Figure 2 is a block diagram showing a handwriting correction device of the present invention. The handwriting correction apparatus of FIG. 2 may represent the server 100.

The server 100 may be provided with a first communication unit 110, a management unit 130, and a second communication unit 120.

The first communication unit 110 may communicate with the user's first terminal 10 and receive the user's handwriting information 11. The first communication unit 110 may transmit feedback information to the first terminal 10.

The management unit 130 may manage the handwriting information 11.

For example, the menu unit 133 may provide the first terminal 10 with correction time information necessary for mastery of each font along with a selection menu. The user who checks the correction time information can select the type of font in consideration of his or her study period.

An analysis unit 135 for analyzing the handwriting information 11 may be provided in the management unit 130.

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

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

8 is a schematic diagram showing 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. When writing a letter for each square formed on a so-called grid paper, the entire cell of the grid paper on which the letter is written can be the subject of analysis by 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 in 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 a dotted line in FIG. 8 ).

A first black and white ratio of each area cell with respect to the guide image may be defined, and a second black and white ratio of each area cell with respect to the text image may be defined. As an example of an area cell in which a part of the right beep mark of the vowel'ㅏ' 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 text may be 80%. .

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

The analysis unit may analyze a matching accuracy corresponding to whether the text image matches the guide image by using a 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 of correspondence (level) of the text image with respect to the guide image such as'very good','good','normal','shortage','very insufficient', 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 all areas included in one closed curve, and analyze the matching accuracy of the corresponding text according to the analysis result.

Returning 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 may perform writing practice using various contents desired by the user without having to follow the contents provided by the server 100.

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

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

In order to analyze the user's handwriting'today's writing practice', the server 100 may extract each character (text image) included in the'today's writing practice'. The server 100 may search a guide image matching the extracted characters from the database. The guide image may correspond to exemplary 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, a user can perform calibration practice in a free environment in which arbitrary content can be written.

You may need a part of an appointment environment where you can take notes on the promised contents in advance. In the case of an appointment environment, the server 100 does not need to search for a guide image matching the text written by the user. Because I 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 can practice writing in an appointment environment in which the user takes notes according to the contents provided in the digital textbook 91. In this case, the guide image displayed on the digital textbook 91 may be provided as the digital textbook 91 through the server 100 and the first terminal 10 in order. Even if 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, there is an interest in writing practice due to the limitation of the degree of freedom. It can be greatly reduced.

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

On the other hand, the size of the text image extracted from the handwriting information 11 may vary greatly. Therefore, the text image may have different sizes from the guide image, and it is unreasonable to analyze the matching degree in different sizes.

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 sizes of the text image and the guide image become 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 the guide image having the same size and the text image overlap. In this case, the first communication unit 110 may transmit the duplicate image to the first terminal 10.

The user can see the duplicate image through the first terminal 10 and intuitively grasp the difference between his own writing and the guide image.

In order to help correct handwriting by checking the duplicate images, it is better to visually distinguish the guide image and the text 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 duplicate image. The manipulation at this time may be to transform the original guide image or the original text image. The transformation of the original may be performed with respect to at least one of an outline thickness, an outline type, a text color, and a transparency.

The matching degree can indicate how similar the text image is to the guide image. At this time, the matching degree information may be subdivided to provide additional information on handwriting correction to the user.

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

The analysis unit 135 may extract, from the database, a guide image to be compared with the text images included in the handwriting information 11.

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 change the text image or the guide image so that the partial size of the guide image is matched.

The analysis unit 135 may compare the text image and the guide image in a state in which the text image or the guide image has been changed. 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 unreachable range, an appropriate range, and an excess range of the text image by using the plurality of sizes.

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

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

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

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

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

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

As shown in FIG. 3, the primary region may represent a range of the guide image not reached. The primary area 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 a consonant or vowel of a guide image. The measurement result of the primary area can be used to identify characters that the user writes shorter or thinner than the recommendation.

The secondary area may represent an appropriate range of the guide image. When the strokes of the characters written by the 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 area may be what defines the so-called boundaries that should not be crossed. From the moment when the second area is exceeded, the analysis unit 135 may analyze that the user writes a stroke of the corresponding character longer or thicker than the recommended recommendation. When the excess amount exceeds the third area, the analysis unit 135 may set a tag that is distinguished from other parts in the corresponding part. The tag can be used to graphically display prominently to the user. In addition, the tag can act as a factor that significantly lowers the degree of matching.

According to this embodiment, it can be seen that the tertiary region is the largest, the primary region is the smallest, 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 from general expansion or reduction.

Abuse or reduction changes not only the length and width of the strokes forming the letters, but also the spacing between the centers of the strokes compared to the original, and the center position of the strokes. The primary, secondary, and tertiary areas are somewhat similar to zooming in that the length and width of a stroke increase or decrease. However, the first region, the second region, and the third region may have a constant spacing between the centers of the strokes. In addition, the center position of the stroke may also be fixed in one place.

As a result, although the primary region, the secondary region, and the third region have a large and small relationship, they can be superimposed on each other.

4 is a schematic diagram showing a 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 a user's request or the server 100.

The proofreader can check the handwriting information 11 displayed through the second terminal 20 and add correction information on the handwriting information 11 using a correction pen 29 such as a stylus pen. The handwriting information 11 to which correction information has been 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 proofreader's handwriting. The handwriting may be added in the process of correcting the handwriting information 11.

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

The server 100 may collect the user's handwriting information 11 in real time through the first communication unit 110 (S510).

The server 100 may analyze the matching accuracy between the text image included in the handwriting information 11 and the previously stored guide image through the analysis unit 135 of the management unit 130 (S520 ). Matching accuracy can be quantified in units of frequency, for example, in percent (%).

The analysis unit 135 may additionally analyze information on at least one of time required per character image, daily practice time, weekly practice time, and monthly practice time (S530).

The server 100 may transmit the analyzed matching accuracy and the time information to the first terminal 10 through the first communication unit 110 (S540).

6 is a flow chart showing another handwriting correction method of the present invention. The handwriting correction method of FIG. 6 may also be performed by the server 100.

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

The analysis unit 135 may recognize the total 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 entire size of the text image and the total size of the guide image coincide. 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 size of the guide image.

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

In this case, the comparison step S 639 may include a first mode (S 631 ), a second mode (S 632 ), and a third mode (S 633).

In the first mode (S 631 ), the analysis unit 135 may measure the primary area of the guide image and the range of the text image.
