Abstract

PURPOSE: A device and method for inputting Korean letters on a touch screen based on consonant-vowel conversion are provided to remarkably reduce an input error which is generated in a narrow display environment by selectively converting the active area of input key according to a basic rule of Korean alphabet based on consonant and vowel. CONSTITUTION: A storage(B10) stores the consonant and vowel of Korean alphabet. A display unit(B20) displays a Korean alphabet keyboard including input keys of the vowel and consonant of the Korea alphabet. An input unit(B30) detects a touch input from consonant and vowel of the displayed Korean alphabet. If the inputted consonant is an initial sound consonant, a controller(B40) activates a vowel input key which can be combined to the initial sound consonant. The controller inactivates a consonant input key according to the activation of the vowel input key. If the collection input key is activated, the input area of the collection input key is expanded and the input area of the consonant input key is reduced.

Description

Device and method for inputting Korean characters on touchscreen based upon consonant-vowel conversion, and electronic device using the same}

The present invention relates to a touch screen Hangul input method, apparatus, and an electronic device using the same based on a Jamo transform, and more particularly, by changing a consonant-vowel input key activation state according to the basic principles of Hangul. The present invention relates to a touch screen Hangul input method, a device based on a Jamo transform, and an electronic device using the same.

Recently, as the electronic devices become smaller, a new character input method that can effectively implement Hangul input is required. In particular, Koreans are much more likely to input Hangul than to input English, so it is urgent to develop a reduced-size character input device provided with a keypad to easily input Hangul.

Furthermore, a touch method for generating an input signal according to a user's touch gesture is used as a general interface method of a mobile device.

If you touch a character or a specific location on the screen (or screen) without touching the keyboard or the keypad, the touch method detects the location and inputs it directly on the screen so that specific processing can be performed by the stored software. Describe how you can receive data. In general, the touch panel is coated with a resistive material on a glass or transparent plastic plate, and is a pressure type (Resistvie Overlay) that recognizes the position due to the change of resistance upon contact, and a surface ultrasonic method (Surface) that recognizes the touch point due to the interference of sound waves. Acoustic Wave), Capacitive Overlay that recognizes touch points by analyzing high frequency waveforms, and Infrared Beam that recognizes touch points by placing infrared light emitting elements and light receiving elements facing each other.

These touch technologies are applied to a mobile environment to increase users' usability, but as the size of the terminal decreases, the possibility of input error increases. In particular, a situation in which multiple Hangul input keys of a small size are simultaneously provided to a smaller touch panel makes it difficult to accurately perform a complicated Hangul input.

Accordingly, an object of the present invention is to provide a Korean input device, a recording medium, and a mobile device, in which the active area of the Korean input key on the touch screen is variably changed based on the consonant-vowel-consonant connectivity.

The problem to be solved by the present invention is to provide a Hangul input method of the method that can significantly lower the user's input error and a recording medium for performing the same.

In order to solve the above problems, the present invention provides a touch screen Hangul input method based on the Jamo conversion, (a) any one of the consonant input keys of the Hangul keyboard displayed on the touch screen is input to the consonant; (b) vowel input keys that can be coupled to the consonant are activated on a touch screen; And (c) after one of the vowel input keys is input, activating the final consonant of the Hangul syllable to which the vowel belongs or the consonant input key of the next Hangul syllable is activated. Provide an input method.

In one embodiment of the present invention, the Hangul keyboard has a structure in which a consonant input key and a vowel input key alternate with each other, and a consonant input key may be deactivated as the vowel input key is activated.

In another embodiment of the present invention, as the vowel input key is activated, the input area of the vowel input key is enlarged and the input area of the consonant input key is reduced.

In the Hangul keyboard, consonant input keys and vowel input keys alternate with each other in at least some areas, and the initial consonants are any one of?, ㅁ, ㅋ, ㅌ, ㅍ, ㅎ. In addition, when the consonants are a, c, ㅂ, ㅅ, ㅈ, after determining whether the consonants are consonants, a vowel input key that may be coupled to the consonants may be activated.

In another embodiment of the present invention, if another vowel cannot be combined with the inputted vowel, a consonant input key corresponding to the finality of the final vowel or subsequent Hangul syllables coupled to the vowel is activated.

The present invention provides a recording medium having recorded thereon program instructions for performing the above method.

In order to solve the above another problem, the present invention provides a touch screen Hangul input device based on the Jamo conversion, the device includes a storage unit for storing the Hangul consonants and vowels; A display unit displaying a Hangul keyboard including the Hangul consonants and vowel input keys; An input unit to detect a user touch input from the displayed consonants and vowels of the displayed Hangul; And a controller for activating a vowel input key that can be coupled to the consonant, when the input consonant is a consonant.

In one embodiment of the present invention, the control unit deactivates the consonant input key according to the activation of the vowel input key, and as the vowel input key is activated, the input area of the vowel input key is enlarged and the input area of the consonant input key is reduced. Can be.

In an embodiment of the present invention, the input keys of consonants and vowels are alternately displayed on the display unit, and the consonants and vowel input keys of the Hangul keyboard displayed on the display unit may be alternated in some areas of the keyboard.

In addition, the vowel activated and the deactivated consonant input keys may be visually distinguishable from the display unit.

In one embodiment of the present invention, after any one of the activated vowel input keys is input as a vowel, the control unit activates an input key of a consonant corresponding to the first consonant or the first consonant of the next Korean syllable that is coupled to the vowel. If another vowel can be combined with the inputted vowel, the controller may activate an input key of another vowelable vowel after inputting the vowel.

Unlike the conventional method in which the consonant-vowel (key) input keys are equally activated on the screen, the present invention selectively converts the active area of the input key based on the consonant-vowel according to the basic principles of Korean characters, thereby narrowing the display environment. This can significantly reduce the input errors that occur at. Furthermore, since the order of consonants-vowels and vowels can be optimized according to the Hangul input method, the input speed can be reduced and the input speed can be increased to significantly improve the Hangul input efficiency on the touch screen.

In order to fully understand the present invention, the operational advantages of the present invention, and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings which illustrate preferred embodiments of the present invention and the contents described in the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In addition, in order to clearly describe the present invention, parts irrelevant to the description are omitted, and the same reference numerals in the drawings indicate the same members.

Throughout the specification, when a part is said to include a certain component, this means that it may further include other components, without excluding other components unless specifically stated otherwise. In addition, the terms '.. part', '.. group', '.. module', '.. block', etc. described in the specification mean a unit that processes at least one function or operation, which is hardware or software. Or a combination of hardware and software.

According to the present invention, unlike the prior art of activating the same consonant input key or displaying consonant vowels simultaneously through separate consonant conversion keys, the consonant vowels are displayed on one display, but the consonant vowels are activated. Is optionally converted according to the nature of the Hangul input.

In more detail, the Hangul is input in the order of consonant consonant, vowels neutral, and consonant consonant (or consonant consonant of another Hangul syllable). That is, if a consonant is input, the vowel must be selected as a neutral next, and after the vowel input, a consonant consonant belonging to the syllable or a subsequent consonant of the next Korean syllable must be input. This law can be summarized as follows.

(1) primary consonant-neutral vowel-final consonant

Ex) Inside: "ㅇ" → "ㅏ" → "ㄴ"

(2) primary consonants-neutral vowels-final syllables of the next syllable

Ex) We "" ㅇ "→" ㅜ "→" ㄹ "

As shown above, Hangul input is the method of inputting consonant consonant-neutral vowel-final consonant or consonant of the next syllable. Accordingly, the present invention activates the consonant input keys in the order in which the first consonants should be input, and vice versa in the order in which the vowels should be input. In particular, the present inventor does not simply change the order of active consonants and vowels, but contiguous consonant input keys and vowel input keys. In the order in which the consonant input keys are activated, the adjacent vowel input key areas have a boundary area between the consonant input keys. Therefore, the input error by the adjacent consonant input keys can be reduced.

1 and 2 are partially enlarged views of a Hangul input key according to an embodiment of the present invention.

Referring to FIG. 1, a vowel “” is disposed between the consonant input keys “” and “”. Only "ㅂ" and "ㅈ" are activated in the order of input of the consonant of the first consonant. In FIG. 1, the activated part is grayed out. At this time, according to the activation of the consonant input keys, the vowel input keys therebetween are deactivated, thereby keeping the activated two consonant input keys (ㅂ, ㅈ) spaced apart from each other by a predetermined distance. In one embodiment of the present invention, the activated consonant input key is in a state in which its input area (this means an effective area into which consonants or vowels can be input by touching a corresponding area) is widened, thereby Even when the approximate point is touched, the consonant input key of the approximate position may be touched and input.

As shown in FIG. 2, "ㅂ" is displayed as an initial consonant by touching "ㅂ" among the activated consonant input keys "ㅂ" and "ㅈ", and then the vowel input keys are activated by crossing the deactivated consonant input keys. do. At this time, the input area of the vowel input key is expanded to the consonant input key area. In FIG. 2, the input area A of the vowel “ㅠ” is extended to the adjacent “ㅂ” and “ㅈ” areas, and the input area of the consonant input key is shown. Is reduced. That is, another embodiment of the present invention provides an effective Hangul input method using alternating consonant-vowel input keys by enlarging and reducing the input area of a corresponding type of input key.

3 is an overall view of a Hangul input keyboard according to an embodiment of the present invention.

Referring to FIG. 3, in the Hangul input keyboard according to the present invention, a vowel input key is arranged between the consonant input keys and a consonant input key is arranged between the vowel input keys. Has As a result, when the consonants are inputted, only consonants are activated, and thus the input keys that can be input by the actual user become consonant input keys spaced apart by the vowel input key width as shown in FIG. 4. On the contrary, in the order in which the vowels are input, only vowel input keys spaced by the size of the consonant input keys are activated as shown in FIG. 5, thereby avoiding an input error caused by accidentally touching an adjacent vowel input key. Furthermore, the present invention enlarges the actual effective area by expanding the input area of the input key of the activated type to the range of other non-activated input keys as described above. This produces the same effect as enlarging the keyboard through the lens.

Hereinafter, the Hangul input method according to the present invention will be described in detail with reference to the accompanying drawings.

5 is a step diagram of a touch screen Hangul input method according to an embodiment of the present invention.

Referring to FIG. 5, the Hangul input method according to the present invention is a touch screen Hangul input method based on a consonant conversion. The method includes inputting one of consonant input keys as an initial consonant in a Hangul keyboard displayed on a touch screen (S110). ); Vowel input keys that can be coupled to the consonant are activated on the touch screen (S120); And after inputting any one of the vowel input keys, the end of the Hangul syllable to which the vowel belongs or the consonant input key of the next Hangul syllable is activated (S130). In the Hangul keyboard, a consonant input key and a vowel input key are arranged to alternate with each other. Thus, a vowel input key is arranged between the consonant input keys and a consonant input key is arranged between the vowel input keys. Through the layout of the keyboard, an error in which a user touches an adjacent consonant by mistake as the consonant input key is activated can be reduced, and an error in which the user touches and inputs an adjacent vowel by mistake as only the vowel input key is activated. Can be prevented.

Another embodiment of the present invention provides a configuration in which the consonant input key region (consonant region) and the vowel input key region (collection region) alternate in a predetermined region (alternative region) instead of the entire consonant and the vowel input key alternately. do.

6 is a schematic diagram of a keyboard in which the vowel input key area and the consonant input key area alternate and cross only in a predetermined area (alternative area) according to the embodiment of the present invention.

Referring to FIG. 6, the consonant input keys of the keyboard alternate only with the input key of the vowel area and only in the predetermined area, and only the consonant and the vowel input keys are disposed on the left and right sides, respectively. As a result, the boundary effect of consonants and vowels can be prevented to a certain level. In this case, the user who is familiar with the QWERTY configuration with consonants on the left and vowels on the right can remember the existing input pattern as it is, and it does not require much time and effort for learning. The error reduction effect can be maximized by using the consonant ordering rule.

7 and 8 are diagrams illustrating an example of inputting Hangul according to a Hangul input method according to an embodiment of the present invention.

Referring to FIG. 7, since an initial consonant is to be input, consonant input keys are activated by a predetermined distance.

Referring to FIG. 8, when the user touches and inputs "o" among consonants, "o" is input, and at the same time, vowel input keys that can be combined with the consonant "o" are activated. Upon activation, the input area (effective area) of the vowel input keys is expanded to the adjacent consonant input key area, and the input area of the adjacent consonant input key is reduced. In this case, the consonant input key remains active, but only its input area may be reduced, which is also within the scope of the present invention.

As described above, all or part of the vowel input keys are disposed between the consonant input keys, and the consonant input keys are deactivated according to activation of the vowel input keys.

Referring to FIG. 9, the user inputs a vowel by touching a vowel input key activated at a predetermined interval after inputting the consonant of FIG. 7. This completes the Hangul syllable "Ah". After that, the consonant input keys of the final consonants or the separate consonants which can be combined with the vowels are activated.

10 and 11 are diagrams showing a Hangul input method according to another embodiment of the present invention.

Referring to FIG. 10, when a user inputs a pair of consonant input keys 410 displayed on a touch screen separately, a, c, ㅂ, ㅅ, 가능한, which are available for twin consonants, are activated after being changed into twin consonants.

Referring to FIG. 11, when a user inputs any one of the displayed double consonant input keys, all or part of the vowel input keys arranged between the consonant input keys are activated again, The Hangul syllable "Ka" is completed and displayed.

According to the present invention, even in the case of a vowel input after inputting a consonant consonant, whether the next consonant (the final consonant or the first consonant of the next syllable) input key is activated according to the characteristics of the input vowel.

12 and 13 illustrate a Hangul input method according to another embodiment of the present invention.

Referring to FIG. 12, the vowel input keys such as initial ㅏ, ㅑ, ㅓ, ㅕ, ㅐ, ㅔ, ㅛ, ㅠ, ㅣ are displayed on the Korean input keyboard according to an embodiment of the present invention. Since the vowels do not need to be combined with the vowels, when any one of the vowels is selected and input, the final consonants or the first consonants of the next Korean syllable are immediately activated.

However, when the input vowel is ㅗ, TT, ㅡ, etc., it is somewhat complicated, because complex vowels such as "ㅗ" to "ㅘ" "ㅚ" "ㅙ" are possible, and the vowel "TT" to "ㅜ" This is because a compound collection such as "ㅟ" and "ㅞ" can be a compound collection such as "ㅢ" from the vowel "-".

Thus, for example, after entering the "ㅗ" vowel, the next vowel and consonant that can be input are selectively activated (both consonants, 중, ,, ㅐ), or no separate input key activation is performed. Can be. Among the input keys, the activated input keys may be distinguished and displayed in a visual manner. For example, a method of making the object of the deactivated input keys translucent may be possible. However, the scope of the present invention is not limited thereto, and the input keys activated in various ways may be displayed separately.

Referring to FIG. 13, after the vowel “ㅡ” is input, the vowels that can be combined with the “ㅡ” vowel are “ㅣ”, so that the “ㅣ” vowel input key is activated together with the consonant input key, thereby allowing the user to easily consonant. Compound vowel input is possible with the input.

According to the present invention, the Hangul Principle of the rule that the input of the consonant-vowel-consonant is repeated and the rule that the next consonant-vowel can be predicted according to the type of the consonant and the vowel can be applied to the Hangul input of the mobile device as it is. By applying it, the Hangul input error of the user is lowered.
