the distance between the centers of the strokes may be kept constant. In addition, the central position of the stroke may also be fixed in one place.

As a result, although the primary region, the secondary region, and the tertiary region have large and small relationships, they may be superimposed on each other.

4 is a schematic diagram illustrating the second terminal 20 on which correction information is displayed.

The handwriting information 11 uploaded to the server 100 by the first terminal 10 may be provided to the second terminal 20 of the proofreader by the user's request or the server 100 .

The proofreader may check the handwriting information 11 displayed through the second terminal 20 and add correction information on the handwriting information 11 by using a calibration pen 29 such as a stylus pen. The handwriting information 11 to which the correction information is added becomes feedback information and may be transmitted to the server 100 by the second terminal 20 . Feedback information including correction information may be transmitted to the first terminal 10 by the server 100 .

Meanwhile, the analysis unit 135 may analyze the feedback information in order to improve the learning effect through correction.

The feedback information may include the handwriting of the proofreader. The corresponding handwriting may be added during the correction process for the handwriting information 11 .

The analysis unit 135 may compare the handwriting of the user included in the handwriting information 11 with the handwriting of the proofreader included in the feedback information, and generate feedback information including the result of the handwriting comparison. The feedback information of the analysis unit 135 may be provided to the first terminal 10 through the first communication unit 110 . According to the present embodiment, the user of the first terminal 10 may have an opportunity to compare his or her handwriting with the handwriting of the proofreader.

The analysis unit 135 of the server 100 may extract a handwriting image included in the collected handwriting information 11 and search for a pre-stored guide image (collection step S610).

The analysis unit 135 may recognize the overall size and the partial size of the text image (recognition step S620). If necessary, the analysis unit 135 may reduce/enlarge the text image or the guide image so that the overall size of the text image matches the overall size of the guide image. Alternatively, the analysis unit 135 may reduce/enlarge the text image or the guide image so that the size (partial size) of one of a specific stroke, consonant, and vowel included in the text matches the partial size of the guide image ratio.

The analysis unit 135 may compare the guide image and the text image (comparison step S630).

In this case, the comparison step S639 may include a first mode (S631), a second mode (S632), and a third mode (S633).

In the first mode ( S631 ), the analyzer 135 may measure the primary area of the guide image and the range of the text image.
