Hereinafter, a method of controlling an operation of a mobile terminal according to the present invention will be described in detail with reference to the accompanying drawings.

5A is a first flowchart of a method of controlling an operation of a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 5A, the mobile terminal 100 executes a specific application among at least one application under the control of the controller 180 (S511).

Here, the at least one application may include executable functions using the mobile terminal 100. For example, at least one application may include phone book related applications, call / message related applications, MP3 related applications, broadcast related applications, camera related applications, and the like.

Further, a particular application may be executed in the foreground or background, in a multitasking state in which a plurality of applications (including a specific application) are running simultaneously.

The mobile terminal 100 determines the execution state of the specific application being executed in the execution step S511 under the control of the control unit 180 (S513).

Here, the execution state may include a specific terminal operation state according to execution of a specific application.

For example, the execution state may be a state in which a call is received in a call connection state, a state in which a telephone number is input, a state in which an outgoing call is awaited, a state in which an incoming call is awaited, And the like. The execution state may include a specific contact information display state registered on the phone book, a contact list display state registered on the phone book, and the like when the application being executed is a phone book related application. In addition, the execution state may include a specific reception message display state, a reception message list display state, and the like when the executing application is a call / message related application. In addition, the execution state may include a display state such as a recent calling / receiving list, a missed phone list, a frequently used call / message list, etc., when the executing application is a call / message related application.

The mobile terminal 100 may receive a designation operation for designating a light emission color for each command signal through the user input unit 130 prior to the execution of the output step S515 to be described later, The light emission color can be designated for each command signal in accordance with the input operation.

In this regard, it will be described in detail with reference to Figs. 6A and 6B.

6A), the mobile terminal 100 displays a screen for designating the light emission color of the smart key 410 for each command signal (FIG. 6A) (Fig. 6B).

Accordingly, the user can specify the color of light emitted by the smart key 410 for each command signal through the screen shown in FIG. 6B.

For example, according to a designation operation input from the user, the mobile terminal 100 displays green for the confirmation command signal, green for the call command signal, and red for the end command signal, , Yellow for confirmation command signal of new message, blue for confirmation command signal of new e-mail, violet for confirmation command signal of missed call and orange for battery command confirmation signal of low voltage state .

Furthermore, the mobile terminal 100 may perform a notification operation of the corresponding event to the user by using the emission color designated for each of the new message, the new e-mail, the missed call, and the battery alert of the low voltage state.

Meanwhile, although not shown in the drawing, the mobile terminal 100 may set the emission color for the command signal differently for each application. For example, the emission color corresponding to the termination command signal in the telephone directory related application may be designated as red while the emission color corresponding to the termination command signal in the MP3-related application may be designated as yellow color.

5, the mobile terminal 100 transmits the light emission color corresponding to the command signal that can be input in the execution state determined in the determination step S513, using the smart key 410, under the control of the control unit 180 And outputs it (S515).

For example, since the command signal that can be input in the call connection state is an end command signal of the call connection state, the smart key 410 can output a red corresponding to the termination command signal of the call connection state {smart key_ red (411)}. Alternatively, since the command signal that can be input in the reception call connection wait state is the connection command signal of the received call, the smart key 410 can output green corresponding to the connection command signal of the received call {smart key_green ( 412)}.

The light emission color output of the smart key 410 according to the execution state will be described in more detail below with reference to the accompanying drawings.

When the smart key 410 is activated (S517) during the execution of the output step S515, the mobile terminal 100 determines whether the light emission color output from the outputting step S515 is instructed by the control unit 180 And performs an operation corresponding to the command signal (S519).

For example, when the smart key_ red 411 is activated in the call connection state, the control unit 180 may terminate the call connection state according to the termination command signal of the call connection state. Alternatively, when the smart key_green 412 is activated in the reception call connection standby state, the control unit 180 can connect the received call in accordance with the connection command signal of the received call.

The operation of the smart key 410 according to the activation will be described in more detail below with reference to the accompanying drawings.

7A to 7F are screen configuration diagrams illustrating a light emitting color of a smart key according to an execution state of a call / message related application according to an embodiment of the present invention.
