3 is a flowchart illustrating a multi-task execution method of a mobile terminal according to an 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 a standby screen (home screen), the controller 180 executes a message application program. The controller 180 enters a message composition mode for message creation according to a user input and outputs a message composition screen to the display unit 151.

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

The multi-task command input method may use any one of the following methods. First, when a key to which a multi task (multitask) is assigned among the keys provided in the user input unit 130 is pressed, the controller 180 recognizes the multi task command. Second, as shown in FIG. 4, while performing message writing, a long touch is sensed at one point A of one boundary of the message writing screen, and after the long touch is detected, the touch point is subsequently released without the touch release. Detects a drag to a point B of the boundary parallel to the one side boundary, the controller 180 recognizes the multi-task request. Third, when a drag is input from one side boundary of the display screen to the other side boundary facing the one side boundary, the sensing unit 140 detects this drag. The controller 180 calculates a width of a line drawn by the sensed drag input. If the width of the drag line is less than or equal to the threshold, the controller 180 recognizes the drag input as a multi-task request. That is, the controller 180 recognizes the multi-task command or the general drag command according to the contact area between the pointing means and the display screen. For example, when a drag of a line to a fingernail is input, the controller 180 recognizes a multi-task command, and when a drag having a predetermined line width is input by a fingertip, the controller 180 performs a general drag (object movement, handwriting input, etc.). To be recognized.

Upon receiving the multi-task command, the controller 180 divides the display screen (S103). In this case, when a drag is input on the display area on which the currently executing work screen is displayed, the controller 180 divides the display area based on the point where the drag input is detected. Alternatively, the controller 180 may divide the display screen according to preset information.

When the screen is divided, the controller 180 displays execution information (execution screen, task screen) of the predetermined task in any one of the divided regions, and displays a task list capable of multiple tasks in any other region. (S104). That is, the controller 180 divides the display area on which one job screen being executed is displayed into a first display area and a second display area based on a multi-task command, and displays the running job screen on the first display area. In the second display area, a list of applications that can be multitasked is displayed.

When any 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 and S106). For example, when a job different from the running job is selected from the list of application programs displayed on the second display area, the controller 180 executes the selected job and displays an execution screen (selection job screen) of the selected job in the second display area. Mark on.

5A and 5B illustrate an example of a process of executing multiple tasks using 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 displaying an operation state and data according to the execution of a predetermined job, and the predetermined job is executed. If so, the screen of the executed job is displayed on the information display area 300. For example, when a user selects a message function to compose a message, the controller 180 executes the message function and displays a message composition screen on the information display area 300.

When a multi-task command is input on the information display area 300 on which the message creation screen is displayed, the controller 180 controls the information display area 300 according to the multi-task command as shown in FIG. 310 is divided into a second display area 320. In addition, the controller 180 displays the running message creation screen on the first display area 310 and displays a list of application programs (menu list) capable of multiple operations on the second display area 320.

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

6A to 6E illustrate another example of a process in which a mobile terminal according to the present invention executes multiple tasks.

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

When the drag 321 is input from the point A to the point B of the boundary of the display screen on which the message creation screen is displayed, the controller 180 removes the display screen 330 based on the position where the drag is input as shown in FIG. The display unit 331 is divided into a first display area 331 and a second display area 332. The controller 180 displays a message creation screen on the first display area 331 and displays a list of application programs (jobs) on the second display area 332.

According to the above-described procedure shown in FIG. 3, the controller 180 divides the display screen into at least two or more regions, and executes different tasks in each of the divided regions to display the execution screen (S201).

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

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

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

Alternatively, if a symbol as shown in FIG. 10B is input on the calendar screen while simultaneously executing a message function and a calendar function, the controller 180 recognizes as a job end command and terminates the currently executed calendar function. The controller 180 removes an 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 controller 180 recognizes the background switching command and switches the stopwatch function from forward to background. At this time, the controller 180 registers the stopwatch function in the task management list and outputs a notification indicating that the stopwatch function is switched to the background. In addition, the controller 180 makes the area where the stopwatch screen is displayed disappear.

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

For example, as illustrated in FIG. 12A, when a long touch is detected at a lower point of the display screen, the controller 180 recognizes the detected touch input as a task manager function execution command.

When the long touch is detected, the controller 180 executes a task manager function and displays a task list registered in the task management list (S303). That is, the controller 180 displays a list of jobs that are paused or are in the background. According to FIG. 12B, the controller 180 displays the task management list 510 at one end of the display screen. The controller 180 displays a thumbnail image of a job registered in the job management list 510 or displays an execution icon image of a registered job. In addition, the controller 180 visually displays the user so that the user can know at a glance whether the job is paused or in the background. For example, the controller 180 displays an icon corresponding to a pause or a background operation, respectively, on the thumbnail image or the execution icon image.

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