Abstract: An intuitive technique for inputting user gestures into a handheld computing device is disclosed allowing a user to better manipulate different types of screen display presentations, such as desktops and application windows, when performing tasks thereon, wherein a window stack for application windows and/or desktops can be navigated and sequentially displayed according to the window stack ordering without disturbing or changing this ordering.

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.

Abstract: The present disclosure is directed to methodologies and devices for handling the display of hierarchically related windows in a single-screen communication device.

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 multi-screen user device and methods for performing a drag and drop 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.
