In step S440, the device 100 may receive the second input via the button 110. [ For example, the device 100 may determine whether a touch gesture indicating the direction of movement is generated based on the touch point at which the first input is received. The touch gesture indicating the movement direction may be a touch gesture such as the above-described swipe, but is not limited thereto.

The touch gesture according to an exemplary embodiment of the present invention may indicate a moving direction to a touch gesture in which the first input moves a predetermined distance with respect to the received touch point. A touch gesture according to an exemplary embodiment of the present invention may indicate a movement direction using a touch gesture in which a finger is tilted at a touch point at which a first input is received. For example, the first input may indicate a leftward movement using a touch gesture that tilts the finger further to the left (or presses the left further) at the received touch point. Conversely, a rightward movement can be indicated using a touch gesture in which the first input is tilted to the right (or the right is further touched) at the received touch point. The device 100 may be configured to detect the above-described movement direction by sensing the change of the touch surface on the button 110 due to the tilting of the finger.

If the second input reception is recognized in step S440, the device 100 displays a screen on the display 120 that switches the task screen in accordance with the second input. For example, if the second input indicating the movement in the left direction or the right direction is possible through the button 110 and the currently input second input is the input indicating the movement in the left direction, A screen for switching the task screen in the left direction can be displayed. If the currently input second input is an input indicating movement in the right direction, a screen for switching the task screen from the left to the right based on the task currently being executed can be displayed.

6A to 6D are views showing an example of a task switching method performed by the device 100 according to an embodiment of the present invention.

6A, when the messenger service is executed by the device 100, the touch input for the button 110 is sensed and the touch input for the button 110 is displayed as shown in FIG. 6B If it is detected that the device 100 has been continuously operated for a predetermined time, the device 100 can recognize that the touch-based first input is received through the button 110. [

If the first input is recognized as being received, the device 100 may set the operation mode to the task switching mode. Accordingly, the device 100 arranges the task screens 621 to 624 to be switched based on the captured current task screen 610 and the second input to be received, as shown in Fig. 6C. The task screens 621 to 624 to be switched as shown in FIG. 6C are based on history information about recently used applications by the device 100.

As the second input representing the movement in the right direction is received via the button 110, the device 100 displays the task screens 621 to 624 arranged on the basis of the current task screen 610 as shown in FIG. 6D And performs task switching from left to right. Due to the task switching, the task screen that is focused on the display 120 of the device 100 is changed.

7 is a flowchart illustrating a task switching method performed by the device 100 according to an embodiment of the present invention.

The flowchart of FIG. 7 is an example in which a process of executing a task corresponding to the switched task screen is added to the flowchart of FIG. Therefore, the steps S710 to S750 of FIG. 7 are the same as the steps S410 to S450 described above, so that the description will be omitted in order to avoid redundant description.

In step S760, the device 100 executes a task corresponding to the task screen focused on the display 120 if the touch-based input is not received via the button 110 for a predetermined time. For example, when the list screen 622 is being displayed on the display 120 by task switching as shown in FIG. 6D, if no touch-based input is received over a period of time via the button 110, 100 may execute the task corresponding to the list screen 622. [ Accordingly, the user can select an item included in the list screen 622. [

The device 100 may be configured to execute a task corresponding to the task screen focused on the display 120 if the touch-based input is not received via the button 110 without considering the predetermined time.

If the display 120 is a touch screen, step S760 is performed to display a task corresponding to the focused task screen when a touch input indicating selection of the currently focused task screen is received via the touch screen before the predetermined time elapses, .

8 is a flowchart illustrating a task switching method performed by the device 100 according to an embodiment of the present invention. 8 is an example in which the button 110 can input fingerprint data and touch input.

When the task is being executed by the device 100 in step S810 of Fig. 8, the device 100 may receive the fingerprint data via the button 110 in step S820. The button 110 may be configured by a fingerprint recognition sensor capable of capturing a stripe of the fingerprint of the finger by slightly touching the finger on the button 110. [

In step S830, the device 100 can determine whether the received fingerprint data is included in the previously registered fingerprint data. To this end, the device 100 may store fingerprint data serving as a determination criterion. If it is determined that the received fingerprint data is included in the previously registered fingerprint data, the device 100 performs steps S840 to S880. Steps S840 to S880 perform the same operations as the steps S720 to S760 of FIG. 7, so that the description thereof will be omitted in order to avoid redundant description.

As a result of the determination in step S830, if the received fingerprint data is not included in the previously registered fingerprint data, the device 100 does not receive the touch-based input via the button 110. [

9 is a flowchart illustrating a task switching method performed by the device 100 according to an embodiment of the present invention. 9 is an example in which the button 110 can input fingerprint data and touch input. 9 shows a case in which the operation of the device 100 is performed in the guest mode when the fingerprint data received via the button 110 is not included in the fingerprint data registered in advance.

Steps S910 to S980 of FIG. 9 are performed in the same manner as steps S810 to S880 of FIG. Therefore, a description thereof will be omitted in order to avoid redundant description.

If the fingerprint data received in step S930 of Fig. 9 is not included in the previously registered fingerprint data, the device 100 executes the guest mode in step S990. The guest mode is preset in the device 100. The guest mode may be preset by the user of the device 100. A user who is not previously registered with the device 100 can use the device 100 to execute the guest mode, thereby using the basic functions provided by the device 100. [

10 is a flowchart illustrating a task switching method performed by the device 100 according to an embodiment of the present invention. 10 shows a case where the operation state of the device 100 is in the lock screen state.

When the operation status of the device 100 is locked screen status in step S1010, the device 100 can receive fingerprint data via the button 110 in step S1020. At this time, the device 100 may display a guidance message on the display 120, that is, a lock screen state using fingerprint data. However, the message " lock screen state using fingerprint data " may not be output.

In step S1030, the device 100 can determine whether the received fingerprint data is included in the previously registered fingerprint data. As a result of the determination, if the received fingerprint data is included in the previously registered fingerprint data, the device 100 releases the lock screen in step S1040.

In step S1050, the device 100 performs task switching in the host mode according to the touch-based input through the button 110. [ The input touch-based input may include a first input and a second input.

As a result of the determination in step S1030, if the received fingerprint data is not included in the previously registered fingerprint data, the device 100 can maintain the locked screen state in step S1060.
