Description

Apparatus and method for key input implemented on mobile device}

The present invention relates to a key input device and a method implemented in a portable device, and more particularly, to a device and method for displaying a character on the screen through the pressing operation of the key assigned the minimum unit of the character.

Recently, as the development of portable devices such as mobile phones, PMPs, and PDAs is accelerated, portable devices having a touch display are becoming more common. Such a touch device is not provided with a keypad implemented in hardware, and is usually provided with a touch keypad implemented in software and displayed through a display as necessary. However, the display of a portable device that emphasizes portability is limited in size to a size that can be grasped by a human hand, and thus the size of a keypad displayed on the display is also limited.

Among the touch keypads used in the related art, a key arrangement of a keyboard commonly used may be applied as it is. In this case, since a large number of keys must be arranged in a limited size display, the size of one key is too small, which increases the possibility of error in character input. In addition, when arranging keys that are large enough so that an error does not occur, a large number of consonants or vowels are assigned to one key, and thus the character input speed is slowed as the same key is touched several times to input a desired character. Has its drawbacks.

An object of the present invention is to provide a key input device and a method implemented in a portable device capable of quickly inputting a desired character a minimum number of times while preventing a key from being wrongly pressed during character input.

Another technical problem to be solved by the present invention is to read by a computer recording a program for executing a key input method implemented in a portable device capable of quickly inputting a desired character at a minimum number of times while preventing a key from being wrongly pressed. To provide a recording medium that can be.

In order to achieve the above technical problem, a key input device implemented in a portable device according to the present invention includes a plurality of consonant keys and a plurality of basic vowels, each of which is assigned a plurality of terminal sounds, among the minimum units constituting the Hangul. A character key array consisting of a plurality of vowel keys is stored, wherein a plurality of consonants in the character key array are respectively allocated to the consonant keys to which corresponding terminal sounds are assigned, and a plurality of double vowels are respectively assigned to the vowel keys. part; And when a selection signal corresponding to a key constituting the character key array is input, outputs a minimum unit allocated to a key to which the selection signal is input, on a screen, wherein the selection signal corresponding to the consonant key is greater than or equal to a preset reference time. If it is continued, outputs the letters in which the vowels set in advance are combined with the consonants outputted on the screen by the selection signal, and outputs them on the screen by the selection signal when the selection signal corresponding to the vowel keys lasts more than a preset reference time. And an output unit for outputting a letter in which a consonant is set in advance to the vowel.

In order to achieve the above technical problem, a key input method implemented in a portable device according to the present invention includes a plurality of consonant keys and a plurality of basic vowels, each of which is assigned a plurality of terminal tones among the minimum units constituting the Hangul. The minimum unit is output to the screen based on a character key arrangement composed of a plurality of vowel keys, and in the character key arrangement, a plurality of consonants are respectively assigned to the consonant keys to which a corresponding terminal tone is assigned, and the plurality of double vowels When a selection signal corresponding to a key constituting the character key array is inputted in duplicate to a vowel key, the minimum unit allocated to the key to which the selection signal is input is output to the screen, but the selection signal corresponding to the consonant key is displayed. If is continued for more than a preset reference time to output a character combined with a pre-set vowel to the consonant output on the screen by the selection signal , When the selection signal corresponding to the collection of keys for more than the reference time set in advance and outputs a consonant set in advance to the combining character bar, to be output to the screen by the selection signal.

According to a key input device and method implemented in a portable device according to the present invention, by using a character key array assigned with consonants and vowels to 14 consonant keys and 10 vowel keys, a key is prevented from being pressed incorrectly during character input. At the same time, you can enter characters quickly and accurately with the minimum number of presses without using the shift key like a computer keyboard. In addition, by using a continuous selection signal corresponding to a single consonant key or a vowel key, the preset letters are output so that the frequently used letters can be input quickly. Furthermore, the user's movement distance is shortened by touching a single vowel key twice in succession without having to touch each vowel key to which the two main vowels are respectively assigned to input the composite vowel, thereby improving the character input speed.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of a key input device and method implemented in a portable device according to the present invention.

1 is a view showing the configuration of a preferred embodiment for a key input device implemented in a portable device according to the present invention.

Referring to FIG. 1, the key input device 100 according to the present invention includes a storage unit 110 and an output unit 120, and may be implemented in various devices including a display device. In one embodiment, the key input device 100 according to the present invention is implemented in the smart phone 200 with a touch display as shown in FIG.

However, the device in which the key input device 100 according to the present invention can be implemented is not limited to the smart phone 200, and touches such as kiosks as well as portable small electronic devices such as PDAs requiring text input. It can also be implemented in devices that use display displays. Hereinafter, the configuration and operation of the present invention will be described with a representative embodiment in which the key input device 100 according to the present invention is implemented in the smart phone 200 as shown in FIG. 1.

First, the storage unit 110 stores a character key array 300 including a plurality of consonant keys and a plurality of vowel keys. 2 is a diagram illustrating an embodiment of a character key arrangement 300 including a consonant key and a vowel key.

Referring to FIG. 2, the plurality of consonant keys 310 of the character key array 300 may include a plurality of terminal sounds among the minimum units constituting the Hangul, that is, a 'b', 'b', 'c', 'ㄹ', ' ',', ',' ㅅ ',' ㅇ ',' ㅈ ',' ㅊ ',' ㅋ ',' ㅌ ',' ㄷ 'and' ㅎ 'are assigned respectively, where' ㄱ ',' ㄷ ' ',' ㅂ ',' ㅅ 'and' ㅈ 'each have a corresponding consonant such as' ㄲ', 'ㄸ', 'ㅃ', 'ㅆ' and 'ㅉ'. Accordingly, such consonants are overlapped with the consonant keys 310 to which the corresponding terminal sounds are assigned.

In addition, a plurality of vowel keys 320 include a plurality of basic vowels, namely 'ㅏ', 'ㅑ', 'ㅓ', 'ㅕ', 'ㅗ', 'ㅛ', 'TT', 'ㅠ', 'ㅡ' And '|' are each assigned. Also, the double vowels 'ㅐ', 'ㅒ', 'ㅔ', 'ㅖ', 'ㅘ', 'ㅙ', 'ㅝ', 'ㅞ', 'ㅚ' and 'ㅟ' are the vowels to which the default vowels are assigned. Duplicate assignments are made to the key 320, and the vowel 'ㅢ' is not separately assigned to the vowel key 320, but is displayed on the screen by a combination of 'ㅡ' and 'ㅣ'.

As described above, in the key input device 100 according to the present invention, the character key arrangement 300 stored in the storage unit 110 is composed of 14 consonant keys 310 and 10 vowel keys 320. By using fewer keys than key arrays that use arrays such as, you can prevent you from accidentally pressing a different key than you intended. In addition, since all consonants and vowels can be displayed on the screen with only two touches, characters can be entered at a faster speed than the method of entering characters by the 12 keys used in the mobile phone.

Similarly, the consonant keys and the vowel keys are arranged on a computer keyboard. In the key input device 100 according to the present invention, as shown in FIG. By arranging and arranging the vowel key arrangement made up of the vowel keys 320 on the right side, characters can be input simply and quickly. At this time, the consonant key array may have a 5 × 3 form, and the consonant keys 310 constituting the consonant key array are arranged in each row according to the arrangement order of the Hangul terminal sounds, and the vowel key array of the 5 × 2 type is arranged. In each row, the vowel keys 320 may be arranged according to the arrangement order of the Korean basic collection. As such, by arranging the consonant key 310 and the vowel key 320 according to the order of the Hangul terminal sound and the basic vowel familiar to the user, the user can easily find and input the desired consonant or vowel.

On the other hand, since there are 14 consonant keys 310, the keys located at the point (5,3) in the consonant key array are not assigned terminal sounds, and instead, a letter is input when a character is input, such as a space key of a computer keyboard. The space key 330 for inputting a space of the is disposed at the corresponding position. The location of the blank key 330 may also help to improve the text input speed.

In addition to the consonant key 310 and the vowel key 320 described above, the character key arrangement 300 may further include various function keys for performing additional functions. That is, referring to FIG. 2, five function keys 340 to 380 are disposed on the right side of the vowel key arrangement. These function keys 340 to 380 include a switching key 340 for switching between Korean input mode, numeric input mode, and English input mode from the top, left shift key 350 for moving the cursor to the left on the screen, and cursor on the screen. Right move key 360 for moving the right side, a delete key 370 having the same function as the backspace key (←) of the computer keyboard, and a newline key 380 having the same function as the enter key of the computer keyboard. .

The key input device 100 according to the present invention provides the user with the character key arrangement 300 having the configuration as described above, so that the user has the consonants and the consonants assigned to each of the consonant key 310 and the vowel key 320. Combine vowels so that you can enter the letters you want.

The output unit 120 outputs the character key array 300 stored in the storage unit 110 on the screen, and the user inputs a selection signal corresponding to a desired key by referring to the character key array 300 output on the screen. To help. In this case, when the screen on which the character key array 300 is output is a screen of a touch type display device, a user may touch a point where a desired key is located on the screen to generate a selection signal corresponding to a key on which a touch operation is performed. have.

As another embodiment, when the screen on which the character key array 300 is output is a screen of a general display device and a separate keyboard is not provided, the user may use a device such as a remote controller or a mouse to output a character key array on the screen. By selecting a desired key in 300, a selection signal corresponding to the corresponding key may be generated.

Hereinafter, each of the consonant key 310 and the vowel key 320 is selected based on a selection signal input corresponding to the consonant key 310 and the vowel key 320 constituting the character key array 300 output on the screen. A method of outputting the assigned consonants and vowels on the screen will be described in detail.

First, when the selection signal corresponding to the key constituting the character key array 300 is input, the output unit 120 outputs the minimum unit of Hangul assigned to the key to which the selection signal is input. This is the same as the existing key input method, and the terminal sound and the basic vowel preferentially assigned to each of the consonant key 310 and the vowel key 320 touch the corresponding consonant key 310 and the vowel key 320 briefly once. It can output to the screen by the selection signal which generate | occur | produces by this. In addition, the double consonants allocated to each of the consonant keys 310 may be output on the screen by a selection signal generated by touching the consonant keys 310 twice in succession, and the duplicate consonants assigned to the vowel keys 320 may be output. The double bar may be output on the screen by a selection signal generated by touching the vowel key 320 in succession twice. In addition, when the consonant key 310 and the vowel key 320 are alternately touched, the completed letters may be displayed on the screen by outputting the consonants and the vowels in order by the selection signal generated accordingly.

However, the character input method by the key input device 100 according to the present invention is distinguished from the conventional method by touching only one consonant key 310 or one vowel key 320 to display a completed character screen Can be printed on

Specifically, when the selection signal corresponding to the consonant key 310 lasts for more than a preset reference time, the output unit 120 combines a pre-set vowel to the terminal sound assigned to the consonant key 310 to which the selection signal is input. When the selection signal corresponding to the vowel key 320 continues for a reference time or more, the character outputs a character in which a consonant preset is combined with a basic vowel assigned to the vowel key 320 to which the selection signal is input.

There may be letters with a high frequency of use when entering letters, and these letters of high frequency of use need to be entered quickly through the smallest number of touch operations. Therefore, in the key input device 100 according to the present invention, if a selection signal input corresponding to one consonant key 310 lasts for more than a reference time, a predetermined vowel is combined with a consonant assigned to the corresponding consonant key 310. Make the characters print. For example, if the user continuously touches the point where the consonant key 310 assigned with 'ㄱ' is located in the character key array 300 output on the screen for a reference time or more, the output unit 120 is connected to 'ㄱ'. A 'ga' combined with a preset vowel 'ㅏ' can be displayed on the screen.

As in the case of consonants, in the case of vowels, the output unit 120 outputs the consonants set in advance to the vowels assigned to the vowel keys 320 when the input signal corresponding to one vowel key 320 lasts more than a reference time. This combined character is printed. That is, when the user continuously touches the point where the vowel key 320 assigned with 'ㅏ' is located in the character key array 300 output on the screen for more than a reference time, the output unit 120 may advance to 'ㅏ'. 'A' combined with the set consonant 'ㅇ' is displayed on the screen.

As described above, the user touches only one key so that one letter including the minimum unit of Hangul assigned to the key is automatically displayed on the screen, so that several keys are touched to input frequently used letters. You don't need to do this, which speeds up the text entry.

In addition, the vowels coupled to the consonants assigned to the consonant keys 310 into which the continuous selection signal is input and the consonants coupled to the vowels assigned to the vowel keys 320 into which the continuous selection signal is input are basically 'ㅏ' and 'ㅇ. It may be set to ', and the setting may be changed by the user by providing a user interface. The vowels coupled to the consonants assigned to each consonant key 310 may be set differently. Likewise, the consonants combined to the vowels assigned to each vowel key 320 may also be set differently in consideration of the frequency of use of letters. Can be. For example, vowels combined with 'ㄱ' may be set differently as 'ㅏ', and vowels combined with 'b' may be set differently as 'ㅓ'. Consonants coupled to ㅗ 'may be set differently to' ㅇ '.

In addition, when one long consonant key 310 is touched and one vowel is combined with the consonant assigned to the consonant key 310 and one long vowel key 320 is touched, the corresponding vowel key ( Although only one consonant is combined with the vowel assigned to 320, the present invention is not limited thereto. If one consonant key 310 or the vowel key 320 is touched for a long time, the consonant or vowel assigned to the corresponding key may be changed. The symbols, words or phrases set in advance may be output on the screen.

For example, if the user touches 'ㅇ' for a long time, the preset phrase 'hello' may be displayed on the screen, and if the user touches 'ㅏ' for a long time, the preset sentence 'happy new year' is displayed on the screen. It can also be output to As such, symbols, words, or phrases corresponding to each consonant or vowel may be set and stored in advance, and may be changed by the user by providing a user interface.

Next, an embodiment of a case where a plurality of selection signals corresponding to the plurality of consonant keys 310 are continuously input. That is, after the first consonant is output on the screen in response to the first selection signal corresponding to the consonant key 310 to which the first consonant is allocated, the second consonant is assigned to a second consonant different from the first consonant. In this case, the second selection signals are sequentially input. In this case, the form in which the consonants are output on the screen varies depending on whether the position where the first consonants are output is a consonant or a final consonant in the letter.

First, when the second selection signal is input when the first consonant is output at the position of the first consonant according to the first selection signal, the first consonant is not used in the first consonant of the Korean alphabet because a compound consonant combining two different consonants is not used. Only one of the second consonant and the second consonant may be used. In the conventional character input system, when two different consonants are sequentially input as first consonants, the two consonants are output at separate positions on the screen, and thus the first consonants do not form a complete character. However, in the key input device 100 according to the present invention, the first consonant is output at the initial position, but when the second selection signal for continuously outputting the second consonant on the screen is input, the first consonant is first output on the screen. Convert to second consonant.

For example, when the user sequentially inputs 'ㄱ', 'ㄴ', and 'ㅏ' through the character key array 300 output on the screen, if the existing character input system is used, the form displayed on the screen is It becomes like 'a'. However, in the present invention, since the output unit 120 converts consonants previously output when different consonants are continuously inputted at the initial position, the output consonants 'ㄱ' are converted to 'b' which is output later and displayed on the screen. A letter like 'I' is printed. Therefore, when the user incorrectly inputs the consonant, the user may touch the consonant key 310 to which the consonant originally intended to be input has been modified without using the delete key 370 to substantially modify the letter.

As such, whether to convert the first consonant output at the initial position into the second consonant may be changed by the user's setting. If necessary, a user may want to continuously input only consonants, and in this case, a function of converting a consonant input first into a consonant input later may be unnecessary. Therefore, the user interface may be set to be displayed on the screen when the user continuously touches the plurality of consonant keys 310.

Next, the first consonant output on the screen according to the first selection signal corresponds to the position of the finality in the character. In this case, it is processed in the same manner as the existing character input method. That is, the output form on the screen varies depending on whether there is a compound consonant combining the first consonant and the second consonant.

If the first consonant output on the screen according to the first selection signal and the second consonant corresponding to the second input signal currently input can be combined to form a compound consonant such as 'ㄺ', 'ㅄ' The first consonant 120 outputs a second consonant so that the second consonant is combined with the first consonant outputted to form a compound consonant. That is, the user can input by sequentially touching the consonant keys 310 to which each terminal sound constituting the compound consonants is assigned, in order to input the compound consonants at the final position. For example, if you want to complete the letter by marking 'ㄺ' on Jong-sung, you should use the method to print 'ㄹ' first on the screen and then combine 'ㄱ'. The first selection signal may be generated by touching 310 first, and then the second selection signal may be generated by touching the consonant key 310 to which 'a' is assigned.

However, when the first consonant is output at the final position and there is no compound consonant in which the first consonant and the second consonant are combined, the second selection signal is continuously output after the first consonant is output according to the first selection signal. Even if it is input, the second consonant cannot be combined with the first consonant. Accordingly, in this case, the output unit 120 outputs the first consonant and the second consonant separately on the screen, and the second consonants output later are output at the initial position of the new letter.

On the other hand, as described above, in order to output a pair of consonants that are repeatedly assigned to a few consonant keys 310, if you touch the consonant keys 310 twice at a time interval within a preset reference interval, do. However, even when the first selection signal and the second selection signal corresponding to the same consonant key 310 are continuously input at a time interval larger than the reference interval, two identical signals are considered in consideration of their positions within the letters of the consonant output on the screen. If the consonants cannot be output separately, they are output as double consonants.

For example, when a consonant 'a' is output at a position corresponding to a consonant within a letter, and the user touches the consonant key 310 to which 'a' is assigned after a time corresponding to the reference interval elapses Since the two consecutively output 'b' can only appear as 'ㄲ' at the initial position, the output unit 120 allows the second output 'a' to be sequentially combined with the already output 'a'. .

However, if the letter 'b' previously printed on the screen corresponds to the finality of the character, that is, the position of the bearing, the second 'a' is output to be combined with the first letter 'b' to form a double consonant 'ㄲ'. It can be printed or it can be printed as the first letter of a new letter, separate from the first printed 'ㄱ'. Therefore, the output unit 120 is located at the initial position of the new letter if the second 'a' corresponds to the input selection signal after a time corresponding to the reference interval has elapsed from the time when the first 'a' is output. Print the second 'ㄱ'.

However, if the second 'ㄱ' corresponds to a selection signal input at a time interval within the reference interval, this is a signal to output a double-allocated pair of consonants. Therefore, the first 'AB' is overlapped with the corresponding consonant key 310. Converts to the assigned double consonant 'ㄲ'. At this time, if the converted double consonant 'ㄲ' does not exist at the position of 'ㄱ' before the conversion, that is, the letter included as the finality, the converted double consonant 'ㄲ' is outputted so as to be at the initial position of the new letter. .

As described above, when the same consonant key is touched twice in succession, the form displayed on the screen may vary depending on whether two touches are made within a reference interval. However, due to the user's mistakes, the standard intervals may not be properly maintained, and incorrect characters may be output. Therefore, the key input device 100 according to the present invention may be provided with a function of automatically correcting a letter that is incorrectly output to a letter suitable for the intention of the original user.

For example, in order for the word 'near' to be displayed on the screen, when the second letter 'ca' is inputted, the consonant key 310 assigned with 'ㄱ' is quickly moved to a time interval within the reference interval. You have to touch it twice, otherwise it will be outputted as 'gagai'. In addition, when the word 'school' is printed on the screen, in order to input the finality of 'hak' and 'ca', the first consonant of 'school', the consonant key 310 assigned with 'a' is a reference interval. You must touch twice at longer time intervals. Otherwise, the word 'hahaha' is displayed on the screen unlike the user's intention.

As such, when a user does not keep the standard interval and a character different from the one intended on the screen is output, it is inconvenient to delete the characters already displayed on the screen by using the delete key 370 and newly input the characters. To compensate for this, the output unit 120 may have a function of automatically correcting an incorrectly output letter by grasping a user's intention.

In detail, a plurality of selection signals including a first selection signal and a second selection signal sequentially input in correspondence to the same consonant key 310 to which the double consonants are repeatedly assigned are sequentially input and then the character key arrangement ( In 300, a signal corresponding to a key other than the consonant key 310 and the vowel key 320 is input, and consonants and vowels sequentially output on the screen according to a plurality of selection signals do not form a complete word. When the input time intervals of the selection signal and the second selection signal are changed to form a complete word, the output unit 120 receives a signal corresponding to a key other than the consonant key 310 and the vowel key 320. The consonants and vowels displayed on the screen at the time point are converted into complete words and output.

For example, selection signals corresponding to keys to which 'ㅎ', 'ㅏ', 'ㄱ', 'ㄱ' and 'ㅛ' are assigned by the user's input are sequentially input and successively enter the blank key 330. When the corresponding signal is input, the output unit 120 is a blank key 330 when two 'ㄱ' is input at a time interval within a reference interval and is output as a wrong word such as 'ha'. At the time when the signal corresponding to is inputted, 'ha' which is incorrectly displayed on the screen is converted to 'school', which is a correct form of word output when two 'a' are input at a time interval longer than the reference interval.

Since this input error occurs when the same consonant key 310 with double consonants is repeatedly assigned twice, in this case, an example of an incorrectly printed letter is built in a database in advance and an incorrectly printed letter is generated. It can be fixed automatically. In addition, after constructing a word database based on Korean dictionary data, the combination of consonants and vowels displayed on the current screen does not exist in the word database, but if the combination of consonants and vowels is changed, the words included in the word database are matched. In this case, you can also use the method of correcting misprinted words.

3 is a flowchart illustrating a process of performing a preferred embodiment when a selection signal corresponding to two consonant keys 310 to which different consonants are assigned is continuously input.

Referring to FIG. 3, first, when a selection signal corresponding to a consonant key 310 to which a first consonant is assigned is input (S310), when the selection signal is longer than a preset reference time ( S320) Outputs the letters in which the vowels set in advance to the first consonant are combined (S330), and outputs the first consonants on the screen when the selection signal lasts for a shorter time than the reference time (S340).

As such, when the first consonant is output on the screen, a selection signal corresponding to the consonant key 310 assigned with a second consonant different from the first consonant is input (S350), and the position of the first consonant is formed in the first letter. If it corresponds to (S360), the output unit 120 converts the first consonant output first to the second consonant (S370).

In addition, when the position of the first consonant corresponds to the finality and there is a consonant in which the second consonant is coupled to the first consonant (S380), the output unit 120 sequentially outputs the second consonant to the first consonant output on the screen. The second consonant outputs to be combined to form a compound consonant (S400). If there is no consonant in which the second consonant is coupled to the first consonant, the second consonant is output separately from the first consonant (S390).

Next, an embodiment relating to a case where a plurality of selection signals corresponding to the vowel key 320 are continuously input will be described. Since the double vowel is assigned to each vowel key 320 as described above, when a specific double vowel is to be displayed on the screen, the double vowel is repeatedly assigned twice by touching the vowel key 320 to which the double vowel is duplicated. Can be printed on the screen.

However, double vowels can also be formed by a combination of two basic vowels. For example, in the case of the double vowel 'ㅐ', the 'ㅏ' is repeatedly assigned to the vowel key 320 to which the 'ㅏ' is assigned, and the user may touch the 'ㅏ' twice in succession to output it to the screen. It can also be formed by a combination of 'and' | ', so the output unit 120 inputs a selection signal corresponding to the vowel key 320 assigned with' ㅏ 'and the vowel key 320 assigned to' ㅣ 'in order. You can print '화면' on the screen. That is, the output unit 120 first outputs 'ㅏ' on the screen, and when a selection signal corresponding to the vowel key 320 to which 'ㅣ' is continuously assigned is input, the output unit 'ㅏ' is first outputted to 'ㅐ'. Convert to

However, a double vowel can be formed by a combination, such as when the selection signal corresponding to the vowel key 320 to which the 'ㅛ' is continuously input is output after 'ㅏ' is output on the screen according to the input signal. When a selection signal corresponding to two missing vowel keys 320 is sequentially input, the basic vowels outputted first cannot be converted into double vowels. In this case, according to the conventional character input method, 'ㅛ' corresponding to the second input signal is output on the screen as a separate letter not including a consonant. The user must delete the wrongly inputted collection from the screen using the delete key 370 and input the desired collection again.

In the output unit 120 of the key input device 100 according to the present invention, a selection signal corresponding to two vowel keys 320 to which a first vowel and a second vowel cannot be formed is continuous. When the input is performed, the first vowel output on the screen is first converted into a second vowel. That is, in the above case, if the selection signal corresponding to the vowel key 320 to which 'ㅏ' is continuously assigned after 'ㅏ' is output on the screen is input, the output unit 120 outputs 'ㅏ' on the screen. Delete and print 'ㅛ' to convert '결과' to 'ㅛ'.

The same is true if the vowel displayed on the screen is a double vowel. That is, when 'ㅏ' and 'ㅣ' are sequentially outputted and the vowel output on the current screen is a double vowel 'ㅐ', when a selection signal corresponding to the vowel key 320 assigned with 'ㅓ' consecutively is input, Since 'ㅓ' is combined with 'ㅐ' to form a double vowel, the output unit converts 'ㅐ' displayed on the screen to 'ㅓ'.

As described above, when a plurality of selection signals corresponding to the vowel keys 320 are continuously input, when a double vowel cannot be formed, the vowels that are output are converted first. By using), you can get the effect of actually modifying letters by touching the vowel key 320 to which the vowel was originally inputted, without having to delete the vowel already displayed on the screen. Can be.

4 is a flowchart illustrating a process of performing a preferred embodiment when a plurality of selection signals corresponding to the vowel key 320 are continuously input.

Referring to FIG. 4, first, when a selection signal corresponding to the vowel key 320 to which the first vowel is assigned is input (S410), the output unit 120 receives the input selection signal for more than a reference time (S420). In step S430, the first consonant is combined with a preset consonant, and the first consonant is output on the screen when the selection signal is briefly maintained within a reference time (S440). Next, when a selection signal corresponding to the vowel key 320 to which the second vowel is assigned is input (S450), a double vowel can be formed by combining the first vowel and the second vowel (S460). The outputted first vowel is converted into a double vowel formed by combining the first vowel with the second vowel (S470), and if there is no double vowel, the first vowel output on the screen is converted to the second vowel (S480). ).

Furthermore, a function of outputting a symbol or number on a screen may be implemented through a key selected from the plurality of consonant keys 310 and the vowel keys 320.
