Description

Method and System for Inputting the Korean Alphabet}

The present invention relates to a character input method, and more particularly to a Hangul input method and system.

Hangul is different from English, French, German, and Hanja where each phoneme is listed one-dimensionally. It has a writing system that is arranged in one syllable.

In the method of inputting characters, a one-dimensional character has a relatively simple character input system because a word is completed by simply phoneme order and space, while Hangul is not only two-dimensionally arranged, but also When two or more consonants, except barbarian, are repeated, such as weights and strokes, it is necessary to decide how to arrange these consonants, and since more than 14 consonants and theoretically infinite vowels can exist, more complex characters can be entered. A system is required.

Recently, with the rapid development of electric and electronic technology, various electronic devices such as mobile phones, PDAs, pagers, small game machines, remote controllers, cameras, etc., such as CDMA, TDMA, GSM, IMT-2000, WCDMA, etc., have been miniaturized and advanced. It is becoming. However, with such miniaturization, as the functions have been improved, the desire to express characters on electronic devices has increased, and the necessity of inputting characters has been increasing. In particular, various methods and devices for inputting Hangul have been developed in mobile phones with limited input keys.

Meanwhile, in the existing mobile phones, Korean characters were inputted by a combination of a total of 12 buttons consisting of numeric keys (1-9) and special keys (*, #) as Korean input methods. It was a method of inputting a button, but the touch screen requires input of a button made in software, which causes a problem in that the input speed decreases. In addition, there is a problem in that key input becomes difficult when the button area is narrowed when individual key arrangements are made, rather than button combinations, due to a decrease in input speed.

The present invention is to solve the above-described problems, to provide a Hangul input method and system that can easily input Hangul as a technical problem.

According to an aspect of the present invention, there is provided a Hangul input method comprising: displaying a Hangul input window including a consonant button, a vowel button, and a conversion button for the consonant or a vowel; Determining whether a second button is touched by dragging the first button among the buttons included in the displayed Hangul input window; And when it is determined that the second button is touched by dragging, combining a character corresponding to the first button and a character corresponding to the second button.

In one embodiment, in the combining step, determining whether the second button is the conversion button; And when it is determined that the second button is the conversion button, converting a character corresponding to the first button according to a function of the preset conversion button.

In this case, when it is determined that the second button is not the conversion button, the character corresponding to the first button and the character corresponding to the second button are combined.

On the other hand, if it is determined that the second button is dragged and not touched, the method may further include completing a character combination up to a character corresponding to the first button.

In one embodiment, the consonant button includes a button corresponding to the 'b', 'b', 'c', 'ㅂ', 'ㅅ', 'ㅇ', 'ㅈ', the collection button ' It is characterized in that it comprises a button corresponding to |, '-'.

In one embodiment, when the first button is a button corresponding to 'b', and the second button is a button corresponding to 'c' or 'b', the letter corresponding to the first button and the first button Characters corresponding to the two buttons is characterized by combining the letters corresponding to 'ㄹ' or 'ㅁ'.

In one embodiment, when the first button is a button corresponding to the 'b', 'c', 'ㅂ', 'ㅅ', 'ㅈ', the second button is the same as the first button, Characters corresponding to the first button and the character corresponding to the second button is characterized by combining the letters corresponding to 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ'.

In one embodiment, when the first button is any one of the buttons corresponding to 'ㄱ', 'ㄷ', 'ㅂ', 'ㅈ', 'ㅇ', and the second button is the conversion button, Characters corresponding to the first button is characterized by converting the characters corresponding to 'ㅋ', 'ㅌ', 'ㄷ', 'ㅊ', 'ㅎ'.

In one embodiment, when the first button is a button corresponding to 'ㅡ', and the second button is the conversion button, when the conversion button is touched in a downward direction, the letter corresponding to 'ㅡ' is' And converts the character corresponding to '' into a character corresponding to 'TT' when the conversion button is touched in the upward direction.

In one embodiment, when the first button is a button corresponding to 'ㅣ', and the second button is the conversion button, when the conversion button is touched and dragged leftward, the corresponding button corresponds to 'ㅣ'. Converts a character into a character corresponding to 'ㅓ', and converts the character corresponding to 'ㅣ' into a character corresponding to 'ㅏ' when the conversion button is touched and dragged in the right direction. .

The size of the second button that can be combined with the first button and the size of the second button that cannot be combined with the first button among the buttons included in the displayed Korean input window may be differently displayed.

In addition, the Hangul input window may be displayed by a touch screen or a g-speak method, and the user may arrange an arrangement of a consonant button, a vowel button, and a conversion button for the consonant or vowel included in the Hangul input window. It can be displayed differently according to the setting of.

According to another aspect of the present invention, a Hangul input system includes: a display unit configured to display a Hangul input window including a consonant button, a vowel button, and a conversion button for the consonant or a vowel; A drag determination unit that determines whether a second button is touched by dragging the first button among the buttons included in the displayed Hangul input window; A conversion button determination unit determining whether the second button is the conversion button when it is determined that the second button is dragged and touched; And a character conversion unit converting a character corresponding to the first button according to a function of the preset conversion button when it is determined that the second button is the conversion button.

According to the present invention, there is an effect that the character input can be simplified by inputting at least one that has been input at least twice.

In addition, the present invention is not limited to the arrangement of the button has the effect that the user can place the Hangul input button as desired.

In addition, the present invention has an effect that a wider button area can be used by deactivating or displaying a button that is not combined.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a Hangul input system according to an embodiment of the present invention. As shown, the Hangul input system 100 includes a display 110 and a controller 120.

The display 110 displays a Korean input window including a consonant button, a vowel button, and a conversion button for the consonant or vowel. In the present invention, the display 110 provides a user with a Korean input window and at the same time serves to display a state in which the input characters are combined, and at the same time plays a role of receiving Korean input from the user through the Korean input window. Can be done.

For example, as shown in FIG. 2, the consonant button corresponding to 'B', 'B', 'c', 'ㅂ', 'ㅅ', 'ㅇ', and 'ㅈ', and 'ㅣ' A Korean input window including a vowel button corresponding to ',' ㅕ ',' ㅑ ',' ㅡ ',' ㅛ ',' ㅠ ', and a conversion button for the consonant and the vowel can be displayed. Here, the function of the conversion button for the consonants and vowels is, for example, when the first button is a consonant or a vowel button, when the conversion button is touched by a second button, corresponding to the character or the vowels corresponding to the consonant It means a function that can be converted according to the function of the preset second button.

In one embodiment, the display unit may display the Hangul input window in a touch screen or g-speak (g-speak) method. Here, the G-Speak method means that the Korean actor Tom Cruise displays the Hangul input window so that the Hangul may be input by the data glove used in the movie called "Minority Report." In addition, in the G-speak method, the data glove refers to a device in which a sensor is mounted in the glove, and the mounted sensor detects this and inputs information into a computer.

The display unit may differently display the arrangement of the consonant button, the vowel button, and the conversion button for the consonant or the vowel included in the Hangul input window according to a user's setting. In other words, the Hangul input system according to the present invention may display the Hangul input window of various methods according to the user's setting in addition to the Hangul input window shown in FIG. 2. For example, among the vowel buttons shown in FIG. 2, only the vowel buttons corresponding to ㅡ and ㅣ may be displayed in the Korean input window according to the user's setting.

The display unit may differently display the size of the second button that can be combined with the first button and the size of the second button that cannot be combined with the first button among the buttons included in the displayed Korean input window. For example, since the text input starts from the consonant, when the consonant button is touched by the first button, among the buttons included in the Korean input window, the size of the second button that can be combined with the first button is determined by the first button. The display may be larger than the size of the second button which cannot be combined with the button. In other words, uncombined characters can be reduced in size, and buttons that can be combined increase in size to facilitate character input.

The control unit 120 serves to combine or convert the characters input through the Hangul input window provided to the user by the display 110, for this purpose, the drag determination unit 121, the conversion button The determination unit 123, the character conversion unit 125, the character combination completion unit 127, and the character combination unit 129 are included.

The drag determination unit 121 determines whether the second button is touched by dragging the first button among the buttons included in the Hangul input window displayed by the display 110. In the present invention, the drag means an action of moving between buttons during text input, and for example, dragging without moving a finger while the first button is pressed with a finger to move to the second button. do. This means that the Hangul input system according to the present invention may continuously input characters when the second button is dragged and touched while the first button is touched, and if the touch state is released, the character combination is completed. Because.

When it is determined that the second button is touched by dragging, the conversion button determining unit 123 determines whether the second button is a conversion button, and the character conversion unit 125 determines that the second button is a conversion button. If it is determined, the character corresponding to the first button is converted according to the function of the preset conversion button.

In one embodiment, the character conversion unit 125 is any one of the buttons corresponding to the first button 'b', 'c', 'ㅂ', 'ㅈ', 'ㅇ', the conversion button If it is determined by the determination unit 123 that the second button is the conversion button, the character corresponding to the first button is replaced by 'ㅋ', 'ㅌ', 'ㄷ', 'ㅊ', 'ㅎ'. Can be converted to the corresponding character. In other words, when the first button is the consonant button and the second button is the conversion button, the character conversion unit converts a character corresponding to the consonant button which is the first button according to the function of the preset conversion button.

In one embodiment, the character conversion unit 125 is the button corresponding to the first button '-', and the conversion button determination unit 123 determines that the second button is the conversion button In this case, when the conversion button is touched in the downward direction, the letter corresponding to 'ㅡ' is converted into a letter corresponding to 'ㅗ'. It can be converted to the character corresponding to 'TT'.

For example, when the first button is a button corresponding to 'ㅡ', when the touch is dragged from the downward direction to the conversion button, the character converter changes the character corresponding to 'ㅡ' to 'ㅗ' and moves upwards. When dragged to the conversion button in, it converts to the character corresponding to 'TT'. On the other hand, when the first button is' ㅡ ', when the conversion button is continuously dragged and touched according to the function of the preset conversion button is converted in the order' TT, ㅠ, TT, ㅡ 'or' ㅗ, ㅛ, ㅗ, Can be converted to the '-' order.

In another exemplary embodiment, the character conversion unit 125 is a button corresponding to the first button '-', and the conversion button determination unit 123 determines that the second button is the conversion button. In this case, when the conversion button is dragged downwards, the letter corresponding to 'ㅡ' is converted into a letter corresponding to 'TT', and when the conversion button is dragged upwards, the ' A character corresponding to ㅡ can be converted into a character corresponding to 'ㅗ'.

In one embodiment, the character conversion unit 125 is the button corresponding to the first button '|', and the conversion button determination unit 123 determines that the second button is the conversion button In this case, when the conversion button is dragged in the left direction, the character corresponding to 'ㅣ' is converted into a letter corresponding to 'ㅓ', and when the conversion button is dragged in the right direction while being touched, the ' The character corresponding to ㅣ 'can be converted into the character corresponding to' ㅏ '.

For example, when the first button is a button corresponding to 'ㅣ', if the conversion button is touched and dragged to the left, the character converter changes the character corresponding to 'ㅣ' to '로', When the conversion button is dragged in the right direction while being touched, the conversion button converts the character to 'ㅏ'. Meanwhile, when the first button is 'ㅣ', when the conversion button is continuously dragged and touched, the first button is converted into 'ㅏ, ㅑ, ㅏ, ㅣ' or 'ㅓ, ㅕ, ㅓ,' according to the function of the preset conversion button. Can be converted into an order.

In another exemplary embodiment, the character conversion unit 125 is a button corresponding to the first button 'ㅣ', and the conversion button determination unit 123 determines that the second button is the conversion button. In this case, when the conversion button is dragged and touched in the left direction, the character corresponding to 'ㅣ' is converted into a character corresponding to 'ㅓ', and when the conversion button is dragged and touched in the right direction, it corresponds to 'ㅣ'. Character can be converted to the character corresponding to 'ㅏ'.

If it is determined by the drag determination unit 121 that the second button is dragged and not touched, the character combination completion unit 127 completes the character combination up to the character corresponding to the first button. For example, if you press the button corresponding to 'ㄱ' with your finger and move it to the position of 'ㅑ' without releasing your finger, 'Ga' is entered. Subsequently, when the finger is moved over the conversion button, it is converted to 'ga', and when the finger is finally released, that is, when it is determined that the finger is not touched by dragging, the input of the letter 'ga' is completed.

The character combination unit 129 combines a character corresponding to the first button and a character corresponding to the second button when the conversion button determining unit 123 determines that the second button is not a conversion button. do.

In one embodiment, the character combination unit 129 is a button corresponding to the first button 'b', the second button is a button corresponding to 'c' or 'b', the first A letter corresponding to the button and a letter corresponding to the second button may be combined into a letter corresponding to 'ㄹ' or 'ㅁ'. In other words, the Hangul input system according to the present invention can combine characters between different consonants that cannot be combined in existing mobile phones.

In one embodiment, the letter combination unit 129 is a button corresponding to the first button 'a', 'c', 'ㅂ', 'ㅅ', 'ㅈ', the second button is the When the first button is the same, the letter corresponding to the first button and the letter corresponding to the second button are combined into letters corresponding to 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ' and 'ㅉ'. can do. That is, when the first button and the second button are the same button as a specific consonant button, the letter combination unit may combine a letter corresponding to the first button and a letter corresponding to the second button into a letter corresponding to the old sound.
