The input unit 130 is a user interface for receiving various commands from a user, and the implementation thereof is not particularly limited. For example, the input unit 130 may be implemented as a key pad, a dome switch, a touch pad (constant voltage / capacitance), a jog wheel, a jog switch, and the like.

The input unit 130 may include a plurality of operation units (see 131 and 132 of FIG. 2) for receiving a command for controlling an operation of the mobile terminal 100. The manipulation units may be employed in any manner as long as the user is in a tactile manner to operate while having a tactile feeling. The contents input by the manipulation units 131 and 132 may be variously set. For example, the first manipulation unit 131 receives a command such as start, end, scroll, and the like, and the second manipulation unit 132 adjusts the volume of sound output from the receiver or the touch recognition mode of the display module 151. It may receive a command such as switching to.

In addition, in recent years, a large number of touch screen systems have been adopted due to an increase in space utilization, a demand for enlargement of a display screen, and design considerations. In this case, the input unit 130 may include the display module 151 of the mobile terminal 100. It may also be located on the entire surface of the display screen by being combined with.

The sensing unit 140 detects a current state of the mobile terminal 100 such as an open / closed state of the mobile terminal 100, a location of the mobile terminal 100, presence or absence of a user contact, orientation of the mobile terminal, acceleration / deceleration of the mobile terminal, and the like.

When the mobile terminal 100 is in a video call mode or a photographing mode, the mobile terminal 100 may display a photographed and / or received image, a UI, or a GUI.

There may be two or more displays according to the implementation form of the mobile terminal 100. In addition, as described above, when the display module 151 and a sensor for detecting a touch operation (hereinafter, referred to as a “touch sensor”) form a mutual layer structure (hereinafter, referred to as a “touch screen”), the display module 151 may also be used as an input device in addition to the output device. The touch sensor may have, for example, a form of a touch film, a touch sheet, a touch pad, or the like.

Although the configuration of a general mobile terminal has been described above, hereinafter, components related to the method of rotating display information using a multi-touch according to an embodiment of the present invention will be described in detail.

3 is a flowchart illustrating a method of rotating display information using multi-touch according to an embodiment of the present invention, and FIGS. 4A and 4B are diagrams illustrating an application example of the method of rotating display information of FIG. 3.

Referring to FIG. 3, in the display information rotating method using the multi-touch according to an embodiment of the present invention, a first touch by a user is input on the touch screen [S110], and the contact state by the first touch is determined. When the second touch having the directionality is input by the user in the maintained situation [S120], the controller 180 rotates the displayed information through the display screen of the touch screen based on the directionality of the second touch. All. Here, the state in which the touch is maintained means a state in which the contact is maintained without removing the hand from the touch screen.

In FIG. 3, it is assumed that a configuration for receiving a touch input and a configuration for displaying specific information are implemented through a single integrated touch screen (hereinafter, as described above), but receiving the first touch and the second touch. It is apparent that the configuration for the touch input device (ie, the touch input device) may be located at a position separate from the display of the terminal.

4A and 4B, an application example according to the flowchart of FIG. 3 may be described below. 4A and 4B assume a " multi-touch case " in which a second touch having directivity is made in a situation where the contact position where the first touch is fixed on the touch screen is maintained as it is.

4A and 4B also assume that a map related to "map search application service" is displayed on the display screen of the terminal. In addition, for convenience of description, it is assumed that the first touch is made by the user's thumb and the second touch is made by the user's index finger.

As shown in FIG. 4A, when the thumb touches the first position CP1 on the map displayed on the display screen with a thumb, the index finger touches the second position CP2, the controller 180 controls the first position. And recognize that the multi-touch according to the second position is performed.

In the above state, when the user moves the contact position from the second position (CP2) to the third position (CP3) while maintaining the touch by the index finger, the control unit 180 as described above Recognizing a change in the contact position by the touch, and correspondingly rotates the map displayed on the display screen based on the directionality of the second touch. This can be easily confirmed through a change in the position of a specific POI on the map shown in FIG. 4B.

Referring to FIG. 4B, it can be seen that the specific POI displayed at the Q1 position in FIG. 4A is changed to the Q2 position through the touch rotation operation by the second touch as described above.

The following method may be used to rotate the display information as described above.

For example, when a second touch having directivity is input while the contact position of the thumb by the first touch is fixed, the controller 180 sets the contact position by the first touch as the rotation center point. The information displayed on the display screen can be rotated. For example, in the case of FIGS. 4A and 4B, the entire map displayed on the screen is rotated in the clockwise direction with CP1 as the rotation center point.

In this case, the rotation direction is determined according to the direction of the second touch. For example, in FIG. 4A, since the second touch is based on a movement trajectory according to L2 or a movement trajectory according to L1, both L1 and L2 have a direction related to a clockwise direction. Regardless of the difference in the movement trajectory, it can be made clockwise (see FIG. 4B).

In addition, the second touch having the directivity may be based on various touch operations. For example, the second touch may be made by a touch operation (eg, a drag operation) having successive movement trajectories on the touch screen, and the contact holding time may be a predetermined time (eg, 1 Or an intermittent touch operation (eg, a flicking operation) that is less than or equal to seconds.

For example, when the second touch is performed by a touch operation such as the drag operation, the controller 180 calculates a movement amount according to the movement trajectory of the second touch and corresponds to the calculated movement amount on the screen. The displayed display information can be rotated.

As another example, when the second touch is performed by a touch operation such as the flicking operation, the controller 180 may preset display information displayed on the screen every time a second touch by the intermittent touch operation occurs. It may be rotated by the entire amount (for example, 5 degrees).

Of course, when a touch operation (for example, a sliding operation) in which the drag motion and the flicking motion are mixed is input, a rotation method in which the two methods described above are mixed may be employed.

The controller 180 may calculate a value of at least one of touch intensity (ie, pressure) and speed (ie, speed) of the second touch, and linearly change the rotation amount of the display information in proportion thereto. You can also For example, the greater the touch intensity or the faster the touch speed, the greater the amount of rotation.

4A and 4B have been described on the assumption that the entire map screen associated with the map search application is rotated. However, various display information rotation methods may be provided.

For example, when any one of a plurality of information items displayed on the display screen is specified by the first touch, the information specified by the first touch when the second touch having the directionality is input Only items may be rotated. This will be easily understood through FIG. 6 to be described later.

As another example, the controller 180 may rotate the application screen itself displayed at a position corresponding to the contact position of the first touch, based on the second touch having the directionality. For example, the e-mail input window displayed on the screen may be rotated vertically or horizontally.

In the above description, the rotation amount is determined based on the movement amount, the intensity, the speed, and the like of the second touch, but the rotation amount is a fixed value each time an event by the second touch occurs. For example, it may be determined by 90 degrees).

3 to 4B have described the multi-touch case in which a second touch having directivity is made while the first touch is fixed. Hereinafter, the multi-touch case in which the contact position of the first touch is also changed will be described with reference to FIGS. 5 to 7.

5 is a flowchart illustrating a method of rotating display information using multi-touch according to another embodiment of the present invention, and FIGS. 6 and 7 are diagrams showing examples of application of the method of rotating display information of FIG. 5.

Referring to FIG. 5, in the display information rotating method using the multi-touch according to another embodiment of the present invention, as the first touch and the second touch are input on the touch screen [S210], a predetermined information area on the display screen is provided. Is specified [S220], and in the state where the multi-touch as described above is maintained, when the position change occurs at both the contact positions of the first and second touches, the controller 180 is based on the direction of the change of the contact position. By rotating the specified information area.

For example, referring to FIG. 6, in a state in which the multi-touch by the first touch and the second touch is maintained (see CP5 and CP6 of FIG. 6A), the contact position by the first touch is shown. And a change in position occurs at both the contact positions caused by the second touch (see CP7 and CP8 in FIG. 6B), and the change of each touch position according to the first touch and the second touch is clockwise. Has directionality.

In this case, the controller 180 specifies the information area 20 specified according to each initial contact position according to the first touch and the second touch, and then the specified information area 20 is determined. It rotates corresponding to the change amount of each contact position according to a 1st touch and a said 2nd touch (refer OP and NP comparison of FIG. 6 (b)).

In this case, the information area may be specified as, for example, a rectangular area having a diagonal line at each contact position by the first touch and the second touch.

As another example, referring to FIG. 7, while the multi-touch by the first touch and the second touch is maintained (see CP5 and CP6 of FIG. 7), the contact position and the second touch by the first touch are maintained. The position change occurs in all the contact positions by touch (refer to CP9 and CP10 in FIG. 7), and the change in each contact position according to the first touch and the second touch has clockwise directionality.

In this case, the controller 180 determines the information area 20 specified according to each initial contact position according to the first touch and the second touch, based on the direction of the first touch and the second touch. In addition, the size of the information area can be proportionally enlarged (see NP2 of FIG. 7) or reduced in correspondence with the amount of change in each contact position according to the first touch and the second touch.

Although the above has been described with reference to embodiments of the present invention, those skilled in the art may variously modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. And can be changed easily.
