## Background
FIELD OF THE DISCLOSURE
The present disclosure relates to information handling systems and more particularly to display devices for information handling systems.
BACKGROUND
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements can vary between different applications, information handling systems can also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information can be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems can include a variety of hardware and software components that can be configured to process, store, and communicate information and can include one or more computer systems, data storage systems, and networking systems.
Typical information handling systems use one or more standard interface devices, such as a keyboard or a mouse, to allow a user to interact with an application program. However, as application programs grow in complexity, providing users with a number of different options, the ability of a user to perform tasks with these conventional interface devices diminishes. For example, to perform a particular task, the user may have to access several menus, sub-menus, and option boxes. Such interaction can become cumbersome, resulting in a poor user experience. Some application programs provide a toolbox or similar interface that allows a user to perform a task or select an option by actuating a virtual button. However, as the number of options grows so too does the number of buttons, limiting display space for other information. Accordingly, an improved interface device for an information handling system would be useful.

FIG. 1 illustrates a block diagram of an exemplary embodiment of an information handling system 100. In one form, the information handling system 100 can be a computer system such as a personal computer. As shown in FIG. 1, the information handling system 100 can include a first physical processor 102 and a memory 104. In an embodiment, the information handling system 100 can support multiple processors and can allow for simultaneous processing of multiple processors and support the exchange of information within the system.
The memory 104 can be a volatile memory, such as a random access memory (RAM), or non-volatile memory such as flash memory or a hard disk. The memory 104 is configured to store application programs, such as application 110. The information handling system 100 also includes touch screen displays 106 and 108, which are each connected to the processor 102.
The application 110 includes instructions to manipulate the processor 102 to execute designated tasks. To illustrate, the application 110 can control the processor 102 to provide display information to each of the touch screen devices 106 and 108. The touch screen devices 106 and 108 are configured to display the provided display information. In an embodiment, the display information provided to each touch screen device represents a different input screen for the application 110. As used herein, an input screen is a screen configured for display at a touch screen device that allows a user, by interacting with the touch screen device, to provide input information for an application. Interaction can include touching locations on the touch screen device, performing touch gestures (e.g. movement of a finger across the touch screen device), multi-touch gestures (e.g. movement of more than one finger across the touch screen device, where the particular input is based on the movement of each finger), and the like.
The touch screen devices 106 and 108 are further configured to, in response to interaction at the device, provide information indicative of the interaction to the processor 102. Based on the interaction, the processor 102 can take appropriate action including performing a requested task, changing information stored at the memory 104, and the like. In an embodiment, in response to an interaction at one of the touch screen devices 106 and 108, the processor 102 changes the display information provide to one or more of the touch screen devices. Accordingly, interaction at one of the touch screen devices 106 and 108 can change the information displayed at the other device.
The operation of the information handling system 100 can be better understood with reference to exemplary operations. In one embodiment, the application 110 is a game program, and provides information for display at the touch screen device 106 and 108 representing different game views. As used herein, a game view refers to a display related to a particular aspect of a game. Thus, in a role-playing game or shooter game, touch screen device 106 can display the game environment visible to a player's character, while the touch screen 108 simultaneously displays an inventory screen that displays equipment, spells, or other options available for the character. Further, a user can independently interact with each touch screen device to provide independent inputs to the game program. Thus, a user could interact with the touch screen device 106 to select a target to attack or an object to pick up, and interact with the touch screen device 108 to select an inventory item, such as a weapon or spell to attack with. The application 110, executing at the processor 102, interprets the interactions at each of the touch screen devices and 108 and takes the appropriate action, including updating state variables and other information so that the game state reflects the interactions.
In another embodiment, the application 110 is a game program that displays different game environment views at each of the touch screen devices 106 and 108. For example, the application 110 can provide information to the touch screen device 106 so that a detailed map of a particular game location is displayed, and provide information to the touch screen device 108 so that a less detailed map (e.g. a “world map”) of a broader portion of the game environment is displayed. User interactions at one of the touch screen devices 106 and 108 can change the display in the other. For example, a user could interact with the touch screen device 108 to select a particular portion of the game environment to view. In response to this interaction, the application 110 can change the display information provided to the touch screen device 106 so that it displays a detailed view of the selected portion.
By separating game views between the touch screen 106 and touch screen 108, the user experience with application 110 can be enhanced. For example, by displaying particular game options at touch screen 108, the available area to display a game environment or other game screen at touch screen device 106 is increased. In addition, multiple options and input screens can be displayed simultaneously, improving the flexibility with which a player can interact with the game.
In another embodiment, the application 110 is a graphics program, such as a drawing program, that allows a user to create graphical objects. Accordingly, the application 110 can provide information to the touch screen device 106 to display a virtual canvas. The user can interact with the touch screen device 106 to draw items directly on the screen. In response, the touch screen device 106 provides information to the application 110 representing the interactions, allowing the application to create and change program objects representing the drawn items. In addition, simultaneous to displaying the virtual canvas at the touch screen device 106, the application 110 can display a virtual “toolbox” at the touch screen device 108. The virtual toolbox provides a set of options to determine how a user's interactions with the virtual canvas will be manifested. For example, the virtual toolbox can provide a set of brush options, with each brush associated with a different pixel size. Accordingly, if a brush is selected, lines drawn by a user on the virtual canvas at the touch screen 106 will be sized based on the pixel size associated with the selected brush. The user can select a particular option in the virtual toolbox by interacting with the touch screen device 108. For example, the options can be displayed as a set of virtual buttons, and a user touch the screen of the touch screen device 108 to actuate a button, thereby selecting the associated option. In response to selection of an option, the touch screen device 108 provides information to the application 110 indicating the selection. Based on the selection, the application 110 can change the information displayed at the touch screen device 106. For example, selection of a particular option can change the color, format, font, or other attribute of an object displayed at the touch screen device 106.
