In general, a touch screen provides an interface for a user to input a command or information to a terminal by touching an icon displayed on the screen using a finger or a pointing device. Here, the touch screen is a kind of input device, and has recently been applied to various terminals such as a mobile phone, a smart phone, an unmanned cash dispenser, a Palm PC, and a personal digital assistant (PDA).

Character input through the touch screen is largely divided into a handwriting input method and a soft keyboard input method. In the handwriting input method, a character is input by writing a letter with a stylus pen on a screen as if writing a pen on a paper. In the soft keyboard input method, a small virtual keyboard having a user interface in the form of a general keyboard is displayed on a screen to input characters by pen click.

On the other hand, with the recent trend toward smaller and lighter terminals, the size of the touch screen has to be smaller and lighter. Accordingly, in the soft keyboard input method, a plurality of characters are assigned to each key button on the virtual keyboard displayed on the screen, and a predetermined letter is selected and input according to the number of touch downs of each key button. do. Therefore, when a character is input using the soft keyboard input method, a plurality of key button touchdowns are required even if one consonant or a vowel is input. This not only makes the user feel uncomfortable, but also causes a waste of time.

An object of the present invention is to provide an apparatus and method for inputting a character in a device using a touch screen.

An object of the present invention is to provide an apparatus and method for inputting a plurality of characters through a single touch down in a device using a touch screen.

An object of the present invention is to place a plurality of key buttons, one letter is arranged on each key button on the virtual keyboard of the Hangul input mode in a device using a touch screen, and to touch down (drag) and drag ( The present invention provides an apparatus and a method for recognizing and inputting initial, neutral, and final characters of Hangul by changing a direction of a drag and a touch up.

By automatically recognizing and entering the tense of the Be verb with the directionality of the touch down and drag of the Be verb key button, a plurality of characters can be input through one touch down. This reduces the number of key button touchdowns compared to the conventional method and enables easier and faster character input.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that the specific description of the related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

Hereinafter, an apparatus and method for inputting a plurality of characters through a single touchdown in a device using a touch screen will be described.

1 is a block diagram showing an apparatus configuration of a device using a touch screen according to the present invention.

As shown, the device using the touch screen includes a control unit 100, a storage unit 102, an input unit 104, and a display unit 106.

Referring to FIG. 1, a control unit (MPU: Micro-Processor Unit) 100 controls the overall operation of the device, and processes a function for inputting a plurality of characters through one touchdown according to the present invention. .

The storage unit 102 stores microcodes and various reference data of programs for processing and control of the controller 100, temporary data generated during execution of various programs, and various kinds of updatable storage data. In particular, according to the present invention stores a program for inputting a plurality of characters through one touch down.

The input unit 104 includes numeric key buttons and a plurality of function key buttons, and provides the controller 100 with key button input data corresponding to the key button pressed by the user.

The display unit 106 displays status information generated during the operation of the device, a limited number of characters, a large amount of moving images and still images, and the like. In addition to the usual functions, the display unit 106 displays the virtual keyboard in the character input mode.

Hereinafter, the present invention will be described with reference to FIGS. 2 through 3 to input a single letter consisting of a consonant, a neutral, and a consonant through a single touchdown in inputting Korean characters in a device using a touch screen. Let's do it.

2 is a diagram illustrating a virtual keyboard form of the Hangul input mode and a Hangul input method using the same in a device using a touch screen according to an embodiment of the present invention. Here, the size, shape, and arrangement of the virtual keyboard may be variously configured according to convenience.

Referring to FIG. 2, a plurality of key buttons in which one letter is disposed on each key button is arranged on a virtual keyboard of the Korean input mode. In this case, the key buttons arranged with the consonants of Hangul and the key buttons arranged with the vowels may be disposed on the virtual keyboard by dividing them into upper and lower parts, respectively.

Here, the device may recognize the initial, neutral, and finality of the Hangul by changing the direction of touch down and drag of the key buttons on the virtual keyboard and touch up. That is, the device may recognize a character arranged on the corresponding key button where the touchdown occurs as the first Korean letter. In addition, when a drag occurs while the touch down occurs and the direction of the drag is changed, the device may recognize a character disposed on a corresponding key button of a vertex in which the direction of the drag is changed as the neutral of Korean. . Lastly, when touch-up occurs in the state in which the drag occurs, or touch-up occurs in a state in which the direction of the drag is changed, the device may recognize the character disposed on the corresponding key button as the finality.

For example, when the letter 'Samsung' is input, as shown in (a) of FIG. 2, it is possible to input by two touches. That is, the user may input one letter through one touch. First, a user performs a touchdown on a key button on which 'ㅅ' is arranged for inputting '3'. In this case, the device recognizes the letter 'g' as the initial of the letter to be input by the user, thereby detecting that a touch for inputting one letter is started. In this state, the user moves a straight line from the key button on which the '배치' is disposed to a key button on which the neutral 'ㅏ' is disposed by dragging, and again the 'ㅁ' on the key button on which the 'ㅏ' is placed 'Will move in a straight line to the placed key button. In this case, the device recognizes the 'ㅏ' disposed on the corresponding key button of the vertex in which the direction of the drag is changed as the neutral of the letter to be input by the user. Thereafter, the user performs a touch up on the key button where 'ㅁ' is arranged. In this case, the device recognizes 'ㅁ' as the finality of the character that the user wants to input, thereby detecting that the touch for one character input is completed. In the same way, the user can enter the letters of the last name.

Here, when using a finger or a touch pen, it is not easy to move perfectly in a straight line as shown in FIG. Therefore, as shown in (b) of FIG. 2, the device generates an imaginary vector line connecting the point where the touch starts and the vertex in which the direction of the drag changes, and between the point and the point where the touch ends. By displaying, the user can recognize the desired key button. Here, the vertex in which the direction of the drag is changed can be easily detected by changing the X and Y coordinates of the vector line.

3 is a flowchart illustrating a method for inputting Korean characters in a device using a touch screen according to an embodiment of the present invention.

Referring to FIG. 3, in operation 301, the device determines whether the user enters a text input mode according to a user's key manipulation, for example, selecting a text input menu. When entering the text input mode, in step 303, the device displays a virtual keyboard in which one letter is disposed on each key button, as shown in FIG.

In operation 305, the device determines whether a touch down event occurs. When the touch down event occurs, the device recognizes and inputs the letter disposed on the corresponding key button as the initial of the letter in step 307, and displays the input letter on the screen.

In operation 309, the device determines whether a drag event occurs in a state where the touch down event occurs. When the drag event does not occur, the device terminates the algorithm according to the present invention.

In contrast, when the drag event occurs, the device determines whether the drag direction is changed in step 311. If the direction of the drag does not change, the device proceeds directly to step 315. On the other hand, when the drag direction is changed, the device recognizes and inputs the character disposed on the corresponding key button of the vertex of which the drag direction is changed as the neutral of the corresponding character in step 313, and inputs the input character on the screen. Display.

Thereafter, the device checks whether a touch up event occurs in step 315. When the touch up event does not occur, the device returns to step 311 and repeats the following steps. In contrast, when the touch-up event occurs, the device recognizes and inputs the character disposed on the corresponding key button as the finality of the corresponding character in step 317, and displays the input character on the screen.

The device then terminates the algorithm according to the invention.

As described above, in the case of Hangul, there is an initial consonant, a neutral, and a final consonant, and through one touchdown, one letter input consisting of the initial consonant, the neutral, and the final consonant is possible. That is, a plurality of characters can be input through one touch down. However, in the case of English, there is no initial, neutral, or finality as in Korean, and therefore, it is impossible to apply the virtual keyboard form as shown in FIGS. 2 to 3 and the Korean input method using the same.

On the other hand, Be verbs occupy a high proportion in terms of usage, and the number of characters to be input one by one is greatly increased according to the tense. Therefore, in the present invention, a method for inputting Be verbs requiring a plurality of characters in a single touchdown in inputting English characters in a device using a touch screen is described with reference to FIGS. 4 to 6. Shall be. In particular, it will be described how to easily enter the Be verb in consideration of the tense.

4 is an exemplary diagram illustrating a virtual keyboard form of an English input mode including a Be verb key button in a device using a touch screen according to an embodiment of the present invention. Here, the size, shape, and arrangement of the virtual keyboard may be variously configured according to convenience.

Referring to FIG. 4, a plurality of key buttons including a key button 400 for inputting a Be verb are arranged on a virtual keyboard of an English input mode.

Here, the tense of the Be verb may be recognized as a touch down and drag direction with respect to the Be verb key button 500 as shown in FIG. 5. That is, in the tense of Be verbs, the present tense can be recognized as a single touchdown on the Be verb key button 500, and the present perfect type is a single touchdown on the Be verb key button 500 and a long touch on it. It can be recognized as a long press. In addition, in the tense of the Be verb, the future complete type can be recognized by one touch down and dragging upwards on the Be verb key button 500, and the past complete type can be recognized by the Be verb key button 500. It can be recognized by one touchdown and dragging downward. Also, in the tense of Be verbs, the past tense can be recognized by one touch down on the Be verb key button 500 and dragging in the left direction, and the future tense by one touch down on the Be verb key button 500. Can be recognized by dragging in the right direction.

For example, "I am a student", "I was a student", "I will be a student", "I have been a student", "I had been a student", "I will have been a student" In the case of inputting each of the modal verbs and the Be verb part in each sentence, the Be verb key button 500 can be automatically input by dragging with touch and direction.

am (current): One touch down on Be verb keybutton (Short Press)

-was (historical): single touch down on the Be verb keybutton and drag to the left

-will be (future type): single touch down on the Be verb keybutton and drag to the right

have been (currently complete): Long press after a single touchdown on the Be verb keybutton

had been (historical): drag down on the Be verb keybutton after one touchdown

-will have been (future-completed): Touch up on Be verb key button and drag upward

In this way, Be verbs automatically input are automatically selected Be verbs such as am, are, and is according to the subject's first person and singular / plural, and the tense is input by directional dragging. To this end, there may be a mapping table of Be verbs according to the first person and the singular / plural of the subject in the storage. That is, the device confirms the subject's first person and singular / plural through the word already inputted before the touch down on the Be verb key button 500, and in the mapping table, the device's first person and singular / plural Extracts the Be verb and converts the extracted Be verb into a tense according to the drag direction.

6 is a flowchart illustrating a method for inputting English characters in a device using a touch screen according to an embodiment of the present invention.

Referring to FIG. 6, in operation 601, the device determines whether the user enters a text input mode according to a user's key manipulation, for example, selecting a text input menu. When entering the text input mode, the device displays a virtual keyboard on which a plurality of key buttons are arranged, including a Be verb key button, as shown in FIG. 4 in step 603.

In operation 605, the device determines whether a touch down event occurs for the Be verb key button. When no touch down event occurs for the Be verb key button, the device performs a normal function. On the other hand, when a touch down event occurs for the Be verb key button, the device determines whether a drag event occurs in the up / down / left / right directions in step 607.

When the drag event occurs in the upward direction in step 607, the device recognizes the tense of the Be verb as the future complete in step 609, inputs the future completed Be verb, and displays the input future completed Be verb. Display on. In addition, when the drag event occurs in the downward direction, the device recognizes the tense of the Be verb as past completed in step 611, inputs the past completed Be verb, and displays the input past completed Be verb on the screen. When the drag event occurs in the left direction, in step 613, the tense of the Be verb is recognized as the past tense, the past Be verb is input, and the past Be verb is displayed on the screen. When the drag event occurs in the right direction, the device recognizes the tense of the Be verb as the future type in step 615, inputs the future Be verb, and displays the input future Be verb on the screen.

In contrast, when the drag event does not occur in the up / down / left / right directions in step 607, the device checks whether a long press event occurs in step 617. That is, it is checked whether a time equal to or greater than a threshold time elapses while the touch down event occurs. When the long press event occurs, in step 619, the device recognizes the tense of the Be verb as the current complete type, inputs the current completed Be verb, and displays the input current completed Be verb on the screen. In contrast, when the long press event does not occur, the device recognizes the tense of the Be verb as the present type in step 621, inputs the current Be verb, and displays the input current Be verb on the screen.

The device then terminates the algorithm according to the invention.
