[0098] FIGS. 2A and 2B are diagrams illustrating a screen display method of an electronic device according to various embodiments of the present disclosure.

[0099] Referring to FIG. 2A, a screen in a case where an electronic device including a touch sensitive display displays a plurality of (e.g., two) application execution screens 205 and 206 through split windows not to be superposed on one another (e.g., split windows). For example, a user may additionally execute an IM application in a state where an internet application execution screen is displayed. Then, one screen may be displayed to be split into different execution regions by at least two windows, and through the executions regions, for example, an internet application execution screen 205 and an instant message application execution screen 206 may be provided, respectively. In this way, the electronic device 100 may simultaneously operate a plurality of applications through two or more split screens.

[0100] Referring to FIG. 2B, a screen in a case where an electronic device including a touch sensitive display displays a plurality of (e.g., two) application execution screens 207 and 208 (e.g., popup windows) not to be superposed on one another is illustrated. For example, the user may additionally execute an instant message application in a state where an internet application execution screen is displayed. Then, an instant message application execution screen 208 may be provided through at least a portion of the region where an internet application execution screen 207 is displayed in the state where the internet application execution screen 207 is displayed. For example, the instant message application execution screen 208 may be displayed on at least a portion of the internet application execution screen 207 to be superposed on the at least a portion of the internet application execution screen 207. In this case, in the internet application execution screen 207, a portion corresponding to the instant message application execution screen 208 may be displayed to be hidden by the instant message application execution screen 208 or to penetrate the instant message application execution screen 208.

[0101] According to various embodiments of the present disclosure, in the electronic device 100, whether an application execution screen to be additionally executed is displayed to be superposed on an application execution screen under execution or displayed not to be superposed on the application execution screen under execution may be decided by the user's selection. In addition, according to an embodiment, in the electronic device 100, switching from a split window to a popup window or from a popup window to a split window may be performed based on the user input.

[0102] FIG. 3 is a flowchart illustrating a method of performing switching from a split window to a popup window in an electronic device according to an embodiment of the present disclosure.

[0103] Referring to FIG. 3, in operation 301, under the control of the processor 120, the electronic device 100 displays a plurality of application execution screens (e.g., split windows) on the touch sensitive display not to be superposed on one another.

[0104] In operation 303, under the control of the processor 120, the electronic device 100 displays a separator that separates one or more execution screens (e.g., split windows) displayed on the touch sensitive display not to be superposed on one another, and a controller interface positioned on the separator.

[0105] The separator that separates the one or more screens (e.g., split window) displayed on the touch sensitive display may be a bar-shaped graphical user interface (GUI) element that is positioned between a plurality of split windows. The controller positioned at the center of the separator in default and may be a button type GUI element.

[0106] In operation 305, under the control of the processor 120, the electronic device 100 determines whether a user input is received on the controller interface through the touch sensitive display. When the user input is not received on the controller interface, the electronic device 100 returns to operation 303.

[0107] For example, the user input is a touch input on the controller interface displayed as a GUI element, and may be at least one of a tap input, a long press input, and a drag and short press input which are input by the user through the touch sensitive display. In addition, the user input may be a hovering input.

[0108] When the user input is received on the controller interface, the electronic device 100 proceeds to operation 307. In operation 307, according to the user input under the control of the processor 120, the electronic device 100 switches a split window under activation to a popup window, and displays the popup window on the touch sensitive display. In an embodiment, in operation 307, according to the user input, the electronic device 100 switches an application in a focusing region, to a popup window, and displays the popup window on the touch sensitive display.

[0109] In another embodiment, in operation 307, according to the user input under the control of the processor 120, the electronic device 100 switches one or more execution screens (e.g., split windows) displayed on the touch sensitive display not to be superposed on one another, to an execution screen (e.g., popup window) displayed to be superposed on at least a portion of another execution screen and displays the execution screen on the touch sensitive display. For example, when the user drags following a long press on the controller interface, the split window in the direction of moving the drag input may be switched to a popup window and the popup window may be displayed. At this time, a split window around the popup window may be changed to a background window.

[0110] For example, according to operation 307 of the electronic device 100, the display position of the application execution screen switched from the split window to the popup window under the control of the processor 120 may be positioned at the touch point where an input is performed so as to change the split window to the popup window.

[0111] FIG. 4 is a flowchart illustrating a method of shifting a position of a popup window after a split window is switched to the popup window in an electronic device according to an embodiment of the present disclosure.

[0112] Referring to FIG. 4, in operation 401, under the control of the processor 120, the electronic device 100 displays a plurality of application execution screens (e.g., split windows) on the touch sensitive display not to be superposed on one another. In operation 403, under the control of the processor 120, the electronic device 100 displays a separator that separates one or more execution screens (e.g., split windows) displayed on the touch sensitive display not to be superposed on one another, and a controller interface positioned on the separator.

[0113] In operation 405, under the control of the processor 120, the electronic device 100 determines whether a first user input is received on the controller interface through the touch sensitive display. When the first user input is not received on the controller interface, the electronic device 100 returns to operation 403.

[0114] For example, the user input is a touch input on the controller interface displayed as a GUI element, and may be at least one of a tap input, a long press input, and a drag and short press input which are input by the user through the touch sensitive display. In addition, the user input may be a hovering input.

[0115] When the first user input is received on the controller interface, the electronic device 100 proceeds to operation 407. In operation 407, according to the user first input under the control of the processor 120, the electronic device 100 switches a split window under activation to an execution screen (e.g., a popup window) displayed to be superposed on at least a portion of another execution screen, and displays the execution screen on the touch sensitive display.

[0116] In another embodiment, in operation 407, according to the first user input, the electronic device 100 switches one or more execution screens (e.g., split windows) displayed on the touch sensitive display not to be superposed on one another, to an execution screen (e.g., popup window) displayed to be superposed on at least a portion of another execution screen and displays the execution screen on the touch sensitive display. For example, when the user drags following a long press on the controller interface, a split window in the direction of moving the drag input may be displayed as a popup window. The electronic device 100 may receive the drag input following the long press as the first user input.

[0117] For example, according to operation 407 of the electronic device 100, the display position of the application execution screen switched from the split window to the popup window under the control of the processor 120 may be the same as the position where the first user input is received.

[0118] In operation 409, under the control of the processor 120, the electronic device 100 may determine whether a second user input is received through the touch sensitive display.

[0119] When the second user input is not received, the electronic device 100 returns to operation 407. When the second user input is received, the electronic device 100 proceeds to operation 411. In operation 411, according to the second user input under the control of the processor 120, the electronic device 100 may shift the display position of the popup window on the touch sensitive display. Here, the first user input and the second user input may be different inputs or the same input.

[0120] For example, after the switching to the popup window according to the first user input is performed, when the first user input on the touch sensitive display is released, and then the second user input is input through the touch sensitive display, the electronic device 100 may determine the first user input and the second user input as different inputs.

[0121] However, after the switching to the popup window according to the first user input is performed, when the first user input on the touch sensitive display is not released and a touch input (e.g., drag input) is successively received on the touch sensitive display, the electronic device 100 may determine the first user input and the second user input as the same input. At this time, the electronic device 100 may shift the position of the popup window on the touch sensitive display according to the touch and drag input.

[0122] FIGS. 5A-5D are diagrams illustrating operation screens of performing switching from a split window to a popup window and shifting operation of the popup window in an electronic device according to an embodiment of the present disclosure.

[0123] Referring to FIG. 5A, the electronic device 100 displays a plurality of application execution screens (e.g., a plurality of split window 510a and 510b) on the touch sensitive display not to be superimposed on one another. The electronic device 100 displays a separator 1 that separates the plurality of split window 510a and 510b and a controller interface 2 on the separator 1.

[0124] Referring to FIG. 5B, the electronic device 100 receives first user input 550 or 551 on the controller interface 2 through the touch sensitive display. In an embodiment, the first user input 550 may be a touch input having no directionality. The first user input 550 having no directionality may cause a split window 510b under activation to be switched to an execution screen (e.g., the popup window 520) displayed to be superposed on at least a portion of another execution screen so that the execution screen may be displayed on the touch sensitive display. In another embodiment, the first user input 551 may be a touch input having directionality. The first user input 551 having directionality may cause the split window 510b to be switched to a popup window 520 so that the popup window 520 may be displayed on the touch sensitive display. Among the plurality of split windows, a split window 510a that is not changed to popup window may be extended to the region 510b changed to the popup window and displayed.

[0125] Referring to FIG. 5C, according to a first user input 550, the electronic device 100 switches the split window 510b under activation to a popup window 520 and displays the popup window 520 on the touch sensitive display. The application execution screen, switched from the split window 510b to the popup window 520, may be located at the position where the first user input 550 is received.

[0126] Referring to FIG. 5D, the electronic device 100 may shift the position of the popup window 520 according to the second user input 560.

[0127] For example, the first and second user inputs may be touch inputs on the controller interface displayed as a GUI element, and may be at least one of a tap input, a long press input, a drag and short press input which are input by the user through touch sensitive display. In addition, the first and second user inputs may be hovering inputs.

[0128] FIGS. 6A-6C are diagrams illustrating operation screens of performing switching from a split window to a popup window in an electronic device according to an embodiment of the present disclosure.

[0129] Referring to FIG. 6A, the electronic device 100 displays a plurality of application execution screens (e.g., a plurality of split windows 610a, 610b, 610c, and 610d)) not to be superposed on one another on the touch sensitive display. The electronic device 100 displays a separator 1 that separates the plurality of split windows 610a, 610b, 610c, and 610d and a controller interface 2 positioned at the center of the separator 1.

[0130] Referring to FIG. 6B, when a user input 650 directed to the application execution screen 610b of the right upper end among the plurality of application execution screens 610a, 610b, 610c, and 610d on the controller interface 2 through the touch sensitive display, the electronic device 100 switches the split window 610c under activation to a popup window 620 and displays the popup window 620 on the touch sensitive display. The application execution screen 610b of the right upper end is extended to the split window 610c region changed to an execution screen (e.g., popup window 620) displayed to be superposed on at least a portion of the split window 610c.

[0131] In another embodiment, when the user shifts the user input 650 toward the application execution screen 610b of the right upper end, the split window 610b in the direction of shifting the user input 650 may be displayed as the popup window 620. At this time, the split window 610c around the popup window 620 may be changed to a background window.

[0132] Referring to FIG. 6C, when a user input 660 directed toward the application execution screen 610d of the left lower end among the plurality of application execution screens 610a, 610b, 610c, and 610d is received on the controller interface 2 through the touch sensitive display, the electronic device 100 switches the split window 610c under activation to a popup window 620 and displays the popup window 620 on the touch sensitive display. The application execution screen 610d of the left lower end is extended to the split window 610c region changed to the popup window 620.

[0133] Referring to FIG., when the user shifts the user input 660 toward the application execution screen 610d of the left lower end, the split window 610d in the direction of shifting the user input 660 may be displayed as a popup window 620. At this time, the split window 610c around the popup window 620 may be changed to a background window.

[0134] FIG. 7 is a flowchart illustrating a method of performing switching from a popup window to a split window in an electronic device according to an embodiment of the present disclosure.

[0135] Referring to FIG. 7, in operation 701, the electronic device 100 displays at least one application execution screen by an execution screen (e.g., popup window) displayed to be superimposed on at least a portion on the touch sensitive display under the control of the processor 120.

[0136] For example, in operation 701 of the electronic device 100, at least one popup window, in which an application execution screen is displayed, may be displayed on the touch sensitive display.

[0137] In operation 703, under the control of the processor 120, the electronic device 100 determines whether a user input is received through the touch sensitive display. In an embodiment, the user input is a user input for shifting the popup window, which may be a touch and drag input on the popup window. When the touch and drag input is received on the GUI element displayed as the popup window, the electronic device 100 may display the shift of the popup window on the touch sensitive display.

[0138] When the user input is not received, the electronic device 100 returns to operation 701, and when the user input is received, the electronic device 100 proceeds to operation 705.

[0139] In operation 705, the electronic device 100 shifts and displays the popup window on the touch sensitive display according the user input under the control of the processor 120.

[0140] In operation 707, the electronic device 100 determines whether an execution screen (e.g., popup window) displayed to be superposed on at least a portion of a shifted region is shifted to a switching region (e.g., docking region), in which the execution screen may be switched to one or more execution screens (e.g., split windows) displayed on the touch sensitive display not to be superposed on one another. For example, the docking region may be a boundary region of the touch sensitive display. The docking region may be formed in a predetermined region of the boundary of the touch sensitive display. The docking region may be formed in a predetermined region at upper, lower, left, and right sides of the touch sensitive display.

[0141] When the shifted popup window is not shifted to the docking region, the electronic device 100 returns to operation 705, and when it is determined that the shifted popup window is shifted to the docking region, the electronic device 100 proceeds to operation 709.

[0142] In operation 709, under the control of the processor 120, the electronic device 100 displays a docking guide on the touch sensitive display. The docking guide is a GUI element that indicates the shifted popup window is positioned in the docking region and notifies in advance the user of a position where the popup window is to be changed to split window. For example, when the shifted popup window is positioned in the docking region, the electronic device 100 may display the popup window in a state where the popup window is changed to a translucent or transparent split window.

[0143] In operation 711, under the control of the processor 120, the electronic device 100 determines whether the popup window shifted to the docking region has stopped shift for a predetermined length of time. In other words, in operation 711, under the control of the processor 120, the electronic device 100 determines whether the shifted popup window has stayed in the docking region for the predetermined length of time.

[0144] When it is determined that the shifted popup window has not stayed in the docketing region for the predetermined length of time, the displayed docking guide disappears and the electronic device 100 returns to operation 705. When it is determined that the popup window has stayed in the docking region for the predetermined length of time, the electronic device 100 proceeds to operation 713.

[0145] In operation 713, under the control of the processor 120, the electronic device 100 switches the popup window to a split window, and displays the split window on the touch sensitive display. For example, when the shifted popup window has stayed in the docking region for the predetermined length of time, the electronic device 100 may switch the docking guide from a form of a translucent or transparent split window to a form of an opaque split window, and display the split window.

[0146] FIGS. 8A-8D are diagrams illustrating operation screens of performing switching from a popup window to a split window in an electronic device according to an embodiment of the present disclosure.

[0147] Referring to FIG. 8A, the electronic device 100 may display a first application execution screen as a whole screen 810a on the touch sensitive display, and display a second application execution screen as an execution screen (e.g., popup window 810b) displayed to be superposed on at least a portion of the whole screen 810a. In the upper and lower boundary regions of the touch sensitive display of the electronic device 100, there are switching regions (e.g., docking regions 820a and 820b), in which an execution screen (e.g., popup window) displayed to be superposed on at least a non-displayed portion may be switched to one or more execution screens (e.g., split windows) displayed on the touch sensitive display not to be imposed on one another.

[0148] Referring to FIG. 8B, the popup window 810b may be shifted to the docking region 820a.

[0149] Referring to FIG. 8C, when the popup window 810b is positioned in the docking region 820a, a docking guide 830 may be displayed. When the docking guide 830 is displayed, a separator 1 and a controller interface 2 may be displayed together with the docking guide 830. The docking guide 830 is a GUI element that indicates that the shifted popup window 810b is positioned in the docking region 820a and notifies in advance the user of a point where the popup window 810b is to be changed to a split window 840. For example, when the shifted popup window 810b is positioned in the docking region 820a, the electronic device 100 may change the popup window 810b to one or more translucent or transparent execution screens (e.g., split window 830) displayed not to be superposed on one another, and display the execution screens on the touch sensitive display.

[0150] Referring to FIG. 8D, when the shifted popup window 810b has stayed in the docking region 820a for a predetermined length of time, the docking guide 830 in the form of the translucent or transparent split window may be shifted to an opaque split window 840 so that the opaque split window 840 may be displayed.

[0151] When the shifted popup window 810b has not stayed in the docking region 820a for the predetermined length of time, the displayed docking guide disappears and switching from the screen of FIG. 8C to the screen of FIG. 8B is performed.

In the upper and lower boundary regions of the electronic device 100, there are non-displayed docking regions 920a and 920b.

[0154] Referring to FIG. 9B, the popup window 910c may be shifted to the docking region 920a according to a user input.

[0155] Referring to FIG. 9C, when the shifted popup window 910c is positioned in the docking region 920a, a docking guide 930 may be displayed. The docking guide 930 is a GUI element that indicates that the shifted popup window 910c is positioned in the docking region 920a and notifies the use of the position where the popup window 910c is to be changed to a split window 940 of FIG. 9D. For example, when the shifted popup window 910c is positioned in the docking region 920a, the electronic device 100 may change the popup window 910c to a translucent or transparent split window 930 and display the split window 930.

[0156] Referring to FIG. 9D, when the shifted popup window 910c has stayed in the docking region 920a for a predetermined length of time, the electronic device 100 may switch the docking guide 930 in the form of the translucent or transparent split window to an opaque split window 940 and display the split window 940. The region of the switched split window 940 is the same as that of the first split window 910a, and the first application that has been executed in the first split window 910a may be terminated or executed in the background of the switched split window 940. In the foreground of the switched split window 940, a third application execution screen is displayed.

[0157] When the shifted popup window 910c has not stayed in the docking region 920a for the predetermined length of time, the displayed docking guide disappears and the screen of FIG. 9C is switched to the screen of FIG. 9B.

[0158] FIG. 10 is a flowchart illustrating a method of performing switching between a split window and an icon in an electronic device according to an embodiment of the present disclosure.

[0159] Referring to FIG. 10, in operation 1001, under the control of the processor 120, the electronic device 100 displays a plurality of application execution screens (e.g., a plurality of split windows)) on the touch sensitive display not to be superposed on one another.

[0160] In operation 1003, under the control of the processor 120, the electronic device 100 displays a separator that separates the plurality of application execution screens (e.g., the plurality of split windows) not to be superposed on one another, and a controller interface positioned on the separator on the touch sensitive display.

[0161] In operation 1005, under the control of the processor 120, the electronic device 100 determines whether a first user input is received on the controller interface through the touch sensitive display. When the first user input is not received on the controller interface, the electronic device 100 returns to operation 1003.

[0162] For example, the first user input is a touch input on the controller interface displayed as a GUI element, and may be a touch and drag input that is input by the user through the touch sensitive display. In another embodiment, the first user input may be a hovering input.

[0163] When the first user input is received on the controller interface, the electronic device 100 may proceed to operation 1007. In operation 1007, according to the first user input under the control of the processor 120, the electronic device 100 switches the split window to an icon, and displays the icon on the touch sensitive display. The icon (graphical symbol) may be a representative image of an application which is being executed on a split window.

[0164] For example, when the first user input (e.g., touch and drag) is received on the controller interface, the split window is gradually reduced in size, and when the split window is shifted by a predetermined distance or more, the split window disappears and is displayed as an icon. The position where the icon is displayed may be displayed in a shifting direction of the first user input and the lower end of the touch sensitive display.

[0165] In operation 1009, under the control of the processor 120, the electronic device 100 determines whether a second user input for the icon is received through the touch sensitive display.

[0166] When the second user input for the icon is not received, the electronic device 100 returns to operation 1007. When the second user input for the icon is received, the electronic device 100 proceeds to operation 1011.

[0167] In operation 1011, according to the second user input under the control of the processor 120, the electronic device 100 may display an application execution screen corresponding to the icon by a split window.

[0168] For example, the second user input is a touch input on the icon displayed as a GUI element, and may be at least one of a tap input, a long press input, and a drag and short press input which are input by the user through the touch sensitive display. In addition, the second user input may be a hovering input.

[0169] FIGS. 11A-11C are diagrams illustrating operation screens of performing switching between a split window and an icon in an electronic device according to an embodiment of the present disclosure.

[0170] Referring to FIG. 11A, the electronic device 100 displays a plurality of application execution screens (e.g., a plurality of split windows 1110a and 1110b) on the touch sensitive display not to be superposed on one another. The electronic device 100 displays a separator 1 that separates the plurality of split windows 1110a and 1110b, and a controller interface 2 positioned on the separator 1.

[0171] Referring to FIG. 11B, the electronic device 100 receives a first user input 1130 on the controller interface 2 through the touch sensitive display. The first user input 1130 is a touch input on the controller interface displayed as a GUI element, and may be a touch and drag input that is input by the user through the touch sensitive display. In another embodiment, the first user input may be a hovering input.

[0172] Referring to FIG. 11C, the electronic device 100 switches a split window 1110b, which is being activated according to the first user input 1130 or is in the drag input direction, to an icon 1120 and displays the icon 1120 on the touch sensitive display. The icon (graphical symbol) may be a representative image of an application that is being executed in the split window.

[0173] For example, when the first user input (e.g., touch and drag input 1130) is received on the controller interface, the electronic device 100 may gradually reduce the size of the split window 1110b, and when the first user input is shifted by a predetermined distance or more, the split window may disappear and the icon 1120 may be displayed. The position where the icon is displayed may be in the shifting direction of the first user input 1130, or the icon may be displayed on the lower end of the touch sensitive display. At this time, the split window 1110a, in which the first user input 1130 is not received, may be switched to a whole screen and the whole screen may be displayed.

[0174] In another embodiment, when a second user input 1140 for the icon 1120, an application related to the icon 1120 may be executed and displayed on the split window 1110b as in the screen of FIG. 11A.

[0175] FIG. 12 is a flowchart illustrating a switching method between a split window and an icon in an electronic device according to an embodiment of the present disclosure.

[0176] Referring to FIG. 12, in operation 1201, under the control of the processor 120, the electronic device 100 may display at least one icon representing an application on the touch sensitive display.

[0177] In operation 1203, under the control of the processor 120, the electronic device 100 determines whether a user input is received through the touch sensitive display. In an embodiment, the user input is a user input for shifting the icon that may be a touch and drag input for the icon. When a touch and drag input for a GUI element displayed as the icon, the electronic device 100 may display shift of the icon on the touch sensitive display.

[0178] When the user input is not received, the electronic device 100 returns to operation 1201, and when the user input is received, the electronic device 100 proceeds to operation 1205.

[0179] In operation 1205, according to the user input under the control of the processor 120, the electronic device 100 shifts and displays the icon on the touch sensitive display.

[0180] In operation 1207, the electronic device 100 determines whether the shifted icon is shifted to a switching region (e.g., docking region), in which one or more shifted icons may be switched to one or more execution screens (e.g., split window) displayed on the touch sensitive display not to be superimposed on one another. For example, the docking region may be a boundary region of the touch sensitive display. The docking region may be formed in a predetermined region of a boundary of the touch sensitive display. The docking region may be formed in a predetermined region at the upper, lower, left, or right side of the touch sensitive display.

[0181] When the shifted icon is not shifted to the docking region, the electronic device 100 returns to operation 1205, and when it is determined that the shifted icon is shifted to the docking region, the electronic device 100 proceeds to operation 1209.

[0182] In operation 1209, under the control of the processor 120, the electronic device 100 displays a docking guide on the touch sensitive display. The docking guide is a GUI element that indicates that the shifted icon is positioned in the docking region, and notifies, in advance, the user of the position where the icon is to be changed to a split window. For example, when the shifted icon is positioned in the docking region, the electronic device 100 may change the icon to a translucent or transparent split window and display the translucent or transparent split window.

[0183] In operation 1211, under the control of the processor 120, the electronic device 100 determines whether the icon shifted to the docking region has stopped the shift for a predetermined length of time. In other words, in operation 1211, under the control of the processor 120, the electronic device 100 determines whether the shifted icon has stayed in the docking region for the predetermined length of time.

[0184] When it is determined that the shifted icon has not stayed in the docking region for the predetermined length of time, the displayed docking guide disappears and the electronic device 100 returns to operation 1205. When it is determined the shifted icon has stayed in the docking region for the predetermined length of time, the electronic device 100 proceeds to operation 1213.

[0185] In operation 1213, under the control of the processor 120, the electronic device 100 switches the icon to a split window and displays the split window on the touch sensitive display. For example, when the shifted icon has stayed in the docking region for the predetermined length of time, the electronic device 100 may convert the docking guide in the form of a translucent or transparent split window in the form of an opaque split window, and display the split window.

[0186] FIG. 13 is a flowchart illustrating event notification occurrence of an application displayed as an icon in an electronic device according to an embodiment of the present disclosure.

[0187] Referring to FIG. 13, in operation 1301, the electronic device 100 displays at least one icon that represents an application on the touch sensitive display under the control of the processor 120.

[0188] In operation 1303, the electronic device 100 determines whether an event has occurred in the application displayed as the icon. The event may be, for example, message reception, push event occurrence, alarm, or notification.

[0189] When it is determined that no event has occurred, the electronic device 100 returns to operation 1301. When it is determined that an event has occurred, the electronic device 100 proceeds to operation 1305.

[0190] In operation 1305, the electronic device 100 displays event occurrence on the touch sensitive display under the control of the processor 120. For example, when the event occurs, the electronic device 100 may notifies the user of the event occurrence in the manner of displaying the icon to flicker or displaying event contents in a given region. When the event contents are displayed in the given region, the event contents may be displayed as a translucent or transparent dimming window.

[0249] FIG. 23 is a flowchart illustrating a window switching method in an electronic device 100 according to an embodiment of the present disclosure.

[0250] Referring to FIG. 23, in operation 2301, the electronic device 100 displays a first application execution screen on the touch sensitive display under the control of the processor 120.

[0251] In operation 2303, the electronic device 100 determines whether there is a first user input through the touch sensitive display. When there is no first user input, the electronic device 100 returns to operation 2301.

[0252] When there is the first user input, in operation 2305, the electronic device 100 determines whether the first user input is released after the first user input was input to a first point on the touch sensitive display.

[0253] When it is determined that the first user input is released after the first user input was input to the first point, in operation 2313, the electronic device 100 converts the first application execution screen to a popup window screen and displays the popup window screen. In operation 2315, the electronic device 100 determines whether there is a second user input through the touch sensitive display. When there is no second user input, the electronic device 100 returns to operation 2313, and displays an execution screen (e.g., a popup window) displayed to be superposed on at least a portion. When there is the second user input, the electronic device 100 proceeds to operation 2309.

[0254] When it is determined that the first user input is not released after the first user input was input to the first point, in operation 2307, the electronic device 100 determines whether the first user input is released after the first user input was input to a second point via the first point on the touch sensitive display.

[0255] When the first user input is released without having been input to the second point via the first point, the electronic device 100 returns to operation 2313 and displays the first application execution screen as an execution screen (e.g., a popup window) displayed to be superposed on at least a portion of the.

[0256] The first point is positioned in a direction oriented toward a diagonal corner from any one of four corners of a whole screen or a split window according to the first user input, and the second point is positioned perpendicular to one of the corners that are not occupied by the popup window from the first point. The shift direction of the second user input is directed perpendicular to one of the corners that are not occupied by the popup window.

[0257] When it is determined that the first user input is released after the first user input was input to the second point via the first point or it is determined that there is the second user input, in operation 2309, the electronic device 100 determines whether there is a second application that is being executed in the background under the control of the processor 120.

[0258] When there is the second application that is being executed in the background, in operation 2311, the electronic device 100 displays the first application execution screen and the second application execution screen on the touch sensitive display as split windows under the control of the processor 120.

[0259] When there is no second application which is being executed in the background, in operation 2317, the electronic device 100 displays, under the control of the processor 120, the first application as one or more execution screens (e.g., split window) displayed on the touch sensitive display not to be superposed on one another, and displays an application list in the split window where the first application is not displayed.

[0260] In operation 2319, under the control of the processor 120, the electronic device 100 determines whether there is a user input that selects an application in the application list through the touch sensitive display. When there is no user input related to application selection, the electronic device 100 returns to operation 2317.

[0261] When there is the user input related to application selection, in operation 2321, under the control of the processor 120, the electronic device 100 additionally displays the selected application execution screen as a split window on the touch sensitive display.

[0262] FIGS. 24A to 24E is a diagram illustrating operation screens of performing window switching in the electronic device 100 according to another embodiment of the present disclosure.

[0263] Referring to FIG. 24A, the electronic device 100 may display a first application execution screen as a whole screen 2410 on the touch sensitive display.

[0264] Referring to FIG. 24B, when the first user input 2420 is released after the first user input was shifted to the first point p1, the electronic device 100 may display the first application execution screen as a popup window 2420 on the touch sensitive display.

[0265] Referring to FIG. 24C, when the first user input 2420 is released after the first user input was shifted to the second point P2 via the first point p1, the electronic device 100 may display the first application execution screen as a split window 2421 on the touch sensitive display. At this time, when there is a second application which is being executed in the background, the second application execution screen is displayed on the touch sensitive display as a split window 2431.

[0266] Referring to FIG. 24D, when there is no second application that is being executed in the background, the electronic device 100 displays first application execution screen as the split window 2421 on the touch sensitive display, and displays the application list in the remaining split window 2432.

[0267] Referring to FIG. 24E, when one application is selected in the application list, the selected application execution screen may be displayed as a split window 2433.
