Description

Hangul keypad, Hangul input device and Hangul characters generation method {keypad for korean, apparatus for inputting korean and method for generating korean}

The present disclosure generally relates to a Hangul input device, and more particularly, to a Hangul keypad, a Hangul input device, and a Hangul character generation method.

The keypad used in the portable communication terminal is composed of 12 keys for dial input. As Hangul is displayed on the LCD, Hangul input is also required in text messages. For this purpose, Korean input method using only 12 keys has been used. Unlike computer keyboards, you can complete the syllables by selecting the letter by hitting the keyboard one or three times to enter several consonants and vowels.

As keypad input increases the need for writing text messages while on the move, terminals that have taken advantage of convenience and efficiency have a direct impact on consumer choice. The 'Cheonjiin Hangul' keypad keyboard, which consists of 6 (consonants) + 3 (vowels), is widely used because the vowel input method is simple and easy to learn. In addition, the 'eZ Hangul' keypad keyboard composed of 7 (consonants) + 5 (vowels) is preferred because it has a lower hitting rate than the 'Cheonjiin Hangul' keypad keyboard. The above two methods occupy more than 95% of keypad keypad.

As the need for inputting characters increases in mobile terminals, terminals adopting full keyboards such as PC keyboards have become popular. Such a full keyboard does not need to learn a new keyboard when applied to a portable terminal, there is an advantage that does not need to be battered. However, there is a disadvantage that the size of the individual keyboard is so small that it does not function properly and the input is difficult.

In the present disclosure, consonants and vowels are placed on 12 keys, but the [first]-[vowel]-[final] are sequentially input without the battering process. The effects of the present disclosure greatly reduce the number of batters, allowing much faster input than the conventional method on the same 12 keys. The input of Hangul is '3 beolsik keyboard (Gongwoowoo's keyboard)' which inputs [choseong-vowel-jongseong] separately, and the 2 beolsik keyboard that divides [jongsung]-[choseong] into Korean automata. There is this. Other keyboards are available but are now extinguished. The PC keyboard has a double standard for the KS standard, but the keypad does not have a keyboard standard. In the present disclosure, since the keyboard input and the arrangement of the keys as intermediate forms of the 2 bee type and the 3 bee type are taken, a 2.5 bee type keyboard or a 2.5 bee type keypad is used to clarify the distinction and to facilitate quoting in the detailed description and drawings to be described later. Name it.

In the conventional mobile phone Hangul keyboard, Korean characters are inputted in many battering (continuous stroke) methods using six consonants and three vowels (Cheon-in keyboard) or seven consonants and five vowels (eZ keyboard). As a result, excessive input speed is slower than that of a PC keyboard.

In one embodiment, a Hangul input device for inputting Hangul characters is provided. The Hangul input device includes a keyboard including a plurality of numeric buttons on which basic consonants and basic vowels are arranged, and a character combiner for generating Korean characters through the basic consonants and the basic vowels input through the keyboard. The character combiner generates a Hangul character corresponding to the input basic consonant and the basic vowel, or selects any one of a compound consonant, a double consonant, a lattice sound, and a vowel in response to number buttons that are multiple breaks according to a predetermined pattern. Create one.

In another embodiment, a Korean keypad for inputting Korean characters is provided. The Hangul keypad includes a keyboard including a plurality of numeric buttons for inputting a basic consonant, a basic vowel, and a support key, and a number button of the keyboard to be input according to a predetermined pattern or each of the plurality of numeric buttons to be input. And a scan matrix for correspondingly generating scan codes. The scan matrix generates the scan code when at least one of the numbered buttons being released is released.

In another embodiment, a method of generating Korean characters is provided. In the method of generating Korean characters, first, a keyboard including a plurality of numeric buttons for inputting a basic consonant, a basic vowel, and a support key is provided. The Korean consonants are generated by receiving the basic consonants singly or in combination. The Korean vowel is generated by receiving the basic vowel alone or in a hit. The Korean consonants are generated by receiving the basic consonants singly or in combination. The support key is joined together in the process of generating the Hangul Jongjong and the Hangul initial and Hangul finality are generated separately from each other. The process of generating the Hangul consonants, the process of generating the Hangul vowels, and the process of generating the Hangul jongjong may include any one selected from among the consonant, double consonant, lattice, and the consonant in response to the number buttons to be joined according to a predetermined pattern. Create

The foregoing is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, additional aspects, embodiments, and features will become apparent by reference to the following detailed description and drawings.

Hereinafter, exemplary embodiments disclosed herein will be described in detail with reference to the accompanying drawings. Unless otherwise indicated in the text, like reference numerals in the drawings indicate like elements. The illustrative embodiments described above in the detailed description, drawings, and claims are not meant to be limiting, other embodiments may be utilized, and other changes may be made without departing from the spirit or scope of the technology disclosed herein. Those skilled in the art can arrange, configure, combine, and designate the components of the present disclosure, that is, the components generally described herein and described in the figures, in a variety of different configurations, all of which are expressly devised and It will be readily understood that they form part of.

In the present disclosure, the input of consonants for [choseong] and [jongseong] in the input of Korean characters is input of nine keys (a, b, c, d, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ), [vowel]. Limit to 10 keys (ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, ㅛ, ㅠ, ㅡ, ㅣ), and place [consonants] and [vowels] on 12 key keyboards effectively. Fast text entry is implemented in portable terminals such as key phones. Hereinafter, the contents of the present invention will be described in detail through one embodiment of the present disclosure.

1 is a diagram illustrating a Hangul input device according to an exemplary embodiment. 1A illustrates a conceptual diagram of a Hangul input device, and FIG. 1B illustrates a keyboard of a Hangul input device.

Referring to FIG. 1, the Hangul input device 100 includes a keyboard 110 and a character combiner 120. In some embodiments, the Hangul input device 100 may further include an optional display unit 130. In the drawing, a Korean input device 100 including a keyboard 110, a character combiner 120, and a display 130 is shown as an example.

The Hangul input device 100 may receive Hangul through the keyboard 110 and the character combiner 120. The keyboard 110 includes a plurality of numeric buttons for inputting basic consonants and basic vowels. In an embodiment, the keyboard 110 may further include a support key 104 disposed on any one of the plurality of numeric buttons. The support key 104 is combined with the number buttons input alone or alone to generate any one selected from among basic consonants, Bok consonants, lattice sounds, and layered consonants corresponding to Hangul finality. Can be generated. In another embodiment, the consonants or vowels selected from the basic consonants and the basic vowels may be arranged one by one by adding a key to the plurality of numeric buttons. This is called a first batch. Alternatively, one consonant and one vowel selected from the basic consonant and the basic vowel may be arranged in pairs in the plurality of numeric buttons. This is called a second batch. In the case of the first arrangement, the first Hangul consonants and the Hangul vowels may be generated by adding up the first consonants. In the case of the second arrangement, only one vowel selected from the basic vowels may be arranged on the number button on which the support key is arranged. As another embodiment, the keyboard 110 may further include a space and a delete key. In this way, spacing and deletion functions that occur frequently during input can be easily handled within the keyboard structure. In the drawing, in addition to the plurality of numeric buttons arranged on the keyboard 110, a mode key for selecting a text writing mode (numbers, Korean, English uppercase letters, English lowercase letters, etc.), and a send for sending a written Korean character. Also, a clear key for deleting a key and a written Korean character is also represented. The mode key, the send key, and the clear key may be disposed on any portion of the Hangul input device 100 other than the keyboard 110 or the keyboard 110. Operation and function of the mode key, send key, and clear key are substantially the same as the operation and function of a typical Korean input device, and thus a detailed description thereof will be omitted for convenience of description.

The character combiner 120 generates Korean characters through the basic consonants and the basic vowels input through the keyboard 110. The character combiner 120 generates a Hangul character corresponding to the input basic consonant and the basic vowel, or corresponds to a number of buttons that are multiple breaks according to a predetermined pattern. Any one selected from may be generated. According to an embodiment, the character combiner 120 scans the plurality of numeric buttons input or the numeric buttons of the keyboard to be joined according to the predetermined pattern with a scan code, respectively. And a scan code converter (not shown) for converting the scan code into the corresponding Hangul characters. The scan matrix may generate a scan code corresponding to the number buttons when at least one of the number buttons to be released is released. Alternatively, scan codes may be generated corresponding to the number buttons when the number buttons to be joined are simultaneously released. In the hitting, the scancode converter may convert the scancode into the corresponding Hangul character when at least one of the number buttons to be hit is released. Any buttons released after that are ignored. Alternatively, the scan code may be converted into the corresponding Hangul character when released at the same time.

The display 130 may display Korean characters input through the keyboard 110 and the character combiner 120. Since the function and structure of the display unit 130 are substantially the same as the function and structure of the display unit used in a typical Korean input device, a detailed description thereof will be omitted for convenience of description. When it is possible to recognize or notify the Hangul characters input by other methods such as voice, the display 130 may be omitted.

Hereinafter, the configuration and operation of the Hangul input device 110 of the present disclosure will be described in detail.

There are two cases of Hangul input order: [chosung]-[vowel], [chosung]-[vowel]-[jongsung]. In syllable input, [support] is selectively input, and [consonant] -vowel] is always input to complete the syllable. In the present disclosure, this is referred to as a [supercap] input. The syllable input starts with the [contrast] input, and the finality can be input by simultaneously pressing the support key and the consonant key sequentially (called break) and then releasing it. The Hangul consonant and vowel inputs of the present disclosure are characterized by sequentially processing a break (break) and a release (release) input of the scan code separately. In an embodiment, the keyboard 110 may have consonant and vowel arrangements as shown in FIG. 1B. The above example is an example for understanding, and the keyboard 110 may have various consonant and vowel arrangements as shown in the drawing. The scan code will be described later with reference to FIG. 2. Hangul consonant and vowel input of the present disclosure will become apparent from the following additional description. For simplicity, the following description will be made based on the consonant and vowel arrangement shown in the drawings. These descriptions do not limit the scope of the present disclosure, and it will be apparent that various modifications may be made at the level of those skilled in the art.

The first consonants of Hangul are all 19, and only 9 consonant arrangements are shown in FIG. In the present disclosure, these are called basic consonants. For basic consonants (a, b, c, d, k, k, k, o, k), press the corresponding initial key. The primary double consonants (ㄲ, ㄸ, ㅃ, ㅆ, ㅉ) can be input through horizontal hitting. In one embodiment, 'ㄲ' may be input by combining 'a' and 'c'. 'ㄸ', 'ㅆ', 'ㅃ' and 'ㅉ' combine 'ㄷ' and 'ㄴ', 'ㅅ' and 'ㅁ', 'ㅂ' and 'ㅈ' and 'ㅈ' and 'ㅇ' respectively Can be input. That is, 'ㄲ' may be input by sequentially inputting 'ㄱ' and 'c' adjacent to it horizontally. The same applies to the input of 'ㄸ', 'ㅆ', 'ㅃ' and 'ㅉ'. The initial lattice sounds (,,,, ㅌ,,, ㅎ) can be input through the basic consonants and the vertical consonants placed horizontally or vertically, including 'ㅁ' 101. In one embodiment, 'ㅊ', 'ㅋ', 'ㅌ', 'ㄷ' and 'ㅎ' are 'ㅈ' and 'ㅁ', 'ㄱ' and 'ㅁ', 'ㄷ' and 'ㅁ', 'ㅂ' and 'ㅁ' and 'ㅇ' and 'ㅁ' can be input sequentially and then released. Alternatively, at least one may be input after releasing sequentially.

All Korean vowels are 21, and only 10 vowel arrangements are shown in FIG. These are referred to as basic vowels in this disclosure. Basic vowels (ㅏ, ㅓ, ㅗ, TT, ㅡ, ,, ㅑ, ㅕ, ㅛ, ㅠ) can be entered by pressing the corresponding vowel key after initial entry. The Korean vowel vowels (ㅔ, ㅔ, ㅚ, ㅟ, ㅢ, ㅒ, ㅖ) may be input by combining the basic vowel with the 'ㅣ' vowel 103. In one embodiment, 'ㅐ', 'ㅔ', 'ㅚ', 'ㅟ', 'ㅢ', 'ㅒ', 'ㅖ' are 'ㅏ', 'ㅣ', 'ㅓ' and 'ㅣ', 'ㅗ' and 'ㅣ', 'TT' and 'ㅣ', 'ㅡ' and 'ㅣ', 'ㅑ' and 'ㅣ' and 'ㅕ' and 'ㅣ' can be entered sequentially and released at the same time. have. Alternatively, after inputting sequentially, at least one may be released. Additional double vowels (ㅘ, ㅝ, ㅙ, ㅞ) can be entered by combining basic vowels and double vowels. According to an embodiment, 'ㅙ' may be input by combining 'ㅗ', 'ㅏ' and 'ㅣ'. 'ㅣ' collection 103 is arranged independently from the scan matrix to facilitate rudder. Detailed description thereof will be described in detail with reference to FIG. 3.

There are 27 Hangul Jongjong, and among them, the base pads (a, b, c, d, ㅁ, ㅂ, ㅋ, ㅋ, ㅌ, プ, ㅎ) are input in the same way as the initial input. 104) is included in the hit. The rest is a composite stand. As a result, the base is increased by one more hitting than the initial. Since the Hangul initials are input without the supporting key 104, the Hangul initials and Hangul finality can be distinguished from each other at the time of joining. There are 13 compound bearings (double consonants and Bokja consonants) of Korean Jongjong based on the spelling of modern languages. 13 double and double consonants (ㄲ, ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄿ, ㄾ, ㅀ, ㅄ, ㅆ) need to be entered in multiple breaks and in one release There is. For this purpose, the 'ㄹ' key 102 is arranged independently so that it can be easily combined with other consonants, and each of them is added as follows. In one embodiment, the 'ㄳ' may be input by releasing after hitting the 'a', 'ㅅ' and the support key 104. In addition, 'ㄶ', 'ㄺ', 'ㄿ' and 'ㅄ' are 'B', 'ㅇ', 'ㅁ' and support key 104, 'ㄹ', 'ㄱ' and support key 104, respectively. , 'D', 'ㅂ', 'ㅁ' and support key 104 and 'ㅂ', 'ㅅ' and support key 104 may be input after releasing. The other consonants may be input in substantially the same way. The syllables in which these compound consonants are used are, for example, 'to experience', 'soul', 'sit', 'not', 'bright', 'transfer', 'step on', 'outside', 'lick', 'out', It can be 'right', 'no', 'was', and so on. Most of these compound consonants are often used less frequently. Therefore, although the number of final inputs may be up to four, the input frequency is extremely low, and most of the final inputs may be completed by two hits except the support key 104.

FIG. 2 shows keys requiring independent input to avoid collisions in scan matrices (not shown) when combined with the assignment of scancode values 110A. The scan codes S0, S1, S2, S3, S4, S5, S6, S7, S12, S15, S22, S23, S31, S33, and S35 are displayed to the right of the numerals of the keyboard 110A. In initial hitting, 'ㅁ' 101 requires independent input. In vowel matching, the '103' requires independent input, and in the final hapta, 'ㄹ' (102) requires independent input for complex species input. Make it easy to distinguish. At the end, the backing key 104 is arranged as an independent input to support compound consonant hitting.

FIG. 3 shows scan codes of keys 101, 102, 103, and 104 that require independent arrangement in a scan matrix configuration 300 consisting of a scan row (output signal) and a scan column (input signal). And its location. There is also a key S1 that requires a position change to avoid collisions in the scan column. When scan lows a0, a1, a2, and a3 are sequentially low, the input columns of the CPU are changed in the scan columns d0, d1, d2, d3, d4, d5, d6, and d7. Read scan column values in the pullup state. When a key is input, the corresponding bit goes low to detect it. It also detects this when the key is released. Since a process of processing a valid input value is the same as a normal keyscan process, a detailed description thereof will be omitted for convenience of description.

S4 (102), S6 (101) and S7 (103) are frequently used for hitting, so they are placed in separate input columns so as not to overlap with columns of other keys. S1 (number '3') is moved to the scan matrix (a1-d3) and placed so that 'b' and 'ㅇ' (or 'ㅎ') are not located in the same column when the supporting double consonant 'ㄶ' is combined. . This is necessary when placing only consonant keys. In the present embodiment, the letters are overlapped on the same key, so that S7 is arranged independently to independently input the vowel '|, and the columns do not overlap each other.

In the case of hitting, the scan code inputted as the key input value is not immediately converted to the key value, and all the input scan codes are stored in the buffer. When at least one of them is released, the hammering code is recognized. Alternatively, it can be input while released at the same time. In this process, the input order of the keys participating in the hit is ignored. In this way, the inputter can be free in the pressing sequence of the hapta key. When the release of one letter is completed, the final input letter is determined, and the Hangul initial and Hangul finality are also distinguished according to the support key 104. Therefore, there is no need for an automata to distinguish between Hangeul first and Hangeul last, and there is no so-called 'ghostfire' phenomenon in which wrong support is temporarily displayed when displaying intermediate input values.

Hangul syllables must be completed with at least a consonant and a vowel. Therefore, if only the final key is distinguished in the sequential input process of [chomo], [chomo seedling], the initial and the finality can be distinguished well. In other words, after entering the initial consonants, the consonants and vowels are assigned to the vowels without any confusion. Since the finality is distinguished by the hitting of the support, the keyboard of the present disclosure may also be referred to as a 2.5-large final keyboard.

As another embodiment of the present disclosure, a 20-key keyboard composed of 4x5 scan matrices may be configured so that the consonants and the vowels may be separately arranged in 19 pieces. As a result of the consonant key and the vowel key being separated, it is possible to input the pairing of the finality separately after the selection and pressing the consonant and the vowel simultaneously. In this case, after the [chomo] hitting, the finality can be distinguished from the [chomo] hitting because the vowel key is not pressed. Thus, a separate backing key may not be needed to distinguish between species. Therefore, it is not necessary to input the [Summo] simultaneous input and the [support] key, so it is possible to input more quickly. This corresponds to another embodiment of the present disclosure, and the other embodiment of the present disclosure provides a detailed description of an embodiment of the present disclosure in which consonants and vowels are placed on the 12 keys described above with reference to FIGS. 1 to 3. Since it can be sufficiently understood through the description, a detailed description thereof will be omitted for convenience. The 20-key keyboard described above is an example for explaining simultaneous hitting of the initial and vowels, and is not intended to limit the keyboard to the 20-key keyboard. For example, the keyboard capable of collapsing the supercap may further include various function keys. The various function keys may be, for example, a space key, a del key, and the like.

4 is a flowchart illustrating a method of generating a Korean character for inputting a Korean character, according to an exemplary embodiment. Referring to FIG. 4, in block 410, a keyboard including a plurality of numeric buttons for inputting a basic consonant, a basic vowel, and a support key is provided. In block 420, the basic consonants are input alone or in combination to generate a Hangul consonant. In block 430, the basic vowel is input alone or in a hit form to generate a Korean vowel. In block 440, the basic consonants are input singly or in combination to generate Hangul Jongjong. The support key is joined together in the process of generating the Hangul Jongjong and the Hangul Choson and Hangul Jongjong are generated separately from each other. The process of generating the Hangul consonants, the process of generating the Hangul vowels, and the process of generating the Hangul jongjong may include any one selected from among the consonant, double consonant, lattice, and the consonant in response to the number buttons to be joined according to a predetermined pattern. Create Details of each block are substantially the same as those described above with reference to FIGS. 1 to 3, and thus a detailed description thereof will be omitted for convenience of description.

The Hangul input device of the present disclosure is configured as a break-releaser, and the syllables inputted as [chomo] or [chomo seedling] may be converted into code values of a 2 beol type input keyboard and transmitted and displayed. This disclosure illustrates a keyboard layout that avoids collisions that may occur when using 'double' consonant hits by placing 'ㅁ' 101 to the right of 's' in consonant hits of the initial or the final consonant, and this arrangement is the most appropriate placement. However, it is also possible to rearrange "o" or "b" for use in double consonants, and in this case, it is consistent with the spirit of the present disclosure. The scan matrix described above with reference to FIG. 3 should be understood as an example for the sake of optimized implementation. Scancode processing with all 12 key values as independent inputs is possible without the configuration of the scan matrix, and in this case, even if a Korean or English selection key or the like cannot be added, it is included in the scope of the present disclosure. will be.

The present disclosure has been described in detail with regard to the Hangul input device which increases the number of battering and eliminates battering by arranging the alphabets on 12 keys in duplicate. The input of consonants and vowels can be handled in one hit (non-strike). In the Hangul alphabet input, the input time of summing about three keys is not significantly different from one battering time. In particular, when the keyboard layout and battering are used, the simultaneous release time may be equal to one release time, and the input time may be equal to 1 key input time. In this case, the input time is proportional to the number of batters. Therefore, as the batter is less, the Jamo input speed can be increased.

Cheonjiin uses 7 consonants and needs up to 3 batters, but 2.5 beacons use 9 consonant keys (2 additional), and the initial input ends with 2 hits and 1 batter off. The final input can be terminated with a maximum of 4 double inputs and 1 double release even on a double consonant. Cheonjiin needs to input up to 5 batters (in case of input of ㅙ, ㅞ, etc.) with 3 vowel keys for vowel input. The vowel can be entered, and the input can be terminated by releasing one hit. Like this, in the initial, vowel, and finality, one batter is allotted. Instead, the batter is increased. However, input within four batters is allowed to input the double speed, so the input speed is less affected. Therefore, the number of batters is more limited than the batter. Therefore, the input speed can be improved as much as the batter is reduced.

In the absence of a keypad standard and in the presence of different keyboard layouts, it may be difficult to learn another Hangul keyboard layout and input method through the 2.5 seed keyboards of the present disclosure. However, the number of the keyboard is less than 10, and the composition of the Hangul alphabet has a merit that quickly becomes accustomed to forming a hit on the Jamo associated with each other. In particular, an input speed that is fast enough to cause a user's Hangul input synchronization can be realized even with 12 keypads. While pressing the two or three keys at the same time in the batting process, there is a problem that the force is applied more, but this can be solved by the adjustment of the force applied to the keypad. In one embodiment, the haptic keypad implemented as a touch sensor keyboard can be a faster input with less fatigue of the wrist.

Since the input of the 2.5 beol-type keyboard named in the present disclosure distinguishes the finality, there is no so-called 'ghost fire' phenomenon in the 2 bee-type Hangul keyboard input so that the input value can be more stably confirmed. In addition, unlike 3 beol-type keyboards, since they share the initial consonant keyboard without separately placing the final keyboard, it is easy to learn the arrangement of the keyboard while utilizing the convenience of the 3-Bell type that inputs complex consonants as one stroke. In FIG. 1, space and dell keys are added to easily handle spacing and deletion functions frequently occurring in the keyboard structure.
