TECHNICAL FIELD The present invention relates to character input control, and more particularly, to a phonetic character input technique.

When a large number of software or hardware key buttons are used in a device having a limited size such as a cellular phone, operation may be inconvenient. For example, assuming you have implemented a 3 x 4 hardware key button on a very small mobile phone, manipulation may be inconvenient due to the size of the user's finger.

For example, if a 3x4 software key button is implemented in a very small area on a touch screen screen of a mobile phone, the size of the key button may be very small and the operation may be inconvenient.

Accordingly, the present inventor has been studying a technique that can input characters using a smaller number of key buttons in a device having a limited size such as a cellular phone, thereby improving user convenience.

The present invention provides a character input technique capable of inputting characters using a smaller number of key buttons in a device having a limited size such as a mobile phone.

It is possible to input phonetic characters so that characters can be completed with only a few user operations.

According to an aspect of the present invention, there is provided a method for displaying a small number of basic key words for initial, neutral, and last characters in a character input in a character system consisting of a prefix, a neutral, and a longitudinal character such as Hangeul, To enter the initial, neutral, and last names.

According to a further aspect of the present invention, a phonetic alphabetic character plate is used as the derivative keyboard.

In a device having a limited size such as a cellular phone, characters can be input using a smaller number of key buttons, thereby improving user convenience.

Since phonetic completion type characters can be input, characters can be completed by only a small number of user operations, thereby improving the character input speed.

In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Prior to describing the embodiments of the present invention, terms used throughout the specification are defined. These terms are defined in consideration of the functions of the embodiments of the present invention. Therefore, the definitions of these terms should be based on the contents throughout the specification will be.

1 is a schematic diagram of a character input device according to the present invention. As shown in the figure, the character input apparatus 100 according to this embodiment includes a preliminary input unit 110 for inputting preliminary input, a neutral input unit 120 for inputting neutral, a longitudinal input unit 130 for inputting the longitudinal, .

When the character input apparatus 100 enters a character input mode such as a text message transmission using a mobile phone or the like, the character input apparatus 100 transmits the first character through the first character input unit 110, the neutral character through the neutral character input unit 120, (130), the character is completed and the characters are completed.

The character input device 100 according to this embodiment can be used for inputting characters by using a smaller number of key buttons in a device having a limited size such as a mobile phone, It has a 2-input system and receives letters as a phonetic completion type.

FIG. 2 is a block diagram of a preliminary input unit of a character input device according to an embodiment of the present invention. Referring to FIG. The initialization input unit 110 according to this embodiment includes a basic chessboard display unit 111, a basic chessness selection unit 112, a derivative chessboard display unit 113, and a derivative chess selection unit 114.

The basic preprojection plate display unit 111 displays the basic prosouter plate. For example, in a device having a limited size such as a cellular phone, a basic chessboard having consonants arranged in 3x2 as shown in Fig. 3 may be employed in order to allow characters to be input using a smaller number of key buttons.

Referring to FIG. 3, 'a', 'd', 'd', and 'd' are arranged in the upper part of the basic chessboard, 'k' It can be seen that 'o' is placed. The number of key buttons is smaller than that of a conventional 3 × 4 keyboard installed in a mobile phone or the like.

The basic chipless selection unit 112 selects one basic chipless in the basic chessboard displayed by the basic chessboard display unit 111. For example, the basic chorus selection unit 112 may select a basic chorus by detecting the depression or depression of any one of the basic choruses displayed on the basic chorus plate.

The derivative display device 113 displays the derivation lead character plate interlocked with the basic lead character selected by the basic lead character selecting unit 112. [ For example, as shown in Fig. 4, it is possible to employ derivatized precessional keyboards interlocked with the basic prefixes arranged in the basic preliminary keypad.

Referring to FIG. 4, 'a', 'k', and 'ㄲ' are arranged in a derivative primitive in the derived primitive keyboard interlocked with the primitive primitive 'a'. In the derived primitive keyboard interlocked with the primitive primitive ' ',' '', '' ','. ', And' ㄸ 'are arranged as derivative primitives.

On the other hand, '' 'is arranged as a derivation primitive in the derivative primitive keyboard linked to the basic primitive' '', and 'ㅁ', 'ㅂ', '虚', '' ' 'Is placed as a derivative primitive.

On the other hand, the derivation key board which is interlocked with the basic primordial 'ㅅ' is arranged as a derivative primordial to 'ㅅ', 'ㅈ', '' ',' ㅆ ',' ㅉ ' It can be seen that 'ㅇ' and 'ㅎ' are arranged in a derived form in the keyboard.

In Fig. 4, phonetic completion derivation primitives such as 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', and 'ㅉ' that can not be seen in a combination 3 × 4 array keyboard in a mobile phone can be seen. In a conventional combination keypad of 3 × 4 array in a cellular phone or the like, for example, in order to input 'ㄲ', 'a' has to be pressed twice, but in this embodiment, 'ㄲ' is pressed only once.

On the other hand, in FIG. 4, in the case of 'c', it can be seen that a plurality thereof are arranged on the derived key board. This makes it possible to increase the convenience of users by inputting the breakpoints even if multiple breakpoints are selected at the time of inputting the breakpoints.

In FIG. 4, the derivative primitive keyboard 113 is arranged such that the derivation primitive is the same as the primitive primitive in the same position as that of the basic primitive primitive selected in the primitive selecting unit 112 It can be seen that it is displayed.

For example, referring to FIG. 3, in the basic chessboard displayed by the basic chessboard keyboard display unit 111, 'g' is located in row 2 and column 2, and the user selects 'g' as the basic chessboard, Is also located in row 2 and column 2. So, when the user wants to enter 'g', press the key button located in row 2 and column 2 twice in succession.

In other words, if the derivative primitive selected last in the primality is the same as the primitive primitive, the primitive primitive is selected by pressing twice the same position, or the derived primitive is selected after a certain time after the primitive primitive is pressed, It is possible to improve convenience of use.

On the other hand, as shown in Fig. 4, in the transverse direction of the derivative key board, consonants derived by adding strokes to consonants corresponding to the basic prefix are arranged, and in the longitudinal direction, ) Of the consonants may be arranged.

In FIG. 4, it can be seen that the derived consonant 'c' is arranged by adding one stroke in the transverse direction of 'b' in the derived initial keyboard for basic primitive 'b'. In Fig. 4, it can be seen that a strong sound 'ㅋ' is arranged in the longitudinal direction of 'a' in the derived initial keyboard for the basic beginning 'a'.

On the other hand, as shown in FIG. 4, consonants corresponding to the consonants of the consonants in the transverse direction may be arranged in the diagonal direction of the derivative key board. In Fig. 4, it can be seen that the diagonal line 'ㄲ' is arranged in the diagonal direction of 'a' in the derived initial keyboard for basic primitive 'a'.

The derivative primitive selection unit 114 selects one derivative primitive from the derivative primitive character plate that is displayed by the derivative primitive character plate display unit 113. For example, when the derivative primitive keypad display unit 113 detects the depression of one basic primitive in the basic primitive selection unit 112 and displays the derived primitive keypad linked with the selected basic primitive, If the derivation primitive selection unit 114 is configured to select a derivation primitive of a position where the derivative primitive selection unit 114 detects the pulled-out after dragging on the derivation primitive keyboard displayed by the derivative primitive character display unit 113, It is possible to input the leading character in the manner described above.

Alternatively, when detecting the touch (press and release) of one of the basic primitives in the basic primitive selection unit 112, the derivative primitive character plate display unit 113 displays the derived primitive character plate And the derivation initial selection unit 114 detects any one of derivative touches (pressed and separated) on the derivative leaded keyboard displayed by the derivative leaded keyboard display unit 113 If you implement it by selecting a derived primitive, you can enter the primitive in a double-touch manner.

Accordingly, the present invention has a binary input system that is binarized by the above-described implementation, and it is possible to input a beginning character by a phoneme completion type, so that a device having a limited size such as a mobile phone can input a beginning character by using a smaller number of key buttons .

5 is a block diagram of a neutral input unit of a character input apparatus according to an embodiment of the present invention. The neutrality input unit 120 according to this embodiment includes a basic neutron plate display unit 121, a basic neutrality selection unit 122, a derived neutron plate display unit 123, and a derived neutrality selection unit 124.

The basic neutron plate display part 121 displays the basic neutron plate. For example, a basic neutron plate having consecutive 3 × 2 consonants as shown in FIG. 6 may be employed in order to allow characters to be input using a smaller number of key buttons in a device having a limited size such as a cellular phone.

Referring to FIG. 6, the upper part of the basic neutron plate is arranged with a neutral vowel, a positive vowel, and a negative vowel, and the lower vowels vowel, vowel, Can be seen. The number of key buttons is smaller than that of a conventional 3 × 4 keyboard installed in a mobile phone or the like.

The basic neutron selection unit 122 selects one basic neutrality from the basic neutron plate displayed by the basic neutron plate display unit 121. For example, when the basic neutrality selection unit 122 senses that one of the basic neutrals on the basic neutron plate displayed by the basic neutron plate display unit 121 is pressed or released, Neutral can be chosen.

The derived neutron plate display unit 123 displays the derived neutron plate interlocked with the selected neutral neutron selected by the basic neutron selector 122. For example, as shown in Fig. 7, it is possible to employ derived neutron plates interlocked with the basic neutrals arranged on the basic neutron plate.

Referring to FIG. 7, 'ㅣ', 'a', 'ㅓ', 'ㅢ', 'ㅑ', and 'ㅕ' are arranged in a derivative neutrality in the derived neutron plate interlocked with the basic neutrality ' It can be seen that 'ㅐ', 'a', 'ㅘ', 'ㅒ', 'ㅑ', and 'ㅙ' are arranged in a derivative neutrality in the derived neutron plate interlocked with the neutral 'a'.

On the other hand, the derived neutron plates interlocked with the basic neutrals 'ㅗ' are assigned neutrals with 'ㅙ', 'ㅚ', 'ㅗ', 'ㅘ', 'ㅛ' It can be seen that 'ㅢ', 'ㅛ', 'ㅠ', 'ㅡ', 'ㅗ', 'ㅜ'

On the other hand, 'ㅖ', 'ㅕ', 'ㅞ', 'ㅔ', 'ㅓ', and 'ㅝ' are arranged in the derivative neutrality in the derived neutron sheet interlocked with the basic neutrality 'ㅓ' It can be seen that 'ㅝ', 'ㅠ', 'ㅞ', 'ㅟ' and 'ㅜ' are arranged in a derived neutral form in the interfering derived neutron plate.

In a conventional combination keypad of 3 × 4 array in a mobile phone or the like, for example, 'ㅡ', 'ㅣ', '.' 7 shows a case in which a neutral vowel is displayed by a combination of two letters. In FIG. 7, 'ㅗ', '' ',' ㅢ ',' ㅛ ',' ㅠ ' , 'ㅘ', 'ㅞ', 'ㅔ', 'ㅝ', '' ',' ㅘ ',' ㅘ ',' ㅘ ' ㅟ ', and so on.

For example, in a conventional 3 × 4 array combination keyboard in a mobile phone or the like, 'ㅣ' and '.' Are input to input 'a', and 'ㅣ' and '. &Quot;, but in the case of this embodiment, the neutral is selected by pressing only once.

On the other hand, in FIG. 7, it can be seen that a plurality of neutral neutrals are arranged on the derived neutron plates. This makes it possible to increase the convenience of users by inputting the derivative neutrality regardless of which of the derivative neutrals arranged on the plurality of derived neutron plates is selected at the time of the derived neutrality input.

For example, 'ㅛ' is a derivative neutrality that is interlocked in the basic neutrality 'ㅡ' or interlocked in the basic neutrality 'ㅗ'. On the other hand, 'ㅘ' is interlocked with the basic neutrality 'a', or derived neutrality interlocked with the basic neutrality 'ㅗ'.

In FIG. 7, the derived neutron plate display part 123 is positioned at the same position as the position of the basic neutron plate selected by the basic neutron selector 122, It can be seen that the derived neutron plate is marked to have a derivative neutrality.

For example, as shown in FIG. 6, 't' in the basic neutron plate displayed by the basic neutron plate display unit 121 is located in the third row and the second column. As shown in FIG. 7, the basic neutron plate ' The position of 'ㅜ' is also located on the third row and the second column on the keypad of the derivative collection linked to.

In other words, if the net neutrality that is finally selected is the same as the basic neutrality, then the same position is touched twice (ie, after pressing and releasing) to select the derivative neutrality, So that the input position can be prevented from being changed, thereby improving convenience of use.

On the other hand, as shown in Fig. 7, the derivative neutron plates are arranged in the longitudinal direction with j-system vowels ('ㅑ', 'ㅕ', 'ㅛ', '' ',' ㅒ ',' ㅖ ' In the vertical direction, a w-based vowel ('ㅘ', 'ㅚ', 'ㅙ', 'ㅝ', 'ㅞ', 'ㅟ', 'ㅝ', 'ㅞ' In Fig. 7, in the derived neutron plate interlocked with the basic neutrality 'ㅓ', 'ㅕ' and 'ㅖ' in the longitudinal direction are arranged in the vertical direction, and 'ㅞ' and 'ㅝ' can see.

The derivative neutral selection unit 124 selects one of the derivatives neutrality from the derived neutron plate displayed by the derivative neutron plate display unit 123. [ For example, the derivative neutron plate display unit 123 may be configured to display one of the basic neutrality pressures detected by the basic neutrality selection unit 122 and simultaneously display a derived neutron plate interlocked with the corresponding base neutrality, If the neutrality selecting unit 124 is selected so as to select the derivative neutrality of the removed position by detecting the drag-and-release on the derived neutron plate displayed by the derived neutron plate display unit 123, .

Alternatively, when the basic neutrality selecting unit 122 senses a touch (pushing and releasing) of any one of the basic neutrals, the derived neutron plate display unit 123 displays the derived neutron plate And the derivative neutral selection unit 124 selects a derivative neutrality by sensing any one of the derivative neutral taps on the derivative neutron plate displayed by the derivative neutron plate display unit 123 If you implement it to receive, you will be able to enter neutrality in a double-touch manner.

Thus, by implementing such a structure, it is possible to input the neutrality using a smaller number of key buttons in a device having a limited size such as a mobile phone because it has a binarized neutral input system and can input neutrality with a phoneme completion type .

8 is a block diagram according to an embodiment of the longitudinal input unit of the character input apparatus according to the present invention. The longitudinal input unit 130 according to this embodiment includes a basic longitudinal character plate display unit 131, a basic longitudinal character selecting unit 132, a derived longitudinal character display unit 133, and a derivative character selecting unit 134. [

The basic longitudinal character display section 131 displays the basic longitudinal character display. For example, in a device having a limited size such as a mobile phone, a basic longitudinal key board in which consonants are arranged in 3x2 as shown in FIG. 9 can be adopted in order to allow characters to be input using a smaller number of key buttons.

Referring to FIG. 9, 'a', 'd', 'd', and 'd', which are upper and lower tones, are arranged in the upper part of the basic temporal keyboard, It can be seen that 'o' is placed. The number of key buttons is smaller than that of a conventional 3 × 4 keyboard installed in a mobile phone or the like.

The basic longitudinal character selecting unit 132 selects one basic longitudinal character from the basic longitudinal character plate to be displayed by the basic longitudinal character display unit 131. [ For example, the basic longitudinal selecting unit 132 may select a basic longitudinal by detecting that the basic longitudinal is displayed on the basic longitudinal depending on whether the basic longitudinal is depressed or depressed.

The derivative longitudinal keypad display unit 133 displays and displays the derived longitudinal keyboard interlocked with the basic longitudinal selected by the basic longitudinal selector 132. [ For example, as shown in Fig. 10, it is possible to adopt a derivation-trapezoidal keyboard that is interlocked with the basic longitudinally arranged keyboards.

Referring to FIG. 10, it is shown that a derivative that is interlocked with the basic longitudinal 'a', 'a', 'k', 'ㄲ', and ' It can be seen that 'ㄴ', '' ',' ㅌ ',' ㄸ ',' ㄵ ', and' ㄶ '

On the other hand, '' ',' ㄺ ',' ㄻ ',' ㄼ ',' ㄽ ',' ㄾ ',' ㄿ ', and' ㅀ ' And 'ㅁ', '' ',' ㅃ ', and' ㅄ 'are arranged in a derived form in the derived consonant keyboard that is linked to the basic consonant' ㅁ '. Exceptionally, when 'ㄾ', 'ㄿ' and 'ㅀ' are selected in the drawing, a second derivative consonant plate having a second disturbance of 'ㄾ', 'ㄿ' and 'ㅀ' is displayed, As shown in FIG.

On the other hand, the derivation consonant keyboards interlocked with the basic consonant 'ㅅ' are arranged in the form of 'ㅅ', 'ㅈ', '' ',' ㅆ 'and' ㅉ ' It can be seen that 'ㅇ' and 'ㅎ' are arranged in a derived form on the keyboard.

In FIG. 10, 'ㄲ', 'ㄳ', 'ㄸ', 'ㄵ', 'ㄶ', 'ㄺ', 'ㄻ', and 'ㄼ', which can not be seen in a combination 3 × 4 array keyboard, , 'ㄽ', 'ㄾ', 'ㄿ', 'ㅀ', 'ㅃ', 'ㅄ', 'ㅆ', 'ㅉ' and so on. In a conventional combination keypad of 3 × 4 array in a cellular phone or the like, for example, in order to input 'ㄲ', 'a' has to be pressed twice, but in this embodiment, 'ㄲ' is pressed only once.

On the other hand, in FIG. 10, it can be seen that in the case of 'I' and so on, a plurality of them are arranged on the key board. This makes it possible to increase the convenience of the user by inputting the derivative term regardless of whether the plurality of derivative forms are selected at the time of inputting the derivative term.

In FIG. 10, the derivation longitudinal character plate display unit 133 displays a derivative longitudinal character such that the same generic term as the basic longitudinal character is located at the same position as the position on the basic longitudinal character plate of the basic longitudinal character selected in the basic longitudinal character selecting unit 132 It can be seen that the display processing is performed.

In other words, if the last selected continuity is the same as the basic continuity, the same position is touched twice (by pressing and releasing) to select the derivative term, or after a certain period of time after the basic end touch, So that the input position is not changed so that the user's convenience can be improved.

The derivative term selecting unit 134 selects one of the derivative term in the derivative termination board displayed by the derivative termination board display unit 133. For example, when the depression of one basic depression is detected in the basic depression selecting unit 132, the derivative depressed keypad display unit 133 realizes display processing of the depression peripheral keyboard interlocked with the basic depression, If the longitudinal selector 134 is configured to receive the selection of the trailing edge of the tear off position by detecting drag and drop on the derived trailing edge keyboard displayed by the derivative trailing edge keyboard display unit 133, .

Alternatively, when sensing the touch (press and release) of any basic substep in the basic vertex selection unit 132, the derivation longitudinal keypad display unit 133 may display the derivative elongated keypad So that the derivative term selecting unit 134 selects a derivation termination by sensing a touch of a derivative term on the derivative termination board displayed by the derivative termination board display unit 133 Once implemented, you can enter the last name with two touches.

Thus, by implementing such a configuration, it is possible to input a longitudinal character by using a binary inputting system and inputting a longitudinal character with a phonetic completion type, so that it is possible to input a longitudinal character using a smaller number of key buttons in a device having a limited size such as a mobile phone .

According to an additional aspect, the character input device 100 may further include a character input skip unit 140. [ The character input skip unit 140 senses a skip event and generates a skip event by the skip event input unit 110 or a neutral input by the neutral input unit 120 or a skip event by the event input unit 130 ) Is skipped.

In other words, in this embodiment, when a skip event occurs, a neutral event is not performed and a neutral input is performed. When a skip event occurs, a neutral event and a negative event are not performed. Or if a skip event occurs during the ending input, the input of the next syllable is performed without performing the neutral input. With this implementation, it becomes possible to input emoticons such as 'ㅋㅋ', 'ㅠㅠ', and so on.

At this time, the skip event is generated when the initial input by the initial input unit 110, the neutral input by the neutral input unit 120, or the last input by the contour input unit 130, . For example, if the neutral basic keyboard is displayed by inputting the prefix 'ㅋ', if the neutral is not inputted for a predetermined time, the input of the neutral and ending is skipped, the syllable of 'ㅋ' is completed, . Thus, if you repeat this same input twice, 'ㅋㅋ' can be entered.

Alternatively, during the initial input by the derivative selection unit 114 or the neutral input by the derivative neutral selection unit 124 or the longitudinal input by the derivative selection unit 134, The skip event may be generated. For example, if you select the default prefix 'o', you will see a derivative key 'o', two 'hot' key buttons, and three empty key buttons. At this time, three blank key buttons are key buttons for which no characters are arranged. For example, if the basic primitive selection unit 112 'o' is input and the derivation primitive selection unit 114 selects a key button other than 'o' and 'heh', the primitive input is skipped and advanced to the neutral input step. If the user inputs 't' in the neutral input, 'o' is input in the basic ending selection unit 132, and a key button other than 'o' and 'heh' is selected in the derivation end selection unit 134, the ending input is skipped . Thus, a syllable without a syllable and a syllable 'ㅠ' is completed.

Alternatively, the skip event may be generated by the initial input by the initial input unit 110, the neutral input by the neutral input unit 120, or the longitudinal input by the contour input unit 130, As shown in Fig. For example, if a neutral basic keyboard is displayed by inputting a prefix 'ㅋ', a neutral input is skipped when an area other than the neutral basic keyboard area is touched. If the user inputs an ending 'ㅋ' in this state, .

Alternatively, the skip event may be generated by clicking a specific key button after inputting a preliminary result by the preliminary input unit 110, a neutral input by the neutral input unit 120, or a longitudinal input by the longitudinal input unit 130 have. For example, if you enter a prefix 'ㅋ' to display a neutral basic keyboard and then click a specific key button that is preset to skip the character input, the neutral input is skipped, and if you enter the ending 'ㅋ' Can be input.

According to an additional aspect, the basic initial value selecting unit 112, the derivative primary selecting unit 114, the basic neutral selecting unit 122, the derived neutral selecting unit 124, the basic longitudinal selecting unit 132, The portions 134 may be implemented in the same or different physical or logical devices. The basic neutron plate display section 111, the derived chronological plate display section 113, the basic neutron plate display section 121, the derived neutron plate display section 123, the basic neutron keyboard display section 131, ) May be implemented in the same or different physical or logical devices.

According to an additional aspect of the present invention, there is provided a computer program for causing a computer to function as a computer-readable storage medium storing a computer program for causing a computer to function as: Each of the longitudinal character keyboard display units 133 may be implemented to display the basic chessboard, derivative chessboard, basic neutron chessboard, derived chessboard, basic chessboard and derivative chessboard on the touch screen.

That is, in this embodiment, as shown in Fig. 11, on the touch screen of a device having a limited size such as a cellular phone, a basic superhard plate, a derived superhard plate, a basic neutron plate, a derived neutron plate, Is implemented in software. The user can select a desired character from a basic chessboard, a derived chessboard, a basic neutron chessboard, a derived neutron chessboard, a basic chessboard chessboard, and a derivative chessboard displayed on a touch screen.

According to an additional aspect of the present invention, there is provided a computer program for causing a computer to function as a computer-readable storage medium storing a computer program for causing a computer to function as: Each of the longitudinal keypad display units 133 is provided with a plurality of key buttons each having a basic chorus, a derivative chorus, a basic chorus, a derivative chorus, a derivative chorus, a basic chorus and a derivative chorus to display a basic chorus keyboard, a derived chorus keyboard, Plate, a basic longitudinal key board, and a derivative longitudinal key board.

That is, as shown in FIG. 12, this embodiment is characterized in that hardware key buttons embodied in a device having a limited size such as a cellular phone or the like include a basic key board, a derived key board, a basic neutron board, a derived neutron board, , And a derivative consonant keyboard is displayed. The user can input a character by pressing a key button displayed on the key button.

In order to display a basic key board, a derived key board, a basic neutron plate, a derived neutron plate, a basic key plate and a derivative key plate on hardware key buttons implemented in a device having a limited size such as a cellular phone, A plurality of key buttons 200 are formed on the upper part and a phonetic alphabetic character or a phonetic alphabetic character included in the basic phonetic alphabetic character plate or a derivative phonetic alphabetic character plate, The key buttons 200 should be designed such that the key buttons 200 project the phonetic letters output from the display unit 300 so that the user can recognize the keys.

The character input operation of the character input device according to the above-described embodiment will be briefly described with reference to FIG. FIG. 13 is a flowchart illustrating a character input operation of the character input device according to an embodiment of the present invention.

When entering a character input mode such as transmitting a text message by using a mobile phone or the like, the procedure for inputting a prefix proceeds. First, the character input device displays a basic chessboard in a basic chessboard display step (S110).

The user selects one of the basic chonals in the basic chonnamic keyboard displayed in the basic chonnamer panel display step (S110), so that the character input device selects the corresponding basic chonon in the basic chonster selection step (S120).

If the basic chief stage is selected by the basic chief stage selection step S 120, the character input device displays a derivative chief key plate in which the phonetic completion type consonants interlocked with the basic chief stage selected in the derivative chief key character display step S 130 are arranged.

If a skip event (Skip Event) does not occur in the state in which the basic chorus is selected, it enters the derived choreographic input procedure and skips the chorus input procedure when a skip event occurs.

The user selects one of the derivation primitives from the derivative primitive character plate displayed in the derivative primitive character plate display step S130, and the character input device selects the corresponding derivative primitive in the derivation primitive selection step S140, thereby inputting the primality .

If a skip event occurs in the basic chronological selection step S120 or the derivative chronological selection step S140, the system enters the neutral input procedure without generating a chopping event. In the derivative chronological selection step S140, a skip event is not generated When the derivative primitive is input, the primitive input is completed and the neutral input procedure is entered.

In the neutral input procedure, the character input device displays the basic neutron plate in the basic neutron plate display step (S210).

The user selects one of the basic neutrals in the basic neutron plate displayed in the basic neutron plate display step S210, so that the character input device selects the basic neutrality in the basic neutrality selecting step S220.

If a skip event does not occur in the state where the derivative neutral is selected, a derivation neutral input procedure is entered. If a skip event is generated in the basic midline board selection step S220, Enter the input procedure.

If the basic neutrality is selected by the basic neutrality selection step S220, the character input device displays a derived neutron plate in which a phonemic vowel linked to the basic neutrality selected in the derived neutron plate display step S230 is arranged.

In the derivative neutron plate displayed in the derived neutron plate display step S230, the user selects one of the derived neutrals, and the character input device inputs the neutrality by selecting the corresponding derived neutrality in the derived neutral selection step S240 .

If a skip event does not occur in the state where the derivative neutral is selected, if the skip event is generated, the syllable is completed only in the selected chord in step S140, and enters the input procedure for the next syllable do.

The character input device selects a basic depression in the basic depression selection step (S320) by the user selecting one basic depression in the basic perpetual keypad displayed in the basic perpetual keypad display step (S310).

If the skip event does not occur in the state where the basic trait is selected, the procedure enters the derivation trajectory input procedure. If a skip event occurs, the derivative trajectory input procedure is skipped to complete a syllable having both the beginning and the neutral trajectory.

If the basic consonant is selected by the basic consonant selection step S320, the character input device displays a derivation consonant keyboard in which phonetic consonants synchronized with the basic consonants selected in the derivation consonant keypad display step S330 are arranged.

The user selects one of the derivations from the derivative consonant keypad displayed in the derivative consonant keypad display step S330, so that the character input device inputs the consonant by selecting the corresponding derivation consonant in the derivation consonant selection step S340 .

An example of inputting the word " six " in the above manner is shown in Fig. First, the basic chief display unit 111 displays basic chiefs ('a', 'b', 'd', 'k', 'g', 'o') on the 3 × 2 basic chord keyboard, o ', the basic chaos selection unit 112 receives' o' and changes to a derivative chaos keyboard interlocked with the basic chaos' o 'by the derivative chaos display unit 113. This derived frontal keyboard is derived from 'o' and 'heh'. If the user selects the 'o' button, the derivation primitive selection unit 114 receives 'o' and completes the initial 'o' input and outputs 'o' to the character input result window.

Next, the basic neutrality display unit 121 displays the basic neutrals ('ㅣ', 'a', 'ㅗ', 'ㅡ', 'ㅓ', 'ㅜ') on the 3 × 2 basic neutron plate, ', The basic neutrality selection unit 122 receives' ㅓ' and changes to a derived neutron plate linked to the basic neutrality 'ㅓ' by the derived neutrality display unit 123. In this derived neutron edition, there are 'ㅖ', 'ㅕ', 'ㅞ', 'ㅔ', 'ㅓ', and 'ㅝ'. If the user selects the 'ㅕ' button, the derivative neutral selection unit 124 receives 'ㅕ', completes the input of 'ㅕ', and outputs 'F' in the character input result window.

Then, the basic longitudinal display unit 131 displays the basic longitudinal key board, and the basic longitudinal selecting unit 132 waits for input. Here, the user generates a skip event to complete the syllable 'F' in order not to input the ending.

In the same way, the remaining two syllables are 'ㅅ', 'ㅅ', 'ㅓ', 'ㅓ', 'ㅅ', 'ㅅ', 'a', 'a', 'a', ' And input a skip event.

Accordingly, since characters can be input using a smaller number of key buttons in a device having a limited size such as a mobile phone, the user convenience can be improved and phonetic completion type characters can be input, The character can be completed, the character input speed can be improved, and the object of the present invention can be achieved.
