For example, task screen 1-1 is a screen of a task used before the current task screen 160, and task screen 1-2 is a screen of a task used before task screen 1-1. However, the left and right task screen 1-1 and task screen 1-2 are not limited to an arrangement based on usage history information of the device 100.

Task screen 2+2, task screen 2+1, task screen 2-1, and task screen 2-2 shown in FIG. 5 are task screens arranged based on the task being executed by the device 100 have. For example, task screen 2+2, task screen 2+1, task screen 2-1, and task screen 2-2 are screens captured from a task that is being multitasked with a task corresponding to the current task screen 160. .

The task screen 3+2, task screen 3+1, task screen 3-1, and task screen 3-2 in the northeast and southwest directions shown in FIG. 5 are task screens arranged based on categories set in the device 100. I can.

Task screen 4+1, task screen 4-1, and task screen 4-2 in the southeast and northwest directions shown in FIG. 5 may be task screens based on folders set in the device 100.

However, the task switching target according to the second input that can be received through the button 110 is not limited to that shown in FIG. 5.

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

A touch gesture according to an embodiment of the present invention may indicate a moving direction as a touch gesture moving a predetermined distance based on a touch point from which a first input is received. A touch gesture according to an embodiment of the present invention may indicate a moving direction by using a touch gesture in which a finger is tilted at a touch point at which a first input is received. For example, a leftward movement may be indicated by using a touch gesture in which the finger is tilted to the left (or pressed further to the left) at the touch point where the first input is received. Conversely, a rightward movement may be indicated by using a touch gesture in which the finger is further tilted to the right (or pressed further to the right) at the touch point where the first input is received. The device 100 may be configured to detect a change in the touch surface on the button 110 due to the inclination of the finger, and determine the above-described movement direction.

When the reception of the second input is recognized in step S440, the device 100 displays a screen for switching the task screen according to the second input on the display 120. For example, a second input indicating movement in the left or right direction is possible through the button 110, and if the currently input second input is an input indicating movement in the left direction, the right side based on the currently executing task You can display a screen that switches the task screen from to the left. If the currently input second input is an input indicating movement in the right direction, a screen for switching the task screen from left to right based on the currently executing task may be displayed.

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

As shown in FIG. 6A, when a messenger service is being executed by the device 100, a touch input to the button 110 is sensed, and a touch input to the button 110 is performed as shown in FIG. 6B. When it is sensed that the lasting for a certain period of time is detected, the device 100 may recognize that the first touch-based input has been received through the button 110.

When it is recognized that the first input has been received, the device 100 may set the operation mode to a task switching mode. Accordingly, the device 100 arranges the captured current task screen 610 and the task screens 621 to 624 to be switched based on the second input to be received, as shown in FIG. 6C. As shown in FIG. 6C, the task screens 621 to 624 to be switched are based on historical information about an application recently used by the device 100.

Therefore, since steps S710 to S750 of FIG. 7 are the same as steps S410 to S450 described above, the following description will be omitted to avoid redundant description.

In step S760, if a touch-based input is not received through the button 110 for a certain period of time, the device 100 executes a task corresponding to the task screen focused on the display 120. For example, as shown in FIG. 6D, when the list screen 622 is displayed on the display 120 by task switching, if a touch-based input is not received through the button 110 for a certain period of time, the device ( 100) may execute a task corresponding to the list screen 622. Accordingly, the user can select an item included in the list screen 622.
