4 is a flowchart illustrating a method of moving and displaying content by a rotational trajectory of dragging according to an embodiment of the present invention.

Referring to FIG. 4, the controller 180 displays a first area of content corresponding to a selected menu or an executed application on the display unit 151 (S410). At this time, the displayed content is a menu list including a plurality of menus, a web page, an e-book, a file list consisting of a plurality of file items, a list consisting of other communication related items, and the like. It is preferable that the content cannot be displayed. Since only a part of the content is displayed on the display unit 151, the controller 180 may display a notification symbol on the display unit 151 indicating that there is an undisplayed portion of the screen. The notification symbol may be a scroll bar or page information of a displayed page for the entire page.

On the other hand, the controller 180 receives a user command to touch and drag through the display unit 151 (S420). The user may touch the display unit 151 using a touch pointer (for example, a finger). In addition, the user may move the touch pointer while touching the display unit 151. Then, the controller 180 determines that a user command for touching and dragging is received.

The controller 180 determines whether the drag includes a rotational trajectory (S430). In detail, the controller 180 determines that the drag includes a rotational trajectory when the drag includes a trajectory that draws a curved trajectory from a specific point and the end point of the drag approaches again from the start of the drag. In addition, it may be determined that the drag includes a rotational trajectory even when the drag includes a curve trajectory having a curvature of less than or equal to the reference value with respect to the center point. It is preferable that there are two or less specific points here. Also, when the drag includes one rotational trajectory, it may be determined that the drag includes the rotational trajectory.

If it is determined that the drag includes the rotation trajectory (S430 -Y), the controller 180 moves the content in one direction corresponding to the rotation direction of the drag to display a second area of the content different from at least a portion of the first area. (S440). For example, if the rotation direction is clockwise, the controller 180 can move the content in the downward or right direction, and if the rotation direction is the counterclockwise direction, the content can also be moved in the opposite direction. On the other hand, when the last region of the content is displayed by the movement of the content, the controller 180 moves the content in one direction again from the first region of the content. And, in moving the content, the controller 180 can move the content in proportion to the moving speed of the drag or the moving distance of the drag.

As shown in FIG. 5A, the display unit 151 may display a first area 510 of a list including a plurality of items. In addition, one region of the display unit 151 may also display information about a position occupied by the entire list of a part of the currently displayed list. When the user wants to check a list that is not displayed, the user inputs a user command 520 that touches one of the areas where the list is displayed, and then draws a curve trajectory based on a specific point while dragging in a direction including a downward direction. Can be. Then, as illustrated in FIG. 5B, the controller 180 moves the list upward to display the second area 530 of the list. As the list moves upward, the display of the item displayed at the top of the display unit 151 is terminated, and a new item is displayed at the bottom of the display unit 151. In addition, when the drag includes the rotational trajectory, the controller 180 may display an indicator 535 describing a relationship between the rotational trajectory and the movement direction of the list in one region of the display unit 151.

Meanwhile, when the user continuously draws a curve trajectory with a specific point as the center point, the drag may include a semicircle shape 540 in which the end point of the drag gradually moves away from the start point of the drag and then closes to the start point of the drag. In this case, the controller 180 determines that the drag includes a rotational trajectory. As illustrated in (c) of FIG. 5, the third region 550 of the list is displayed on the display unit 151 while the list continuously moves upward. That is, if it is determined that the drag includes the rotational trajectory, the controller 180 moves the list while maintaining the moving direction to sequentially display a part of the list. In moving the list, it is preferable that the controller 180 moves the list in proportion to at least one of the moving speed and the drag moving distance of the drag.

If the last item 572 of the list is displayed on the display unit 151 while the drag is forming a rotational trajectory to rotate in one direction, as shown in FIG. The next item in item 572 marks the first item 574 in the list. Then, the list is sequentially displayed from the first item of the content in response to the drag trajectory.

In FIG. 5, when the drag starts to drag in a direction including a downward direction and receives a drag forming a rotational trajectory in a clockwise direction, the controller 180 moves the list upward and displays the list. In addition, the controller 180 may move the list upward and display the drag even when receiving a drag that starts the drag in the direction including the downward direction and forms the rotation trajectory in the counterclockwise direction. On the contrary, when the drag starts to drag in the direction including the upward direction and receives the drag forming the rotational trajectory in the clockwise or counterclockwise direction, the controller 180 can move the list downward and display the list.

In FIG. 5, the moving direction of the list is determined according to the starting direction of dragging, but is not limited thereto. The moving direction of the list may be determined according to the rotation direction of the drag. For example, if the drag direction is a clockwise direction, the controller 180 can move the list upward. If the drag direction is a counterclockwise direction, the controller 180 can move the list downward. The reverse is also possible.

In FIG. 5, the case in which the items of the list are displayed up and down has been described. However, the items of the list may be displayed left and right, and the list may be moved and displayed according to the rotational trajectory of the drag even when the list is displayed left and right. have.

6 is a reference view for explaining a method of moving and displaying content in response to a rotational trajectory of a drag according to a second embodiment of the present invention.

As shown in FIG. 6A, the display unit 151 may display a first area 610 of a list including a plurality of items. When the user wants to check a list that is not displayed, the user inputs a user command 620 that touches one of the areas where the list is displayed and then draws a curve trajectory with a specific point as a center point and drags it in a direction including a right direction. Can be. Then, as illustrated in FIG. 6B, the controller 180 moves the list to the left to display the second area 630 of the list. That is, the controller 180 ends the display of the item displayed on the left end of the display unit 151 and displays a new item on the right end of the display unit 151.

Meanwhile, when the user continuously draws a curve trajectory with a specific point as the center point, the drag may include a semicircle shape 640 in which the end point of the drag gradually moves away from the start point of the drag and then closes to the start point of the drag. In this case, the controller 180 determines that the drag includes a rotational trajectory. As shown in FIG. 6C, the moving direction of the list is maintained to the left to display the third region 650 of the list. That is, if it is determined that the drag includes the rotational trajectory, the controller 180 sequentially displays a part of the list while moving the list in one direction. In moving the list, it is preferable that the controller 180 moves the list in proportion to at least one of the moving speed and the drag moving distance of the drag.

And, as shown in (d) of FIG. 6, if the last item 672 of the list is displayed on the display unit 151 while the drag is forming a rotational trajectory to rotate in one direction, the controller 180 is the last. The next item in item 672 marks the first item 674 in the list. Then, the list is sequentially displayed from the first item of the content in response to the drag trajectory.

In FIG. 6, when the drag starts to drag in a direction including a right direction and receives a drag forming a rotational track in a clockwise direction, the controller 180 moves the list to the left and displays the list. In addition, the controller 180 may move the list to the left to display the drag even when receiving a drag that starts the drag in a direction including the right direction and forms a rotation trajectory in the counterclockwise direction. On the contrary, when the drag starts to drag in the direction including the left direction and receives the drag forming the rotational trajectory in the clockwise or counterclockwise direction, the controller 180 may move the list in the right direction and display the list.

In addition, although the moving direction of the list is determined according to the starting direction of dragging in FIG. 6, the present invention is not limited thereto. The moving direction of the list may be determined according to the rotation direction of the drag. For example, if the drag rotation direction is the clockwise direction, the controller 180 may move the list to the right direction, and if the drag rotation direction is the counterclockwise direction, the controller 180 may move the list to the left direction. The reverse is also possible.

5 and 6 illustrate a method of displaying the list according to the rotational trajectory of the drag when the list is movable in the vertical direction or the horizontal direction. Meanwhile, even when the list is movable in the vertical direction and the horizontal direction, the list may be displayed according to the rotational trajectory of the drag.

FIG. 7 is a reference view for explaining a method of moving and displaying content in response to a rotational trajectory of drag according to a third embodiment of the present invention.

As shown in FIG. 7A, the display unit 151 may display a first area 710 of a list including a plurality of items. When the user wants to check the non-displayed list, the user may form an elliptic trajectory 720 having a long axis in the horizontal direction by touching one region of the region where the list is displayed and starting dragging in a direction including a right direction.

Then, as illustrated in (b) of FIG. 7, the controller 180 may move the list to the left to display the second area 720 of the list that is at least partially different from the first area. That is, the controller 180 ends the display of the item displayed on the left end of the display unit 151 and displays a new item on the right end of the display unit 151.

In FIG. 7, when an elliptic trajectory having a long axis in a horizontal direction is formed while starting dragging in a direction including a right direction, the controller 180 moves the list to the left direction. Similarly, if an elliptic trajectory having a long axis in the horizontal direction is formed while dragging starts in a direction including the left direction, the controller 180 may move the list to the right direction.

In addition, when an elliptic trajectory having a long axis in the horizontal direction is formed while dragging starts in the clockwise direction, the controller 180 may move the list in the right direction. On the contrary, when the drag starts counterclockwise and an elliptic trajectory having a long axis in the horizontal direction is formed, the controller 180 can move the list to the left direction. Of course the reverse is also possible.

FIG. 8 is a reference view for explaining a method of moving and displaying content in response to a rotational trajectory of drag according to a fourth embodiment of the present invention.

As shown in FIG. 8A, the display unit 151 may display a first area 810 of a list composed of a plurality of items. When the user wants to check the undisplayed list, the user may form an elliptic trajectory 820 having a long axis in the vertical direction by touching one region of the region where the list is displayed and starting dragging in a direction including the downward direction.

Then, as illustrated in FIG. 8B, the controller 180 moves the list upward to display the second area 830 of the list that is at least partially different from the first area. That is, the controller 180 ends the display of the item displayed on the top of the display unit 151 and displays a new item on the bottom of the display unit 151.

In FIG. 8, when an elliptic trajectory having a long axis in the vertical direction is formed while dragging starts in a direction including a downward direction, the controller 180 moves the list upward. Similarly, if an elliptic trajectory having a long axis in the vertical direction is formed while dragging starts in a direction including the upward direction, the controller 180 may move the list downward.

In addition, if an elliptic trajectory having a long axis in the vertical direction is formed while dragging starts in the clockwise direction, the controller 180 may move the list upward. On the contrary, if an elliptic trajectory having a long axis in the vertical direction is formed while dragging is started in the counterclockwise direction, the controller 180 can move the list downward.

In this embodiment, the list moves in one direction while a dragging user command including a rotation trajectory is input. However, the present invention is not limited thereto. The list may move in one direction after the drag including the rotation trajectory is finished. The initial movement speed for the list is determined in response to the drag speed or the drag distance, and the movement speed may decrease gradually over time.

Meanwhile, the content may be displayed by moving the content according to the drag trajectory, and the content may be displayed in various ways.

9 is a flowchart illustrating a method of changing the size of content by a rotational trajectory of dragging according to an embodiment of the present invention.

Referring to FIG. 9, the controller 180 displays at least one area of content corresponding to a selected menu or an executed application on the display unit 151 (S910). In this case, the entire content may be displayed on the display unit 151, and a part of the content may be displayed.

On the other hand, the controller 180 receives a user command to touch and drag through the display unit 151 (S920). The user may touch the display unit 151 using a touch pointer (for example, a finger). In addition, the user may move the touch pointer while touching the display unit 151. Then, the controller 180 determines that a user command for touching and dragging is received.

The controller 180 determines whether the drag includes a rotational trajectory (S930). In detail, the controller 180 determines that the drag includes a rotational trajectory when the drag includes a trajectory that draws a curved trajectory from a specific point and the end point of the drag approaches again from the start of the drag. In addition, it may be determined that the drag includes a rotational trajectory even when the drag includes a curve trajectory having a curvature of less than or equal to the reference value with respect to the center point.

If it is determined that the drag includes the rotation trajectory (S930-Y), the controller 180 changes the size of the content corresponding to the rotational direction of the drag and displays it (S940). For example, if the rotation direction is clockwise, the controller 180 can enlarge and display the content. If the rotation direction is counterclockwise, the controller 180 can reduce and display the content. On the other hand, when the size of the content is changed, the controller 180 may change the size of the content in proportion to the moving speed of the drag, the moving distance of the drag, and the like.

FIG. 10 is a reference view illustrating a method of changing and displaying a size of content in response to a rotational trajectory of drag according to a first embodiment of the present invention.

As shown in FIG. 10A, the display unit 151 displays an image 1010 which is a kind of content. The user may form a rotation trajectory 1020 that rotates in a clockwise direction after touching the display unit 151. Then, the controller 180 enlarges the size of the content in proportion to at least one of the moving speed and the moving distance of the drag. As shown in FIG. 10B, the enlarged content 1030 is displayed on the display unit 151. When displaying enlarged content, the controller 180 preferably displays an area of the content in the rotation trajectory in the center of the display unit 151.

FIG. 11 is a reference view illustrating a method of changing and displaying a size of content in response to a rotational trajectory of drag according to a second embodiment of the present invention.

As shown in FIG. 11A, the content 1110 is displayed on the display unit 151. The user may form a rotation trajectory 1120 that rotates counterclockwise after touching the display unit 151. Then, the controller 180 reduces the size of the content in proportion to at least one of the moving speed and the moving distance of the drag. As illustrated in FIG. 11B, the reduced content 1130 is displayed on the display unit 151. When displaying the reduced content, the controller 180 preferably displays an area of the content in the rotation trajectory in the center of the display unit 151.

12 is a flowchart illustrating a method of displaying sub content of content in response to a rotational trajectory of drag according to an embodiment of the present invention.

Referring to FIG. 12, the controller 180 displays at least one area of content corresponding to a selected menu or an executed application on the display unit 151 (S1210). In this case, the displayed content preferably includes a plurality of sub contents.

On the other hand, the controller 180 receives a user command to touch and drag through the display unit 151 (S1220). The user may touch the display unit 151 using a touch pointer (for example, a finger). In addition, the user may move the touch pointer while touching the display unit 151. Then, the controller 180 determines that a user command for touching and dragging is received.

The controller 180 determines whether the drag includes a rotational trajectory (S1230). In detail, the controller 180 determines that the drag includes a rotational trajectory when the drag includes a trajectory that draws a curved trajectory from a specific point and the end point of the drag approaches again from the start of the drag. In addition, it may be determined that the drag includes a rotational trajectory even when the drag includes a curve trajectory having a curvature of less than or equal to the reference value with respect to the center point.

If it is determined that the drag includes the rotational trajectory (S1230-Y), the controller 180 displays a plurality of sub-contents in a superimposed manner in response to the rotational direction of the drag (S1240). For example, if the rotation direction is clockwise, the controller 180 displays the first sub content among the sub contents, and the remaining sub contents are sequentially displayed in the right direction. If the rotation direction is counterclockwise, the controller 180 displays the first sub content among the sub contents, and the remaining sub contents are sequentially displayed in the left direction.

Meanwhile, if the portable terminal of the present invention is a terminal capable of displaying a 3D stereoscopic image, the controller 180 may sequentially display stereoscopic depths of sub-contents.

FIG. 13 is a reference view for explaining a method of displaying sub content in response to a rotational trajectory of a drag according to an embodiment of the present invention. FIG.

As shown in FIG. 13A, a title 1310 of a content is displayed on the display unit 151. The user may form a rotation trajectory 1320 that rotates in a clockwise direction after touching the display unit 151. Then, as illustrated in FIG. 13B, the controller 180 displays the plurality of sub contents 1330 sequentially stacked in proportion to at least one of the moving speed and the moving distance of the drag. In addition, in FIG. 13B, after the user touches the display unit 151, the rotation trajectory 1340 may be formed to rotate counterclockwise. Then, the controller 180 may overlap the frontmost sub-content 1332 of the plurality of sub-contents each time the drag is rotated one by one, so as to overlap the rearmost of the plurality of sub-contents as illustrated in (c) of FIG. 13. You can also place it.

Meanwhile, the present invention can be embodied as processor readable codes on a processor readable recording medium provided in a mobile terminal such as a mobile station modem (MSM). The processor-readable recording medium includes all kinds of recording devices that store data that can be read by the processor. Examples of the processor-readable recording medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, and the like, and may be implemented in the form of a carrier wave such as transmission through the Internet. The processor-readable recording medium can also be distributed over network coupled computer systems so that the processor-readable code is stored and executed in a distributed fashion.
