A contact state with the touch screen may include a state where the finger, the thumb, or the stylus pen directly contacts the touch screen or closely approaches the touch screen without a direct contact.

[0168] The portable device 100 is a device for executing an application, a widget, and a function which is stored in the storage unit and can be executed by the controller 110 through the touch screen. In general, the touch screen provides application, widgets, functions, and graphic objects (that is, soft key or short-cut icon) corresponding to a group thereof, and the portable device executes a corresponding application, widget, or function in response to the detection of the touch gesture of the user on each graphic object.

[0169] Here, the widget refers to a mini application which is downloaded and used by the user or can be generated by the user, and includes, for example, a weather widget, a stock widget, a calculator widget, an alarm clock widget, a dictionary widget and the like. A short-cut icon for executing the widget may provide simple advance information through a corresponding widget application. For example, an icon of the weather widget simply provides a current temperature and a weather symbol and a widget application executed through a touch of the icon provides much more information such as weather in each period / area. The application in this specification includes a widget based application and a non-widget based application.

[0170] In one embodiment, the touch screen is implemented by one panel (or tablet) and displays one or a plurality of task screens corresponding to one or a plurality of applications under a control of the controller. In another embodiment, the touch screen display is implemented by two panels which are physically separated and mutually connected with each other by a predetermined connector, and the panels may be folded in or folded out by a predetermined angle with respect to the connector. Here, the connector may be a hinge, a flexible connector, or a part of a flexible touch screen. In another embodiment, the touch screen display may be implemented by a flexible touch screen which can be folded or bent at least one or more times. The touch screen display displays one or a plurality of task screens related to one or a plurality of applications under a control of the controller.

[0171] FIG. 2 is a perspective view of the portable device according to an embodiment of the present invention. FIG. 2 shows a configuration in a case where the portable device includes a display device including two touch screens which are connected by a hinge.

[0172] Referring to FIG. 2, the portable device 100 includes a first panel 2 and a second panel 4, and the first panel 2 and the second panel 4 are connected by a hinge 6 to be relatively movable. One surface of the first panel 2 has a first touch screen 12, and at least one physical button 5 may be disposed in a lower end of the first touch screen 12. One surface of the second panel 4 has a second touch screen 14 disposed in parallel with the first touch screen 12, and at least one physical button 5' may be disposed in a lower end of the second touch screen 14. The physical buttons 5 and 5' include at least one of a push button and a touch button. As one embodiment, the first touch screen 12 arranged on the first panel 2 having a speaker 20 and a microphone 22 operates as a main screen, and the second touch screen 14 arranged on the second panel 4 operates as a sub screen. As one embodiment, the first panel 2 includes a front camera 24, and the second panel 4 includes a rear camera 26. As another example, as the front camera 24 is disposed in the same surface as that of the second screen 14, in a state where the first panel 2 and the second panel 4 are unfolded, the front camera 24 may work as a front camera, and in a state where the first panel 2 and the second panel 4 are folded, the front camera 24 may work as a rear camera.

[0173] As long as the first panel 2 and the second panel 4 are connected by the hinge 6 to be relatively movable, the portable device 100 can be any device such as a mobile phone, a notebook, a tablet PC, a PMP or the like. Although a case where the first touch screen 12 and the second touch screen 14 are included in the first panel 2 and the second panel 4, respectively has been described, the case can be applied to a device in which the touch screen display is provided to only one of the two panels. Further, at least one of the function buttons 5 and 5' in lower ends of the touch screens may be omitted. Furthermore, although a case where the first panel 2 and the second panel 4 are connected by the hinge 6 has been described as an example, the hinge 6 may be replaced with another component as long as the first panel 2 and the second panel 4 can be folded through a relative movement.

[0174] The portable device includes a display device having a first touch screen and a second touch screen which are physically or graphically separated, and supports various screen modes as shown in FIG. 3 by using the two touch screens.

[0175] FIG. 3 (including FIGs. 3A to 3D) is a diagram illustrating screen modes according to a relative angle between the first panel 2 and the second panel 4 of the portable device 100. The relative angle is a rotation angle at which the second panel 4 rotates with respect to the first panel 2 in a predetermined direction (for example, counterclockwise).

[0176] FIG. 3A is a perspective view of the folded portable device 100, which shows a state where the first panel 2 and the second panel 4 contact each other while each of the touch screens 12 and 14 of the first panel 2 and the second panel 4 faces outward, that is, a state where the portable device 100 is completely folded outward. The state corresponds to a dual screen. At this time, the relative angle is 0 degrees. For example, when the relative angle between the first and second panels 2 and 4 ranges from 0 to 60 degrees, the portable device recognizes a dual screen mode. The dual screen mode is useful when the portable device is in a locked state in which the portable device is not used and useful in a call application. The touch screen 12 in a front surface may display a task screen of at least one application and the touch screen 14 in a rear surface may be turned off in the dual screen mode. Some applications can turn on the touch screen 14 in the rear surface by using an option menu.

[0177] FIG. 3B shows a state where the first panel 2 and the second panel 4 are parallel in which the relative angle is 180 degrees or close to 180 degrees within a predetermined range, that is, an unfolded state. The state corresponds to a double screen. 7For example, when the relative angle between the first and second panels 2 and 4 ranges from 175 to 185 degrees, the portable device may consider that the first and second panels 2 and 4 are unfolded. The double screen mode may provide various view modes of displaying two task screens for two applications in the two touch screens 12 and 14, respectively, displaying two task screens for one application in the two touch screens 12 and 14, or widely displaying one task screen for one application in the two touch screens 12 and 14. When there is no application executed within one touch screen, the corresponding touch screen may display a home screen.

[0178] FIG. 3C shows a state where the relative angle of the second panel 4 with respect to the first panel 2 exceeds 180 degrees, that is, a state where the two touch screens 12 and 14 are slightly folded inward. That state corresponds to an in-folded screen. For example, when the relative angle between the first and second panels 2 and 4 ranges from 180 to 210 degrees, the portable device recognizes an in-folded screen mode. The in-folded screen mode corresponds to the state where the two touch screens 12 and 14 are slightly folded inward and is useful when the portable device is used as a similar form to that of a notebook or an electric book. The in-folded screen mode may be used similarly to the double screen mode.

[0179] FIG. 3D shows a state where the relative angle of the second panel 4 with respect to the first panel 2 is smaller than 180 degrees, that is, a state where the two touch screens 12 and 14 are nearly completely folded outward in opposite directions. The state corresponds to an out-folded screen. For example, when the relative angle between the first and second panels 2 and 4 ranges from 30 to 90 degrees, the portable device recognizes an out-folded screen mode. The out-folded screen mode has a structure in which the two touch screens 12 and 14 are folded outward and is useful when the portable device is charged because the portable device can stand on the floor in a triangle shape, when the portable device is used as a digital clock or frame, and when personal broadcasting, a movie, a video or the like is watched for a long time. As another embodiment, the out-folded screen mode may be applied to an application requiring cooperation or interaction between two or more users, for example, a video conference, a collaborative game or the like. Some applications may display a task screen in only the touch screen 12 of the front surface in the dual screen mode and turn off the touch screen 14 of the rear surface. Some applications may turn on the touch screen 14 of the rear surface by using an option menu.

[0180] FIG. 4 is a perspective view of the portable device according to another embodiment of the present invention. As illustrated in FIG. 4, the portable device 100 includes a display having two flexible touch screens 12 and 14. The two touch screens 12 and 14 may be mutually connected by a flexible connector 18 and freely folded or bent by a flexible connector 20.

The first page 202 and the second page 204 can display the widget areas 212 and 218 and / or the shortcut icon 214 in a common background image or respective background images designated as a background screen. As a selectable embodiment, one background image may be displayed over the first and second touch screens 12 and 14.

[0187] Each shortcut icon corresponds to each application or each application group, and the corresponding application is executed or shortcut icons included in the corresponding application group are displayed through a detection of a user's touch. Each widget area or each shortcut icon may be basically provided when the portable device is manufactured or may be formed by the user.

[0188] In addition, the first touch screen 12 can further display a counter 202a indicating a page of the home screen, frequently used applications, for example, a call application, a contact information application, a message application, a dock area 216 including short icons of an application menu providing application lists, and a status bar 206 providing signal intensity indicator(s) for wireless communication such as cellular or WiFi communication, a Bluetooth connection mode, a received message, a battery status indicator, and a current time together with the first page 202. The second touch screen 14 can further display a page counter 204a and a status bar 208. The status bar on the second touch screen 14 can provide information different from that of the first touch screen 12. The status bars 206 and 208 may be displayed together with the home screen or the application or may be omitted. The status bars 206 and 208 are maintained within the first and second touch screens 12 and 14 regardless of switching of pages. In the following description, description of whether the status bars 206 and 208 are displayed will be omitted.

[0189] The home screen may further provide additional pages including one or more widget areas and / or one or more icons within a predetermined maximum number of pages, and the pages are switched by a pre-designated touch gesture.

[0190] The portable device detects a pre-designated touch gesture 200a to switch a page of the home screen in at least one of the first touch screen 12 and the second touch screen 14 and proceeds to FIG. 6B.

[0229] When the items are scrolled, each of the items is not displayed over the two touch screens. That is, when each of the items reaches the hinge (or connector), it skips over the hinge and then is displayed in the next touch screen.

[0230] The touch screens of the portable device are switched to a portrait view mode or a landscape view mode based on a detection signal received from one or more accelerometers and then display information according to the switched mode. That is, the accelerometer may be included in the sensor module 170 and senses a rotation of the portable device. The accelerometer detects the switching between the portrait view mode in which the touch screens of the portable device are arranged in a left side and a right side and the landscape view mode in which the touch screens of the portable device are arranged in an upper side and a lower side, and generates the detection signal.

[0231] When the portable device is rotated substantially by 90 degrees and switched to the landscape view mode while displaying items in a grid form in the portrait view mode, the items within the grid may be rotated in a horizontal direction and scrolled. When the items are horizontally arranged, the items on the grid may be scrolled in a vertical direction according to a selection of the manufacturer or user or simultaneously scrolled in both an upper screen and a lower screen in a horizontal direction. Similarly, a movement of each grid is based on a direction and a speed of the motion of the touch gesture.

[0232] As another selectable embodiment, when a list is displayed in one touch screen and not displayed in the other touch screen in the portrait view mode, the list is displayed in both the two touch screens according to a setting of the manufacturer or user or information of another touch screen is extensively displayed in the two touch screens when the portable device rotates by 90 degrees.

[0233] When the portable device is rotated by 90 degrees and switched to the landscape view mode while displaying the home screen or the application menu in the portrait view mode, the portable device may operate to display a search window or a pre-designated application (for example, a search window of an Internet browsing application) in at least one of the touch screens.

[0234] FIG. 8C illustrates an example of a user interface for using the landscape view mode of the home screen according to an embodiment of the present invention. Here, although a touch screen layout in a case where the portable device rotates by 90 degrees in a left direction is illustrated, the case can be applied when the portable device rotates by 90 degrees in a right direction. In the landscape view mode, it is described that the touch screen located in an upper part is the first touch screen 12.

[0235] Referring to FIG. 8C, when portable device is switched to the landscape view mode, that is, the portable device rotates by about 90 degrees while providing the home screen or pages of the application menu through the first and second touch screens 12 and 14 in the portrait view mode as illustrated in FIG. 6A or FIG. 8A, the first touch screen 12 displays a search window 282 interworking with the Internet browsing application or a pre-designated application. As one embodiment, the search window 282 may be displayed with or on the previously displayed home screen or page of the application menu of which a mode is switched to the landscape view mode. As another embodiment, the search window 282 may be displayed in an upper part of the second touch screen 14. As a selectable embodiment, the dock area 216 may be displayed in a position of one of the first and second touch screens 12 and 14, for example, a right end of the first touch screen 12 in the landscape view mode and shortcut icons within the dock area may be vertically arranged.

[0236] As a selectable embodiment, when the switching to the landscape view mode is performed, the second touch screen 14 replaces the page of the home screen with at least one pre-designated application, that is, a task manager screen including at least one running application 286 and displays the replaced page in the shown example. At this time, preview windows including simple information on each running application 286 or last executed information may be displayed in the task manager screen of the second touch screen 14 in an in activated state, for example, in a shaded state, or a shortcut icon of each running application 286 may be displayed in a grid or a list form. Further, the preview windows of the running application 286 may be displayed to partially overlap each other or displayed in a grid form not to overlap each other. The preview window refers to an area in a deactivated state in which a touch input is not allowed in comparison with a task screen which actually executes an application and provides a user interface such as the touch input.

[0237] As another embodiment, when the switching to the landscape view mode is performed, the second touch screen 14 displays the previously displayed home screen or page of the application menu of which a mode is switched to the landscape view mode and the search window 282 or displays a pre-designated application and the search window 282. The pre-designated application may be designated by the manufacturer or user. For example, the pre-designated application may be a quick search application, an Internet browsing application, a recommended application list in the landscape view mode provided by the portable device, and another application designated by the user.

[0238] As a selectable embodiment, when a touch gesture of the user is detected from one of the preview windows (or shortcut icons) of the running application, the second touch screen 14 can display a task screen (providing an activated user interface) through an execution of the corresponding application.

[0239] When a touch gesture (for example, tap gesture) of the user is detected from an input area 282a included in the search window 282 displayed in the first touch screen 12 in the landscape view mode in which the first touch screen is located in the upper part and the second touch screen 14 is located in the lower part, a virtual keypad for receiving a text input, that is, a keypad area (not shown) is displayed in a predetermined area, for example, a lower part of the first touch screen 12, a lower part of the second touch screen 14, or the whole second touch screen 14. When a keyword desired to be searched for through the keypad area is input by the user and then a touch gesture (for example, tap gesture) of the user is detected from a search execution key 282b displayed within the search window 282 or next to the search window 282, search results corresponding to the keyword provided by the search application interworking with the search window 282 are displayed in the first touch screen 12, the second touch screen 14, or entire areas including the first and second touch screens 12 and 14.

[0240] The portable device includes the display device including the first touch screen and the second touch screen arranged on at least one foldable panel and supports the following various view modes by using the two touch screens.

[0241] A multi mode or a multi tasking mode refers to a mode in which different applications are displayed in two touch screens, respectively, and each of the applications may respond to a touch gesture detected from the corresponding touch screen. For example, the first touch screen displays a photo gallery application, and the second touch screen displays an Internet browsing application. The portable device can swap information of the two touch screens by a pre-designated touch gesture. For example, the touch gesture includes two touches which are generated in the two touch screens, respectively and move to the hinge (or connector). The portable device can replace the photo gallery application of the first touch screen with the Internet browsing application and replace the Internet browsing application of the second touch screen with the photo gallery application in response to the detection of the two touches.

[0242] A main-sub mode (or slit mode) displays two task screens for one application in two touch screens, respectively. The two task screens provide task screens having different depths (or levels) of the application or task screens having different functions. That is, some applications may be configured to provide a plurality of task screens and the task screens may have different depths.

[0243] For example, the photo gallery application can provide a search screen including a plurality of thumbnail images and a full image screen displaying a picture image of one thumbnail image selected from the thumbnail images with a larger size, that is, with a full size through different touch screens. In this case, the full image screen may be designated to have a final depth. As another example, a music play application provides a playlist screen including a plurality of listed music and a music play screen for playing one of the music through different touch screens. In this case, the music play screen may be designated to have a final depth.

[0244] A full mode (or expanded mode) extensively displays one task screen of one application in two touch screens regardless of the hinge (or connector). For example, the first touch screen displays a first page of thumbnail images provided through the photo gallery application and the second touch screen displays a second page of the thumbnail images. As another example, one picture image is displayed to fully fills the whole of the first touch screen and the second touch screen. Here, displaying the picture image to fully fill the touch screens means that the picture image is displayed to fully fill horizontal widths and / or vertical widths of the first and second touch screens. As still another example, the first touch screen displays a map area having a first scale of a map application and the second touch screen displays a map area having a more detailed scale.

[0245] A change between the view modes may be achieved according to a running application, a detection of the touch gesture on the first and / or second touch screens, or a motion gesture of the portable device. The motion gesture includes a physical motion such as a rotation of the portable device and bending / folding of the first and / or second touch screens. Here, the bending / folding of the touch screens may refer to bending / folding within a predetermined relative angle. As a selectable embodiment, the change between the view modes is loaded by expanding a setting menu of the portable device or an upper status bar of the main touch screen or two touch screens and may be achieved by using a view mode changing button disposed within a quick panel allowing a quick control of a change in a status and a mode of the portable device.

[0246] FIG. 9 (including FIGs. 9A to 9J) illustrates an example of a change in the view mode according to a touch gesture according to an embodiment of the present invention.

[0247] As illustrated in FIG. 9A, the first touch screen 12 displays a first application 302 and the second touch screen 14 displays a second application 304. For example, the first touch screen 12 displays the photo gallery application and the second touch screen 14 displays the Internet browsing application.

[0248] As illustrated in FIG. 9B, when the portable device 100 detects a predetermined touch gesture 306 from the first and / or second touch screens 12 and / or 14, the first application 302 of the first touch screen 12 is displayed in both the first touch screen 12 and the second touch screen 14. At this time, as an example, the first application 302 may be displayed in the two touch screens 12 and 14 in the full mode or separately displayed in the two touch screens 12 and 14 through two task screens in the main-sub mode.

[0249] For example, the touch gesture 306 includes actually simultaneously generated two or more flicks which move in a direction from the first touch screen 12 to the second touch screen 14. As another example, the touch gesture 306 includes actually simultaneously generated two or more touch drags which move in a direction from the first touch screen 12 to the second touch screen 14. Specifically, when the portable device 100 detects a plurality of touches starting at the first touch screen 12 and detects that the detected touches simultaneously move in a direction from the first touch screen 12 to the second touch screen 14, the portable device 100 displays the first application 302 in the both the first touch screen 12 and the second touch screen 14. As one embodiment, the flicks or the touch drags may move through the hinge or connector between the first and second touch screens 12 and 14.

[0250] Here, although it has been illustrated that the flicks or the touch drags are generated in parallel, the flicks or the touch drags can be generated irregularly. As a selectable embodiment, when an interval between the flicks or the touch drags is equal to or smaller than a predetermined value, that is, 2 cm, the portable device can recognize the touch gesture for changing the view mode. As another selectable embodiment, positions of the first touch screen 12 where the touches are first detected may be horizontally or vertically arranged side by side.

[0251] As still another embodiment, the touch gesture 306 includes a pinch gesture for expanding a selected area, that is, a pinch zoom-in gesture. As an embodiment, two touches of the pinch zoom-in gesture start at the first touch screen 12, wherein a first touch is released within the first touch screen 12 and a second touch is released within the second touch screen 14.

[0252] At this time, the task screen of the first application 302 may be displayed while sliding in a direction from the first touch screen 12 to the second touch screen 14 according to a motion (and a speed) of the touch gesture 306. When the first and second touch screens 12 and 14 are connected by the hinge or separated connector not to be continuous, the task screen of the first application 302 may be displayed over both the first and second touch screens 12 and 14 when sliding through the hinge or connector.

[0253] Although not illustrated, the first application 302 enlarged over the first and second touch screens 12 and 14 by the touch gesture 306 may be reduced within the first touch screen 12 by another pre-designated touch gesture. As one example, when a pinch zoom-out gesture including two touches which start at first and second touch screens 12 and 14, respectively and are released in one touch screen, for example, the second touch screen 14 is detected, the portable device reduces the first application 302 and displays the reduced first application 302 in the second touch screen 14. At this time, the first touch screen 12 can display the second application 304 or the home screen.[2-2. From the full mode to the main-sub mode]

[0254] When the first application 302 is the photo gallery application, the photo gallery application 302 displays the first page of a plurality of thumbnail images in the first touch screen 12 as illustrated in FIG. 9A. In response to the detection of the touch gesture 306 of FIG. 9B, the portable device displays the first and second pages 302a and 302b of the plurality of thumbnail images in the first and second touch screens 12 and 14 as illustrated in FIG. 9C. At this time, according to a motion of the touch gesture 306, the first page 302b of the thumbnail images displayed in the first touch screen 12 slides to the second touch screen 14 and the second page 302a of the thumbnail images slides to the first touch screen 12 following the first page 302b.

[0255] When a plurality of items such as the thumbnail image are displayed in the first and second touch screens 12 and 14 in a grid form, the items may be scrolled (that is, translated) according to a motion and a speed of the touch gesture as illustrated and described in FIGs. 8A and 8B. That is, when a touch gesture such as the flick or sweep is generated in one of the first and second touch screens 12 and 14, the thumbnail images are scrolled according to a motion direction and a speed of the touch gesture. At this time, the thumbnail images may be scrolled over the hinge (or connector) between the first and second touch screens 12 and 14.

[0256] Referring to FIG. 9D, the portable device 100 detects a touch gesture 310 (for example, tap gesture) of the user on a first thumbnail image 306 which is one of the thumbnail images 302a of the first touch screen 12, that is, "thumbnail21". Then, as illustrated in FIG. 9E, the second touch screen 14 replaces the first page 302b of the thumbnail images with a picture image 306a of the first thumbnail image 306 and displays the replaced picture image 306a in response to the detection of the touch gesture 310. The picture image 306a has a larger size than the first thumbnail image 306 and may be displayed to fill one of a horizontal width and a vertical width of the second touch screen 14. As illustrated in FIG. 9F, when a touch gesture 312 (for example, tap gesture) of the user is detected on a second thumbnail image 308 among the thumbnail images 302a of the first touch screen 12, the picture image 306a of the first thumbnail image 306 is replaced with a picture image 308a of the second thumbnail image 308 and the replaced picture image 308a is displayed in the second touch screen 14 in response to the detection of the touch gesture 312.

[0257] Referring to FIG. 9G, the portable device 100 detects a predetermined touch gesture 320 on the first picture image 308a displayed in the second touch screen 14 in a state where the first touch screen 12 displays the plurality of thumbnail images 302a provided through the photo gallery application and the second touch screen 14 displays the first picture image 308a of the first thumbnail image selected from the plurality of thumbnail images 302a. Then, as illustrated in FIG. 9H, the portable device 100 enlarges the first picture image 308a and displays the enlarged first picture image 308a to fully fill the first touch screen 12 and the second touch screen 14. The first picture image 308b expands up to the first touch screen 12 while covering the thumbnail images 302a of the first touch screen 12. When the expansion is completed, a part (for example, a left half) of the first picture image 308a is displayed in the first touch screen 12 and the remaining part (for example, a right half) of the first picture image 308b is displayed in the second touch screen 14. As a selectable embodiment, when the first picture image 308b is an image generated in the portrait view mode (vertically long image), the first picture image 308b may be displayed in one of the first and second touch screens 12 and 14.

[0258] As one embodiment, the touch gesture 320 includes a pinch gesture of expanding a selected area, that is, a pinch zoom-in gesture. First and second touches of the pinch zoom-in gesture are all generated in the second touch screen 14, wherein the first touch is released within the second touch screen 14 and the second touch is released within the first touch screen 12. As another embodiment, the touch gesture 320 includes two touch drags which are simultaneously generated in the second touch screen 14 and move farther from each other in approximately opposite directions. As one example, at least one of the touch drags may start at one position of the second touch screen 14 and end at another position of the second touch screen 14. As another example, at least one of the touch drags may start at one position of the second touch screen 14 and end at one position of the first touch screen 12.

[0259] When the portable device 100 substantially simultaneously or sequentially detects two touches from the second touch screen 14 and substantially simultaneously detects that the detected touches are father from each other in opposite directions or continuously farther from each other in approximately opposite directions, the portable device 100 expands the first picture image 308a and displays the expanded the first picture image 308a to fully fill the first touch screen 12 and the second touch screen 14.

[0260] Although not illustrated, when a pinch zoom-out gesture including two touches which start at the first and second touch screens 12 and 14, respectively and are released on one touch screen, for example, the first touch screen 12 is detected while the first picture image 308a is displayed in the first and second touch screens 12 and 14, the portable device reduces the first picture image 308a and displays the reduced first picture image 308a to fully fill the first touch screen 12.

[0261] As illustrated in FIG. 9I, the portable device 100 detects a touch gesture 322 in a predetermined direction from the first picture image 308c displayed in both the first touch screen 12 and the second touch screen 14, for example, a flick or a touch drag in a direction from the second touch screen 14 to the first touch screen 12 (or opposite direction). Then, as illustrated in FIG. 9J, the portable device 100 replaces the first picture image 308c displayed in the first touch screen 12 and the second touch screen 14 with a second picture image 324 continuous to the first picture image 308c and displays the replaced second picture image 324 in response to the touch gesture 322. At this time, the first picture image 308c may be removed while sliding in a direction from the second touch screen 14 to the first touch screen 12 (or opposite direction) according to a direction and a speed of a motion of the touch drag 322. The second picture image 324 slides within the first touch screen 12 and the second touch screen 14 while following the first picture image 308c.

[0262] As a selectable embodiment, the touch drag 322 may be performed on one touch screen. As another selectable embodiment, the touch drag 322 may be performed over the two touch screens 12 and 14, that is, passing through the hinge.

[0263] The portable device can provide a familiar and a new home user interface such as a foldable wallet or compact powder through the display device including the first touch screen and the second touch screen arranged on at least one foldable panel. It is referred to as a pocket mode home screen in this specification. The portable device can provide the home screen as illustrated in FIG. 6 or the pocket mode home screen which will be described later according to a setting made when the portable device is manufactured or a setting of the user. As an embodiment, the pocket mode home screen may be usefully used in a double screen mode or an in-folded screen mode.

[0264] FIG. 10 (including FIGs. 10A to 10H) illustrates a user interface of the pocket mode home screen according to an embodiment of the present invention.

[0265] Referring to FIG. 10A, the first touch screen 12 displays areas 402, 404, 406, and 408 in a form of credit cards stored in a wallet which include some information on widgets or applications designated as the home screen and further displays a dock area 410 including icons of frequently used applications. Each of the areas 402, 404, 406, and 408 may have a form of the received credit card partially hidden by a graphic image embodying a slit for receiving the credit card in the wallet and may be vertically aligned with the received credit cards. The areas 402 to 408 display at least one of simple information provided by the widget or application and a shortcut key for executing a predetermined function. The simple information includes information which the user desires to first know through the application and may be updated in real time according to the application. For example, an area related to a message application can display whether a newly received message exists through a notice such as a flickering phrase of "NEW". As a selectable embodiment, the area 408 located in a bottommost part may have a form of the received credit card partially hidden by a slit of a diagonal line.

[0266] When a pre-designated touch gesture, for example, a tap gesture or a touch and hold is detected from one of the areas 402, 404, 406, and 408, the portable device displays an application of the corresponding area to occupy the whole of the first touch screen 12 or the second touch screen 14 or displays the application to occupy the whole of the first touch screen 12 and the second touch screen 14.

For example, the area 402 of a schedule widget includes today's date and time and titles of N schedules (for example, one or two schedules), the area 404 of a weather widget includes a current city, a current temperature, and a weather icon, and the area 408 of a business card widget includes a person's name in contact information, shortcut keys for connecting a call and / or sending a message, and a picture image. The picture image may be replaced with a default image.

[0268] As one embodiment, in response to the detection of a predetermined touch gesture, for example, a flick or a touch drag up from one of the areas 402, 404, and 408, the portable device expands the corresponding area in a form of the credit card partially withdrawn from a graphic image having a slit form. The expanded area includes more information in comparison with the corresponding widget or application. The expanded area may be reconstructed to an original size in response to the detection of a touch drag down from the enlarged area or the detection of a touch gesture from another area.

[0269] At least some of the areas (for example, the area 406) display shortcut keys for functions provided by the application while operating as the background. For example, the area 406 of a music play application displays a status bar showing an album image, a title, a musician, and a play status of a played music and additionally provides shortcut keys such as a previous music selecting key, a stop / play key, and a next music selecting key. When a tap gesture is detected from one of the shortcut keys, the music play application executes a function corresponding to the corresponding shortcut key as the background.

[0270] Referring to FIG. 10B, the portable device detects a pre-designated touch gesture 420, for example, a flick or a touch drag up from the area 402 of the schedule widget. Referring to FIG. 10C, in response to the detection of the touch gesture 420, the area 402 of the schedule widget is expanded in a top direction and then the expanded area 402a is displayed. The expanded area 402a displays time and titles of M schedules (for example, three or more schedules) and may further selectively display a weekly schedule according to an expanded length. The area 402 may be expanded in a top direction according to a movement of the touch gesture 420 and expanded to reach a terminus of the first touch screen 12 within a predetermined maximum size.

[0271] Referring to FIG. 10D, the portable device detects a pre-designated touch gesture 422, for example, a tap gesture or a touch drag from one of the shortcut keys and the status bar included in the area 406 of the music play application. Then, the music play application performs a function of playing music, playing previous music, stopping music, playing next music, or moving a play position. The area 406 of the music play application which operates as the background and does not require an area expansion may be embodied and displayed in a form of a sewed label, not the form of the received credit card.

[0272] Referring to FIG. 10E, the portable device detects a pre-designated touch gesture 424, for example, a flick or a touch drag up from the area 404 of the weather widget. In response to the detection of the touch gesture 424, the area 404 of the weather widget is expanded in a top direction and then the expanded area is displayed. The expanded area 404a may further display more detailed information on the weather, for example, additional information on today's weather and weekly weather. The area 404 of the weather widget may be expanded in a top direction according to a movement of the touch gesture 424 and expanded to reach a terminus of the first touch screen 12 within a predetermined maximum size. The area 404 of the weather widget may be expanded to cover at least some of the area 402 of the schedule widget which had been located in an upper part. As one embodiment, the area 404 cannot be expanded to exceed a predetermined maximum range. When an expanded length of the expanded area 404a reaches the maximum range, the expanded area 404a remains in an expanded state or is reconstructed to the area 404 in an original size.

[0273] Referring to FIG. 10F, the portable device detects a pre-designated touch gesture 426, for example, a flick or a touch drag up in a top direction from the area 408 of the business card widget.

[0277] FIG. 11 (including FIGs. 11A to FIG. 11F) illustrates a user interface of the home screen in the pocket mode according to another embodiment of the present invention.

[0278] Referring to FIG. 11A, the second touch screen 12 displays first areas 412 of applications designated as the home screen. The first areas 412 are displayed in a form of stored cards partially hidden by a graphic image in a form of a slit for receiving the cards within a wallet and include at least one of simple information (for example, two to three lines) provided by each application and a shortcut key 416 for executing a predetermined function. The simple information may be automatically updated in real time according to the application. As one embodiment, an area of a Social Networking Service (SNS) application can display whether an update is recently performed and display a part of contents of a recently updated message.

[0279] As a selectable embodiment, an area 414 of a photo gallery application which is one of the areas displayed in the second touch screen 12 can provide a predetermined number of thumbnail images. As an embodiment, the area 414 additionally includes a shortcut key for changing view modes of the thumbnail images. For example, the shortcut key includes a slider switch. Further, the thumbnail images may be scrolled according to an arranged direction of the thumbnail images within the area 414, for example, a motion direction and a speed of a touch gesture in a horizontal direction. As a selectable embodiment, since the area 414 of the photo gallery application does not need an area expansion, the area 414 may be embodied and displayed in a form of a sewed label, not the form of a received credit card.

[0280] The second touch screen 14 displays the first areas 412 including simple information on a predetermined number of applications, for example, three applications according to a setting of the home screen in the pocket mode. It is preferable that the first areas 412 are sequentially arranged in a vertical direction like the stored cards. For example, each of the first areas 412 includes a name of a graphic symbol of the application, information of one or two lines provided by the application, and an indicator showing an updated state of the application. When a pre-designated touch gesture (for example, a flick up or a touch drag up) is detected from each of the first areas 412, the corresponding first area 412 may be expanded to a top direction within a predetermined maximum size.

[0281] Referring to FIG. 11B, when a pinch gesture 430 for reducing the area, that is, a pinch zoom-out is detected from the first areas 412, each of the first areas 412 is reduced and reduced areas 412a of other applications are further displayed in a space within the second touch screen 14 generated by the reduced areas. That is, the reduced first areas 412 and the second areas 412a including the reduced areas of the other applications include more applications (for example, six or more applications) in comparison with the first areas 412, and accordingly display less information in comparison with the first areas 412, for example, only a name, a graphic symbol, and an update indicator of the application with one line.

[0282] As illustrated in FIG. 11C, when a touch gesture 432 in a predetermined direction, that is, a flick up / down or a touch drag up / down is detected from the second areas 412a, the portable device proceeds to FIG. 11D. Referring to FIG. 11D, the portable device displays reduced areas 412b of applications designated as the home screen in the pocket mode while scrolling the reduced areas 412b in a top direction or a bottom direction in response to the touch gesture 432.

[0283] When a pinch gesture 434 for expanding the area, for example, a pinch zoom-in is detected from the reduced areas 412b, the portable device proceeds to FIG. 11E. Referring to FIG. 11E, the reduced areas 412b according to the pinch gesture 434 are expanded to have an original size 412c and reduced areas (for example, topmost part and / or bottommost areas) of some applications by the area expansion are not displayed in the second touch screen 14 anymore. The areas 412c include a number of applications according to a basic setting of the home screen in the pocket mode, for example, five applications.

[0284] Referring to FIG. 11F, when a pre-designated touch gesture 436, for example, a flick in a top direction or a touch drag up is detected from one of the reduced areas 412a and 412b or the areas 412 and 412c having the original sizes, the corresponding area is expanded in a top direction and the expanded area 412d is displayed. The expanded area 412d may further display more detailed information of the corresponding application, for example, a recently uploaded image and more information on a recent activity. The expanded area 412d is generated by an expansion in a top direction according to a movement of the touch gesture 436 and may be expanded to reach a predetermined maximum range. According to a type of application, the expanded area 412d can provide at least one of a text input window having a size which can be included in the expanded area 412d and soft keys for predetermined functions together with the more detailed information.

[0285] As one example, the area in the form of the received credit card related to the message application is expanded by a touch drag up of the user and displays a miniaturized text input window and a transmission shortcut key in an area secured through the expansion.

[0286] As a selectable embodiment, when the pre-designated touch gesture 436, for example, a tap gesture is detected from a first area which is one of the areas 412, 412a, 412b, and 412c, the portable device expands the first area and displays the expanded first area in the second touch screen 14. At this time, the first area may be expanded in the same or similar sizes to those of all of the areas 412, 412a, 412b, and 412c or expanded to occupy the whole second touch screen 14. For example, the area in the form of the received credit card related to the social network service application is expanded by a tap gesture by the user and displays a predetermined number of recently received messages in an area secured through the expansion. The expanded area may include shortcut keys such as forward, reply, copy and the like on each message. The expanded area may be reconstructed to have an original size by a touch on another area or a pinch gesture.

[0287] As another selectable embodiment, when the pre-designated touch gesture 436, for example, a tap gesture is detected from the first area which is one of the areas 412, 412a, 412b, and 412c, the portable device displays an application corresponding to the first area in the whole second touch screen 14.

The portable device detects a pre-designated touch gesture 514, for example, a tap gesture or a touch and hold from one 504a of the position indicators 504a, 504c, 504d, 504f, and 504g displayed on the map area 502b displayed in the first touch screen 12. Then, in response to the detection of the touch gesture, the first touch screen 12 displays thumbnail images 520 of the registered images of the position indicator 504a in an area adjacent to the position indicator 504a 514as illustrated in FIG. 12D. The thumbnail images 520 may be displayed in the grid form or in the group view mode where at least some of the thumbnail images 520 overlap each other, and a name 520a of the registered image group of the position indicator 504a, for example, "A Castle" may be displayed together with the thumbnail images 520.

[0295] Referring to FIG. 12E, the portable device detects a touch gesture from one 504g of the position indicators 504a, 504c, 504d, 504f, and 504g displayed on the map area 502b displayed in the first touch screen 12 and displays thumbnail images 522 of registered images of the position indicator 504g in an area adjacent to the position indicator 504g. The thumbnail images 522 may be displayed in the grid form or the partially overlapping form, and a name 522b of the registered image group of the position indicator 504g, for example, "B Café" may be displayed together with the thumbnail images 522.

[0296] The second touch screen 14 provides a soft key 530 for selecting the view mode to change the view mode of the gallery area 506c into the group view mode or the grid view mode. For example, the soft key 530 includes a slider switch. When a touch of the user is detected from the slider switch and the slider switch moves to an icon indicating the view mode in a group form according to the touch, a gallery area 506e of the second touch screen 14 groups the registered thumbnail images of the position indicators 504a, 504c, 504d, 504f, and 504g included in the map area 502b displayed in the first touch screen 12 for each position and then displays the grouped thumbnail images. In the group view mode, the thumbnail images of each group may be displayed in a disordered form where the thumbnail images partially overlap each other.

[0297] Referring to FIG. 12F, the first touch screen 12 displays the map area 502b provided by the gallery map application. The map area 502b includes position indicators 504a, 504c, 504d, 504f, and 504g indicating a search result, a registered tourist attraction spot, or a position in which the picture image is registered. The second touch screen 14 includes a gallery area 506e in which thumbnail images of the picture images registered in positions included in the map area 502b are listed. The gallery area 506e displays at least some of the registered thumbnail images of the position indicators 504a, 504c, 504d, 504f, and 504g included in the map area 502b in the grid view mode or the group view mode.

[0298] When a pre-designated touch gesture 530, for example, a tap gesture or a touch and hold (that is, long tap) is detected from one (for example, the position indicator 504a) of the position indicators 504a, 504c, 504d, 504f, and 504g on the map area 502b, the first touch screen 12 displays a menu window 530a for selecting a path in an area adjacent to the position indicator 504a. The menu window 530a includes a start key and an arrival key. When a tap gesture 530b is detected from the start key of the menu window 530a, the gallery map application designates the position indicator 504a as a start position in response to the detection of the tap gesture 530b. At this time, the position indicator 504a may be changed to a conspicuous color, for example, red in order to be visually distinguished from other displayed position indicators 504c, 504d, 504f, and 504g.

[0299] Referring to FIG. 12G, when a pre-designated touch gesture 532, for example, a tap gesture or a touch and hold is detected from one (for example, the position indicator 504d) of the position indicators 504a, 504c, 504d, 504f, and 504g on the map area 502b displayed in the first touch screen 12, the first touch screen 12 displays a menu window 532a for selecting a path in an area adjacent to the position indicator 504d. The menu window 532a includes a start key and an arrival key. When a tap gesture 532b is detected from the arrival key of the menu window 532a, the gallery map application designates the position indicator 504d as an arrival position in response to the detection of the tap gesture 532b. At this time, the position indicator 504d may be changed to a conspicuous color, for example, red in order to be visually distinguished from other displayed position indicators 504c, 504f, and 504g.

[0300] When the start position or the arrival position is registered, the gallery map application displays a slide show control area 542 including information on the path from the start position to the arrival position in a lower part of the first touch screen 12. The slide show control area 542 may be displayed while partially covering the map area 502b.

[0301] Referring to FIG. 12H, when the start position 504a and the arrival position 504d are registered, the gallery map application displays a path 540 from the start position 504a to the arrival position 504d in a graphic line form in the map area 502b of the first touch screen 12. The path 540 is displayed along an actual road between the start position 504a and the arrival position 504d and may include at least one indicator 504c existing between the start position 504a and the arrival position 504d as an intermediate position. The slide show control area 542 displayed in the lower part of the first touch screen 12 may include a path trace bar 544 showing position indicators included in the path from the start position to the arrival position and movement states according to the path and a slide show view key 546 for selecting to initiate a slide show of the picture images included in the path 540. As another embodiment, the slide show control area 542 is displayed in response to the display of the path 540.

[0302] When a pre-designated touch gesture, for example, a tap gesture is detected from the slide show view key 546, the portable device removes the map area 502b from the first touch screen 12 and reproduces the slide show of the picture images registered in the positions included in the path 540 as illustrated in FIG. 12I. As one embodiment, the picture images are sequentially displayed to completely fill at least one of a horizontal width and a vertical width of the first touch screen 12 during the slide show. During the slide show, the path trace bar 544 of the slide show control area 542 includes a current slide indicator indicating a position of the picture image currently displayed in the first touch screen 12 and the slide show control area 542 provides a slide show stop key 548 for selecting to stop the slide show instead of the slide show view key 546.

[0303] As a selectable embodiment, the slide show control area 542 may be hidden from the first touch screen 12 during the slide show in order not to interrupt viewing of the slid picture images. The slide show control area 542 may be displayed again in a predetermined area of the first touch screen 12 for the slide show by, for example, detecting a predetermined touch gesture in the lower part of the first touch screen.

[0304] The portable device can display a task manager area including icons of a plurality of running applications through the display device including the first touch screen and the second touch screen arranged on one foldable panel. As another embodiment, the task manager area may include icons of favorite applications designated by the user. The task manager area may be disposed in pre-designated positions of the first touch screen and the second touch screen, for example, lower parts of the first touch screen and the second touch screen. That is, some of the icons of the task manager area are displayed in the lower part of the first touch screen and the remaining icons are displayed in the lower part of the second touch screen. The icons of the task manager area may be continuously disposed in the lower parts of the first and second touch screens.

[0305] FIG. 13 (including FIGs. 13A to 13J) illustrates a user interface of a task manager panel according to an embodiment of the present invention.

[0306] Referring to FIG. 13A, the first touch screen 12 displays a task screen 610 of a first application and the second touch screen 14 displays a task screen 612 of a second application. The task screens 610 and 612 have sizes to fill displayable areas of the first and second touch screens 12 and 14, display information executed by each application, and provide a user interface. Although a multi mode in which the first and second touch screens 12 and 14 display the task screens 610 and 612 of different applications is illustrated herein, an execution of the task manager which will be described below may be similarly applied to a case where the home screen or the application menu is displayed in at least one of the first and second touch screens 12 and 14 or the first and second touch screens 12 and 14 operate in the main-sub mode or the full mode.

[0307] The portable device detects a predetermined command or a user gesture for executing the task manager. The command or the user gesture includes, for example, at least one of an input of a physical button included in the housing of the portable device, a detection of a touch on a predetermined area within at least one of the first and second touch screens 12 and 14, a detection of a touch on a soft key provided through at least one of the first and second touch screens 12 and 14, and a control of a soft menu.

[0308] FIG. 13A illustrates an example of executing a task manager function by using one 600a of the physical buttons arranged in a second panel including the second touch screen 14. The button 600a for executing the task manager function may be, for example, a home button which is one of the touch detection typed physical buttons arranged in the second panel. When the portable device detects an input 602 of the home button 600a arranged in the second panel, for example, a tap gesture on the home button or a touch and hold, the portable device proceeds to FIG. 13B.

[0309] Referring to FIG. 13B, the portable device displays task manager panels 604a and 604b in predetermined positions of the first and / or second touch screens 12 or / and 14, for example, lower parts of the first and second touch screens 12 and 14 in response to the input 602. The task manager panels 604a and 604b form the task manager areas and are located in different touch screens 12 and 14 and disposed close to each other to be continuous. As another embodiment, the task manager panels 604a and 604b may be disposed in basically set positions or positions designated by the user, for example, upper parts of the first and / or second touch screens 12 and 14, a left part of the first touch screen 12, a right part of the second touch screen 14, and a right part of the first touch screen 12, and a left part of the second touch screen 14.

[0310] With displays of the task manager panels 604a and 604b, the first and second touch screens 12 and 14 replace the task screens 610 and 612 of the first and second applications with preview windows 610a and 612a of the first and second applications. The preview windows 610a and 612a have smaller sizes in comparison with the task screens 610 and 612 and may be displayed with a shadow in order to indicate a deactivated state in which the user interface such as a touch input or the like is not allowed.

[0311] In the shown example, the task manager panels 604a and 604b are divisibly displayed through two touch screens including the first touch screen 12 and the second touch screen 14 and include at least some of the icons of the running applications. For example, each of the task manager panels 604a and 604b may include a maximum of four icons which do not overlap each other. That is, the first task manager panel 604a includes icons of first to fourth running applications App#1 to App#4, and the second task manager panel 604b includes icons of fifth to eighth running applications App#5 to App#8. When the number of running applications exceeds a maximum number of icons which can be displayed in the task manager panels 604a and 604b, that is, when the number of running applications exceeds eight, the task manager panels 604a and 604b display only eight icons and may further display other icons by scrolling the displayed icons in response to a touch gesture.

[0312] As one embodiment, orders of the applications included in the task manager panels 604a and 604b are based on a last played time. Icons 610b and 612b of the first and second applications displayed in the first and second touch screens 12 and 14 before the execution of the task manger are located in first and second positions within the task manager panels 604a and 604b. When the number of running applications is smaller than a maximum number (for example, eight) of icons which can be included in the two task manager panels 604a and 604b, the icons of the running applications may be center-aligned from the hinge between the first and second touch screens 12 and 14. The center-aligned icons may move within the first task manger panel 604a or the second task manager panel 604b by a touch drag in a left direction or a right direction.

[0313] An end indicator 606 (for example, in an X form) for immediately ending the corresponding running application may be attached to each icon. A tap gesture is detected from the end indicator 606 attached to the application App#8 which is one of the displayed icons, the portable device ends the application App#8 of the corresponding icon. When a preview screen of the application App#8 is displayed within the first and / or second touch screens 12 and / or14, the preview screen of the application App#8 of the corresponding touch screen is replaced with one page of the home screen. When the preview screen of the application App#8 is not displayed within the first and / or second touch screens 12 and / or14, the application App#8 ends as the background.

[0314] Referring to FIG. 13C, the portable device detects a touch gesture 602a acting in parallel to a direction in which the icons are arranged on the first and / or second task manger panels 604a and 604b, for example, a flick or a touch drag in a left direction or a right direction and scrolls and displays the icons displayed in the first and second task manager panels 604a and 604b according to the touch gesture 602. The icons designated as the task manger may be scrolled while rotating. When passing though the hinge between the first and second touch screens 12 and 14 according to the touch gesture 602a, each of the icons may be displayed over the two touch screens 12 and 14. As another embodiment, when passing through the hinge according to the touch gesture 602a, each of the icons is displayed to skip the hinge without being divisibly displayed in the two touch screens 12 and 14.

[0315] Referring to FIG. 13D, the portable device detects a predetermined touch gesture 602b which starts at one 614b of the icons included in the first and / or second task manager panels 604a and / or 604b and heads for outsides of the first and / or second task manger panels 604a and / or 604b, for example, a touch drag which starts at the icon 614b of the application App#5 and is released at an area included in the first touch screen except for the first task manager panel 604a. As illustrated in FIG. 13E, the first touch screen 12 replaces the preview window 610a of the first application displayed in the first touch screen 12 with a preview window 614a of the application App#5 related to the icon 614b and displays the replaced preview window 614a in response to the detection of the touch drag 602b.

[0316] Referring to FIG. 13F, the portable device detects a touch drag 602c from an icon 616b of the application App#11 included in the first task manager panel 604a to an area included in the first touch screen 12 except for the first task manager panel 604a. The touch drag 602c starts at the icon 616b and is released at one point within an area included in the first touch screen 12 except for the first task manger panel 604a. As illustrated in FIG. 13G, the first touch screen 12 replaces the preview window 614a of the application App#5 with the preview window 616a of the application App#11 related to the icon 616b and displays the replaced preview window 616a in response to the detection of the touch drag 602c.

[0317] Although it has been illustrated that the replacement of the preview window made in the first touch screen 12 in FIGs. 13D to 13G, the preview window of the application corresponding to the icon included in the first task manager panel 604a may be drawn to the second touch screen 14 or the preview window of the application corresponding to the icon included in the second task manager panel 604b may be drawn to the first touch screen 12 according to a start position and a release position of the touch drag.

[0318] Referring to FIG. 13G, the portable device detects a pre-designated touch gesture 602d headed for an inside of the second task manager panel 604b displayed in the second touch screen 14, for example, a touch drag which starts at one position of the preview window 612a and is released at one position within the second task manager panel 604b from the preview window 612a of the second application displayed in the second touch screen 14. Then, the second touch screen 14 converts the preview window 612a to the icon 612b of the second application in response to the detection of the touch drag 602d and moves the icon 612b to the second task manager panel 604b according to the touch drag 602d. The icon 612b may be disposed between icons conventionally displayed within the second task manager panel 604b, that is, a position where the touch drag 602d is released.

[0319] Referring to FIG. 13H, as the icon 612b enters an area of the second task manager panel 604b according to the touch drag 602d, the second task manager panel 604b inserts the icon 612b between the previously displayed icons and displays them together. The icons displayed within the first and second task manager panels 604a and 604b may rearranged with the newly entered icon 612b. At this time, the second touch screen 14 replaces the preview window 612a of the second application with a preview window 618a of the running application App#10 and displays the replaced preview window 618a.

[0320] After the preview window 612a is removed according to the touch drag 602d, the second touch screen 14 may not display any preview window or task window except for the second task manager panel 604b. As a selectable embodiment, the second touch screen 14 can display a first page of the home screen after the preview window 612a is removed. Thereafter, when the preview window 616a of the first touch screen 12 is removed by the touch drag headed for the task manager panel 604a or 604b, the portable device displays the first page of the home screen in the first touch screen 12 and displays a second page of the home screen in the second touch screen 14. At this time, the first page of the home screen may be displayed together with a dock area in the first or second touch screen 12 or 14.

[0321] Referring to FIG. 13I, the portable device detects a predetermined command or user gesture for ending the task manager while the preview windows 616a and 620a of the applications are displayed in the first and second touch screens 12 and 14.
