A system and method for a back stack in a multi-application environment, wherein the method comprises adding an entry to a last-in-first-out (LIFO) data structure, the entry comprising application state information descriptive of an application state of a software application and display state information descriptive of a display state of a display surface of a touch screen device, adjusting a LIFO data structure pointer to reflect a revised LIFO data structure state resulting from the adding the entry, receiving a back button actuation indication, in response to receiving the back button actuation indication, restoring the software application to the application state and restoring the display surface to the display state, and readjusting the LIFO data structure pointer to reflect an original LIFO data structure state that existing prior to the adding the entry.

System and method for a back stack in a multi-application environment

A touch screen may emphasize the display of objects near the tip of a user input instrument located near the surface of the touch screen but not touching the touch screen. The objects may consist of words and the emphasis may consist of highlighting. The user input instrument may be a finger of a user or an electronic pen. As the user input instrument is moved, the objects emphasized may change. A user may select objects on a touch screen by entering into object-selection mode and moving the user input instrument along the surface of the touch screen. An initial touch of the user input instrument to the surface of the touch screen may select a nearest object or objects. As the user input instrument is moved along the surface, the selection of objects may change based upon the movement.

Display of objects on a touch screen and their selection

An information handling system includes a primary integrated display device housing and a second integrated display device housing attached via a hinge and a processor to determine a first relative orientation of the primary integrated display device housing to the second integrated display device housing from a plurality of orientation sensors. The processor further determines a working software application context by detecting at least a first software application running on the information handling system wherein the working software application context further includes an operating state rank of the first software application relative to other software applications. The processor detects a required user input to the first software application and alters a location of a first software application display window and a virtual input softkey on a display device based on the first relative orientation and displaces second software application window of a second software application with a previously-higher the operating state rank.

System and method for positioning an application window based on usage context for dual screen display device

A system and method is provided for, on a multi-display touch screen apparatus executing a single-display application program, establishing an interface between the multi-display touch screen apparatus and the single-display application program, the interface comprising a virtual display and virtual sensors, obtaining sensor data from physical sensors of the multi-display touch screen apparatus, providing at least a first subset of the sensor data to the single-display application program via the virtual sensors of the interface, specifying to the single-display application program virtual display parameters which emulate single display parameters of a single-display touch screen apparatus, receiving at the virtual display of the interface a window image to be displayed from the single-display application, and displaying the window image on at least a first one of multiple displays of the multi-display touch screen apparatus.

System and method for using single-display application programs on a multi-display device

An information handling system includes a primary integrated display device and a second integrated display device attached via a hinge and a processor. The processor determines a first relative orientation of the primary integrated display device to the second integrated display device from orientation sensors. The processor further determines a working software application context by detecting at least a first software application running on the information handling system wherein the working software application context further includes an operating state rank of the first software application relative to other software applications.
