Abstract

According to the present invention, a system for implementing the English cursive script handwriting of a user involves taking, as an input, a predetermined number of handwritten letters directly written by the user, specifically in English cursive script, and automatically deducing and implementing the handwriting of the user through the inputted handwritten letters. The system of the present invention enables preceding letters and following letters to be naturally interconnected, while taking the characteristics of English cursive script, in which the letters are interconnected, into consideration.

Description

User English handwriting handwriting implementation system

The present invention is a user handwriting writing system implementation of the user, and more specifically, the user's handwriting, in particular, the English handwriting is input in accordance with the appropriate number of characters to automatically infer and implement the handwriting through this, but due to the characteristics of the English handwriting The present invention relates to an English handwriting handwriting implementation system that enables a link between a preceding character and a trailing character more naturally.

Conventionally, in order to recognize the handwriting, it is necessary to use an additional device such as an additional character input device or a scanner. However, the current touch screen technology has been rapidly developed so that a mobile communication terminal equipped with such a touch screen may be used without the additional device mentioned above. A function of allowing a user to immediately recognize a character written on a touch screen (this is called an OCR function) to find a meaning or to send a text message.

In an environment such as a touch screen as well as a computer to which a scanner is connected, a system that automatically inputs the user's handwriting by analyzing the user's handwriting in advance, beyond the OCR function of recognizing the character input by the user, is implemented first. It receives a certain number of handwritings and automatically generates a handwriting of the user through a computer program or other application, and is well-published in Korean Patent Nos.

Korean Patent No. 801224, 'User Handwriting Implementation System and Method,' which is the applicant's patent, classifies Korean phonemes into 19 consonant groups, vowel groups divided into 5 groups based on similar forms, and 1 support group for support. A phoneme classification module having a baseline setting unit for measuring a baseline according to the principle of Cheonjiin in the vowel group; A handwriting input module configured to receive at least 190 handwritings through a sample sentence; A bend measuring unit that grasps the bend state of a run in each phoneme or syllable of the handwriting, a point designation unit that designates a point at a bend point of the run R in the bend measuring unit, and a specific number when the run is a curve A shape determining module comprising a curvature measuring unit having curvature measuring means for designating only points of the curve and curve substitution means for determining and determining whether the curve determined by the curvature measuring means corresponds to a predetermined arc shape of a circle; A distance determining module for measuring a vertical to horizontal distance between the top, bottom, left and right outermost points of two phonemes and syllables; A positioning module for determining positions of the top, bottom, left and right outermost points of two phonemes to syllables; A handwriting combination module for combining various handwriting on the basis of the data determined by the shape determining module, the distance determining module and the positioning module; And an output module for outputting the handwriting combined by the handwriting combination module.

Although the above technique is particularly useful in the case where each syllable is separated from each other, such as Korean, it is recognized that the advantage can be utilized. However, when letters are interconnected, such as English handwriting, that is, in English handwriting, Although the handwriting may not be a problem to implement, there is a problem that it is difficult to apply the technique as it is when connecting each character naturally.

1 is an exemplary view showing an example of implementing the English handwriting using the prior art.

Patent No. 801224 has a configuration called a curvature determining section, which has a function of determining the curvature (curvature, inflection point) of the curve constituting the phoneme / syllable and substituting a curve suitable for the curvature.

However, according to the above technique, when a user inputs one individual character corresponding to English handwriting and recognizes the handwriting, and then tries to connect the preceding / following character by English handwriting technique, the end of the preceding character and the beginning of the trailing character Since the parts are unconditionally connected with a curve having a specific curvature, there is a problem that the connection state of each letter is quite unnatural as shown in FIG. 1.

This is because, in English handwritten characters, especially the end of the letter is extended or extended upward in the upward direction, as described above, the English handwritten text is more specific than using the end of the letter as it is. By arranging this part by cutting the rule and connecting it naturally with the subsequent character, a more natural and awkward English handwriting may be realized.

Therefore, when implementing English handwriting in a user's handwriting, each English handwriting character is input from the user individually, but the end point of the preceding character is naturally cut in consideration of the leading / trailing relationship and the connection between the characters. Then, it is necessary to develop a new and advanced system that enables the user's English handwriting to be more natural by connecting with trailing characters.

SUMMARY OF THE INVENTION The present invention has been made to overcome the problems of the above technique. In particular, in a system for recognizing and implementing user handwriting for English handwritten characters, the end of the preceding character is raised upward when two or more characters are consecutive. The main object of the present invention is to provide a user English handwriting implementation system that enables the user to easily recognize individual letters of the alphabet by connecting with trailing characters in a natural state, and then implement a natural combination state with trailing characters.

Another object of the present invention is to provide a basis for recognizing the handwriting of the user in a simpler manner by using a mobile communication terminal having a touch screen when receiving the handwriting from the user.

Still another object of the present invention is to cut the upper end of the preceding character in a rational and scientific manner when the preceding character and the trailing character are continuous, and then naturally connect the trailing character.

In order to achieve the above object, the user English handwriting handwriting implementation system according to the present invention, receives the English handwriting characters from the user through the character input means to determine the distance and position between adjacent characters and according to the bend of the run (run) Starting point for identifying the start point and end point position of the English handwritten characters input by the user through the character input means in a state including a handwriting recognition module for recognizing the handwriting of the user by grasping the shape of the character by specifying the point Recognition module; A connection determination module for determining whether there is a special symbol or a space between a preceding character and a trailing character when two or more English handwritten characters are consecutive; A cutting point designation module for designating a point located around an end point of the English handwritten character of the user identified by the handwriting recognition module as a cutting point; The truncation module for truncating and deleting a run from the truncation point to the end point of the preceding character when it is determined that there is no special symbol and a space between the preceding character and the trailing character in the connection determination module; Character connection module for connecting the line segment from the cutting point of the preceding character to the start point of the trailing character;

The cutting point designation module may include an end point proximity point designation unit that designates a point closest to the end point as a cutting point among a plurality of points constituting an English cursive character.

In addition, the cutting point designation module, characterized in that it further comprises a flat point designation for designating a point closest to the end point of the point among the points included in the English handwritten characters as the cutting point.

In addition, the connection module, characterized in that it comprises a; curved connecting portion for connecting both characters in a curve having a curvature corresponding to the curvature of the curved run extending from the portion before the cutting point of the preceding character.

According to the user English handwriting handwriting implementation system according to the present invention,

1) Recognize your handwriting for each alphabet handwriting, and then connect each letter more naturally and smoothly without any awkwardness when the alphabet is combined with another alphabet,

2) Convenience can be increased by receiving handwriting from the user through the generalized touch screen.

3) Naturally and systematically cut a part of the end of the preceding character, and then connect the trailing character with a straight line or a curved line to realize more realistic and realistic English handwriting.

The present invention receives the English handwritten characters from the user through the character input means to determine the distance and position between the adjacent characters and to identify the shape of the character in the manner of specifying the point according to the run state (run) of the handwriting In the state including a handwriting recognition module for recognizing, the starting point recognition module for identifying the starting point and the end point position of the English handwritten characters input by the user through the character input means; A connection determination module for determining whether there is a special symbol or a space between a preceding character and a trailing character when two or more English handwritten characters are consecutive; A cutting point designation module for designating a point located around an end point of the English handwritten character of the user identified by the handwriting recognition module as a cutting point; The truncation module for truncating and deleting a run from the truncation point to the end point of the preceding character when it is determined that there is no special symbol and a space between the preceding character and the trailing character in the connection determination module; Character connection module for connecting the line segment from the cutting point of the preceding character to the start point of the trailing character; consisting of the best form for the practice of the invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numerals in each of the drawings refer to like elements.

First of all, the system according to the present invention receives a user's handwriting, as described in Patent No. 801224, and the distance of a phoneme / syllable (in English handwriting, it is referred to as a letter because there is no concept of phoneme). It is based on the recognition of the position, shape, etc. first and then the combination of various forms of handwriting. In other words, the handwriting combination module, which is a component provided in Patent No. 801224, is specialized, and the user's handwriting is analyzed and recognized at the system level based on the user's handwriting on the recognized individual English handwriting. Its main feature is to provide a system that allows these characters to be connected more naturally.

In addition, a means for receiving a user's text may be a device known in the art, such as a character recognizer, a scanner, but in response to the modern technology that has developed a touch screen, a touch monitor, a touch mobile terminal, a game device, a PMP / It would be desirable to have a touch screen mounted on a MID / tablet PC or the like.

Figure 2 is a block diagram showing the configuration of a user English handwriting handwriting implementation system according to the present invention.

As described above, the system according to the present invention is a differentiation and development of the handwriting combination module, which is particularly distinguished from the components disclosed in Korean Patent No. 801224, specifically, the handwriting recognition module 110 and the starting point recognition module. 120, a connection determination module 130, a cutting point designation module 140, a cutting module 150, and a character connection module 170 are included.

The handwriting recognition module 110 provides the user with the number of characters that can grasp the appropriate number of phonemes to receive the user's handwriting through a character input means (a touch screen as described above is most preferred), and then specifies a point to run. In order to understand the flow of a run, a function of recognizing distance, shape, and position of a character is performed, which is not necessarily the same as that of Patent No. 801224, but a handwriting input module, a shape determining module, a positioning module, and a distance of Patent No. 801224. Since the basic function of the decision module can be sufficiently predicted and easily implemented at a level of ordinary skill in the art, more detailed and detailed description will be omitted.

The starting point recognition module 120 is to recognize the starting point (始終點) of the character, that is, the starting point and end point through the character input means, that is, to write a character when the user inputs the character through the character input means The position where pressure is first applied to the character input means is called a starting point, and when the character writing is finished, the position belonging to the last part is called an end point, thereby providing a function of recognizing the starting point and ending point.

Currently known character input means, preferably a touch screen is largely divided into a capacitive and a pressure-sensitive type, both of which can easily identify the location to which the electric or pressure is applied, the starting point recognition module 120 according to the present invention is a specific touch screen Regardless of the method, the basic functions of the touch screen give the user the ability to identify the starting and ending points for writing individual characters.

In order to implement a specific sentence or word, the connection determination module 130 determines whether each character is continuously connected in the input contents when a user inputs a plurality of characters or words, or a dot (.), A comma ( Provides a function to determine whether special symbols or blanks (generally blanks between words) are located, such as,), hyphen (-), and at (at) (@).

For example, d, o, g can be used consecutively to implement a three-letter word like dog, but when implementing the email address "abc@gmail.com", the special symbol @ is placed between c and g. and a special symbol dot (.) is positioned between l and c. The connection determination module 130 determines whether the special symbol and the space are located between the characters in the process of inputting individual characters continuously. Grants the ability to

This is to give a premise function for determining whether to cut a run from the end point of the construction preceding character to be described later to the cutting point. In other words, if the character is continuous to form a specific word, the preceding character Truncation of the run from the end of to the truncation point must be truncated, but if a special symbol or blank is placed between each character, it is rather unnatural to cut the run from the end of the preceding character to the truncation point. Because.

The cutting point designation module 140 according to the present invention is provided on the run side of a portion around the end point of a preceding character (referred to as a preceding character) of two consecutive character relations in a plurality of characters provided to implement the handwriting. Provides the ability to specify a so-called cutting point.

3 is an exemplary view showing a cutting point designated by the cutting point designation module of the present invention.

The cutting point means that when the end of the preceding character is unnecessarily raised upward in English handwriting, it becomes very difficult or unnatural to connect with the trailing character. Since a large number of character combinations of 26 * 26 = 676 from a to z must be input, the handwriting recognition module 110 provides a state in which individual characters can be implemented, and then the connection state is more natural when interconnecting each individual character. To cut off a portion of the leading character.

Referring to FIG. 3, a cut point (in FIG. 3, circled) on one side of a run (the length of a continuous pixel) corresponding to a preceding portion of an end point (indicated by a square in FIG. 3) in the English cursive a Display) is specified.

The cutting point designation module 140 for designating such a cutting point provides a function of designating a portion around the end point of the character as the cutting point.

The cutting point designation module 140 uses the technology of designating the corresponding point where the variation occurs as a point when the position of the variation occurs in the bending specific portion described in Patent No. 801224, that is, the concept of a point occurring in a run. To provide a basis for specifying cut points.

Hereinafter, various specific embodiments of the cutting point designation module 140 will be described.

The first embodiment of the cutting point designation module 140 includes an end point proximity point designation unit 141, which is closest to the end point of the character among the plurality of points included in the run forming the English handwritten character. Provides the ability to designate points as cutting points.

This end point proximity point designation unit 141 is inevitably used in order to connect the trailing character in the outer upward direction (all alphabets. Since the tip is naturally drawn in the upward direction, the focus is on the characteristic that the tip is not bent or the curvature does not change.

That is, the English cursive character has a characteristic that the end portion of the curvature rises in the form of a curve when connected in the upward direction in order to be connected to the trailing character. When the starting point has a principle of designating a point as a cutting point for the point at which the curvature changes.

The second embodiment of the cutting point designation module 140 has a flat point designation portion 142, and the flat point designation portion 142 is the derivative value F '(x) of the curve for the end of the character. A function of designating a point where 0 (tilt 0), that is, a point closest to the end point among parallel points, as a cutting point.

That is, in English cursive, it is inevitable that there is a part that continues in the downward direction before the end part rises in the upward direction, so that the point where the downward direction begins to rise in the upward direction, that is, the derivative value F '(x) = 0 The principle is to specify the cutting point.

The flat point designator 142 has a meaning of setting the flat point as a cutting point in advance because the flat point whose slope is zero is expected to extend in a curved shape in the upward direction.

Cutting module 150 according to the present invention from the cutting point designation module 130 to the cutting point specified by the cutting point designation module when it is determined that there is no special symbol or blank between the two consecutive characters in the connection determination module 130 It provides the function to cut and delete the run.

In other words, the cutting module 150 is to prevent the problem that the end portion is extended or stretched upward more than necessary in English handwritten characters to prevent a problem that does not ensure a natural connection state with the subsequent characters, the end point at the cutting point It is responsible for deleting the end of the English cursive writing to ensure a more natural connection with subsequent characters.

Figure 4 is an exemplary view showing a state in which adjacent characters are connected by the character connection module of the present invention.

The character connection module 160 according to the present invention serves to connect the cutting point of the preceding character whose end portion is cut and the starting point of the trailing character, wherein the following line has a straight form as shown in FIG. 4. It may be said to be the most intuitive and clear method, but is not limited thereto, and additionally includes a curved connector 161 to correspond to the curvature of the curved run that extends from the portion before the cut point of the preceding character. Of course, it is also possible to connect both letters in a curve with curves.

According to the system according to the present invention having such a configuration, in particular, a system that implements an English handwriting of a user provides a characteristic that can show a natural connection state to prevent awkward as much as possible between the leading and trailing characters.

As described so far, the configuration and operation of the user English handwriting handwriting implementation system according to the present invention have been represented in the above description and the drawings, but this is merely an example, and the spirit of the present invention is not limited to the above description and the drawings. Various changes and modifications are possible without departing from the technical spirit of the present invention.

The present invention will be sufficient for industrial application because it can be installed in a computer or mobile phone in the form of an application or a separate program and can be produced in large quantities.
