DISPLAY DEVICE AND METHOD OF CONTROLLING THE SAME

[0001] This application claims the benefit under 35 U.S.C. §119(e) of a U.S. Provisional application filed on Dec. 6, 2012 in the U.S. Patent and Trademark Office and assigned Ser. No. 61/734,099, and under 35 U.S.C. §119(a) of Korean patent applications filed on Dec. 31, 2012 in the Korean Intellectual Property Office and assigned Serial Nos. 10-2012-0158413, 10-2012-0158422, and 10-2012-0158391, the entire disclosures of each of which is hereby incorporated by reference.

[0002] The present disclosure relates to a display device and a method of controlling the same. More particularly, the present disclosure relates to a display device which controls a display of a window in which an application is executed, and a method of controlling the same.

[0003] A desktop computer has at least one display device (for example, a monitor). A mobile device (for example, a mobile phone, a smart phone, or a tablet PC) using a touch screen typically has one display device.

[0004] A user of the desktop computer may divide a screen of the display device according to a working environment (for example, horizontally or vertically divide the screen while displaying a plurality of windows). When a web browser is executed, the user can move in an up or down direction of the web page by using a page up button or a page down button arranged in a keyboard. When the user uses a mouse instead of the keyboard, the user can move in the up or down direction of the web page by selecting a scroll bar located in a side part of the web page by using a cursor. Further, the user can move in the up or down direction of the web page by selecting a top button displayed as a text or an icon located in a bottom part of the web page.

[0005] The mobile device has a smaller size of the displayed screen as compared to the desktop computer and has a limitation in an input. It is accordingly difficult for the user to divide the screen of the mobile device.

[0006] Further, the mobile device can execute various applications such as basic applications produced by a manufacturer of the mobile device and then installed in the mobile device and additional applications downloaded from an application store through the Internet. The additional applications may be developed by general users and registered in an application store. Accordingly, anyone can freely sell applications to users of the mobile device through the application selling site. Accordingly, upwards of hundreds of thousands of free or paid applications are provided to the current mobile devices according to types of mobile devices.

[0007] Although various applications which simulate consumers' curiosity and satisfy consumers' demands are provided to the mobile device, since the mobile device is provided to have a portable size, it has a limitation in a size and a User Interface (UI) thereof. Accordingly, the users feel inconvenience in executing a plurality of applications in the mobile device. For example, when one application is executed in the mobile device, the application is displayed in an entire display area. Further, when the user desires to execute another application, the user should first end the currently executed application and then select an execution key for executing the desired application. In order to execute several applications in the mobile device, processes of executing and ending the respective applications should be repeated, which is cumbersome. Further, a method of simultaneously executing the several applications in the mobile device has not been provided.

[0008] A mobile device of the related art does not define an execution space designated for each application. Accordingly, in switching an application screen which is being executed to another application screen, the conventional mobile device is required to end the application which is being executed, return to a home screen, and then execute another application in the home screen. Further, when sharing data between applications, the conventional mobile device is required to copy data from one application, return to a home screen, and then execute another application to paste the data.

[0009] The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

[0010] Aspects of the present disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a display device that shares data in an application execution space, and a method of controlling the same.

[0096] FIGS. 2A and 2B illustrate an application execution space according to the present disclosure.

[0097] Referring to FIG. 2A, the display device 100 may define an application execution space 200 which is a virtual area including an area of the touch screen 190. The display device 100 may set coordinates with respect to the entire application execution space 200. For example, the display device 100 may set coordinates having a size of 900×900 with respect to the entire application execution space 200. A coordinate value of an x axis may be a value from −300 to 600 and a coordinate value of a y axis may be a value from −300 to 600.

[0098] The display device 100 may divide the application execution space 200 into nine sub spaces 201 to 209 and define the nine sub spaces 201 to 209. The sub spaces 201 to 209 refer to spaces in which a window executing an application can be arranged, and a plurality of windows as well as one window can be arranged in one sub space of the display device 100. The display device 100 may define a first sub space 201 in which a value from −300 to 0 is set with respect to the x axis and a value from 0 to 300 is set with respect to the y axis. The display device 100 may set a coordinate value with respect to each sub space. A result of the setting may be as shown in Table 1.

TABLE 1
Sub space	Range of an x axis	Range of a y axis
index	coordinate value	coordinate value
1	−300~0	300~600
2	0~300	300~600
3	300~600	300~600
4	−300~0	0~300
5	0~300	0~300
6	300~600	0~300
7	−300~0	−300~0
8	0~300	−300~0
9	300~600	−300~0

[0099] At least one window executing an application may be arranged within each of the sub spaces 2001 to 209. For example, a first window 210 executing an application B may be arranged in the second sub space 202. A second window 211 executing an application G and a third window 212 executing an application H may be arranged in the fourth sub space 204. A fourth window 213 executing an application A may be arranged in the fifth sub space 205 through an entire screen. A fifth window 214 executing an application C and a sixth window 215 executing an application D may be arranged in left and right sides of the sixth sub space 206 in a split mode, respectively. A seventh window 216 executing an application E and an eighth window 217 executing an application F may be arranged in upper and lower sides of the eighth sub space 207 in the split mode, respectively. The display device 100 may arrange at least one window executing an application in each of the sub spaces 201 to 209.

[0100] The display device 100 may physically display one of the sub spaces 201 to 209, for example, the fifth sub space 205 on the touch screen 190. The display device 100 may display, for example, the fourth window 213 executing the application A of the fifth sub space 205.

[0101] The display device 100 may display another sub space based on an input display change gesture. For example, when a user inputs a rightward drag gesture into the touch screen 190, the display device 100 may display the sixth sub space 206 on the touch screen 190. The controller 110 may reset an x axis coordinate value of an area physically displayed on the touch screen 190 to a value from 0 to 300 and a y axis coordinate value to a value from 0 to 300, and also reset the remaining sub space coordinates based on the reset values. A configuration of changing and then displaying the sub spaces is described below.

[0102] The controller 110 may manage each of the sub spaces 201 to 209 in the unit of pages. For example, when the user inputs the display change gesture from the fifth sub space 205 to the sixth sub space 206 as described above, the controller 110 changes the displayed fifth sub space 205 into the sixth sub space 206 in the unit of sub spaces, (i.e., in the unit of pages). The controller 110 may simultaneously display a part of the fifth sub space 205 and a part of the sixth sub space 206 to animate the display change from the fifth sub space 205 to the sixth sub space 206 while changing the display, but does not display a mixed image of the part of the fifth sub space 205 and the part of the sixth space 206.

[0103] The controller 110 may manage each of the sub spaces 201 to 209 in the unit of pixels as opposed to pages. For example, when the user inputs the display change gesture from the fifth sub space 205 to the sixth sub space 206, the controller 110 may change the displayed fifth sub space 205 into the sixth sub space 206 in the unit of pixels. The controller 110 may change a range of the x axis of the physically displayed coordinate one by one such that the range is changed from (0, 300) to (1, 301), (2, 302), and so forth. As described above, the mixed image of the part of the fifth sub space 205 and the part of the sixth sub space 206 may be displayed on the touch screen 190.

[0104] Although coordinates having a size of 900×900 are set with respect to the entire application execution space 200, a coordinate value is set to a value from −300 to 600 with respect to the x axis, and a value frame −300 to 600 is set with respect to the y axis in FIG. 2A as an example, the coordinate value of the application execution space 200 can be set to another value. Further, in the application execution space 200 according to the present disclosure, a size of each sub space, for example, the page may be determined according to a size of the physical display area, for example, the touch screen 190.

[0105] FIG. 2B illustrates a case where a size of a physical display area of an application execution space according to another embodiment of the present disclosure is 1024×640.

[0106] Referring to FIG. 2B, one page may have a maximum size of 1024×640 as indicated by a reference numeral 250. At least one page is included in + and − directions of the x axis based on (0, 0), and at least one page is included in + and − directions of the y axis. Although FIG. 2B illustrates a maximum page size of 1024×640 as an example, a size of the application execution window may be larger or smaller according to a size of the display area. The size of the page has no limitation as long as it does not exceed a maximum size, and at least one application execution window may be arranged on each page.

[0107] FIG. 3 illustrates a home execution space and an application execution space according to an embodiment of the present disclosure.

[0108] Referring to FIG. 3, the terminal 100 may define the home execution space 300 and the application execution space 200 as divided areas separated from each other. For example, the terminal 100 may set a coordinate with respect to the application execution space 200 by using a virtual space. As described in FIGS. 2A and 2B, the terminal 100 may set the coordinate having a predetermined size with respect to the application execution space 200, and a coordinate value (x, y) thereof may be set to be separated from the home execution space 300.

[0109] The home execution space 300 may be a space where a launcher related to the home of the terminal 100 is executed and a launcher screen 310 according to the execution of the launcher is generated. The launcher refers to an application associated with the home and corresponds to a home application different from a general application. For example, when the terminal 100 is turned on, the launcher may be executed in the home execution space 300 and the launcher screen 310 by the launcher is generated to be displayed on the touch screen 190. For example, the launcher screen 310 may include a home screen, and a desktop (background screen), a tray including shortcut icons for executing frequently used applications, various menus, or a thumbnail image of an executable application may be displayed on the home screen. The home execution space 300 may be defined as one logical space and displayed by a plurality of views 301 to 304 according to a size of the physical display area, (i.e., the touch screen) as necessary.

[0110] The application execution space 200 is a space where an application is executed and an application execution window according to the execution of the application is generated. The application may include a game application, a video reproduction application, a map application, a memo application, a broadcasting application, a sports support application, a payment application, a picture editing application and the like, but the application according to present disclosure is not limited thereto.

[0111] The application execution space 200 may include a plurality of sub spaces, for example, a plurality of pages 221 to 229 which can independently execute a plurality of applications App#01 to App#n or execute two or more applications, and the pages may be added or deleted in the application execution space 200. A size of each of the pages may be the same as the size of the display area, that is, the touch screen 190. Each of the plurality of pages 221 to 229 may display one application execution window or two or more application execution windows, (i.e., a multi window). As illustrated in FIG. 3, three application execution windows 221-1, 221-2, and 222-3 may be displayed on one page 221, two application execution windows 222-1 and 222-3 may be displayed on one page 222, and one application execution window 223-1 may be displayed on one page 223. The application execution space 200 may include the desktop (background screen) like the home execution space 300 or the desktop may be set according to a selection by the user.

[0112] According to an embodiment of the present disclosure, the terminal 100 can display switching between pages in the application execution space 200, switching between views in the home execution space 300, and switching from a page of the application execution space 200 to a view of the home execution space 300.

[0113] According to an embodiment of the present disclosure, the controller 110 may include a framework to process the application execution space 200 and the home execution space 300.

[0114] FIG. 4 illustrates a concept describing an application framework according to the present disclosure.

[0115] Referring to FIG. 4, an application framework 400 processes the application execution space 200 and the home execution space 300 according to a corresponding event based on an event input by the user. The application framework 400 may include an event handler 410, an application manager module 420, and a window manager module 430.

[0116] When the user inputs a display change event in the application execution space 200, the event handler 410 detects the corresponding display change event. For example, when the display change event is for scrolling a screen, the event handler 410 may generate a space moving event by a scrolled delta and transmit the generated space moving event to the application manager module 420. The application manager module 420 serves as an interface for transmitting information transmitted from the application to the window manager module 430. For example, when the user inputs a predetermined user gesture, such as a flick in an application mode, the application manger module 420 transmits movement length information for moving the application by a movement length corresponding to the input flick to the window manager module 430.

[0117] The application manager module 420 may directly approach the window manager module 430 to transmit data received from the application and to receive a result thereof from the application. For example, the application manager module 420 transmits movement length information received from the event handler 410 to the window manager module 430 to indicate that the application has been moved, and allows the window manager module 430 to move the application by a movement length.

[0118] The window manager module 430 corresponds to an object managing information on a position to which the application has been moved, which manages a page and information on a position where each application is executed.

[0119] A display operation using the home execution space 300 and the application execution space 200 can be performed through the above described application framework 400.

[0120] FIG. 5A is a diagram describing a method of executing an application in a home execution space according to an embodiment of the present disclosure, and FIG. 5B is a flowchart illustrating a process of executing an application in a home execution space according to an embodiment of the present disclosure.

[0121] Referring to FIGS. 5A and 5B, the display device 100 determines whether an application execution event by the user is generated in a state where the launcher screen 310 using the home execution space 300 is displayed in operation S510.

[0122] The display device 100 may execute the application according to the generation of the application execution event by the user in the state where the launcher screen 310 using the home execution space 300 is displayed. The launcher screen 310 may have one view corresponding to a size of the touch screen 190 or may be divided into a plurality of views L1, L2, and L3 when the launcher screen 310 is larger than the touch screen 190. Only one view L1 of the plurality of views may be displayed on the touch screen 190.

[0123] The user may generate the application execution event by using an icon for executing the application in the view L1 of the launcher screen 130, by selecting the application from recently executed application lists (Recent apps), or by selecting the application from a predetermined tray.

[0124] When the application execution event is generated in the home execution space 300, the display device 100 executes the corresponding application A1 in the application execution space 200 in operation S520. The display device 100 generates and displays a page 260 including an application execution window 262 in the application execution space 200 in operation S530.

[0125] FIGS. 6A and 6B illustrate a process of executing an application in a launcher screen according to an embodiment of the present disclosure.

[0126] Referring to FIG. 6A, when an icon 602 corresponding to the application which is desired to be executed by the user is touched on the launcher screen 310 generated and displayed using the home execution space 300, the corresponding application is executed in the application execution space 200 and thus the page 260 including the application execution window 262 may be generated.

[0127] Referring to FIG. 6B, when an icon corresponding to the application which is desired to be executed by the user is selected from the launcher screen 310 generated and displayed using the home execution space 300 and then dragged in a predetermined direction (for example, a top, bottom, left, or right direction), the corresponding application is executed in the application execution space 200 and thus the page 260 including the application execution window 262 may be generated. An embodiment of the present disclosure illustrates a case where, when the icon 604 is touched and then dragged in a top direction, the corresponding application is executed in a space corresponding to the top direction of the application execution space 200.

[0128] In a recent application list 312, recently executed applications are arranged in an execution order or pages generated according to the recently executed applications are sequentially arranged.

[0129] FIG. 7 illustrates an example of sequentially arranging recent pages according to an embodiment of the present disclosure.

[0130] Referring to FIG. 7, each page includes an application name and a thumbnail of one or a plurality of executed application execution windows. A recently executed application list includes a page 701 including a name 701-1 and a thumbnail 701-2 of a calculator application execution window, a page 702 including names 702-1 and 702-3 and thumbnails 702-2 and 702-4 of a video player application execution window, and a page 703 including a name 703-1 and a thumbnail 703-2 of an S note application execution window.

[0131] In the application execution window of each page, the application name, a border or underline displayed together with the application name, and the thumbnail may be displayed with different sizes, different colors, or different display schemes in order to distinguish whether the application execution window is in a resumed state or paused state. For example, a name of the application in the resumed state may be displayed with a first color, and a name of the application in the paused state may be displayed with a second color. The name or a border of the thumbnail of the application in the resumed state may be displayed with the first color, and the name or a border of the thumbnail of the application in the paused state may be displayed with the second color. For example, in FIG. 7, the application names 702-1 and 702-3 in the page 702 are displayed differently from the names 701-1 and 703-1 of the application windows in the paused state in the pages 701 and 703 in order to distinguish the page including the application window which is being executed from the pages in the paused state.

[0132] When the thumbnail of the application in the resumed state is selected through a touch input by the user, a page including a corresponding application execution window is generated and displayed by using the application execution space 200. When the thumbnail of the application in the paused state is selected through a touch input by the user, a new page is generated by using the application execution space 200 and a corresponding application execution window is included in the generated page. At this time, the paused state in the recent application list 312 is changed into the resumed state.

[0133] For example, referring to FIG. 7, when the thumbnail 702-2 of the gallery application execution window included in the page 702 is touched by the user, the page 260 including the corresponding gallery application execution window 262 is generated and displayed by using the application execution space 200. At this time, the video player application execution window 264 included also in the page 260 may be displayed together.

[0134] Meanwhile, pages included in the recent application list 312 may be displayed after a movement according to a scroll request of the user. The scroll request may be made by a left or right drag input, or an up or down drag input. An embodiment of the present disclosure describes a case where the recent application list 312 moves according to the left or right drag input.

[0135] Specifically, when the user touches and then drags a screen in a left direction in FIG. 7, the recent application list 312 is moved in the left direction, the page located in a left side disappears, and a next page 704 located in a right side appears as illustrated in FIG. 7. When the user touches and then drags a screen in a right direction in FIG. 7, the recent application list 312 is moved in the right direction, the page 703 located in a right side disappears, and a previous page 705 located in a left side appears.

[0136] Accordingly, the user can easily identify and control the pages of the application execution space 200 even in the home execution space 300 by using the recent application list 312.

[0137] FIGS. 8A to 8D illustrate a process of executing an application from a tray according to an embodiment of the present disclosure.

[0138] Referring to FIG. 8A, a display device 800 displays a first window 801 executing a first application A. The display device 800 may display a tray call button 810 at a left center of the first window 801. The tray call button 810 has a semicircle shape. When the tray call button 810 is touched, the tray opens in a right direction, which matches a users' intuition. However, it may be easily understood by those skilled in the art that the tray call button 810 may have any shape. The user can call the tray by touching the tray call button 810 or inputting a drag gesture 811 in a right direction. Since the tray call button 810 calls the application list, the tray call button 810 may be more generally named an application list call button.

[0139] FIG. 8B illustrates a called tray. In response to a tray call command such as the touch or drag of the tray call button, a controller (not shown) controls to display a tray 820 displaying a list of executable applications. The controller (not shown) controls to display thumbnail images 821, 822, 823, and 824 of the executable applications on the tray 820. The controller (not shown) may control to display all applications stored in a storage unit (not shown) on the tray 820. Alternatively, the controller (not shown) may identify attributes of the stored application and control to display an application which can operate in a multi window mode on the tray 820. The tray 820 also may be more generally named an application list.

[0140] After touching an application desired to be executed, for example, a fifth application E, the user may input a drag gesture 830 toward an area 835 in which the user desires to execute the application. Referring to FIG. 8C, when the user inputs the drag gesture 830 toward the area 835 in which the user desires to execute the application, the controller (not shown) changes a color or brightness of the area in which the application can be executed. Accordingly, the user may identify a shape of the window to be executed in the area 835 in which the user desires to execute the application before a final execution of the application, which may be named a ghost-view.

[0141] The user may stop the drag input 830 in the area 835 in which the user desires to execute the application. The gesture may be named a drag and drop. When the area 835 in which the user desires to execute the application is determined, the display device 800 reduces a first window 841 executing the first application A and displays the reduced first window 841 on the upper half of an entire screen, and displays a fifth window 842 executing the fifth application E on the lower half. As described above, displaying the two windows 841 and 842 not to overlap each other may be named a split mode, which will be described below in more detail.

[0142] FIGS. 9A and 9B illustrate a freestyle mode and a split mode according to an embodiment of the present disclosure.

[0143] Referring to FIG. 9A, a display device 900 includes a touch screen 910. The touch screen 910 displays a plurality of windows 911 and 912. A lower bar 920 is displayed on a lower end of the touch screen 910. As described above, a display mode in which the plurality of windows 911 and 912 overlap each other based on a display order of each window may be named the freestyle mode.

[0144] The window may be an area including an execution screen of a particular application and a title bar and a control area of an executed application. Objects related to the application may be displayed on the application execution screen. The objects may have various shapes, such as text, a symbol, an icon, a button, a checkbox, a picture, a video, a web, a map, and the like. When the user touches the object, a function or an event predetermined for the object may be executed in a corresponding application. The object may be called a view according to an operating system. The title bar may include at least one control key for controlling a display of the window. For example, the control key may be a window display minimizing button, a window display maximizing button, or a window end button.

[0145] Applications are programs independently implemented by a manufacturer of the display device 900 or an application developer. Accordingly, a pre-execution of one application is not required to execute another application. Further, although one application ends, another application can be continuously executed.

[0146] The applications are distinguished from a complex function application (or dual application) generated by adding some functions (memo function and message transmission/reception function) provided by another application to functions of one application in that the applications are independently implemented programs. However, the complex function application is a single application newly produced to have various functions and thus has differences from conventional applications. Accordingly, the complex function application provides only limited functions without providing various functions unlike the conventional applications. Further, users have the burden of separately purchasing such a new complex function application.

[0147] The controller 110 controls such that a plurality of windows 911 and 912 are displayed to partially overlap each other. The controller 110 may assign a display order to each of the windows 911 and 912. For example, the controller 110 may assign a first display order to the window 911 and a second display order to the window 912. Accordingly, the controller 110 displays the window 911 having a relatively higher display order to cover the window 912. A part of the window 912 having a relatively lower display order which overlaps the window 911 having the relatively higher order is not displayed.

[0148] The controller 110 may assign a highest display order to a window into which a control event has been most recently input. For example, when the user touches the window 911, the controller 110 assigns the highest display order to the window 911.

[0149] FIG. 9B illustrates an example of displaying two applications on a main display screen 910 in the split mode. When the user executes a plurality of applications, a controller (not shown) may simultaneously execute the plurality of applications and display the applications on the main screen 910.

[0150] In the split mode, a first window 940 and a second window 950 may be displayed on the main screen 910 so as not to overlap each other. For example, as illustrated in FIG. 9B, when the main screen 910 is divided into two parts, the first window 940 may be displayed on the left half of the main screen 910 and the second window 950 may be displayed on the right half of the main screen 910. Although the first window 940 and the second window 950 are arranged close to each other while sharing a common boundary 970, they do not overlap each other. The common boundary 970 is located between the first window 940 and the second window 950.

[0151] FIGS. 10A and 10B illustrate executing a plurality of applications through a touch input by the user according to an embodiment of the present disclosure.

[0152] FIG. 10A illustrates an embodiment of the present disclosure in which a plurality of applications are executed by a touch input of the user in the freestyle mode.

[0153] Referring to FIG. 10A, the display device 100 may display a plurality of application icons a1 to a9 and a tray 820 including a list of executable applications a10 to a13 on the launcher screen 310 by using the home execution space 300.

[0154] The display device 100 may execute the plurality of applications in the launcher screen 310 or the tray 820 according to a touch input of the user. As the user touches a plurality of applications, for example, first to third applications a3, a5, and a12, the display device 100 may execute each of the first to third applications a3, a5, and a12 in the application execution space 300. In the freestyle mode, the display device 100 may display all of a plurality of application execution windows, for example, all of first to third application execution windows 1011, 1012, and 1013 in a first page 1010.

[0155] FIG. 10B illustrates an embodiment of the present disclosure in which a plurality of applications are executed by a touch input of the user in the split mode.

[0156] Referring to FIG. 10B, in the split mode, the display device 100 may execute two application execution windows per page. When the applications a3, a5, and a12 are sequentially executed, the first and second application execution windows 1011 and 1012 may be executed together in a first page 1010-1 and the third application execution window 1013 may be executed in a second page 1010-2.

[0157] The case where the plurality of applications are executed by the user's touch input has been described in FIGS. 10A and 10B. According to another embodiment of the present disclosure, a plurality of applications may be executed according to a drag and drop input by the user.

[0158] FIGS. 11A and 11B illustrate executing a plurality of applications according to a drag and drop input by the user according to an embodiment of the present disclosure.

[0159] Referring to FIG. 11A, an embodiment in which a plurality of applications are executed by a drag and drop input of the user in the freestyle mode is illustrated. The display device 100 may display a plurality of application icons a1 to a9 and a tray 820 including a list of executable applications a10 to a13 on the launcher screen 310 by using the home execution space 300. As the user drags and drops a fourth application a13 from the tray 820 to the application execution space 200 while a plurality of applications, for example, the first to third applications a3, a5, and all are executed in a first page 1110 by using the application execution space 200, the display device 100 may execute the fourth application a13 in a second page 1120 of the application execution space 300 to generate and display a fourth application execution window 1121.

[0160] Referring to FIG. 11B, an embodiment in which a plurality of applications are executed by a drag and drop of the user in the split mode is illustrated. While the first and second applications a3 and a5 are executed in a first page 1130 by using the application execution space 200, the third application a13 of the tray 820 is dragged and dropped to the application execution space 200 by the user. Accordingly, the third application a13 is executed in a second page 1140 of the application execution space 300 instead of the first application a3, and a second application execution window 1142 and a third application execution window 1143 may be generated and displayed.

[0161] As described above, while the application is executed in the application execution space 200 and the page including the corresponding application execution window is generated, a mutual switching display between the page including the application execution window and the launcher screen 310 of the home execution space 300 becomes possible.

[0162] FIGS. 12A to 12C illustrate mutual switching between a launcher screen of a home execution space and a page of an application execution space according to an embodiment of the present disclosure.

[0163] Referring to FIGS. 12A to 12C, the display device 100 executes a launcher L having first to third views L1, L2, and L3 by using the home execution space 300 and executes first to fourth applications A1, A2, A3, and A4 by using the application execution space 200. The first application A is executed in a first page P1, the second and third applications are executed in a second page P2, and the fourth application A4 is executed in a third page.

[0164] The display device 100 displays the first view L1 of the launcher L of the home execution space 300 on the touch screen 190 as illustrated in FIG. 12A, and then may switch the displayed first view L1 to the first page P1 of the application execution space 200 and display the switched first page P1 on the touch screen 190 according to generation of a display change event as illustrated in FIG. 12B. The display device 100 displays the first page P1 of the application execution space 200 on the touch screen 190 as illustrated in FIG. 12B, and then may switch the displayed first page P1 to the first view L1 of the launcher L of the home execution space 300 and display the switched first view L1 on the touch screen 190 according to generation of a display change event as illustrated in FIG. 12C. The display change event may be generated according to a gesture input by the user.

[0165] FIGS. 13A and 13B illustrate cases where a display change event is generated by a gesture input according to an embodiment of the present disclosure.

[0166] FIG. 13A illustrate a case where a display change event is generated by a flick of the user according to an embodiment of the present disclosure. Referring to FIG. 13A, as a gesture of flicking the first view L1 of the home screen in a bottom direction is input, the first page P1 of the application execution space may be displayed. This enables the user to recognize a concept that the application execution space exists in a higher level of the home screen, which matches a user's intuition. A widget displayed on an upper part of the first view L1 may be also displayed on a lower part of the first page P1 of the application execution space in (b) of FIG. 13A, but the widget may not be displayed in (c) of FIG. 13A. An animation effect may be created in which the first view L1 is switched to the first page P1.

[0167] FIG. 13B illustrate a case where a multi touch, for example, a 3-touch gesture input is used. Referring to (a) of FIG. 13B, as a gesture of multi-touching and then dragging the first view L1 of the home screen in a bottom direction is input, only the first page P1 of the application execution space may be displayed as illustrated in (b) and (c) of FIG. 13B. The same performance as that in (a) of FIG. 13A is executed in (b) and (c) of FIG. 13B, thereby creating the animation effect. In response to a gesture of multi-touching and then dragging the first page P1 of the application execution space in a top direction is input, the first view L1 of the home screen may be displayed as illustrated in (d) and (e) FIG. 13B.

[0168] Further, switching from the launcher screen 310 of the home execution space 300 to the page of the application execution space 200 may be made according to a page selection on a minimap.

[0169] FIGS. 14A and 14B illustrate cases where a display change event is generated according to a page selection on a minimap according to an embodiment of the present disclosure.

[0170] Referring to FIG. 14A, when a background area of the first view L1 is pressed by the user for a predetermined time or longer (i.e., a long press is input) while the first view L1 of the launcher L of the home execution space 300 is displayed on the touch screen 190, a minimap M for currently executed applications may be displayed on the first view L1 of the launcher L. For example, thumbnails 1401 to 1404 indicating pages corresponding to the currently executed applications, respectively may be displayed on the minimap M. The user may select the thumbnail 1404 which the user desires to switch from the thumbnails 1401 to 1404 displayed on the minimap M. When the thumbnail 1404 is selected by the user, the display device 100 switches the first view L1 displayed on the touch screen 190 to the first page P1 of the application execution space 200 corresponding to the selected thumbnail and displays the switched first page P1.

[0171] Referring to FIG. 14B, when a predetermined key such as a home key h is pressed by the user while the first view L1 of the launcher L of the home execution space 300 is displayed on the touch screen 190, a minimap M for currently executed applications may be displayed on the first view L1 of the launcher L. The user may select the thumbnail 1404 which the user desires to switch from the thumbnails 1401 to 1404 displayed on the minimap M. When the thumbnail 1404 is selected by the user, the display device 100 switches the first view L1 displayed on the touch screen 190 to the first page P1 of the application execution space 200 corresponding to the selected thumbnail and displays the switched first page P1.

[0172] FIG. 15 illustrates an execution of a minimap by a user's gesture according to an embodiment of the present disclosure.

[0173] Referring to FIG. 15, the controller 110 may distinguishably define a home screen space 1402 and an application execution space 1401. A launcher screen 1420 of at least one executable application may be displayed on the home screen space 1402. A minimap 1410 for currently executed applications may be displayed on a lower end of the launcher screen 1420. For example, the display device controls to display a thumbnail of a currently executed first application 1411, a thumbnail of a second application 1412, and a thumbnail of a third application 1413 on the minimap 1410 of the home screen space 1402. Meanwhile, it may be identified even in the application execution space 1434 that the first application 1411, the second application 1412, and the third application 1413 are being executed. Further, it may be identified in the minimap defined in the application execution space that the first, second, and third applications are executed.

[0174] The user 10 desires to additionally execute a fourth application 1421, and accordingly, inputs a drag gesture from an icon of the fourth application 1421 to the minimap 1410. In order to execute the fourth application 1421 between the second application 1412 and the third application 1413, the user 10 may input a drag gesture 1422 such that the icon of the fourth application 1421 overlaps the thumbnail of the third application 1413.

[0175] The controller (not shown) may execute the fourth application 1421 in the same application execution space or an adjacent application execution space of the third application 1413 based on an execution input of the fourth application 1421. The controller (not shown) controls to display a window executing the fourth application 1421 based on a set mode.

[0176] For example, when the set mode is the freestyle mode, the controller (not shown) controls to display a window 1442 executing the fourth application 1421 to overlap a window 1441 executing the third application 1413. In this case, the controller (not shown) controls to display the window 1442 executing the fourth application 1421 in the same application workspace 1440 as that of the window 1441 executing the third application 1413.

[0177] When the set mode is the split mode, the controller 110 controls to display a window 1452 executing the fourth application 1421 and a window 1451 executing the third application 1413 in the split mode. In this case, the controller (not shown) controls to display the window 1452 executing the fourth application 1421 in the same application workspace 1450 as that of the window 1451 executing the third application 1413.

[0178] When the set mode is a full screen mode, the controller 110 controls to display a window 1461 executing the fourth application 1421 close to a window 1462 executing the third application 1413. In this case, the controller 110 controls to display the window 1461 executing the fourth application 1421 and the window 1462 executing the third application 1413 in different application workspaces.

[0179] As described above, the controller (not shown) may control to generate and display windows executing applications in various ways according to the set mode.

[0180] FIGS. 16A to 16C illustrate a concept describing a method of displaying switching between views in a home execution space according to an embodiment of the present disclosure.

[0181] Referring to FIGS. 16A to 16C, the display device 100 executes the launcher L having the first to third view L1, L2, and L3 by using the home execution space 300.

The display device 3000 may display a third window 3040 executing the third application A3 on the second point of the application execution space 3020 based on the input execution command, (i.e., the drag gesture 3035). A size and a shape of the third window 3040 may have default value or a value set by the user before ending. Since the window into which the user 10 more recently inputs the gesture is the third window 3040, the controller (not shown) may assign a higher task order to the third application A3 rather than the first application A1. Accordingly, the controller 110 may control such that the third application A3 is displayed to cover the first application A1.

[0237] FIGS. 31A to 31H illustrate a method of executing applications according to another embodiment of the present disclosure. Particularly, various embodiments of FIGS. 31A to 31H illustrate a method of executing applications in another application execution space page set in the split mode.

[0238] Referring to FIG. 31A, a display device 3100 displays an application execution space. The display device 3100 displays a tray 3110 including icons 3111 to 3117 of executable applications on a left side of the application execution space. FIG. 31B illustrates the application execution space corresponding to FIG. 31A. The application execution space includes a first page 3101, a second page 3102, and a third page 3103. In this case, the display device 3100 displays the first page 3101.

[0239] The user 10 may control the display device 3100 to execute a seventh application A7. The user 10 may control to execute the seventh application A7 in the second page 3102 of the application execution space. Accordingly, the user 10 may input an application execution space switching gesture. The user 10 may touch an icon 3117 of the seventh application A7 and input the drag gesture 3115 to a right boundary of the application execution space, that is, the touch screen. The controller 110 recognizes the drag gesture 3025 to the right boundary as the application execution space switching gesture, a page switching gesture, or a sub space switching gesture. Accordingly, the controller 110 switches the physically displayed application execution space from the first page 3101 to the second page 3102. Also in the application execution space of FIG. 31D, the drag gesture to the boundary between the first page 3101 and the second page 3102 may be recognized as the application execution space switching gesture from the first page 3101 to the second page 3102.

[0240] Referring to FIG. 31E, the user may drag the icon of the seventh application A7 to an upper part 3140 of the second page 3102 and then drop the icon of the seventh application A7 as illustrated in FIG. 31G. When the user 10 inputs a drag and drop gesture to an area in which the user desires to execute the application, the controller 110 changes a color or brightness of the area 3140 where the application can be executed in accordance with the drag and drop gesture 3125 into a color or brightness different from an application execution space 3130 of the second page. When the input of the drag and drop gesture ends, the controller 110 controls to display the seventh window 3140 on an upper part of the application execution space 3130 of the second page. Meanwhile, in the application execution space of FIG. 31F, the application execution space physically displayed by the display device 3100 may change from the first page 3101 to the second page 3102. Further, in the application execution space of FIG. 31H, it may be identified that the seventh window 3104 is arranged in an upper part of the second page 3102.

[0241] As described above, it is possible to create an effect in which the user can easily execute the application in a desired part of another page which is not the displayed application execution space page.

[0242] FIGS. 32A to 32D illustrate a method of executing applications according to an embodiment of the present disclosure. Particularly, various embodiments of FIGS. 32A to 32D illustrate concepts describing a configuration of executing applications in a desired position by using a minimap.

[0243] Referring to FIG. 32A, a display device 3200 displays an application execution space 3220. The display device 3200 displays a tray 3210 including icons 3211 to 3217 of executable applications on a left side of the application execution space 3220. The display device 3200 also displays a minimap 3230 of the application execution space on an upper part of the application execution space 3220. A first page 3231, a second page 3232, a third page 3233, and a fourth page 3234 may be displayed on the minimap 3230.

[0244] Referring to FIG. 32B, the user 10 may input a drag gesture 3235 from the icon 3217 of the seventh application A7 to an upper part of the second page 3232 in the minimap 3230. The user 10 may drag the application icon to a desired page of the application execution space in which the user desires to execute the application or a desired part of the desired page. The controller 110 may recognize the drag gesture 3235 of the application icon to the minimap as an application execution command. When the application execution command is input, the controller 110 detects an execution page and an execution position in the application execution space. The controller 110 detects an execution page and an execution position of the application execution space based on a set display mode. For example, in FIG. 32B, the display mode may be set as the vertical split mode. Accordingly, when the user 10 drags the icon of the seventh application A7 to the second page 3232 of the minimap 3230 as indicated by the reference numeral 3235, the controller 110 may control to display a ghost-view in the upper part of the second page 3232.

[0245] Alternatively, the controller (not shown) may enlarge the second page 3232 of the minimap 3230 into which the drag gesture 3235 has been input and display the enlarged second page 3232 as illustrated in FIG. 32C. Accordingly, the user 10 may determine whether the drag gesture 3235 which the user has input is accurately input. When the input of the drag gesture 3235 ends, the controller (not shown) displays a second page 3250 of the application execution space and displays a seventh window 3260 executing the seventh application A7 on an upper part of the second page 3250 as illustrated in FIG. 32D. As described above, the display mode set as the vertical split mode is merely an example, and it may be easily understood by those skilled in the art that the display device 3200 according to the present disclosure can execute the applications by using the minimap in various modes such as the horizontal split mode, the quarter split mode, the freestyle mode, the full screen mode and the like.

[0246] As described above, the user 10 may easily determine the execution page and the execution position in the application execution space by using the minimap 3230.

The user 10 may control the display device 3300 to execute a seventh application A7. For example, the user 10 may touch the icon 3317 of the seventh application A7 and input a drag gesture 3325 to the application execution space 3320.

[0249] FIG. 33B illustrates a concept of the application execution space, which includes a first page 3301, a second page 3302, and a third page 3303. The page physically displayed by the display device 3300 is the first page 3301. Meanwhile, in FIG. 33A, the user 10 may not end a drag and drop gesture by maintaining a touch for the icon 3317 of the seventh application A7. Accordingly, the controller (not shown) may determine that the application execution command does not end.

[0250] The user 10 may input a flick gesture 20 for the first page 3320 of the application execution space in a left direction while maintaining the touch for the icon 3317 of the seventh application A7. For example, as illustrated in FIG. 33C, the user 10 may maintain the touch for the icon 3318 of the seventh application A7 by using one hand and input the flick gesture 20 by using the other hand. As illustrated in FIG. 33D, the display device 3300 may display a first page 3301 until the time when the flick gesture 20 is input. The controller 110 may recognize a flick gesture in a predetermined direction as a page switching gesture while mainlining the touch for the icon as described above.

[0251] Referring to FIGS. 33E and 33F, the controller 110 switches the page of the physically displayed application execution space from a first page 3320 to a second page 3340. The display mode may be set as the vertical split mode in FIG. 33E, and accordingly, the controller 110 recognizes that the icon 3318 of the seventh application A7 exists in a lower part 3304 of the second page of the application execution space as illustrated in FIG. 33F.

[0252] Referring to FIG. 33G, the user may drop the icon 3318 of the seventh application A7, and the controller 110 recognizes that the application execution command is input. The controller 110 controls to display the seventh window 3350 executing the seventh application A7 on the second page 3340 of the application execution space based on the input application execution command. FIG. 33H illustrates the application execution space in which a seventh window 3305 is arranged in a lower part of the second page 3302.

[0253] As described above, the user may maintain a touch for an icon of a particular application by using one hand and input a flick gesture in a predetermined direction by using the other hand. Accordingly, the display device may maintain the touched application icon and switch the page of the application execution space. The user may easily control the display device such that the page is moved to a desired page, and easily execute an application in a desired position, thereby maximizing the user's convenience.
