Abstract: A multi-screen user device and methods for logically controlling the display behavior of applications and other displayable data are disclosed. Specifically, when a dual-screen application is displayed to the primary and secondary screens of a device the dual-screen application can be minimized to a single screen by closing the device. When the device is reopened, the minimized dual-screen application is maintained in a minimized state on the screen to which it was minimized. Specific rules can be implemented to determine whether the dual-screen application will be maximized to run on the primary and secondary screens of a device upon reopening.

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: 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: Embodiments are described for handling focus when a gesture is input in a multi-screen device. In embodiments, a first image displayed on a first touch sensitive display of a first screen may be currently in focus. In embodiments, the gesture is a tap on a second touch sensitive display of the device. In response to the gesture, focus is changed from the first image on the first touch sensitive display to the second touch sensitive display.

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 the user with the ability to selectively change the orientation of one display and leaving the other display unaffected when the user has two applications or desktops displayed on respective screens. The user can therefore selectively change on a screen-by-screen basis the orientation of any desktops or applications displayed.
