A common distributed systems architecture typically divides computational processing between local (a.k.a. client) and remote (a.k.a. server) components, with communications via a wired or wireless communications network. In designing such systems, two processes for implementing the local user interface are typical. In one process, the user interface is a core subsystem of the local component, and can only be changed by replacing the whole local component. In the other process, the local user interface is specified by the remote component, typically using a “markup” language.
A personal computer Web browser demonstrates a hybrid of these two processes. The browser is the local component of the system. The user interface of the browser itself is “built in” and can only be changed by updating the browser software. The user interface of the World Wide Web services, however, are defined by HTML and Flash markup code, sent from various Web servers (a.k.a. remote components). That is, the user interfaces of the Web services comprise remote components.
A user interface determined by a local component is free of issues such as latency and resource efficiency, but a user interface determined by a remote component is more easily controlled and updated.
A distributed computational system, with local and remote processing components, is configured to provide a user interface of the local component that is stored in the local component but is controlled and updated by the remote component. This configuration ensures operational responsiveness from the local component but retains control and updating in the remote component.
Other features and advantages of the present invention should be apparent from the following description of the preferred embodiment, which illustrates, by way of example, the principles of the invention.

Unlike a typical distributed system cache (e.g. a cache for a Web browser), the information within the local user interface sub-component 105 is controlled by the remote processing component 110, not the local processing component 100. This ensures that the local user interface 105 can always be displayed correctly. This configuration ensures that a provider of the user interface 105 has sole control over the “look and feel” of the user interface, without latency issues and the like noted previously.

Exemplary Implementations
The systems and methods described above may be implemented in a number of ways. One such implementation includes various electronic components. For example, units of the various systems may, individually or collectively, be implemented with one or more Application Specific Integrated Circuits (ASICs) adapted to perform some or all of the applicable functions in hardware. Alternatively, the functions may be performed by one or more other processing units (or cores), on one or more integrated circuits. In other embodiments, other types of integrated circuits may be used (e.g., Structured/Platform ASICs, Field Programmable Gate Arrays (FPGAs), and other Semi-Custom ICs), which may be programmed in any manner known in the art. The functions of each unit may also be implemented, in whole or in part, with instructions embodied in a memory, formatted to be executed by one or more general or application-specific processors.
The computational system 700 is shown comprising hardware elements that can be electrically coupled via a system bus 726 (or may otherwise be in communication, as appropriate). The hardware elements can include one or more central processor units (CPUs) 702, including without limitation one or more general-purpose processors and/or one or more special-purpose processors (such as communication processing chips, graphics acceleration chips, and/or the like); one or more input devices 704, that can include, without limitation, a mouse, a keyboard, and/or the like; and one or more output devices 706, which can include without limitation a display device, a printer, audio device, and/or the like.
The computational system 700 may further include (and/or be in communication with) one or more storage devices 708, which can comprise, without limitation, local and/or network accessible storage and/or can include, without limitation, a disk drive, a drive array, an optical storage device, solid-state storage device such as a random access memory (“RAM”), and/or a read-only memory (“ROM”), which can be programmable, flash-updateable, and/or the like. The computational system 700 might also include a communications subsystem 714, which can include without limitation a modem, a network card (wireless or wired), an infra-red communication device, a wireless communication device and/or chipset (such as a Bluetooth device, an 802.11 device, a WiFi device, a WiMax device, cellular communication facilities, etc.), and/or the like. The communications subsystem 714 may permit data to be exchanged with a network 715, and/or any other devices described herein. The network 715 may comprise a local area network (LAN) or a network such as the Internet, or a combination. In many embodiments, the computational system 700 will further include a working memory 718, which can include a RAM or ROM device, as described above. The system may optionally include processing acceleration 716 to assist with processing, such as arithmetic computations, graphical computations, and the like.
The computational system 700 also may comprise software elements, shown as being currently located within the working memory 718, including an operating system 724 and/or other code, such as one or more application programs 722, which may comprise computer programs performing tasks and operations described above, and/or may be designed to implement methods in accordance with the invention and/or configure systems in accordance with the invention, as described herein. Merely by way of example, one or more procedures described with respect to the method(s) discussed above might be implemented as code and/or instructions executable by a computer (and/or a processor within a computer). In one embodiment, the data generating and presenting operations are implemented as application programs 722. In the description herein, references to “interface” and “processor” and “application” should be understood as referring to hardware, software, and combinations of the two, either as independent components (hardware, software, and/or both) for each interface, processor, or application, or as integrated components combined with one or more other components.
A set of these instructions and/or code may be stored on a computer readable storage medium 710b. In some embodiments, the computer readable storage medium 710b may comprise the storage device(s) 708 described above. In other embodiments, the computer readable storage medium 710b might be incorporated within the computer system. In still other embodiments, the computer readable storage medium 710b might be separate from the computer system (i.e., it may be a removable readable medium, such as a compact disc, etc.), and or might be provided in an installation package, such that the storage medium can be used to program a general purpose computer with the instructions/code stored thereon. These instructions might take the form of executable code, which is executable by the computational system 700 and/or might take the form of source and/or installable code, which, upon compilation and/or installation on the computational system 700 (e.g., using any of a variety of generally available compilers, installation programs, compression/decompression utilities, etc.), then takes the form of executable code. In these embodiments, the computer readable storage medium 710b may be read by a computer readable storage media reader 710a.
It will be apparent to those skilled in the art that substantial variations may be made in accordance with specific requirements. For example, customized hardware might also be used, and/or particular elements might be implemented in hardware, software (including portable software, such as applets, etc.), or both. Further, connection to other computing devices such as network input/output devices may be employed.
In some embodiments, one or more of the input devices 704 may be coupled with an audio interface 730-1. The audio interface 730-1 may be configured to receive audio information by interfacing with a microphone, instrument, digital audio device, or other audio signal or file source. In other embodiments, one or more of the input devices 704 may be coupled with an optical interface 730-2. The optical interface 730-2 may be configured to receive optical information 731-2 by interfacing with a camera, scanner, digital imaging device, or other digital image source.
Further, in some embodiments, one or more of the output devices 706 may be coupled with an audio output device 707-1. The audio output device 707-1 may be configured to output audio signal data generated by embodiments of the invention to one or more systems or devices capable of handling that data, for example a speaker, audio component, digital-to-analog converter, compact disc writer, and the like. In other embodiments, one or more of the output devices 706 may be coupled with a data output device 707-2. The data output device 707-2 may be configured to output data generated by embodiments of the invention to one or more systems or devices capable of handling that data, for example data processing software, publication systems, file storage devices, and the like.
In one embodiment, the invention employs local and remote computer systems (such as the computational system 700) to perform methods of the invention. According to a set of embodiments, some or all of the procedures of such methods are performed by the computational system 700 in response to the processor 702 executing one or more sequences of one or more instructions (which might be incorporated into the operating system 724 and/or other code, such as an application program 722) contained in the working memory 718. Such instructions may be read into the working memory 718 from another machine-readable medium, such as one or more of the storage device(s) 708 (or 710). Merely by way of example, execution of the sequences of instructions contained in the working memory 718 might cause the processor(s) 702 to perform one or more procedures of the methods described herein.
The terms “machine readable medium” and “computer readable medium,” as used herein, refer to any medium that participates in providing data that causes a machine to operate in a specific fashion. In an embodiment implemented using the computational system 700, various machine-readable media might be involved in providing instructions/code to processor(s) 702 for execution and/or might be used to store and/or carry such instructions/code (e.g., as signals). In many implementations, a computer readable medium is a physical and/or tangible storage medium. Such a medium may take many forms, including but not limited to, non-volatile media, volatile media, and transmission media. Non-volatile media includes, for example, optical or magnetic disks, such as the storage device(s) (708 or 710). Volatile media includes, without limitation, dynamic memory, such as the working memory 718. Transmission media includes coaxial cables, copper wire, and fiber optics, including the wires that comprise the bus 726, as well as the various components of the communication subsystem 714 (and/or the media by which the communications subsystem 714 provides communication with other devices). Hence, transmission media can also take the form of waves (including, without limitation, radio, acoustic, and/or light waves, such as those generated during radio-wave and infra-red data communications).
Common forms of physical and/or tangible computer readable media include, for example, a floppy disk, a flexible disk, hard disk, magnetic tape, or any other magnetic medium, a CD-ROM, any other optical medium, punchcards, papertape, any other physical medium with patterns of holes, a RAM, a PROM, an EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave as described hereinafter, or any other medium from which a computer can read instructions and/or code.
Various forms of machine-readable media may be involved in carrying one or more sequences of one or more instructions to the processor(s) 702 for execution. Merely by way of example, the instructions may initially be carried on a magnetic disk and/or optical disc of a remote computer. A remote computer might load the instructions into its dynamic memory and send the instructions as signals over a transmission medium to be received and/or executed by the computational system 700. These signals, which might be in the form of electromagnetic signals, acoustic signals, optical signals, and/or the like, are all examples of carrier waves on which instructions can be encoded, in accordance with various embodiments of the invention.
The communications subsystem 714 (and/or components thereof) generally will receive the signals, and the bus 726 then might carry the signals (and/or the data, instructions, etc. carried by the signals) to the working memory 718, from which the processor(s) 702 retrieves and executes the instructions. The instructions received by the working memory 718 may optionally be stored on a storage device 708 either before or after execution by the processor(s) 702.
The present invention has been described above in terms of a presently preferred embodiments so that an understanding of the present invention can be conveyed. There are, however, many configurations for providing user interface processing not specifically described herein but with which the present invention is applicable. The present invention should therefore not be seen as limited to the particular embodiments described herein, but rather, it should be understood that the present invention has wide applicability with respect to user interface processing generally. All modifications, variations, or equivalent arrangements and implementations that are within the scope of the attached claims should therefore be considered within the scope of the invention.
