Description

Device and method for inputting Korean characters on touchscreen based upon fisheye effect, and electronic device using the same}

The present invention relates to a touch screen Hangul input method and apparatus based on fisheye effect, and an electronic device using the same. More specifically, the present invention selectively enlarges the size of the input key according to the basic principles of Hangul, thereby narrowing the display environment The present invention relates to a touch screen Hangul input method, device and electronic device using the same based on fisheye effect that can significantly reduce the input error that occurs in.

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 Hangul input device using a fisheye lens effect, a recording medium and a mobile device, in which a size of a Hangul input key on a touch screen is variably changed based on consonant-vowel-consonant connectivity. To provide.

An object of the present invention is to provide a Hangul input method of a method that can significantly reduce the input error of the user 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 fisheye effect, (a) after inputting the consonant consonants, the step of enlarging and displaying the vowel input area that can be combined with the consonant consonants ; And (b) after the vowel input region is input, the final consonant input region of the Hangul syllable to which the vowel belongs or the consonant input region of the next Hangul syllable is enlarged and displayed. Provide screen Hangul input method.

The enlarged vowel and consonant input area may include a vowel and a consonant input key on the touch screen.

In addition, the consonant consonant may be any one of o, k, k, k, k, h, and, if the consonant is a, c, k, k, k, the consonant after determining whether the consonant is consonant A vowel input key that can be combined with a consonant can be enlarged and displayed on the touch screen.

In another embodiment of the present invention, when another vowel cannot be combined with the input vowel, the initial consonant input key of the final or subsequent Hangul syllables coupled to the vowel may be enlarged and displayed.

In addition, the input vowel may be any one of ㅏ, ㅑ, ㅓ, ㅕ, ㅐ, ㅒ, ㅔ, ㅛ, ㅠ, ㅣ. If the input vowel is ㅗ, TT, ㅡ vowel and consonant input keys which can be combined with the vowel can be selectively enlarged.

The present invention provides a recording medium in which program instructions for performing the above-described touch screen Hangul input method are recorded.

In order to solve the above another problem, the present invention provides a touch screen Hangul input device based on the fisheye effect, the device includes a storage unit for storing the consonants and vowels of the Hangul; A display unit displaying the consonants and vowels of the Hangul; An input unit configured to detect a user touch input from the displayed consonants and vowels of the displayed Hangul; And a controller configured to enlarge and display a vowel input area that can be coupled to the consonant on the touch screen when the input consonant is a consonant. do.

In one embodiment of the present invention, if any one of the vowel input areas is input, the controller enlarges and displays the final consonant input area of the Hangul syllable to which the vowel belongs or the initial consonant input area of the Hangul syllable.

The consonant consonant may be any one of o, k, k, k, k, h, and h. If the initial consonant is a, c, k, k, k, the controller determines whether the consonant is a consonant of the consonant. A vowel input area that can be combined with a consonant can be enlarged and displayed on the touch screen.

According to an embodiment of the present invention, if another vowel cannot be combined with the inputted vowel, the controller may enlarge and display the initial consonant input area of the final or subsequent Hangul syllables coupled to the inputted vowel. The input vowel may be any one of ㅏ, ㅑ, ㅓ, ㅕ, ㅐ, ㅒ, ㅔ, ㅛ, ㅠ, ㅣ.

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 displaying many Hangul input keys of the same size on the screen, the user can easily enlarge and display input keys such as consonants or vowels based on the continuous input method of Hangul-neutral-neutral-jongjong. Hangul input can be performed.

To this end, the present invention noted that one syllable of Hangul is input in the order of consonant consonant, vowel consonant, and consonant consonant. 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 enlarges and displays an input key of a vowel to be input again after the initial consonant is input. This produces the same effect as enlarging the keyboard keys through a fisheye lens, so we call this a fisheye effect.

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

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

1, the Hangul input method according to the present invention comprises the steps of: after inputting the consonant consonants, the vowel input area that can be coupled to the consonant consonants is enlarged and displayed on the touch screen (S110); And after the vowel input region is input, the consonant input region of the Hangul syllable to which the vowel belongs or the initial consonant input region of the next Hangul syllable is expanded and displayed (S120). Here, the vowel input region or the consonant input region includes all regions of any type in which the vowel or consonant is displayed. For example, the entire area including all of the plurality of unit input keys (this is divided into consonants and vowels according to the type of input keys) may be the input area. One embodiment of the present invention is the consonant or vowel input area to be expanded, but the consonant or vowel input key itself, but the scope of the present invention is not limited thereto, and the entire area including the input keys may be expanded. It becomes the input area.

According to the present invention, when an initial consonant is input, the vowels coupled to the initial consonant are enlarged and displayed. Provide an input method.

2 and 3 are diagrams illustrating a Hangul input method according to an embodiment of the present invention.

Referring to FIG. 2, the consonant input key and the vowel input key are arranged on the left and right sides. In particular, in the initial state, the consonant input key having a high input probability is larger than the vowel input keys.

Referring to FIG. 3, the user touches and inputs "o" among consonants. In the case of "ㅇ", the consonant is not allowed to be consonant, so it is very likely that the vowel is input immediately after the "o" consonant. Therefore, after inputting "o", the vowel input key is enlarged. In this way, separate consonants are not allowed, and consonants into which vowels are input are ㅇ, ㅋ, ㅋ, ㅌ, ッ, ㅎ. However, in the case of consonants that allow paired consonants, the vowel input key may not be enlarged until the consonant is determined. .

However, in contrast, when a separate consonant input key is provided, the vowel input key may be enlarged and displayed immediately after the consonant input.

4 and 5 are diagrams showing a Hangul input method according to another embodiment of the present invention.

Referring to FIG. 4, when a pair of consonant input keys 410 are separately input, a, c, ㅂ, ㅂ, keyboard keys capable of paired consonants are expanded.

Referring to FIG. 5, as "a" is selected, "ㄲ" is displayed on the display unit, and the neutral vowel input key coupled to "ㄲ" is enlarged and displayed.

As described above, the Hangul input method according to the present invention expands the neutral vowel after inputting the consonant, and then expands the final consonant or the next consonant after inputting the neutral vowel, and then predicts the next input keys using the scientific principle of the Hangul. Selectively zoom in.

Therefore, even in the case of a vowel input after inputting a consonant consonant, it is determined whether the input key of the next consonant (the final consonant or the first consonant of the next syllable) is expanded according to the property of the input vowel.

6 is a diagram illustrating a Hangul input keyboard according to an embodiment of the present invention.

Referring to FIG. 6, in the Hangul input keyboard according to an embodiment of the present invention, input keys including initial ㅏ, 모음, ㅓ, ㅕ, ㅐ, ㅒ, ㅔ, ㅛ, ㅠ, ㅣ vowels are displayed. Since a separate vowel does not need to be combined with the vowel, when any one of the vowels is selected and inputted, the final consonant is immediately enlarged and displayed. However, another embodiment of the present invention provides a technical feature for converting the vowels into complex vowels, for example, ㅐ ㅖ and ㅖ by inputting the twin consonant input keys 410 of FIGS. 4 and 5, At this time, only the two keys having the highest input possibility can be further expanded than other vowel input keys. That is, the selection of the twin consonant input key 410, in particular, the touch of the twin consonant input key 410 in the vowel input order, the selection is for the user's composite vowel input, the present invention by the twin consonant input key 410 The converted compound vowels are enlarged larger than the other vowels for easier user input of the vowels.

In the present specification, the consonant input key 410 is a separate selection means or selection input key for converting a vowel or consonant into a compound vowel or consonant, and the present invention is not limited to the above name. Accordingly, any and all means capable of converting the initially displayed consonants or vowels into twin consonants or compound vowels all belong to the twin consonant input key 410.

If the vowels entered in the vowel input order are ㅗ, TT, ㅡ, the regularity is somewhat more complicated than the vowels described above, because complex vowels such as "ㅗ" "ㅘ" "ㅚ" "ㅙ" This is because a compound collection such as the vowel "TT", "" "," ㅟ "," ㅞ ", and the like can be made.

Thus, for example, after inputting the ㅗ vowel, the next vowel and consonant that can be input are selectively enlarged (both consonants, 모음, ,, ㅐ), or a separate input key enlargement is not performed. It may not.

FIG. 7 illustrates a state in which an input key is changed after a vowel is input in the Korean input keyboard of FIG. 6.

Referring to FIG. 7, since the vowels that can be combined into the vowels are “ㅣ”, the “ㅣ” vowel input keys are expanded together with the consonant input keys, thereby allowing the user to input a complex vowel with easier consonant input.

8 to 15 are diagrams showing an example of inputting a sentence "hello we" through the Hangul input method according to the present invention.

Referring to FIG. 8, first, an initial consonant "" is input, and after inputting "", the vowel input key is enlarged. When the vowel “ㅏ” is selected again, the consonant input key is enlarged (see FIG. 9), and when “n” is input again, the input consonant “n” is followed by an input consonant according to whether it is a consonant or a final consonant. Can be a vowel or consonant. Thus, in this case, the initial consonants and the vowel input keys have the same size (see Fig. 10).

Referring to FIG. 11, the vowel input keys are enlarged and displayed as “b” is inputted. After inputting "ㅕ" again, the consonant input key is enlarged (see FIG. 12), and the user touches "ㅇ" of the enlarged consonant input keys and inputs the completed Hangul syllable "Ning" (see FIG. 13). )

Referring to FIG. 14, after a user inputs "ㅇ" among consonant input keys expanded for consonant input, the vowel "TT" is input again, and a vowel input key (입력, And consonant input keys are enlarged and displayed.

Referring to FIG. 15, “L” is inputted by inputting “” among the enlarged consonant input keys and “” among the enlarged vowel input keys. Is 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.

16 is a block diagram of a Hangul input device according to an embodiment of the present invention.

16, a Hangul input device according to an embodiment of the present invention includes a storage unit (B10) for storing the consonants and vowels of Hangul; A display unit (B20) displaying the consonants and vowels of the Hangul; An input unit (B30) for detecting a user touch input from the displayed Korean consonants and vowels; And a control unit B40 for enlarging and displaying a vowel input key on the touch screen when the input consonant is a consonant. When the vowel input key is input, the controller B40 enlarges and displays the final consonant input key of the Hangul syllable or the initial consonant input key of the Hangul syllable to which the vowel belongs.

The function of the control unit is as described above, and if another vowel cannot be combined with the input vowel (this is determined according to the displayed vowel input keys, and if all vowels are displayed, the combination of the other vowels is If not, the control unit enlarges and displays the initial consonant input key of the final or subsequent Hangul syllables coupled to the input vowel. However, if a vowel in which another vowel is combined is input, the vowel and the consonant which can be combined with the vowel are enlarged. For example, if the input vowel is ㅗ,, ㅡ, it is a combination of "ㅘ" "ㅚ" "ㅙ" which can be input from "ㅗ", "ㅝ" "ㅟ" "ㅞ" which can be input from vowel "TT", etc. Since the vowel is a complex vowel such as "ㅡ" to "ㅢ", the vowel and consonant input keys corresponding thereto can be enlarged.

The present invention also provides an electronic device including the above-described Hangul input device. Herein, the electronic device includes any electronic device having a touch screen and capable of interfacing with a user. For example, a mobile phone, a netbook, an mp3 player, a notebook computer, a personal computer, and the like are examples of the electronic device. .
