4 is a flowchart illustrating a text input method of a mobile terminal according to an embodiment of the present invention.

As a mobile terminal composes a message, writes an e-mail, or enters a search word while connecting to the Internet, or writes a memo, the mobile terminal inputs letters to other terminals or sites to communicate with each other. Or show the user the desired information.

When the user inputs a character in the mobile terminal, if a typo occurs or there is a word to add, the user moves to the position to be edited and edits it. In this case, the mobile terminal is provided with a touch screen to move the cursor to a point touched by the user and to output a direction key on the screen to move the cursor freely according to the touched direction key.

As shown in FIG. 4, the controller 180 displays a data input screen for text input on a touch screen when writing a message, a mail, or a memo (S410).

A touch signal is received through the first area of the input screen on which characters are displayed (S420). The user may touch the first area of the input screen by using a touch pointer (for example, an index finger). Then, the controller 180 determines that a touch signal is received through the first area.

The controller 180 displays a cursor in the first area (S430). In general, a cursor is displayed on the input screen to guide an input position of a character. The cursor may be displayed after a character positioned at the end of the characters in the input screen or between characters. The user touches an area to place the cursor on an input screen on which characters are to be changed to change the position of the cursor, and the controller 180 moves the cursor to the touched area without considering the position of the existing cursor. do.

Meanwhile, while the touch signal through the first area is received, the controller 180 receives the touch signal through the second area of the input screen in operation S440. That is, the user may touch the second area with another touch pointer (for example, a middle finger) while touching the first area.

Then, the controller 180 moves the cursor horizontally, but moves and displays the moved cursor so as to be closer to the second area (S450). In moving the cursor, the controller 180 may move the cursor in correspondence with at least one of a reception time of the touch signal received through the second area and a number of times of reception of the touch signal. Can be.

Meanwhile, the controller 180 determines whether a user command for displaying a keypad has been received (S460). When a keypad is provided in one region of the touch screen or one region of the portable terminal, it is not necessary to input a separate keypad display command. However, if the keypad is not provided, the user can enter a keypad display command.

When a keypad display command is input (S460-Y), the controller 180 displays the keypad on one region of the touch screen (S470). More specifically, the controller 180 divides the touch screen into two sub areas, displays at least a portion of an input screen on which characters are displayed on one sub area, and displays a keypad on the other sub area. When displaying a portion of the input screen on the sub-area, the controller 180 preferably displays an input screen including the area where the cursor is located, and displays an indicator indicating that there is an input screen that is not displayed. Can be.

The controller 180 generates and displays a character corresponding to the touched key of the keypad in the area where the cursor is displayed (S480). Specifically, the user may input a character generation command while touching a key in the keypad. Then, the controller 180 generates characters in the order in which the keys of the keypad are touched and displays them in the area where the cursor is displayed, and moves the cursor to the next one of the generated characters.

As such, when an additional touch signal is received while the touch signal is received, the cursor may be moved more finely because the cursor is moved in units of characters so that the additional touch signal is closer to the received region.

Then, the controller 180 displays the cursor 520 in the touched first area 512. If the cursor 520 is already displayed in the area 510 where the character is displayed, the cursor 520 may be moved to the first area 512 for display. If the cursor is not displayed, the controller 180 may display the cursor 520. The cursor 520 may be generated to display the cursor in the first area 512.

And, as shown in (b) of FIG. 5, the user touches the first area 512 with the middle finger and using the ring finger, the second area 514 on the right side of the first area 512. ) Can be touched. Then, the controller 180 moves the cursor 520 in units of characters according to the number of times of receiving the touch signal through the second area 514. For example, when the user touches the second area 514 four times using the ring finger, the controller 180 moves the cursor to the right in units of characters whenever a touch signal is received. As a result, the controller 180 moves the cursor from the first area 512 to the area having the four right characters and displays the cursor. In addition, the user may touch an icon 530 labeled as an input window to input a keypad display command.

Then, as illustrated in FIG. 5C, the controller 180 divides the region 510 in which the text is displayed into the first sub-region 540 and the second sub-region 550, and the first sub-region. In operation 510, at least a portion of the previously displayed text is displayed, and a cap is displayed in the second sub area 550. When all characters previously displayed in the first sub-area 540 cannot be displayed, the controller 180 may display the cursor 520 and the characters in the area adjacent to the cursor 520. The user touches the keys included in the keypad, and as shown in (d) of FIG. 5, the controller 180 generates a character 542 by using a combination of the touched keys and displays the cursor 520 in the area where the cursor 520 is displayed. do. The cursor 520 then displays the next area of the generated character 542. As such, the user may move the cursor more precisely with an additional touch input in the touched state.

6 is a reference view illustrating a method of changing the display magnification of an image according to an exemplary embodiment of the present invention.

As illustrated in (a) of FIG. 6, in the display magnification changing mode, one region 612 of the image 610 displayed on the user screen may be touched with a middle finger. Then, the controller 180 displays the indicators 620 and 630 for guiding the change of the display magnification in the region adjacent to the touched region 612. The first indicator 620 is an icon for guiding a decrease in the display magnification, and the second indicator 630 is an icon for guiding an increase in the display magnification. The user may input a display magnification change command by touching an area in which the first indicator 620 is displayed or an area in which the second indicator 630 is displayed. For example, as illustrated in FIG. 6C, when the user touches a region 610 of the image with a middle finger, when the user touches a region where the second indicator 630 is displayed with a ring finger, the controller In operation 180, the display magnification is increased in response to the number of touches, and a portion of the image in which the display magnification is increased is displayed. When displaying a portion of the image, as shown in FIG. 6D, it is preferable to display a portion 640 of the image around the image of the region where the middle finger is touched.

In the present embodiment, a method of changing the display magnification of the image by an additional touch input while touching is described, but is not limited thereto. In addition to the display magnification of the image, the display magnification of other data (for example, text) displayed on the touch screen may be changed.

As described above, since the user can input a plurality of mutually equivalent user commands such as reducing or increasing the display magnification with an additional touch input in the touch state, the operation of the portable terminal is facilitated.

 The display magnification may be changed in correspondence with the number of touch points and the distance dragged, as well as additional touch input in the touched state. For example, when a user command of dragging the first distance is received in the state where two touch points are generated, the controller 180 may double the display magnification and display the result. When a user command of dragging a distance is received, the controller 180 may increase the display magnification by three times and display the same. As described above, since the display magnification can be changed in correspondence with the number of touch points, the user can check the screen changed to the desired display magnification in one operation.

In addition, the additional touch input or the multi-touch input in the touched state may be utilized as various user commands.

When a user wants to input a command for executing a favorite menu, as shown in FIG. 7A, in a screen 710 in which a plurality of menus are listed as items, a fourth menu including a favorite menu is included. A single touch on the region 712 marked with may display a sub-menu display command of the fourth menu. Then, as illustrated in (b) of FIG. 7, a screen 720 listing submenus of the fourth menu is displayed. In the area where the second sub-menu is displayed, an icon 722 indicating that the preference is set as the preferred menu is displayed. With the icon 722, the user can confirm that the second sub-menu is set as the preferred menu. The user may input a command to execute the second sub menu by single touching the second sub menu, and the controller 180 may execute an execution screen of the second sub menu as illustrated in (c) of FIG. 7. 730).

On the other hand, the user may input a preferred menu execution command by multi-touch on the screen 710 in which a plurality of menus are listed as items. For example, in FIG. 7A, when the user multi-touches the area 712 on which the fourth menu is displayed, the controller 180 controls the multi-touch to execute the command of the preferred menu among the sub-menus of the fourth menu. In addition, the display of the screen illustrated in FIG. 7B may be omitted, and the execution screen 730 of FIG. 7C may be displayed by executing the preferred menu.

In this way, by setting the menu navigation method differently according to the single touch and the multi-touch, the operation of the portable terminal is simplified.

8 is a reference diagram illustrating a method of changing a playback speed of a video by multi-touch according to an embodiment of the present invention.

As shown in FIG. 8, while the playback screen 810 of the video is displayed, the controller 180 divides the playback screen into two sub-areas. When a touch signal is received in the first subregion 812 of the subregions, the touch signal is recognized as a user command to change the playback speed slowly. Then, the playback speed is changed to correspond to the number of touch points to play back the video. However, when a touch signal is received in the second subregion 814 of the subregions, the touch signal is recognized as a user command for quickly changing the reproduction speed. Then, the playback speed is changed to correspond to the number of touch points to play the video. For example, the user may simultaneously touch the second sub-region 814 using the index finger, the middle finger and the ring finger. Then, three touch points are generated on the touch screen, and the controller 180 plays the video by increasing the playback speed three times.

As described above, since a command for changing the playback speed of the video can be input in correspondence with the number of touch points, the user's manipulation of the portable terminal becomes easy.

The scroll speed when inputting a scroll command for the screen may also be set differently according to the number of touch points.

9 is a reference diagram illustrating a change in scroll speed according to the number of touch points according to an embodiment of the present invention.

As illustrated in (a) of FIG. 9, in a screen 910 including an area of an electronic document, a user may input a scroll command after touching an area where the electronic document is displayed. Here, the electronic document refers to a document type data that is created, transmitted or received in electronic form by a device having an information processing capability such as a computer. In addition, the electronic document includes all files containing data that can be displayed on the screen. For example, an electronic document includes all files capable of displaying a list of a plurality of items such as a phone book or a message list, a text-based content, a web page or other graphic image, and the like. The scroll command may be input by a touch flick or a touch and drag operation.

According to the scroll command, the display portion, which is an area displayed on the touch screen, is moved and displayed in the electronic document. When the display portion moves, the controller 180 moves the display portion at a moving speed corresponding to the number of touch points, that is, a scrolling speed. For example, if the user inputs a scroll command 930 after touching the first area 920 with one finger, as shown in FIG. 7B, the controller 180 can display the electronic device at a preset scroll speed. The display portion of the document is moved to display a screen 940 including an area of the electronic document in which the display portion is changed. However, when the user touches with two fingers and inputs a scroll command, the controller 180 may move and display the display portion of the electronic document at twice the preset scroll speed.

As such, since the scroll speed may be changed according to the number of touch points, the user may input a user command more dynamically.

Then, the controller 180 receives a multi-touch user command (S1120). The controller 180 reads an image related to a specific image displayed in the memory according to a multi-touch user command (1130). Here, the related image may be an image including the same object as an object included in a specific image or an image connected with meta data. Alternatively, the image may be an image captured on the same date as the specific image. The related image is preferably displayed in the form of a thumbnail image.

On the other hand, the controller 1130 determines whether there are a plurality of related images read out (S1140). When there are a plurality of related images 1114-Y, the controller 180 displays the related images by overlapping them (1150). When displaying the related images in a superimposed manner, the controller 180 preferably displays a pop-up window in one region of the region where the specific image is displayed. The user may input a user command of dragging a pointer of one of the touch pointers. Then, the controller 180 determines that a user command of dragging one of the multi-touches has been received (S1160), and displays the image related to the dragged path in unfolded (S1170). When unfolding and displaying a related image, the controller 180 may delete a display of a specific image and unfold and display an image related to a touch screen. If the dragged trajectory is part of an ellipse, if the dragged trajectory is part of an ellipse, the shape of the related image is also part of the ellipse. it means.

However, when there is one related image, the controller displays one image in one region of the specific image. In addition, the related image is preferably displayed as a thumbnail image.
