Abstract: A mobile computing device runs multiple activities concurrently and provides at least two modes for interacting with the activities. The user may toggle between the modes as desired. In a full-screen mode, one activity occupies substantially an entire display screen. In a windowed mode, the activity is visible within a window, and a portion of at least one other window is also visible. In the windowed mode, the user can cause windows to move, thereby changing focus from one activity to another. For example, the window having focus can be moved off the screen, to be replaced by a new window that is then given focus. The windows are ordered in a sequence and move in concert with one another; pushing one window off one edge of the screen causes a new window to appear at the opposite edge. A persistent positional relationship can be established among windows.

Abstract: In an electronic device capable of running multiple software applications concurrently, applications, documents, cards, or other activities can be selected for hibernation so as to free up system resources for other activities that are in active use. A determination is made as to which activities should hibernate, for example based on a determination as to which activities have not been used recently or based on relative resource usage. When an activity is to hibernate, its state is preserved on a storage medium such as a disk, so that the activity can later be revived in the same state and the user can continue with the same task that was being performed before the activity entered hibernation.

Abstract: In various embodiments, a card metaphor is established, in which each activity can be represented within an area of the screen referred to as a card. In various embodiments, any of several display modes are available for viewing, interacting with, manipulating, initiating, and dismissing cards. A persistent positional relationship can be established among cards, represented by a one-dimensional sequence. Newly opened cards are generally placed at the end of the sequence, although a new card that bears a relationship to an already open card may, in some embodiments, be placed adjacent to the already open card. In various embodiments, cards may be grouped, with such groups being represented as stacks of cards or by other visually distinctive means.

Abstract: A user of a mobile computing device may provide a first user preference for a first type of event and a second user preference for a second type of event, and the mobile computing device may detect an event comprising reception of the first type of event or the second type of event. The mobile computing device may present, along an edge of a touch-sensitive display of the mobile computing device, a banner alert in response to detecting the first type of event, and may present, on the touch-sensitive display, a pop-up notification in response to detecting the second type of event. The mobile device may dismiss the banner alert based on a user swiping the banner alert off the touch-sensitive display.

Abstract: A computing device includes at least one processor; a display device; and at least one module. The at least one processor may be operable to store data that defines a plurality of discrete graphical elements (DGE's), wherein the plurality of DGE's includes at least one root DGE, and wherein dismissal of the root DGE causes dismissal of all of the plurality of DGE's. The at least one module may be operable to output a particular DGE of the plurality of DGE's; output, for display, the root DGE, responsive to receiving a first indication of user input of a particular input type; and ignore the second indication of user input to refrain from dismissal of the root DGE, responsive to receiving a second indication of user input of the particular input type within a threshold time duration that is initiated responsive to outputting the root DGE.

Abstract: A device that includes one or more processors may determine a configuration of a display region of the device. The device may also receive a request to perform an animation of a virtual object within the display region. The request may be indicative of a given duration for the animation based on the animation being performed within a given display region having a given configuration. The device may also modify the given duration to determine an adjusted duration for the animation based on a comparison between the configuration and the given configuration. The device may also perform the animation within the display region based on the animation having the adjusted duration.
