KR20220039661A - The simple method of correction of the typograghical error while text input at electronic device - Google Patents

Abstract

In a method of correcting an input character (immediately due to a typo) in a device for inputting the characters through a keyboard, substantially, by generating a single signal (without a step of substantially deleting) the input character (immediately by the user) is replaced with the character inputted immediately before) with a character having a specific relation to the character. A first button, which is a button which was touched just before, is displayed to be distinguished from one or two or more other buttons until a second button, which is another new button, is touched, after the second button, which is a new button, is touched, a button display method in an electronic device, characterized in that the display is displayed indistinguishably from one or two or more other buttons except for the second button.

Description

A simple way to correct typos when entering text on an electronic device, etc.

A simple method for correcting typos when inputting text in an electronic device and a method for displaying manipulated buttons.

Conventionally, when a character that was not originally targeted is input due to a typo, the character is deleted, and then the originally targeted character is input. Therefore, in the case of the QWERTY keyboard, in most cases, two strokes (one stroke of the delete button, one stroke of the originally targeted character button) are required to input a character input due to a typo as a new character that was originally targeted.

Now, let's look at the conventional general character input situation.

It is safe to say that Hangul has the fastest character input speed on small keyboards including 3X4 keyboards.

There are various methods for inputting Hangul using a 3X4 keyboard, including the Cheonjiin method, the Naratgul method, and the Sky method.

Of course, you can enter Korean more quickly if you enter it through the QWERTY keyboard.

However, when trying to input characters from various countries, including English and Korean, through the QWERTY keyboard provided in the smartphone, especially on the touch screen, errors occur frequently, and accordingly, the characters input due to the typos are deleted, In a situation where the inconvenience of having to re-enter the originally targeted character frequently occurs,

Since Hangul input can be entered fairly quickly even through the 3X4 keyboard, the main reason is to avoid typos, instead of using the QWERTY keyboard, which can input faster , various Korean input using the 3X4 keyboard mentioned above While the number of Koreans who input text through this method is about 70% even in the smartphone era,

Even in the case of English, where the number of grapheme is only 26 (for reference, the Korean alphabet is 40), it was very difficult to input characters with the 3 X4 keyboard even from the old feature phone era, so almost the absolute majority of foreigners When inputting your own language (the typo that occurs frequently when using the QWERTY keyboard like Koreans, with the 3X4 keyboard, it is practically impossible to avoid), you can just enter it through the QWERTY keyboard, being careful not to make a typo. there is only

In this situation, if typos can be easily corrected, the proportion of Koreans using the QWERTY keyboard will rise sharply, and the convenience of using the QWERTY keyboard for foreigners will be greatly improved.

In addition, through the technology of the present application, which will be introduced more in the future, it is possible to easily correct typos on a small keyboard in which a large number of characters are assigned to one button including a 3X4 keyboard, so the usability of the 3X4 keyboard will be greatly improved.

Let's take a closer look at the prior art.

Typing text on small mobile devices, including cell phones, often causes typos.

For example, in most cases of the conventional feature phone, a small physical button including a 3X4 keyboard rather than a QWERTY keyboard is provided. Most of the time, the target text button was touched, but a lot of typos occurred due to follow-up operation mistakes (the reason will be explained in a little more detail later),

Of course, even when using a smartphone, even when entering characters through a small keyboard including a 3X4 keyboard on the touch screen, many characters are assigned to one button in most cases, so a lot of typos are occurring,

When a character is input through a feature phone having a conventional touch-type keyboard or a QWERTY keyboard on most smart phone touch screens, the size of the character button is small, and thus more errors occur.

As a conventional method for preventing a conventional typo,

This is a method applied to Samsung Electronics' Galaxy S in Korea, and also to introduce a method to prevent typos applied to smartphones of almost all smartphone companies around the world, including Apple and LG Electronics,

For example, as shown in Fig. 2, if a finger is touched on the 'D' character button, the 'D' character button is displayed on the 'D' character button while the 'D' character button is displayed in a different color from other buttons. There is a method in which a pop-up with a 'D' displayed several times larger ('POP UP' in Fig. 2, also referred to as a preview function) is created, and the 'D' is inputted after removing the finger from the 'D' letter button. .

(And, as soon as you take your finger off the 'D' letter button, as shown in Fig. 1, the 'D' letter button is displayed in the same color as the other buttons, and the pop-up above the 'D' letter button disappears.).

However, even if the above method is used to reduce typos, typos still occur frequently.

Because, although it is said that typos occur frequently, in most cases, the target character is entered correctly, that is, it does not occur very often, so the user also correctly touches the target character button this time. This is because, thinking that he did, he immediately removed his finger without checking the characters displayed in the pop-up properly.

If you want to properly input characters in the conventional method mentioned above,

Through the pop-up, check which text button you touched,

If the target character button is properly touched, release your finger immediately to enter the target character,

If it is determined that the wrong character button is touched instead of the target character button, the target character must be input by dragging the finger to the target character button without lifting the finger.

However, input like this requires a lot of attention to check the characters displayed in the pop-up every time the user enters each character, so the user becomes quite tired and the character input speed is significantly reduced. Since there is not a huge amount of typos that can be tolerated, even when the wrong button is touched, the user thinks that the target text button has been accurately touched even this time, and without checking the text in the pop-up properly, Since the characters are separated and entered, errors often occur.

After all, even with a tool called pop-up, errors are bound to occur frequently.

That is, provided in small electronic devices including smartphones touch type In the QWERTY keyboard For a number of reasons, including those described above, ( tablet pc QWERTY keyboard or desktop pc QWERTY keyboard It becomes very difficult to avoid typos (which occur more often). In this way, in a situation in which it is difficult to avoid typos anyway, if a method to easily correct typos is developed, the effect on the convenience will be very high. big number there is only

In addition, there are countless ways to input characters with a keyboard consisting of buttons assigned a plurality of characters per one character button, including a 3X4 keyboard, rather than a button with one character assigned to each character button including the QWERTY keyboard. Developed and the size of the character button on the keyboard to which such a method is applied is larger than the button on the QWERTY keyboard, but a number of characters are assigned per one character button, subsequent problems, and inherent disadvantages of the developed methods For various reasons including the above, a lot of typos occur, and after deleting the characters input due to the typos, the original target characters are input. Anyway, you need at least 2 strokes to correct the typo.

In the present application, even when a character is input through the buttons to which a plurality of characters are assigned to one such character button, the step of the user deleting the inputted character due to a typo is eliminated, and a signal is generated, so that the , a character input due to a typo is directly replaced with a new character originally targeted, so that the original target character can be input. Thus, in most cases, only one stroke is required.

The matters described as the background art are only for enhancing the understanding of the background of the present invention, and all of the matters described as the background art correspond to the prior art already known to those of ordinary skill in the art It should not be taken as an acknowledgment.

In this application, the step of the user deleting the input character due to a typo is eliminated, and by generating a certain signal (eg, a left arrow (or right arrow) for implementing the method of the present invention in FIG. 3 (or FIG. 4 ) is displayed) By pressing the control button ('LEFT BUTTON' or 'RIGHT BUTTON' in FIGS. 3 and 4), or by pressing the control button for character correction in which characters for implementing the present method in FIG. 23 (or FIG. 24 or 40) are displayed (FIG. 23) , by pressing 'LEFT BUTTON' or 'RIGHT BUTTON') in FIGS. 24 and 40), the character input due to a typo, , to the left (or right) character button of the character button to which the character input due to the typo is assigned The assigned character, that is, the character originally targeted can be entered by replacing it with the character assigned to the originally targeted button . Therefore, in the case of the QWERTY keyboard to which the method of the present application is applied, in most cases, only one stroke is required to input a character input due to a typo as a new character that was originally targeted.

In the above, the control button marked with 'left arrow' is 'LEFT BUTTON' of FIG. 3 or 4, and the control button marked with 'right arrow' may be about 'RIGHT BUTTON' of FIG. 3 or 4, and the character Control buttons marked with can be 'LEFT BUTTON' or 'RIGHT BUTTON' of FIG. 23 (or FIG. 24 or 40).

That is, in the case of the QWERTY keyboard, a character input due to a typo is replaced with a new character that was originally targeted. In the conventional method, two strokes are required, but only one stroke is required by the method of the present application.

We cannot all agree that the effect is great on a desktop keyboard where typos do not occur frequently, but it can be said that the effect is very large on small mobile devices, including smartphones, where typos frequently occur.

In order to quickly understand the present application, the technology of the present application is applied to a device equipped with a touch-type virtual QWERTY keyboard on a small display screen such as a smartphone among various situations in which the technology of the present application can be applied and various embodiments in each situation However, a very useful embodiment will be described first.

24 is a diagram illustrating an embodiment of a smart phone equipped with a virtual keyboard on a touch screen to which the technology of the present application is applied. Compared to the conventional general smart phone virtual keyboard as shown in FIG. 1, at the bottom of FIG. 24, a character button (eg, 'S') located immediately to the left of the button to which the immediately inputted character (eg, 'D') is assigned. A control button ('LEFT BUTTON' or 'RIGHT BUTTON' in Fig. 24) that displays the letters ('S' and 'F') assigned to the letter button (letter button) and the letter button located immediately to the right (eg 'F' letter button) ' = 'S' or 'F' control button on a gray background).

[In fact, if the technology of the present application is applied to a smartphone, in a conventional smartphone drawing such as FIG.

As shown in Fig. 23, the shift button and the delete button are moved to the bottom, and as a control button for applying the technology of the present application, a letter button (white background 'S' letter button) and a control button ('LEFT BUTTON' or 'RIGHT BUTTON' in Fig. 23) that displays the character ('S' or 'F') assigned to the character button (white background 'F' character button) located immediately to the right = 'S' or 'F' control button on a gray background) is positioned in place of the conventional shift button and delete button, or

As shown in Fig. 40, the positions of the shift button and the delete button are the same as in the prior art, but as a control button for applying the technology of the present invention, a letter button (white background 'S' letter button) and a control button ('LEFT BUTTON' or 'RIGHT BUTTON' in Fig. 40 = 'S' on a gray background, or 'F' control button ) is placed next to the conventional space button

It is judged to be better, but in order to improve unity and understanding with those that will be described later various embodiments, the description will be made based on FIG. 24.]

First, it is recommended that the starting point of application of the present technology be implemented slightly differently from the conventional technology, as follows, in order to apply the technology of the present application as comfortably as possible to the user.

The conventional technology applied to Samsung Electronics' Galaxy S described in the 'Technology Background to the Invention' section is briefly described once again.

When a certain letter button (eg, 'D' letter button) is being touched, as shown in FIG. 2, as the color of the letter button changes differently from other buttons, a large pop-up is formed directly above the button,

When a touch on a certain text button is released, the pop-up disappears, and the color of the text button touched just before is returned to the same color as other buttons.

However, when the technology of the present application is applied, if the display for the touched button starts to be implemented slightly differently from the conventional one as follows, when the technology of the present application is further advanced later, the user can clearly determine what character button the button touched just before It will be possible to make a decision, and it will be more convenient for the user. (However, even if it starts to be implemented in the same way as in the prior art, there is no problem in implementing the technology of the present application.)

In a little more detail, when applying the technology of the present application,

When a certain text button is being touched, the color of the text button changes color differently from other buttons, and a large pop-up is formed just above the button,

When the touch of a certain text button is released, it is the same as the prior art until the pop-up disappears. The color of the text button that was touched just before is maintained as it is, in a different color from other buttons, and when a new button is touched, another button It is recommended to have the same color as the field. .

(In fact, it would have been better if it had already been implemented in the method recommended above in the prior art. Because, in the prior art, the pop-up formed in the immediate vicinity of the touched character button disappears as soon as the touch of the finger is released from the character button, And, in actual use, since the touch time is very short, it is also difficult to accurately recognize the text displayed in the pop-up.)

The following process is also performed on the assumption that the above-described method for displaying the state of the touched button (eg, color processing) is applied to the present technology.

24, in the process for inputting 'SO GOOD' into the character input window in 'AREA-D' of FIG. 24,

I tried to input 'D', the last character, in a situation where 'SO GOO' was properly entered (not shown), but after the wrong 'S' character button was touched, the touch of the finger was released. Assume that 'S' is inputted into the character input window at -D', and the cursor is positioned immediately after 'S' entered as a typo like 'AREA-D' in FIG. 25 .

And, suppose that the color of the 'S' letter button is displayed differently from other buttons as shown in FIG. 25. (After all, 'SO GOOS' has been input.)

In this situation,

In the past, ' that was entered due to a typo S' is deleted by the user pressing the delete button, and the ' that was originally intended to be entered D' entered, but

In this application, the ' entered due to a typo S' without the user deleting ' S' cast ' D' can be changed to

For example, to explain with reference to Figs. 25 and 26, at the bottom of the display screen of Fig. 25,

The button to which the character ('S') entered immediately before is assigned (that is, the 'S' character button)

'A' assigned to the character button ('A' character button) on the left is assigned to the control button 'LEFT BUTTON' in FIG.

'D' assigned to the letter button ('D' letter button) on the right side is assigned to the control button 'RIGHT BUTTON' in FIG.

Among the control buttons marked with 'A' and 'D', by touching the control button marked with 'D' ('RIGHT BUTTON' in FIG. 25), ' S' can be replaced with 'D' as shown in Figure 26. (In the end, 'SO GOOD' was entered.)

That is, it is not a concept in which the user inputs 'D' after deleting 'S' as in the prior art.

(And, in the description of the embodiment of the present application, the touched button may maintain a different color from other buttons even after the touch is released. It is also possible to implement the technology of the present invention by reverting like this, so, in general, the conventional desktop cannot change the color of the button. The typo correction method of this company will not have much effect, but it can be applied to the PC's physical keyboard.)

Let's review the above examples once again, and find out the meaning of the implied phrases claimed in the present application.

24, in the process for inputting 'SO GOOD' into the character input window in 'AREA-D' of FIG. 24,

Until 'SO GOO' was entered correctly (not shown), an attempt was made to input the last character 'D', but after the wrong 'S' character button was touched, the finger's touch was released. 'S' was entered due to a typo in the character input window in -D' (after all, 'SO GOOS' was inputted), and as shown in Figure 25, the 'S' entered as a typo like 'AREA-D' Let's say the cursor is positioned behind it.

When the above state is reached, the first step proceeds.

" Step 1: A step in which the character at the position derived by the position regulation (1) in a specific relationship with the cursor position or state in the character input window is grasped ".

(in the first step,

It is recommended that the position derived by the position regulation (1) in a specific relationship with the cursor position or state in the character input window is the position immediately before the cursor.)

In the first step phrase, 'a position derived by the position definition (1) of a specific relationship with the cursor position and state' is the position immediately before the cursor in this embodiment.

(However, it is up to the rule (1) to determine in advance how far the position is before and after the cursor, including not only immediately before the current cursor position, but also immediately before, immediately before, and immediately after the current cursor position, as in this embodiment. )

In that case, after all, 'a character at a position derived by the position regulation (1) in a specific relationship with the cursor position and state' means a character to be changed in the future, and the character immediately before the cursor input due to a typo in this embodiment In, it is ' S' .

(After all, in this embodiment, the 'character identified in the first step' is ' S' . )

Also, depending on the cursor state, the 'position derived by the cursor position and state and the specific positional relationship rule (1)' may change.

In general, since the cursor state in portable electronic products including smartphones is in the INSERT mode on the desktop PC, in this embodiment it was the position just before the cursor, but if in the NOT INSERT mode on the desktop PC, the current cursor position itself is It would be most desirable to use the 'position derived by the cursor position and state and a specific relation rule (1)'.

(However, even in the NOT INSERT mode, the rule (1) is up to pre-determining, including how far the distance from the cursor is to the front and rear, including just before, immediately before, and immediately after the cursor. .)

And, suppose that the color of the 'S' letter button is displayed differently from other buttons as shown in FIG. 25 .

In this situation,

Conventionally, the user pressed the delete button to delete the input 'S' due to a typo, and input the 'D', which was originally intended to be input, but

In the present application, the user may change the 'S' to 'D' without deleting the 'S' input due to a typo. I will explain this in detail.

Step 2: One or more characters assigned to the character button at one or more positions derived by the position regulation (2) of a specific relationship with the position of the character button on the keyboard to which the character identified in the first step is assigned is identified step to be

(in the second step,

The character button of one or more positions derived by the position regulation (2) of a specific relationship with the position of the character button on the keyboard to which the character identified in the first step is assigned is the character button assigned to the character identified in the first step It is recommended that the character button is located immediately to the left or right of the character button on the keyboard.

In the perspective of the embodiment referring to FIG. 30,

In the second step,

The character button derived from one or more positions derived by the position regulation (2) of a specific relationship with the position of the character button on the keyboard to which the character identified in the first step is assigned is the character button to which the character identified in the first step is assigned It is recommended that the character button is located directly above or below the character button on the keyboard. )

To explain the above two-step phrase, for example, with Figs. 25 and 26,

It has already been mentioned in the description of the first step phrase that the 'character identified in the first step' is 'S',

The 'character button on the keyboard to which the character identified in the first step is assigned'

Of course, it will be the 'S' letter button on the keyboard in 'AREA-E' of Fig. 25,

'The character button at one or more positions derived by the position regulation (2) of a specific relationship with the position of the character button on the keyboard to which the character identified in the first step is assigned' is

In this embodiment, the letter button 'A' and the letter button 'D', which are the letter buttons immediately to the left or right of the letter button ('S' letter button) on the keyboard to which the letter identified in the first step is assigned. .

(However, 'character buttons at one or more positions derived by the position regulation (2) of a specific relationship with the position of the character button on the keyboard to which the character identified in the first step is assigned' is

As in this embodiment, not only the letter button immediately left or right of the letter button ('S' letter button) on the keyboard to which the letter identified in step 1 is assigned, but also the letter button immediately left or right, immediately left or right In the first step, including any one or more of immediately right, immediately left, immediately right, immediately above, immediately below, immediately above, below, immediately, right, or immediately below of The regulation (2) regarding the position of the character button in which direction and how far away from the character button on the keyboard to which the identified character is assigned is up to pre-determining.)

In the end, 'one or more characters assigned to the character button at one or more positions derived by the position regulation (2) in a specific relationship with the position of the character button on the keyboard to which the character identified in the first step is assigned ' is a character that will be a candidate character(s) to be changed to such a character in the future, and in this embodiment, the character ('S') input immediately before (cursor) is assigned To one or more letter buttons ('A' letter button or 'D' letter button) derived by the location rule (2) of a specific relationship with the location (eg, immediately left or right of the 'S' letter button) That's the way it's assigned the letter (' A' or ' D' ) .

And, of course, in this embodiment, the character identified in the second step is ' A' or ' D' .

' Third step: a step in which one or more characters (any one or more characters) identified in the second step are assigned to one or more control buttons '

(in the third step,

All of the one or more characters identified in the second step are applied to the one or more control buttons. allotted recommend that

In the third step,

If one or more characters (any one or more characters) identified in the second step are assigned to one or more control buttons, it is recommended to display them.

In the third step,

It is recommended that one or more characters (any one or more characters) identified in the second step are assigned 1:1 to one or more control buttons. That is, it is recommended that one character be assigned to each control button.)

In the third step, the word 'control button' appears for the first time, and the 'control button' can be said to be a button whose function is to change an already entered character to another character.

At the bottom of the display screen of FIG. 25, there are two control buttons 'LEFT BUTTON' and 'RIGHT BUTTON'. The character identified in step 2 is assigned to this control button(s).

That is, the characters assigned to the control button(s) are continuously changed as the cursor position and input are continued.

That is, in this embodiment, 'A' or 'D', which is the character identified in the second step, is assigned to the control button(s) of 'LEFT BUTTON' or 'RIGHT BUTTON' of FIG. 25 .

And, in this embodiment, 'A' or 'D' assigned to the control button of FIG. 25 is displayed.

(The letter button ('A' letter button) to the left of the button ('S' letter button) to which the letter ('S') entered immediately before is assigned and the letter button to the right ('D' letter button) ), 'A' or 'D' is assigned and displayed on the control button called 'LEFT BUTTON', and 'D' is assigned and displayed on the control button called 'RIGHT BUTTON'.)

For reference, the assigned character may or may not be displayed on the control button.

That the assigned character is displayed on the control button means that 'A' or 'D' is displayed on the control button of FIG. 25 as in this embodiment,

The fact that the assigned character is not displayed on the control button includes that only any pattern including an arrow indicating a direction may be displayed instead of the assigned character, and that the button display state may be blank.

In the second step, the 'specific relationship position regulation (2)' is expected to be relatively simple as in this embodiment in most cases where the technology of the present application is applied by someone in the future, so even if the display behavior of the control button is blank, it is It is expected that there will be no problems. Because, even if 'A' or 'D' is not displayed on the control button of FIG. 25,

If the regulations for steps 2 and 3 are

(Cursor) of the button ('S' letter button) to which the previously entered letter ('S') is assigned.

The character ('A') assigned to the character button ('A' character button) on the left is assigned to the control button called 'LEFT BUTTON',

If it is a rule that the character ('D') assigned to the character button ('D' character button) on the right is assigned to the control button called 'RIGHT BUTTON',

'A' is assigned to the control button called 'LEFT BUTTON',

This is because it is easy to know that 'D' will be assigned to the control button 'RIGHT BUTTON'. (An example of the behavior indicated by the arrow will be presented later.)

Step 4: Step in which any one of one or more control buttons is selected and the character assigned to the selected control button (or until displayed after assignment) is identified

To explain the above phrase through this embodiment, among the control button(s) called 'LEFT BUTTON' or 'RIGHT BUTTON' to which 'A' or 'D' is assigned, which is the control button to which the letter in step 3 is assigned. If the control button marked with 'D' ('RIGHT BUTTON' in FIG. 25) is touched and selected, the character assigned to the selected control button will be, of course, recognized as 'D'.

Step 5: A step in which the character identified in the first step is changed to the character identified in the fourth step.

To explain the above phrase through this embodiment, 'S', which is the letter identified in step 1, is changed to 'D', which is the letter identified in step 4.

To explain a little more, 'S' input due to a typo in AREA-D of FIG. 25 can be replaced with 'D' as shown in FIG. 26 . In the end, 'SO GOOS' was changed to 'SO GOOD'.

That is, it is not a concept in which the user inputs 'D' after deleting 'S' as in the prior art.

In the fifth step,

The process of changing the character identified in the first step to the character identified in the fourth step is

The character identified in the first step may be directly changed to the character identified in the fourth step, or the character identified in the fourth step may be input after the character identified in the first step is deleted.

To explain the above phrase through this example,

In the above, the method of the present application merely changes the character input due to a typo (eg, 'S') to the originally targeted character (eg 'D'), but it is said that it is the user's conception or visual easy,

In terms of electronic technology,

If you touch the control button ('RIGHT BUTTON' in FIG. 25) marked with 'D' at the bottom of the display screen of FIG. 25,

It can be implemented so that 'S' is directly replaced with 'D',

Or, 'S' is (automatically) deleted almost instantly and 'D' is entered, so that, in the eyes of the user, 'S' is immediately replaced with 'D' without the process of deleting 'S'. may be

Let's take another embodiment to better understand the technology of the present application, including making it clear that the character assigned to the control button can be changed.

In the process for inputting 'SO GOOD' into the character input window as shown in FIG. 24,

I tried to input 'D', the last character, in a situation where 'SO GOO' was properly entered (not shown), but after the wrong 'F' character button was touched, the finger's touch was released, so as in FIG. 27, 'AREA' Assume that 'F' is inputted into the character input window at -D', and the cursor is positioned immediately after 'F' entered as a typo like 'AREA-D' in FIG. 27 .

And, suppose that the color of the 'F' letter button is displayed differently from the other buttons as shown in FIG. 27. (After all, 'SO GOOF' is inputted.) (As mentioned earlier, FIG. 41 rather than FIG. 27 controls It seems to be a better layout for the button layout.)

In this situation, in the prior art, the user deleted the input 'F' due to a typo and input the 'D' that was originally intended to be input . You can change ' F' to ' D' .

For example, to explain with reference to FIGS. 26 and 27, the character button (that is, the 'F' character button) to which the character ('F') input immediately before is assigned at the bottom of the display screen of FIG. 'D' is displayed among the control buttons marked with 'D' and 'G' assigned to the letter button ('D' letter button) on the left and letter button on the right ('G' letter button) By touching the displayed control button ('LEFT BUTTON' in FIG. 27), 'F' entered as a typo in AREA-D in FIG. 27 can be replaced with 'D' as shown in FIG. 26. (After all, 'SO' It was entered as 'GOOD'.)

<Delete: Deletes duplicates except for alphabets>

That is, as before F' After deleting ' D' It is not a concept to input .

In the above, the method of the present application is a character input due to a typo (eg, ' F' ) was originally targeted (e.g. ' D' ), but it is said that it is a technology that replaces

In terms of electronic technology,

27 of FIG. of the display screen ' at the bottom D' Control buttons marked with 27 of FIG. ' LEFT BUTTON' ) is touched,

' F' go ' D' It can be implemented to be replaced directly with

Otherwise, ' F' is (automatically) deleted almost instantly, ' D' is entered, and in the eyes of the user, ' F ' is immediately replaced with ' D' without the process of deleting ' F' . may be

------------------------------------------------------------ ------------

Of course, the technology of the present disclosure may be applied while moving the position of the cursor.

For example, an already input character including a character input due to a typo may be replaced with a new character including the originally targeted character without a step of the user deleting the character input immediately before the moved cursor position.

<Delete: unnecessary>

(For reference, in the examples so far, when the cursor is displayed, an English capital letter ' L' lowercase letter of ' l' I didn't mark it because I thought it would be confusing.)

For example, when 'SO GOOD' is input, the cursor is moved by the user to be positioned between 'S' and 'O' of 'SO' as shown in 'AREA-D' in FIG. 43,

If the 'position derived by the position regulation (1) of a specific relationship with the position or state of the cursor in the text input window' in the first step is 'the position immediately before the cursor',

The characters identified in 'Step 1: Step in which the character at the position derived by the position regulation (1) in a specific relationship with the cursor position or state in the character input window is grasped'

becomes 'S',

'A' assigned to the letter button (='A button') located on the left side of the 'S letter button' and 'D' assigned to the letter button located on the right side of the 'S letter button' (='D button') ' is displayed on the control button. In that state, by touching the control button marked with 'A' ('LEFT BUTTON' in Fig. 43), 'S' can be replaced with 'A'. (After all, It is input as 'AO GOOD' (not shown).)

------------------------------------------------------------ -----------

<Delete: Plot is virtually duplicate>:

A brief summary of the above few paragraphs:

Replacing previously entered characters including characters entered due to typos with new characters including originally targeted characters without “substantially” deleting the characters previously entered by the user can say that

The word “substantially” above means

As explained in the previous few paragraphs

Characters entered due to a typo (eg ' F' ) was originally targeted (e.g. ' D' ), literally, can be directly replaced with,

Characters entered due to a typo (eg ' F' ), without the user giving a separate deletion command, the original target character (eg, ' D' ) by touching the assigned control button,

Characters entered due to a typo (eg ' F' ) is momentarily deleted, and then the originally targeted character (eg, ' D' ) is entered,

Characters entered due to a typo (eg ' F' ) was originally targeted (e.g. ' D' ), including meanings that can have the effect of replacing them.

As in the above embodiment, since the horizontal length of each character button is less than the vertical length in the virtual keyboard that appears when inputting characters by standing vertically on the conventional smart phone, it is a rectangular shape elongated in the vertical direction, so in most cases Occurrence of typos is often caused by erroneously touching a text button located immediately to the left or right of the originally targeted button.

Therefore, when the technology of the present application is applied to the virtual keyboard as shown in Fig. 1, which appears most frequently when inputting text with the smartphone standing vertically, the original target was to As a control button necessary to change to a new character including a character, as shown in FIG. 23 or FIG. 24, the character assigned to the character button located immediately to the left of the button to which the character input immediately before (cursor) is assigned and the character assigned to the character button positioned immediately to the right The control buttons displayed will suffice.

However, when the horizontal length of each letter button is greater than the vertical length as shown in FIG. 9 (correct), that is, since each letter button has a rectangular shape that is elongated from side to side, in most cases, the occurrence of a typo occurs right away from the originally targeted button. In many cases, it may be caused by mistakenly touching a character button located on the upper side or the lower side.

In the case of applying the technology of the present invention to a keyboard when the horizontal length of each character button including FIG. 9 (correct) is greater than the vertical length, the character originally targeted for the already input character including the character input due to a typo To explain the control button required to change to a new character including

As shown in Figure 30 (cursor) of the character button (eg, 'S' character button) to which the character input immediately before (eg 'S') is assigned

A letter button located directly upwards (eg 'L' letter button) and

On the letter button located directly below (eg 'Y' letter button)

A control button displaying the assigned letter ('L' and 'Y') will suffice.

(The control button to which 'L' assigned to the character button (eg, 'L' character button) located in the immediate upper direction is assigned is 'UP BUTTON' in FIG. 30,

The control button to which 'Y' assigned to the character button (eg, 'Y' character button) located in the lower direction is assigned is 'DOWN BUTTON' in FIG. 30).

If, in FIG. 27, the character button (eg, 'F' character button) to which the previously inputted character (eg 'F') is assigned

The letter button located immediately to the left (eg 'D' letter button) and

The letter button located immediately to the right (eg 'G' letter button) and

A letter button located directly upwards (eg 'R' letter button) and

On the letter button located directly below (eg, 'C' letter button)

If a control button for displaying assigned letters ('D', 'G', 'R', 'C') is required, a control button may be provided as shown in FIG. 31 .

The control button in FIG. 32 displays the control button functions shown in FIG. 31 on one control button. After being displayed all at once in this way, it can be realized that the device accepts the expression of the user's direction by touching the extent of the area in the desired direction.

If you want to display on one button only two control buttons with the character assigned to the character button located immediately to the left and the character button located immediately to the right of the character button to which the character entered immediately before (cursor) is assigned, , about the control button at the bottom of the display screen of FIG. 36 can be used. (Actually, the control button of FIG. 36 is used for a slightly different purpose from the control button described so far in the description of the embodiment using FIG. 36.)

32 or 33 is a control button in which the character assigned to the character button in the upper, lower, left, right, upper left, lower left, upper right, or lower right direction of the character button to which the character input immediately before (cursor) is assigned is the same control button It may be an embodiment for a control button displayed in .

That is, a specific spatial relationship is immediately left, immediately right, and immediately top , directly below, directly upper left , Immediately lower left , Immediately right side , or immediately lower right It can be defined and applied in various ways including any one or more of them.

So far, to put it simply by way of example,

On the control button for text change,

(Cursor) of the character button to which the character entered immediately before is assigned.

The case where the character assigned to the character button on the immediate left or right side is assigned has been described.

Now, to put it simply for example,

On the control button for text change,

Let's look at the case where other characters assigned to the character button to which the character input just before (cursor) is assigned are assigned.

<Delete: the old claim formula>

now

'realistically, one time by generating a signal,

In a method characterized in that the character input immediately before is replaced with a character having a specific relationship to the character

'character of a specific relationship'

' Among the characters assigned to the same button as the button to which the character entered immediately before was assigned, the character entered immediately before (spatial relationship or) A method of being a character having a specific relationship including a specific assignment order relationship' will be described through embodiments.

Even when a plurality of characters are assigned to the same button as in FIGS. 34, 37 or 39, when a typo occurs, as before, the user deletes the already entered characters including the characters input due to the typo without the process of deleting them. ,

(actually, by generating a single signal,)

I will explain how to replace the character with the original target.

34, 37, 38, or 39, when a plurality of characters are assigned to the same button,

Since the size of the text button is quite large, it is very rare to operate the wrong text button other than the original text button,

The text button, which was originally aimed at, was properly touched, but

In many cases, the wrong button operation causes the wrong character to be entered.

The reason for this has been briefly mentioned in the section 'Technology Background to the Invention', so it will not be mentioned again here.

However, only a method of replacing previously inputted characters including characters input due to typos to the original target characters without the user deleting the characters will be described.

First, let me explain with an example.

During the last process of inputting 'SO POOR' into the character input window of 'AREA-D' on the display screen as in FIG. 37, 38, or 39,

Until 'SO POO' was entered correctly (not shown), an attempt was made to input the last character, 'R'. If the assigned 'Q' is entered (after all, 'SO POOQ' is entered), the typo can be corrected in several ways as follows. (The following method 1 is recommended.)

1. As a control button at the bottom of the display screen as shown in FIG. 39, 'P, Q, R, In the state where there are control buttons to which 'P, R, S', which are characters excluding 'Q', which is the character input just before (cursor), are assigned (eg, displayed) among S'

If you press the control button to which 'R' is assigned (eg, display), 'Q' can be replaced with 'R' immediately.

(If it proceeds as above, now, on the control buttons

'PQRS', which is the character button to which 'R', the character entered immediately before (cursor) is assigned Characters 'P,Q,S' except for will be assigned (eg marked), and in that state

If you press the control button to which 'Q' is assigned (eg, displayed), you can make 'R' replaced with 'Q'.)

2. As a control button at the bottom of the display screen as shown in Fig. 38, 'P, Q, In the state where there are control buttons to which R, S' is assigned (eg, displayed),

If you press the control button to which 'R' is assigned (eg, display), 'Q' can be replaced with 'R' immediately.

(If that happens, now, on the control buttons

Control buttons to which 'P,Q,R,S', which are all the characters assigned to the 'PQRS' character button, which is a character button assigned to the character 'R', which is the character input immediately before (cursor), are assigned (eg, displayed) in the state

If you press the control button to which 'Q' is assigned (eg, display), you can make 'R' replaced with 'Q'.)

3. As a control button at the bottom of the display screen as shown in Fig. 37, 'P' is the assignment order (eg display order) of the characters assigned to the 'PQRS' character button to which the character 'Q' input immediately before (cursor) is assigned ,Q,R,S' to 'Q'

A control button that displays the letter 'P' assigned to the immediate left (= before), and

In the state that there is a control button to which the assigned letter 'R' is assigned (eg, displayed) to the right (= before),

If you press the control button where 'R' is displayed, you can also make 'Q' be replaced with 'R' directly.

(If it proceeds as above, now, on the control buttons

'PQRS' to which the character 'R' entered immediately before (cursor) is assigned

The letter 'Q' assigned to the immediate left (= before) is

The letter 'S' assigned immediately to the right (before =) will be assigned (eg, marked), and in such a state,

When the control button to which 'Q' is assigned (eg, displayed) is pressed, 'R' can be replaced with 'Q' directly.

Example 3 above

In the third step,

It can be said that the one or more characters identified in the second step are assigned to one or more control buttons of 'some (P, R)' rather than 'all (P, R, S)'.

Note that,

The first, second, and third embodiments in which Figs. 37, 38, and 39 are cited have a character button having only two numbers of characters assigned to the same button as in the keyboard shown in Fig. 34 or Fig. 36. The same can be applied to the keyboard.

In the last process of inputting 'SO GOOD' into the character input window of 'AREA-D' on the keyboard as in FIG. 34 or 36,

If you wanted to input 'D' as the last character, but you entered the 'F' assigned to the same character button as 'D' by mistake of button operation (after all, if 'SO GOOF' was entered), There are two ways to correct a typo. (The following method is recommended.)

1. As a control button at the bottom of the display screen as shown in FIG. 36, among the letters 'D, F' ( Cursor) In the state where there is a control button ('1 BUTTON' in Fig. 36) to which 'D', which is a character excluding 'F', which is input immediately before the cursor) is assigned (eg, displayed)

If you press the control button to which 'D' is assigned (eg, displayed), 'F' can be replaced with 'D' immediately.

(If it proceeds as above, now, on the control button

Characters other than 'D', which are the letters entered immediately before (cursor), among the letters 'D, F', which are assigned to the letter button 'DF' An 'F' will be assigned (eg marked), and in that state

If you press the control button to which 'F' is assigned (eg, displayed) ('1 BUTTON' in FIG. 36), 'D' may be replaced with 'F' immediately.)

(Since only two characters are assigned to the same button, there is no problem even if there is only one control button because there is only one remaining character other than the character entered immediately before.)

<Delete: became unnecessary>

In particular, in this case like Fig. Having just one control button wouldn't matter.

the reason example Let's explain it through:

Figure 36 When entering characters using the same keyboard,

' G' I tried to input , but due to a typo, ' H' is entered or

' H' I tried to input , but due to a typo, ' G' In both cases, 'G' is entered or H' If you simply press the control button displayed with like the examples , can be replaced immediately.

Because, since only two characters are assigned to the same button, the remaining characters other than the character entered immediately before there is only one Because.

2. As a control button at the bottom of the display screen as shown in FIG. 34, 'D, F', which is a character button assigned to the character button 'DF', to which the character 'F' input immediately before (cursor) is assigned In the state where there are control buttons assigned (eg, displayed)

If you press the control button to which 'D' is assigned (eg, displayed), 'F' can be replaced with 'D' immediately.

(If that happens, now, on the control buttons

(Cursor) In the state that there are control buttons to which 'D, F', which are all the letters assigned to the letter button, 'DF', which is the letter button to which 'D', which is the letter entered immediately before (cursor) is assigned, is assigned (eg, displayed)

If you press the control button to which 'F' is assigned (eg, display), you can make 'D' replaced with 'F'.)

<Delete: unnecessary>

That is, the function of the control button in the above embodiment performs a function of replacing the character input immediately before (cursor) with another character in the same button while moving the assignment order of the characters assigned to the assigned button. was stipulated to be However, you can create and apply another rule for the function of the arrow buttons.

Let's examine the meaning of the implied phrases claimed in the present application while reviewing Example 1 once again.

In the process for inputting 'SO POOR' into the character input window in 'AREA-D' of FIG. 39,

I tried to input the last character, 'R', in a situation where 'SO POO' was properly entered (not shown), but the 'PQRS' character button to which 'R' was assigned was operated incorrectly, and the wrong 'Q' was entered, That is, suppose that 'SO POOQ' has been input due to a typo in the character input window in 'AREA-D', as shown in FIG. .

When the above state is reached, the first step proceeds.

" Step 1: It is a step in which the character at the position derived by the position regulation in a specific relationship with the cursor position or state in the character input window is grasped ".

(in the first step,

It is recommended that the position derived by the position regulation in a specific relationship with the cursor position or state in the character input window is the position immediately before the cursor.)

In the first step phrase, 'a position derived by defining a position in a specific relationship with the cursor position and state' is the position immediately before the cursor in this embodiment.

(However, as in this embodiment, the position is up to pre-determining how far away from the cursor it is before and after the current cursor position as well as immediately before or immediately before and immediately after, as in this embodiment. )

In that case, after all, 'a character at a position derived by the position regulation (1) in a specific relationship with the cursor position and state' means a character to be changed in the future, and the character immediately before the cursor input due to a typo in this embodiment In, it is ' Q' .

(After all, in this embodiment, the 'character identified in the first step' is ' Q' . )

Also, depending on the cursor state, the 'position derived by the cursor position and state and the specific positional relationship rule (1)' may change.

In general, since the cursor state in portable electronic products including smartphones is in the INSERT mode on the desktop PC, in this embodiment it was the position just before the cursor, but if in the NOT INSERT mode on the desktop PC, the current cursor position itself is It would be most desirable to use the 'position derived by the cursor position and state and a specific relationship rule'.

(However, even in the NOT INSERT mode, the rules are up to pre-determining, including how far forward and backward the cursor is from the cursor, including just before, immediately after, immediately before, and immediately after the cursor.)

Also, suppose that the color of the 'PQRS' text button is displayed differently from other buttons as shown in FIG. 39 .

In this situation,

Conventionally, the user presses the delete button to delete the input 'Q' due to a typo, and input 'R', which was originally intended to be input, but

Herein, the user may change the 'Q' to 'R' without deleting the 'Q' input due to a typo. I will explain this in detail.

Step 2: Step of recognizing one or more characters excluding the character identified in the first step among two or more characters assigned to the character button on the keyboard to which the character identified in the first step is assigned

To explain the above two-step phrase, for example, with Fig. 39,

It has already been mentioned in the description of the first stage phrase that the 'character identified in the first step' is 'Q',

The 'character button on the keyboard to which the character identified in the first step is assigned'

Of course, it will be the 'PQRS' character button on the keyboard in 'AREA-E' of FIG.

' At least one character excluding the character identified in the first step among the two or more characters assigned to the character button on the keyboard to which the character identified in the first step is assigned '

' is a character that will be a candidate character to be changed to such a character in the future, and in this embodiment, the character ('Q') input immediately before (cursor) is assigned to the assigned character button (ie, 'PQRS' character button) It becomes 'P', 'R', 'S' except for 'Q' among P,Q,R,S'.

' Third step: a step in which one or more characters (any one or more characters) identified in the second step are assigned to one or more control buttons '

(in the third step,

All of the one or more characters identified in the second step are applied to the one or more control buttons. allotted recommend that

In the third step,

If one or more characters (any one or more characters) identified in the second step have been assigned to one or more control buttons, it is recommended to display them.)

In the third step, the word 'control button' appears for the first time, and the 'control button' can be said to be a button whose function is to change an already entered character to another character.

At the bottom of the display screen of FIG. 39, there are three control buttons '1 BUTTON', '2 Button', and '3 Button'. The character identified in step 2 is assigned to this control button(s).

That is, the characters assigned to the control button(s) are continuously changed as the cursor position and input are continued.

That is, in this embodiment, the characters 'P', 'R', or 'P', 'R', or 'S' is assigned.

And, in this embodiment, 'P', 'R', or 'S' assigned to the control button of FIG. 39 is displayed.

('P' is assigned and displayed on the control button called '1 BUTTON',

'R' is assigned and displayed on the control button called '2 BUTTON',

'S' is assigned to the control button '3 BUTTON' and displayed.)

For reference, the assigned character may or may not be displayed on the control button.

That the assigned character is displayed on the control button means that 'P', 'R', or 'S' is displayed on the control button of FIG. 39 as in this embodiment,

The fact that the assigned character is not displayed on the control button includes that only any pattern including an arrow indicating a direction may be displayed instead of the assigned character, and that the button display state may be blank.

Since the characters identified in the second step are expected to be relatively simple as in this embodiment in most cases where the technology of the present application is applied by someone in the future, it is predicted that there will be no major problem even if the display behavior of the control button is blank. Because, even if 'A' or 'D' is not displayed on the control button of FIG.

If the regulations for steps 2 and 3 are

(Cursor) of the characters assigned to the button ('PQRS' character button) to which the previously inputted character ('Q') is assigned (cursor)

If it is the rule that the character ('Q') entered immediately before (cursor) is assigned to the control button in the order of assignment (= mark) in the assigned button ('PQRS' character button),

'P' is assigned to the control button called '1 BUTTON',

'R' is assigned to the control button called '2 BUTTON',

This is because it is easy to know that 'S' will be assigned to the control button '3 BUTTON'. (An example of the behavior indicated by the arrow will be presented later.)

Step 4: Step in which any one of one or more control buttons is selected and the character assigned to the selected control button (or until displayed after assignment) is identified

To explain the above phrase through this embodiment, '1 BUTTON', '2 BUTTON' to which 'P', 'R', or 'S' is assigned, which is the control button to which the letter in step 3 is assigned, If you touch and select the control button ('2 BUTTON' in FIG. 39) marked with 'R' among the control button(s) called '3 Button', the character assigned to the selected control button is, of course, 'R'. will be figured out

Step 5: A step in which the character identified in the first step is changed to the character identified in the fourth step.

To explain the above phrase through this embodiment, the letter 'Q' identified in step 1 is changed to 'R', which is the letter identified in step 4.

To explain a little more, due to a typo in AREA-D of FIG. 39, input 'Q' can be replaced with 'R' (after all, 'SO POOQ' will be changed to 'SO POOR'. (not shown) city))

That is, it is not a concept in which the user inputs 'R' after deleting 'Q' as in the prior art.

In the fifth step,

The process of changing the character identified in the first step to the character identified in the fourth step is

The character identified in the first step may be directly changed to the character identified in the fourth step, or the character identified in the fourth step may be input after the character identified in the first step is deleted.

To explain the above phrase through this example,

In the above, the method of the present application merely changes the character input due to a typo (eg 'Q') to the originally targeted character (eg 'R'), but it is said that it is the user's conception or visual easy,

In terms of electronic technology,

When you touch the control button ('1 BUTTON' in FIG. 39) marked with 'R' at the bottom of the display screen of FIG. 39,

It can be implemented so that 'Q' is directly replaced with 'R',

Alternatively, 'Q' may be deleted almost instantly and 'R' may be input so that 'Q' appears to be replaced with 'R' in the eyes of the user without the process of deleting 'Q'.

above example The following is a summary of the accompanying explanations.

In a device for inputting characters through the keyboard (in the method of correcting the character entered just before due to a typo)

(without the step of substantially deleting the character immediately entered by the user)

realistically, one time by generating a signal,

A method characterized in that the character input immediately before is replaced with a character having a specific relationship to the character.

In

'Character of a specific relationship' is

' Among the characters assigned to the same button as the button to which the character entered immediately before is assigned, a character having a specific relationship with the character input immediately before, including a specific spatial relationship or a specific assignment order relationship ' can be a way of being.

in front In the embodiment Although only a specific assignment order relationship has been described, it may be a specific spatial relationship.

E.g, 17 in FIG. The form in which P, Q, R, S is assigned can also be said to be assigned so that it is easy to know what order each character is assigned. as in Fig. If it is not marked and it is marked in four directions: up, down, left, right, it becomes a specific spatial relationship, Figure 11 display screen You may need the up, down, left and right buttons at the bottom. or of Figure 13 display screen Bottom top, bottom, left, right, top left, lower left , idol, or right Directional control buttons may be required. Of course, each direction button may be disposed separately.

(Not necessary here where text is displayed on the control button)

So, the abbreviated phrase above can be modified a little more specifically as follows.

' Among the characters assigned to the same button as the button to which the character entered immediately before is assigned, a character having a specific relationship with the character input immediately before, including a specific spatial relationship or a specific assignment order relationship, is

Among the characters assigned to the same button as the button to which the character entered immediately before

The position in which the characters assigned to the same button as the button to which the character entered immediately before is assigned are assigned to that button, or in the order assigned to the button

A method characterized in that the character input immediately before is a character having a specific relationship with the assigned position or order'

And, the rules for the relationship between the cursor position and the character position modified by the new character are up to the decision.

As in the previous embodiments, the character input immediately before the current cursor position may be corrected through the character correction control button,

The character input immediately before the character input immediately before the current cursor position can be modified through the character edit control button,

than the character entered just before the current cursor position. 2 characters It is also possible to modify the text entered first through the text edit control button,

The character input immediately after the cursor position) can be modified through the character edit control button,

The character input immediately after the character input just before the current cursor position can be modified through the character edit control button,

than the character entered just before the current cursor position. 2 characters Including that the characters entered later can be modified through the character edit control button,

It is up to you to determine the rules for the relationship between the cursor position and the character position to be modified by manipulating the character edit control button.

As in the previous embodiments, the character input just before the current cursor position is changed through the character correction control button. to be corrected is most recommended

Therefore, the 'character input immediately before' mentioned above can be described more comprehensively by replacing it with 'character at a prescribed position related to the current cursor position'.

In the description of 'third step: the step in which one or more characters identified in the second step are assigned to one or more control buttons' in the above,

At least one character value identified in step 2 is

It said that it may or may not be displayed on the control button,

so far

It has been described with only the examples shown.

From now on, I will briefly explain that a method in which characters are not displayed on the control buttons including the control buttons with arrows instead of on the control buttons is also possible.

Literally, it is the same as the embodiment when displayed above until one or more character values identified in the second step are assigned to the control button. The process up to that point is the same.

Therefore, in the drawings cited in the above embodiment, only the drawings in which the characters displayed on the control buttons are changed to arrows are substituted for the above embodiments and descriptions and interpreted according to the situation, it will be easy to understand without detailed explanation.

Therefore, the drawings in which the text is displayed on the control button cited in the above embodiment and the drawing in which the text is changed to an arrow will be introduced pairwise as follows.

For the embodiment in which the drawings are cited in the case where the control button is not displayed as characters in the drawings paired above, description is not likely to be necessary, but it will be described briefly.

4 is a diagram of an embodiment of a smart phone equipped with a virtual keyboard on a touch screen to which the technology of the present application is applied. Compared to the conventional general smartphone virtual keyboard as shown in Fig. 1, at the bottom of Fig. 4, a left-direction arrow is indicated on the control button ('LEFT BUTTON' in Fig. 4) and a right-direction arrow is indicated on the control button ('RIGHT in Fig. 4). BUTTON').

[In fact, if the technology of the present application is applied to a smartphone, in a conventional smartphone drawing such as FIG.

As shown in Fig. 3, the shift button and the delete button are moved to the bottom, and as a control button for applying the technology of the present application, a control button with a left-direction arrow ('LEFT Button' in Fig. 3) and a right-direction arrow are displayed. A layout in which the button ('RIGHT BUTTON' in Fig. 3) is positioned in the place of the conventional shift button and the delete button, or

As shown in FIG. 20, the positions of the shift button and the delete button are the same as in the prior art, but as a control button for applying the technology of the present invention, a control button with a left arrow ('LEFT Button' in FIG. 20) and a control button with a right arrow ('RIGHT BUTTON' in Fig. 20) is placed next to the conventional space button.

It is judged to be better, but in order to improve unity and understanding with those that will be described later various embodiments, the description will be made based on FIG. 4 ]

First, in order to apply the technology of the present application as much as possible comfortably to the user, it is recommended that the starting point of the application of the present technology be implemented slightly differently from the conventional technology as follows.

The conventional technology applied to Samsung Electronics' Galaxy S described in the 'Technology Background to the Invention' section is briefly described once again.

When a certain letter button (eg, 'D' letter button) is being touched, as shown in FIG. 2, the color of the letter button changes color differently from other buttons, and a large pop-up is formed directly above the button,

When a touch on a certain text button is released, the pop-up disappears, and the color of the text button touched just before is returned to the same color as other buttons.

However, when the technology of the present application is applied, when the display for the touched button starts to be implemented slightly differently from the prior art as follows, when the technology of the present application is further advanced later, the user can clearly determine what character button the button touched just before It will be possible to make a decision, and it will be more convenient for the user. (However, even if it starts to be implemented in the same way as in the prior art, there is no problem in implementing the technology of the present application.)

In a little more detail, when applying the technology of the present application,

When a certain text button is being touched, the color of the text button changes color differently from other buttons, and a large pop-up is formed just above the button,

When the touch of a certain text button is released, it is the same as the prior art until the pop-up disappears. The color of the text button that was touched just before is maintained as it is, in a different color from other buttons, and when a new button is touched, another button It is recommended to have the same color as the field.

(However, in fact, it would have been better if it had been implemented in the method recommended herein in the prior art. Because, in the prior art, the pop-up formed in the immediate vicinity of the touched character button disappears as soon as the touch of the finger on the character button is released. , And, in actual use, since the touch time is very short, it is also difficult to accurately recognize the text displayed in the pop-up.)

The following process is also performed on the assumption that the technology of the present application is applied in the above manner.

4, in the process for inputting 'SO GOOD' into the character input window in 'AREA-D' of FIG. 4,

Until 'SO GOO' was entered correctly (not shown), an attempt was made to input the last character 'D', but after the wrong 'S' character button was touched, the touch of the finger was released, so as in Figure 5, 'AREA- Assume that 'S' is input in the character input window in D', and the cursor is positioned immediately after 'S' entered as a typo like 'AREA-D' in FIG. 5 .

And, suppose that the color of the 'S' letter button is displayed differently from other buttons as shown in FIG. 5. (After all, 'SO GOOS' has been input.)

In this situation,

In the past, ' that was entered due to a typo S' is deleted by the user pressing the delete button, and the ' that was originally intended to be entered D' entered, but

In this application, the ' entered due to a typo S' without the user deleting ' S' cast ' D' can be changed to

For example, to explain with reference to Figures 5 and 6,

At the bottom of the display screen of Figure 5,

of the button (that is, the 'S' letter button) to which the immediately preceding letter ('S') is assigned.

'A' assigned to the letter button ('A' letter button) on the left is assigned to the control button ('LEFT BUTTON' in FIG. 5) marked with a left arrow,

'D''D' assigned to the letter button ('D' letter button) on the right side is assigned to the control button ('RIGHT BUTTON' in FIG. 5) marked with an arrow pointing to the right,

By touching the control button marked with a right arrow ('RIGHT BUTTON' in Fig. 5), the 'S' input due to a typo in AREA-D in Fig. 5 can be replaced with 'D' as shown in Fig. 6. Eventually , was entered as 'SO GOOD'.

(Or, in the user's conception, the color of the 'S' character button that is currently incorrectly touched as in FIG. 5 is moved to the 'D' character button that was originally intended to be input as shown in FIG. 6, and the display screen of FIG. By touching the control button ('RIGHT BUTTON' in Fig. 5) marked with a right arrow at the bottom, the 'S' entered due to a typo in Fig. 5 AREA-D can be replaced with 'D' as shown in Fig. 6. there is.)

That is, it is not a concept in which the user inputs 'D' after deleting 'S' as in the prior art.

(And, in the description of the technical embodiment of the present application, the color of the 'S' letter button was originally attempted to be input as shown in FIG. You may think of moving to the 'D' letter button, but like the conventional color transformation method, the technology of the present invention can also be implemented by returning the same color to other buttons as soon as the touch is released. can't change, traditional desktop The typo correction method of this company will not have much effect, but it can be applied to the PC's physical keyboard.)

In the above, the method of the present application was only described as a technology for directly replacing an input character (eg, 'S') with a character (eg, 'D') that was originally targeted due to a typo, but it That's what I mean,

In terms of electronic technology,

When you touch the control button ('RIGHT BUTTON' in FIG. 5) marked with a right arrow at the bottom of the display screen of FIG. 5,

It can be implemented so that 'S' is directly replaced with 'D',

Alternatively, it can be implemented so that 'S' is (automatically) deleted almost instantly, 'D' is entered, and eventually 'S' is replaced with 'D'.

Let's take another embodiment to better understand the technology of the present application, including making it clear that the character assigned to the control button can be changed.

In the process for inputting 'SO GOOD' into the character input window as shown in Figure 4,

I tried to input 'D', the last character, in a situation where 'SO GOO' was properly entered (not shown), but after the wrong 'F' character button was touched, the touch of my finger was released, so as in FIG. 7, 'AREA' Assume that 'F' is input in the character input window at -D', and the cursor is positioned immediately after 'F' entered as a typo like 'AREA-D' in FIG. 7 .

And, suppose that the color of the 'F' letter button is displayed differently from other buttons as shown in FIG. 7 (after all, 'SO GOOF' is inputted).

In this situation, in the prior art, the user deleted the input 'F' due to a typo and input the 'D' that was originally intended to be input . You can change ' F' to ' D' .

For example, to explain with reference to Figures 6 and 7,

The button to which the character ('F') entered immediately before is assigned (that is, the 'F' character button)

The 'D' assigned to the letter button ('D' letter button) on the right side is assigned to the control button ('LEFT BUTTON' in FIG. 7) marked with an arrow pointing to the left,

The 'G' assigned to the character button ('G' character button) on the right side is assigned to the control button ('RIGHT BUTTON' in FIG. 7) marked with an arrow pointing to the right,

By touching the control button ('LEFT BUTTON' in Fig. 7) marked with a left arrow, 'F' input due to a typo in AREA-D in Fig. 7 can be replaced with 'D' as shown in Fig. 6. Eventually , was entered as 'SO GOOD'.

(Or, in the user's conception, the color of the 'F' character button that is currently incorrectly touched as shown in FIG. 7 is moved to the 'D' character button that was originally intended to be input as shown in FIG. 6, and the display screen of FIG. Touch the control button ('LEFT BUTTON' in FIG. 7) marked with a left arrow at the bottom to replace the 'F' entered as a typo in 'AREA-D' in FIG. 7 with 'D' as shown in FIG. can be discarded.)

That is, it is not a concept of inputting 'D' after deleting 'F' as in the prior art.

<Delete: Deletes duplicates except for alphabets>

In the above, the method of the present application is a character input due to a typo (eg, ' F' ) was originally targeted (e.g. ' D' ), but it is said that it is a technology that replaces

In terms of electronic technology,

of Figure 7 of the display screen The control button with the left arrow at the bottom ( of Figure 7 ' LEFT BUTTON' ) is touched,

' F' go ' D' It can be implemented to be replaced directly with

Alternatively, it could be implemented so that 'F' is (automatically) deleted almost instantly , 'D' is entered, and eventually ' F' is replaced with ' D' .

Of course, the technology of the present disclosure may be applied while moving the cursor position.

For example, an already input character including a character input due to a typo may be replaced with a new character including the originally targeted character without a step of the user deleting the character input immediately before the moved cursor position.

<Delete: unnecessary>

(For reference, in the examples so far, when the cursor is displayed, an English capital letter ' L' lowercase letter of ' l' I didn't mark it because I thought it would be confusing.)

For example, in the state in which 'SO GOOD' is input, the cursor is moved by the user to be positioned between 'S' and 'O' of 'SO' as shown in FIG. 42,

If the 'position derived by the position regulation (1) of a specific relationship with the position or state of the cursor in the text input window' in the first step is 'the position immediately before the cursor',

The characters identified in 'Step 1: Step in which the character at the position derived by the position regulation (1) in a specific relationship with the cursor position or state in the character input window is grasped'

becomes 'S',

'A' assigned to the letter button (='A button') located on the left side of the 'S letter button' is assigned to the control button ('LEFT BUTTON' in FIG. 42) marked with a left arrow,

'D' assigned to the character button (='D button') located on the right side of the 'S letter button' is assigned to the control button ('RIGHT BUTTON' in FIG. 42) marked with a right arrow, in that state, By touching the control button marked with 'A' ('LEFT BUTTON' in FIG. 42), 'S' can be replaced with 'A'. (After all, 'AO GOOD' is input (not shown)). )

------------------------------------------------------------ --------------------<Delete: Plot is virtually duplicate>:

A brief summary of the above few paragraphs:

Replacing previously entered characters including characters entered due to typos with new characters including originally targeted characters without “substantially” deleting the characters previously entered by the user can say that

The word “substantially” above means

As explained in the previous few paragraphs

Characters entered due to a typo (eg ' F' ) was originally targeted (e.g. ' D' ), literally, can be directly replaced with,

Characters entered due to a typo (eg ' F' ), without the user giving a separate deletion command, the original target character (eg, ' D' ) by touching the assigned control button,

Characters entered due to a typo (eg ' F' ) is momentarily deleted, and then the originally targeted character (eg, ' D' ) is entered,

Characters entered due to a typo (eg ' F' ) was originally targeted (e.g. ' D' ), including meanings that can have the effect of replacing them.

As in the above embodiment, in the virtual keyboard that appears when inputting text with a vertical smartphone in the prior art, since the horizontal length of each letter button is in a rectangular shape elongated in the vertical direction less than the vertical length, in most cases, a typo In many cases, the occurrence is caused by erroneously touching a character button located immediately to the left or right of the originally targeted button.

Therefore, when the technology of the present application is applied to the virtual keyboard as shown in Fig. 1, which appears most frequently when inputting text with the smartphone standing vertically, the original target was to As a control button necessary to change to a new character including a character, a control button marked with a left-direction arrow or a right-direction arrow as shown in FIG. 3 or FIG. 4 will be sufficient.

However, when the horizontal length of each letter button is greater than the vertical length as shown in FIG. 9, that is, since each letter button has a rectangular shape that is elongated from side to side, in most cases, a typo occurs right above or directly above the originally targeted button. In many cases, it will be caused by mistakenly touching the character button located in the lower direction.

In the case of applying the technology of the present invention to a keyboard when the horizontal length of each character button including FIG. 9 is greater than the vertical length, the previously input characters including the characters input due to a typo are new, including the originally targeted characters. As a control button required to change to a character, as shown in FIG. 10, a control button marked with an upward arrow or a downward arrow will be sufficient.

If a left arrow, a right arrow, an upward arrow, and a downward arrow are also necessary, control buttons may be provided as shown in FIG. 11 .

The control button shown in Fig. 12 is a button in which the arrows in the four directions shown in Fig. 11 are displayed on one button. After being displayed all at once in this way, it can be realized that the device accepts the expression of the user's direction by touching the area of the arrow head in the desired direction.

If it is desired to display only the left arrow and the right arrow on one button at the same time, the control button at the bottom of the display screen of FIG. 16 may be used. (Actually, the direction display control button of FIG. 16 is used for a slightly different purpose from the control button described so far in the description of the embodiment using FIG. 16.)

A little more detailed explanation of the above abbreviated contents is as follows.

That is, a specific spatial relationship is immediately left, immediately right, and immediately top , directly below, directly upper left , Immediately lower left , Immediately right side , or immediately lower right It can be defined and applied in various ways including any one or more of them.

So far, to put it simply by way of example,

On the control button for text change,

The case where the character assigned to the character button on the immediate left or right side is assigned has been described.

Now, to put it simply for example,

On the control button for text change,

Let's look at a case where other characters assigned to the character button to which the character input just before (cursor) is assigned are assigned.

<Deleted: Old claim formula>

now

'realistically, one time by generating a signal,

In a method characterized in that the character input immediately before is replaced with a character having a specific relationship to the character

'character of a specific relationship'

' Among the characters assigned to the same button as the button to which the character entered immediately before was assigned, the character entered immediately before (spatial relationship or) A method of being a character having a specific relationship including a specific assignment order relationship' will be described through embodiments.

Even when a plurality of characters are assigned to the same button as in FIG. 14, 17, or 21, when a typo occurs, the user deletes the already input characters including the characters input due to the typo as before. without, substantially, generating a single signal,

I will explain how to replace the character input just before with the character that was originally targeted.

14, 17, 18, or 21, when a plurality of characters are assigned to the same button,

Since the size of the text button is quite large, it is very rare to operate the wrong text button other than the original text button,

The text button, which was originally aimed at, was properly touched, but

In many cases, the wrong button operation causes the wrong character to be entered.

The reason for this has been briefly mentioned in the section 'Technology Background to the Invention', so it will not be mentioned again here.

However, I will only explain a method of replacing previously entered characters, including those entered due to typos, with the originally targeted characters without the user deleting them.

First, let me explain with an example.

During the last process of inputting 'SO POOR' into the character input window of 'AREA-D' on the display screen as shown in FIG. 17, or FIG. 18 or 21,

Until 'SO POO' was entered correctly (not shown), an attempt was made to input the last character, 'R'. If the assigned 'Q' is entered (after all, if 'SO POOQ' is entered), the typo can be corrected in several ways as follows. (The following method 1 is recommended.)

1. As a control button at the bottom of the display screen as shown in FIG. 21, the character input immediately before among 1, 2, 3, 4 which means the order of assignment of the characters assigned to the character button to which the character input immediately before is assigned In the state where there is a control button displaying the numbers 1, 3, 4 except for 2, which is the assignment order of

When control button number 3 is pressed, 'Q' may be directly replaced with 'R', which is the third assigned character among the characters assigned to the button to which 'Q' is assigned.

Let us explain the above phrase in detail as follows.

As a control button at the bottom of the display screen as shown in FIG. 21, 'P, Q, R, S', which is a character assigned to a character button, 'PQRS', which is a character button to which 'Q', which is a character input immediately before (cursor), is assigned (If the assignment order is expressed as a number, P=1, Q=2, R=3, S=4) of the characters 'P,R,S' (assignment order) If is expressed as a number, P=1, R=3, S=4) is

They are assigned to the control buttons, and to mention the assignment situation in detail,

'P' is assigned to the control button marked '1' ('A BUTTON' in FIG. 21),

'R' is assigned to the control button marked '3' ('B BUTTON' in FIG. 21),

'S' is assigned to the control button marked '4' ('C BUTTON' in FIG. 21).

In this state, if the control button marked with '3' to which 'R' is assigned is pressed, 'Q' can be directly replaced with 'R'.

(If it proceeds as above,

(Cursor) 'PQRS', which is the character button to which 'R', the character entered immediately before, is assigned, 'P,Q,R,S', which is the character assigned to the character button 2, R=3, S=4) of the characters 'P,Q,S' except for 'R', which is the character input just before the (cursor), (P=1, R=2, S =4) is

They are assigned to the control buttons, and to mention the assignment situation in detail,

'P' is assigned to the control button marked '1' ('A BUTTON' in FIG. 21),

'Q' is assigned to the control button marked '2' ('B BUTTON' in FIG. 21),

'S' is assigned to the control button marked '4' ('C BUTTON' in FIG. 21).

In this state, if you press the control button marked '2' to which 'Q' is assigned, 'R' can be replaced with 'Q'.)

2. As a control button at the bottom of the display screen as shown in FIG. 18, there is a control button with 1,2,3,4 indicating the order of assignment of the characters assigned to the character button to which the character input immediately before is assigned in

When control button number 3 is pressed, 'Q' may be directly replaced with 'R', which is the third assigned character among the characters assigned to the button to which 'Q' is assigned.

Let us explain the above phrase in detail as follows.

As a control button at the bottom of the display screen as shown in FIG. 18, 'P, Q, R, S', which is a character assigned to a character button, 'PQRS', which is a character button to which 'Q', which is a character input immediately before (cursor), is assigned (If the assignment order is expressed as a number, P=1, Q=2, R=3, S=4)

They are assigned to the control buttons, and to mention the assignment situation in detail,

'P' is assigned to the control button marked '1' ('A BUTTON' in FIG. 21),

'Q' is assigned to the control button marked '2' ('B BUTTON' in FIG. 21),

'R' is assigned to the control button marked '3' ('C BUTTON' in FIG. 21),

'S' is assigned to the control button marked '4' ('D BUTTON' in FIG. 21).

In this state, if the control button marked with '3' to which 'R' is assigned is pressed, 'Q' can be directly replaced with 'R'.

(If it proceeds as above,

(Cursor) 'PQRS', which is the character button to which 'R', the character entered immediately before, is assigned, 'P,Q,R,S', which is the character assigned to the character button 2, R=3, S=4) all

They are assigned to the control buttons, and to mention the assignment situation in detail,

'P' is assigned to the control button marked '1' ('A BUTTON' in FIG. 21),

'Q' is assigned to the control button marked '2' ('B BUTTON' in FIG. 21),

'R' is assigned to the control button marked '3' ('C BUTTON' in FIG. 21),

'S' is assigned to the control button marked '4' ('D BUTTON' in FIG. 21).

In this state, if you press the control button marked '2' to which 'Q' is assigned, 'R' can be replaced with 'Q'.)

3. As a control button at the bottom of the display screen as shown in Fig. 17, in a state where there are control buttons marked with left and right arrows

When the control button marked with a right arrow is pressed once, the 'PQRS' character button, which is the same character button as the character button assigned to 'Q', is replaced with 'R' displayed (=assigned) immediately to the right of 'Q' it can also be made

(If the control button marked with a right arrow is pressed twice, 'Q' will be replaced with 'S' assigned second to the right of 'Q'.)

(The function of the control button indicated by the arrow in the above embodiment is that the character input immediately before the (cursor) is replaced with another character in the same button while moving the assignment order of the characters assigned to the assigned button It can also be interpreted as defined as performing a function.)

The above phrase will be described in detail as follows.

As a control button at the bottom of the display screen as shown in FIG. 17, 'P,Q' which is the assignment order (eg, display order) of the characters assigned to the 'PQRS' character button to which the character 'Q' input immediately before (cursor) is assigned ,R,S' to 'Q'

A control button marked with a left arrow to which the letter ('P') assigned to the immediate left (= before) is assigned, and

In the state that there is a control button marked with a right arrow to which the assigned letter ('R') is assigned immediately to the right (= before),

If you press the control button that displays the right arrow to which 'R' is assigned, 'Q' can be replaced with 'R'.

(If it proceeds as above, now,

'PQRS' to which the character 'Q' entered immediately before (cursor) is assigned

A control button marked with a left arrow to which the character ('Q') assigned to the immediate left (= before) is assigned, and

In the state that there is a control button marked with a right arrow to which the assigned letter ('S') is assigned immediately to the right (= before),

If you press the control button that displays the right arrow to which the 'Q' is assigned, the 'R' can be replaced with 'Q'.)

Example 3 above

In the third step,

It can be said that the case is assigned to one or more control buttons of 'some (P, R)' rather than 'all (P, R, S)' of one or more characters identified in the second step.

Also, as shown in FIG. 19, the control buttons of FIGS. 17 and 18 may be disposed at the same time.

Also, the embodiment described above with reference to FIGS. 17 and 18 can be applied as it is to a keyboard having only one or two characters assigned to the same button as in FIGS. 14 and 16 . In particular, in this case, it will not matter even if there is only one control button as shown in FIG. 16 .

The reason for this will be explained through examples as follows.

In the case of inputting characters using the keyboard as shown in Fig. 16,

If you tried to input 'G', but 'H' was entered due to a typo, or

You tried to input 'H', but in both cases, when 'G' was entered due to a typo, just press the control button marked with a double-headed arrow, As in the above embodiments, new characters including the targeted characters can be replaced immediately.

This is because, since only two characters are assigned to the same button, there is only one character other than the character input immediately before.

Note that,

The first, second, and third embodiments, in which FIGS. 17, 18, and 21 are cited, are character buttons having only two numbers of characters assigned to the same button as in the keyboards of FIGS. 14, 15, and 16. It can be applied to existing keyboards as it is.

During the last process of inputting 'SO GOOD' into the character input window of 'AREA-D' on the keyboard as in FIG. 14 or 16,

If you wanted to input 'D' as the last character, but you entered the 'F' assigned to the same character button as 'D' by mistake of button operation (after all, if 'SO GOOF' was entered), There are two ways to correct a typo. (The following method is recommended.)

1. As a control button at the bottom of the display screen as shown in FIG. 16, among the letters 'D, F' ( Cursor) In the state where there is a control button marked with a left and right arrow to which a letter 'D' is assigned except for the character 'F' entered immediately before

When the control button assigned with 'D' is pressed, 'F' can be directly replaced with 'D'.

(If it proceeds as above, now, on the control button

Characters other than 'F', the character input immediately before (cursor), among the characters assigned to the character button 'DF', 'DF' 'F' will be assigned, in that state

If you press the control button marked with the left and right arrows to which 'F' is assigned, you can have 'D' replaced with 'F'.)

(Since only two characters are assigned to the same button, there is no problem even if there is only one control button because there is only one remaining character other than the character entered immediately before.)

<Delete: became unnecessary>

In particular, in this case like Fig. Having just one control button wouldn't matter.

the reason example Let's explain it through:

Figure 36 When entering characters using the same keyboard,

' G' I tried to input , but due to a typo, ' H' is entered or

' H' I tried to input , but due to a typo, ' G' In both cases, 'G' is entered or H' If you simply press the control button displayed with like the examples , can be replaced immediately.

Because, since only two characters are assigned to the same button, the remaining characters other than the character entered immediately before there is only one Because.

2. As a control button at the bottom of the display screen as shown in Fig. 14, 'F', which is the letter input immediately before (cursor), is assigned to 'DF', which is the letter button 'D, F' is assigned to two control buttons,

'D' is assigned to the control button marked with a left arrow,

'F' is assigned to the control button indicated by the right arrow.

At this time, if the control button to which 'D' is assigned (eg, displayed) is pressed, 'F' can be directly replaced with 'D'.

(If so, now,

(Cursor) All the characters assigned to the character button 'DF' to the character button 'D' to which 'D', which is the previously entered character, are assigned to the two control buttons,

'D' is assigned to the control button marked with a left arrow,

'F' is assigned to the control button indicated by the right arrow.

At this time, if the control button to which 'F' is assigned (eg, displayed) is pressed, 'D' can be replaced with 'F' immediately.

on the control buttons

Fig. 15 is substantially the same as Fig. 14 in content.

only,

The control button marked with the left arrow in FIG. 14 is changed to the control button marked with '1',

The control button marked with a right arrow in FIG. 14 is changed to a control button marked with '2'. That is, only the pattern displayed on the control button has changed.

above example The following is a summary of the accompanying explanations.

In a device for inputting characters through the keyboard (in the method of correcting the character entered just before due to a typo)

(without the step of substantially deleting the character immediately entered by the user)

realistically, one time by generating a signal,

A method characterized in that the character input immediately before is replaced with a character having a specific relationship to the character.

In

'Character of a specific relationship' is

' Among the characters assigned to the same button as the button to which the character entered immediately before is assigned, a character having a specific relationship with the character input immediately before, including a specific spatial relationship or a specific assignment order relationship ' can be a way of being.

in front In the embodiment Although only a specific assignment order (= marked order) relation has been described, it may be a specific spatial relation.

E.g, 18 in FIG. The form in which P, Q, R, S is assigned can also be said to be assigned so that it is easy to know what order each character is assigned. as in Fig. 18 From left to right for easy understanding of the assigned order PQRS' If it is not expressed as an expression and is marked in four directions, up, down, left, and right, even on the same control button, it becomes a specific spatial relationship, Figure 11 display screen You may need a control button marked with up, down, left and right arrows at the bottom. or of Figure 13 display screen Bottom top, bottom, left, right, top left, lower left , idol, or right Control buttons with directional arrows may be required. Of course, each direction button 11 like They may be disposed separately.

So, the abbreviated phrase above can be modified a little more specifically as follows.

' Among the characters assigned to the same button as the button to which the character entered immediately before is assigned, a character having a specific relationship with the character input immediately before, including a specific spatial relationship or a specific assignment order relationship, is

Among the characters assigned to the same button as the button to which the character entered immediately before

The position in which the characters assigned to the same button as the button to which the character entered immediately before is assigned are assigned to that button, or in the order assigned to the button

A method characterized in that the character input immediately before is a character having a specific relationship with the assigned position or order'

The text input method described so far can be applied regardless of any language in the world other than the mentioned languages. For example, it is applicable to Greek/Roman script, Cyrillic script, Arabic script, Southeast Asian script, Indian script, Thai script mode, Vietnamese script mode, and detailed languages English, French, German, Spanish, etc.

And, although the method of the present application has been described by giving only an example of correcting an error caused by wrongly touching a text button, it can be applied to a function button other than a text button.

Examples of function buttons include a text mode switch button, an environment setting button, a voice input mode button, and a delete button.

And, until now, a method of changing an already input character including a character input due to a typo into a new character including an originally intended character has been studied.

From now on, let's look at how the user can easily distinguish which button was operated just before, which was mentioned a little above.

To put a very simple example,

In input mode where only single touch is used ,

(When the first button is touched,

A button that has been displayed distinctly from two or more other buttons before the first button is touched is displayed indistinguishably from one or more buttons that are neither the button nor the first button)

The button that was touched just before (eg, the first button),

-Until another new button (eg, the second button) is touched, it is displayed to be distinguished from other buttons (eg, a different color);

-After a new button (eg, second button) is touched, it is displayed indistinguishably from other buttons (except for the second button) (eg, in the same color).

(Of course, the second button may be the same button as the first button.)

(To put it a little more simply:

The first button, which is the button that was touched just before,

Until the second button, which is another new button, is touched,

Displayed distinctly from one or two or more other buttons;

After the second button, which is another new button, is touched, it is displayed indistinguishably from one or two or more other buttons except for the second button.)

In the input mode where multi-touch is used to touch multiple buttons or multiple touch points using two or more fingers,

(When the first target button is recognized,

A button that was displayed to be distinguished from two or more other buttons before the first target button was touched is displayed indistinguishably from one or more buttons that are neither the button nor the first target button)

The target button (eg, the first target button) recognized in the previous touch,

-Until a new single-touch or multi-touch is initiated (or until another target button (eg, second target button) recognized in the new single-touch or multi-touch is recognized), to be distinguished from other buttons (eg: marked in different colors),

-After a new single touch or multi-touch is launched (or after another target button (eg, second target button) recognized in the new single touch or multi-touch is recognized), the same color as the other buttons is displayed.

(Of course, the button touched by the new single touch or the second target button may be the same target button as the first target button)

(To put it a little more simply,

In input mode used up to multi-touch ,

The first target button, which is the target button recognized in the previous touch,

Until a new single-touch or multi-touch is launched, or until a second target button that is another target button recognized in the new single-touch or multi-touch is recognized,

Displayed distinctly from one or two or more other buttons;

After a new single touch or multi-touch is initiated or after the second target button, which is another target button recognized in the new single touch or multi-touch, is recognized,

It is a button display method in an electronic device, characterized in that one or two or more other buttons are displayed indistinguishably except for the first target button.)

In the present application, the method of displaying a specific button to be distinguished from other buttons is not only a method of differentiating the color presented in the embodiment of the present application, but also

shape, color (hue, brightness, saturation), illuminance, luminance, luminance, luminous flux, luminous flux, or radiant flux or

Variation of any one or more of the above elements is also included.

For example, you can make it blink by changing the illuminance, make it smaller after the button is enlarged, and make only the text inside the button grow bigger.

Anything that can visually distinguish a key from another key is included.

In the present application, the meaning of 'button' in the phrases meaning that a specific button is displayed to be distinguished from other buttons does not only mean an area inside the button, but also includes an exterior immediately adjacent to the button.

For example, like the 'N' character button of FIG. 48, the 'N' character button may be of a different color (eg, gray) to be distinguished from the periphery of the other buttons (eg, white).

(Of course, like the 'N' character button of FIG. 46, only the inside of the 'N' character button may be of a different color (eg, gray) to distinguish it from the inside of other buttons.

Of course, only the outside of the 'N' letter button may be of a different color (eg, gray) to be distinguished from the outside of other buttons.

The above concept will be explained in the following through implied phrases and examples.

In order to better understand the implied phrases,

As if, the keyboard of the embodiment will be described in such a way that it feels as if there is only a character button capable of inputting only three characters 'D, N, O'.

(Slightly, it is easier to understand if it is explained with the concept of a keyboard with more than 26 buttons, but since the prerequisite of the implied phrase is a device with more than 3 buttons, it is possible to input only 3 characters. If you describe it to feel like a keyboard with only letter buttons, it's a bit confusing, but it's better for understanding the implications.

This is because if there are only three letter buttons, the roles of one button that was touched just before and the other two buttons can be faithfully shared.)

First, it is an input mode in which only single-touch touch with one finger is used, and as soon as it is touched, A case of a system in which a touched button is displayed to be distinguished from other buttons will be described.

Step A1: A step in which a touch on the first button is initiated.

For example, to explain

(As the 'O' character button was touched just before as shown in FIG. 44, the 'O' character button may have been displayed in a different color (eg, gray) to distinguish it from other buttons (eg, 'D, N' character button). there is,)

At this time, as shown in FIG. 45, a touch on the 'D' letter button, which is the first button, is initiated.

Step A2: The first button to be touched A button that has been previously displayed to be distinguished from two or more other buttons is displayed indistinguishably from one or more buttons that are neither the button nor the first button;

A step in which the first button is displayed to be distinguished from two or more buttons other than the first button.

For example, to explain

As in Figure 45,

Before the first button 'D' letter button was touched, the button 'O', which was displayed in a different color (eg gray), to distinguish it from two or more other buttons ('D, N' letter buttons), It is displayed in the same color (eg white) to be indistinguishable from one or more buttons (eg, 'N' character button) that are neither the 'O' button, which is a button, nor the 'D' letter button, which is the first button;

The 'D' letter button, which is the first button, is displayed in a different color (eg, gray) to distinguish it from two or more buttons ('O, N' letter buttons) that are not the 'D' letter button.

Step A3: A step in which the touch of the first button is released.

For example, to explain

The first button, the 'D' letter button, is a step in which the touch is released (eg, the finger is separated from the touch screen). (not shown)

Stage A4: The stage in which the results of stage A2 are maintained or stage A2 is re-executed.

Simply put,

When step A3 proceeds, that is, when the touch is released,

Conventionally, as soon as the touch is released, the color of the 'D' letter button, which is the first button, is returned to white.

In the present technology, even when the touch is released, the color of the 'D' letter button, which is the first button, is maintained in gray.

To explain a little more,

When step A3 proceeds, that is, when the touch is released,

In the related art, as soon as the touch is released, the color of the 'D' letter button, which is the first button, is returned to the same color (eg, white) as other buttons, so it is difficult to recognize which button is the previously touched button.

(Although, in the prior art, as in Fig. 47, a pop-up (also called a 'preview') that informs the button (eg, 'D' letter button) in which the touch is maintained is also called. Example: 'D' letter button in Fig. 47 Even if there was an enlarged display of the 'D' character button with an area of about 4 times the area of the 'D' character button above), as soon as the touch is released, the popup disappears, so the popup is only shown for a very short time. , it is difficult for the user to see properly, and after a period of time, it is not known at all.)

However, in the present technology, the color of the 'D' letter button, which is the first button, is maintained in gray even when the touch is released.

To explain a little more,

that stage 2 is maintained or stage 2 is re-implemented, which is substantially the same;

Literally,

In the embodiment of step 2, 'a button that was displayed in a different color (eg, gray) to be distinguished from two or more other buttons ('D, N' letter buttons) before the 'D' letter button, which is the first button, was touched. The same color (e.g., white) so that the letter O' button is indistinguishable from one or more buttons (eg, 'N' letter button) that are neither the 'O' letter button that is the button nor the 'D' letter button that is the first button ) is indicated,

The 'D' letter button, the first button, is displayed in a different color (eg gray) to distinguish it from two or more buttons ('O,N' letter buttons) that are not the 'D' letter button. , the result of step A2 remains the same, or

In the embodiment of step 2, 'a button that was displayed in a different color (eg, gray) to be distinguished from two or more other buttons ('D, N' letter buttons) before the 'D' letter button, which is the first button, was touched. The same color (e.g., white) so that the letter O' button is indistinguishable from one or more buttons (eg, 'N' letter button) that are neither the 'O' letter button that is the button nor the 'D' letter button that is the first button ) is indicated,

The 'D' letter button, which is the first button, is displayed in a different color (eg gray) to distinguish it from two or more buttons ('O, N' letter buttons) that are not the 'D' letter button. will become

Step A5: A step in which the second button is touched.

For example, to explain

It is a step in which a touch to the 'N' character button, which is the second button, is initiated as shown in FIG.

Step A6: A step in which the first button is displayed indistinguishably from one or more buttons that are neither the first button nor the second button .

For example, to explain

46, the first button 'D' letter button,

This is a step in which the same color (eg, white) is displayed to be indistinguishable from one or more buttons that are neither the 'D' letter button, which is the first button, nor the 'N' letter button, which is the second button.

( FYI, after all,

The second button is displayed to be distinguished from two or more buttons other than the second button.

E.g,

The second button, 'N' letter button,

It is displayed in a different color (eg gray) to distinguish it from two or more buttons (eg, 'D, O' letter buttons) that are not the second button, 'N' letter button)

Now, I will explain two systems (steps B1 to B5 and C1 to C6) in the case of an input mode in which only single touch touch with one finger is used, and the touched button is displayed separately from other buttons only after the touch is released . .

Step B1: A step in which a touch on the first button is initiated.

Since the same description as in step A1 can be applied here as well, a description thereof will be omitted.

Step B2: A step in which the touch of the first button is released.

Since the same description as in step A3 can be applied here, a description thereof will be omitted.

Step B3: The first button to be touched A button that has been previously displayed to be distinguished from two or more other buttons is displayed indistinguishably from one or more buttons that are neither the button nor the first button, and the first button is two or more buttons that are not the first button Steps marked distinct from

Since the same description as in step A2 can be applied here as well, a description thereof will be omitted.

Step B4: A step in which the second button is touched.

Since the same description as in step A5 can be applied here as well, a description thereof will be omitted.

Step B5: A step in which the first button is displayed indistinguishably from one or more buttons that are neither the first button nor the second button .

Since the same description as in step A6 can be applied here as well, a description thereof will be omitted.

( For reference, after that, when the touch of the second button is released, eventually, the second button is displayed to be distinguished from two or more buttons other than the second button. )

C1 Step: A step in which a touch on the first button is initiated.

Since the same description as in step A1 can be applied here as well, a description thereof will be omitted.

C2 Step: A step in which the touch of the first button is released.

Since the same description as in step A3 can be applied here, a description thereof will be omitted.

Step C3 : Before the first button was touched , a button that was displayed to be distinguished from two or more other buttons is displayed indistinguishably from one or more buttons that are neither the button nor the first button, and the first button is A stage displayed distinctly from two or more buttons other than one button .

Since the same description as in step A2 can be applied here as well, a description thereof will be omitted.

C4 Step: A step in which a touch on the second button is initiated.

Since the same description as in step A5 can be applied here as well, a description thereof will be omitted.

C5 Step: A step in which the touch on the second button is released.

For example, to explain

This is a step in which the touch of the 'N' character button, which is the second button, is released. (not shown)

C6 Step: A step in which the first button is displayed indistinguishably from one or more buttons that are neither the first button nor the second button.

Since the same description as in step A6 can be applied here as well, a description thereof will be omitted.

( For reference, after all, the second button is displayed to be distinguished from two or more buttons other than the second button. )

Now, let's look at the case of the input mode in which multi-touch is used.

When multi-touch is performed in a state in which a plurality of buttons are being touched in an area having a plurality of buttons, there is a concept of a target button for which button is touched by the user as a real target among the plurality of touched buttons.

For example, in the keyboard as in Fig. 44

If, in multi-touch, the target button recognition method is a system in which the rule that the button including the lowest touch point among multi-touched touch points is recognized as the target button is applied.

The user tried to properly touch only the X letter button with the index finger so that the X letter button becomes the target button, and touch the middle and ring fingers anywhere above the index finger.

If multi-touch was made in which the index finger was touching the letter X button, the middle finger the letter F button, and the ring finger the letter Y button, the X letter button would be recognized as the target button properly. If the rule is that the rumor of the letter assigned to the ground target button is entered, a lowercase letter x will be entered instead of an uppercase letter X.)

If, in multi-touch, the target button recognition method is a system in which a button including the highest touch point among multi-touched touch points is recognized as a target button, the Y letter button will be recognized as a target button. , if multi-touch is made, if the rule is that the rumor of the character assigned to the target button is input, lowercase y will be input instead of uppercase Y.)

If, in multi-touch, the target button recognition method is a system in which the rule that the button including the first touched touch point among the multi-touched touch points is recognized as the target button is applied.

The user tried to touch the X letter button first so that the X letter button becomes the target button, and touch the middle and ring fingers at any time only later than the index finger.

The index finger was touched first, and then the X letter button was touched.

The middle finger was touched after the index finger, and it was touched by the letter F button,

If the ring finger was touched after the middle finger, and a multi-touch was made in which all three fingers were being touched while touching the Y letter button, the X letter button would be properly recognized as the target button. (If multi-touch is made, if the rule is that the rumor of the character assigned to the target button is input, a lowercase x will be input instead of an uppercase X.)

If, in multi-touch, the target button recognition method is a system in which a button including the last touched touch point among multi-touched touch points is recognized as the target button, the Y letter button will be recognized as the target button. (If multi-touch is made, if the rule is that the word of the character assigned to the target button is input, lowercase y will be input instead of uppercase Y.)

As above, when multi-touch is made , the first touch A button with a touch point is recognized as a target button, but

As the multi-touch progresses, that is, the As the number of touch points increases, the target button may be changed according to the multi-touch order relationship, the multi-touch location relationship, and the complex relationship between the multi-touch sequence and the multi-touch location locations. (Of course, there are cases where the target button does not change.)

For example, to explain

In the description of the target button recognition method in multi-touch using the X, F, Y letter buttons as an example, the first touched letter button is the X button, and the target button recognition method selects the highest touch point among the multi-touched touch points. In the system where the rule that the containing button is recognized as the target button is applied

If a multi-touch was made in which the index finger was touching the X letter button, the middle finger the F letter button, and the ring finger was touching the Y letter button,

The Y letter button will be recognized as the target button.

That is, the letter X button, which is the first touched letter button, was the first first target button, but as the multi-touch progresses, the letter Y button will be changed to the first target button.

However, in the description of the target button recognition method during multi-touch using the X, F, Y letter buttons as an example, the first-touched letter button is the X button, and the target button recognition method is the lowest touch among the multi-touched touch points. In a system where the rule that a button containing a dot is recognized as a target button is applied

If a multi-touch was made in which the index finger was touching the X letter button, the middle finger the F letter button, and the ring finger was touching the Y letter button,

The X letter button will be recognized as the target button.

That is, the letter X button, which is the first touched letter button, was the first first target button, and even after multi-touch is performed, the first target button will be maintained as the letter X button as it is.

And, it will be easier to understand if the concepts of the first and second target buttons used in the following implicit phrases are changed to the concepts of the first button and the second button in a system in which only a single touch exists.

First, not only single-touch touch with one finger, but also multi-touch The case of a system in which a button recognized as a target button is displayed to be distinguished from other buttons as soon as a certain touch is made in the input mode used will be described.

(And, The final target button recognition time for multi-touch is This is a case where the condition is the point at which even one touch point decreases. That is, if the number of multi-touch touch points starts to decrease, the target button cannot be changed even if it increases.)

D1 step : single touch Steps to be undertaken

Whether the user intends to single-touch or multi-touch, that is, even if multi-touch is attempted, not all fingers are touched at the same time.

And, it was said that even if the current condition is a system in which (a button recognized as a target button) is displayed separately from other buttons as soon as a certain touch is made, single touch is initiated.

For example, to explain

(As the 'O' character button was recognized as the target button just before as shown in Fig. 44, the 'O' character button is displayed in a different color (eg gray) to distinguish it from other buttons (eg, 'D, N' character button) It could have been.)

At this time, as shown in FIG. 45 , a single touch on the letter 'D' button (recognized as the first target button in step D2) is initiated.

D2 step : single touch Step in which the present button is recognized as the first target button

For example, to explain

This is a step in which the 'D' character button, which is a single-touched button, is recognized as the first target button.

Step D3: Before the first target button was touched , a button that was displayed to be distinguished from two or more other buttons is displayed indistinguishably from one or more buttons that are neither the button nor the first target button, and the first target button The step of being displayed to be distinguished from two or more buttons other than the first target button;

For example, to explain

As in Figure 45,

Before the 'D' character button, which is the first target button, was recognized as a target button, the button 'O' was displayed in a different color (eg gray) to distinguish it from two or more other buttons ('D, N' character buttons). The 'button is the same color (e.g., white) to be indistinguishable from one or more buttons (eg, 'N' character button) that are neither the 'O' button, which is the button, nor the 'D' letter button, which is the first target button. is displayed as

The 'D' letter button, which is the first target button, is displayed in a different color (eg, gray) to distinguish it from two or more buttons ('O, N' letter buttons) that are not the 'D' letter button.

D4 Step: If, the first D1 at the stage single touch with multi-touch As it progresses, multi-touch A step in which the first target button can be changed as it progresses

'As above, when multi-touch is made , the first touch A button with a touch point is recognized as a target button, but

As the multi-touch progresses, that is, the As the number of touch points increases, the target button may be changed according to the multi-touch order relationship, the multi-touch location relationship, and the complex relationship between the multi-touch sequence and the multi-touch location locations. (Of course, there are cases where the target button is not changed.)' Please refer to the phrase and its surroundings, especially the description below.

Step D5 :

if, D5 If the first target button is changed as the stage progresses,

before the change The first target button, before the change It's not even the first target button, after change Displayed indistinguishably from one or more buttons that are not even the first target button,

after change The first target button, after change Displayed to be distinguished from two or more buttons other than the first target button,

if, D5 As the stage progresses, if the first target button is not changed, D3 step is maintained D3 A phase in which the phase is re-executed.

For example, to explain

If the 'D' character button recognized as the first target button in step D2 goes through step D4, the first target button is changed to an 'O' character button,

One or more buttons (for example: It is displayed in the same color (eg white) indistinguishable from the 'N' letter button),

The 'O' character button, which is the first target button after the change, has a different color (eg, 'D, N' character button) to be distinguished from two or more buttons (eg, 'D, N' character buttons) that are not the 'O' character button, which is the first target button after the change Example: Steps indicated in gray).

If the 'D' character button recognized as the first target button in step D2 goes through step D4 and the first target button remains as the 'O' character button, the 'D' character button is grayed out. A step, that is, a step in which the result of step D3 is maintained or step D3 is re-executed.

D6 Step: A step in which even one touch is released.

Now, it is a step in which the user starts to release the touch to terminate the touch for recognizing the first target button as a multi-touch.

Until step D5 (if it is not a single touch, even more), after a single touch, the number of touch points can only increase, but cannot decrease, that is, until step D5, touch with the maximum number of touch points intended by the user. is a step in which

Here, step D6 is a step in which the user completes the multi-touch and starts to release the multi-touch, and is a step in which the touch points are initially decreased. Therefore, the phrase 'even one touch' is in the connotation.

D7 Step: A step in which the final first target button is determined

In the description of step D6, step D5 is a step in which the maximum number of touches intended by the user is made, so step D7 after step D6 is a step in which the final first target button can be determined.

For example, in this embodiment, it is assumed that the letter button 'D' is determined as the final first target button.

For further explanation, for example,

If, in multi-touch, the target button recognition method is a system in which the rule that the button including the last touched touch point among the multi-touched touch points is recognized as the target button is applied.

While the user tries to touch the Y letter button last so that the Y letter button becomes the target button, and tries to touch the index and middle fingers at any time before the index finger

The index finger was touched first, and then the X letter button was touched.

If the middle finger is touched after the index finger, and multi-touch is in progress until the letter F button is touched,

The current first target button is an F letter button.

However, if the ring finger was touched after the stop, and a multi-touch was made in which all three fingers were being touched while touching the Y letter button, the Y letter button would be recognized as the target button. In this case, the Y letter button is recognized as the final first target button, so that the first target button can be changed.

D8 Stage: stage where all touches are released.

Now, in order to completely terminate the touch for the user to recognize the first target button as a multi-touch, all touches are released. That is, there is no single touch point where the display screen is touched.

D9 step : single touch steps to be undertaken.

Now, it is a step of starting a new single-touch or multi-touch for the user to recognize the second target button as a multi-touch.

Whether the user intends to single-touch or multi-touch, that is, even if multi-touch is attempted, not all fingers are touched at the same time.

And, it was said that even if the current condition is a system in which (a button recognized as a target button) is displayed separately from other buttons as soon as a certain touch is made, single touch is initiated.

For example, to explain

As shown in FIG. 45, a single touch to the 'N' character button, which is the first button, is initiated.

D10 Step: a step in which the final first target button is displayed indistinguishably from one or more buttons that are neither the final first target button nor the second target button.

For example, to explain

One or more buttons (e.g., 'O' letter button) where the 'D' letter button, which is the final first target button, is not a 'D' letter button, which is the final first target button, and is not a 'N' letter button, which is the second target button ) are displayed in the same color (eg, white) indistinguishable from them.

(For reference, the second target button (=single-touched button) up to now is displayed in a design different from that of two or more buttons other than the second target button.

For example, to explain

The 'N' character button, which is the second target button (=single-touched button) so far, is not the 'N' character button, which is the second target button, but two or more buttons (eg, 'D, O' character button) It is displayed in a different color (eg gray) to distinguish it from

Now, not only single-touch touch with one finger but also multi-touch The case of a system in which a button recognized as a target button is displayed in an input mode to be used to be distinguished from other buttons will be described.

(And, The condition that the (final) target button recognition point for multi-touch is the point at which all multi-touched touch points are released is also added. That is, even if the number of multi-touch touch points starts to decrease, if the number of multi-touch touch points increases, there is a condition in which the target button may be changed. Also, a condition is added that the point at which the display of the first target button to be distinguished from other buttons is released is the point in time when the user starts a new single touch or multi-touch for recognizing the second target button as a multi-touch).

E1 step : single touch or multi-touch Steps initiated and made.

For example, to explain

(As the 'O' character button was recognized as the target button just before as shown in Fig. 44, the 'O' character button is displayed in a different color (eg gray) to distinguish it from other buttons (eg, 'D, N' character button) It could have been.)

At this time, as shown in FIG. 45 , a single touch may have been made on the 'D' character button (recognized as the first target button in step E3), and a multi-touch is initiated so that the 'D' character button is recognized as the target button, and the user This is the stage where the intended touch is made.

E2 Stage: stage where all touches are released.

This is a step of releasing all touches in order to completely terminate the touch for the user to recognize the first target button as a multi-touch. That is, there is no single touch point where the display screen is touched.

E3 Step: A step in which the first target button is recognized.

For example, to explain

This is a step in which the 'D' letter button is recognized as the first target button.

E4 Step: The first target button to be touched Buttons that have been previously displayed to be distinguished from two or more other buttons are displayed indistinguishably from one or more buttons that are neither the button nor the first target button, and the first target button is two buttons that are not the first target button A step displayed to be distinguished from the above buttons.

For example, to explain

As in Figure 45,

Before the 'D' character button, which is the first target button, was recognized as a target button, the button 'O' was displayed in a different color (eg gray) to distinguish it from two or more other buttons ('D, N' character buttons). The 'button is the same color (e.g., white) to be indistinguishable from one or more buttons (eg, 'N' character button) that are neither the 'O' button, which is the button, nor the 'D' letter button, which is the first target button. is displayed as

The 'D' letter button, which is the first target button, is displayed in a different color (eg, gray) to be distinguished from two or more buttons ('O, N' letter buttons) that are not the 'D' letter button.

E5 step : single touch steps to be undertaken.

Now, it is a step of starting a new single-touch or multi-touch for the user to recognize the second target button as a multi-touch.

Whether the user intends to single-touch or multi-touch, that is, even if multi-touch is attempted, not all fingers are touched at the same time.

And, although the current condition is a system in which (a button recognized as a target button) is displayed separately from other buttons only after all touches are released, the point at which the display of the first target button to be distinguished from other buttons is released 2 It is said that the single touch is initiated because it is the point at which the user starts a new single touch or multi-touch for recognizing the target button as a multi-touch.

For example, to explain

As shown in FIG. 45 , a single touch to the 'N' character button, which is the first button, is initiated.

E6 Step: The first target button is not the first target button, E5 in step single touch A step that is displayed indistinguishably from one or more buttons that are not buttons.

For example, to explain

One or more buttons (eg, 'O' letter button) that the 'D' letter button, which is the first target button, is not a 'D' letter button, which is the first target button, and is not a single-touched 'N' letter button in step E5. It is a stage that is displayed in the same color (eg, white) to be indistinguishable from others.

(For reference, the second target button has not yet been determined, and as a result, three or more buttons ('D, N, O' letter buttons) may be displayed with the same color (eg, white) indistinguishable from each other. am.)

Now, not only single-touch touch with one finger but also multi-touch The case of a system in which a button recognized as a target button is displayed in an input mode to be used to be distinguished from other buttons will be described.

(And, The condition that the (final) target button recognition timing for multi-touch is the point at which all multi-touched touch points are released is also added. That is, even if the number of multi-touch touch points starts to decrease, if the number of multi-touch touch points increases, there is a condition in which the target button may be changed. In addition, a condition is also added that the point at which the display of the first target button to be distinguished from other buttons is released is the point in time when all new single-touch or multi-touch touch points for recognizing the second target button are released.)

Step F1: single touch or multi-touch Steps initiated and made

Since the same description as in step E1 can be applied here as well, a description thereof will be omitted.

Step F2: All touches are released

Since the same description as in step E2 can be applied here as well, a description thereof will be omitted.

Step F3: A step in which the first target button is recognized

Since the same description as in step E3 can be applied here as well, a description thereof will be omitted.

Step F4: Before the first target button is touched, a button that has been displayed to be distinguished from two or more other buttons is displayed indistinguishably from one or more buttons that are neither the button nor the first target button, and the first target button The step of being displayed to be distinguished from two or more buttons other than the first target button;

Since the same description as in step E4 can be applied here as well, a description thereof will be omitted.

Step F5: single touch or multi-touch Steps initiated and made.

This is a step in which a single touch or multi-touch is newly performed for the user to recognize the second target button as a multi-touch.

For example, to explain

As shown in FIG. 46, multi-touch is initiated so that the 'N' character button is single-touched or the 'N' character button is recognized as a target button, so that the user's intended touch is made.

Step F6: All touches are released.

For example, to explain

This is a step of releasing all touches in order to completely terminate the touch for the user to recognize the second target button 'N' as a multi-touch. That is, there is no single touch point where the display screen is touched.

Step F7: A step in which the first target button is displayed indistinguishably from one or more buttons that are neither the first target button nor the second target button.

For example, to explain

One or more buttons (eg, 'O' letter button) in which the 'D' letter button, which is the first target button, is neither the 'D' letter button, which is the first target button, nor the 'N' letter button, which is the second target button It is a step that is displayed in the same color (eg, white) to be indistinguishable from

( For reference, the second target button is displayed to be distinguishable from two or more buttons other than the second button.

For example, to explain

The 'N' character button, which is the second target button, has a different color (eg gray) so that it can be distinguished from two or more buttons ('D, O' character button) that are not the 'N' character button, which is the second button. displayed.)

The method of displaying the button operated immediately before described so far to be distinguished from other buttons can be applied regardless of any language in the world other than the mentioned language. For example, it is applicable to Greek/Roman script, Cyrillic script, Arabic script, Southeast Asian script, Indian script, Thai script mode, Vietnamese script mode, and detailed languages English, French, German, Spanish, etc.

And, although the method of the present application has been described as an example that only the text button is a button operated immediately before, it can be applied to a function button other than a text button.

Examples of function buttons include a text mode switch button, an environment setting button, a voice input mode button, and a delete button.
