Description

How to correct typo characters

The present invention relates to a method for correcting a typo character, the method for correcting a typo character that corrects a typo character input to a terminal into a correct character.

If you make a typo while typing characters (including English, Korean, numbers, special characters, etc.) on your PC or mobile device, the usual way to correct typos is to delete the backspace. Use the function keys to erase all characters entered after the typo, then type the correct character again, or move the cursor to the typo using the mouse (for PC) or finger touch (for mobile devices) I corrected a typo by deleting the characters and retyping the correct characters.

However, a method of correcting a typo using a delete function key such as a backspace has a problem in that not only a typo character but also all characters normally input between the typo character and the current cursor position are erased. In addition, the method of correcting a typo by moving the cursor to a typo character using the mouse is to release the mouse from the keyboard, move the cursor to the desired position, and move the cursor back to the current position after correcting the typo. There is a problem that the operation is cumbersome and time consuming. The same is true when the cursor is moved using a finger touch. In the case of a device having a small touch screen such as a mobile device, it is more difficult and cumbersome to move the cursor to the correct position because a finger touch must move the cursor to a desired position within the small screen.

In order to solve this problem, a so-called automatic correction function called an error correction method has appeared. This function is already commercially available and installed in various mobile devices. When the user enters the word A and the word A is determined to be a typo, the function automatically corrects the word B. The word B, which is automatically corrected, is already entered in the library and is not directly entered by the user.

As described above, the conventional automatic correction function sets the word that the system assumes to be entered by the user as a corrected input word instead of the word that the user inputs with the intention of correcting it. The wrong word is entered that is not. This is due in part to the limitations of words registered in the library. Because users frequently use new words or abbreviations on PCs or mobile devices, the problem caused by the limitations of these libraries becomes more serious when the library is not updated frequently. For this reason, many users are using the word correction function even though the device is equipped with the automatic word correction function.

Technical problem of the present invention relates to a typo character correction method that can easily correct the typo characters input to the terminal to the correct character. In particular, there is provided a correction method to facilitate the correction of typos in English characters.

According to an embodiment of the present invention, in a method for correcting a typo character in a terminal for correcting a character input with a typo, a typo character string of two or more characters is replaced with a correction character string of two or more characters while the terminal receives an input string through an input field. A modification request event determining process of determining whether a modification request event received from an inputter to be corrected occurs; A typo string extraction step of extracting a typo string to be replaced as the correction string by using two or more correction strings when a modification request event occurs; And a string replacement process of replacing and correcting the extracted typo string with the correction string.

The determining of whether the modification request event occurs comprises: a modification request first event determining process of determining whether a string of two or more characters is received after receiving a space character as the last character of the input string; A modification request second event determining step of determining which one of the input strings is touched; And when the modification request first event and the modification request second event are sequentially generated, determine that a modification request event has occurred, determine the last character string input after receiving the blank space character as a modification string, and touch the character string. And determining the replacement target area.

The determining of the touched character string as the replacement target area may include determining an area of the character string in the area where the input finger is touched as the replacement target area.

The replacement target area may be enlarged or reduced by a dragging selection of an inputter.

The typo string extraction process may include: extracting the same character that is identically included in both the corrected string and the replacement target area; And extracting a number of character strings corresponding to the corrected character string from the replacement target area as a typo character string based on the same character.

When there are two or more typo strings in the replacement target area, the typo string extraction process may be characterized by extracting a typo string to be replaced with the corrected string according to the number of touches of the inputter.

Determining whether the touch of the string has been continuously touched for a preset threshold time in the determination request second event determination process before the typo character string determination process occurs after the modification request event is generated. have.

The typo character string extraction process may include: extracting the same character that is identically included in both the corrected character string and the replacement target area if the touch character is continuously touched during the threshold time; And extracting a character that matches the same character from the replacement target area to a typo string.

The replacement target area is changed by dragging the area of the string in the area where the inputter's finger is touched, the typo string is extracted within the replacement target area selected by the dragging user, and popped up near the top of the input field. The modified text may be enlarged and displayed in the displayed popup field.

The area of the text in the area where the input finger is touched is enlarged and displayed in the pop-up field displayed in the pop-up form adjacent to the top of the input field, and the user moves the selection position in the pop-up field when the finger moves left and right after selecting the pop-up field. Character position selection can be made.

The method for correcting a typo character may include deleting a last character entered in an input field when dragging to the left on a touch screen keyboard for inputting a character, and inserting a space character in the input field when dragging to the right on a touch screen keyboard for receiving a character. It may be characterized by the input box.

According to the embodiment of the present invention, a typo character can be corrected by a simple operation, and user convenience can be increased.

However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various forms, and is provided to fully inform the scope of the invention to those skilled in the art. The invention is defined only by the scope of the claims. In addition, in the following description of the present invention, if it is determined that related related technologies and the like may obscure the gist of the present invention, detailed description thereof will be omitted.

1 is a diagram illustrating a terminal to which a character string is input according to an embodiment of the present invention, and FIG. 2 is a block diagram of a terminal according to an embodiment of the present invention.

The terminal 100 is a device that can receive text, and may correspond to a smartphone. In the following drawings, a smart phone as an example of the terminal 100 is described as an example, but not only a smart phone but also a desktop PC, a tablet PC, a slate PC, a notebook computer (notebook computer), digital broadcasting terminal 100, PDA (Personal Digital Assistants), PMP (Portable Multimedia Player), Navigation (Navigation), Digital Camera (MP3P), MP3P (MPEG layer 3 Player) have. Of course, the terminal 100 to which the present invention is applicable is not limited to the above-described type, and it is natural that the terminal 100 may include all the terminals 100 capable of communicating with an external device.

As illustrated in FIG. 2, the terminal 100 may include an input unit 110, a display unit 120, a memory 130, and a character correction unit 140.

The display unit 120 is a display window displayed on the terminal 100, and a keyboard for text input may be displayed.

The input unit 110 receives text from an input user who is a terminal user through the input field 10. Character input may be input by touching a character button displayed on the keyboard. The display unit 120 and the input unit 110 may be implemented as a single type of touch screen panel. The touch screen panel is a display window provided on the front of the terminal 100 to display a work screen by providing a touch screen screen capable of simultaneously inputting and displaying a graphic user interface (GUI) for input. Display.

In the following description and drawings will be described with an example of the English alphabet, it will be apparent that the present invention can be applied to other character systems in addition to the English alphabet.

The memory 130 is a storage unit that stores characters input through the input unit 110 (hereinafter, referred to as an “input string”). Storage unit SSD drive (Solid State Drive), flash memory 130 (Flash Memory), CF card (Compact Flash Card), SD card (Secure Digital Card), SM card (Smart Media Card), MMC card (Multi-Media A module capable of inputting / outputting information such as a card or a memory stick 130 may be provided inside the device or may be provided in a separate device.

The character correction unit 140 performs a function of replacing a typo character input as a typo among other input strings input through the input field 10 with another corrected character to correct it. To this end, the character correction unit 140 may include a two or more typo character string containing a typo character as a two or more character correction string including a correction character while the terminal 100 receives an input string through the input field 10. In addition, it has a modification request event determination process for determining whether a modification request event that is requested from the input to modify to replace. When a modification request event is generated, there is a typo string extraction process for extracting a typo string to be replaced as a modification string, and a string replacement process for replacing the extracted typo string with the modification string and correcting it. Detailed description thereof will be described later with reference to the flowcharts of FIGS. 3 and 4.

3 and 4 are flowcharts illustrating a typo character correction process according to an exemplary embodiment of the present invention.

The terminal 100 has the following processes in correcting a character input with a typo.

While the terminal 100 receives the input string through the input field 10, the terminal 100 receives a request from the inputter to replace the two or more typos including the typo characters with two or more modifications including the correction characters. A modification request event determination process (S311, S312, S313) for determining whether a modification request event occurs.

The determination of whether or not such a modification request event occurs first includes a modification request first event determination process (S311) of determining whether a string of two or more characters is input after receiving a blank space character as the last character of the input string. . For example, as shown in FIG. 5, when the last character of the input string input to the input field 10 is a blank space character, when a blank space character is input, the input cursor is positioned with one space. In this way, it is determined whether two or more character strings are input in a space of one space. Such a character string is a character string including two or more characters including a character to be modified by the inputter, and will be referred to as a character string hereinafter.

When the modification request first event occurs, a modification request second event determination process (S312) is performed to determine which one of the input strings is touched before the modification string is input. For example, as illustrated in FIG. 6, when an inputter touches a string to be modified, it may be determined that a modification request second event has occurred.

When a touch by the inputter's hand is made, a replacement target area is determined, and the replacement target area may be determined to a preset range. For example, in the case of modifying 'anoth' in FIG. 6, when the 'no' part is touched by hand, the selected 'no' and 'ath' areas are designated as correction character areas. If 'o' is selected, 'an' and 'th' adjacent to 'o' are also included as replacement areas. This is to make it easy to correct the text, and the constant letter or the predetermined distance before and after the selection position may be used as the replacement target area. This may vary depending on the font size.

On the other hand, when such a modification request first event and a modification request second event occurs in sequence, it is determined that a modification request event has occurred, and after receiving a blank space character, the last input string is determined as a modification string (S313). For example, in the example shown in FIG. 6, the last string 'ny' after the blank space is determined as the modified string.

Also, the touched string among the input strings is determined as a replacement target region. That is, the region of the character string in the region where the input finger is touched is determined as the replacement target region (S313). For example, in the example illustrated in FIG. 6, when the character string of the area touched by the input finger is a 'no' area, 'anoth' extended to a certain area range may be a replacement target area.

This replacement target area may be expanded or reduced by dragging selection of the inputter. For example, after 'anoth' is touched, it may be reduced to a string of 'no' by the dragging reduction of the inputter as shown in FIG.

Meanwhile, after the modification string and the replacement target region are determined due to the occurrence of the modification request event as described above, determining whether the touch of the string is continuously touched for less than a preset threshold time in the determination of the modification request second event ( S320). When the threshold time is set to 0.5 seconds, when the touch of the string is not touched continuously for more than 0.5 seconds, which is a preset threshold time, but as a short touch of 0.01 seconds, which is less than the threshold time (S320a), the typo string to be replaced as a correction string is two characters. There is a typo string extraction process (S331, S332) that is extracted using the modified string. That is, the present invention may extract a typo string associated with the modified string using two or more characters.

The typo string extraction includes extracting the same character that is identically included in both the modified string and the replacement target area (S331), and replacing the string having the number of characters and the character position corresponding to the modified string based on the same character. It extracts from the region and extracts the typo string (S332).

In addition, a string replacement process (S340) is performed in which the extracted typo string is replaced with a modified string to be modified.

For example, when 'ny' is input as the modification string as shown in FIG. 6, the character 'n', which is identically included between the replacement target region 'anoth' and the modification string 'ny', is the same character. Based on the same character 'n', 'no', which is a character string having the number and character position corresponding to the modified string, is extracted from the replacement target area and determined as a typo string. And, by replacing the extracted typo string 'no' with the modification string 'ny', the word 'anothing' may be modified to 'anything'.

Similarly, when 'yt' is input as the correction string as shown in FIG. 8, 't', which is the same character between the replacement target region 'anoth' and the correction string 'yt', is extracted as the same character. Based on the same character 't', the string 'ot', which has the number of characters corresponding to the modified string and the character position, is extracted from the replacement target area and determined as a typo string. In addition, by replacing the extracted typo string 'ot' with the modification string 'yt', the word 'anothing' may be modified to 'anything'.

Similarly, when 'nyt' is input as the modification string as shown in FIG. 9, the characters 'n' and 't', which are identically included between 'anoth' which is the replacement target region and 'nyt', which are the modification target strings, are respectively provided. Extracted as the same character, 'not', which is a string having the number of characters and character positions corresponding to the modified string, based on the same characters 'n' and 't', is extracted from the replacement target area and determined as a typo string. In addition, the existing word 'anothing' may be modified to 'anything' by replacing the extracted typo string 'not' with the modification string 'nyt'.

Similarly, when 'yth' is input as the modification string as shown in FIG. 10, the characters 't' and 'h', which are identically included between the replacement target region 'anoth' and the modification string 'yth', are respectively Extracted as the same character, 'oth', which is a character string having the number and character position corresponding to the modified string based on the same character 't' and 'h', is extracted from the replacement target area and determined as a typo string. And, by replacing the extracted typo string 'oth' with the modification string 'yth', the word 'anothing' may be modified to 'anything'.

As above, all characters are recognized as individual. Each character of 'anything' is compared with two or more letters to be modified to undergo a modification process. As the number of comparison letters to be corrected increases, the accuracy of correction may increase. After the correction, the cursor is at the end of the sentence.

On the other hand, when there are two or more typo strings in the replacement target region, the typo string extraction process may extract a typo string to be replaced with the corrected string according to the number of touches of the inputter. In the case of the same English in the selection area, the part that stores the first corrected position so that the same English located after the first corrected position is touched in succession.

For example, if you attempt to enter 'error' but a typo string of 'eoror' occurs, there is more than one typo in the replacement target area. In this case, if you touch 'eoror' once after entering 'rr' as the correction string, it is modified to 'error'. On the other hand, if you touch 'eoror' twice in a row after entering 'rr' as a modification string, it is modified to 'eorrr'.

On the other hand, after the correction request event is generated, but before the typo string identification process, it has a step (S320) of determining whether the touch of the string was touched less than a predetermined threshold time in the process of determining the correction request second event, In case of continuous touch over the threshold time, the substitution is performed in the form of character insertion. For example, when the threshold time is 0.5 seconds, after 'ny' is input as the correction string as shown in FIG. 11, and when 'anth' is touched by being pressed for 0.5 seconds or longer in the input string, the threshold time is continuously maintained. It can be determined that the touch has been received.

As such, when the touch of the string is continuously touched for more than a predetermined threshold time (S320b), the process of extracting the same character included in both the modified string and the replacement target area (S333), and the character matching the same character Extracts from the replacement target region to a typo string (S334). In operation S340, the extracted typo string is replaced with a modified string to be modified.

For example, when 'ny' is input as the modification string as shown in FIG. 11, the character 'n', which is identically included between 'anth' as a replacement target region and 'ny' as the modification string, is the same character. The extracted character 'n' that matches the same character 'n' is extracted from the replacement target area and is determined as a typo string. The existing word 'anthing' may be modified to 'anything' by inserting 'y' into the extracted typo string 'n' and replacing it with 'ny', which is a modification string completed.

Similarly, when 'yt' is input as the modification string as shown in FIG. 12, 't', which is the same character between 'anth' as the replacement target region and 'yt' as the modification string, is extracted as the same character. , And extracts 't', which is the same character as 't', from the replacement target area and determines it as a typo string. In addition, by replacing the extracted typo string 't' with the modification string 'yt', the word 'anthing' may be modified to 'anything'.

Similarly, when 'nyt' is input as the correction string as shown in FIG. 13, the characters 'n' and 't', which are identically included between 'anth' as the replacement target region and 'nyt' as the modification string, are respectively Extracted as the same character, 'nt', which is a string matching the same characters 'n' and 't', is extracted from the replacement target area and determined as a typo string. In addition, by replacing the extracted typo string 'nt' with the modification string 'nyt', the word 'anthing' may be modified to 'anything'.

Similarly, when 'yth' is input as the correction string as shown in FIG. 14, the characters 't' and 'h', which are identically included between 'anth' as the replacement target region and 'yth' as the modification string, are respectively Extracted as the same character, 'th', which is a string matching the same characters 't' and 'h', is extracted from the replacement target area and determined as a typo string. In addition, by replacing the extracted typo string 'th' with the modification string 'yth', the word 'anthing' may be modified to 'anything'.

On the other hand, in order to correct the correction when the alphabets of the alphabet letters overlap, the area to be replaced is changed by dragging the area of the string in the area where the inputter's finger is touched, and a typo in the replacement area selected by the inputting device's dragging. The character string may be extracted, and the modified character string may be enlarged and displayed in the pop-up field displayed in the pop-up form adjacent to the top of the input field 10.

Therefore, when the touch is long, the inserted character in the touch selection area is displayed on the top of the keyboard to accurately select the character position to be inserted. For example, as shown in FIG. 15, the character completed to be inserted into the touch selection area during the long touch is displayed on the upper end of the keyboard to accurately select the character position to be inserted. If the hit is 'apple' but the typo 'appe' is entered, touch the appe part after entering the last one space and enter pl. It is a method of modifying the expressed character at the moment of expressing touch with apple. The modified character image is displayed on the top of the keyboard as shown above so that the characters can be inserted at the correct position even when the alphabet overlaps.

In addition, as shown in FIG. 16, the position at the time of the display window character selection is shown in FIG.

As shown in the figure, the current selection position is enlarged and displayed on the screen above the display window, and when the user moves left and right after selection, the display screen selection position is also moved according to the user's character position selection. That is, the area of the string in the area where the input finger is touched is enlarged and displayed in the pop-up field displayed in the form of a popup adjacent to the top of the input field. The user character position selection can be made.

On the other hand, in the typo character correction method, as shown in FIG. 17, when the character is dragged to the left on the touch screen keyboard to receive the character, the last character entered in the input field 10 may be deleted.

In addition, in the method of correcting a typo character, a blank space character may be input in the input field 10 when the character is dragged to the right on the touch screen keyboard to which the character is input. Therefore, you can space the letters by touching the text box on the board and dragging it to the right.

The embodiments in the above description of the present invention are presented by selecting the most preferred examples to help those skilled in the art from the various possible examples, and the technical spirit of the present invention is not necessarily limited or limited only by the embodiments. However, various changes, modifications, and other equivalent embodiments may be made without departing from the technical spirit of the present invention.
