[0001] The present invention relates to a three-dimensional function key display method for a portable terminal and a portable terminal having a three-dimensional function key,

And relates to a graphical user interface (GUI) technique of a portable terminal.

A graphical user interface (GUI) is a work environment in which a user interacts with a computer through graphics. The user interface so far has been made through an input device such as a keyboard or a mouse. Typically, the user selects one of the menus of the screen using a keyboard, a mouse, or the like to instruct the work.

In recent years, as a touch screen has been developed, a graphical user interface in which a user directly touches a screen without a separate input device has appeared. For example, in the case of a smartphone, various graphic icons are displayed on the touch screen, and the user performs an interaction with the system by touching a graphic icon displayed on the touch screen.

In addition, several functions may be mapped to one graphic icon. For example, in a keypad for making a telephone call, when the number '1' is short-pressed, an original function for inputting a telephone number is performed. However, if the user presses and holds the key for a long time, As shown in FIG.

However, it is difficult for the user to memorize which functions are mapped to any one of the graphic icons, and it is inconvenient to directly execute corresponding functions in order to check them.

In the case of the existing GUI button, there was a limitation of the area to display the contents inputted when the button was pressed, and it was difficult and aesthetic deterioration for the user to recognize when the button was displayed in duplicate.

Also, in order to change the mode of the contents input by the GUI button, it is necessary to press the mode changing button or access the menu to change the mode.

However, if different information or characters are mapped on each side of the three-dimensional function key, and the other side is provided by rotating the three-dimensional function key according to the user's intuitive operation by recognizing the user's operation, Can be displayed, and it is possible to reduce the inconvenience of having to perform a long tab for input.

Hereinafter, specific examples for carrying out the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 illustrates a configuration of a portable terminal having a three-dimensional function key according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the portable terminal 100 according to the present embodiment may be a mobile phone, a smart phone, a tablet PC, a PMP, or an MP3 player. The portable terminal 100 may include an operation detecting unit 101, a display unit 102, and a control unit 103. [ In addition, it may further include a storage unit 104.

The operation detecting unit 101 detects the operation of the user regarding the portable terminal. For example, the operation detecting unit 101 may detect a tilt operation or a flip operation. The tilting operation refers to an operation in which the user tilts the portable terminal 100. The tilting operation can be detected when the user tilts the portable terminal 100 in a specific direction and angle with respect to the virtual axis. The flip operation is an operation in which the user instantaneously jumps the portable terminal 100. When the user shakes the portable terminal 100 in a specific direction such as front, back, left, right, up and down, a flip operation can be detected. In addition to the tilting operation and the flip operation, the operation detecting unit 101 can detect the operation of various users applied to the mobile terminal 100. For example, the motion detection unit 101 may detect that the user shakes the portable terminal 100 or applies a pressure equal to or higher than a predetermined reference value to the portable terminal 100. [

In order to detect the user's motion, the motion detection unit 101 may include various sensors and analysis modules for analyzing the values of the sensors. As the sensor, an acceleration sensor, a gyro sensor, a camera, a temperature sensor, a pressure sensor, an illuminance sensor, a proximity sensor, and an ultrasonic sensor may be used, and the type of the sensor is not particularly limited.

The display unit 102 displays a three-dimensional function key. The three-dimensional function key is used to control various functions of the portable terminal 100. The three-dimensional function key is a three-dimensional dial for inputting a number (i.e., telephone number) Dimensional keypad. ≪ / RTI > Also, the three-dimensional function key is a graphical image expressed in three dimensions and can have at least two surfaces. As an example, the shortcut number information corresponding to the keypad number may be mapped to the keypad number on the first side of the three-dimensional function key. The abbreviated number information may be identification information (e.g., name, icon, avatar, etc.) of the contactee corresponding to the keypad number. As another example, the main button group may be mapped to the first face of the three-dimensional function key, and the sub-button group may be mapped to the second face. The main button group may include Hangul characters, and the sub button group may include alphabets, special characters, numbers, and the like. Here, for the sake of clarity, we have explained that the three-dimensional function key has two sides. However, this is merely an example, and it is needless to say that the three-dimensional function key may be formed of a polyhedron having three or more faces.

According to a further aspect, each identification information of each abbreviated number information can be displayed on each side of the three-dimensional function key. For example, a keypad number is displayed on the first surface of the three-dimensional function key, a name of the abbreviated number corresponding to the number is displayed on the second surface, a telephone number of the abbreviated number corresponding to the number is displayed on the third surface, On the four sides, a photograph or the like corresponding to the abbreviated number corresponding to the number may be displayed. On the other hand, if the number of the abbreviated numbers is larger than the number of the keypad numbers, the abbreviated numbers may be mapped on each surface of the three-dimensional function key. For example, if the numeric keypad numbers 0 to 9 are displayed on the three-dimensional function key and 0 to 29 are stored, the numeric keypad number is assigned to the first side of the three-dimensional function key, and the numeric keypad numbers 0 to 9 The identification information of the abbreviated numbers 10 to 19 on the third surface and the identification information of the abbreviated numbers 20 to 29 on the fourth surface.

According to yet another additional aspect, different sides of the three-dimensional function key may display different mapping groups. For example, a Korean character may be displayed on the first face of the three-dimensional function key, an English character may be displayed on the second face, and a special character or a number may be displayed on the third face.

The display unit 101 may be a touch screen. Accordingly, the user can use various functions of the portable terminal 100 by touching the three-dimensional function key displayed on the display unit 101. [

The display unit 101 can display the three-dimensional function key three-dimensionally. For example, the display unit 101 may give a predetermined graphic effect so that the three-dimensional function key is perceived as rotating.

The control unit 103 controls the display switching of the three-dimensional function key displayed on the display unit 101 according to the operation of the user detected by the operation detecting unit 101. [ For example, the control unit 103 controls the three-dimensional function key to display a portion of the first surface and the second surface at the same time or switch to the second surface, It is possible to control the graphic effect of the unit 101. [ Here, the rotation of the three-dimensional function key refers to the rotation of the front surface of the three-dimensional function key with respect to the virtual center axis of the three-dimensional function key to the rear side, the rear side to be displayed forward (front-rear direction) (Left and right direction), and a part of the three-dimensional function key is folded on the basis of a virtual center axis (for example, the horizontal axis), and the rear portion thereof is displayed.

For example, when the tilt operation is detected by the motion detection unit 101, the control unit 103 switches the display of the first surface to the display of the second surface while rotating the three-dimensional function key according to the tilt direction and angle . At this time, by controlling the display switching so that the rotation angle of the three-dimensional function key becomes substantially equal to the detected tilt angle, it is possible to intuitively perform switching and recognition of the display on the first surface and the display on the second surface . For example, when the portable terminal 100 is inclined at a certain angle to the backward direction, the three-dimensional function key is rotated at the same angle as the inclined angle of the portable terminal 100 so that a part of the first surface and a part of the second surface are simultaneously displayed . When the mobile terminal is further tilted toward the backward direction, the first surface may completely disappear while moving backward, and the second surface may be displayed as being displayed forward. Similarly, it is possible to display the first face which has passed backward through the forward tilting operation of the portable terminal 100 while moving forward.

On the other hand, in addition to rotating the three-dimensional function key in conjunction with the tilt direction and angle of the mobile terminal 100, the control unit 103 may display the three-dimensional function key by rotating the tilting angle . That is, when the mobile terminal is tilted in the forward and backward directions, the three-dimensional function key is rotated in the forward and backward directions by an inclined angle, and when the mobile terminal is tilted in the leftward and rightward direction, It can also be rotated and displayed.

According to a further aspect related to the tilting operation, it is also possible to maintain the display of the first surface up to a predetermined critical angle range when tilting the portable terminal 100, and switch the display to the second surface when the threshold angle range is exceeded. At this time, when the display on the second surface is switched, it is preferable that the display on the second surface is maintained even if the portable terminal 100 is returned to the original horizontal state. In other words, it is possible to return to the first surface again when there is a tilt exceeding the upper critical angle range while the second surface is being displayed.

As another example, when the flip operation is detected by the operation detection unit 101, the control unit 103 reverses the three-dimensional function key every time there is a flip operation, and displays the display on the first face as the display on the second face, It is possible to switch backward. For example, if the flip operation is detected for the first time, after switching the display of the first side to the display of the second side by inverting the three-dimensional function key, and then the flip operation is detected a second time, It is possible to return the display of the second side to the display of the first side by returning the key.

In this case, the display of the first surface and the second surface may be switched according to the direction of the flip operation. That is, when the flip operation is performed in one direction, the display on the first surface is switched to the display on the second surface, and when the flip operation is performed in the other direction (for example, the opposite direction in one direction) To the display of the first side. If the three-dimensional function key has three or more faces, the display of each face may be sequentially switched according to the number of flip operations. For example, when the flip operation is performed while the first side is displayed, the display is switched to the second side, and when the flip operation is performed again, the display can be switched to the third side. It goes without saying that the switching direction of the three-dimensional function key may also be changed according to the direction of the flip operation.

In addition, according to a further aspect related to the flip operation, the display switching of the first and second faces is performed taking into consideration the presence or absence of the flicking operation of the portable terminal 100 instantaneously, It is also possible to control. That is, when the flip operation is performed, the display switching is not performed when the threshold speed or intensity is smaller than the predetermined threshold speed or intensity, and the display switching can be performed when the flip operation is performed at the threshold speed or more. For example, when a flip operation is performed at a low speed or intensity, depending on the number of flip operations, the first, second, and third faces The display switching may be performed sequentially from the first side to the third side when the flip operation at a high speed or intensity occurs.

The storage unit 104 stores information to be displayed on each surface of the three-dimensional function key or identification information on the surface of the three-dimensional function key on which each information is to be displayed. For example, '0, 1, 2, ... 9' is stored as the display information on the first side, the name of the shortcut number information is stored as the display information on the second side, The telephone number of the information can be stored. At this time, the identification information of the name field of the table storing the abbreviated number can be mapped and stored as the display information of the second surface. Also, the identification information of the telephone number field of the table storing the abbreviated number can be mapped and stored as the display information of the third surface. As described above, information to be displayed on each surface of each function key can be mapped to the storage unit 104 and stored.

Also, the storage unit 104 may store information on the direction and order of switching of the three-dimensional function key. A defined graphical effect such as a switching order of each surface of the three-dimensional function key according to the user's tilting operation or a flip operation, a switching method, and the like. The switching order indicates the order of switching the respective sides of the three-dimensional function key according to the recognition of the user's operation (for example, the first side-> the second side- > the third side ...) (For example, switching according to the tilted angle, switching according to the tilted angle and direction, tilting over the critical angle, or switching immediately upon flip).

When the operation of the user is detected, the control unit 103 recognizes the display surface of the three-dimensional function key displayed on the portable terminal 100 at present. Then, the switching order stored in the storage unit 104 is loaded according to the detected user's operation, and the display surface of the switched three-dimensional function key is determined. Then, information corresponding to the switched display surface is extracted from the storage unit 104, the saved switching method is extracted from the storage unit, and the display surface of the three-dimensional function key is changed according to the extracted switching method and information.

On the other hand, in Fig. 1, each functional unit may be just an example of a logical division according to its function. In other words, the functions of the portable terminal 100 may be classified according to a criterion different from that shown in FIG. It goes without saying that each of the functional units may be implemented individually or in combination of two or more functional units, or a part of the functions performed in any one functional unit may be performed in one or more other functional units.

Figure 2 illustrates a three-dimensional function key according to one embodiment.

Referring to FIG. 2, the three-dimensional function key includes a first surface 201 and a second surface 202. The three-dimensional function key according to the present embodiment may mean that various input buttons related to functions (e.g., phone call, text message transmission, execution of a specific application) of the portable terminal are represented by graphic images. In other words, the user can touch and manipulate the three-dimensional function key to use and control various functions of the mobile terminal.

In Figure 2, the first side 201 of the three-dimensional function key corresponds to a keypad number. For example, on the first side 201, a number for entering a telephone number may be displayed when making a call. And the second surface 202 of the three-dimensional function key corresponds to the abbreviated number information. For example, the name of the contactee may be displayed on the second face 202. For example, in the case of the three-dimensional function key # 1 200, a numeral '1' is displayed on the first face 201 and a 'mama' mapped to the shortcut key '1' is displayed on the second face 202 . If the user presses and holds down the number '1' on the first face 201, a telephone connection is attempted to the 'mother'.

In Fig. 2, the three-dimensional function key can switch the display states of the first surface 201 and the second surface 202 according to the detected user's operation. The graphic effect on the way that the display state is switched can be determined reflecting the operation of the detected user. For example, when the user tilts the portable terminal at an angle, the three-dimensional function key can also rotate at a certain angle reflecting the degree of tilting of the portable terminal. Accordingly, a part of the first surface 201 and a part of the second surface 202 may be displayed together according to the inclination of the portable terminal. In this case, when the mobile terminal is tilted by a certain angle or more, the display may be switched from the first surface 201 to the second surface 202 by completely rotating the three-dimensional function key. When the user shakes the portable terminal instantaneously, It is also possible that the display of the first surface 201 is changed to the display of the second surface 202 while the dimension function key is instantly inverted.

For example, when the user calls the 'mother' designated by the shortcut key '1', the user presses the number '1' on the first face 201 to make a phone call or tilts the portable terminal It is possible to short-play the abbreviated-number information 'mother' of the second surface 202 and make a phone call after the two sides 202 are displayed. It is also possible to tilt the portable terminal slightly to check the information on the second side 202 and then return to the original state (i.e., display of the first side 201) and dial the 'mother' by pressing the number '1' .

According to another additional aspect, when the number key of the first surface 201 is displayed and the corresponding surface is short-pressed (hereinafter referred to as short touch), the corresponding number is input. In addition, when a number key of the first surface 201 is displayed, a long touch corresponding to a long touch key is extracted, and a phone number mapped to the extracted number is stored Is extracted from the abbreviated number table of the part (104). The extracted telephone number can then be dialed.

Also, when a short touch or a long touch is performed while the second surface 202 is displayed by a user operation, a value corresponding to the touched key (e.g., 'Hong Gil Dong' or '010-1234-5678') is extracted. Then, the attribute of the extracted value (for example, the name field and the telephone number field in the short number table) is judged and telephone connection can be made from the short number table of the storage unit 104 to the mapped telephone number. In this case, if the information displayed on the second surface 202 is the telephone number itself, the telephone connection can be made immediately without extracting the information in the abbreviated number table.

According to a further aspect, when a long touch is made in a state that the first surface 201 is displayed, it is also possible to extract and display a value corresponding to the second surface 202.

3 shows a three-dimensional function key according to another embodiment.

Referring to FIG. 3, the three-dimensional function key includes a first surface 301 and a second surface 302.

The first side 301 may correspond to a main button group. For example, Hangul characters for Hangul input can be displayed on the first side 301. The second side 302 may correspond to a sub-button group. For example, numeric / special characters for inputting numbers and special characters may be displayed on the second surface 302. For example, in the case of the three-dimensional function key # 1 300, the letter 'x' may be displayed on the first side 301 and the number '1' may be displayed on the second side 302.

The switching from the display state of the first side 301 to the display state of the second side 302 may be performed according to the operation of the user. For example, it is possible that the display state changes from the first surface 301 to the second surface 302 (or vice versa) whenever the user shakes the portable terminal instantaneously. If the user is prompted to enter a special character such as a question mark while the first face 301 is displayed, if the portable terminal is instantly shaken, the display state is changed to the second face 302, It is possible to return to the first surface 301 by momentarily shaking the portable terminal again after the special character displayed on the second surface 302 is input.

On the other hand, when the user tilts the portable terminal in a specific direction by a certain angle or more, the first surface 301 may be displayed and the second surface 302 may be displayed.

4 shows a display screen of a mobile terminal according to an embodiment.

Referring to FIG. 4, in the first screen 401, a user can press a long keypad number to call a contact object designated by the number. If the number '1' is mapped to 'Hong Kil Dong', the user can call Hong Kil Dong by pressing and holding the number '1' on the first screen 401.

However, if it is impossible to know how the user is mapped to the number '1' on the first screen 401 or the shortcut number of 'Hong Kil Dong', the user tilts the portable terminal in the backward or forward direction, 402 can be displayed.

When the second screen 402 is displayed as the portable terminal is tilted, the user can intuitively know that 'Hong Kil Dong' is assigned to the number '1', and 'Hong Kil Dong' is shortly displayed on the second screen 402 You can call Hong Kil-dong by pressing. Also, when the call is terminated, the user can tilt the mobile terminal again so that the first screen 401 is displayed. In this case, when the call is terminated, the first screen 401 may be displayed without a user's special operation, or a display initial screen (e.g., a home screen) of the portable terminal may be displayed.

According to an aspect, when the user tilts the portable terminal a little, the number of each keypad of the first screen 401 also gradually rotates according to the degree of tilting of the portable terminal, so that the first surface 410 and the second surface (420) can be simultaneously displayed. Subsequently, when the user tilts the portable terminal further, the first screen 410 of each function button may move backward and a second screen 402 of the second screen 420 may be displayed. Therefore, if you are wondering who is assigned to the number '1', you can see 'Hong Kil Dong' by tilting the mobile terminal.

According to a further aspect, the degree of tilting of each of the three-dimensional function keys can be determined by reflecting the inclination degree of the portable terminal. For example, it is possible to rotate the three-dimensional function key in the same manner as the tilted angle of the portable terminal.

5A shows a display screen of a portable terminal according to another embodiment.

Referring to FIG. 5A, a first surface 510 of a three-dimensional function key is displayed on a first screen 501, a second surface 510 of a three-dimensional function key is displayed on a second screen 502, ) May be displayed. A keypad number for inputting a telephone number may be displayed on the first surface 510 and identification information of the contact destination designated by each number may be displayed on the second surface 520.

The switching from the first screen 501 to the second screen 502 can be controlled by the user's flip operation. For example, if the user instantaneously bounces the portable terminal, the first screen 501 may be changed to the second screen 502. [

The graphic effect in the change process is not particularly limited. For example, as shown in FIG. 4, the three-dimensional function key may be changed while being rotated . As shown in FIG. 5A , a part of the three-dimensional function key may be changed while being folded. It is also possible for the first face of the three-dimensional function key to change to the second face or to change immediately from the first face to the second face.

5B shows a display screen of the portable terminal according to another embodiment.

Referring to FIG. 5B, it is possible to switch from the first screen 501 to the second screen 502 by the flip operation in the first direction, and to perform the flip operation in the first direction, To a third screen (503). Similarly, the third screen 503 to the fourth screen 504 can be switched by a flip operation in an additional first direction. At this time, the abbreviated number corresponding to the numeric keypad 0 to 9 on the first screen 501 can be displayed on the second screen 502, and the abbreviated number history corresponding to the abbreviated number history 10 to 19 can be displayed on the third screen 503 Can be displayed. In the fourth screen 504, abbreviated numbers corresponding to 20 to 29 can be displayed. In this manner, a plurality of abbreviated number details can be sequentially displayed.

Conversely, a flip operation in a second direction opposite to the first direction causes the third screen 503 to move from the fourth screen 504 to the third screen 503 to the second screen 502, The second screen 502 may be switched to the first screen 501. In another embodiment, regardless of the current screen being displayed, if the flip operation occurs in the second direction, the numeric keypad may be always switched to the first screen 501 to be displayed.

Here, for example, the first direction may be defined as the forward direction of the mobile terminal, and the second direction may be defined as the rear direction of the portable terminal. However, the present invention is not limited to any one direction and both the first direction and the second direction may be conceptually reversed Do.

Meanwhile, the embodiment of FIG. 5B may be implemented by a method as shown in FIG. More specifically, when the first screen 501 is displayed and the first screen 502 and the third screen 503 are tilted in a first direction by a predetermined angle or more (more than a threshold angle) As shown in FIG. At this time, after the terminal is tilted in the first direction by more than a predetermined angle to switch the screen from the first screen 501 to the second screen 502, the terminal is returned to the original angle, The screen is switched from the second screen 502 to the third screen 503. In a state where the first screen 501 is displayed, if the terminal is tilted by more than a certain angle in the first direction and the screen is switched from the first screen 501 to the second screen 502, The third screen 503, the fourth screen 504, and the like may be configured to sequentially switch the screen. On the other hand, the critical angle can be arbitrarily set by the user.

In addition, it is also possible to reverse the screen in the reverse direction by tilting in the second direction opposite to the first direction. That is, the third screen 503, the second screen 502, and the first screen 501 are sequentially displayed on the screen 503 by tilting the terminal at a predetermined angle or more in the second direction while the fourth screen 504 is displayed. The conversion can be configured to be performed. On the other hand, it is also possible to always switch to the first screen 501 when an operation to tilt more than a certain angle in the second direction occurs, irrespective of which screen is currently displayed.

As described above with reference to FIGS. 5A and 5B, the graphic effect in the screen switching process is not particularly limited. For example, as shown in FIG. 4, the three-dimensional function key may be rotated, or the three-dimensional function key may be rotated as shown in FIGS. 5A and 5B. It is also possible that the first surface of the three-dimensional function key disappears and changes to the second surface or immediately changes from the first surface to the second surface.

FIG. 6 shows a setting screen relating to a display method of a three-dimensional function key according to an embodiment.

Referring to FIG. 6, the user can select 'display' in the main setting window 601 to display the display setting windows 602a, 602b and 602c. When the user selects 'DIAL' in the display setting windows 602a, 602b and 602c, a predetermined toggle button 602 is displayed, and the user touches the toggle button 602 to select one of the three dial modes .

As an example, the dial mode is a '3D tilt' mode in which a call connection is made after confirming a speed dial number through a gesture that tilts the terminal backward, a '3D flip' mode in which a call connection is made through a gesture, Mode, and a 'classic white' mode that provides a basic dial skin without gestures on the terminal dial. However, it should be understood that the three modes herein are for illustrative purposes only and various modes may be used.

FIG. 7 illustrates a three-dimensional function key display switching method of a portable terminal according to an embodiment.

Referring to FIGS. 1 and 7, first, an operation of a user is detected (701). For example, the operation detecting unit 101 can detect a tilting operation, which is an operation of tilting the portable terminal during a user's operation with respect to the portable terminal, or a flip operation, which is an operation of flicking the portable terminal backward. In the case of a tilting operation, at least one of a tilted direction and an angle may be detected, and in the case of a flip operation, at least one of the flipped directions may be detected.

Then, the three-dimensional function key is displayed (702). For example, the display unit 102 has at least two surfaces, a keypad number for inputting a telephone number is mapped on the first surface, and a three-dimensional function key for mapping the shortcut number information corresponding to the keypad number on the second surface. Can be displayed.

Then, the display switching of the three-dimensional function key is controlled according to the detected operation (703). For example, when the control unit 103 detects the tilting operation or the flip operation, it is possible to rotate the three-dimensional function key to switch the display on the first surface to the display on the second surface.

According to a further aspect, the information displayed on each side of the three-dimensional function key, the order and effect of switching the display of the three-dimensional function key according to the user's action, etc., can be determined according to the previously stored setting information. For example, the control unit 103 can control the display switching with reference to the setting information stored in the storage unit 104. [ In other words, the information corresponding to the switched display surface is extracted from the storage unit 104, the saved switching method is extracted to the storage unit 104, and the display surface of the three-dimensional function key is changed It is possible to do.

8A to 8C illustrate a method of switching the three-dimensional function key display of the portable terminal according to another embodiment.

8A, a widget icon such as a home screen is formed in three dimensions in addition to an individual three-dimensional function key such as a dial or an input device, and the display surface is three-dimensionally changed according to a user's operation so as to be directly converted to an association function can do. For example, when the user applies a tilting operation or a flip operation to the portable terminal, the clock icon 801 is rotated with respect to the predetermined rotation axis 802 so that the back face 803 of the clock icon 801 is rotated It is possible to display it. If the clock icon 801 displays the current time, the alarm function can be executed immediately after the user touches the back surface 803 by mapping the 'alarm', which is an associated function, on the back surface 803.

In FIG. 8A, however, the association function is mapped and displayed on the back side 803 of the clock icon 801, which is an illustrative example to facilitate understanding. Accordingly, the clock icon 801 may be formed of a polyhedron, a clock function may be provided on the front surface, an alarm function may be provided on the right surface, and a stopwatch function may be mapped and displayed on the rear surface.

Referring to FIG. 8B, it is also possible that the GUI of the menu screen is directly converted to an associated menu such as a task manager. For example, when a predetermined operation such as a tilt operation or a flip operation is detected on the main menu screen or the desktop screen 804 on which the application execution icon is displayed, the screen is switched to the operation manager screen 805 indicating the CPU occupation rate of each application It is possible. As an example of the related menu, various menu screen display forms other than the task manager can be used.

Referring to FIG. 8C, it is possible that the buttons in the launcher 806 at the lower one of the display screens of the portable terminal are switched to the buttons in which the association function is executed according to the user's operation. For example, in the case of the text message icon 807, every time a predetermined operation (for example, shaking the portable terminal) is performed, the name of the contact object to which a lot of recent text messages are sent is toggled, ). ≪ / RTI >

Also, although not specifically shown, in the case of using a camera provided in a portable terminal, the embodiment according to the present invention is an example in which a camera operated according to a user's operation is switched from a front camera to a rear camera or vice versa Can be applied.

When a text message or a KakaoTop Push message is received on a screen on which a DMB or a video player is received, if the mobile terminal is flipped or tilted in one direction is detected, the screen is displayed as a text message or a KakaoTop Push message Or a message can be displayed at an inclined angle. It is also possible to switch directly to a text message or a KakaoTalk app execution screen by flip or tilt operation.

On the other hand, as an additional example, if a flip or tilt operation is detected, the foreground and background applications may be switched or some screens may be switched to another screen.

As described above, according to the disclosed embodiment, since the display state of the three-dimensional function key is changed by the simple operation of the user, the function or the shortcut number information mapped to each function key can be intuitively recognized.

Meanwhile, the embodiments of the present invention can be embodied as computer readable codes on a computer readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored.

Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device and the like, and also a carrier wave (for example, transmission via the Internet) . In addition, the computer-readable recording medium may be distributed over network-connected computer systems so that computer readable codes can be stored and executed in a distributed manner. In addition, functional programs, codes, and code segments for implementing the present invention can be easily deduced by programmers skilled in the art to which the present invention belongs.

Further, the embodiments described above are intended to illustrate the present invention, and the scope of the present invention is not limited to the specific embodiments.
