The present invention relates to a character recognition apparatus and method, and more particularly, to a character recognition apparatus and method for recognizing a character input through a touch screen in a terminal having a touch screen.

Character input methods in a terminal using a conventional touch screen include a soft keyboard input method and a handwriting recognition method. Among them, the soft keyboard input method refers to a method in which a terminal receives a pen click by opening a keyboard-type input window on a touch screen to overcome the portability problem of a general keyboard and a mouse. In addition, the handwriting input method recognizes human handwriting (ie, handwriting) and converts it into a data code. Examples of a terminal having such a touch screen include an electronic notebook, a mobile phone, a PDA, and the like. Recently, these terminals have become smaller and lighter, and in this case, the size of the touch screen has to be smaller and lighter. As described above, the number of keys displayed on the screen for inputting the alphabet among the soft keyboard input methods in the miniaturized touch screen is 26, and all the keys for alphabet input are displayed on the miniaturized touch screen by the soft keyboard. As a result, the screen for inputting text has to be enlarged, and the area for displaying relatively output text is reduced. In addition, in the case of users who are not familiar with the alphabet, it is inconvenient because they have to input the keys while searching for the keys one by one. In addition, since the user needs to press a small button of the keyboard displayed on the touch screen which has been reduced as described above, there is an inconvenience in that the user sometimes needs to re-enter the next button. In addition, the handwriting input method of inputting characters as handwriting is not only slow input speed but also a lot of movement of the user because the user has to write the characters directly. In addition, there is a problem in that an error that frequently inputs similar characters also occurs if you do not accurately describe the characters you want to enter.

As described above, when the alphabet is input by the soft keyboard input method on the touch screen, the soft keyboard having all the keys (26) of the alphabet is displayed on the screen, so there is a problem that the space for displaying the input characters is narrow. All. In addition, a user unfamiliar with the alphabet has an uncomfortable problem of having to input the alphabet assigned to each of the 26 keys when entering the alphabet. In addition, in the case of inputting the alphabet by handwriting method, the user has to directly write a letter, so the input speed is slow, and in case of incorrect writing, a typo is frequently inputted.

Accordingly, an object and method for recognizing a character for allowing a user to enter a character more quickly and conveniently by memorizing a key of a keyboard more easily when a character is input using a soft key character input method on a touch screen is provided. In providing.

Another object of the present invention is to provide a character recognition apparatus and method for reducing the keyboard size displayed in a soft key character input method.

Still another object of the present invention is to provide a character recognition apparatus and method for more accurately inputting a character in a touch screen.

According to an aspect of the present invention, a user having at least one text input area displayed on the touch screen in a terminal having a touch screen, and a basic character and at least one extended character are assigned to the text input areas. And a controller for selecting a character according to a touch pen input type input through the character input areas and displaying the selected character.

A method of the present invention for achieving the above objects has a plurality of character input areas displayed on the touch screen in a terminal having a touch screen, a basic character and at least one extended character to the character input areas And a second process of receiving a touch pen input from a character input area through an allocated user interface, and a second process of displaying a character corresponding to the touch pen input form.

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

Hereinafter, with reference to the accompanying drawings will be described a method for quickly and conveniently entering a character when the soft key character input according to the present invention. The present invention displays two consonants of a similar type of alphabet on one key, and reduces the size of the keyboard displayed on the touch screen by allowing the vowel alphabet to be input according to a pen drag direction. In addition, the present invention forms a group of characters of a similar form so that the user can easily remember the key, so that the characters can be input by a single drag (drag) without inputting all the forms of the characters, such as handwritten input This can improve the text input speed.

First, Figure 1 is an internal configuration of a terminal having an alphabet recognition function according to the present invention. A terminal having a touch screen to which the present invention is applied includes a control unit 100, an information display unit 102, a user interface 104, and a memory 106. First, the user interface 104 outputs an input signal to the controller 100 when there is a pen stroke input by the user. In the present invention, the user interface 104 is a touch screen. The controller 100 checks an input form through a signal input through the user interface 104, and checks whether a pen click or a pen drag is made. In the present invention, a basic consonant alphabet can be input by a pen click, and an extended consonant alphabet and a vowel alphabet can be input by double clicking or dragging. Next, the soft keyboard displayed for inputting the consonant alphabet in the present invention will be described with reference to FIG. 4, which shows a soft keyboard for inputting the consonant alphabet. First, two basic characters and two extended characters, which are similar consonants, are mapped and displayed on one key of the soft keyboard. Hereinafter, each one key is defined as a character input area. In the present invention, the base letter refers to 'c, j, h, l, r, x, b, p, n, and v' among the consonants of the alphabet, and the extended letter is similar to the base letter. It refers to a character that has many strokes or two strokes in a character or basic character, and a character in which the basic character is opposite to the basic character and the form of the basic character is repeated. For example, in the basic character 'c', 's', which is a large number of characters, becomes an extended character, and the character 'd', which is the opposite of the basic character 'b', becomes an extended character, and the basic character 'n'. The repeated character 'm' becomes an extended character. In this way, the extended characters are mapped to the basic characters, respectively, and stored in the memory 106. 4, the number of soft keyboards in the present invention is twelve. Basic and extended characters are mapped one by one and assigned to one character input area. That is, the soft keyboard for inputting the alphabet into the information display unit 110 is divided into 12 character input areas and displayed.

And, as shown in Figure 4, the soft keyboard is the left and right opposite to the first extended character area 400 and the basic characters that can enter a character or a character of a similar form to the basic characters or one or two extended characters in the basic characters The second extended character area 402 capable of inputting the extended character of the form of the second character, and the third extended character area 404 capable of inputting the extended character of the repeated type of the basic character is displayed. As described above, the soft keyboard displays keys for inputting alphabetic consonants.

Next, a process for inputting the extended character and the vowel through the soft keyboard displayed as shown in FIG. 4 will now be described with reference to FIG. 5. 5 is a diagram illustrating a pen drag direction of an extended character direction for inputting an extended character and a vowel character direction for inputting a vowel alphabet according to an embodiment of the present invention. First, referring to FIG. 5, if there is a pen drag input in the directions of 500 and 502, the controller 100 recognizes the direction of the extended character for inputting the extended character in each corresponding area and displays the corresponding extended character. The control unit 100 recognizes that the input is to output the vowel alphabet 'e' when there is a pen drag input in the 504 direction, and displays 'e' on the information display unit 102. It recognizes that the input is for outputting a 'and displays' a' on the information display unit 102. The controller 100 recognizes that the input is to output the vowel alphabet 'i' when there is a pen drag input in the 508 direction, and displays 'i' on the information display unit 102. It recognizes that the input is for outputting 'y' and displays 'y' on the information display unit 102. In addition, the control unit 100 recognizes that the input is to output the vowel alphabet 'n' when there is a pen drag input in the 512 direction, and displays 'n' on the information display unit 102. Recognizing that it is an input for outputting the letter 'o', 'o' is displayed on the information display unit 102. As described above, in the case of the vowel alphabet, the vowel alphabet may be input according to different drag directions. In this case, in order to input the vowel alphabet, the vowel alphabet may be input by pen-draging in the direction of the vowel desired in the soft keyboard in any character input area. In addition, in order to reduce a recognition error when inputting a vowel alphabet, as shown in FIGS. 6A and 6B, a vowel alphabet may be input by performing a pen drag in an area where a drag direction of the vowel alphabet is displayed.

Meanwhile, FIG. 4 illustrates only a soft keyboard for inputting a consonant alphabet. In order to input a vowel, the user must recognize a drag direction as shown in FIG. 5. However, the user may not remember the drag directions for the five vowel alphabets, and thus the drag directions for the vowel alphabets may be included in the soft keyboard and displayed as shown in FIGS. 6A and 6B. 6A and 6B are diagrams illustrating a soft keyboard displayed by including a drag direction for vowel alphabet input and a drag direction for input of extended characters according to an exemplary embodiment of the present invention. The user can know the expansion direction and the vowel direction through the soft keyboard displayed as shown in Figures 6a and 6b, it is possible to conveniently enter the alphabet.

Next, a process of recognizing an alphabet input through the soft keyboard displayed as shown in FIG. 4 will now be described with reference to FIG. 2. 2 is a control flowchart for recognizing an alphabet input according to a pen click and pen drag direction according to a first embodiment of the present invention.

First, the control unit 100 maintains the standby state in step 200 and checks whether the alphabet input mode is selected in step 202. If the alphabet input mode is selected and input through the user interface 104, the control unit 100 proceeds to step 204 to check whether the pen is down. If it is detected that the pen is down, the process proceeds to step 206 and the controller 100 checks whether the pen is up after being dragged in the pen down state. If the pen is up in the pen-down state, that is, if there is a pen click, the process proceeds to step 214 to check whether the pen-down and the pen-up occur in the same character input area. In operation 216, the controller 100 displays a basic consonant alphabet assigned to the character input area. For example, in FIG. 4, if there is a pen click in the character input area displaying the basic characters 'b' and 'd' extended characters for 'b', the basic character 'b' is displayed on the information display unit 102. will be.

On the other hand, if it is recognized in step 206 that the control unit 100 drags from the pen down state and then pen up, the control unit 100 proceeds to step 208 to check the drag direction. At this time, the drag direction is 504, 506, 508, 510, 512, 514 direction for inputting the vowel alphabet as in the directions shown in FIG. 5 and the extended character direction of the first region and the extended character direction of the second region. have. In the first embodiment of the present invention, the control unit 100 recognizes that the input of the extended character is dragged in one of the extended character direction of the first region and the extended character direction of the second region, regardless of the character input region. If the pen is dragged in the direction of 500,502 which is the direction of the extended character in step 208, the controller proceeds to step 210 to display the extended consonant alphabet assigned to the corresponding character input area. For example, in step 204, after pen-downing the character input area corresponding to the basic character 'c' and dragging to the right or left, the pen character is entered with the extended character 's' in the basic character 'c'. It is recognized and display 's'.

If the pen is dragged in the directions 504, 504, 508, 510, 512, and 514, which are directions for inputting the vowel alphabet in step 208, the process proceeds to step 212 to display the vowel alphabet assigned according to the drag direction. For example, when the controller 100 recognizes that there is a pen drag input in the 506 direction, the controller 100 displays 'a'. That is, as described above, the controller 100 recognizes that the basic consonant alphabet is input by one pen click in one character input area, and drags one pen in the extended character direction 500, 502 in one character input area. Recognize that an extended consonant alphabet is entered. In addition, when dragging once in the vowel character directions 504, 506, 508, 510, 512, and 514, the vowel corresponding to the corresponding direction is input. In this case, when the vowel alphabet is input, the corresponding vowel is inputted according to the dragging direction instead of being displayed in each letter input area like the consonant alphabet, so that the keys of the soft keyboard are reduced. In addition, when inputting the collection, the control unit 100 recognizes this even if the text input area for inputting the vowel is dragged from the entire soft keyboard.

Then, as shown in FIG. 4, the first extended character area 400, the second extended character area 402, and the third extended character area 404 are respectively distinguished, and the extended character input corresponding to the characteristics in the corresponding area is inputted. A character recognition method according to the method will be described with reference to FIG. 3.

First, the first extended character area 400 is a character in a form similar to that of the basic character and is an area in which the extended character may be input by one or two strokes. Therefore, in the present invention, the user can input the extended consonant alphabet by pen dragging to the right, 502 direction. In addition, the second extended character area 402 is an area in which extended characters of opposite shapes to the basic characters can be input. Therefore, in the present invention, the user can input the extended consonant alphabet by pen dragging in the opposite direction of the basic character, that is, in the 500 direction. In addition, the third extended character area 400 is an area in which an extended character of a form in which the basic character is repeated may be input. Therefore, in the present invention, the user can input the extended consonant alphabet by double-clicking the repetition of the basic character.

3 is a control flowchart for recognizing an alphabet input according to a pen click and pen drag direction according to a second embodiment of the present invention.

First, the control unit 100 maintains the standby state in step 300 and checks whether the alphabet input mode is selected in step 302. When the alphabet input mode is selected and input through the user interface 104, the control unit 100 proceeds to step 304 to check whether the pen is down. If it is detected that the pen is down, the process proceeds to step 306 and the control unit 100 checks whether the pen is up after being pen-up or dragged in the pen-down state. If the pen is up in the pen down state, the process proceeds to step 318 to check whether there is a pen click or a double click. In this case, the process of determining the double click refers to a case in which the user clicks again within a predetermined time after the one click in step 306. If it is clicked after a preset time, it is recognized as one click. If it is recognized in step 318 that the click is made, the controller 100 proceeds to step 320 and the controller 100 displays a basic consonant alphabet assigned to the corresponding character input area. For example, in FIG. 4, when there is a single click in the character input area where the basic character is 'c', the basic character 'c' is displayed on the information display unit 102. If there is a double click in step 318, the process proceeds to step 326 to determine whether the pen down and the pen up are performed in the third extended character area. That is, double-click to check whether there is a character input in the area for inputting the extended character. If the double click is input in the third extended character area, the control unit 100 proceeds to step 314 and displays the extended consonant alphabet assigned to the corresponding character input area. For example, when there is a double click in the character input area where the basic character is 'n', 'm' which is an extended character of the basic character 'n' is displayed. However, if the pen down and the pen up are not performed in the third extended character area in step 326, that is, when there is a double-click in the first extended character area or the second extended text area, it is assigned to the corresponding character input area. Enter the basic consonant alphabet twice.

On the other hand, if it is recognized in step 306 that the control unit 100 drags in the pen-down state and then pen-up, the process proceeds to step 308 to check the drag direction. At this time, the drag directions are 504, 506, 508, 510, 512, 514 directions for entering vowel alphabets as in the directions shown in FIG. There is an extended character direction that includes an extended character direction of 500. In step 308, if the control unit 100 recognizes the extended character direction, the control unit 100 proceeds to step 324 to determine whether the extended character direction of the first area or the extended character direction of the second area. If the pen is dragged in the direction of the first extended character, the procedure proceeds to step 324. If the pen up and pen down is performed in the first extended character area, the pen up and pen down is performed in the first extended area. Displays the extended consonant alphabet assigned to the character entry area. For example, the controller 100 recognizes that the extended consonant alphabet 's' is input when the pen is dragged in the direction of the first extended character 502 in the character input area including the basic character 'c' and the extended character 's'. , displays 's'.

In operation 308, if the control unit 100 recognizes that the extended character direction is reached, the controller 100 proceeds to step 310 and determines whether the extended character direction of the first region or the extended character direction of the second region is determined. If the test result shows that the pen is dragged in the direction of the second extended character, the process proceeds to step 312. If the pen up and pen down is performed in the second extended character area, the pen up and pen down is performed in the second extended area. Displays the extended consonant alphabet assigned to the character entry area. For example, the controller 100 recognizes that the extended consonant alphabet 'd' is input when the pen is dragged in the direction 500 of the second extended character direction in the character input area including the basic character 'b' and the extended character 'd'. , displays 'd'.

Meanwhile, if the pen is dragged in the directions 504, 506, 508, 510, 512, and 514, which are directions for inputting the vowel alphabet in step 308, the flow proceeds to step 316 to display the vowel alphabet assigned according to the drag direction. For example, when the controller 100 recognizes that there is a pen drag input in the 504 direction, the controller 100 displays 'e'.

Referring to the character recognition for consonant alphabet input as described above, it is recognized that the basic consonant alphabet is input by one pen click in all the character input areas, and the direction of the first extended character in the first extended character area is 502 direction. Note that the extended consonant alphabet is entered with a single pen drag. In addition, it is recognized that the extended consonant alphabet is input by one pen drag in the direction of the second extended character within the second extended character area. In addition, it is recognized that an extended consonant alphabet is input by double-clicking in the third extended character area. In addition, when looking at the character recognition for vowel alphabet input, once dragged in the vowel direction (504, 506, 508, 510, 512, 514) at any position regardless of the specific character input area of the soft keyboard, it corresponds to the corresponding direction. Notice that the vowels are entered. In this case, when the vowel alphabet is input, the corresponding vowel is inputted according to the dragging direction instead of being displayed in each letter input area like the consonant alphabet, so that the keys of the soft keyboard are reduced.

An example for inputting the basic character and the extended character according to the characteristics of the extended character with respect to the basic character as in FIG. 3 is described with reference to FIG. 7 is a diagram illustrating a method for inputting alphabets through a soft keyboard on a touch screen according to a second embodiment of the present invention. For example, to input 'a', drag the pen in the direction of 506 in any area of the soft keyboard, and then enter 'a' when pen up. For another example, in order to input 'q', a pen may be dragged in the second extended character direction 500 in a region where the basic character is 'p'.

As described above, according to the first and second embodiments of the present invention, the number of keys of the soft keyboard displayed on the touch screen is reduced, and two consonants of a similar type are mapped to the basic consonant and the extension consonant and corresponding to each other through a pen click. Basic consonants in the text input area can be input, and extension sounds in the corresponding text input area can be input by dragging the pen. In addition, the vowel alphabet may be input by pen dragging in the direction of the vowel character regardless of the character input area, or the vowel alphabet may be input by the pen drag in the area where the drag direction for the vowel alphabet is displayed.

In addition, not only English characters but also Korean, Japanese, and French characters are divided into base character and extended character pairs in one key and assigned to the character input areas, and the pen input form is used through sentence input areas. Accordingly, one of the characters assigned to the character input area may be selected and input.

As described above, in the exemplary embodiment of the present invention, a key is divided into a base character and an extended character and is assigned to the character input areas, but some keys may be assigned only one base character or some keys. An extended character for a base character may be assigned more than one character.

Next, a method for inputting Korean on the touch screen will now be described with reference to FIGS. 8 to 10. FIG. 10 is a control flowchart for recognizing Korean characters inputted according to a pen click and a pen drag direction according to a third embodiment of the present invention. 9 is a diagram illustrating a soft keyboard screen displayed on a touch screen for inputting Korean characters according to a third embodiment of the present invention. FIG. 10 is a diagram illustrating an extended character direction for inputting an extended character, a dichotomy direction for inputting a Hangul double phoneme, and a pen drag direction for a vowel character direction for inputting a vowel Korean according to a third embodiment of the present invention. .

First, the control unit 100 maintains the standby state in step 800 and checks whether the Hangul input mode is selected in step 802. If the Hangul input mode is selected and input through the user interface 104, the control unit 100 proceeds to step 804 to check whether the pen is down. If it is detected that the pen is down, the process proceeds to step 806 and the controller 100 checks whether the pen is dragged in the pen down state. In the case of a pen-up in the pen-down state, that is, once there is a pen click, the process proceeds to step 816 to check whether the pen-down and the pen-up have occurred in the same character input area. In operation 818, the controller 100 displays a basic consonant Korean character assigned to the character input area. For example, in FIG. 8, when there is a pen click in the character input area where the basic character is 'a', the basic character 'a' is displayed on the information display unit 102.

On the other hand, if it is recognized in step 806 that the control unit 100 is dragged in the pen down state, the control proceeds to step 808 to check the drag direction. At this time, the drag direction includes 10, 12, 16, 18, 20, and 24 directions for inputting a vowel character, an extended character direction 14, and a diaphragm direction 22, as in the directions shown in FIG. If the pen is dragged in the extended character direction 14 in step 808, the flow proceeds to step 810 to display the extended consonant Korean characters assigned to the corresponding character input area. For example, in step 804, after the pen is down in the character input area to which the basic character 'ㄱ' is assigned, it is recognized that the extended character 'ㄴ' is input to the basic character 'ㄱ' to drag in the extended character direction (14). , 'B' is displayed. Thereafter, the method proceeds to step 812 and checks whether the pen is dragged up or dragged in the direction of a dichotomous character. If the phone is pen-up in the state of displaying the extended phoneme, the process proceeds to step 214 for inputting another character. Otherwise, if it is pen-up after dragging in the direction of the double phonetic character, the phonetic consonant Hangul corresponding to the displayed phonetic phoneme is displayed. For example, in the character input area where 'ㅁ' is the basic consonant and the corresponding extension sound is 'ㅂ', the pen is first penned down, dragged in the extended character direction (14), and then dragged in the double consonant direction (22) again. If so, recognize that '쌍', which is a dichotomy for 'ㅂ', is displayed, and display 'ㅃ'.

On the other hand, if the pen is dragged in the direction of the vowel character in step 808, the flow proceeds to step 822 to display the default vowel Hangul that is pre-allocated according to the drag direction. For example, when the controller 100 recognizes that there is a pen drag input in the 10 direction, the controller 100 displays 'ㅏ'. After that, the flow proceeds to step 824 to check whether the pen is dragged up while the basic vowel Korean is displayed or dragged in the direction of the expansion letter. If the default vowel Korean is displayed in the displayed state, proceed to step 804 for inputting other characters. If the default vowel is displayed, the extended vowel Korean for the displayed default vowel Korean is displayed. For example, when 'p' is displayed for a pen drag input in the 10 direction and drags back to the extended character direction, the pen is displayed with an extended vowel Hangul corresponding to 'ㅏ'.

In addition, if the pen is dragged in the direction of the double consonant in step 808, the flow proceeds to step 820 to display the consonant consonant Hangul assigned to the corresponding character input area. That is, the controller 100 recognizes that there is an input of the consonant consonant Hangul for the basic consonant Hangul, which is allocated to the pen-down character input region (804). For example, a pen down in the character input area where 'ㄱ' is the basic consonant Hangul Hangul and then pen-graphed in the direction of the double consonant letter 'ㄲ' is displayed.

That is, as described above, the basic consonant Hangul is input by one pen click in one character input area, and the extended character is recognized by dragging in the direction of the extended character in one character input area, Drag in the direction to recognize the input of double dictionaries. In addition, when inputting a vowel, a text input area for inputting a vowel is not provided separately, and the vowels are pre-assigned according to the dragging direction from the entire soft keyboard.

As described above, the present invention has the advantage of reducing the size of the keyboard by reducing the number of keys by mapping two consonants of a similar type to the basic consonant and the extension sound in a soft keyboard of the touch screen and displaying them in one character input area. . In addition, the basic consonant in the corresponding text input area can be input by clicking the pen, and the extension sound in the corresponding text input area can be input by dragging the pen. There is an advantage that you can enter the alphabet. In addition, there is an advantage that can be entered more accurately when entering a character on the touch screen.
