Description

[0001] DRAG-BASED HANGLE INPUT DEVICE AND METHOD [0002]

The present invention relates to a drag-based Hangul input device and method, and more particularly, to an apparatus and method for inputting characters in a TV or mobile device environment.

IT service usage environment is gradually changing from PC to TV or mobile device environment.

The PC can receive characters from a user through a QWERTY keyboard having many key buttons, but a TV or a mobile device can receive characters from a user through a QWERTY keyboard of a virtual keyboard due to its structural characteristics.

However, when characters are input through the QWERTY keyboard of the virtual keyboard, the user can not finely control because of the characteristics of the TV interface or the mobile device interface.

Therefore, in recent years, dedicated character plates for TVs and mobile devices have been generated one by one.

In general, a keypad of a portable electronic device such as a mobile phone or a PDA (Personal Digital Assistant) can not have a sufficient number of buttons corresponding to all the characters of the language due to its small size, so that a limited number of buttons are provided It is possible to input all the characters of a specific language.

Therefore, when using the keypad of such a portable electronic device, it is difficult to grasp the position of the corresponding key point to be input by the user because a plurality of keys are arranged on one button at the same time. In addition, There is an inconvenience that you have to press it once.

Especially, in the case of Hangul, according to the Hangul Spelling Uniform, the beginning of Hangul is divided into a, b, c, d, ㅁ,,,,,,, ㅋ, ㅌ, ㅎ, ㄲ, ㄸ, ㅃ, ㅆ, 19, and neutral is a vowel, a, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ,,, ㅠ,,, ㅐ, ㅐ, ㅒ, ㅖ, ㅘ, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ, ㅢ 21, and the seed is a, b, c, d, ㅁ, ㄿ,,,,, ㅋ, ㅌ, ㅎ, ㄲ, ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄿ, ㄾ, ㅀ, ㅄ, and ㅆ.

Therefore, there are 30 kinds of consonants and 21 kinds of vowels in Hangul, and it is very difficult to express all of them using a limited number of buttons.

However, as the mobile communication technology has recently developed, the mobile phone or the PDA uses the mail, the Internet, the chat, the bank, the securities, and the order or payment of various businesses in the business, Trend.

Currently, the most commonly used portable electronic devices have a character input system called a skyrocketing system and an EZ Hangul system. All of the keypads of a portable electronic apparatus adopting such a method are arranged in a form other than 12 rows of 3 rows and 4 rows In recent years, this has been a constraint on the design of mobile phones and other electronic devices that have become increasingly important for aesthetic sense and convenience. In recent years, portable electronic devices have evolved into a level comparable to conventional PCs by adding various functions In order to fully utilize these functions, the input method of the portable electronic device should be able to be effectively input in a narrow space instead of the conventional input method.

In addition, in the conventional character input method using four signals, a character input device capable of inputting a length or a length of a wheel mouse or a track ball is required, and it is difficult to adopt a commonly used keyboard, a mobile phone, Are inputted with four keys, the user's convenience such as constituting a semitone signal by the length of a consonant such as a long consonant and a terminal sound is low, and the input speed is also slowed down.

In addition, in the case of the Hangul input, the state change key for determining the state of the consonant / vowel / pedestal must be separately existed, so that the number of input is increased and the input speed is lowered accordingly.

Accordingly, there is a need for a different-level input method that uses a minimum number of keys and is configured in a manner similar to conventional keyboard and mobile phone input pads, thereby improving the user's convenience and reducing the number of inputs and increasing the input speed.

It is an object of the present invention to provide a drag-based Hangul input device and method which enable a user to input a character relatively easily and easily in a TV or mobile device environment.

In order to achieve the above object, a drag-based Hangul input device according to an aspect of the present invention includes nine consonant buttons having the same size and ten collection buttons divided into three types according to a predetermined frequency of use, A key button unit disposed in the key button unit; A touch screen for outputting data in accordance with a user's touch or drag on an area corresponding to the nine consonant buttons and the arranged ten vowel buttons; And if the consonant button corresponding to the touched consonant button corresponding to the touched consonant button is recognized as a consonant button including a predetermined associated consonant button on the basis of data input from the touch screen, A controller for controlling the key button unit and displaying a consonant corresponding to the associated consonant sound button recognized as being selected by the associated consonant button when dragged from the touched consonant button, The key button part arranges the collection buttons of '-' and 'l' in the largest size according to the frequency of statistical collection use of Korean, and 'ㅗ', 't', 'a' and 'ㅓ' And the vowel buttons of 'ㅛ', '' ',' ㅑ 'and' ㅕ 'are arranged in the smallest size, and the nine consonant buttons' , B, and c in, d, Wh, f, oi, o, ㅈ, the collection frequency of use can set of highest largest size button and wherein the arrangement of the same size.

FIG. 1 is a diagram for explaining a drag-based Hangul input device according to an embodiment of the present invention, and FIGS. 2 to 4 are diagrams for explaining a Hangul input according to an embodiment of the present invention.

1, the drag-based Hangul input device of the present invention includes a key button unit 110, a touch screen 120, a controller 130, and a screen 140.

The key button unit 110 arranges nine consonant buttons having the same size and ten vowel buttons divided in size according to a predetermined frequency of use in the screen 140.

For example, as shown in FIG. 2, the key button unit 110 includes nine consonant buttons having the same size, i.e., a, b, c, d, k, Buttons arranged in three sizes according to the order of frequency are arranged on the screen 140. The buttons 140,

The key button unit 110 arranges the 'l, l' button among the three types of collection buttons in the largest size according to the predetermined frequency of use order and arranges it on the screen 140, Buttons are arranged on the screen 140 and the buttons are arranged in a third larger size on the screen 140 and nine consonants Buttons are formed in the same size as the largest-sized vowel buttons, and are arranged on the screen 140.

Here, the frequency of use is preset based on the statistical data.

For example, consonants 'ㅇ, ㄱ, ㄱ,,, ㅅ' and vowel,,,, ㅓ, ㅡ, ㅗ are statistically most commonly used, accounting for approximately 74.9% Based on the frequency of use, the size of the collection button is divided into three categories.

The touch screen 120 outputs data according to the operation of the user corresponding to the nine consonant buttons and the ten vowel buttons, i.e., touch or drag.

For example, when the 'A' button is touched, the touch screen 120 outputs the data of the touched 'A' button area to the controller 130, and when the 'A' button is touched by the user's finger or pen And outputs the data of the dragged area to the control unit 130 when the button is dragged.

When the controller 130 recognizes that the touched consonant button is related to the touched consonant button based on the data input from the touch screen 120 and is recognized as a consonant button including a predetermined associated consonant button, (110) is controlled to be placed on the associated consonant sound button (140), and when dragged from the consonant button touched by the user's finger or pen to the associated consonant sound button, the associated consonant sound button So that the corresponding associated consonant is displayed on the screen 140.

The predetermined consonant consonant corresponding to 'a' is 'ㅋ, ㄲ', 'c', '' ',' , The predetermined consonant corresponding to the consonant is' ㅌ ', the predetermined consonant corresponding to' ㅂ 'is' ψ, ㅃ' and the predetermined consonant corresponding to 'g' is' , And the predetermined associated consonant corresponding to 'o' is 'h'.

3, when the control unit 130 receives the data of the 'A' button region from the touch screen 120, the control unit 130 determines whether the 'A' button is touched based on the input 'A' And controls the key button unit 110 so that the associated consonant sound buttons corresponding to the 'A' button, that is, the 'ㅋ, ㄲ' button are disposed on the left and right sides with respect to the 'A' button, Or dragged from the 'A' button to the 'ㄲ' button while being touched by the pen, and then the touch is released or is dragged from the 'A' button to the 'ㄲ' button while being touched, Button is selected, the consonant corresponding to the selected 'ㄲ' button is displayed on the screen 140. In this case,

Further, the control unit 130 recognizes that the dragged and the vowel buttons are selected from the selected associated consonant buttons to the vowel buttons, constitutes a vowel composed of consonants corresponding to the selected associated consonant buttons and vowels corresponding to the selected vowel buttons, On the screen (140).

For example, the control unit 130 recognizes that the 'a' button has been selected when the user touches the 'ㄲ' button with the 'a' button while being touched by the user's finger or pen, And a syllable 'C' consisting of a vowel 'a' corresponding to the selected 'a' button and a syllable 'C' composed of a consonant corresponding to the selected 'A' button are displayed on the screen 140.

When the 'A' button is touched by the finger or pen of the user, the controller 130 controls the 'K' button to be located on the left and right sides of the 'A' button, Button is dragged from the 'A' button to the 'ㄲ' button in the touched state and then is touched or dragged from the 'A' button to the 'ㄲ' button in the touched state, The user recognizes that the 'ㄲ' button is selected and displays 'ㄲ' on the screen 140. When the user's finger or pen is touched and dragged from the 'ㄲ' button to the 'a' button, And a syllable consisting of a vowel 'a' corresponding to the selected 'a' button and a consonant corresponding to the selected 'ㄲ' button, Is displayed on the screen 140, and the associated consonant sound button Button is not displayed on the screen 140.

If it is recognized that the touched consonant button is a consonant button that does not include the associated consonant button, the control unit 130 causes the consonant corresponding to the consonant button that does not include the associated consonant button to be displayed on the screen, When a vowel button is dragged from a consonant button that does not include a consonant button, the vowel button is recognized as being selected, and a consonant corresponding to a consonant button that does not include the associated consonant button and a vowel corresponding to the selected vowel button are constituted. To be displayed on the screen.

For example, the controller 130 recognizes that the 'ㅁ' button is selected when the 'ㅁ' button is touched or touched by the user's finger or pen, or the ㅁ button is touched while being dragged downward When the user presses the 'ㅁ' button from the 'ㅁ' button in a touched state so that 'ㅁ' is displayed on the screen 140, it is recognized that the 'a' button is selected and 'a' is displayed on the screen 140 When the touch is released from the 'a' button to the 'ㅣ' button and the touch is released, it is recognized that the 'l' button is selected and the consonants 'ㅁ' and 'a' And a syllable 'Ma' consisting of vowel 'l' corresponding to the corresponding vowel 'a' and 'l' buttons, and to display the composed syllable 'Ma' on the screen 140.

On the other hand, if the controller 130 recognizes that one of the six consonant buttons including the associated consonant button is touched, the control unit 130 displays a cancel button for canceling consonant input canceling to stop the display of the associated consonant button And controls the key button unit 110 to be disposed.

For example, as shown in FIG. 4, when the control unit 130 receives the data of the 'A' button area from the touch screen 120, the 'data' button is touched based on the data of the 'A' , And a predetermined related consonant sound button corresponding to the 'A' button is arranged on the left and right sides with respect to the 'A' button, and a state of being touched by the user's finger or pen Button is dragged from the 'a' button to the 'ㄲ' button arranged, and when dragging from the 'ㄲ' button to the cancel button while being touched, the 'ㅋ, ㄲ' button arranged to recognize that the consonant input is canceled is displayed on the screen 140 ).

As described above, according to the present invention, when the 'a' button is touched by the user's finger or pen, the 'a' button is dragged from the touched 'a' button to the 'a' Quot; is displayed on the screen. That is, a syllable consisting of a consonant and a vowel is input and displayed on the screen according to a user's action of touch (select) -> drag -> (touch) release.

As described above, according to the present invention, there is an effect that user's convenience of inputting characters can be improved and fatigue of a user can be lowered. In particular, since a relatively small number of gestures are required for button selection and relatively few character buttons are used, There is an advantage that it is possible to reduce the fatigue of the selection operation and at the same time to achieve clear button input.

The drag-based Hangul input device according to an embodiment of the present invention has been described with reference to FIGS. 1 to 4, and a drag-based Hangul input method according to an embodiment of the present invention will be described with reference to FIG. 5 . 5 is a flowchart illustrating a drag-based Hangul input method according to an embodiment of the present invention.

As shown in FIG. 5, nine consonant buttons having the same size and ten vowel buttons divided in size according to the preset frequency of use are displayed on the screen (S500).

For example, nine consonant buttons having the same size, i.e., a collection button divided into three sizes according to the order of 'a, b, c, d, k, g, Button 140 is displayed on the screen 140, and among the collection buttons divided into three sizes according to the preset frequency of use, '-, -, -, -, -, -, -, , and l 'buttons are formed in the largest size on the screen 140, and the' ㅗ, ㅜ, a, ㅓ 'buttons are formed in the second largest size on the screen 140, Button on the screen 140 and displays nine consonant buttons on the screen 140 in the same size as the largest-sized vowel buttons.

In operation S501, it is determined whether or not the touched consonant button corresponding to the touched consonant button based on the data input through the touch screen 120 is a consonant button including a predetermined associated consonant button.

As a result of the determination, if it is determined that the touched consonant button corresponds to the touched consonant button and is a consonant button including a predetermined associated consonant button, the predetermined consonant tones button and the cancel button are arranged on the screen 140 (S502).

For example, when the data of the 'A' button area is input from the touch screen 120, the 'A' button is recognized as being touched based on the data of the 'A' button area, Place the consonant buttons, ie, 'ㅋ, ㄲ', on the left and right sides of the 'A' button, and place the cancel button.

It is determined whether or not the user has been dragged from the consonant button touched by the user's finger or pen to the cancel button (S503).

As a result of the determination, if it is dragged from the touched consonant button to the cancel button, the associated associated consonant tones button and the cancel button are not displayed on the screen 140 (S504).

However, if it is determined that the button is not dragged from the touched consonant button to the cancel button, it is determined whether the button is dragged to another button except for the cancel button (S505).

As a result of the determination, if it is not dragged with another button, it is determined whether or not the user's finger or pen has released the touch (S506).

As a result of the determination, if the touch is released, the consonant or vowel corresponding to the touched button is displayed on the screen 140 (S507).

For example, when the user touches the user from the 'A' button to the 'ㄲ' button while being touched by the user's finger or pen and then is touched off or is dragged downward from the ㄲ button in the touched state, And displays the consonant 'ㄲ' corresponding to the selected 'ㄲ' button on the screen 140.

In addition, when the user touches the finger or the pen and then the finger is dragged from the 'ㄲ' button to the 'a' button and is touched, the 'a' button is recognized as selected and the consonant ' A syllable consisting of a vowel 'a' corresponding to the selected 'a' button and a syllable 'ca' composed of a vowel 'a' corresponding to the selected 'a' button.
