The present invention relates to a text input method and an electronic device using the same, and more particularly, to a text input method for inputting a text using a joystick and an electronic device using the same.

Recently, with the development of the electronics industry, the supply of various small portable terminals has been increasing. Representative examples thereof include mobile communication terminals, PDAs, MP3s, PMPs, and digital cameras. Such a terminal has a character input function applied thereto, and generally, a character input function for inputting a character using a key designated with a specific letter or number is applied.

However, there is a demand for a method of reducing the number of keys while minimizing the size of the terminal and inputting characters even in a small operation space. 1 is a view schematically showing a conventional character input apparatus.

Referring to FIG. 1, a character input device of a conventional terminal has a joystick 10. The joystick can move in eight directions (A, B, C, D, E, F, G, H), and outputs joystick direction data corresponding to the movement direction.

The character input apparatus detected the direction data of the joystick 10 and displayed the character data generated based on the detected direction data set on the screen.

2 is a diagram illustrating a character input method of a conventional character input apparatus. Referring to FIG. 2, a key manipulation combination of the joystick 10 corresponding to each consonant and a vowel when the consonant and the vowel are input by the character input method of the conventional character input apparatus is shown.

Specifically, when the consonant is input, 'a' is inputted by manipulating the joystick 10 in the direction of ABCEH, 'b' is ADFGH, and 'ㅁ' is ABCEHGFD or ADFGHECB. And, when inputting the vowel, 'ㅏ' is the BGE, 'ㅑ' is input by operating the joystick 10 in the BGEE direction. Alternatively, when inputting a double consonant, repeated input, for example, 'ㄲ' was input by operating the joystick 10 in the ABCEHABCEH direction.

Therefore, the key operation when entering 'ㄹ', 'ㅈ', or 'ㅎ' has a lot of differences from when writing consonants, which not only decreases intuition, but also allows the user to set the key operation sequence through a separate learning process. I had to remember. In addition, the number of key manipulations is too large, causing a problem that the user feels uncomfortable.

Accordingly, an object of the present invention is to provide a character input method capable of easily inputting characters with little key manipulation using a four-way joystick, and an electronic device using the same.

Another object of the present invention is to provide a character input method capable of inputting a character according to actual handwriting stroke order and an electronic device using the same without a separate learning process for inputting a character.

Character input method according to the present invention for achieving the above object is a step of receiving direction data sequentially output from the joystick operated in accordance with the actual writing stroke order, if it is determined that the input of the direction data is completed, the input direction data Storing the data sequentially, and generating a character by combining the stored direction data.

Specifically, the step of receiving the direction data, the consonant is input by the direction data according to the movement of the joystick in the direction "→", "↓" and "o" data by pressing the joystick, the joystick It is preferable to receive the vowel by the direction data according to the movement in the direction of "→ " and " ↓ " and ". &Quot; data by pressing the joystick.

In the storing step, when the confirmation signal is input from the confirmation key, it is determined that the input of the direction data is completed.

Meanwhile, the electronic device of the present invention includes a key input unit including a joystick and a confirmation key, and sequentially inputting direction data corresponding to movement of the joystick operated according to the actual writing stroke order, and storing the sequentially input direction data. When the confirmation signal is input from the storage unit and the confirmation key, it is determined that the input of the direction data is completed, and the input direction data is sequentially stored in the storage unit, and the characters are generated by combining the stored direction data. It includes a control unit.

Preferably, the key input unit inputs consonants based on direction data according to the movement of the joystick in the direction of " → "and " ↓ " and " o " data by pressing the joystick. , The vowel is input by the direction data according to the movement in the "↓" direction and the "." Data by pressing the joystick.

Hereinafter, with reference to the drawings will be described in detail the present invention.

3 is a block diagram of an electronic device according to an embodiment of the present invention.

This electronic device is a terminal that provides a character input method that can input characters according to the actual handwriting stroke similar to the actual handwriting method using a four-way joystick. For example, a mobile communication terminal, a PDA, an MP3, and a PMP. , Digital camera, and camcorder

Referring to FIG. 3, the electronic device includes a key input unit 310, a control unit 320, a buffer 330, a storage unit 340, a GUI unit 350, and a display unit 360.

The key input unit 310 is provided with a joystick and a confirmation key for character input. The key input unit 310 transmits the direction signal input through the joystick and the confirmation signal input through the confirmation key to the controller 320.

The controller 320 temporarily stores the direction data extracted from the direction signal received from the key input unit 310 in the buffer 330 sequentially. When the confirmation signal is input from the key input unit 310, the controller 320 determines that one of one consonant, a vowel, and a number is input, and sequentially stores the direction data temporarily stored in the buffer 330. The direction data stored in the 340 and the buffer 330 are deleted.

The controller 320 generates a character by combining the direction data stored in the storage 340, and controls the GUI unit 350 to display the generated character on the display 360. The GUI unit 350 displays the text generated by the controller 320 on the display 360 as a graphic.

4 is a diagram illustrating a key input unit according to an embodiment of the present invention.

Referring to FIG. 4, the key input unit 310 includes a four-way joystick 312 and a confirmation key 314. At this time, the joystick 312 is operable in four directions of "←" (1), "↑" (2), "→" (3), and "↓" (4), and can be pressed without direction.

Specifically, when the joystick 312 is pressed without direction, "o" is input for consonant and numeric input, and "." Is input for vowel input. Then, a letter, that is, a Korean character and a number, is input using the " ↓ " (4) direction, " " (3) direction, " o " or " Upon entering a character, when one of the consonants, vowels, and numbers is completed and the confirmation key 314 is pressed, any one of the entered consonants, vowels, and numbers is displayed.

At this time, moving the joystick 312 in the direction "↑" (2) can change the character input mode. Types of character input modes include Korean, numbers, English, and special characters. In detail, the initial character input mode is a Korean input mode. When the joystick 312 is moved once in the direction of "↑" (2), the initial character input mode is changed to the numeric input mode. The order of the input modes is not fixed, and may be changed by frequency of use or convenience for use.

And, in the character input, the direction of " ← " (1) of the joystick 312 is not used. When the character is input, when the joystick 312 is moved in the direction of "←" (1), the controller 320 does not perform any operation or outputs a warning sound or a message informing of an input error.

5 is a diagram illustrating a character input method of an electronic device according to an embodiment of the present invention.

Referring to FIG. 5, when a consonant, a vowel, and a number are input using the joystick 312, a key manipulation combination of the joystick 312 corresponding to each consonant, the vowel, and the number is shown.

Specifically, when the consonant "a" is input, the joystick 312 is moved in the direction of "→" (3) and "↓" (4) according to the actual writing stroke order. Then, when the confirmation key 314 is pressed, "a" is displayed. In the case of inputting "ㄹ", the joystick 312 is moved to "→" (3), "↓" (4), "→" (3), "↓" (4), and "→" according to the actual writing order. Move in the (3) direction. Alternatively, since the number of key manipulations increases according to the actual writing stroke order, it can be recognized even when inputting in the directions " → " (3) and " "

In the case of inputting "s", the joystick 312 is moved in directions "↓" (4) and "↓" (4). When entering "o", the joystick 312 is pushed without direction. In the case of inputting "vo", the joystick 312 is input in directions "↓" (4), "→" (3), "↓" (4) and "↓" (4).

At this time, in the case of inputting consonants, the consonants are input by pressing the confirmation key 314 twice after inputting the consonants. For example, in the case of inputting “ㄲ”, the joystick 312 is moved in the direction of “→” (3) and “↓” (4), and when the confirmation key 314 is pressed twice, “ㄲ” is displayed. do.

In the case of inputting a consonant sound using two consonants as a support, after inputting two consonants, the confirmation key 314 is pressed to input a consonant sound. For example, when inputting "ㄹㄱ", the joystick 314 is moved in the direction of "→" (3), "→" (3), "→" (3), and "↓" (4). When the confirmation key 314 is pressed, "ㄹ" is displayed.

In the case of inputting the vowel “ㅏ”, the joystick 312 is moved in the direction of “↓” (4) in accordance with the actual writing stroke order, and is pressed without direction to input “·”. In the case of inputting "ㅞ", move the joystick 312 in the direction of "→" (3), press twice to input "·", "·", and then enter "↓" (4) and "↓". Move in the (4) direction.

And, if you want to enter a number, move the joystick 312 in the direction "↑" (2) to change the character input mode to the number input mode. In the case of inputting "2", the joystick 312 is pressed to input "o" and moves in the direction of "→" (3). When inputting "8", the joystick 312 is pressed twice to input "o" and "o".

That is, characters can be input by moving and pressing the joystick 312 in the direction of " → " (3) and in the direction of " ↓ " (4), thereby reducing the number of key manipulations.

6 is a flowchart provided to explain a character input method of an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 6, in the text input mode, the controller 320 determines whether a key is input (S610). Specifically, when the key signals corresponding to the joystick 312 and the confirmation key 314 included in the key input unit 310 are input, the controller 320 determines that there is a key input.

If it is determined that there is a key input, the controller 320 temporarily stores the direction data extracted from the direction signal corresponding to the input key in the buffer 330 (S620).

The controller 320 determines whether the confirmation key 314 is input (S630). If it is determined that there is no input of the confirmation key 314, the controller 320 determines that the character input is not completed. The controller 320 continuously determines whether there is a key input, and temporarily stores the direction data extracted from the input direction signal in the buffer 330 sequentially.

On the other hand, if it is determined that the confirmation key 314 is input, the control unit 320 determines that the character input is completed. When it is determined that there is an input of the confirmation key 314, the controller 320 stores the direction data stored in the buffer 330 in the storage unit 340 and deletes the direction data stored in the buffer 330 (S640).

The controller 320 generates a character by combining the direction data stored in the storage unit 340 and controls the GUI unit 350 to display the generated character (S650).

As an example, assume that "Kana" is entered. Types of Hangul input modes include consonant mode, vowel mode, and consonant support mode. The initial Hangul input mode is the consonant mode. In the initial consonant mode, when the user moves the joystick 312 in the direction of " → " (3) and " ↓ " (4), the controller 320 moves in the directions of " → " Corresponding direction data is sequentially stored in the buffer 330. When the user presses the confirmation key 314, the controller 320 determines the type of the Hangul input mode.

If the Hangul input mode is the consonant mode, the controller 320 determines whether the direction data stored in the buffer 330 is a vowel element. If it is determined that the element is not a vowel element, that is, the consonant element, the controller 320 switches the Hangul input mode to the vowel mode and stores the direction data stored in the buffer 330 in the storage unit 340. This is because the vowel comes after the consonants due to the characteristics of Hangeul. The controller 320 controls the GUI unit 350 to delete the direction data stored in the buffer 330 and to display "a" generated by combining the direction data stored in the storage 340.

In the vowel mode, when the user moves the joystick 312 in the direction of "↓" (4) and presses once to input "·", the control unit 320 corresponds to the direction of "→" (3) and "." Direction data is sequentially stored in the buffer 330. When the user presses the confirmation key 314, the controller 320 determines the type of the Hangul input mode.

Since the Hangul input mode is the vowel mode, the control unit 320 switches the vowel mode to the consonant receiving mode and stores the direction data stored in the buffer 330 in the storage unit 340. This is because consonants may come after vowels due to Korean characteristics. In addition, the controller 320 controls the GUI unit 350 to delete the direction data stored in the buffer 330 and to display "ㅏ" generated by combining the direction data stored in the storage unit 340. As a result, “a” is displayed on the display unit 360.

In the consonant support mode, when the user moves the joystick 312 in the directions "↓" (4) and "→" (3), the control unit 320 moves in the directions of "↓" (4) and "→" (3). Corresponding direction data is sequentially stored in the buffer 330. When the user presses the confirmation key 314, the controller 320 determines the type of the Hangul input mode.

Since the Hangul input mode is the consonant support mode, the controller 320 switches the consonant support mode to the consonant mode and stores the direction data stored in the buffer 330 in the storage unit 340. This is because, after the consonants, the letters start with the consonants again. Then, the controller 320 controls the GUI unit 350 to delete the direction data stored in the buffer 330 and display "b" generated by combining the direction data stored in the storage unit 340. As a result, “liver” is displayed on the display 360.

In the consonant mode, when the user moves the joystick 312 in the direction of "↓" (4) and presses once to input "·", the control unit 320 corresponds to the direction of "→" (3) and "." Direction data is sequentially stored in the buffer 330. When the user presses the confirmation key 314, the controller 320 determines the type of the Hangul input mode.

Since the Hangul input mode is the consonant mode, the controller 320 determines whether the direction data stored in the buffer 330 is a vowel element. Since "·" is a vowel element, the control unit 320 determines whether a previous consonant receiver exists.

Since the previous consonant bearing "b" exists, the control unit 320 determines the beginning consonant of a new letter without using the previous consonant bearing as a support. In other words, it is not "liver" but "ghana". Accordingly, the control unit 320 switches the Hangul input mode to the consonant receiving mode and stores the direction data stored in the buffer 330 in the storage unit 340. In addition, the controller 320 controls the GUI unit 350 to delete the direction data stored in the buffer 330 and to display "ㅏ" generated by combining the direction data stored in the storage unit 340. As a result, “Kana” is displayed on the display 360.

As described above, according to the present invention, it is possible to easily input a character with a small number of key operations according to the actual writing stroke order using the four-way joystick, thereby increasing user convenience.

In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the specific embodiments described above, but the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be understood from the technical spirit or the prospect of the present invention.
