Description

Hangul input method and device based on new expanded keypad

The present invention relates to a Hangul input method and system for inputting Hangul by utilizing a numeric keypad used in a terminal such as a phone, a mobile phone, a computer, and more particularly, to conveniently and efficiently input numbers and characters including at least Hangul. A method and apparatus for

The character input code (KICS.KO-05.0018) using an electronic telephone, which was decided as a standard in 1992 by the Telecommunications Technology Association (TTA), was uncomfortable and attempted to standardize a new Korean input method in 1998, but failed. .

Meanwhile, with the rapid spread of mobile phones, mobile phone handset manufacturers such as Samsung Electronics, LG Information Communication, Hyundai Electronics, and Motorola have developed and applied their own Hangul input method.

In order to express Korean characters on the keypad used in mobile phones, the first method is to arrange consonants and vowels properly on the keypad, and the second is to combine letters by creating 'consonants' and 'vowels' according to specific rules. have.

The first method is to print 14 consonants and 10 vowels on 12 number buttons on the existing keypad. Therefore, it is inconvenient that several key-in is needed to input a specific consonant / vowel. there was. In more detail, existing patent application methods for inputting Hangul using the keypad generally use the 12 numeric buttons of the existing keypad as they are, so that the Korean consonants (basic consonants, lattice sounds, and multiple consonants) ) 2 ~ 4 are arranged in duplicate, Hangul vowels (basic vowel, middle vowel, double vowel) also arranged in duplicate by 2 ~ 3, to repeatedly key-in the number button a predetermined number of times. As a consonant and vowel, you can select the desired Hangul consonants and vowels. As a combination of the corresponding consonants and vowels, the letter input speed is very slow. To solve the problem of printing too many consonants and vowels on one number button In the case of double consonants or double consonants, the function keys (* or #) provided on the keypad were used together.

In this method, the number of key-in required when selecting a consonant or a vowel of a single character is very high. This resulted in a slower stroke compared to handwriting. As a method of changing consonants and vowel positions arranged on the numeric keys, or selecting a consonant consonant or a vowel vowel, the method of determining the number of key-in or using a separate function key is mainly used in the existing keypad. Emphasis was placed on how to arrange consonants effectively. However, there is a disadvantage in that the user friendliness is inferior, and there are too many key ins for combining letters.

The second method is to create 'consonants' and 'vowels' according to the specific rules of Hangeul, so that all consonants and vowels do not need to be printed on the number buttons on the keypad. By doing so, the user interface is good. There are 'Cheonjiin' Hangul input method used by Samsung and 'Naratmal 2000' used by LG.

The Korean input device and method based on the Cheonjiin Discipleship principle (Patent Application 99-52650) used by Samsung adopts Cheonjiin (? ㅡ ㅣ) method, and arranges the Hangul vowel on three numeric key buttons on the keypad. Distribute Korean consonants to seven number key buttons and combine the vowel inputs with letters. In another example, a double vowel or a double consonant is input by an operation using a combination of function keys (* or ＃) provided on the telephone keypad.

In this way, in the case of 'Cheonjiin', the simplicity of Hangul input is improved. However, the number of input keys necessary to key-in the button for the character expression is increased, making it difficult to express faster strokes than handwriting. The Korean input method used by LG separates consonants into 'double consonants' and 'compjamas' respectively, but the user needs to know how to use newly and input necessary to key-in the button to express characters. There is a disadvantage that many strokes are inconvenient.

Hangul is inconvenient and inefficient in terms of the number of key-in using the above-described input method, such as initial, neutral, and final, compared to English letters.

For example, due to the excessive use of key-in or function key to express the double consonant, the middle consonant, the middle vowel, and the double vowel described above, the fingering is long and the number of hits increases, which makes the usage very complicated. There is an inconvenience to learn how to learn.

Accordingly, an object of the present invention is to make a user interface easy to select and input a large number of characters without damaging the shape of the existing keypad as much as possible. To this end, the present invention is to place a new button, a text button in the free space of the existing keypad, to provide a convenience to the user's hand by preventing the difference between the height and height of the numeric key and the text key to prevent typos.

For example, traditional telephone keypads have numbers 0-9 and? * ?,? #? There were 12 numeric buttons for expressing characters, but there is a flat keypad space between these numeric buttons (hereafter referred to as numeric keys), in which the space is usually formed in a flat or slightly raised form with the keypad. Appearance was often the case. In the present invention, instead of using only 12 numeric buttons existing on the existing keypad, requesting a way to use the space of the space existing between the numeric button and the numeric buttons in the keypad, by placing a new character button here As a way to form, the user has many choices, and 19 out of 21 vowels are represented by one key-in.

Accordingly, at least the necessary number of key-in required for the initial and the neutral and finality, and the excessive use of the function keys, while reducing the excessive use of the function keys, while improving the input stroke speed by appropriate key placement of consonants and vowels Not only can it achieve faster speeds, it can also guarantee fast speeds in simultaneous input of numbers and letters, and it can reduce typos caused by duplicate key-in of users.

The present invention, while maximizing the space of the keypad, for the convenience of the user and the efficiency of using the keypad by placing a separate button in the empty space between the number buttons on the existing keypad, by allowing the user to receive input, simplicity of character input And optimizing learning ease.

In the present invention, in utilizing the empty space between the numeric button and the numeric button, by placing the numeric button slightly lower on the keypad, by placing the empty space between the numeric buttons on the keypad slightly higher by placing an alphabet button here In addition, the user can prevent a mistake in the button input between the numeric button and the alphabet button as much as possible, and the number of inputs per character can be reduced as much as possible by increasing the number of buttons selectable by the user.

In order to achieve the above object, the Hangul input method and apparatus by the expandable keypad according to the present invention, the Hangul consonants arranged on the numeric buttons of the expandable keypad and Hangul vowels on the character buttons, each key button When the code assigned to the corresponding key button is generated according to the permission of the selected key button operation, the Hangul alphabet generation process generates the Hangul alphabet corresponding to each generated code and combines them according to the combination principle of initial, neutral, and final. It is characterized by generating Hangul syllables. At this time, the order of assigning Hangul consonants to the numeric buttons of the expandable keypad and the order of assigning Hangul vowels to the character buttons of the expandable keypad may vary according to embodiments of the present invention.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail as follows.

1 is a block diagram of a numeric keypad of a telephone type to which an embodiment of the present invention is applied.

Referring to FIG. 1, the controller 110 controls the overall operation of the keypad. Memory 120 stores a program for controlling the overall operation of the keypad, and serves to temporarily store the input / output data when the overall operation is performed by the controller 110. The display unit 130 changes a backlight light attached to a button of a keypad according to an operation of a user's key or displays numbers and letters as a signal applied through the controller 110 to a connected LCD. The key input unit 140 is a key part of the present invention and has a function key used for a special purpose and a character key proposed by the present invention, in addition to the numeric keys configured on the existing keypad, and when the user presses a predetermined key through the keypad, The signal is applied to the control unit 110.

2 is a flowchart illustrating an embodiment of a method of inputting Korean using a keypad proposed in the present invention.

In the preferred embodiment using the keypad proposed in the present invention, as shown in FIG. 2, the alphabets of Korean letters are separately arranged in a predetermined form on 10 numeric keys (0 to 9) and 20 character keys provided on the keypad, respectively. Setting 210 to extract a Hangul Jamo corresponding to a corresponding operation according to the number of times the key is keyed in;

In step 220 of setting an operation method for inputting a character on the keypad, an operation mode is selected to change input modes of numbers, English letters, and Korean consonants using separate function keys when inputting Korean characters. After the step 230, or without the function key to change the input mode without changing the input mode according to the number of keys, the number of the alphabet, English letters, Hangul consonants can be selected to set the operation mode respectively;

The combination of the Hangul alphabets selected by the number of times the user key-in causes specific Hangul characters to be combined.In this case, a button (number button) corresponding to the Hangul alphabets (consonants and vowels) recognized by the user's key-in Or character buttons), and the Hangul characters are combined through the step 240 of allowing the user to easily select the backlight by turning on the backlight.

3 is a basic conceptual view showing a preferred embodiment utilizing the keypad proposed in the present invention.

4 is a diagram illustrating a numeric keypad according to a preferred embodiment of the present invention. Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 and 4.

When the user inputs numbers and characters from the keypad, the alphabetical consonants of Korean characters are properly applied to the numeric keypad by using the 12 numeric keys (0-9) and the function keys (* and #) attached to the numeric keypad. Hangul is combined by varying the consonants expressed according to the number of times that the key is keyed in several times by arranging them. To this end, the buttons on the numeric keypad were printed with a Korean alphabet, numbers and English letters arranged for each key. In the present invention, in addition to arranging 12 numeric buttons on the keypad, 20 buttons (hereinafter, character button keys) are separately arranged in the free space of the keypad, thereby greatly increasing the number of input interface that the user can select from the keypad. As shown in Figure 2 in the numeric keypad used in the general phone there was some free space between the number buttons (numbers 0-9, * and #) and the number buttons. By arranging the character buttons in the free space, the number of buttons that can be used as an input interface on the keypad has been greatly increased, while there is no big problem in using the number buttons mainly used by users. When the user presses the numeric button and the character button, a predetermined signal is applied to the control unit 110 shown in FIG. 1, and the predetermined Hangul alphabets according to the type and number of the buttons keyed in by the user are combined with each other. It can be used as an input signal of Hangul characters in the device (phone, mobile phone and computer terminal, etc.) using the keypad proposed in the present invention.

Figure 5 is a view showing the side of the numeric keypad according to a preferred embodiment of the present invention, the buttons mainly used in the keypad proposed in the present invention is a number button, should not be inconvenient to the user when using the character button and the number button. The keypad proposed in the present invention not only discriminates the size of the numeric buttons and the size of the character buttons as shown in FIG. 3, but also distinguishes the height and height at the position of each button in the keypad, thereby preventing a typo. Reduced the likelihood of occurrence. In particular, as shown in FIG. 4, the controller 110 of FIG. 1 analyzes the type and number of buttons that a user keyes in, and combines one character with a keyin indicating a Korean consonant. In the key-in that represents Korean vowels, if one or more consonants and vowels are combined according to the combination principle of initial, neutral, and final, the user input when Korean syllable cannot be generated is recognized as an operation mistake and automatically corrects the error. This includes the function of displaying to the user through the display unit 130. For example, Hangul is combined as 'Primary + Neutral' or 'Primary + Neutral + Jongsung' based on the combination principle of Hangeul. The keyin corresponding to the unusable consonant button key belongs to this.

6a to 6b show different implementations of the keypad proposed in the present invention, and the Hangul consonants can be arranged in various ways on the key button of the extended keypad, and the key button operation for selecting each key button can be present. Upon approval, a code (Korean vowel) assigned to the corresponding key button is generated.

6A is a diagram illustrating a keyboard of a numeric keypad according to a first preferred embodiment of FIG. 4.

When the user inputs Korean characters through the keypad, the Korean consonants are determined according to the number of times the key consonants printed on the numeric buttons of the keypad are keyed in. For example, in the case of ㄱ / ㄲ of the number 1 button, 'ㄱ' is selected in the first key, and 'ㄲ' is selected in the second key. Hangul vowels are determined by keying in the vowels printed on the character buttons on the keypad.

The 20 character buttons arranged on the keypad can express 19 Korean vowels, including 14 basic vowels of 21 Korean vowels, as one key-in, and the remaining two Korean vowels are the characters that match the combination of the basic vowels of the vowel. It can be recognized as a key-in combination of a button or as two key-in of a specific character button.

In addition to Hangul consonants, the number buttons are printed with numbers or special characters. The selection of numbers / special characters and Hangul consonants arranged on these number buttons can be combined as the number of keys or the combination of function keys and number of keys. For example, in the case of the number 3 button, when the button for selecting the type of character is used as the function key, 'a' and 'ㄲ' are selected as the number of the Korean selection function key and the number of keys of the corresponding number key. If the button for selecting a character type is not used, the number of keys of the corresponding numeric key is selected as 'AB', 'ㄲ', 'D', 'E', 'F', '3'. Table 1 shows the keyin for selecting the Korean consonants shown in Fig. 4, and the vowels have the same arrangement as shown in the figure.

In the above, a double consonant is represented as a plurality of key consonants of the corresponding basic consonant key, and consonant finalism is expressed as a combination of basic consonants constituting the consonant. However, since there is an arrangement of consonant species that can be combined with one numeric key (0), there is a high possibility of a user typos. This can be prevented as a conversion of the key arrangement method.

6B is a diagram illustrating a keyboard of a numeric keypad according to a second preferred embodiment of FIG. 4. The difference from the first embodiment shown in Fig. 6A is that there is a change in the arrangement of consonants arranged in the number buttons. For the use of the function keys (* and #), the function keys (* and #) are not arranged with Korean consonants, so that the function keys (* and # buttons) can be used for other purposes. For example, it can be used as a character selection button and can be used as a selection button of vowels (ㅙ, ㅞ) which can not be expressed in the character buttons, and character selection buttons such as numbers, Korean consonants, and English characters that can be expressed as key keys of the number buttons. It can be used as. In addition, those of ordinary skill in the art can be seen that it can be used as a button for various functions. Table 2 shows the keyin for selecting the Korean alphabet shown in Figure 6b.

TABLE 2

In the above, the double consonants are represented as a plurality of key consonants of the basic consonant key, and the consonants are expressed as a combination of keys of consonant keys to be combined. High frequency consonants can be expressed as a single key-in.

By arranging consonants and non-combinable consonants combined as consonant finalities in one numeric key, the number of keys required to express a specific consonant finality can be reduced. For example, the consonant finality is twice as a key for input of the second consonant, but the consonants arranged separately on the numeric keys (0: ㅍ, 8: ㅇ) where these consonants are arranged In the control unit 110 shown in FIG. 1 as a consonant not used in the final consonant, when a key corresponding to the Korean consonant is input without inputting a Korean vowel after inputting a key corresponding to the final consonant, the consonant final consonant is combined. By judging automatically, the one-time key-in of the numeric keys (0, 8) is recognized as the consonant input of the ㅍ and ㅎ rather than the Korean consonants of the ㅊ and ㅇ respectively.

6C is a diagram illustrating a keyboard of a numeric keypad according to a third preferred embodiment of FIG. 2. The difference from the point shown in Fig. 6b is that the Hangul consonants arranged on the numeric buttons have been changed. Table 3 shows the keyin for selecting the Korean alphabet shown in Figure 6c.

TABLE 3

In the above, the double consonants are represented as a plurality of key consonants of the basic consonant key, and the consonants are expressed as a combination of keys of consonant keys to be combined. High frequency consonants can be expressed as a single key-in. In FIG. 6B, in order to reduce the number of keys required for consonant expression, the control unit 110 may automatically convert the same. In FIG. 6C, the same effect may be obtained by changing the key arrangement of the consonants.

6D is a diagram illustrating a keyboard of a numeric keypad according to a fourth preferred embodiment of FIG. 4. This is because the positions of 'ㅋ' and 'ㄷ' on the numeric keypad of FIG. 6C are changed, and the keyin for selecting the Korean alphabet is shown in Table 4 as a table.

FIG. 7 is a block diagram illustrating a case where a keypad to which the embodiment of FIG. 4 is applied is connected to an existing mobile phone. The keypad proposed in the present invention can be applied to a computer terminal including a telephone and a mobile phone. In this case, the keypad proposed in the invention may be used at the time of production of the mobile phone, but it is a block diagram showing a case where only the parts of the keypad of the mobile phone which is being produced and used are used as a signal which is being used in the model of the mobile phone to be applied. It is the largest difference from the block diagram shown in FIG. Hereinafter, with reference to Figure 7 will be described in detail.

The controller 110 controls the overall operation of the keypad. Memory 120 stores a program for controlling the overall operation of the keypad, and serves to temporarily store the input / output data when the overall operation is performed by the controller 110. The display unit 130 changes a backlight light attached to a button of a keypad according to an operation of a user's key or displays numbers and letters as a signal applied through the controller 110 to a connected LCD. The key input unit 140 is a key part of the present invention and has a function key used for a special purpose and a character key proposed by the present invention, in addition to the numeric keys configured on the existing keypad, and when the user presses a predetermined key through the keypad, The signal is applied to the control unit 110.

The conversion unit 750 converts the signal applied to the control unit 110 by the user through the key input unit 140 from the signal processed by the existing mobile phone, thereby converting the signal to the signal being used in the mobile phone. to be. In the above, the type of signal according to the model of the mobile phone to be converted is based on the data stored in the memory 120, which can be input through the connected interface or the communication function of the mobile phone. The central processing unit 760 interprets a user's input authorized through the conversion unit 750 as a part in charge of signal processing required by the mobile phone, and inputs numbers and letters (Korean alphabet, English letters, and special characters) input by the user. Text, etc.) are expressed through the display unit 770 and the audio unit 780 in the mobile phone.

8 is an embodiment according to the present invention to actively display the keys corresponding to the Hangul consonants vowels that can actively combine the Hangul characters according to the user's Jamo input, as shown in FIG. Informing the user is shown as an example. According to an embodiment of the present invention, it is possible to display the Hangul alphabet that can be combined as Hangul characters in various ways other than the backlight of the key.

When the user inputs a key corresponding to the Hangul consonant 810, the consonant is connected to the two consonants as consonants in the control unit 110 shown in FIG. 1 and the consonant consonant (ㄳ, In step 820, it is determined whether or not the input of the consonant (a, b, c, d, k, k, k) is initially input from m, k, k, k, k, k, k, k). Hangul can be combined as initial + neutral + final or initial + neutral. Therefore, when the consonant input corresponding to the initial input consonant (a, b, c, ㄹ, ㅂ, ㅂ, ㅈ) of the consonant is not a consonant input, it can be combined as a Korean character because it is 'first + neutral'. If the display corresponds to the initial input consonants of the consonant species, the combination may be 'consonant + neutral' or 'single' if it can be combined as a Korean character. And step 840 of all keys corresponding to the vowels to be displayed as backlight lights. In this case, the user inputs a key to determine if the key corresponds to Korean consonants and vowels (850). After the step 870 of displaying the backlight light, if the user's input continues to exist, the process described above is repeated again, if there is no user input is terminated.

As described above, the present invention includes more buttons than the conventional keypad, thus providing a user with more input interface selection. In addition, most Korean consonants, including basic consonants and basic vowels, can be represented by one key-in, thus reducing the number of key-in required for neutral and final consonants and reducing the use of excessive function keys. In addition, it is possible to reduce typos of users as appropriate key placement of Hangul consonants, to improve the speed of simultaneous input of numbers / characters, and to use two hands simultaneously when typing.

Therefore, it is an advantage that Korean characters can be easily and simply expressed with a small number of keys, and can be convenient to the user in many cases where Korean input is required, such as an SMS service and an Internet service of a mobile phone. Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
