Description

How to delete Hangul in Korean input device of Cheonjiin method {METHOD FOR DELETING KOREAN IN KOREAN INPUT DEVICE OF CHEON ・ JI ・ IN TYPE}

The present invention relates to a Hangul input device, and more particularly to a method for deleting a Hangul input to the Hangul input device of the Cheonjiin method.

The Cheonjiin type Hangul input device refers to a Hangul input device that generates vowels or neutrals by combining Cheon (·), Ji (ㅡ), and phosphorus (ㅣ) Samjae, which are the basic principles of Hangul creation. The Korean input device of the Cheonjiin method is used in various devices such as a mobile phone and a key phone.

Examples previously applied for the Korean input device of Cheonjiin method include a Korean patent publication number "2000-0042231" (Korean input device) published on July 15, 2000, and a Korean patent published on March 7, 2002. Publication number "2002-0017384" (Korean input method in a mobile phone), domestic patent publication number "2002-0019720" (character input method of a wireless terminal) published on March 13, 2002 and the like.

The Hangul input device of the Cheonjiin method as described above will be described with reference to FIG. 1 as follows. 1 is a block diagram of a keypad of a conventional mobile communication terminal. As shown in FIG. 1, the keypad of the mobile communication terminal includes the cloth (·), ji (ㅡ), phosphorus (ㅣ) samjae key, (ㄱㅋ), (ㄱㄹ), (ㄷㅌ), (ㅂㅅ), (ㅅㅎ). It consists of the consonant keys of,, () and (). When inputting Hangul using the keypad of the mobile communication terminal configured as described above, a combination of the Samjae key and the consonant key is input. For example, the word "Korean" is (ㅇ) → (ㅡ) → (·) → (ㄹ) [(ㄴㄹ) key pressed twice] → (ㅣ) → (ㅁ) [(ㅇㅁ) key pressed twice] Enter the key in the order → (ㅣ) → (·) → (ㄹ) [press the (b) key twice].

Users of the Korean input device of Cheonjiin type are inputting Hangul in the same manner as described above.

However, the currently used Hangul input device of Cheonjiin deletes the input Hangul by one letter, that is, syllable units. For example, when a user incorrectly inputs "our" when he / she wants to input "Korean", when the delete key, that is, the (cancel) key of FIG. 1 is inputted, the last (water) input is deleted. Therefore, the user is inconvenient to re-enter (word) from the beginning. If you delete the phoneme by phoneme or vowel unit, that is, when you press the (Cancel) key, (Water) (d) is deleted, and when you press the (Cancel) key again, If deleted, the above inconvenience will be eliminated.

Accordingly, an object of the present invention is to provide a method of deleting Hangul input by phoneme by the Korean input device of Cheonjiin.

Another object of the present invention is to provide a method of deleting Hangul input by vowel units in a Hangul input device of Cheonjiin.

The present invention for achieving the above object is provided with a key assigned to each of the cloth (·), JI (-), phosphorus (ㅣ) samjae and at least one consonant is assigned to one key and according to the number of key presses In the method of deleting the input Hangul input by the Hangul input device any one of the consonants assigned to the key is input, to create a vowel by combining the cheon (·), ji (ㅡ), jae (jae) samjae, When the delete key of the Hangul input device is input, checking a final phoneme of a last input syllable; deleting the consonant when the last phoneme is a consonant; and when the last phoneme is a vowel, the last input of Samjae It characterized in that it comprises a process of deleting one.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that in the following description, only parts necessary for understanding the operation according to the present invention will be described, and descriptions of other parts will be omitted so as not to distract from the gist of the present invention.

First, the Hangul input device of the Cheonjiin method refers to an input device that generates vowels or neutrals by combining Cheon (ㆍ), Ji (ㅡ), and phosphorus (재) materials as described above. The Hangul input device may be a variety of input devices such as a mobile communication terminal and a key phone. In the present invention, a mobile communication terminal which is most commonly used as a Korean input device of Cheonjiin will be described as an embodiment.

2 is a block diagram of a mobile communication terminal. Referring to FIG. 2, the mobile communication terminal includes a display unit 2, a key input unit 4, a memory unit 6, a controller 8, a receiver 10, a frequency synthesizer 12, a transmitter 14, and a voice processor. (16), a duplexer (18).

The duplexer 18 extracts only a predetermined band signal among the signals received from the antenna ANT and outputs the signal to the receiver 10, and outputs the signal received from the transmitter 14 to the antenna ANT.

The transmitter 14 converts the signal from the voice processor 18 and the signal received from the frequency synthesizer 12 into a signal of the transmission band and outputs the signal to the duplexer 18.

The receiver 10 outputs a portion corresponding to the voice signal among the signals received by the control of the controller 8 to the voice processor 18, and outputs a signal that is not a voice signal to the controller 8. The frequency synthesizer 12 generates and outputs frequencies to be output to the transmitter 14 and the receiver 10 under the control of the controller 8.

The voice processor 18 decodes the signal received from the receiver 10, converts the signal into an electrical voice signal, and outputs the signal to the speaker SPK. Then, the speaker SPK receives the electric voice signal, converts it into an audible sound, and outputs the audible sound. In addition, the microphone MIC converts a signal of an audible frequency into an electrical signal and outputs it to the voice processor 18. The voice processor 18 then codes the received electrical voice signal and outputs it to the transmitter 14.

The display unit 2 displays the state and operation process of the mobile communication terminal, and displays the input Hangul according to an embodiment of the present invention.

The key input unit 4 includes a plurality of keys used in a mobile communication terminal, and according to an embodiment of the present invention, as shown in FIG. 1, the cloth (·), the paper (ㅡ), the phosphorus (jae) samjae key. And a plurality of consonant keys.

The memory 6 temporarily stores driving programs necessary for the control of the controller 8 and data generated during the control operation. Then, the Hangul inputted according to the embodiment of the present invention is stored, and the Hangul inputted with the memory map (Table) shown in Table 1 below is stored.

In the memory map of Table 1, vocal voices are voices representing primary, neutral, and final. As shown in the memory map of Table 1, two bytes each of the consonant and the final consonant are allocated because the consonant of the consonant of the letter and the consonant of the consonant of the letter consist of two terminal sounds. The allocation of 5 bytes of neutral, which is a vowel, means that the vowel (지), ㅒ, ㅔ, ㅖ, ㅘ, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ, ㅢ) This is because Samjae needs up to five.

In addition, the controller 8 controls the overall operation of the mobile communication terminal. In particular, according to the present invention, when the delete key is input when the Hangul is input, the controller 8 checks the last phoneme of the last syllable and deletes the consonant when the last phoneme is a consonant. If the last phoneme is a vowel, it deletes the last input one of Cheon (·), 지 (ㅡ), and phosphorus (ㅣ) Samjae. At this time, the phoneme refers to the minimum unit of the phoneme, and one or more of these phonemes form a syllable.

In addition, when the delete key is input when the Hangul is input, the controller 8 checks the vowels of the last input syllables, and deletes the initial and neutral voices when the voices are initial and final voices. In case of neutral, the last input one of cloth (·), ji (ㅡ), phosphorus (ㅣ) samjae is deleted.

The operation of the controller of the mobile communication terminal having the above configuration will be described in more detail with reference to FIGS. 3 and 4 as follows.

The embodiments of the present invention are largely divided into two types. As described above, one checks whether the last phoneme of the last syllable of the input Hangul is a vowel / vowel or not. Deletion of one of the phosphorus (ㅣ) samjae. The other method is to delete one of cheon (·), ji (ㅡ), phosphorus (jae) samjae, jong or jong by checking the last vowel of the last syllable of the last syllable of Hangul. to be.

First, the process of deleting the consonants or vowels by checking whether the last phoneme of the last syllable of the Hangul is input is described in detail with reference to FIG. 3. If the key is input, the controller 8 checks the last phoneme of the last syllable of the Hangul inputted in step 104. If the last phoneme is a consonant in step 106, the controller 8 deletes the consonant in step 108. For example, after inputting "Korean", the delete key is input, and the control section 8 deletes (d) of (word) and displays "urima" on the display unit. If the last phoneme is a vowel in step 110, the controller 8 deletes the last input one of the cloth (·), the paper (−), and the material (ㅣ) samjae in step 112. For example, after inputting "urima", the delete key is input, and the control unit 8 deletes the cloth of (e), and displays "urimi" on the display unit. Thereafter, when the delete key is input again in step 114, the controller 8 repeats the above process. That is, when the delete key is re-entered in the "Uri" state, the controller 8 deletes the phosphorus of (U) and displays "Uri".

On the other hand, when the consonant is a double consonant or a consonant consonant, the controller 8 deletes the double consonant or the consonant in units of terminal sounds. For example, after inputting "communication" and inputting a delete key, the control unit 8 deletes (a) of (i) and displays "communication a" on the display unit.

By checking whether the phoneme / vowel is the last phoneme of the last syllable input as described above and deleting the consonants and vowels, the user can delete the Hangul input by phoneme units rather than syllable units.

Meanwhile, referring to FIG. 4, a method of checking whether the last consonant of the last syllable of the input Hangul is the initial / neutral / final is described with reference to FIG. 4. If the (Cancel) key is input, the controller 8 checks the last voice of the last syllable of the Hangul input in step 204. If the last voice is final in step 206, the controller 8 deletes the final voice in step 208. If the last voice is neutral in step 210, the controller 8 deletes the last input one of the samjaes in step 212. If the last voice in the first consonant, the controller 8 deletes the first consonant. Thereafter, when the delete key is input again in step 218, the controller 8 repeats the above process. When the above process is described using "fighting chicken" as an example, after inputting "fighting chicken" and then entering a delete key, the controller 8 deletes (a) of (fowl) and displays "fighting moon" on the display unit. Upon re-entering the delete key, the controller 8 deletes (d) of (month) and displays "fight" on the display. After that, when the delete key is input again, the control unit 8 deletes the cloth of (c) and displays "fighting" on the display unit. When the delete key is input again, the control unit 8 displays the (D) key. After deleting the phosphorus and displaying "fighting" on the display unit, when the delete key is input again, the controller 8 deletes (c) of "fighting" and displays "fighting" on the display.

By checking whether the last vowel of the last syllable of the Hangul inputted as above is the initial / neutral / finality and deleting the initial or neutral or the finality, the user can delete the Hangul inputted by the vowel unit instead of the syllable unit.

In the above-described present invention, a specific embodiment of the mobile communication terminal has been described. However, the present invention can be implemented without departing from the scope of the present invention in a Korean input device having a natural environment such as a key phone. Therefore, the scope of the invention should not be defined by the described embodiments, but by the equivalents of the claims and the claims.

As described above, by deleting the input Hangul by the phoneme or vowel unit in the Hangul input device of Cheonjiin method, the user can edit the Hangul more conveniently.
