The camera 121 'may have a photographing direction substantially opposite to the camera 121 (see FIG. 2A), and may be a camera having different pixels from the camera 121.

For example, the camera 121 may have a low pixel so that the face of the user can be photographed and transmitted to the other party in case of a video call or the like, and the camera 121 ' It is preferable to have a large number of pixels. The cameras 121 and 121 'may be installed in the terminal body so as to be rotatable or pop-upable.

Hereinafter, an object display control method using a multi-touch of a mobile terminal according to the present invention will be described in detail with reference to the drawings.

3 is a flowchart illustrating a method of moving and zooming an object using a multi-touch of a mobile terminal according to an embodiment of the present invention.

The control unit 180 of the mobile terminal 100 displays various objects on the display screen by controlling the display unit 151 according to the control command (input data) output from the user input unit 130 (S101). The object includes an image, a content, a widget, an item, a menu, an icon, a pop-up window, and the like. For example, when the home button or the end button of the user input unit 130 is input, the controller 180 outputs a standby screen to the display unit 151 and displays one or more widgets on the standby screen according to preset information .

The control unit 180 senses the first touch input on any one of the objects displayed on the display screen through the sensing unit 140 (S102). When the sensing unit 140 senses the touch of a pointer such as a user's finger on the display screen, the sensing unit 140 transmits the coordinate value of the touch point that the pointer touches to the controller 180. The controller 180 stores the coordinate value received from the sensing unit 140 in the memory 160 and identifies an object corresponding to the coordinate value. When the touch point is moved (dragged) while the touch is maintained, the sensing unit 140 senses the touch point and detects the coordinate value of the touch point to be moved and transmits the coordinate value to the control unit 180. In other words, the controller 180 senses a touch and drag that occurs on a predetermined object through the sensing unit 140. Here, the controller 180 highlights and displays the touched object in order to distinguish the touched object from the non-touched object. For example, the control unit 180 may emphasize the touched object by adjusting brightness, color, size, shade, engraving, and the like.

If the first touch input is detected, the controller 180 moves the touched object according to the first touch input (S103). When the controller 180 detects touch and drag on a predetermined object displayed on the display screen, the controller 180 moves the touched object along the movement path by the touch and drag. In other words, the control unit 180 continuously receives the coordinate value corresponding to the touch point moving through the touch and drag from the sensing unit 140 and moves the predetermined object to one point of the display screen corresponding to the coordinate value . Here, the controller 180 moves the object corresponding to the point where the touch is detected according to the moving distance and direction by the touch and drag. For example, when a user touches a predetermined object with a finger and moves the finger while holding the touch, the controller 180 moves the predetermined object along the touch point of the finger.

Then, the controller 180 senses the second touch input through the sensing unit 140 (S104). In other words, when the second touch input is further generated on the object moved by the first touch input, the controller 180 senses the second touch input through the sensing unit 140. [

If the second touch input is sensed, the controller 180 determines whether the first touch input is maintained (S105). Here, if the second touch input is detected while the first touch input is continuously being performed, the controller 180 recognizes the touch input as multi-touch. If the second touch input is detected while the first touch input is released It recognizes it as a single (single) touch.

If it is determined that the first touch input is continued, the control unit 180 enlarges or reduces the moved object according to the second touch input (S106). For example, if the first touch input is maintained and further touch and drag occurs, the controller 180 senses additional touch and drag through the sensing unit 140, and detects the additional touch and drag (Dragging distance) and the moving direction (dragging direction). Then, the control unit 180 enlarges or reduces the size of the moved object according to the calculated movement distance and movement direction. Here, the controller 180 determines an enlargement / reduction ratio in accordance with the calculated movement distance, and determines an enlargement / reduction direction based on the calculated movement direction.

If it is determined that the first touch input is released, the controller 180 moves the moved object again according to the second touch input (S107).

FIG. 4 illustrates an example of moving and enlarging a widget using a multi-touch in a mobile terminal according to an embodiment of the present invention.

The control unit 180 of the mobile terminal 100 displays indicators indicating the operation status of the terminal on the idle screen and displays button icons such as a keypad, a phone book, a message, and a menu. 4 (a), the controller 180 may display at least one or more predetermined widgets 301 and 301 'on the display screen.

The controller 180 senses the first touch 302 through the sensing unit 140 when the first touch 302 is input to one point on the specific widget displayed on the display screen. The sensing unit 140 detects a coordinate value of the first touch point at which the first touch 302 is generated and transmits the coordinate value to the control unit 180. In other words, the sensing unit 140 informs the control unit 180 that the touch input has occurred. When the controller 180 receives the coordinate value of the first touch point generated by the sensing unit 140, the controller 180 stores the received coordinate value in the memory 160 and waits.

Then, the sensing unit 140 transmits coordinate information on the first touch point, which is changed when the first touch 302 senses movement (drag) of the first touch point, to the control unit 180 . The control unit 180 moves the clock widget 301 according to coordinate information received from the sensing unit 140 (a). For example, when a touch and drag is input from a first point where the clock widget 301 is located on the display screen to a second point on the display screen, the controller 180 controls the clock widget 301 according to the touch and drag, From the first point to the second point.

The sensing unit 140 notifies the control unit 180 of the occurrence of the second touch 303 when the second touch 303 is sensed on the clock widget 301 after the movement of the first touch point. When the controller 180 detects the second touch 303, the controller 180 determines whether the first touch 302 is continuing. If the first touch 302 continues, the control unit 180 recognizes the input as a multi-touch input and recognizes the first touch 302 as a single-touch input if the first touch 302 is released. If the second touch 303 is generated on the clock widget 301 while the first touch 302 is being held and then the second touch point of the second touch 303 is moved, Enlarges or shrinks the clock widget 301 (c). Here, the controller 180 adjusts the size of the clock widget 301 based on the moving direction and the moving distance of the second touch point. For example, as shown in Fig. 4 (c), when the first touch 302 is held in the clock widget 301, the second touch 303 is generated on the clock widget 301, When the drag is input, the controller 180 enlarges the clock widget 301 in the right direction. In addition, the controller 180 determines the enlargement or reduction ratio of the clock widget 301 based on the distance that the second touch point moves by dragging, and controls the clock widget 301 only in the direction in which the second touch point moves 301). That is, when the distance between the second touch point and the first touch point increases, the controller 180 enlarges the clock widget 301 in the direction in which the second touch point moves, and when the distance between the second touch point and the first touch point increases, The clock widget 301 is reduced in the direction in which the second touch point moves.

FIG. 5 illustrates an example of enlarging an object included in an image when an image is edited using a multi-touch in a mobile terminal according to an exemplary embodiment of the present invention.

5, the control unit 180 selects an image to be edited according to a control command input from the user input unit 130, and outputs the selected image to the display unit 151. FIG. The display unit 151 displays the selected image on the display screen under the control of the controller 180.

Upon receiving an edit request from the user input unit 130, the control unit 180 enters an image edit mode in which an image can be edited. In the image editing mode, when the user desires to insert the speech balloon into the selected image, the user selects the speech balloon by operating the user input unit 130, and the controller 180 controls the selected speech balloon according to the selection command input from the user input unit 130 The speech balloon 311 is displayed on the display screen. At this time, the control unit 180 inserts the selected speech balloon 311 at an arbitrary point of the image displayed on the display screen and displays the inserted speech balloon 311 (a). For example, the control unit 180 inserts the selected speech balloon 311 in the center of the image and superimposes the selected speech balloon 311 on the image.

When the touch button 312 is input on the speech balloon 311 displayed on the display screen, the sensing unit 140 detects the touch and notifies the controller 180 of the touch. When the drag is inputted to the touch 312, the controller 180 senses the touch and drag through the sensing unit 140 and moves the balloon bubble along the movement path of the touch point moved by the touch & 311) (c).

After the speech balloon 311 is moved to a desired point on the image and the touch 312 is further held while the touch 313 is input, the sensing unit 140 senses the touch 313 and notifies the control unit 180 d). The controller 180 holds the additional touch 313 and inputs a drag and senses the drag through the sensing unit 140. The control unit 180 controls the coordinate of the touch point of the additional touch 313 output from the sensing unit 140 (E). The control unit 180 enlarges the speech balloon 311 based on the received coordinate information (f). Here, the control unit 180 calculates the drag distance and the direction input by the additional touch 313 using the received coordinate information. In addition, the control unit 180 determines a zoom ratio based on the calculated drag distance (the movement distance of the touch point by the additional touch input), and enlarges or reduces the zoom ratio in accordance with the calculated drag direction And determines the reduction direction.

6 is a flowchart illustrating a menu display method using a multi-touch of a mobile terminal according to an embodiment of the present invention.

First, the controller 180 displays one or more objects on the display screen (S201).

If a touch and hold is input to one of the objects displayed on the display screen, the controller 180 senses the touch input through the sensing unit 140 (S202).

When the touch and hold is detected, the controller 180 enters an object moving mode (S203). For example, when the touch is input to a predetermined object among the objects displayed on the display screen and the touch is continued for a predetermined time (2 to 3 seconds), the controller 180 enters a mode for moving the object. At this time, the controller 180 may output a beep sound indicating that the user has entered the object moving mode, or may give a visual effect to wobble the movable objects.

If the first drag is input after entering the object moving mode, the controller 180 detects the first drag through the sensing unit 140 (S204). In other words, the controller 180 detects the movement of the touch-and-hold touch point after entering the object movement mode. Here, the sensing unit 140 continuously transmits the coordinates of the touch point, which changes according to the first drag input, to the controller 180. On the other hand, if the touch and hold is released after entering the object moving mode, the controller 180 exits the object moving mode.

The control unit 180 moves the selected object through the touch and hold according to the first drag sensed (S205). For example, if the user does not release the touch after entering the object movement mode and then inputs the drag, the controller 180 moves the touched object along the movement path of the touch point through dragging.

After moving the selected object, the controller 180 detects a second drag on the selected object (S206).

Upon detecting the second drag, the controller 180 determines whether the first dragging continues (S207). That is, the controller 180 moves the touch-and-hold object and confirms whether the touch is released. The control unit 180 recognizes the multi-touch or the single touch according to whether the touch is released or not.

If the touch is maintained after the first dragging, the controller 180 displays or hides the sub-items of the selected object according to the second drag (S208). Here, the controller 180 determines whether a sub-item of the selected object exists if the first dragging continues. If there is a sub-item of the selected object, the controller 180 displays the sub-items of the selected object according to the second drag, and displays or hides the sub-items. On the other hand, if there is no sub-item of the selected object, the controller 180 may enlarge or reduce the selected object in the direction of the second drag. Alternatively, the control unit 180 may implement not to perform any operation and notify the object that there is no sub-item in the form of a sound or a message.

The controller 180 displays a sub-item of the selected object when the second drag is inputted in the direction in which the second drag moves away from the touch point held after the first drag. When the second drag is input in the direction approaching the second drag, Hide the sub-item being edited.

FIG. 7 illustrates an example of displaying a sub-item using a multi-touch in a mobile terminal according to an embodiment of the present invention.

First, the control unit 180 executes a web browser according to a user input. The control unit 180 displays the execution screen of the executed web browser on the display screen.

The control unit 180 detects the first touch 402 on the menu icon 401 displayed on the toolbar of the web browser execution screen and can move the object when the first touch 402 is maintained for a predetermined time Enters the object movement mode. Then, the controller 180 detects the first drag following the first touch 402 (a). When the touch point of the first touch 402 moves in the arrow direction as shown in FIG. 7A, the controller 180 copies and moves the menu icon 401 according to the movement of the touch point ). In a state where the first touch 402 is held, the controller 180 detects the second touch 403 on the moved menu icon 401 '.

7B, when the second drag of the second touch 403 is input following the input of the second touch 403, the controller 180 controls the operation of the second touch 403 through the sensing unit 140, The touch point movement of the second touch 403 is detected. The controller 180 displays the submenu 404 of the moved menu icon 401 'in accordance with the detected moving direction of the touch point (c). In other words, if a second drag is input in a direction in which the distance between the first touch point and the second touch point is increased, the controller 180 recognizes the sub-item as a sub-item display request and displays a sub menu of the selected menu in the drag direction do.

FIG. 8 illustrates another example of displaying a sub-item using a multi-touch in a mobile terminal according to an embodiment of the present invention.

The control unit 180 executes the memo in accordance with the control command input through the user input unit 130. [ Then, the control unit 180 inserts the data input from the user input unit 130 into the content input window of the memo execution screen.

When inserting data into the content input window, a part of the data input to the content input window is selected, the controller 180 displays a tool bar (editing tool, etc.) 411 (a). For example, when a part of the memo contents inputted in the content input window is designated as "even in the sky ", the control unit 180 displays a tool bar including at least one menu that can be performed using the block designated data.

The controller 180 detects the first touch 412 on the displayed toolbar 411 and then detects the movement of the first touch 412 to display the toolbar 411 on the first touch 412. [ (B) (c). When the second touch and drag 413 is sensed while the first touch 412 is held on the tool bar 411, the controller 180 controls the second touch and drag 413 according to the second touch and drag 413, (C) (d). Thereafter, when the user selects a desired item among the sub-items through the touch, the controller 180 performs the functions assigned to the selected item. For example, when "copy" is touched 414, the control unit 180 copies a selected part of the memo content and stores it in the memory 160. [ Then, the control unit 180 moves the cursor to the upper side to insert the copied contents according to the user input, and inserts the copied and stored contents at the position where the cursor is located when the "Paste" item is selected.

9, the control unit 180 of the mobile terminal 100 moves a specific menu selected by using the multi-touch described above to a desired position and displays the submenus 421 of the specific menu in a list.

The controller 180 detects the first touch 422 at one point on the submenu 421 displayed while displaying the submenu 421 of the specific menu. Then, the controller 180 detects the second touch 423 at another point on the submenu 421 (b).

If the detected second touch 423 moves toward the touch point of the first touch 422, the control unit 180 recognizes the sub menu as a request to hide the sub menu. Accordingly, the control unit 180 causes the submenu 421 of the specific menu displayed in the list to disappear from the display screen. At this time, the control unit 180 leaves a copy of the specific menu moved to one point on the display screen through multi-touch. When the copy is long-touched and then dragged to the point where the original of the specific menu is located, the control unit 180 causes the copy of the specific menu to disappear from the display screen.

10, when the first touch 432 and the second touch 433 are simultaneously or sequentially input on the sub-item 431 of the specific menu displayed on the display screen, Hide the sub-item 431 (a) (b). At this time, the control unit 180 causes the copy of the specific menu moved to an arbitrary point on the display screen and the sub-menu of the specific menu to disappear simultaneously on the display screen through multi-touch.
