Description

{THE SIMPLE METHOD OF CORRECTION OF THE TYPOGRAGHICAL ERROR WHILE TEXT INPUT AT ELECTRONIC DEVICE}

A simple method of correcting a typo when entering text on an electronic device and displaying the manipulated buttons.

Conventionally, when a character that was not originally targeted due to a typo is entered, the character is deleted, and then the character that was originally targeted is input. Therefore, in the case of the QWERTY keyboard, it is mostly necessary to input 2 characters (1 delete button, 1 character button which was originally targeted) to input a new character which was originally targeted due to an error.

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

In small keyboards including 3X4 keyboards, the fastest text input speed may be Korean.

Hangul input method using 3X4 keyboard has various methods including Cheonjiin method, Naragle method, and Sky method.

Of course, Hangul can also be entered faster if you enter it through the QWERTY keyboard.

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

Hangul input, so you can type fairly quickly via the 3X4 keypad, to what you want to avoid typos biggest reason, do not use the QWERTY keyboard to more quickly enter, various Hangul input with 3 X4 keyboard mentioned above Koreans to enter the open letter made through methods contrary there is a 70% in the smartphone era,

Of basil number 26 characters (of note, Hangul basil 40 characters) even if only for not only English, 3 X4 keyboard in is extremely difficult to even character input from former feature phone era, almost the majority of foreigners When entering your own language (typical typos that occur frequently when using Qwerty keyboards like Koreans, which are virtually inevitable with 3X4 keyboards), you can enter them through QWERTY , being careful not to make typos. There is nothing else.

Under these circumstances, if the typo can be corrected easily, the use rate of Qwerty keyboards of Koreans will increase rapidly, and the convenience of using QWERTY keyboards of foreigners will be greatly improved.

In addition, through the technology of the present application to be introduced further in the future, since a typo correction in a small keyboard assigned a number of characters to a single button including a 3X4 keyboard, it is also very easy to use the 3X4 keyboard.

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

When typing letters on small mobile devices including mobile phones, a lot of typos occurs.

For example, most of the conventional feature phones have a small physical button including a 3X4 keyboard instead of a QWERTY keyboard. Even though a physical button is provided, many characters are assigned to one button. Most of the time, the target character button was touched, but a lot of typos occurred due to the subsequent operation mistake (the reason will be explained in 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, and many typos occur.

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

As a conventional method for preventing conventional typos,

The method applied to the Samsung Galaxy S of Korea, and also to prevent typos applied to the smartphones of almost all smartphone companies around the world, including Apple, LG Electronics,

For example, as shown in FIG. 2, if a finger is touched on the letter button, while the letter button is displayed differently from other buttons, the letter button is placed on the letter button. A pop-up ('POP UP' in Figure 2, also known as the preview function) is generated several times larger than 'D', and a finger is released from the 'D' character button and 'D' is finally entered. .

(And at the same time you release your finger from the 'D' button, as in Figure 1, the 'D' button is displayed the same color as the other buttons, and the popup on the 'D' button disappears.)

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

Because we say that a typo occurs frequently, but in most cases we are typing the target character correctly, that is, it does not occur very often, so the user touches the target character button precisely. I think I did it, and because I don't properly check the characters displayed in the popup, I take my finger off.

If you want to enter the characters correctly by the conventional method mentioned above,

Check the pop-up to see what character button you touched.

If you have touched the target letter button correctly, lift your finger to enter the target letter.

If it is determined that the wrong character button is touched instead of the target character button, the user should input the target character by dragging his finger to the target character button without lifting his or her finger.

However, since the user has to pay much attention to check the characters displayed in the popup every time the user inputs each character, the user is quite tired and the character input speed is significantly reduced. Since the typo does not occur excessively, the user thinks that even if the wrong button is touched, the user has correctly touched the target character button. Typing characters off the keyboard causes typos.

After all, even if you have a tool called pop-ups, you will often have typos.

That is, in a small electronic device including a smart phone Touch Qwerty keyboard  For various reasons, including the reasons described above, Tablet PC Qwerty keyboard  or Desktop PC Qwerty keyboard  It is very difficult to avoid typos, which occur more often. In this situation, it is difficult to avoid typos anyway, so if a method for simplifying typos is developed, the effect on convenience is very effective. Number  There is nothing else.

In addition, there are many methods for inputting characters with a keyboard composed of buttons assigned with a plurality of characters per character button including a 3X4 keyboard, not a button assigned with one character per character button including a qwerty keyboard. Although the size of the character buttons in keyboards in which such a method is applied is larger than the buttons of the QWERTY keyboard, a number of characters are assigned to each character button, subsequent problems, and inherent disadvantages of the developed methods. For a variety of reasons, including typos, many typos have occurred, and are still typing characters originally intended after deleting the input characters due to typos. In any case, you need at least two strokes to correct a typo.

The present application in this text button per plurality of characters is input due to a typo, even when entering characters with the assigned button text, eliminating the step of a user is deleted, thereby generating a no signal, as a substantially single action of the For example, a target character may be input from the original target by directly replacing the input character due to a typo with a new target character. Thus, in most cases, only one stroke is needed.

The matters described as the background art are only for the purpose of improving the understanding of the background of the present invention, and all of the matters described as the background art correspond to the conventional arts already known to those skilled in the art. It should not be accepted as acknowledgment.

1.The characters entered due to typos,

Without deleting, Substantially in a single act, the wish to be simply replaced by a new character (who aim to enter the characters from the original due to a typo).

In the present application, the user deletes a character inputted due to a typo, and generates a signal (e.g., a left arrow (or right arrow) for implementing the present method of FIG. 3 (or FIG. 4)) is displayed. Press the control button ('LEFT BUTTON' or 'RIGHT BUTTON' in Figs. 3 and 4) or control buttons for character modification (Fig. 23) marked with characters for the implementation of the method of Fig. 23 (or Fig. 24 or Fig. 40). , By pressing 'LEFT BUTTON' or 'RIGHT BUTTON' in Fig. 24 and 40), the character entered due to a typo is displayed on the character button immediately to the left (or right) of the character button assigned to the character button. You can enter the character that was originally targeted by replacing it with the character that was assigned, that is, the character that was originally assigned to the button that was originally targeted . Therefore, in the case of the QWERTY keyboard to which the present method is applied, most of the cases in which only one stroke is required to input a character input due to a typo as a new character originally intended for it will be used.

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

That is, in the case of a QWERTY keyboard, a character input due to typos is replaced with a new character originally intended. In the conventional method, two strokes were required.

It's hard to say that the effect is great on the keyboard of the desktop where typos are not frequent, but it is very effective on small mobile devices including smartphones where typos are common.

[In fact, if the present technology is applied to a smart phone, in the conventional smart phone drawings as shown in 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 positioned immediately to the left of the button to which the character entered immediately before is assigned (the white background 'S' character) Button) and a control button ('LEFT BUTTON' or 'RIGHT BUTTON' shown in FIG. 23) that displays a letter ('S' or 'F') assigned to the letter button (white background 'F' letter button) located in the right direction. = 'S' or 'F' control button on gray background is placed in place of the conventional shift button and delete button, or

As shown in Figure 40, the position of the shift button and the delete button is the same as the conventional one, and as a control button for applying the present technology, a character button located immediately to the left of the button assigned with the character input immediately before (white background 'S' character) Button) and the control button ('LEFT BUTTON' or 'RIGHT BUTTON' in Fig. 40) that displays the letter assigned to the letter button (white background 'F' character button) located in the right direction. 'F' control button) is located next to the conventional space button seat

But it will be explained based on Fig. 24 for the purpose of enhancing the unity and understanding with the following description of various embodiments.

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

The following briefly describes the conventional technology applied to the Samsung Galaxy S described in the section 'Technology behind the invention'.

If a letter button (for example, '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 popup is formed directly above the button.

When a touch on a letter button is released, the popup disappears, and the color of the letter button touched before is returned to the same color as other buttons.

However, when applying the technology of the present application, when the display of the touched button starts to be implemented slightly differently as follows, when the technology of the present application is further progressed later, the user clearly knows which character button was the button touched immediately before. The user will be more convenient. (However, even if it starts to be implemented as before, the technology of the present application is not impeded.)

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

If a character button is touched, the color of the character button changes color differently from other buttons, and a popup is formed directly above the button.

When the touch of a character button is released, the disappearance of the pop-up disappears. However, the color of the character button that has been touched immediately before is maintained in a different color from that of the other buttons. When a new button is touched, It is recommended that the colors be the same as those of the other. .

(But in fact, it would have been better if it had already been implemented in the previously recommended method. In the prior art, since the popup formed near the touched character button disappears at the same time as the finger is released from the character button, And in actual use, since the touch time is very short, it is difficult to accurately recognize the characters in the popup.)

The following process also proceeds under the assumption that the state display (eg, color processing) method of the touched button is applied to the present technology.

As shown in Figure 24, in the process for entering the 'SO GOOD' in the character input window in 'AREA-D' of Figure 24,

At the time of entering 'SO GOO' correctly (not shown), I tried to input the last letter 'D', but after the wrong 'S' letter button was touched, my finger was released. S is entered in the character input window at -D ', and the cursor is positioned immediately after the' S 'input by a typo, such as' AREA-D' in FIG.

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

In this situation,

Conventionally, due to typos, S ' The user deletes it by pressing the delete button, D ' , But

In this application, due to a typo, S ' Without deleting the user, S ' ' D ' Can be changed to

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

Of the button assigned to the immediately preceding character ('S') (that is, the letter button 'S')

'A' assigned to the character button ('A' character button) immediately to the left is assigned to a control button called 'LEFT BUTTON' in FIG. 25,

'D' assigned to the character button ('D' character button) on the right side is assigned to a control button called 'RIGHT BUTTON' in FIG. 25,

Among the control buttons labeled 'A' and 'D', the control button 'D' is displayed ('RIGHT BUTTON' in FIG. 25) is touched, and the input 'B' is input due to a typo in FIG. 25 AREA-D. S 'can be replaced with' D 'immediately, as shown in Figure 26 (in the end, it was entered as' SO GOOD').

That is, it is not a concept of inputting 'D' after the user deletes 'S' as conventionally.

(In the description of the embodiment of the present application, the touched button may be kept different from the other buttons even after the touch is released. However, the color of the touched button is different from the other buttons as soon as the touch is released. This same reversal can also implement the techniques of the present application, so that conventional desktops , which generally cannot change button colors, can be implemented. The physical keyboard of PC will also be able to apply the correcting method of typos, though the effect is not great .

While reviewing the above embodiments again, let's look at the meaning of the implied phrases claimed herein.

As shown in Figure 24, in the process for entering the 'SO GOOD' in the character input window in 'AREA-D' of Figure 24,

At the time of entering 'SO GOO' correctly (not shown), I tried to input the last letter 'D', but after the wrong 'S' letter button was touched, my finger was released. 'S' was entered due to a typo in the character input window at '-D' (in the end, 'SO GOOS' was entered), and as in FIG. 25, the 'S' entered as a typo like 'AREA-D'. Suppose the cursor is located behind it.

When the state is as described above, the first step proceeds.

" First step: the step of grasping the character of the position derived by the position definition (1) of a specific relationship with the cursor position or state in the character input window ".

(In the first step,

It is recommended that the position derived by the position definition (1) of 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, 'the 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 determined in advance that the position (1) determines how much the position is moved back and forth from the cursor, including immediately after the current cursor position as well as immediately after or immediately before or after the current position. )

Then, in the end, the 'character of the position derived by the positional rule (1) of the specific relationship with the cursor position and state' means a character to be changed in the future, and in this embodiment, the character immediately before the cursor, which is input due to a typo. Phosphorus, ' S' .

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

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

In general, since the cursor state in a portable electronic device including a smartphone is the INSERT mode in the desktop PC, the cursor position is the position just before the cursor in this embodiment, but in the NOT INSERT mode in the desktop PC, the current cursor position itself is changed. It would be most desirable to make the cursor position and state and the position derived by a particular relationship rule (1).

(However, the rule (1) is determined in advance, including that it can be defined as how far back and forth from the cursor, including immediately before, immediately after, or immediately after and immediately after the cursor even in the NOT INSERT mode. .)

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

In this situation,

Conventionally, a user deletes an input 'S' due to a typo by pressing a delete button, and inputs 'D', which was originally intended to be input.

In the present disclosure, the user may change 'S' to 'D' without deleting the 'S' input due to a typo. This will be explained in detail.

The second step: the position of the character button on the keyboard to which the character identified in the first step is assigned and the one or more characters assigned to the character button of one or more positions derived by the position rule 2 of a specific relationship are identified. Steps

(In the second step,

The derived character button of one or more positions derived by the position definition (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 assigned the character identified in the first step. It is recommended to use the character button located just to the left of the character button on the keyboard or to the right of the character button.

In view of the embodiment cited in Fig. 30

In the second step,

The derived character button of one or more positions derived by the position definition (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 assigned the character identified in the first step. It is recommended to use the character button located directly above or below the character button on the keyboard. )

To describe the above two-stage phrase, for example with Figs. 25 and 26,

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

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

Naturally, it will be the letter 'S' button on the keyboard in 'AREA-E' of FIG.

'Character buttons of one or more positions derived by the position rule (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'

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

(However, 'the character button of one or more positions derived by the position rule (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'

As in this embodiment, not only the character button immediately to the left or right of the character button ('S' character button) on the keyboard to which the character identified in step 1 is assigned, but also immediately left or right right, immediately left or right right In the first step, including any one or more of immediately right, immediately left of the left or immediately right of the right, immediately above, immediately below, immediately above left, immediately below left, immediately above right, or just below right The rule (2) on which direction the character button is located in which direction and how far from the character button on the assigned keyboard is determined in advance.)

Then, eventually, the character identified in the first step is assigned to one or more characters assigned to the character button at one or more positions derived by the position specification (2) of the specific relationship with the position of the character button on the assigned keyboard 'Is the character to be changed to the candidate character (s) to be changed in the future, and in this embodiment, the character' S 'assigned to the immediately preceding character (cursor) ('A' character button or 'D' character button) derived by the position specification (2) of the position and specific relationship (for example, to the immediate left or right of the 'S' character button) (' A' or ' D' ) .

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

' Step 3: The step of assigning one or more characters (any one or more characters) identified in the second step to one or more control buttons '

(In the third step,

All of the one or more characters identified in the second step is assigned to one or more control buttons. Assigned  It is recommended.

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 be displayed.

In the third step,

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

In the third step, the word 'control button' first appears, and the 'control button' may be referred to as a button that functions to change an already input character into another character.

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

That is, the character assigned to the control button (s) will continue to change as the cursor position and input continues.

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

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

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

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

The assigned letter 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 means that only the character including the arrow indicating the direction may be displayed instead of the assigned character, and the state of the button display may be blank.

In the second step, the 'specific relationship position rule (2)' is expected to be relatively simple, as in the present embodiment, in most cases where the technology of the present application is applied by someone in the future, so that even if the display behavior of the control button is blank, No problem is expected. This is because even if the control button in FIG. 25 is not labeled as 'A' or 'D'

If the provisions for Stage 2 and Stage 3

(Cursor) of the button ('S' character button) assigned to the character ('S') entered immediately before

The letter ('A') assigned to the letter button ('A' letter button) on the left is assigned to the control button 'LEFT BUTTON'.

If the character ('D') assigned to the character button ('D' character button) on the right is assigned to the control button 'RIGHT BUTTON',

'AFT' is assigned to the control button 'LEFT BUTTON'

It is easy to see that the control button 'RIGHT BUTTON' will be assigned 'D' (an embodiment of the behavior indicated by the arrow will be shown later).

Step 4: One of the one or more control buttons is selected, and a character assigned to the selected control button (or displayed after the assignment) is grasped

In the present embodiment, the control button (s) labeled 'LEFT BUTTON' or 'RIGHT BUTTON' assigned with 'A' or 'D' If the user touches the control button ('RIGHT BUTTON' in FIG. 25) displaying 'D', the character assigned to the selected control button will be recognized as 'D'.

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

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

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

That is, it is not a concept of inputting 'D' after the user deletes 'S' as conventionally.

In the fifth step,

The process of changing the text identified in step 1 to the text found in step 4

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 inputted after the character identified in the first step is deleted.

To describe the above phrase through this embodiment,

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

In electronic technology concept,

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

You can also implement 'S' to be replaced by 'D' directly,

Or, almost instantly, 'S' is deleted (automatically), 'D' is entered, and the user's eyes are implemented to look like 'S' is replaced by 'D' without the process of deleting 'S'. It may be.

Let's look at another embodiment to better understand the technology of the present disclosure, including making it clear that the characters assigned to the control buttons can vary.

In the process for entering 'SO GOOD' in the text input window as shown in Figure 24,

When 'SO GOO' was correctly entered (not shown), I tried to enter the last letter 'D', but after the wrong 'F' letter button was touched, my finger was released. It is assumed that 'F' is input to the character input window at '-D', and the cursor is positioned immediately after 'F' input by a typo, as in 'AREA-D' of FIG. 27.

 And, assume that the color of the 'F' character button is displayed differently from other buttons as shown in FIG. 27. (After all, 'SO GOOF' has been input.) (As mentioned above, FIG. 41 is controlled rather than FIG. 27. It seems to be a better arrangement for button placement.)

In this situation, conventionally, the user deletes the inputted ' F' due to the typos and inputs the ' D' that was originally intended to be input. However, in this embodiment, the user does not delete the ' F' ' F' can be changed to ' D' .

For example, referring to FIGS. 26 and 27, the character button (ie, 'F' character button) assigned with the character 'F' immediately inputted at the bottom of the display screen of FIG. 27 is assigned. 'D' is displayed among the control buttons with the letter 'D' and 'G' assigned to the letter button ('D' letter button) on the left and the letter button ('G' letter button) on the right. By touching the control button ('LEFT BUTTON' of FIG. 27), 'F' inputted by a typo of FIG. 27 AREA-D can be replaced with 'D' as shown in FIG. 26. GOOD '.)

<Delete: Delete as duplicate except alphabet>

That's like conventional F ' After deleting D ' It is not a concept of typing.

In the above method of the present application is a character entered due to a typo (eg ' F ' ) Originally targeted to a character (e.g. " D ' It's a technology that replaces with), but that's the idea of the user,

In electronic technology concept,

Figure 27 Display screen  At the bottom D ' Control buttons marked with Figure 27  ' LEFT BUTTON ' ),

' F ' Going ' D ' Can be implemented directly as

Or are almost instantly the 'F' (automatically) deleted, 'D' is entered, be implemented appear to the user's eye, without the process of 'F' is deleted, 'F' is to be immediately replaced with 'D' It may be.

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

Of course, the technique of the present application can be applied while moving the position of the cursor.

For example, a character entered immediately before a shifted cursor position may be replaced by a new character including an originally targeted character, including a character input due to a typo, without a user deleting a character.

<Deletion: Not required>

(For reference, in the above embodiments, when the cursor is displayed, L ' Lower case ' l ' I did not show it because it seemed to be confused with.

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

In the first step, if the position derived by the position definition (1) of a specific relationship with the cursor position or state in the character input window is 'position immediately before the cursor',

The character identified in the 'first step: the step of identifying the character of the position derived by the position definition (1) of a specific relationship with the cursor position or state in the character input window' is

Become 'S',

D 'assigned to the character button (=' D button ') located in the right direction of the' A 'and' S character buttons' allocated to the character buttons (= 'A button' 'Is displayed on the control button. In this state,' S 'can be directly replaced with' A 'by touching the control button (' LEFT BUTTON 'in FIG. 43) &Quot; AO GOOD &quot; (not shown).

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

<Deletion: The plot is virtually redundant>:

In short, the contents of the above paragraphs

Characters entered immediately by the user, "substantially", replace characters already entered, including characters entered due to typos, with new characters, including those originally intended, without the step of deleting them. I can say that.

The word "substantially" above

As explained in the paragraphs above

A character entered due to a typo (e.g. " F ' ) Originally targeted to a character (e.g. " D ' ), Literally, you can replace it right away,

A character entered due to a typo (e.g. " F ' ), The user can delete the original target character (e.g., &quot; D ' Just by touching the control button assigned)

A character entered due to a typo (e.g. " F ' ) Is deleted momentarily and then the originally targeted character (eg ' D ' ) Is entered,

A character entered due to a typo (e.g. " F ' ) Originally targeted to a character (e.g. " D ' Includes meanings that can be replaced with).

As in the above embodiment, in a virtual keyboard that appears when a character is input by standing a conventional smartphone vertically, since the horizontal length of each letter button is less than the vertical length, it is an elongated rectangular shape in the vertical direction, in most cases A typo is often caused by incorrectly touching a character button located to the left or right of the button originally targeted.

So, when applying the present technology to the virtual keyboard as shown in Figure 1 when the smartphone is put up vertically when entering the character, the original character, including the character entered due to the typo originally aimed at As a control button for changing to a new character including a character, a character button located immediately to the left of the button to which a character entered immediately before (cursor) is assigned and a character assigned to the character button located to the right of the right as shown in FIG. The control buttons displayed will suffice.

However, when the horizontal length of each character button is larger than the vertical length as shown in FIG. 9 (correct), that is, in most cases, a typo occurs because the character buttons are elongated to the left and right. In many cases, it is caused by incorrectly touching the character button located in the upper or lower direction.

When the technique of the present application is applied to a keyboard in which the width of each character button including Fig. 9 (correct) is larger than the height, characters originally targeted for characters already input, including characters input due to a typo, are originally intended. For example, to explain the control buttons needed to change to a new character, including

As shown in Fig. 30, the character button (for example, 'S' character button) to which the character (for example, 'S') entered immediately before (cursor) is assigned.

Character button (for example, 'L' character button)

On the character button (for example, the letter button "Y")

A control button that displays the assigned letters ('L' and 'Y') will suffice.

(The control button assigned 'L' assigned to the letter button (for example, 'L' letter button located in the upper direction) is 'UP BUTTON' in FIG. 30,

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

If the character button (eg 'F' character button) to which the character (eg 'F') input immediately before is assigned in FIG.

Character buttons (for example, 'D' character buttons)

The letter button to the right (for example, the letter G)

Character button (for example, 'R' character button)

Directly below the letter button (for example, the letter button "C")

If a control button displaying the assigned letters 'D', 'G', 'R', and 'C' is required, a control button may be provided as shown in FIG.

The control button in Fig. 32 displays the control button functions shown in Fig. 31 on one control button. After being displayed at once, the device can accept the expression of the user's direction by touching the area of the desired direction.

If it is desired to display only one character button at a time immediately after the character input immediately before the cursor (cursor) and two control buttons at which the character assigned to the character button located in the right direction is displayed, in a single button , The control button level at the bottom of the display screen of Fig. 36 can be used. (In fact, the control button in Fig. 36 is used for a slightly different purpose than the control button described above in the description of the embodiment using Fig. 36.)

Fig. 32 or Fig. 33 shows an example in which the characters assigned to the character buttons of the upper, lower, left, right, upper, lower left, upper right, or right lower right of the character button to which the character input immediately before (cursor) As shown in FIG.

'realistically, One time  By generating a signal,

The character entered immediately before is replaced by a character having a specific relationship with the character.

'Character of a specific relationship'

'The character entered immediately before and the character entered in the same button as the button (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 shown in FIG. 34, 37, or 39, when a typo occurs, as described above, the user does not delete the already input characters including the characters input due to the typo. ,

(Actually, by generating one signal,)

I'll explain how to replace it with the letter you originally targeted.

When a plurality of characters are assigned to the same button as shown in FIG. 34, 37, 38, or 39,

Since the size of the character button is quite large, it is very rare to operate the wrong character button rather than the intended character button.

I originally touched the letter button,

In many cases, a wrong button operation is used to mistype a character originally intended.

The reason for this is briefly mentioned in the section entitled 'Background of the invention', and will not be repeated here.

It will only explain how to replace previously entered characters, including characters entered due to typos, with characters originally intended without the user deleting them.

First, let me explain by example.

In the display screen as shown in FIG. 37, 38, or 39, during the final process of inputting 'SO POOR' into the character input window of 'AREA-D',

Even though 'SO POO' was correctly entered (not shown), I tried to input the last character 'R'. If the assigned 'Q' is entered (after all, 'SO POOQ' is entered), you can correct the typo in several ways as follows.

1. As the control button at the bottom of the display screen as shown in Fig. 39, the characters assigned to the 'PQRS' character button assigned to the character button 'Q' assigned immediately before (cursor) are 'P, Q, R, In the state that there are control buttons assigned 'P, R, S' except for 'Q' which is the character entered just before (cursor) among S '

Pressing a control button with 'R' assigned (e.g.) can cause 'Q' to be replaced by 'R' directly.

(If the above proceeds, now, the control buttons

'R', the character entered immediately before (Cursor) among the characters 'P, Q, R, S' assigned to the character button 'PQRS' The letters 'P, Q, S' except for will be assigned (e.g. marked), and in that state

If you press a control button with 'Q' assigned (e.g. marked), 'R' can be replaced by 'Q' directly.)

2. As the control button at the bottom of the display screen as shown in Fig. 38, all characters assigned to the 'PQRS' character button, which is the character button assigned to the character 'Q' which is input immediately before (cursor), are 'P, Q, When there are control buttons with R, S 'assigned (e.g. marked)

Pressing a control button with 'R' assigned (e.g.) can cause 'Q' to be replaced by 'R' directly.

(If so, now, the control buttons

(Cursor) Control buttons assigned to (P), P, Q, R, S, all of the characters assigned to the 'PQRS' character button assigned to the letter 'R' assigned to the previous character With

Pressing a control button with 'Q' assigned (e.g. marked) can cause 'R' to be replaced by 'Q' directly.)

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

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

With the control button on the right (= before) the assigned letter 'R' assigned (e.g.),

Pressing the control button labeled 'R' may cause the 'Q' to be replaced by 'R' directly.

(If the above proceeds, now, the control buttons

(Cursor) 'P', 'P', 'P', 'P', 'P', 'Q'

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

The letter 'S' assigned immediately to the right (= before) will be assigned (e.g. indicated), and in that state,

If you press the control button where 'Q' is assigned (eg, displayed), 'R' may be immediately replaced with 'Q'.

The third embodiment

In the third step,

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

Note that,

37, 38, and 39, the above-described embodiments 1, 2, and 3 are provided with a character button having only two letters assigned to the same button as in the keyboard of FIG. 34 or 36. The same applies to the keyboard.

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

If you wanted to enter 'D' as the last character, and you entered the wrong 'F' assigned to the same letter button as 'D' (after all, 'SO GOOF' was entered), There are several ways to correct typos (the following method is best recommended):

1. As a control button at the bottom of the display screen as shown in FIG. 36, of the letters 'D' and 'D' assigned to the 'DF' character button assigned to the character button 'F', which is input immediately before (Cursor) ( In the state where the control button ('1 BUTTON' in Fig. 36) is assigned (e.g., displayed) except 'F', which is the character entered immediately before

Pressing a control button with 'D' assigned (e.g.) can cause 'F' to be replaced by 'D' directly.

(If the above progresses, now, the control button

Characters other than 'D', the character entered immediately before (Cursor), among the characters 'D, F' assigned to 'DF' character button 'F' will be assigned (eg marked),

If you press the control button ('1 BUTTON' in Figure 36) that 'F' is assigned (e.g., it is possible to have 'D' replaced by 'F' immediately).

(Because 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 character other than the character entered immediately before.)

<Deletion: Not Needed>

In particular, in this case Like Figure 36  It's okay to have only one control button.

Why Examples  Through the following description.

Figure 36  When entering characters using the same keyboard,

' G ' I tried to type in. Due to a typo, H ' Is entered or

' H ' I tried to type in. Due to a typo, G ' In the case of both cases, 'G or H ' Simply press the control button labeled with the new character, including the character that was originally targeted to the character already entered, including the character entered due to a typo. Like embodiments Can be replaced immediately.

Because only two characters are assigned to the same button, the remaining characters that are not just entered Only one  Because.

2. As the control button at the bottom of the display screen as shown in Fig. 34, all the characters assigned to the 'DF' character button, which is the character button assigned to the character 'F' which was input immediately before (cursor), 'D, F' Is assigned to (eg marked) control buttons

Pressing a control button with 'D' assigned (e.g.) can cause 'F' to be replaced by 'D' directly.

(If so, now, the control buttons

(Cursor) In the state that there are control buttons with 'D' and 'F' assigned to all the characters assigned to 'DF' character button assigned to 'D'

If you press a control button with 'F' assigned (e.g. marked), you can have 'D' replaced with 'F'.)

<Deletion: Not required>

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

While reviewing the above Example 1 again, let's look at the meaning of the implied phrases claimed herein.

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

Even when 'SO POO' was correctly entered (not shown), I tried to input the last character 'R', but the wrong 'Q' was entered by incorrectly operating the 'PQRS' character button assigned 'R'. That is, as shown in FIG. 39, 'SO POOQ' is inputted due to a typo in a character input window in 'AREA-D', and the cursor is positioned immediately after 'Q' inputted with a typo, such as 'AREA-D'. .

When the state is as described above, the first step proceeds.

" First step: the step of identifying the character of the position derived by the position definition of the specific relationship with the cursor position or state in the character input window ".

(In the first step,

It is recommended that the position derived from the cursor position or state in the character input window and the position definition of a specific relationship be the position immediately before the cursor.)

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

(However, the position is defined as to whether this embodiment, as the current cursor position immediately before or immediately after the immediately preceding, as well as just before and off much back and forth from the cursor, including just after just after the location is determine depending on in advance.)

Then, in the end, the 'character of the position derived by the positional rule (1) of the specific relationship with the cursor position and state' means a character to be changed in the future, and in this embodiment, the character immediately before the cursor, which is input due to a typo. That is, ' Q' .

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

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

In general, since the cursor state in a portable electronic device including a smartphone is the INSERT mode in the desktop PC, the cursor position is the position just before the cursor in this embodiment, but in the NOT INSERT mode in the desktop PC, the current cursor position itself is changed. It would be most desirable to use 'cursor position and state and position derived by specific relationship definition'.

(However, the rules are pre-determined, including that you can specify how far back and forth from the cursor, including just before, just after, or just before or after the cursor, even in the NOT INSERT mode.)

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

In this situation,

Conventionally, a user deletes 'Q' inputted due to an error by pressing a delete button and inputs 'R' which was originally intended to be input,

In the present disclosure, the user may change the 'Q' to 'R' without deleting the 'Q' input due to a typo. This will be explained in detail.

Second step: identifying one or more characters except for the character identified in the first step of the two or more characters assigned to the character button on the keyboard assigned the character identified in the first step

To describe the above two-stage phrase, for example with Figure 39,

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

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

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

' One or more characters ' excluding two or more characters assigned to the character buttons on the keyboard assigned to the character identified in the first step,

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

' Step 3: The step of assigning one or more characters (any one or more characters) identified in the second step to one or more control buttons '

(In the third step,

All of the one or more characters identified in the second step is assigned to one or more control buttons. Assigned  It is recommended.

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 be displayed.)

In the third step, the word 'control button' first appears, and the 'control button' may be referred to as a button that functions to change an already input character into 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 control button (s) are assigned the characters identified in step 2.

That is, the character assigned to the control button (s) will continue to change as the cursor position and input continues.

That is, in the present embodiment, the characters 'P', 'R', or the characters grasped in the second step to the control button (s) of '1 BUTTON', '2 BUTTON', or '3 BUTTON' of FIG. 'S' is assigned.

In this embodiment, 'P', 'R', or 'S' assigned to the control button in Fig. 39 is displayed.

(The control button '1 BUTTON' is assigned 'P' and displayed.

The control button '2 BUTTON' is assigned 'R' and displayed,

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

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

The assigned letter 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 means that only the character including the arrow indicating the direction may be displayed instead of the assigned character, and the state of the button display may be blank.

The characters recognized in the second step are expected to be relatively simple as in the present embodiment even in most cases where the technique of the present invention is applied by someone in the future, so that it is expected that there is no big problem even if the display behavior of the control button is blank. This is because even if the control button in FIG. 25 is not labeled as 'A' or 'D'

If the provisions for Stage 2 and Stage 3

('Q') inputted immediately before the cursor (cursor), the character ('Q') inputted just before the cursor (the cursor among the characters assigned to the button assigned to the 'PQRS' character button)

If the character ('Q') entered immediately before (cursor) is assigned to the control button in the order of assignment (= display) from the assigned button ('PQRS' character button),

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

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

It is easy to see that 'S' will be assigned to the control button '3 BUTTON' (an embodiment of the behavior indicated by the arrow will be shown later).

Step 4: One of the one or more control buttons is selected, and a character assigned to the selected control button (or displayed after the assignment) is grasped

To describe the above phrase through this embodiment, the control button assigned the letter in step 3, 'P', 'R', or 'S' assigned '1 BUTTON', '2 BUTTON', When the control button ('2 BUTTON' in FIG. 39) is touched and selected from the control button (s) called '3 BUTTON', the letter assigned to the selected control button is naturally 'R'. Will be figured out.

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

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

To explain a little more, due to a typo in AREA-D of FIG. 39, the input 'Q' can be replaced with 'R' immediately. (In the end, 'SO POOQ' will be changed to 'SO POOR'. city))

That is, the conventional concept is not to input 'R' after the user deletes 'Q'.

In the fifth step,

The process of changing the text identified in step 1 to the text found in step 4

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 inputted after the character identified in the first step is deleted.

To describe the above phrase through this embodiment,

In the above, the method of the present application merely changes a character input (e.g. 'Q') due to a typo to a character originally intended (e.g. 'R'), but it is the user's conception or visual. easy,

In electronic technology concept,

Touching the control button ('1 BUTTON' in FIG. 39) labeled 'R' at the bottom of the display screen of FIG. 39,

You can implement 'Q' to be replaced by 'R' directly,

Alternatively, 'Q' may be deleted almost immediately and 'R' may be input so that the user's eyes may be implemented to appear to be replaced by 'Q' without 'Q' being deleted.

The above Examples  In short, the following explanations are given.

In devices that input characters through the keyboard (in the way of correcting characters entered immediately before due to typos)

(The character entered immediately before by the user, practically without any step being deleted)

realistically, One time  By generating a signal,

Characters entered immediately before are replaced with a character of a specific relationship with the character.

To

'Character of a specific relationship'

' The character entered on the same button as the button to which the immediately preceding character is assigned has a specific relationship, including a specific spatial relationship or a specific assignment sequence relationship, with the character entered immediately before. It can be a way.

Front In the embodiment  Although described with specific assignment order relationships, they may also be specific spatial relationships.

E.g, In Figure 17  The form assigned P, Q, R, S can also be said to indicate the order in which each letter is assigned. As in Figure 17  If not written in four directions, up, down, left, and right, there is 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  Top, bottom, left, right, top, bottom, Lower left , Idol, or Uha  Directional control buttons may be required. Of course, each direction button may be disposed separately.

(Not required here where the characters are displayed on the control button)

Thus, the above abbreviated phrase can be modified more specifically as follows.

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

The character entered immediately before is assigned to the same button as the assigned button.

The character assigned to the same button as the button to which the character entered immediately before is assigned to the button, or the order assigned to the button.

Characterized in that the character entered immediately before is a character having a specific relationship with the assigned position or order. '

And the rules about the position of the cursor and the position of the character that is modified by the new character are up to you.

As in the embodiments up to now, the character input immediately before the current cursor position may be modified through the character correction control button,

The character entered immediately before the character entered just before the current cursor position can be modified through the character modification control button.

Than the character entered just before the current cursor position. 2 characters  First, you can modify the entered text through the text editing control button,

Characters entered immediately after the cursor position can be modified through the character correction control button,

The character entered immediately after the character entered 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 later it is possible to modify the characters entered through the character correction control button,

The rules for the character position relationship modified by operating the cursor position and the character modification control buttons are determined.

As in the previous embodiments, the character input immediately before the current cursor position is changed through the character correction control button. To be corrected  It is best recommended.

Thus, the aforementioned 'character entered immediately before' can be described more comprehensively by replacing 'character at the prescribed position with respect to the current cursor position'.

In the above description, the third step is a step in which one or more characters identified in the second step are assigned to one or more control buttons.

One or more characters identified in step 2

It may or may not be displayed on the control button,

So far

Only the examples shown are described.

From now on, the text is not displayed on the control button, but a simple method of not displaying the text on the control button including the control button indicated by the arrow will be described.

Literally, until the one or more characters identified in the second step are assigned to the control button, it is the same as the above-described embodiment, but the control button is not displayed as a letter, but the first to fifth steps. The process up to is the same.

Thus, in the drawings cited in the above embodiments, only the drawings in which the texts displayed on the control buttons are changed to the arrows may be easily understood without detailed description by substituting the embodiments and the descriptions according to the situation.

Therefore, the drawings in which characters are displayed on the control buttons cited in the above embodiment, and the drawings in which characters are changed into arrows, will be paired with the following.

Fig. 15 is not required in the control button embodiment in which the characters are displayed, but is required only in the control button embodiment, which is not shown in Fig. 35, which is a variation of Fig. 15.)

In the above-mentioned embodiment, the drawings in which the drawings are cited when the control buttons are not displayed as letters will not be described, but will be briefly described.

4 is a diagram illustrating an embodiment of a smart phone having a virtual keyboard on a touch screen to which the present technology is applied. Compared to the conventional general smart phone virtual keyboard as shown in FIG. 1, a control button ('LEFT BUTTON' of FIG. 4) and a right arrow (Right in FIG. 4) are displayed at the bottom of FIG. BUTTON ').

[In fact, if the present technology is applied to a smart phone, in the conventional smart phone drawings as shown in 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 present technology, a control button ('LEFT BUTTON' of FIG. 3) and a right arrow indicated by a left arrow are shown. Arrangement where the button ('RIGHT BUTTON' in FIG. 3) is positioned in place of the conventional shift and delete buttons, or

The position of the shift button and the delete button as shown in FIG. 20 is the same as in the related art, and as a control button for applying the present technology, a control button indicated by a left arrow ('LEFT BUTTON' in FIG. 20) and a control button indicated by a right arrow (RIGHT BUTTON, Fig. 20) is placed next to the conventional space button seat

But it will be explained on the basis of FIG. 4 in order to improve the unity and understanding with the following description of various embodiments.

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

The following briefly describes the conventional technology applied to the Samsung Galaxy S described in the section 'Technology behind the invention'.

If a letter button (for example, '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 popup is formed directly above the button.

When a touch on a letter button is released, the popup disappears, and the color of the letter button touched before is returned to the same color as other buttons.

However, when applying the technology of the present application, when the indication of the touched button starts to be implemented slightly differently as follows, when the technology of the present application is further progressed later, the user clearly knows which character button was the button touched immediately before. The user will be more convenient. (However, even if it starts to be implemented as before, the technology of the present application is not impeded.)

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

If a character button is touched, the color of the character button changes color differently from other buttons, and a popup is formed directly above the button.

When the touch of a character button is released, the disappearance of the pop-up disappears. However, the color of the character button that has been touched immediately before is maintained in a different color from that of the other buttons. When a new button is touched, It is recommended that the colors be the same as those of the other.

(But, in fact, it would have been better if the prior art was implemented in the above-mentioned method. In the prior art, since the pop-up formed near the touched letter button disappears at the same time the finger is released from the letter button. In addition, in actual use, since the touch time is very short, it is difficult to accurately recognize the characters in the popup.)

The following process also proceeds under the assumption that the technique is applied to the present application in the same manner as described above.

As shown in Figure 4, in the process for entering the 'SO GOOD' in the character input window in 'AREA-D' of Figure 4,

At the time of entering 'SO GOO' correctly (not shown), I tried to input the last letter 'D', but after the wrong 'S' letter button was touched, my finger was released. S is entered in the character input window in D ', and as shown in' AREA-D 'of FIG. 5, the cursor is positioned immediately after the' S 'input by a typo.

And, assume that the color of the 'S' button is displayed differently from other buttons as shown in FIG. 5 (in the end, 'SO GOOS' has been entered.)

In this situation,

Conventionally, due to typos, S ' The user deletes it by pressing the delete button, D ' , But

In this application, due to a typo, S ' Without deleting the user, S ' ' D ' Can be changed to

For example, referring to FIGS. 5 and 6,

At the bottom of the display screen of Fig. 5,

Of the button assigned to the immediately preceding character ('S') (that is, the letter button 'S')

'A' assigned to the letter button ('A' letter button) on the left is assigned to the control button ('LEFT BUTTON' in Fig. 5) indicated by the left arrow,

The 'D''D' assigned to the character button ('D' character button) on the right side is assigned to the control button ('RIGHT BUTTON' in FIG. 5) marked with a right arrow.

The user may touch the control button ('RIGHT BUTTON' in FIG. 5) displayed with the right direction arrow to directly replace 'S' inputted due to the typing of AREA-D in FIG. 5 into 'D' , And 'SO GOOD'.

(Or, in consideration of the user's idea, it is assumed that the color in the 'S' character button which is currently mistakenly touched as shown in FIG. 5 is moved to the 'D' character button originally intended to be input as shown in FIG. ('RIGHT BUTTON' in FIG. 5) displayed on the bottom right side is displayed, it is possible to directly replace 'S' inputted due to the typing of AREA-D into 'D' have.)

That is, it is not a concept of inputting 'D' after the user deletes 'S' as conventionally.

(In the description of the embodiment of the present application, the touched button is intended to remain different from other buttons even after the touch is released, so that the color on the 'S' letter button is originally input as shown in FIG. 6. You can think of it as a 'D' letter button, but you can also implement the techniques of the present application, just like a conventional color-shifting method, as soon as the touch is released to return the same color as the other buttons. Can not change the traditional desktop The physical keyboard of PC will also be able to apply the correcting method of typos, though the effect is not great .

In the above, the method of the present application refers to a technique of directly replacing a character (for example, 'S') input due to a typo, with a character (for example, 'D') originally intended, but it is a user's idea or visual. I mean,

In electronic technology concept,

If you touch the control button ('RIGHT BUTTON' in FIG. 5) indicated by a right arrow at the bottom of the display screen of FIG. 5,

You can also implement 'S' to be replaced by 'D' directly,

Alternatively, you can implement 'S' to be deleted (automatically), enter 'D' almost instantly, and eventually replace 'S' with 'D'.

Let's look at another embodiment to better understand the technology of the present disclosure, including making it clear that the characters assigned to the control buttons can vary.

In the process for entering 'SO GOOD' in the text input window as shown in Figure 4,

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

 And, assume that the color of the 'F' character button is displayed differently from other buttons as shown in FIG. 7 (after all, 'SO GOOF' has been entered).

In this situation, conventionally, the user deletes the inputted ' F' due to the typos and inputs the ' D' that was originally intended to be input. However, in this embodiment, the user does not delete the ' F' ' F' can be changed to ' D' .

For example, with reference to Figures 6 and 7,

Of the button assigned to the immediately preceding character ('F') (that is, the 'F' character button)

'D' assigned to the character button ('D' character button) on the left is assigned to the control button ('LEFT BUTTON' in Fig. 7) indicated by the left arrow,

The 'G' assigned to the letter button ('G' letter button) on the right is assigned to the control button ('RIGHT BUTTON' in FIG. 7) marked with a right arrow.

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

(Or the user's idea, think of moving the color of the 'F' character button that was wrongly touched as shown in FIG. 7 to the 'D' character button originally intended to enter as shown in FIG. Touch the control button (LEFT BUTTON in Fig. 7) with the left arrow on the bottom, and immediately replace 'F' entered as a typo in 'AREA-D' in Fig. 7 with 'D' as in Fig. 6. I can throw it away.)

That is, it is not a concept to input 'D' after deleting 'F' as in the past.

<Delete: Delete as duplicate except alphabet>

In the above method of the present application is a character entered due to a typo (eg ' F ' ) Originally targeted to a character (e.g. " D ' It's a technology that replaces with), but that's the idea of the user,

In electronic technology concept,

7 Display screen  A control button with a left arrow at the bottom ( 7  ' LEFT BUTTON ' ),

' F ' Going ' D ' Can be implemented directly as

Or, it is almost instantly a 'F' (automatically) to remove, the 'D' is input, the end may also be implemented to be 'F' is replaced by 'D'.

Of course, the techniques herein can be applied while moving the cursor position.

For example, a character entered immediately before a shifted cursor position may be replaced by a new character including an originally targeted character, including a character input due to a typo, without a user deleting a character.

<Deletion: Not required>

(For reference, in the above embodiments, when the cursor is displayed, L ' Lower case ' l ' I did not show it because it seemed to be confused with.

For example, when 'SO GOOD' is input, when the cursor is moved between the 'S' and 'O' of 'SO' as shown in FIG. 42,

In the first step, if the position derived by the position definition (1) of a specific relationship with the cursor position or state in the character input window is 'position immediately before the cursor',

The character identified in the 'first step: the step of identifying the character of the position derived by the position definition (1) of a specific relationship with the cursor position or state in the character input window' is

Become '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) indicated by a left arrow,

'D' assigned to the letter button (= 'D button') located in the right direction of the 'S letter button' is assigned to the control button ('RIGHT BUTTON' in FIG. 42) indicated by a right arrow. By touching the control button labeled 'A' ('LEFT BUTTON' in FIG. 42), it is possible to replace 'S' with 'A' immediately (in the end, inputted as 'AO GOOD' (not shown). )

-------------------------------------------------- -------------------- <Deletion: Plot factually redundant>:

In short, the contents of the above paragraphs

Characters entered immediately by the user, "substantially", replace characters already entered, including characters entered due to typos, with new characters, including those originally intended, without the step of deleting them. I can say that.

The word "substantially" above

As explained in the paragraphs above

A character entered due to a typo (e.g. " F ' ) Originally targeted to a character (e.g. " D ' ), Literally, you can replace it right away,

A character entered due to a typo (e.g. " F ' ), The user can delete the original target character (e.g., &quot; D ' Just by touching the control button assigned)

A character entered due to a typo (e.g. " F ' ) Is deleted momentarily and then the originally targeted character (eg ' D ' ) Is entered,

A character entered due to a typo (e.g. " F ' ) Originally targeted to a character (e.g. " D ' Includes meanings that can be replaced with).

As in the above embodiment, in a virtual keyboard that appears when a character is input by standing a conventional smartphone vertically, since the horizontal length of each letter button is an elongated rectangular shape in the vertical direction less than the vertical length, in most cases a typo The occurrence is often caused by incorrectly touching a character button located to the left or right of the button originally targeted.

So, when applying the present technology to the virtual keyboard as shown in Figure 1 when the smartphone is put up vertically when entering the character, the original character, including the character entered due to the typo originally aimed at As a control button for changing to a new character including a character, a control button marked with a left arrow or a right arrow as in FIG. 3 or 4 may be sufficient.

However, when the horizontal length of each character button is larger than the vertical length as shown in FIG. 9, that is, since each character button is formed in an elongated rectangular shape from side to side, in most cases, a typo occurrence is immediately above or immediately after the originally targeted button. It is often caused by incorrectly touching the letter button located in the lower direction.

In the case of applying the technique of the present application to a keyboard in which the width of each character button including Fig. 9 is larger than the height, new characters including a character originally intended for an already inputted character including an input character due to a typo are displayed. As a control button necessary for changing to a character, a control button marked with an up arrow or a down arrow as shown in FIG. 10 may be sufficient.

If a left arrow, a right arrow, an up arrow, and a down arrow are also required, control buttons may be provided as shown in FIG.

The control button in Fig. 12 is a four-way arrow shown in Fig. 11 displayed on one button. After being displayed at once, the device can accept the expression of the user's direction by touching the area of the arrow head in the desired direction.

If only the left arrow and the right arrow are desired to be displayed on one button at a time, the control buttons on the bottom of the display screen of FIG. 16 can be used. (In fact, the direction display control button in Fig. 16 is used for a slightly different purpose than the control button described above in the description of the embodiment using Fig. 16).

Let's take a look at a case where another character assigned to a character button assigned to a character entered immediately before (cursor) is assigned.

<Deletion: Former claim>

now

'realistically, One time  By generating a signal,

The character entered immediately before is replaced by a character having a specific relationship with the character.

'Character of a specific relationship'

'The character entered immediately before and the character entered in the same button as the button  (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 shown in FIG. 14, 17, or 21, when a typo occurs, the user deletes previously input characters including the characters input due to the typo, as described above. Without, substantially, generating one signal,

I will explain how to replace the character entered immediately before with the character originally targeted.

When a plurality of characters are assigned to the same button as shown in Fig. 14, 17, 18, or 21,

Since the size of the character button is quite large, it is very rare to operate the wrong character button rather than the intended character button.

I originally touched the letter button,

In many cases, a wrong button operation is used to mistype a character originally intended.

The reason for this is briefly mentioned in the section entitled 'Background of the invention', and will not be repeated here.

I will only explain how to replace characters already entered, including characters entered due to typos, with characters originally intended without the user deleting them.

First, let me explain by example.

In the final process of inputting 'SO POOR' to the character input window of AREA-D 'in the display screen as shown in FIG. 17, FIG. 18 or FIG. 21,

Even though 'SO POO' was correctly entered (not shown), I tried to input the last character 'R'. If the assigned 'Q' is entered (after all, 'SO POOQ' is entered), you can correct the typo in several ways as follows.

1. As the control button at the bottom of the display screen as shown in Fig. 21, the character entered immediately before of 1,2,3,4, which means the order of the characters assigned to the character button to which the character entered immediately before is assigned. When there are control buttons with numbers 1, 3, and 4 except 2, the order of

By pressing control button 3, 'Q' may be replaced by 'R' which is the third letter among the letters assigned to the button assigned to 'Q'.

The above phrase is described in detail as follows.

As the control button at the bottom of the display screen as shown in Fig. 21, the letters 'P, Q, R, S' assigned to the letter button 'PQRS', which is the letter button assigned to the character 'Q' immediately inputted (cursor) (P = 1, Q = 2, R = 3, S = 4 if the order is indicated by numbers) 'P, R, S' which is characters except 'Q' which is the character entered immediately before (Cursor) Is represented by numbers, P = 1, R = 3, S = 4)

Are assigned to the control buttons. To describe the assignment in detail,

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

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

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

In this state, by pressing the control button labeled '3' assigned 'R', 'Q' can be replaced by 'R' directly.

(If proceed as above,

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

Are assigned to the control buttons. To describe the assignment in detail,

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

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

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

In this state, pressing the control button labeled '2' to which 'Q' is assigned may cause 'R' to be replaced by 'Q' directly.)

2. As a control button at the bottom of the display screen as shown in Fig. 18, there is a control button displaying 1,2,3,4 indicating the order of the characters assigned to the character button to which the character entered immediately before is assigned. In

By pressing control button 3, 'Q' may be replaced by 'R' which is the third letter among the letters assigned to the button assigned to 'Q'.

The above phrase is described in detail as follows.

As the control button at the bottom of the display screen as shown in Fig. 18, the letters 'P, Q, R, S' assigned to the letter button 'PQRS', which is the letter button assigned to the character 'Q' which is input immediately before (cursor), (P = 1, Q = 2, R = 3, S = 4 if the order is represented by numbers)

Are assigned to the control buttons. To describe the assignment in detail,

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

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

'R' is assigned to a control button labeled '3' ('C BUTTON' in FIG. 21)

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

In this state, by pressing the control button labeled '3' assigned 'R', 'Q' can be replaced by 'R' directly.

(If proceed as above,

(Cursor) 'P, Q, R, S' assigned to the character button 'PQRS' character button assigned to 'R' assigned to the previous character (P = 1, Q = 2, R = 3, S = 4)

Are assigned to the control buttons. To describe the assignment in detail,

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

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

'R' is assigned to a control button labeled '3' ('C BUTTON' in FIG. 21)

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

In this state, if the control button labeled '2' is assigned to 'Q', 'R' can be replaced by 'Q' immediately.)

3. As a control button at the bottom of the display screen as shown in Fig. 17, in a state where there is a control button indicated by left and right arrows

Pressing the control button marked with the right arrow once replaces the 'R' displayed immediately to the right of the 'Q' in the 'PQRS' character button, which is the same character button as the assigned 'Q' It can be done.

(If you press the control button marked with the right arrow twice, 'Q' will be replaced by the second assigned 'S' to the right of 'Q'.)

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

The above phrase is described in detail as follows.

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

The control button marked with a left arrow to which the letter 'P' assigned immediately to the left (= before) and

With the control button marked with the right arrow to which the letter 'R' assigned to the right (= before) is assigned,

If you press the control button marked with the right arrow to which 'R' is assigned, 'Q' may be replaced by 'R'.

(If proceeded as above, now,

(Cursor) 'P', 'P', 'P', 'P', 'Q' is assigned to 'PQRS' character button.

The control button marked with a left arrow to which the letter ('Q') assigned immediately to the left (= before)

With the control button marked with the right arrow to which the letter 'S' assigned to the right (= before) is assigned,

If 'Q' presses a control button that displays a right arrow assigned a left arrow, 'R' may be replaced by 'Q' directly.)

The third embodiment

In the third step,

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

And, as shown in Fig. 19, the control buttons of Figs. 17 and 18 may be arranged at a time.

17 and 18 may be applied to a keyboard in which only one or two characters are assigned to the same button as in FIGS. 14 and 16. In particular, in this case, as long as only one control button as shown in Figure 16 will not matter.

The reason for this is as follows.

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

An attempt was made to enter 'G', but 'H' was entered due to a typo or

If you tried to enter 'H', and you pressed the control button with the double-headed arrow in both cases where 'G' was entered due to a typo, you could return the previously entered characters, including those entered due to typos. From the new character, including the target character, can be replaced immediately, as in the above embodiments.

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

Note that,

17, 18, and 21, the above-mentioned embodiment 1, 2, 3 is a character button having only two characters assigned to the same button as in the keyboard as shown in Figs. The same applies to existing keyboards.

In the keyboard shown in FIG. 14 or FIG. 16, during the last process of inputting 'SO GOOD' into the character input window of 'AREA-D',

If you wanted to enter 'D' as the last character, and you entered the wrong 'F' assigned to the same letter button as 'D' (after all, 'SO GOOF' was entered), There are several ways to correct typos (the following method is best recommended):

1. As the control button at the bottom of the display screen as shown in Fig. 16, the characters assigned to the 'DF' character button assigned to the letter button 'F' assigned immediately before the (cursor) among the characters 'D, F' ( Cursor) When there is a control button with a left and right double-headed arrow to which a letter 'D' is assigned, except for the letter 'F',

By pressing the control button assigned 'D', 'F' can be replaced by 'D' directly.

(If the above progresses, now, the control button

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

If you press the control button marked with the left and right arrows with 'F' assigned, 'D' can be replaced by 'F'.)

(Because 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 character other than the character entered immediately before.)

<Deletion: Not Needed>

In particular, in this case Like Figure 36  It's okay to have only one control button.

Why Examples  Through the following description.

Figure 36  When entering characters using the same keyboard,

' G ' I tried to type in. Due to a typo, H ' Is entered or

' H ' I tried to type in. Due to a typo, G ' In the case of both cases, 'G or H ' Simply press the control button labeled with the new character, including the character that was originally targeted to the character already entered, including the character entered due to a typo. Like embodiments Can be replaced immediately.

Because only two characters are assigned to the same button, the remaining characters that are not just entered Only one  Because.

2. As the control button at the bottom of the display screen as shown in FIG. Is assigned to two control buttons,

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

'F' is assigned to the control button marked with the right arrow.

At this time, if the control button 'D' is assigned (for example, displayed), 'F' may be replaced with 'D' immediately.

(If so, now,

(Cursor) All the characters assigned to the letter button 'DF', which is the letter 'D' entered just before, are assigned to the two control buttons.

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

'F' is assigned to the control button marked with the right arrow.

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

To control buttons

15 is substantially the same as FIG.

just,

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

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

The above Examples  In short, the following explanations are given.

In devices that input characters through the keyboard (in the way of correcting characters entered immediately before due to typos)

(The character entered immediately before by the user, practically without any step being deleted)

realistically, One time  By generating a signal,

Characters entered immediately before are replaced with a character of a specific relationship with the character.

To

'Character of a specific relationship'

' The character entered on the same button as the button to which the immediately preceding character is assigned has a specific relationship, including a specific spatial relationship or a specific assignment sequence relationship, with the character entered immediately before. It can be a way.

Front In the embodiment  Although described with specific assignment order (= indicated order) relationship, it may be a specific spatial relationship.

E.g, In Figure 18  The form assigned P, Q, R, S can also be said to indicate the order in which each letter is assigned. As in Figure 18  From left to right to clearly see the order assigned PQRS ' If it is not written in the formula, and the same control button is written in four directions of up, down, left, and right, there is a specific spatial relationship. Figure 11 Display screen  You may need control buttons marked with the up, down, left and right arrows at the bottom. or Of Figure 13 Display screen  Top, bottom, left, right, top, bottom, Lower left , Idol, or Uha  You may need a control button with a directional arrow. Of course, each direction button Like Figure 11  It may be arranged separately.

Thus, the above abbreviated phrase can be modified more specifically as follows.

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

The character entered immediately before is assigned to the same button as the assigned button.

The character assigned to the same button as the button to which the character entered immediately before is assigned to the button, or the order assigned to the button.

Characterized in that the character entered immediately before is a character having a specific relationship with the assigned position or order. '

The character input method described so far can be applied to any language other than the languages mentioned. For example, it is applicable to Greek / Roman, Cyrillic, Arabic, Southeast Asian, Indic, Thai, Vietnamese, and language specific languages such as English, French, German, Spanish, etc.

In addition, although the method of the present application has been described so far with only an example of correcting an error caused by incorrectly touching a character button, the present invention can be applied to a function button instead of a character button.

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

So far, we have discussed how to change an already-input character including input characters to a new character including a character originally intended due to a typo.

From now on, we will look at how the user can easily distinguish what was the button that was operated just before.

Quite simply, for example,

In input mode , where only single touch with one finger is used ,

(When the first button is touched,

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

The first touched button (e.g. the first button),

Until a new, different button (e.g. a second button) is touched, display it differently (e.g. from a different color)

-After a new button (e.g. second button) is touched, it is displayed differently (e.g. in the same color) from other buttons (except the second button).

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

(A little easier to say:.

A first button, which is a button that has been touched immediately before,

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

Distinguishably from one or more other buttons,

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

In an input mode using up to multi-touch that touches a plurality of buttons or a plurality of touch points using two or more fingers,

(If the first target button is recognized,

The 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 (for example, the first target button) recognized by the previous touch,

Until a new single touch or multi-touch is initiated (or until another target button (e.g., a second target button) recognized by the new single-touch or multi-touch is recognized), differently from the other buttons (eg Display in different colors)

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

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

(A little easier to say,

In the input mode that is used up to multi-touch ,

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

Until a new single-touch or multi-touch is started, or until a second target button, which is another target button recognized by the new single-touch or multi-touch, is recognized,

Distinguishably from one or more other buttons,

After the start of the new single-touch or multi-touch or after the second target button, which is another target button recognized by the new single-touch or multi-touch, is recognized,

One or more buttons other than the first target button are displayed indistinguishably.

In the present disclosure, a method of displaying a specific button distinguished from other buttons may include not only a method of changing the color presented in the embodiments of the present disclosure, but also a different button.

Shape, color (color, brightness, saturation), illuminance, luminance, luminous intensity, luminous flux, luminous flux divergence,

It is also envisioned that any one or more of the above elements may change.

For example, you can blink by varying the light intensity, make the button zoom in and zoom out,

Everything that can visually distinguish a particular key from another key is included.

In the present application, the meaning of a button in the phrase that a particular button is distinguished from other buttons does not only mean the area inside the button, but also includes the outside of the button rectus.

For example, the 'N' character button may have a different color (eg, gray) from the surroundings of the other buttons (eg, white), such as the 'N' button of FIG. 48.

(Of course, the 'N' character button may have a different color (eg, gray) from the inside of the other buttons, such as the 'N' character button of FIG. 46.

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

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

To understand the implications well,

As described above, the keyboard of the embodiment will be described to feel as if there is only a letter button for inputting only three characters of 'D, N, O'.

(Although it's easier to understand this with a keyboard concept with more than 26 common buttons, the premise of the implicit phrase is a device with more than three buttons, so you can only enter three characters. If you explain it to feel like a keyboard with only letter buttons, it's a bit confusing, but it's better to understand the implications.

If you have only three letter buttons, you can faithfully share the roles of one button and the other two buttons that were touched immediately before.)

First, as soon as you touch the input mode that uses only a single touch that touches with one finger The touch button will be described in the case of the system that is displayed to be distinguished from the other button.

Step A1: starting a touch on the first button.

For example,

(Because the letter 'O' button was touched immediately before, as shown in Fig. 44, the letter 'O' could be displayed in a different color (e.g., gray) to distinguish it from other buttons (e.g., 'D, N' letter buttons). there is,)

At this time, as shown in FIG. 45, the touch on the 'D' character button, which is the first button, is started.

Step A2: The first button Touch  The button which was displayed to be distinguished from two or more other buttons from before is displayed without being distinguished from one or more buttons which are not the button and the first button,

Displaying the first button separately from at least two buttons other than the first button.

For example,

Like Figure 45,

The 'O' button, which is displayed in a different color (for example, gray) from two or more other buttons ('D, N' character buttons) before the first button 'D' character button is touched, (E.g., white) so as not to be distinguished from one or more buttons (e.g., an 'N' character button) other than the 'D'

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

Step A3: the step of releasing the touch of the first button.

For example,

The first button 'D' letter button is a step in which the touch is released (for example, a finger is removed from the touch screen).

Phase A4: Phase A2 results are maintained or phase A2 is re-implemented.

In plain words,

If step A3 goes on, that is, the touch is released,

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

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

To explain a little more,

If step A3 goes on, that is, 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 the same color as other buttons (for example, white), so it is difficult to recognize which button is the button touched immediately before.

(Although, conventionally, as shown in Fig. 47, a popup (also referred to as a 'preview') indicating a button on which a touch is maintained (e.g. 'D' letter button) is also known. Even though the 'D' button is enlarged to 4 times larger than the 'D' button), as soon as the touch is released, the popup also disappears, so the popup is only shown for a very short time. , The user is hard to see properly, and after a while they don't know at all.)

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

To explain a little more,

The second stage is maintained or the second stage is implemented again, but in effect, is the same,

Literally,

Before the touch of the 'D' character button, which is the first step, the 'button', which was displayed in a different color (eg, gray), was distinguished from two or more other buttons ('D, N' character buttons) The O 'character button is the same color (e.g. white) indistinguishable from one or more buttons (e.g.' N 'character buttons) that are neither its' O' character button nor its' D 'character button. ),

The first button 'D' is kept in a different color (e.g. gray) to distinguish it from two or more buttons ('O, N'buttons) that are not' D 'buttons. , The results from step A2 remain the same

Before the touch of the 'D' character button, which is the first step, the 'button', which was displayed in a different color (eg, gray), was distinguished from two or more other buttons ('D, N' character buttons) The O 'character button is the same color (e.g. white) indistinguishable from one or more buttons (e.g.' N 'character buttons) that are neither its' O' character button nor its' D 'character button. ),

Enforcement will be represented by: (gray for example) 're-claim the 1 button, the' D 'letter button has two or more buttons than the' D 'character buttons to be distinguished from the (' O, N 'character buttons) different colors It becomes .

A5 step: the second button is a touch is initiated.

For example,

As shown in Fig. 46, the touch on the second button 'N' is started.

Step A6: the step of displaying the first button indistinguishable from one or more buttons that are neither the first button nor the second button .

For example,

46, the first button 'D' letter button,

The step of displaying the same color (for example, white) is not distinguished from one or more buttons other than the first letter button 'D' and the second button 'N'.

(For reference, eventually,

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

E.g,

The second button 'N' letter button,

(Eg, gray) distinctly from two or more buttons (such as the "D, O" character button) rather than the second button, the "N"

Now, will be described a yet finger single touch to touch the only type used mode when the system is a touch-button only after the touch release shown to be distinct from the other button two kinds of (B1 ~ B5 step, C1 ~ C6 step) .

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

Since the same description as in the step A1 can be applied here, the description is omitted.

Step B2: the step of releasing the touch on the first button.

Since the same description as in the step A3 can be applied here, the description is omitted.

Since the same description as in the step A6 can be applied here, the description is omitted.

( Note that eventually, the second button is displayed differently from the two or more buttons, not the second button. )

Now let's look at the case of multi-touch input mode.

When a multi-touch in which a state in which a plurality of buttons is touched is made in an area in which a plurality of buttons exist, there is a concept of a target button about which button a user actually touches among a plurality of touched buttons.

For example, in the keyboard as shown in FIG. 44

If the target button recognizing method at the time of multi-touch is a rule in which a button including the lowest touch point among the multi-touched touch points is recognized as a target button,

When the user touches the X letter button correctly with the index finger so that the X letter button becomes the target button, the middle finger and the ring finger are trying to touch anywhere above the index finger.

If the multi-touch, where the index finger is touching the X letter button, the middle finger is touching the Y letter button, and the ring finger is being touched, the X letter button will be properly recognized as the target button. If the rumor of the letter assigned to the ground target button is entered, the lowercase x will be entered instead of the uppercase X.)

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

If the target button recognizing method at the time of multi-touch is a rule in which a button including a touch point that is first touched among multi-touched touch points is recognized as a target button is applied

The user first touched the X character button so that the X character button becomes the target button, and the stop and the ring finger tried to touch any time later than the index finger,

The index finger was first touched, but by the X letter button,

When the stop was touched after the index finger, but the F letter button was touched,

If the fingerprint is touched after the stop and the multi-touch where there is a state in which all three fingers are touched while touching the Y character button is made, the X character button will be correctly recognized as the target button. (If multi-touching is used, if the rule is to input the rumor of the character assigned to the target button, the lowercase x will be entered instead of the uppercase X.)

If the method for recognizing the target button in the multi-touch is a system in which a rule is applied to recognize a button including the touch point touched last among the multi-touch points as the target button, the Y letter button will be recognized as the target button. (If the rule is to enter the rumors of the characters assigned to the target button when multi-touch is made, the lowercase y will be entered instead of the uppercase Y.)

As described above, when the multi-touch is performed , the first touch The button containing the touch point is recognized as the goal button.

Therefore, the multi-touch proceeds, that is, which touch As the number of touch points increases, the target button may be changed according to the complex relationship between the multi-touch order relationship, the positional relationship of the multi-touch points, the multi-touch order and the position of the multi-touch points . (Of course, the target button may not change.)

For example,

In the description of the target button recognition method at the time of multi-touch in which the above-described X, F, and Y character buttons are exemplified, when the first touched character button is the X button and the target button recognition method selects the highest touch point among the multi- On the system where the containing button is recognized as the target button

If a finger touches the X character button on the index finger, the F character button on the stop, and the Y character button on the finger ring,

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

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

However, in the description of the target button recognition method at the time of multi-touch in which the above-described X, F, and Y character buttons are exemplified, when the first touched character button is the X button and the target button recognition method is the lowest touch On a system where the rule that the button containing the point is recognized as the target button is applied

If a finger touches the X character button on the index finger, the F character button on the stop, and the Y character button on the finger ring,

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

That is, the first character button, which is the first character button to be touched, is the first target button, and the first target button remains as the X character button even after the multi-touch process.

It is further understood that the first target button and the second target button used in the following connotation phrase can be easily understood by changing the concept of the first button and the second button in the system having only a single touch.

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

(And, When the final target button recognition time for multi-touch is multi-touch This is a case where a condition that is a point where even one touch point decreases is added, i.e., a condition where the target button cannot be changed even if the number of multi-touch touch points starts to decrease.)

D1 step : Single touch  Steps undertaken

Regardless of whether the user attempts to single touch or multi-touch, that is, not all fingers are touched at the same time even if the user tries to multi-touch, single touch is achieved based on the first touch criteria.

And since the current condition is a system in which as soon as any touch is made (a button recognized as a target button) is displayed differently from other buttons, single touch is started.

For example,

('O' character button was recognized as a target button just before the display as shown in FIG. 44, so the 'O' character button is displayed in a different color (for example, gray) to distinguish it from other buttons (for example, 'D, N' character button). Might have been)

At this time, as shown in Fig. 45, the single touch on the 'D' character button (recognized as the first target button in step D2) is started.

D2 step : Single touch  A button is recognized as a first target button

For example,

The letter button 'D', which is a single touch button, is recognized as the first target button.

D3 steps: the first target button, the button having been shown to be two or more distinct and different buttons even before the touch, and displayed so that button is not the first target button is not distinct from the one or more buttons is not the first target button The step of distinguishing from two or more buttons other than the first target button;

For example,

Like Figure 45,

The button 'O', which was displayed in a different color (for example, gray) from two or more other buttons ('D, N' character buttons) before the first target button 'D' (For example, white) so as not to be distinguished from one or more buttons (for example, the 'N' character button) other than the first target button, the 'D' Lt; / RTI &gt;

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) other than the 'D' letter button.

D4 Step: If the first D1 At the stage Single touch With multi touch  When it proceeds, Multi-touch  Step in which the first target button can be changed as it progresses

'As mentioned above, when multi-touch is made , the first touch is The button containing the touch point is recognized as the goal button.

Therefore, the multi-touch proceeds, that is, which touch As the number of touch points increases, the target button may be changed according to the complex relationship between the multi-touch order relationship, the positional relationship of the multi-touch points, the multi-touch order and the position of the multi-touch points . (Of course, the goal button may not change), see the phrase and its surroundings, especially the description below.

D5 step :

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

Before change  The first goal button, Before change  Not the first goal button After change  It is displayed indistinguishably from one or more buttons other than the first target button,

After change  The first goal button, After change  It is displayed differently from two or more buttons other than the first target button.

if, D5 If the first target button has not changed as the step progresses, D3 The stage is maintained or D3 The phase in which the phase is redone.

For example,

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

The 'D' character button as the first target button before the change does not correspond to the 'D' character button as the first target button before the change, and the one or more buttons (for example, &Quot; N &quot; character buttons), the same color (e.g., white)

The 'O' letter button, which is the first target button after the change, is different from two or more buttons (for example, the 'D, N' letter buttons) other than the 'O' letter button, which is the first target button after the change. Example: Gray).

If the 'D' letter button recognized as the first target button in step D2 is maintained as the 'O' letter button while the first goal button is still intact while going through step D4, the 'D' letter button remains gray. In other words, the result of the step D3 is maintained or the step D3 is executed again.

D6 Step: Step of releasing even one touch.

The step of releasing the touch to end the touch for the user to recognize the first target button as multi-touch is now started.

Until step D5, if the number of touch points can be increased after the single touch (more and more, if not single touch only), but cannot be decreased, that is, until the step D5, the touch with the maximum number of touch points intended by the user. Is the step that takes place,

Here, step D6 is a step in which the user completes the multi-touch and starts to release the multi-touch, in which the touch point is first reduced. Therefore, the phrase 'even one touch' is in the phrase.

D7 Step: Step of determining the final first target button

Since step D6 in the description of step D6 is a step in which the maximum number of touches intended by the user is made, the step D7 where the step D6 elapses is a step in which the final first target button can be determined.

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

For example,

In a system in which a rule for recognizing a target button is applied to a target button during multi-touch, a button including a touch point touched last among the multi-touch points is recognized as the target button.

The user touches the Y letter button last so that the Y letter button becomes the target button, and the index finger and the middle finger are trying to touch it any time before the index finger.

The index finger was first touched, but by the X letter button,

If the middle finger is touched next to the index finger and multi-touch is in progress until the character button is touched,

The current first target button is a letter F button.

However, if the touch map was touched next to the stop, but the touch of the Y letter button and all three fingers were in a state where the touch was made, 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 may be changed.

D8 Steps: All touches are released.

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

D9 step : Single touch  Steps undertaken.

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

Regardless of whether the user attempts to single touch or multi-touch, that is, not all fingers are touched at the same time even if the user tries to multi-touch, single touch is achieved based on the first touch criteria.

And since the current condition is a system in which as soon as any touch is made (a button recognized as a target button) is displayed differently from other buttons, single touch is started.

For example,

As shown in FIG. 45, a single touch for the 'N' character button as the first button is started.

D10 Step: The final first goal button is displayed indistinguishably from one or more buttons that are neither the final first goal button nor the second goal button.

For example,

One or more buttons (e.g., 'O' character button that is not the final 'D' character button, which is the first target button, is not the 'D' character button, which is the final first target button, or 'N' character button, which is the second target button) ) Is the same color (for example, white).

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

For example, to illustrate,

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, (For example, gray).

Now, not only single touch with one finger but also multi-touch A description will be given of a system in which the input mode to be used and the button recognized as the target button are displayed so as to be distinguished from the other buttons .

(And, There is added a condition that a point at which the (final) target button for the multi-touch is recognized is the point at which all the multi-touched touch points are released . In other words, even if the number of multi-touch touch points starts to decrease, there is a condition that the target button may change when the number of touch points increases. Also, the condition that the time when the first target button is displayed differently from the other buttons is released is added as a condition that the user starts the new single touch or the multi-touch for recognizing the second target button as multi-touch.)

E1 step : Single touch  or Multi-touch  Undertaken.

For example,

('O' character button was recognized as a target button just before the display as shown in FIG. 44, so the 'O' character button is displayed in a different color (for example, gray) to distinguish it from other buttons (for example, 'D, N' character button). Might have been)

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

E2 Steps: All touches are released.

And releasing all the touches to completely terminate the touch for allowing the user to recognize the first target button as multi-touch. That is, there is no touch point at which the display screen is touched.

E3 Step: Recognizing what the first target button is.

For example,

The letter button 'D' is recognized as the first target button.

E4 Step: The first goal button Touch  Buttons that have been displayed to be distinguished from two or more other buttons before are displayed indistinguishably from one or more buttons which are neither the buttons nor the first target buttons, and the first target buttons are two not the first target buttons. The step of being distinguished from the above buttons.

For example,

Like Figure 45,

The button 'O', which was displayed in a different color (for example, gray) from two or more other buttons ('D, N' character buttons) before the first target button 'D' (For example, white) so as not to be distinguished from one or more buttons (for example, the 'N' character button) other than the first target button, the 'D' Lt; / RTI &gt;

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) other than the 'D' letter button.

E5 step : Single touch  Steps 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 multi-touch.

Regardless of whether the user attempts to single touch or multi-touch, that is, not all fingers are touched at the same time even if the user tries to multi-touch, single touch is achieved based on the first touch criteria.

In addition, although the current condition is a system in which a button (recognized as a target button) is displayed differently from other buttons only after all touches are released, the time when the first target button is displayed to be distinguished from other buttons is released. Since the target button is a new single touch or a multi-touch start point for the user to recognize the multi-touch, the single touch is started.

For example,

As shown in FIG. 45, a single touch for the 'N' character button as the first button is started.

E6 Step: The first target button is not the first target button, E5 In step Single touch  The steps are displayed so that they are not distinguished from one or more buttons other than buttons.

For example,

If the 'D' character button as the first target button is not the 'D' character button as the first target button but one or more buttons (for example, 'O' character button) other than the 'N' (For example, white) so as not to be distinguished from the other colors.

(Note that the second target button has not yet been determined so that three or more buttons ('D, N, O' character buttons) may be displayed in the same color (e.g., white) to be.)

Now, not only single touch with one finger but also multi-touch A description will be given of a system in which the input mode to be used and the button recognized as the target button are displayed so as to be distinguished from the other buttons .

(And, (Final) time point the condition that the target button when the recognition of any touch point is multi-touch release for the multi-touch is also a case to be added. In other words, even if the number of multi-touch touch points starts to decrease, there is a condition that the target button may change when the number of touch points increases. Further, there is also added a condition that the point at which the first target button is distinguished from the other buttons is released when all the new single-touch or multi-touch touch points for recognizing the recognition of the second target button are released.

F1 stage: Single touch  or Multi-touch  The steps taken

Since the same description as in the above step E1 can be applied here, the description is omitted.

Step F2: Steps to release all touches

Since the same description as in the above step E2 can be applied here, the description is omitted.

F3 step: Recognizing what the first target button is

Since the same description as in the step E3 can be applied here, the description is omitted.

F4 steps: the first target button, the button having been shown to be two or more distinct and different buttons even before the touch, neither the button to display not the first target button is not distinct from the one or more buttons is not the first target button The step of distinguishing from two or more buttons other than the first target button;

Since the same description as in the step E4 can be applied here, the description is omitted.

F5 stage: Single touch  or Multi-touch  Undertaken.

In this step, a single touch or multi-touch is newly performed for the user to recognize the second target button as multi-touch.

For example,

As shown in Fig. 46, a multi-touch is started to be made so that the 'N' character button is single-touched or the 'N' character button is recognized as the target button.

Step F6: All the touches are released.

For example,

And releasing all the touches to completely terminate the touch for letting the user recognize the multi-touch of the second target button 'N'. That is, there is no touch point at which the display screen is touched.

Step F7: The first target button is displayed so as not to be distinguished from one or more buttons other than the first target button and the second target button.

For example,

The 'D' character button as the first target button may be one or more buttons (e.g., 'O' character buttons) other than the 'D' character button as the first target button and the 'N' character button as the second target button (For example, white) so as not to be distinguished from each other.

(For reference, the second target button is displayed so that it can be distinguished from two or more buttons other than the second button.

For example,

The 'N' character button as the second target button is displayed in a different color (for example, gray) so that it can be distinguished from the two or more buttons ('D, O' character button) Is displayed.)

It is possible to apply a method for distinguishing buttons operated just before as described above from other buttons regardless of the language of the world mentioned. For example, it is applicable to Greek / Roman, Cyrillic, Arabic, Southeast Asian, Indic, Thai, Vietnamese, and language specific languages such as English, French, German, Spanish, etc.

In addition, although the method of the present application has been described as an example that only the character button is the button operated immediately before, the present invention can be applied to a function button instead of the character button.

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