Abstract
The present invention relates to a method for conveniently inputting Hangul characters in a portable electronic device such as a smart phone or an electronic device for a disabled person. The user can input Hangul by touching the desired consonant area of the keyboard made only of consonants and then dragging it in the shape of a vowel without touching off.
Description
The present invention relates to a method for conveniently inputting Hangul characters in a portable electronic device such as a smart phone or an electronic device for a disabled person.
There are various methods of inputting characters, especially Hangul, in a portable electronic device having a touch panel such as a smart phone. Keyboards in the qwerty array used in the iPhone® are often used, or a long-form Hangul input method often called "heaven-in-the-one" is used.
However, in the case of the qwerty array, since the size of a button in a small smartphone is too small, it is difficult to distinguish one button from the other by a finger. Also, in the case of the "Heavenly People" method, the input speed is not faster than expected.
Therefore, there is a need for an alternative that allows many people to input Hangul conveniently and quickly.
There are a number of prior art related to the Hangeul character input method. In recent years, an optical character recognition (OCR) method, in which a user recognizes a drag screen as a character as if it is written on a touch panel, is used.
However, when OCR is applied as it is, the number of strokes is larger than other languages such as English and Japanese. It is reported that the recognition rate is not high in Hangul which has its own initial, neutral, and longitudinal rules. It takes considerable time and the reaction time is slow. Accordingly, when all characters are recognized as OCR, the computation time of the electronic device is increased, which not only consumes the battery but also slows down the input speed compared with the above-described qwerty method or the overtone method.
Therefore, an attempt has also been made to integrate the OCR system with a keyboard.
As a representative example, Korean Unexamined Patent Publication No. 2000-0008540 proposes a method of arranging consonant keyboards on a touch panel to increase the size of the buttons and analyzing the drag using the touch panel to provide a collection.
However, in the conventional art, regardless of the position of the specific consonant input, the position of the finger or the input tool is moved over the center of the keyboard to newly touch and write the vowel. In the proposed method, the vowel is dragged without touching the keyboard after touching the consonant to write the vowel, whereas the prior art has a disadvantage of the time required to perform another touch and drag. For example, in the case of "ㅞ" or "ㅙ" having complex strokes, it is difficult to distinguish "ㅠ" from the case of inputting the vowel "ㅟ" There is a problem that it is lowered.
On the other hand, even in the case of a disabled person whose body is inconvenient and difficult to touch and release several times, there is a problem that the same method as the above-mentioned conventional technique is difficult to use.

Korea Patent Publication No. 2010-0114190
Korea Patent Publication No. 2012-0131480
Korean Patent Publication No. 2014-0083485
Accordingly, the present invention has been made in order to overcome the problems of the above-described conventional techniques.
Specifically, we propose a Hangul character input method capable of prompt input while providing only consonants so that the size of the key board button is large.
In addition, the problem of delayed response time, excessive computation time, and slow input speed problems that occur when the OCR method is applied to the existing Hangul is solved.
From the viewpoint of users, we propose a method of inputting Korean characters using features unique to Hangul that can be input in an intuitive and convenient way.
In addition, we propose a Hangeul character input method which can be conveniently applied to electronic devices specially designed for the handicapped.
In order to solve the above-mentioned problem, a user touches a desired consonant area of a keyboard made only of consonants, and then drags the touch panel in a shape of a vowel without touching, i.e., starts touching from a consonant, We propose a method of inputting Korean characters that can input Korean characters by moving a finger on the Korean character.
More specifically, the present invention provides a method for inputting Hangul characters in a portable electronic device including an operation unit and a touch panel or an electronic device for a disabled person, comprising the steps of: (a) detecting a touch of a consonant region of a touch panel; (b) outputting consonants corresponding to the detected consonant region to the input window; (c) detecting a drag trajectory from the touch detection time to the touch release time; (d) calculating by the arithmetic unit a vowel corresponding to the drag trajectory; And (e) the calculating unit outputs the calculated vowel in combination with the consonant output in the step (b).
The step (c) may further include: (c1) when the touch release is detected without the drag trajectory, the operation unit waits for the next touch detection; (c2) detecting an operation unit touch; (c3) determining whether the area of the touch detected in step (c2) is a consonant area; (c4) determining whether the consonant corresponding to the region of the touch detected in the step (c3) is a consonant region, combining the corresponding consonant with the consonant output in the step (b), thereby configuring a double consonant; And (c5) when the twin consonant configuration is possible in the step (c4), the operation unit outputs the twin consonants.
In the step (c), the arithmetic operation unit detects the drag trajectory from the touch detection to the touch release in the step (c2) after the step (c5), and the step (d) The method comprising the steps of:
In the step (c), if the twin consonant configuration is impossible in the step (c4) after the step (c4), the arithmetic part outputs a consonant corresponding to the consonant area in the step (c4) step; And (c61) the arithmetic unit detects the drag trajectory from the touch detection to the touch release in the step (c2), and the step (d) may be further performed.
In the step (c), if the area of the touch detected in the step (c3) after the step (c3) is not the consonant area, The method may further include a step of detecting the drag trajectory until the touch is released and proceeding to step (d).
The step (d) may further include: (d1) when the arithmetic unit can not calculate a vowel corresponding to the drag trajectory, the arithmetic unit ignores the drag trajectory and waits for the next touch detection.
On the other hand, in the case of the vowel operation, when the moving angle X in the rightward direction of the drag trajectory with respect to the horizontal axis is before or after the predetermined first angle P (-P <X <P) (-Q < Y < Q) is recognized as "l ", and the arithmetic operation is performed on the basis of the arithmetic operation And a step of calculating a vowel by comparing the order and combination of " - "and "?" Included in the drag trajectory with a sequence and combination stored in advance in the database.
It is possible to perform an operation by comparing the order and the combination with reference to FIG. 9 to be described below.
Characteristically, it is desirable to calculate "ㅣ" in the upward direction and to "ㅣ" in the upward direction after recognizing the word "ㅓ" in the upward direction if the touch is released.
Also, it is desirable to calculate "ㅣ" or "ㅣ" in left-downward or leftward direction and then to "ㅣ" in rightward-upward direction. Here, if it is recognized as "ㅡ" or "ㅣ" in the left-downward or leftward direction and then recognized as "ㅣ" in the upward direction, the height of the last recognition point "B" If the value (d) obtained by subtracting the height (A) is larger than a predetermined value, the operation is performed with the vowel "ㅟ", otherwise, the operation is performed with "ㅠ".
In the case of using the Hangeul character input method according to the present invention, the input speed can be greatly increased since characters can be input by dragging only after inputting the Hangeul character in the user's position, and unlike the OCR method, It is convenient to see the response of the input window immediately.
Furthermore, since the vowel is recognized as one drag after consonant input, the accuracy is greatly increased, unlike the above-described prior art patents.
In addition, unlike the OCR method, it is possible to identify the character only by a simple comparison with the existing database, thus consuming less battery.
Also, it is possible to provide a convenient input method not only for portable electronic devices but also for disabled persons whose body is inconvenient and difficult to touch and release many times.

In the present invention, the term "portable electronic device" means an electronic device that is small in size and portable and can input and output information through a touch through a relatively small display unit. For example, smartphones, PDAs, tablets, and the like may be included.
In the present invention, "electronic device for the disabled" is an electronic device specially manufactured for a disabled person, and similarly refers to a device that inputs and outputs information through a touch through a display unit.
In the present invention, the term "touch panel" refers to a panel that is configured to detect contact (i.e., touch) on a user's panel by electromagnetic driving principle and transmit related information.
In the present invention, "operation unit" means a module or a part capable of performing information processing.
Hereinafter, the present invention will be described in detail with reference to the drawings.
1 and 2 show a consonant keyboard layout for a Hangul character input method according to the present invention. Unlike ordinary keyboards, only consonants appear. The touch panel portion for inputting the consonant is referred to as a "consonant region", and a portion where a consonant, a vowel, or a combination of a consonant and vowel entered by the calculation processing appears is referred to as an "input window".
It goes without saying that any other method than the keyboard layout method shown in Figs. 1 and 2 may be applied.
Hereinafter, a method of inputting a Korean character according to the present invention will be described with reference to FIG. For illustrative purposes, reference is also made to the examples shown in Figs. 4-8.
In addition, it should be understood that a computing unit included in a portable electronic device equipped with a touch panel or an electronic device for a handicapped person performs information processing without describing a concrete act subject.
In the drawings, a portion where a touch is detected is indicated by a thick dot, and a portion where a touch is released is indicated by a plurality of radial lines.
Example One
As shown in Fig. 4 (1), when a touch of a consonant region is detected (S100), a consonant "i" corresponding to the consonant region is output through an input window (S110).
Next, the user drags in a vowel shape without releasing the touch (that is, while still touching the consonant). In other words, the user touches the area of the consonant "i" as shown in Fig. 4 (1) and then dragging the finger without releasing the finger to touch the locus in the shape of "a " A vowel "a" is calculated (S300), and a "character" is output in combination with the consonant (S400).
Example 2
As shown in Fig. 5 (1), when a touch of a consonant region is detected (S100), a consonant "i" corresponding to the consonant region is output through an input window (S110).
Unlike the first embodiment, which is a general case, when the touch release is detected without dragging as in (2) of FIG. 5 (S200), detection of the next touch is waited (S210).
If the next touch is detected, it is first determined whether the detected region is a consonant region (S220). In the case of the consonant region, the consonant "i" corresponding to the consonant region is confirmed, so that the consonant "i " confirmed at this time is combined with the consonant" If the pair consonant configuration is possible, the consonant "i" outputted in step S110 is deleted as shown in (3) of FIG. 5 and the configured consonant "?
As described in the first embodiment, the vowel is identified by starting from the touch detection of the consonant region and dragging without releasing, so that the user drags the vowel without releasing the touch detected in step S210. That is, the user touches the area of the consonant "X" for the second time to complete the consonant "?" As shown in Fig. 5 (4) Similarly, when the touch is released, the vowel "ㅗ" is calculated (S300). Thus, the song is combined with the consonant (S400).
Example 3
As shown in Fig. 6 (1), when a touch of a consonant region is detected (S100), a consonant "i" corresponding to the consonant region is output through an input window (S110).
As in the second embodiment, if the touch release is detected without dragging (S200) as shown in (2) of FIG. 6, the detection of the next touch is waited (S210).
If the next touch is detected, it is first determined whether the detected region is a consonant region (S220). The consonant " b "confirmed at this time is combined with the consonant" i "outputted in the first step S110 to check whether the consonant configuration is possible (S230) If the pair consonant configuration is impossible, the consonant "i" output in step S110 is not deleted as shown in (3) of Fig. 6, and consonant " (S240).
As described in
Example 4
As shown in Fig. 7 (1), when a touch of a consonant region is detected (S100), a consonant "c" corresponding to the consonant region is output through an input window (S110).
As in the second and third embodiments, when the touch release is detected without dragging (S200) as in (2) of FIG. 7, the detection of the next touch is waited (S210).
If the next touch is detected, it is first determined whether the detected region is a consonant region (S220). Since it is not a consonant region as shown in (3) of FIG. 7, a vowel is calculated using a drag trajectory starting here. That is, the user drags in a vowel shape without releasing the detected touch in step S210. When the user touched the finger as shown in (4) of FIG. 7 and dragged his / her finger without releasing the finger, the trajectory is drawn in the shape of "ㅐ", and when the touch is released, the vowel "ㅐ" is calculated (S300) Quot; is outputted (S400).
Example 5
As shown in Fig. 8 (1), when a touch of a consonant region is detected (S100), a consonant "a" corresponding to the consonant region is output through an input window (S110).
Next, the user drags in a vowel shape without releasing the touch. When it is confirmed that the user can not operate the vowel using the drag trajectory drawn by the user (S300) as shown in Fig. 8 (1) The drag trajectory is ignored and the next touch is awaited (S310).
If the user confirms that the trajectory is not calculated after dragging, the user touches the touch panel to draw the trajectory again. This is a touch for the vowel recognition. Therefore, in the case of a portable electronic device or an electronic device for a disabled person, It does not matter whether it is touching, touching another area or touching which part, so it does not judge it and only checks the drag trajectory.
That is, even if a touch is detected in the region of consonant "d" as shown in (3) of FIG. 8 (S320), "d" is not output, and only the drag trajectory is checked to calculate the vowel. As shown in (4) of FIG. 8, when the vowel "t" is calculated (S300), a phrase is output in combination with the consonant (S400).
The drag trajectory starting from the consonant "d " in Fig. 8 (4) draws a shape similar to the letter " a ", as in the vowel operation method described below, "ㅣ" and is calculated as a vowel "ㅜ" rather than a vowel ".". After recognizing "ㅡ", it must be recognized as "ㅣ" in upward direction and it is calculated as vowel "ㅓ". This will be described in detail below.
Further, as an additional or separate method for distinguishing "ㅓ" and "ㅜ", if the drag trajectory of the vowel starts from the right side based on the region of the consonant "a", it is recognized as "ㅓ" , The method recognized as "ㅜ" may be applied. It is a psychological way of inputting the keyboard of the "gig" and "gig".
Vowel operation method
As described above, the vowel calculation method of the present invention uses the drag trajectory of the user. Specifically, the user may touch the consonant and drag the consonant similarly to the shape of the vowel without releasing the consonant, thereby automatically recognizing the vowel portion of the portable electronic device or the electronic device for the disabled.
A specific method of recognizing vowels is to determine in what order and combination "ㅡ" and "び" are recognized during the drag.
First, the recognition method of "ㅡ" and "ㅣ" is as follows.
(-P < X < P) and "-" when the movement angle X in the rightward direction of the drag trajectory with respect to the horizontal axis is before or after the predetermined first angle P, And when the downward movement angle Y of the drag trajectory is before or after the predetermined second angle Q (-Q <Y <Q), it is recognized as "1".
That is, only the complete horizontal trajectory is recognized as "ㅡ", or only the complete vertical trajectory is recognized as "ㅣ". This is because recognition rate is low when only a complete horizontal or vertical trajectory is recognized.
Suitable P and Q values are preferably 5 to 15 degrees. If the value is too small, the recognition rate is low. If the value is too large, it is impossible to distinguish from left up / left down / right up / downward movement described below.
For example, if the movement angle X in the rightward direction is before or after the predetermined first angle P (-P <X <P) so that it can be recognized as "-" in the entire drag trajectory, (-Q < Y < Q) is one time of (1) when the moving angle Y in the downward direction is before and after the predetermined second angle Q so as to be recognized as " . Also, if the order is checked, the touch is released after being recognized in the order of "ㅣ", "ㅡ", "ㅡ". The vowel in this order is only the vowel "vowel" as shown in FIG. 9. Since this information is stored in advance in the database as will be described later, the calculation unit calculates the vowel "vowel" through it.
Next, the combination stored in the database for the operation of the operation unit is as shown in FIG.
Specifically, when the operation unit recognizes "ㅡ" and recognizes "ㅣ" as a vowel "ㅡ" when it is touched off, it recognizes "ㅣ" as a vowel "ㅣ" It is recognized as "ㅣ" or "ㅣ" in the leftward direction and "ㅡ" in the leftward direction. When the touch is released, it is recognized as "ㅗ" , "ㅡ" and then "ㅡ" in the upward or upward direction and then "ㅡ" in the downward direction. If the touch is released, the vowel "ㅑ" ㅣ "is recognized as" ㅣ ", then it is recognized as" ㅣ "in the upward direction or" ㅣ "in the upward direction. After recognizing it, it recognizes "ㅣ" in upward or upward direction, and when it is untouched, it returns to the vowel "ㅐ", "ㅡ" After recognizing "ㅣ" and recognizing it as "ㅣ" in the upward direction, if it is touched off, it will be recognized as "vowel", "ㅣ" , "ㅣ", then "ㅡ" in the upward or upward direction, then "ㅡ" in the leftward or downward direction and then "ㅣ" in the upward or upward direction. ㅡ "or" ㅣ "in the upward direction after it is recognized in the upward direction or" ㅣ "in the upward direction, and when it is touched off, it is recognized as the vowel" ㅖ " If it is recognized as "ㅡ" in upward or upward direction, if it is touched off, it is detected as "ㅘ", "ㅣ" or "ㅡ" If it is recognized as "ㅣ" in upward direction and it is untouched, it is detected as "ㅙ" ㅣ "on the left or the lower left, then" ㅣ "on the upward or upward direction after recognizing" ㅣ "on the upward or downward direction, After recognizing "up" in the upward or upward direction, it recognizes "ㅣ" in the upward direction after it is "ㅣ" in the upward direction or upward direction, and calculates it as the vowel "ㅞ" when it is touched off.
In the example shown in Fig. 11, when the arithmetic unit recognizes "?" At (1), "(2)" at the left, and (3)
In the example shown in Fig. 12, whether the arithmetic unit is "ㅡ" or not (③) after "ㅡ" in the upward or upward direction (③) (⑥) in the upward direction (⑥) or "ㅣ" in the upward direction (⑧) in the upward direction (⑨).
11 and 12 are merely described by way of example, and those skilled in the art will be able to fully understand the operation of other vowels.
In particular, it is important to distinguish between the vowel "ㅓ" and the vowel "ㅢ". For this purpose, it is necessary to recognize "ㅣ" ㅡ "is recognized as" ㅣ "in upward direction, and when it is touched off, it is calculated as vowel" ㅢ ".
Also, the distinction between the vowel "ㅠ" and the vowel "ㅟ" is also important. The order and combination are almost the same as shown in Fig. Therefore, even if it is recognized as "?" In FIG. 14 and then "?" In the left-downward or leftward direction and then "?" In the right-upward direction as shown in FIG. 14, If the value (d) obtained by subtracting the height (A) of the last recognized point of "ㅡ" is larger than a preset value, it can be classified by calculating with the vowel "ㅟ", and otherwise calculating it with "ㅠ".
When consonants and vowels are combined and outputted, consonants may be output when the consonants are input. Alternatively, the consonants may be consonants of the next character. The method of distinguishing the consonants and the vowels is conventional, and any method may be used. Do not.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the present invention can be changed.
