4 is a flowchart provided to explain a method for controlling a portable terminal according to the first embodiment of the present invention. Referring to FIG. 4, when a key defined to power on the mobile terminal 100 is pressed in the user input unit 130, the controller 180 performs a booting process to configure a touch screen. The display unit 151 displays an idle screen by the controller 180 (S200). In general, the touch screen is turned off after a predetermined time to save power, and when there is a touch input through the touch screen or a key input through the user input unit 130, the touch screen is turned on again. The standby screen is displayed on the screen.

In the state where the standby screen is displayed as described above, the controller 180 according to the value output from the acceleration sensor 143, the first and second body 100A such that the display direction of the display unit 151 is perpendicular to the ground. , 100B) determines whether or not it has moved in a lying state (S205).

As a result of the determination in step S205, when the first and second bodies 100A and 100B move in the lying state, the controller 180 controls the preset operation menu to be executed (S210). In this case, examples of the preset operation menu may include a web access menu, a notepad menu, an image view menu, and the like. When the end of the operation menu executed in this way is selected (S215), the controller 180 displays the standby screen again (S200). According to the usage environment, the first and second bodies 100A and 100B are erected, that is, the first and second bodies 100A and 100B are arranged so that the display direction of the display unit 151 is parallel to the ground. When moved, the executed action menu may be configured to end.

Next, the controller 180 determines whether shaking of the first and second bodies 100A and 100B is detected based on the value output from the acceleration sensor 143 (S220). Shaking of the first and second bodies 100A and 100B means a case of reciprocating with respect to a predetermined axis. In this case, the display unit 151 also reciprocates with respect to a predetermined axis. When the shaking of the first and second bodies 100A and 100B is detected, the controller 180 switches a user interface of the standby screen to display a new standby screen or controls to execute a preset shortcut menu (S225). .

The controller 180 has a horizontal direction, that is, the length direction of the first body 100A is parallel to the ground in a state where the first and second bodies 100A and 100B are erected according to the value output from the acceleration sensor 143. In the case of moving in the direction, the display unit 151 controls to display the contents of the screen in the first direction, which is the longitudinal direction of the first body 100A (S325).

According to a value output from the acceleration sensor 143, the controller 180 may have a vertical direction, that is, a length direction of the first body 100A perpendicular to the ground in a state where the first and second bodies 100A and 100B are erected. In the case of moving in the direction, the display unit 151 controls to display the contents of the screen in the width direction of the first body 100A rotated 90 degrees in the first direction (S245). When a user command is input through the user input unit 130, the controller 180 controls an operation corresponding to the input user command to be performed (S255). By such a process, the related operation may be performed according to the movement of the first and second bodies 100A and 100B.

5 is a flowchart provided to explain a method for controlling a portable terminal according to the second embodiment of the present invention. In the present embodiment, a voice call is described as an example.

Referring to FIG. 5, when a phone number of a counterpart terminal is input and a call is selected to request a voice call, the controller 180 controls the wireless communication unit 110 to control a voice call connection with the counterpart terminal (S300). In operation S305, the opposite terminal performs a voice call according to the input telephone number. During a voice call, a voice signal of a user is input through the microphone 123, and a voice signal of the counterpart transmitted from the counterpart terminal is output through the sound output module 153.

During the voice call, the controller 180 determines whether the first and second bodies 100A and 100B are moved in a down state or in a standing state according to the value output from the acceleration sensor 143 (S310). , S320). As described above, the state in which the first and second bodies 100A and 100B are laid down means a state in which the display direction of the display unit 151 becomes a direction perpendicular to the ground, and the first and second bodies ( The standing state of 100A and 100B means a state in which the display direction of the display unit 151 becomes a direction parallel to the ground.

As a result of this determination, when the first and second bodies 100A and 100B move in a standing state, the voice call mode is maintained (S310 and S315).

However, when it is detected that the first and second bodies 100A and 100B move in a lying down state, the controller 180 can process two or more tasks at the same time or execute two or more programs simultaneously. The operation is switched to the tasking mode (S325). In addition, the controller 180 controls the voice call to be set at the same time (S330). In this case, examples of the set operation may include driving of a web browser, a speakerphone mode, a memo pad mode, and the like. If the speakerphone mode is executed, the sensitivity of the microphone 123 may be adjusted to suit the use of the speakerphone mode, or may be controlled to have omnidirectionality.

When the first and second bodies 100A and 100B move in the standing state while being switched to the multitasking mode, the controller 180 controls to switch to the voice call mode in which only the voice call is performed (S310, S315). This operation is repeatedly performed until call termination is selected.

6 is a flowchart provided to explain a method for controlling a portable terminal according to the third embodiment of the present invention. In this embodiment, the case of a video call will be described as an example.

Referring to FIG. 6, when the phone number of the counterpart terminal is input and a video call hotkey is pressed and a video call is requested, the controller 180 controls the wireless communication unit 110 to correspond to the counterpart terminal according to the input phone number.
