3 is a flow chart illustrating a method for performing multiple tasks in a mobile terminal in accordance with one embodiment of the present invention.

Referring to FIG. 3, the controller 180 executes a predetermined task according to data generated from the user input unit 130 (S101). For example, when a message application program is selected among various application programs displayed on the idle screen (home screen), the control unit 180 executes the message application program. Then, the control unit 180 enters a message creation mode for creating a message according to a user input, and outputs the message creation screen to the display unit 151.

The controller 180 receives an input for instructing execution of a multitask from the user input unit 130 during the predetermined operation (S102).

The method for inputting the multi-task command may use any one of the following methods. First, if a key assigned to a multi-task (multi-task) among the keys provided in the user input unit 130 is pressed, the control unit 180 recognizes the multi-task command. Second, as shown in FIG. 4, a long touch is sensed at one point A of one side of a message creation screen during message creation, and after detecting the long touch, The controller 180 recognizes the drag as a multi-task request when the drag is detected at one point B on the boundary parallel to the one edge. Third, when a drag is input to one side boundary of the display screen facing the one side boundary, the sensing unit 140 senses the drag. The controller 180 calculates the width of a line drawn by the detected drag input. If the width of the drag line is below the threshold value, the controller 180 recognizes the drag input as a multi-task request. That is, the control unit 180 recognizes the multi-task command or the general drag command according to the contact area between the pointing unit and the display screen. For example, if the dragging of the line to the nail is input, the control unit 180 recognizes it as a multi-task command, and if a drag having a predetermined line width is input to the finger tip, the controller 180 performs general drag (object movement, handwriting input, .

Upon receiving the multi-task command, the controller 180 divides the display screen (S103). At this time, if a drag is input on the display area where the currently running work screen is displayed, the controller 180 divides the display area based on the point where the drag input is sensed. Alternatively, the control unit 180 may divide the display screen according to predetermined information.

When the screen is divided, the control unit 180 displays execution information (an execution screen, a work screen) of the predetermined job in one of the divided areas and displays a job list capable of multi-tasking in any other area (S104). That is, the control unit 180 divides the display area in which one running work screen is displayed into the first display area and the second display area on the basis of the multiple work instruction, displays the running work screen on the first display area , And displays a list of application programs capable of multi-tasking in the second display area.

If one of the displayed job lists is selected, the controller 180 executes the selected job and displays an execution screen of the selected job in the other area (S105, S106). For example, if a task different from the currently executed task is selected from the list of application programs displayed in the second display area, the controller 180 executes the selected task and displays the execution screen (selected task screen) .

5A and 5B illustrate a process of executing a multi-task using a screen division of a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 4, the controller 180 divides the display screen into an indicator display area 200 and an information display area 300 that displays an operation state and data according to execution of a predetermined task. A screen of the executed job is displayed in the information display area 300. [ For example, when the user selects a message function to create a message, the control unit 180 executes a message function and displays a message creation screen in the information display area 300. [

When a multi-task command is input on the information display area 300 in which the message preparation screen is displayed, the controller 180 displays the information display area 300 according to the multi-task command in the first display area 310 and the second display area 320. [ The control unit 180 displays the running message creation screen on the first display area 310 and displays an application program list (menu list) on the second display area 320 that can perform multiple tasks.

If one of the application programs displayed in the second display area 320 is selected, the controller 180 executes the selected application program and displays the execution screen in the second display area 320. [ For example, as shown in FIG. 5B, when 'camera' is selected from the application program list displayed in the second display area 320, the controller 180 drives the camera 121 and displays a preview screen And is displayed on the second display area 320. [

6A to 6E show another example of a process in which a mobile terminal related to the present invention executes multiple jobs.

Referring to FIG. 6A, the controller 180 executes a message function according to a control signal input by a user, and displays a message creation screen on the information display area 330 of the display screen. Hereinafter, for convenience of explanation, the information display area 330 is used in combination with a display screen.

When a drag (321) is input from the A point to the B point in the boundary of the display screen on which the message creation screen is displayed, the controller 180 displays the display screen 330 on the basis of the position where the drag is input 1 display area 331 and the second display area 332. [ The control unit 180 displays a message creation screen in the first display area 331 and a list of application programs (operation) in the second display area 332. [

If the user selects 'camera' from the application program list displayed on the second display area 332, the controller 180 drives the camera 121 and displays a preview screen on the second display area 332, as shown in FIG. 6C. .

6C, when the drag input 322 is generated from point C to point D in the first display area 331, the controller 180 detects the drag input 322 through the sensing unit 140 do. 6D, the controller 180 displays the first display area 331 as the first display area 331 and the second display area 332 as the reference line (dividing line) 322 connecting the C and D points, And the third display area 333. In other words, the controller 180 inserts the third display area 333 between the first display area 331 and the second display area 332. The control unit 180 displays a message creation screen in the first display area 331 and displays an application program list in the third display area 333. [

If 'calendar' in the application program list displayed in the third display area 333 is selected, the control unit 180 executes the calendar and displays the execution screen of the executed calendar in the third display area 333 as shown in FIG. 6E do.

In this embodiment, the display screen is divided into three areas, and the maximum number of the divided areas can be limited. In other words, it is possible to limit the number of work screens that can be simultaneously displayed on one display screen. The number of work screens that can be displayed on one screen can be changed according to the resolution and size of the display unit 151. [ In addition, considering the performance of the control unit (processor) 180, the number of tasks that can be executed simultaneously can be limited.

FIG. 7 shows an example of adjusting the size of the work screen of the mobile terminal according to the present invention.

Referring to FIG. 7, the controller 180 divides the display screen into two areas, displays a message creation screen in one of the divided areas, and displays a preview screen of the camera in the other area . That is, the control unit 180 divides the display screen according to the multi-task command, executes different tasks in each of the divided regions, and displays the execution screen.

If a long touch is input to one side of a work screen for changing the size of the work screen among the multiple jobs being executed, the controller 180 detects the long touch input and enters a work screen size edit mode (a) . In other words, when the long touch is input to the boundary for dividing the divided regions, the controller 180 enters an operation mode for adjusting the size of the divided region.

As shown in (b), when the drag is inputted in the predetermined direction following the long touch, the controller 180 relatively adjusts the sizes of the divided regions according to the drag direction (c). For example, when a long touch is input to the top of the preview screen of the camera and a drag is input in the direction of the message creation screen, the control unit 180 increases the preview screen size of the camera according to the input drag distance, (C) Reduce the size of the message creation screen by increasing the view screen size.

When adjusting the size of the work screen displayed in the divided area as in the present embodiment, the screen size can be adjusted within the provided guide line. That is, the maximum size and the minimum size of the divided areas can be limited.

8A and 8B show an example of changing the working screen position of the mobile terminal related to the present invention.

According to FIG. 8A, the controller 180 divides the display screen and displays different work screens in the divided areas. For example, the control unit 180 displays execution screens of " job 1 "and" job 2 "selected by the user in different divided areas. If you want to switch between the positions of "Task 1" and "Task 2", drag "Task 1" to the area where "Task 2" is displayed, and simultaneously "Task 2" The control unit 180 recognizes the command as a position exchange command of "job 1" and "job 2 ". Therefore, the control unit 180 exchanges the positions where the "job 1" and "job 2" are displayed as shown in the figure.

Referring to FIG. 8B, when dragging a work 1 screen while three works are being executed on one screen and dragging the screen to the boundary between the work 2 and the work 3 screens, the controller 180 displays the work 1 screen on the work 2 screen 3 Insert between screens. Accordingly, the control unit 180 rearranges and displays the work screens according to the change of the position of the work screen.

FIG. 9 is a flowchart illustrating a multi-task management method of a mobile terminal according to the present invention.

According to the procedure shown in FIG. 3, the controller 180 divides the display screen into at least two areas, performs different tasks on each of the divided areas, and displays the execution screen (S201).

The controller 180 detects a touch gesture input to any one of the divided areas during the multi-tasking through the screen division (S202). The touch gesture refers to inputting a symbol, a figure, a character, or the like as a pointing means (a finger or a stylus) on a touch screen.

The controller 180 controls the operation mode and the screen display of the specific task being executed in the area where the touch gesture is sensed according to the sensed touch gesture (S203). In other words, the control unit 180 stops, backgrounds, or terminates a specific job according to the touch gesture. The control unit 180 registers the specific job in the job management list and hides the area in which the specific job is displayed when the specific job is stopped or switched to the background.

For example, as shown in FIG. 10A, the user inputs a touch gesture diagonally on the preview screen of the camera 121 while simultaneously performing the message function and the camera function. The control unit 180 senses the touch gesture through the sensing unit 140 and recognizes the touch gesture as a task pause command. The control unit 180 stops the operation of the camera 121 and registers the function of the camera 121 in the job management list. Also, the control unit 180 removes the area displayed on the preview screen of the camera 121 from the display screen. In other words, the control unit 180 merges the area closest to one side of the area where the preview screen is displayed, and displays the work screen displayed in the adjacent area on the merged area.

Alternatively, if a symbol as shown in FIG. 10B is input on the calendar screen during the simultaneous execution of the message function and the calendar function, the controller 180 recognizes the command as a job end command and terminates the calendar function being executed. The controller 180 removes the area where the calendar screen is displayed.

Alternatively, if a symbol as shown in FIG. 10C is input on the stopwatch screen while using the message function and the stopwatch function, the control unit 180 recognizes it as a background switching command and switches the stopwatch function from forward to background. At this time, the controller 180 registers the stopwatch function in the job management list and outputs a notification informing that the stopwatch function is switched in the background. Then, the control unit 180 causes the area where the stopwatch screen is displayed to disappear.

As described above, the jobs in the temporary management or background operation are registered in the job management list.

Referring to FIG. 11, the controller 180 executes the multi-task according to the multi-task execution procedure described above (S301).

In operation S302, the controller 180 senses a touch input (e.g., a long touch) input on the boundary of the display screen through the sensing unit 140. [ For example, when a long touch is detected at a lower end of the display screen as shown in FIG. 12A, the controller 180 recognizes the detected touch input as a task manager function execution command.

If the long touch is detected, the control unit 180 executes a task manager function and displays a task list registered in the task management list (S303). That is, the control unit 180 displays a task list that is paused or in the background operation. 12B, the control unit 180 displays the task management list 510 at one end of the display screen. The control unit 180 displays a thumbnail image of the job registered in the job management list 510 or displays an execution icon image of the registered job. Then, the control unit 180 visually displays whether the job is temporarily stopped or background is performed so that the user can know at a glance. For example, the control unit 180 superimposes the icons corresponding to the pause, the background operation, etc. on the thumbnail image or the execution icon image.

If one of the job management lists is selected by the user, the controller 180 resumes the selection job and displays the selected job screen in one of the divided areas (S304 and S305).

The user selects a predetermined job among the jobs in the job management list 510 and drags the selected job to the boundary between the first display area 501 and the second display area 502. [ The controller 180 resumes the selected task according to user input and inserts an execution screen of the selected task between the first display area 501 and the second display area 502 as shown in FIG. In other words, the controller 180 adjusts the sizes of the first display area 501 and the second display area 502 to generate a third display area 503 in which the selected operation screen is inserted.

15 is an example of a screen for job management of the mobile terminal according to the present invention. In the present embodiment, five jobs are simultaneously executed.

First, the control unit 180 displays Job 1, Job 2, and Job 3 among currently executed jobs in different divided areas of the display screen.

If a long touch is detected at one boundary of the display screen during execution of different jobs in each of the divided areas, the controller 180 enters the job management mode (a). Upon entering the job management mode, the controller 180 displays an end icon on the work screen displayed on the display screen. Then, the control unit 180 scrolls the work screen according to the scroll command (b).

If a touch is detected on the end icon located on the work screen, the controller 180 terminates the work and deletes the work screen. For example, when the end icon on the execution screen of task 4 is touched, the control unit 180 terminates the task 4 and closes the execution screen of the task 4. [ Then, the execution screen of job 5 is displayed in the area where the execution screen of job 4 is displayed (c).
