The controller 180 receives a user input for opening a text window ( S101 ). The controller 180 may receive a user input for opening a text window through the touch sensor. The text window may be an electronic document including text, or may be a text tool window in which text editing such as inputting, copying, pasting, modifying, deleting, and restoring text may be performed through user input. In the text tool window, text may be input in advance through user input.

The controller 180 opens a text window corresponding to a user input for opening the text window ( S103 ). For example, the controller 180 may open a selected electronic document, a selected web page, or a selected text tool window.

The controller 180 displays the opened text window and enters the screen moving mode ( S105 ). According to an embodiment, the screen moving mode may be a mode in which the display screen of the display unit 151 moves in units of pages through a user input.

In another embodiment, when the text window is opened, the screen moving mode may be automatically released. For example, when the text tool window for text editing is opened, the controller 180 automatically cancels the screen moving mode so that the display screen of the display unit 151 is not moved even if a user input for screen moving is received. Can be.

The controller 180 receives a user input for enlarging the text displayed in the text window ( S107 ), and enlarges the text according to the user input for enlarging the text ( S109 ). According to an embodiment, the user input for enlarging text may be a long touch in a text area displayed in a text window.

The controller 180 may enlarge the entire text displayed in the text window or enlarge some text displayed in the text window through a user input for text enlargement. This will be described in detail with reference to FIGS. 3 to 4.

3 to 4 are diagrams illustrating a process of enlarging text through a user screen according to an exemplary embodiment of the present invention.

First, referring to FIG. 3, when a long touch is detected in a text area through a user input, the controller 180 may enlarge and display the entire text. According to an embodiment, the controller 180 may enlarge and display the text based on the touch point at which the long touch is detected, but need not be limited thereto. The controller 180 may detect the long touch when the long touch is detected. Regardless of the location of the touch point, text can be enlarged and displayed at the same rate.

If the long touch is detected and the text is enlarged, and then the touch is not detected for 1 second, the enlarged text may be maintained, and if the red touch is detected, the enlarged text may return to the original size text. have.

Next, referring to FIG. 4, when a long touch is detected in the text area through a user input, the controller 180 enlarges some text located near the touch point based on the touch point at which the long touch is detected. The magnification box 200 may be displayed. That is, the text enlargement box 200 may enlarge only some text located near the touch point around the long touch point, and may not enlarge text not located near the touch point. In an exemplary embodiment, the vicinity of the touch point may be up, down, left, and right, and text located at a diagonal of the touch point with respect to the touch point, but this is only an example and may be changed according to a user's setting. The size of the text enlargement box 200 may be smaller than or equal to the size of the user screen.

According to the embodiments of FIGS. 3 and 4, when the text size (font) is small, the controller 180 enlarges and displays the text through the detection of the long touch so that the user can easily edit the text.

2 will be described again.

The controller 180 receives a touch movement in a state where the text is enlarged ( S111 ).

In one embodiment, the touch movement may be one touch movement while the touch is maintained on the text. This will be described later with reference to FIG. 5.

In another embodiment, the touch movement may refer to repeated touch movement in which the touch is repeatedly moved while the touch is maintained on the text. Specifically, the touch is repeated on the unit text (one word), which may mean an operation in which the user rubs on the unit text by repeated touch movement. This will be described later with reference to FIG. 6.

5 to 6 are user screens showing a touch movement according to an embodiment of the present invention.

First, FIG. 5 is a user screen showing one touch movement in the state of FIG. 3, that is, in an enlarged text. Referring to FIG. 5, one touch movement is performed on the text of the 'Daughton' unit. That is, the touch is moved while the touch is maintained on the 'Daughton' unit text.

FIG. 6 is a user screen illustrating a process of repeating touch movement in the state of FIG. 3, that is, in a state where text is enlarged. Referring to FIG. 6, one or more touch movements are repeated on the 'Daughton' unit text. That is, one or more touch movement repetitions are performed while the touch is maintained on the 'Daughton' unit text.

The controller 180 checks whether the received touch movement repetition satisfies the condition for entering the touch movement deletion mode ( S113 ). When the received touch movement movement input satisfies the condition for entering the touch movement deletion mode, the controller 180 moves. The mode of the terminal 100 enters the touch movement deletion mode ( S115 ).

According to an embodiment, the condition for entering the touch movement deletion mode may be satisfied when at least one of the speed or the number of touch movements exceeds the reference speed or the reference number. For example, when the speed of the touch movement exceeds the reference speed, or when the number of touch movements exceeds the reference number, or when the number of touch movements exceeds the reference number, while the speed of the touch movement exceeds the reference speed. In this case, the controller 180 may change the mode of the mobile terminal 100 from the screen movement mode to the touch movement deletion mode.

Here, the reference speed and the reference number may vary according to the user's setting.

For example, referring to FIG. 5, when a touch movement is made once on the unit text 'Daughton', when the speed of the touch movement exceeds the reference speed, the controller 180 touches the mode of the mobile terminal 100. You can enter the move delete mode. In this case, the screen moving mode in which the screen moves in units of pages may be maintained, and when the speed of the touch movement is less than the reference speed, the screen may move to a page including text different from the current text.

6, when the touch movement is repeated on the unit text 'Daughton', when the speed of the touch movement exceeds the reference speed and the number of touch movements exceeds the reference number, the controller 180 determines that the mobile terminal is a mobile terminal. The mode of 100 may be entered into the touch movement erase mode. Here, the reference number may be twice, as shown in FIG. 6, but this is merely an example.

In another embodiment, the touch move deletion mode entry condition may be established by a touch of an additional touch move deletion mode entry button. This will be described with reference to FIG. 7.

7 shows a user screen according to an embodiment of the present invention.

Referring to FIG. 7, when a touch movement deletion mode entry button 300 is displayed on one side of the user screen, and a touch is detected once in the touch movement deletion mode entry button 300, the controller 180 controls the mobile terminal. 100 may be entered in the touch movement erase mode. If a touch is detected once more by the touch movement deletion mode entry button 300, the touch movement deletion mode may be released.

According to another embodiment of the present invention, the touch movement deleting mode entry button 300 must be continuously maintained so that the mode of the mobile terminal 100 can be maintained in the touch movement deleting mode. In this case, if the touch of the touch movement deletion mode entry button 300 is not detected, the controller 180 may release the touch movement deletion mode.

The touch movement delete mode entry button 300 may be included in a text input window (not shown) for inputting text and displayed.

2 will be described again.

The touch movement delete mode is a mode in which text can be deleted according to a touch movement. In detail, the touch movement deletion mode may be a mode in which the text may be deleted while showing the process of deleting the text according to the repetition of the touch movement. More specifically, the touch movement deletion mode may be a mode in which the corresponding text may be deleted by right and left repetition of the touch movement or up and down repetition of the touch movement.

When the mobile terminal 100 enters the touch movement deletion mode, the controller 180 may notify that the touch movement deletion mode has been entered. According to an embodiment, the controller 180 may change the color of the text displayed on the user screen or the color of the background area of the text, thereby notifying the user that the mobile terminal 100 has entered the touch movement deletion mode.

In another embodiment, the controller 180 may notify that the mobile terminal 100 has entered the touch movement deletion mode through a separate guide message UI.

When the mobile terminal 100 enters the touch movement deletion mode, the controller 180 notifies that the text to be repeated for the touch movement is to be deleted ( S117 ). According to an embodiment, the controller 180 may indicate a deletion process of the text by displaying a strikethrough on the text that is the target of the touch movement repetition.

In another embodiment, the controller 180 may display a text deletion process by changing the color of the text that is the target of the touch movement repetition. This will be described with reference to FIGS. 8 to 9.

8 to 9 are user screens for notifying a text deletion process according to an embodiment of the present invention.

First, FIG. 8 is an exemplary embodiment in which a deletion line is displayed on text that is a target of touch movement repetition to inform a process of deleting text.

Referring to FIG. 8, when the touch movement is repeated three times from side to side on the unit text 'Daughton', the controller 180 displays a strikethrough on the unit text 'Daughton' to recognize that the corresponding text is to be deleted to the user. I can let you. Three times here is just an example.

In addition, when the touch movement is repeated three times on the unit text 'Daughton', the controller 180 may enter the mode of the mobile terminal 100 into the touch movement erase mode and display a strikethrough line.

In an embodiment, the position of the strikethrough line may be displayed across the center of the unit text, but it is not necessarily limited thereto, and may be displayed in correspondence to the moving direction of the touch.

Next, referring to FIG. 9, when the touch movement is repeated three times on the unit text 'Daughton', the controller 180 changes the unit text 'Daughton' color from black to gray to remove the corresponding text from the user. Can be recognized.

Alternatively, unlike the embodiment of FIG. 9, the controller 180 may display the color of the unit text differently according to the number of touch movements. For example, as the number of touch movements increases, the controller 180 may recognize that the text is to be deleted by gradually fading the color of the text.

2 will be described again.

The controller 180 confirms that the text deletion condition is satisfied while notifying that the text to be repeated for the touch movement is to be deleted ( S119 ). If the text deletion condition is satisfied, the controller 180 deletes the text ( S121 ).

According to an embodiment, the text deletion condition is a condition for deleting text according to the detection of the touch movement, and it may be determined whether the number of repetitions of the touch movement on the text exceeds the reference deletion count. Specifically, when the number of repetitions of the touch movement on the text is five or more times, the text deletion condition may be satisfied. Here, five times is only an example. This will be described with reference to FIG. 10.

10 is a user screen for deleting text according to an embodiment of the present invention.

FIG. 10 illustrates a process in which the controller 180 deletes the text when the text deletion condition is satisfied while the text deletion notification of FIG. 8 or 9 is displayed.

For example, if the touch movement is detected three times on the unit text 'Daughton' and two more touch movements are detected (five times in total) while the text deletion notification of FIG. 8 or 9 is displayed, the controller 180 Delete the unit text 'Daughton'.

According to an embodiment, even if a touch movement is detected on a portion of the unit text 'Daughton', the controller 180 may delete the entire unit text 'Daughton'. Specifically, touch moves this unit text? Even if a touch movement is detected on 'Daugh' which is a part of 'Daughton', the controller 180 may delete the entire unit text 'Daughton'.

That is, in the exemplary embodiment of the present invention, even if a text deletion condition is satisfied in a portion of the unit text, the entire unit text may be deleted.

2 will be described again.

On the other hand, if it is determined that the text deletion condition is not satisfied, the controller 180 determines whether the text recovery condition is satisfied ( S123 ), and when the text recovery condition is satisfied, the controller 180 recovers the text ( S125 ).
