The motion sensor 120 performs a role of receiving a user's operation performed on the mobile terminal. As the motion sensor unit 120 according to an embodiment of the present invention, an ultrasonic sensor, an acceleration sensor, a camera sensor, and a gyro sensor may be used. As the gyro sensor, an optical gyro sensor, a mechanical gyro sensor, or the like may be used, and any sensor capable of recognizing a user's motion with rotation may be used in the present invention. In particular, the motion sensor 120 in the present invention is used to detect the movement of the mobile terminal to rotate. For example, when the mobile terminal rotates in a left direction or a right direction based on a predetermined axis, the motion sensor 120 detects a rotation operation of the mobile terminal, generates a sensor signal, and transmits the generated sensor signal to the controller 160. The sensor signal includes raw data relating to the position and rotation variation of the portable terminal.

The storage unit 130 stores a program and data necessary for the operation of the portable terminal, and may be divided into a program area and a data area. The storage unit 130 according to an exemplary embodiment of the present invention stores data about graphic objects displayed on the display unit 144. The data for the graphic object includes image data corresponding to each of the rotation angles. The storage unit 130 also stores an application program for displaying the rotated image of the graphic object. The controller 160 receives the input of the motion sensor 120 using the application program and displays the rotated image of the graphic object on the display unit 144.

The touch screen unit 140 includes a touch sensor 142 and a display unit 144. The touch sensor 142 detects whether the touch device is in contact with the touch screen. The touch mechanism may correspond to a user's hand or a touch pen. The touch sensor 142 may be configured as a capacitive touch sensing sensor, or may be configured as a pressure sensor, and not limited thereto. Any type of sensor capable of detecting the approach of an object may be used. The touch sensor 142 may be formed on one side or one side of the portable terminal, and serves as an input unit of the portable terminal. The touch sensor 142 detects a touch of the touch device on the touch screen and transmits a touch detection signal to the controller 160. The touch detection signal may include whether a touch of the touch mechanism is sensed and touch position information (horizontal position information) of the touch mechanism. According to an exemplary embodiment of the present invention, when a user touches a graphic object displayed on the display unit 144, the touch sensor 142 transmits coordinate data regarding the touched position to the controller 160, and the controller 160 is touched. The graphic object displayed at the location may be recognized and a corresponding function may be performed.

The display unit 144 may be formed of a liquid crystal display (LCD), and visually provides a menu, input data, function setting information, and various other information of the portable terminal to the user. For example, the display unit 144 performs a function of outputting a mobile terminal boot screen, a standby screen, a display screen, a call screen, and other application execution screens. The display unit 144 according to an exemplary embodiment of the present invention displays a graphic object stored in the storage unit 130 by a command of the controller 160. In addition, the display unit 144 serves to display a rotated image of the graphic object by a command of the controller 160. The display unit 144 may include a control device for controlling the liquid crystal display, a video memory capable of storing image data, and elements of the liquid crystal display.

The key input unit 150 receives a key manipulation signal of a user for controlling the portable terminal and transmits the same to the controller 160. The key input unit 150 may be configured as a keypad including a numeric key and a direction key, and may be formed of only a predetermined function key on one side of the portable terminal. According to the exemplary embodiment of the present invention, the key input unit 150 may be omitted in the case of a portable terminal which can be operated by only the touch sensor 142.

The controller 160 controls the overall operation of the portable terminal and the signal flow between the internal blocks of the portable terminal. When the control unit 160 receives a sensor signal including raw data from the motion sensor 120, the controller 160 analyzes the sensor signal and extracts at least one parameter. The extracted parameter may include a rotation direction and a rotation angle. The controller 160 determines the shape of the graphic object displayed on the display unit 144 based on the extracted parameter. In particular, in the present invention, the graphic object is displayed in a rotated form, and the controller 160 analyzes the extracted parameters to determine the rotation direction and the rotation angle of the graphic object, so that the display unit 144 outputs the rotated image. To control. When the controller 160 outputs the rotated image to the display unit 144, the controller 160 may use an application program that changes and displays the graphic object.

The controller 160 may control the display unit 144 to change and display the 2D graphic object as a 3D graphic object. The controller 160 according to an embodiment of the present invention plays a role of determining a graphic object to be displayed as the rotated image. In general, a plurality of graphic objects are displayed on the display unit 144, and the controller 160 determines a graphic object requiring display of a rotated image among the displayed graphic objects, and displays only the graphic object in a rotated form. The display unit 144 may be controlled. The controller 160 may control the display unit 144 to display an image in which the graphic object is rotated in a direction opposite to or in the same direction as the rotation direction of the mobile terminal.

2 is a flowchart illustrating a graphic display method according to an exemplary embodiment of the present invention.

In operation 210, the controller 160 receives an instruction of a user and executes an application. The application according to the embodiment of the present invention may correspond to all application programs executed in the portable terminal. In general, the application may include an application for performing a specific function installed in the mobile terminal, such as a music playback program, a video playback program, even if the background screen display function, display screen off function, menu screen display function corresponding to the application of the present invention. can do. In particular, in the present invention, a function defined to recognize an operation input may correspond to an application.

In step 220, the controller 160 controls the display unit 144 to output a screen on which the application is executed. For example, when a moving picture reproducing program is executed, the display unit 144 displays a moving picture reproducing window, a moving picture reproducing operation menu, contents to be reproduced, and the like. When the application of the menu screen display function is executed, the display unit 144 displays icons for executing a function included in the menu screen. When the application of the background display function is executed, the display unit 144 displays a background screen set by the user or basically set in the portable terminal. A plurality of graphic objects (eg, an antenna image, a battery image, a visual information image, etc.) may be displayed on the background screen, and the background screen itself may be one graphic object according to a setting.

In step 230, the controller 160 determines whether an operation of rotating the mobile terminal is input. When the user rotates the portable terminal about an axis set in the portable terminal or a set reference point, the motion sensor 120 detects that the portable terminal is rotated. The motion sensor 120 detects a rotational motion of the portable terminal and generates a sensor signal. The sensor signal includes raw data relating to a position change amount or a rotation change amount of the portable terminal.

In step 240, the controller 160 receives the sensor signal from the motion sensor 160, analyzes the sensor signal, and extracts a parameter for the input operation. The parameter according to the embodiment of the present invention may include a rotation direction and a rotation angle. The rotation direction and the rotation angle of the portable terminal are specifically disclosed in FIG. 3.

In FIG. 3, reference numeral 310 illustrates an X, Y, and Z axis around a reference point set in the portable terminal and the portable terminal. Reference numeral 310 is shown to be set in the center of the portable terminal, but is not limited thereto, the reference point may be located at all points of the portable terminal according to the setting.

Reference numeral 320 in FIG. 3 illustrates a portable terminal and X, Y, and Z axes when the portable terminal moves to the left with respect to the Y axis. Reference numeral 320 shows a form in which the mobile terminal is moved to the left by the angle θ about the Y axis. Θ is calculated using the angle between Z and Z 'and the angle between X and X'. The controller 160 extracts parameters for the rotation direction and the rotation angle based on the data shifted θ to the left based on the Y axis. As the data for extracting the parameter, the rotation angle of each axis may be used, such as X (0), Y (θ), and Z (0), or a change in coordinate value in three-dimensional coordinates may be used. For example, when the coordinate of the point indicated by reference numeral 310 is set to (x1, y1, z1), and moved to the left at reference numeral 320 and changed to (x2, y2, z2), the rotation direction is changed to the changed coordinate value. And the angle of rotation can be determined.

In addition, the controller 160 may determine the rotation direction and the rotation angle according to a reference value for determining whether there is a change. For example, when a reference value for determining whether there is a change is set to 0.1 °, when the change amount is 0.1 ° or more, the controller 160 determines that the command changes the graphic and displays it. When the reference value for determining whether there is a change is set to 1 °, the control unit 160 determines that the graphic is changed and displayed only when the angle is changed by 1 ° or more. In this case, the control unit 160 may be more sensitive to the case of setting 0.1 ° than setting 1 °. Even when the parameter is determined by the coordinate value, the sensitivity can be adjusted by setting the minimum unit of the change value of the coordinate.

In FIG. 3, the portable terminal is rotated with respect to the Y axis, but may be rotated up and down with respect to the X axis, and may be rotated in the lateral direction of the portable terminal with respect to the Z axis. In addition, the parameter can be extracted by combining a plurality of axes among the X-axis, Y-axis, and Z-axis. That is, the rotation direction and the rotation angle are determined by combining data of how much the angle has moved with respect to each axis.

In step 250, the controller 160 determines a graphic object requiring display change. The graphic object is an image displayed on the display unit 144 and corresponds to a graphic unit individually recognized by the controller 160. The graphic object may be each of a single detachable graphic, and the set of the single detachable graphic may be one graphic object according to a setting. The controller 160 determines a graphic object requiring display change among at least one graphic object displayed on the display unit 144. Data relating to a graphic object requiring display change is stored in the storage unit 130, and a user may set a graphic object requiring display change. Alternatively, a graphic object requiring display change for each application program may be set and stored in the storage 130. Graphic objects requiring display changes are shown in FIG. 4. Reference numeral 410 of FIG. 4 denotes a menu screen displaying an icon of a two-dimensional rectangle. The antenna display at the top left of the display unit 144 and the battery display and the visual information display at the top right may be respective graphic objects according to settings, and the graphic objects correspond to the entire background screen, and the antenna display, the battery display, The visual information display may correspond to some elements constituting the background screen. Also, the 'camera', 'music', 'radio' and 'photo' icons can be graphic objects, and the desktop displayed in the background can also be graphic objects.

In this case, it is assumed that graphic objects requiring display change are set to 'camera', 'music', 'radio' and 'photo' icons with dotted lines. In reference numeral 520 of FIG. 5, an antenna display, a battery display, a visual information display, a 'movie player' window, and a background image correspond to graphic objects, and graphic objects requiring display change are set to a 'movie player' window indicated by dotted lines. Assume that In reference numeral 530 of FIG. 5, an antenna display, a battery display, a visual information display, a three-dimensional graphic in the form of a hexahedron, and a background image correspond to the graphic object, and the three-dimensional graphic in the form of a hexahedron is set to a graphic object requiring display change. Assume In step 250, the controller 160 determines that the above-mentioned 'camera', 'music', 'radio', 'photo' icon, 'movie player' window, and three-dimensional graphics in the form of a cube are graphic objects requiring display change. do.

The controller 160 changes and displays the graphic object requiring the display change according to the extracted parameter in step 260. The controller 160 analyzes a sensor signal transmitted from the motion sensor 120 in step 240 and extracts a parameter including a rotation direction and a rotation angle. The extracted parameter is referenced to change and display a graphic object. The graphic object is changed and displayed as a rotated image, and the degree of rotation depends on the extracted parameters. The controller 160 according to an exemplary embodiment of the present invention may control the display unit 144 to rotate and display the graphic object in a direction opposite to the direction in which the portable terminal is rotated. According to an exemplary embodiment of the present invention, the controller 160 may control the display unit 144 to rotate and display the graphic in the same direction as the direction in which the portable terminal is rotated. According to an exemplary embodiment of the present invention, the controller 160 may control the display unit 144 to rotate and display the same angle as the angle at which the portable terminal is rotated.

Rotated images of graphic objects are stored for each rotation angle. In case of storing the rotated image by the narrow rotation angle, it can provide immediate feedback to the user rather than storing the rotated image by the wide rotation angle. In addition, in the present invention, the controller 160 may control the display unit 144 to rotate and display the graphic object only by the set threshold angle. When the rotated image of the graphic object is stored only within a range below the set threshold angle, the display unit 144 may not display the rotated image above the set threshold angle. For example, if the rotated image of a graphic object is set only from 0 ° to 20 °, the graphic object is no longer displayed when the mobile device is rotated further while the graphic object is displayed as a 20 ° rotated image. It doesn't work. This is because when the mobile terminal rotates more than a certain angle, the user cannot recognize the graphic. In this case, since the graphic object does not need to be rotated and displayed, the setting of the threshold angle can reduce the rotated image capacity. It makes sense.

5 is a diagram illustrating a screen in which two-dimensional graphics are changed and displayed according to an exemplary embodiment of the present invention.

Reference numeral 510 of FIG. 5 is a diagram illustrating a screen displaying an icon in an initial state. The display screen shows the antenna display at the top left, the battery display and time information display at the top right, and the 'camera', 'music', 'radio' and 'photo' icons. When the mobile terminal executes an application and displays an execution screen, the portable terminal displays a basic image of the graphic object as an initial state. The basic image of the graphic object corresponds to an image displayed by the display unit 144 when a rotation operation is not applied to the mobile terminal. Thereafter, the motion sensor determines whether the motion of rotating the mobile terminal occurs, detects the rotation of the mobile terminal, and rotates and displays the icons according to the degree of rotation. Graphic objects that require display changes are set to the 'camera', 'music', 'radio', and 'photo' icons.

Reference numeral 520 denotes a screen moved to the right with respect to the Y axis illustrated in FIG. 3. At this time, the antenna display, the battery display and the visual information display, which are graphic objects for which display change is not required, are not changed.

Indicates. The rotated image corresponds to a 3D graphic, and the controller 160 controls the display unit 144 to change from the 2D graphic object to the 3D graphic object. The angle rotated by the graphic object may correspond to the angle rotated by the mobile terminal, or may correspond to a rotation angle set for each rotation angle of the mobile terminal. In addition, only some of the icons of the 'camera', 'music', 'radio', and 'photo' icons may be rotated and displayed according to the setting method of the graphic object requiring display change.

6 is a diagram illustrating a screen in which two-dimensional graphics are changed and displayed according to another exemplary embodiment of the present invention.

A display screen illustrated at 610 of FIG. 6 is the same as 510 of FIG. 5. In the state where the graphic objects are displayed, an operation of rotating around the Z axis of FIG. 3 is input.

Reference numeral 620 of FIG. 6 denotes a screen displayed on the display unit 144 when the portable terminal is rotated at a predetermined angle with respect to the Z axis. Antenna display, battery display and visual information display that are not set to graphic objects requiring display change are not changed. On the other hand, the 'camera', 'music', 'radio' and 'photo' icons are displayed with the image tilted to the right with respect to the center of each icon. When the user rotates the mobile terminal to the left about the Z axis, the icons are rotated to the right in real time. The icons shown at 610 correspond to two-dimensional graphics, and the icons shown at 620 also correspond to two-dimensional graphics. In this embodiment, the graphic dimension is not changed.

7 is a diagram illustrating a screen in which two-dimensional graphics are changed and displayed according to another exemplary embodiment of the present invention.

Reference numeral 710 of FIG. 7 denotes a screen on which a 'movie player' application is executed. Like reference numeral 510 of FIG. 5, reference numeral 710 also displays an antenna display, a battery display, a time information display, and a 'movie player window'. Graphic objects that require display changes are set to the 'movie player window'. When the user moves the portable terminal to the right with respect to the Y axis, the screen shown by reference numeral 720 is displayed on the display unit 144. The antenna display, battery display and visual information display are not changed, but the 'movie player' window displays an image rotated to the left about the Y axis. The 'movie player' window displayed at 720 is a 3D graphic. The controller 160 controls the display unit 144 to convert the two-dimensional graphic object indicated by reference numeral 710 into a three-dimensional graphic object indicated by reference numeral 720. When the graphic object is set to the entire display screen, the display unit 144 displays a three-dimensional image in which the entire display screen is rotated to the left about the Y axis. Alternatively, when only the content playback portion is displayed as a graphic object requiring display change in the 'movie player' window, the display unit 144 displays only the content playback portion as a 3D image rotated to the right about the Y axis.
