It is a cross section. 7 is a plan view showing a protective film of the character input system according to the present invention.

As shown in FIG. 1, the character input system according to the present invention includes a touch screen module 100, a keyboard module 200, an input processing module 300, a processing module 400, and a speaker 500. It includes.

The touch screen module 100 is for inputting a character by directly touching a user, and includes a touch panel. These touch panels are capacitive overlay, resistive overlay, infrared beam, surface acoustic wave, and integral tension measurement depending on the structure and driving method. Methods (Integral Strain Guage), Piezo-Effective method (Piezo Electric) and the like. Of course, the present invention can use any touch panel regardless of the type for the user to enter characters.

The keyboard module 200 is for visually recognizing a keyboard to a user. The keyboard module 200 is provided at a lower portion of the touch module, and when the user touches the keyboard to input a character, the touch screen module 100 corresponding to the position of the character is touched. Is input. As shown in FIG. 2, the keyboard module 200 expands the size of the arranged keyboard module 200 to reduce a typographical error by inputting the letters ㄱ, ㅁ, ㅅ, ㅇ, and ㅣ. It can be implemented as six buttons including ',' ㅡ '. Of course, although the keyboard is arranged in a matrix form in FIG. 2, the layout of the keyboard may vary depending on the device to which the character input system according to the present invention is applied. In addition, although the present invention exemplifies the keyboard module 200 having the above six buttons, if the eight-way input operation proposed in the present invention is applied, the size of the keyboard module 200, that is, the keyboard module 200 is applied. Buttons provided on the size thereof and may be provided in various ways.

In addition, in the keyboard module 200 illustrated in FIG. 2, a 'SPACE' key and a 'language setting' key for changing a character of a keyboard such as Korean, English, and Japanese may be added. In addition, the keyboard module 200 described above may input at least three or more characters into one key according to a user's input operation.

Table 1 shows the character input according to the input operation of the character input system according to the present invention.

Basic keyboard A M S ㅇ ㅣ ㅡ Touch A M S ㅇ ㅣ ㅡ Sang Drag N ㅂ H ㅎ ㅗ Hard Drag ㄲ ㅃ ㅆ ㅎ ㅜ Left drag C D ㅈ Lol ㅓ Udrag ㄸ ㅍ ㅉ ㅌ A

Referring to Table 1, as an example, in the case of 'a', 'a' is input when performing a touch, and 'b' is input when performing a phase drag operation. In addition, 'h' is input when the lower drag operation is performed, and 'c' is input when the left drag operation is performed. In addition, 'ㄸ' is input when the right drag operation is performed. Of course, Table 1 is only one example, and the user's input operation such as the upper drag and the lower drag for a specific key may be changed.

The input processing module 300 classifies an input through the keyboard module 200 and the touch screen module 100 into touch, drag, multi-touch, and multi-touch drag, and classifies the location information and the classification information into the processing module 400. To pass. The input processing module 300 includes a touch determination module 320 and an input correction module 340.

The touch determination module 320 is for determining that the user touches the touch screen module 100. The touch determination module 320 may include a touch module 322, a drag module 324, a multi-touch module 326, and a multi-touch drag module. 328.

The touch module 322 detects a point where a user starts a touch on the touch screen module 100.

The drag module 324 detects a point at which the user ends the touch on the touch screen module 100, and uses a drag performed by the user by using the detected touch end point and a point at which the touch module 322 starts the detected touch. Recognize the action. Since the user must perform the touch first by applying pressure to the touch screen module 100 even if the user wants to perform a drag for inputting the character, the drag module 324 may perform the touch start point detected by the touch screen module 100. After receiving the information, it adds information about the touch end point detected by the user to finally recognize the drag operation.

The multi-touch module 326 detects that a user simultaneously touches two or more points on the touch screen module 100.

The multi-touch drag module 328 simultaneously touches two or more points on the touch screen module 100, and then detects the drag movement while maintaining the touched state. To this end, the multi-touch drag module 328 recognizes the user's multi-touch drag operation by using a touch end point for two or more points and a touch start point for the multi-touch detected by the multi-touch module 326. Of course, the present invention may perform only a general touch operation and a drag operation. In this case, the above-described multi-touch module 326 and the multi-touch drag module 328 may be omitted.

In addition, the present invention, as shown in Figure 3, the touch input operation for all the keys and the left drag (①), the right drag (②), the upper drag (③), the lower drag (④), the lower left drag (⑤) 8 inputs including the upper left drag (⑥), the upper right drag (⑦), and the lower right drag (⑧) are possible. For example, in the case of the 'SPACE' key, if a touch operation is performed, it operates as a general blank key. In addition, when the left drag (①) operation is performed as the 'backspace key', and the right drag (②) operation can be operated as the 'enter key'. Of course, this is only one embodiment, the 'SPACE' key according to the present invention operates as the 'backspace key' when performing the upper drag (③) operation, 'enter key' when performing the lower drag (④) operation It can also work.

Meanwhile, the present embodiment exemplifies only Korean input, but the character input system according to the present invention may input a foreign language such as English. For example, when entering English through language setting, it may also be input in a similar manner to the above-described Korean input method. That is, one or more alphabets may be input from a specific alphabet key by touching or dragging a specific alphabet key in a specific direction.

The input correction module 340 is for correcting an operation input by the user through the touch screen module 100, and includes an input angle correction module 342, an input length correction module 344, and an input time correction module 346. , And input order correction module 348.

The input angle correction module 342 is for correcting the angle of the drag operation input by the user through the touch screen module 100. As shown in FIG. 4, the upper and lower drags are input along the y-axis, and the left and right drags are input along the x-axis. However, the user may not input correctly in the vertical direction (up and down drag) or the horizontal direction (left and right drag) when the drag is input. Therefore, the present invention includes an input angle correction module 342 to calculate the error range when the user inputs the drag so that the input is correctly recognized. Referring to FIG. 4, in the present invention, the drag input within the first angle θ ₁ is recognized as a left and right drag, and the drag input within the second angle θ ₂ is recognized as an up and down drag. In this case, the first angle θ ₁ and the second angle θ ₂ may be, for example, 0 degrees to 25 degrees. However, the present invention is not limited thereto, and the first angle θ ₁ and the second angle θ ₂ may be 0 degrees to 45 degrees. In addition, the input angle correction module 342 may learn this according to the input characteristic of the user. Accordingly, the first angle θ ₁ and the second angle θ ₂ may be different from each other. For example, as shown in FIG. 5, for example, when a user inputs a character with both hands, the left and right hands have different input angles A from each other. In this case, the reference coordinate axes (the x-axis and the y-axis of FIG. 4) are corrected to fit the input characteristics of the user according to the angle mainly dragged by the user. It updates the angle of the finger input by the user, that is, the dragging angle, every time to correct the most ideal angle corresponding to the user's input characteristics. In addition, according to the present invention, the character input system may narrow the first angle θ1 and the second angle θ2 to match the input characteristics of the user, and may simplify the calculation process to increase the text input speed. Can be.

The input length correction module 344 is for correcting the length of the drag operation input by the user through the touch screen module 100. This may be determined according to the number of pixels P of the touch screen module 100 that are touched through the drag operation, as shown in FIG. 6. For example, a drag input having a first length L ₁ or less may be recognized as a touch, and a drag input having a first length L ₁ or more, that is, a second length L ₂ may be recognized as a drag. In addition, according to this, the text input system according to the present invention can increase the accuracy of the text input by preventing the drag operation unintended by the user.

The input time correction module 346 is for correcting the delay time of the drag operation or the delay time of the touch operation input by the user through the touch screen module 100. The present invention may generate an event when the user delays the touch without stopping the drag operation, and the input time correction module 346 determines whether the event occurs. For example, the delay time correction of the drag operation may be repeatedly performed automatically when the user holds the touch for 0.5 seconds or more after the drag operation. In addition, the delay time correction of the touch operation is determined as a double touch (double click) when the user touches the specific key again after 0.5 seconds after the touch operation on the specific key. At this time, if the user touches the specific key again within 0.5 seconds after performing the touch operation on the specific key, it is regarded as one touch operation.

The input order correction module 348 is for correcting a character input order error of the user. For example, in order to enter 'A', 'ㄱ' and 'ㅏ' must be entered sequentially. However, when entering the sentence 'ㄱ' and 'ㅏ' can not be entered sequentially, 'ㅏ' and 'ㄱ' may be entered in the order. In this case, the present invention is not input as 'ㅏ a', and stores the input 'ㅏ' and 'ㄱ' and then displays 'A'.

The processing module 400 merges the characters sensed by the input processing module 300 and transmits the image signals to the display module (not shown) for visual recognition of the characters to the user so that the user can recognize the characters input by the user. do. In addition, an acoustic signal for this, for example, a beep sound according to the character input is transmitted to the speaker 500 so that the user can hear it.

The speaker 500 reproduces an audio signal transmitted from the processing module 400 so that the user can hear it. Of course, the speaker 500 may be omitted, but it is basically provided to the device, for example, a mobile phone, PDA, etc. to which the character input system according to the present invention can be applied.

Meanwhile, the present invention may further include a motor 600 that recognizes that the user is touched when the user touches the touch screen module. In this case, the motor 600 may include a vibration motor, and when the user touches the touch screen module by the motor 600, the motor 600 may recognize the button pressed by the vibration.

The invention also includes a memory for storing characters in which the user has made an input operation. When a user simultaneously inputs two letters, that is, consonants and vowels, it is not known whether the user first touches an input character is the last input character or takes an input operation such as a drag after the first touch input operation. Therefore, since all input operations of the user start with the touch input operation, they are stored in the memory until the final input character is determined. For example, if the user presses the first letter 'ㄱ' and then press 'ㅣ' as the second character, the first letter is entered as 'ㄱ' through the touch input operation or 'd' through the drag input operation. 'Is input or not selected. In this case, 'ㄱ' and 'ㅣ' are stored in memory instead of the letters 'ㄱ' and 'ㅣ'. At this time, when 'ㄱ' is selected as the first character, 'AB' is loaded and displayed in the memory. Otherwise, 'ㅋ' is immediately displayed when 'ㅋ' is selected through the drag input operation. After that, if 'ㅣ' is selected as a vowel, 'ㅣ' is loaded from memory and finally 'GI' is displayed. Otherwise, if '경우' is selected as the second character through the drag input operation, 'ga' is finally displayed.

In addition, the character input system according to the present invention, as shown in Figure 7, a keyboard that allows the user to sense the sense of the fingertips even if the user does not see the position of the character key (K) provided in the keyboard module 200 It may further include a guide. The keyboard guide may be in the form of a general protective film, and includes protrusions protruding at the central position of the letter key K on the surface of the protective film. In this case, the protective film and the protrusion is preferably made of a transparent material such as rubber or silicon. That is, the present invention may be provided with a keyboard guide made of a transparent material which is very small to the naked eye in the center of the letter key K and does not interfere with the user's visual recognition. In addition, according to the present invention, even if the user does not see the keyboard module 200 directly, the user may input characters.

As described above, the character input system according to the present invention can correct the user's input even if there is an error, so that the user can correctly input the character to be input. In addition, the character input system according to the present invention supports a touch input operation and an 8-direction input operation on one key, so that up to 18 characters including multi-touch may be input on one key. In addition, the character input system according to the present invention supports the input operation of up to 8 directions including the touch input operation and the multi-touch in the 'SPACE' key, so that the 'SPACE' key is 'Backspace' and 'Space' according to the input operation. The operation of the 'key and the' enter 'key can be performed.

Next, a character input method according to the present invention will be described with reference to the drawings. Descriptions overlapping with the description of the character input system according to the present invention will be omitted or briefly described.

8 is a flowchart of a character input method according to the present invention.

As shown in FIG. 8, the character input method according to the present invention includes setting a language (S ₁ ), detecting an input (S ₂ ), correcting an input (S ₃ ), and Classifying (S ₄ ) and merging characters (S ₅ ).

In the setting of the language (S ₁ ), the language is set according to the type of language to be input by the user. This embodiment exemplifies inputting Korean or English through language setting. Of course, the present invention is not limited thereto and may be applied to all languages other than Korean and English. On the other hand, if only one language is used in the system to which the character input method according to the present invention is applied, the step (S ₁ ) of setting the aforementioned language may be omitted.

Detecting an input (S ₂ ) detects a user's touch screen module input for inputting a character. In this case, the present invention includes the steps of the user and because the input by separating the character input in such a touch and drag, the method comprising: detecting the input to recognize correctly the user of the character input (S ₂₎ is detected the starting position of the touch (S _{2 -1} ), storing the character of the touch start position (S _2-2 ), and sensing the end position of the touch (S _2-3 ).

In the detecting of the starting position of the touch (S _2-1 ), the starting position of the first touch by the user to the touch screen module for text input is detected. In this case, as the first position of the touch is detected, the first consonant or vowel that is not deformed by the user's input character, that is, the drag or the multi-touch drag, may be known. Also, in the step of detecting the start position of the touch, in order to collect touch type information, the user detects whether the user touches only one point of the touch screen module or touches two or more points at the same time, that is, multi-touch.

In operation S _2-2 , the character at the touch start position is stored in the character in which the user performs a touch input operation on the touch screen module. This means that when a user enters two letters, ie, consonants and vowels at the same time, the user does not know whether the first touch input action is the last input character or whether the user takes an input action such as a drag after the first touch input action. . Therefore, since all input operations of the user start with the touch input operation, they are stored in the memory until the final input character is determined. For example, if the user presses the first letter 'ㄱ' and then press 'ㅣ' as the second character, the first letter is entered as 'ㄱ' through the touch input operation or 'd' through the drag input operation. 'Is input or not selected. In this case, 'ㄱ' and 'ㅣ' are stored in memory instead of the letters 'ㄱ' and 'ㅣ'.

In the detecting of the end position of the touch (S _2-3 ), after the user touches the initial sound, the touch end position of the last touch is sensed. The user may drag or multi-drag horizontally, vertically or diagonally at an initial position to input a desired character. Accordingly, the terminal senses a position at which the user ends the touch in order to acquire information about the final sound of the character to be finally input, that is, the consonant or vowel to be finally input by the drag or multi-touch drag.

Correcting the input (S ₃ ) corrects the input operation of the user input through the sensing (S ₂ ) of the input. Correcting the input (S ₃ ) comprises the step of correcting the input angle (S _3-1 ), the step of correcting the input length (S _3-2 ), and the step of correcting the input time (S _3-3 And correcting the input order (S _3-4 ).

Correcting the input angle (S _3-1 ) corrects an input angle error of the user when the user performs a drag operation or a multi-touch drag operation. It is based on the x-axis and the y-axis that intersects the x-axis vertically, and drag or multi-drag drag motions that are close to the x- or y-axis within a range of angles on the x- and y-axes. Consider it as a touch drag operation. This means, for example, that a drag motion in an angular range close to the x axis is classified as an upper drag or a lower drag according to the drag direction, and a drag motion in an angular range close to the y axis is classified as a left drag or a right drag according to the drag direction. .

Correcting the input length (S _3-2 ) corrects an input length error of the user when the user performs a drag operation or a multi-touch drag operation. The device recognizes a drag operation or a multi-touch drag operation within a certain number of pixels according to the number of pixels of the touch screen module as a touch, and a drag operation or a multi-touch drag operation of a predetermined number or more is determined as a corresponding drag operation or a multi-touch drag operation. Can be done.

Correcting the input time (S _3-3 ) corrects an input time error of the user when the user performs a touch operation, a multi-touch operation, a drag operation, or a multi-touch drag operation. At this time, the step of correcting the delay time of the drag operation during the step (S _3-3 ) of correcting the input time is to stop the touch after a delay within a certain time without stopping the touch after the drag operation or multi-touch drag operation It may be determined by a general touch operation. Of course, if a delay is delayed for a predetermined time without stopping the touch after the drag operation or the multi-touch drag operation, an event such as a repeated input may be generated. In addition, the step of correcting the delay time of the touch operation during the step of correcting the input time (S _3-3 ), if the user touches the specific key again within a certain time after the touch operation on the specific key, This can be done by considering the input of. Of course, if the user touches the specific key again after a certain time after performing a touch operation on the specific key, it is determined as two inputs (double clicks).

Correcting the input order (S _3-4 ), when a user inputs a character, corrects a mistake in the character input order. This is because when the user inputs a letter in the wrong order, that is, when the vowel and consonant are reversed in the Hangul input, the corresponding consonant and the vowel are saved and rearranged. Can be done by expression.

In step S ₄ , the input is classified according to the touch start position information, the touch end position information, and the touch type information (touch or multi-touch) obtained by detecting the start position and the end position of the touch. . In addition, according to this classification, the user's input is a touch that presses only one point of the touch module, a drag moved while pressing from one point of the touch module to another point, and a multi-touch that presses two or more points of the touch module simultaneously. The multi-touch drag may be classified as a multi-touch drag that moves to a specific point while simultaneously pressing two or more points of the touch module.

In the merging of the characters (S ₅ ), the characters are merged according to the acquired touch start position information, touch end position information and touch type information, and the input classified accordingly, and displayed to the user. This embodiment exemplifies a language input through a character input method in Korean and English. Accordingly, in the merging of characters, the consonants and vowels for the Korean characters are stored in a buffer according to the language set in the language setting step. Merging the alphabet with step S _5-1-1 , merging consonants and vowels (S _5-1-2 ), or storing alphabets for English (S _5-2-1 ); S _5-2-2 ).

Storing the consonants and vowels in the buffer (S _5-1-1 ) may be performed before merging the consonants and vowels finally determined according to the acquired touch start position information, touch end position information and touch type information, and the classified input accordingly. Store in a buffer. This means that if the user's input consonants and vowels are listed or combined in the order entered by the user, normal characters cannot be implemented. Therefore, the consonants and vowels are stored in the buffer before merging.

Merging the consonants and the vowels (S _5-1-2 ) merges the final consonants and the vowels of the vowels, which can be combined into letters among the final consonants and the vowels stored in the buffer.

Saving the alphabet (S _5-2-1 ) stores the alphabet entered by the user in the buffer before merging the alphabet. Of course, English has no problem in implementing the letters even if the alphabetical order is input, the step of storing the alphabet may be omitted.

Merging the alphabet (S _5-2-2 ) merges the alphabet entered by the user or stored in the buffer. This finally completes the word the user wants and a sentence listing the words.

As described above, the character input method according to the present invention can correct the user's input even if there is an error, thereby accurately inputting the character that the user wants to input. In addition, the character input method according to the present invention supports a touch input operation and an eight-direction input operation on one key, so that up to 18 characters including multi-touch may be input on one key. In addition, the character input method according to the present invention supports the input operation of up to 8 directions including the touch input operation and the multi-touch in the 'SPACE' key, so that the 'SPACE' key is 'backspace' and 'space' according to the input operation. The operation of the 'key and the' enter 'key can be performed.
