When the communication unit 330 is provided in the mouse module 300 as in the wireless mouse system 2000 described above with reference to FIG. 2, a position movement signal is received by wireless communication connected to the mouse module 300 . ≪ / RTI >

In step S440, the controller 220 may generate at least one of the button selection signal and the wheel drive signal according to the user's input. Here, the button selection signal or the wheel drive signal may be a signal generated by a user clicking a left or right click button in an actual mouse, or a signal corresponding to a signal generated by moving a wheel upward or downward.

In the touch input type portable terminal 200, the button selection signal may be generated by an input which touches at least a part of the area displayed on the display part 210 by one of the left button image and the right button image. That is, when an area in which the left button image is displayed is touched, a left button selection signal is generated. When an area in which the right button image is displayed is touched, a right button selection signal is generated.

In addition, the wheel drive signal may be generated by an input that is dragged upward or downward after touching at least a portion of the area on the display unit 210 on which the wheel image is displayed.

In step S450, the control unit 220 may transmit the received position movement signal, the button selection signal generated by the user input, or the wheel drive signal to the linked external device. That is, the position movement signal, the button selection signal, or the wheel drive signal may be transmitted through the wireless communication with the external device in the mouse mode.

The external device receives the position movement signal, the button selection signal, or the wheel drive signal, thereby moving the mouse pointer displayed on the display unit of the external device, selecting an arbitrary execution icon, or scrolling the screen Accordingly, the user can operate the mouse while viewing the display unit of the external device.

On the other hand, if the user releases the mouse module 100 by disconnecting the mouse module 100 from the portable terminal 200, or the wireless communication connection with the external device is released and the link with the external device is released, The controller 220 can end the mouse mode. In addition, the mouse mode may be terminated by the user's mouse mode end input. If the wireless mouse application is switched to the background application by receiving a call or the like according to the embodiment, the mouse mode is suspended, Once switched to the executing application, the mouse mode may be implemented to be redone.
