Abstract: A seamless cross-environment workflow is provided in a multi-operating system computing environment. The multi-operating system computing environment may include a mobile operating system and a desktop operating system running concurrently and independently on a mobile computing device. Two or more application programs, running in independent operating systems, share user interaction state information including user data, user settings, and/or application context information. Interaction state information may be shared for applications that are used primarily to access and edit local user content as well as applications that communicate to a remote server or access and navigate other remote content (e.g., Internet-based application, browser, etc.). The mobile computing device may be a smartphone running the Android mobile operating system and a full desktop Linux distribution on a modified Android kernel.

Abstract: A multi-screen user device and methods for controlling data displayed are disclosed. The data displayed by the multiple screens of the device is dependent on the physical orientation of the device, whether the content for an application is displayed across a plurality of the multiple screens, and whether the data being displayed for the application originated from a single-screen application or a multi-screen application.

Abstract: A multi-display device is adapted to be dockable or otherwise associatable with an additional device. In accordance with one exemplary embodiment, the multi-display device is dockable with a smartpad. The exemplary smartpad can include a screen, a touch sensitive display, a configurable area, a gesture capture region(s) and a camera. The smartpad can also include a port adapted to receive the device. The exemplary smartpad is able to cooperate with the device such that information displayable on the device is also displayable on the smartpad. Furthermore, any one or more of the functions on the device are extendable to the smartpad, with the smartpad capable of acting as an input/output interface or extension of the smartpad. Therefore, for example, information from one or more of the displays on the multi-screen device is displayable on the smartpad.

Abstract: Embodiments are described for minimizing application windows displayed on one or more displays of a multi-screen device. A device may display a dual screen application which is displayed across both screens. Depending upon which screen is used to launch (or reopen) an application, the dual screen application may be minimized to the other screen.

Abstract: Methods and devices for the display of virtual keyboards are provided. More particularly, virtual keyboards that include selectable sets of virtual keys that can be selected or changed through direct input by a user are provided. The user input can include a touch screen input or gesture applied to an area of a display in which a selectable set of virtual keys is presented. The touch screen input or swipe can cause the displayed selectable set of virtual keys to be replaced by an alternate selectable set of virtual keys.

Abstract: Embodiments are described for handling the launching of applications in a multi-screen device. In embodiments, a first touch sensitive display of a first screen receives input to launch an application. In response, the application is launched and a window of the first application is displayed on the first display. A second touch sensitive display of a second screen receives input to launch a second application. In response, the second application is launched and a second window of the second application is displayed on the second display. In embodiments, when an application is launched, it displays the view of the application (whether on the first touch sensitive display or the second touch sensitive display) that was displayed when the application was last closed.

Abstract: A dual display communication device includes a gesture capture region to receive a gesture, a first touch sensitive display to receive a gesture and display displayed images (such as a desktop or window of an application), and a second touch sensitive display to receive a gesture and display displayed images. Middleware receives a gesture, the gesture indicating that a displayed image is to be moved from the first touch sensitive display to the second touch sensitive display, such as to maximize a window to cover portions of both displays simultaneously; in response and prior to movement of the displayed image to the second touch sensitive display, moves a transition indicator from the first touch sensitive display to the second touch sensitive display to a selected position to be occupied by the displayed image; and thereafter moves the displayed image from the first touch sensitive display to the second touch sensitive display to the selected position.

Abstract: Systems and methods are provides for displaying a desktop for a multi-screen device in response to opening the device. The window stack can change based on the change in the orientation of the device. The system can receive an orientation change that transitions the device from a closed state to an open state. A previously created in the stack can expand over the area of the two or more displays comprising the device when opened. A desktop expands to fill the display area and be displayed on the second of the displays after the device is opened.

Abstract: Cross-environment rendering and user interaction support provide a seamless computing experience in a multi-operating system computing environment. Cross-environment rendering provides real-time display of applications running in a mobile operating system to be displayed within an environment of a desktop operating system. The mobile operating system and the desktop operating system may be running concurrently and independently on a shared kernel of a mobile computing device. A graphics server of the mobile operating system tears down and rebuilds the rendering context for each application as it composites the surface information. The rendering context may be established to match the resolution of the associated display, so that graphics will be appropriately rendered for that resolution. The mobile computing device may be a smartphone running the Android mobile operating system and a full desktop Linux distribution on a modified Android kernel.

Abstract: Systems and methods are provides for creating a window stack for a multi-screen device. The stack is an arrangement of an active window and at least one other active or inactive window for at least one of the two displays. The system can receive activation of a window in the device. Upon activation of the window, the system can determine a display associated with the active window and can determine a position in the window stack for the active window. Then, the system can generate a logic data structure for the active window to describe the position of the active window in the window stack.

Abstract: The disclosed method and device are directed to navigation, by a dual display communication device, through display objects.

Abstract: Embodiments are described for handling focus when a gesture is input in a multi-screen device. In embodiments, the gesture indicates that two images, one that is in focus, swap positions. In response to receiving the gesture, the image in focus is moved from a first display of a first screen to a second display of a second screen. After the images are swapped, the focus is maintained on the image that originally had the focus.

Abstract: Methods and devices for selectively presenting a virtual keyboard are provided. More particularly, a change in the operating mode of a multiple screen device between a multiple screen operating mode and a single screen operating mode can be determined. Moreover, a change in the operating mode can effect a change in a presentation of a virtual keyboard. More particularly, a presentation of a virtual keyboard can be discontinued in response to a change in the operating mode of the device, where an application that had keyboard focus prior to the change is, after the change, no longer in view of the user.

Abstract: A multi-screen user device and methods for performing a copy-paste operation using finger gestures are disclosed. A first finger gesture is used to select a display area from which data is to be copied. Subsequently, a drag finger gesture is used to identify where the data that is to be pasted. The drag may extend across a non-display boundary between a first and second display screen of the multi-screen device.

Abstract: A dual-screen user device and methods for revealing a combination of desktops on single and multiple screens are disclosed. A determined number of desktops and/or running applications can be selectively displayed on dual screen displays conditioned upon inputs received and the state of the device. Desktop displays and applications can be selectively shifted between the screens by user gestures, and can be moved off of the screens by other user gestures and therefore hidden. The hidden desktops and screens however can be re-displayed by yet another gesture. The desktops and applications are arranged in a window stack that represents a logical order of the desktops and applications allowing a user with an intuitive ability to manage multiple applications/desktops running simultaneously. Visual indicators can be used on the displayed applications and desktops enabling a user to maximize a display on multiple screens or to minimize them on a single selected screen.

Abstract: A dual-screen user device and methods for revealing a combination of desktops on single and multiple screens are disclosed. A number of desktops and/or running applications can be selectively displayed on dual screen displays conditioned upon inputs received and the state of the device Desktop displays and applications can be selectively shifted between the screens by user gestures or moved off of the screens by other user gestures and therefore hidden. The hidden desktops and screens however can be re-displayed by yet another gesture. The user gestures prevent the user from having to open and close the running desktops and applications, or to execute other user commands that otherwise result in a laborious effort by the user to manage the multiple desktops and applications. One user gesture or input enables a user to change an order of the window stack by simply re-launching a selected desktop or application.

Abstract: Systems and methods are provides for displaying a second window for a multi-screen device in response to opening the device. The window stack can change based on the change in the orientation of the device. The system can receive an orientation change that transitions the device from a closed state to an open state. A previously created, but inactive, window in the stack can be displayed on one of the two or more displays comprising the device when opened. The previously created window become active to be displayed on the second of the displays after the device is opened.

Abstract: Methods and devices for selectively presenting a virtual keyboard are provided. More particularly, upon the receipt of instructions to launch an application, a determination can be made as to whether the application is associated with instructions to receive keyboard focus on launch. If the application is to receive keyboard focus on launch, a virtual keyboard is presented together with the newly launched application. Where an application is not set to receive keyboard focus on launch, a virtual keyboard that is presented when instructions to launch the application are received can be dismissed.

Abstract: A dual-screen user device and methods for revealing a combination of selected desktops and applications on single and dual screens are disclosed. Desktops and applications can be shifted between screens by user gestures, and/or moved off of the screens and therefore hidden. Hidden desktops and screens can be re-displayed by other gestures. The desktops and applications are arranged in a window stack that represents a logical order of the desktops and applications providing a user with an intuitive ability to manage multiple applications/desktops running simultaneously. One embodiment provides an annunciator window extending across both screens in a dual screen configuration. The annunciator window provides alerts, notifications, and statuses of the device in an increased area thereby enhancing viewability of the information in the window. The annunciator window can be expanded over a selected screen to view full contents of the window without having to minimize or close running applications.
