Second, the results of the request are transmitted in a hidden format from the host to the remote computer. Third, the results are remotely processed in response to user input. Last, the processed results are dynamically displayed. Client-side processing is preferably used instead of server-side processing to enable the user to quickly access and adjust information dynamically and in real time without server delays.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a system and method for processing data, and in particular, to a system and method for adjusting data values in real time in response to remote user input.

2. Related Art

Quick and easy interaction between a server and a client user is desirable, especially for systems with bandwidth limitations. For example, the Internet utilizes a server-client system. Many client users with Internet access have bandwidth limitations. For example, during interaction with the World Wide Web, these client users typically encounter server processing every time the user makes a request. Constant server processing bogs down the server, delays user Internet navigation and creates an unpleasantly slow Internet experience for the user.

For example, many servers have systems that provide access to database information. One such system is a used car online classified database. After the user makes an initial request, the server provides results related to the request. However, if the user desires to modify, adjust, limit, etc. the results, the server typically must be re-accessed and a new request is submitted as a database query. As a result, the user is required to navigate sometimes through several layers of information. Thus, these systems are slow, do not allow real time user interaction and require undue processing. Therefore, what is needed is an effective and efficient technique for adjusting data values in real time in response to remote user input. What is also needed is a system and method that utilizes client-side processing instead of server-side processing for data processing to avoid lengthy server reloading.

Whatever the merits of the above mentioned systems and methods, they do not achieve the benefits of the present invention.

SUMMARY OF THE INVENTION

To overcome the limitations in the prior art described above, and to overcome other limitations that will become apparent upon reading and understanding the present specification, the present invention is embodied in a system and method for dynamically adjusting data values in response to remote user input. Namely, the system and method provides the remote user with real time interaction of data values, such as a set of results, produced by a host system. As such, the user can dynamically adjust the set of results from a remote location. The system and method of the present invention preferably utilizes client-side processing to achieve real time interaction.

Specifically, first, a user requests information from a remote computer and then results of the requested information are collected at a host computer. Second, the results of the request are transmitted from the host to the remote computer in a format that is preferably encoded and transparent to the remote user. Third, the results are remotely processed in response to user interaction with the results. The processed results are dynamically adjusted and displayed as the user interacts with the results. Graphical user interface control devices are used to allow user interaction and adjustment of the results. For example, slider filter controls, alphanumerical boxes, drop-down menus, or the like can be used. The system and method of the present invention preferably utilizes client side-processing of the results instead of server-side processing. This enables the user to quickly access and adjust information dynamically and in real time without server delays.

The foregoing and still further features and advantages of the present invention as well as a more complete understanding thereof will be made apparent from a study of the following detailed description of the invention in connection with the accompanying drawings and appended claims.

With reference to FIG. 1, an exemplary system for implementing the invention includes a general purpose computing device in the form of a conventional computer 100, including a processing unit 102, a system memory 104, and a system bus 106 that couples various system components including the system memory 104 to the processing unit 102. The system bus 106 may be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures. The system memory includes computer storage media in the form of read only memory (ROM) 110 and random access memory (RAM) 112. A basic input/output system 114 (BIOS), containing the basic routines that helps to transfer information between elements within computer 100, such as during start-up, is stored in ROM 110. The computer 100 may include a hard disk drive 116 for reading from and writing to a hard disk, not shown, a magnetic disk drive 118 for reading from or writing to a removable magnetic disk 120, and an optical disk drive 122 for reading from or writing to a removable optical disk 124 such as a CD ROM or other optical media. The hard disk drive 116, magnetic disk drive 128, and optical disk drive 122 are connected to the system bus 106 by a hard disk drive interface 126, a magnetic disk drive interface 128, and an optical drive interface 130, respectively. The drives and their associated computer-readable media provide storage of computer readable instructions, data structures, program modules and other data for the computer 100. Although the exemplary environment described herein employs a hard disk, a removable magnetic disk 120 and a removable optical disk 130, it should be appreciated by those skilled in the art that other types of computer readable media can store data that is accessible by a computer. Such computer readable media can be any available media that can be accessed by computer 100. By way of example, and not limitation, such computer readable media may comprise communication media and computer storage media. Communication media typically embodies computer readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set of changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as wired network or direct wired connection, and wireless media such as acoustic, RF, infrared and other wireless media.

Components and Operation

FIG. 2 is a block diagram illustrating an overview of the present invention. The present invention is embodied in a system for adjusting data values in real time in response to remote user interaction with the data values. The system includes a host unit or server 210 coupled to at least one remote unit or client 212. In response to an initial client query 214 by a user through a user interface (UI) 216, such as a graphical user interface (GUI), data 218 stored on the server 210 is accessed, preferably as sorted data, to produce results 220 comprised of data values. The results 220 are transmitted to the client 212 and displayed on the user interface 216. The user at the client 212 is provided with interactive options 222 related to the data values, which allows the user to interact with the data values and make adjustments to the data values with user input directed to the interactive options 222. A control module 224, which can be sent from the to server to the client or created on the fly on the client 212, is preferably located on the client 212 during user interaction with the data values. The control module 224 controls the transmitted results and processes the user input for providing dynamic adjustment of the data values and real time user interactivity.

FIG. 3 is a flow diagram illustrating the general operational flow of the present invention. Specifically, a host computer or server collects and processes data to produce results in response to a request for information from a remote computer or client (step 300). The results of the request are transmitted, preferably in an encoded format that is hidden from and transparent to the user, to the client from the server (step 310). The user is provided real time interactivity of the results with user input through interactive user interface options (step 312), such as graphical user interface tools. Adjustments of the results by the user are displayed on the user interface of the client in real time (step 314). The user input is preferably processed at the client to allow the real time interactivity in the form of adjustment, filtering and viewing of the results. FIGS. 2 and 3 refer to one server and one client for illustrative purposes only. It should be noted that the server referred to in FIGS. 2 and 3 can be one or more servers coupled to numerous respective clients and can communicate simultaneously with the clients in the manner described in FIGS. 2 and 3.

FIG. 4 is a block diagram illustrating a processing method in accordance with the present invention. In one embodiment, the present invention utilizes client-side processing. Client-side processing involves performing data adjustment in response to user input on the client instead of on the server. Client-side processing provides a remote user with real time interactivity and dynamic data adjustment, unlike server-side processing, which forces the remote user to access the server every time the remote user adjusts the data.

For example, as shown in FIG. 4, client₁ 400 makes request₁ (R₁), client₂ 410 makes request₂ (R₂) and client_x 412 makes request_x (R_x). A server 414 utilizes a gather request module 416 that gathers and sorts respective raw data results for each respective request. A gather data module 418 gathers, for example, respective encoded data, such as pre-compressed data packets that are associated with their respective raw data results. A transmit module 419 transmits the pre-compressed data packets, a control module (CM₁, CM₂, CM₃) for each pre-compressed data packet and a decompressor to respective clients (Client₁, Client₂, Client₃) in a format that is preferably transparent to respective users of the clients 400, 410, 412.

The transmitted control modules 420, 422, 424 reside on each client and decode and decompress the pre-compressed data to reproduce raw data results for each client. Each control module 420, 422, 424 also displays the respective raw data results for each respective client 400, 410, 412. In addition, each control module 420, 422, 424 provides each user with interactive options for adjusting the raw data results. For example, a graphical user interface control, such as graphical gauges, can be provided. The gauges can be a slider with, for example, dual upper and lower bounds or can be a single slider with a range bounded by zero and a fixed value. Since each control module resides on the client, they are able to process and display adjustments made by each user in real time, thereby providing a dynamic interactive environment.

The gather request module 416 and the gather data module 418 can utilize structured query language (SQL) techniques to process the request and gather the data. The control module can be any suitable module for controlling operations, such as an ActiveX control, Java applet, Perl applet, etc. Also, the control module can utilize any suitable data structure for organizing and adjusting the data in real time. For example, an array, stack and queue, linked list, decision tree, etc. can be used. In addition, the interactive options can be user friendly user interface devices, such as progressive boundary gauges, or progressive alphanumeric entry boxes for adjusting the raw data results.

Working Example

FIG. 5 is a flow diagram illustrating a working example of the system and method of the present invention. FIGS. 6 and 7 are sample user interfaces of the working example of FIG. 5 of the system and method of the present invention. As discussed above, any suitable control component and client-side processing technique can be used. FIG. 5 is for illustrative purpose only and shows a component object model (COM) control, such as an ActiveX control of a working example. The ActiveX control can be written in C++, Java, Visual Basic, or any suitable programming language. The control component allows user manipulation of the results with graphical user interface development tools.

Specifically, as shown in FIG. 5, first, the remote user requests information based on user defined criteria (box 500). For example, the user can request classified pricing information for used cars for sale based on make and model or for real estate for sale based on location, property type, etc. Next, the system ensures that the client has a processing plug-in control module, such as an ActiveX portability container, coupled to the client (box 510). If the client does not have the plug-in module, the plug-in control module is transmitted from the server and installed on the client.

Next, the server collects the requested information relating to the user's defined request that is stored on the server, such as used car information sorted by price, year, miles, etc. or real estate information sorted by location, price, type of home, etc. to produce results in response to the defined request from the client (box 512). The server can encode and compress the data associated with the results on the fly or have the associated data available as stored accessible raw results with corresponding pre-compressed data or pre-encoded data representing the results. The results are transmitted to the client preferably as encoded pre-compressed data and in a format that is transparent to the client user (box 514). The encoded data representing the results is decoded by the plug-in control module at the client to reproduce the raw results (box 516), which are displayed on the user interface 600, 700 of the client in a user readable format 610, 710 as shown in FIGS. 6 and 7, respectively. The results can be displayed as a query grid having at least one field and associated criteria.

Last, the client user is provided with real time interactivity of the results through interactive user interface options, such as graphical user interface tools (box 518). These interface options can include configurable slider filters, input boxes that can accept alphanumerical input or the like, drop-down menus or any suitable interface, such as graphical gauges that allow a user to move graphics within a reference datum for adjusting the criteria for associated fields in real time (box 518). For example, as shown in FIGS. 6 and 7, the user interface 600, 700 includes slider controls 620, 720 such as dual or single slider controls. The client user can click on a graphical lever and drag the lever of the slider filter control in either direction to narrow certain criteria of the results for each sorted field or category. For example, price, mileage, and year criteria for car sales, as shown in FIG. 6 or price range, property type, and age of home criteria for home sales for FIG. 7. The dual slider controls have multiple boundaries for constraining the results within a defined range, as shown in FIGS. 6 and 7.

Also, as shown in FIG. 7, the interface options can include configurable alphanumerical input boxes 730 and drop-down menus 740. The configurable alphanumerical input boxes 730 can be digitally coupled to the slider filters 720 so that both the slider filters 720 and the input boxes 730 dynamically change as the user configures the other interface. As a result, the user can interact with either interface option. In addition, the drop-down menus 740 and radio buttons (not shown) preferably have predefined criteria as the interface options. Since the plug-in control module resides on the client, interactivity by the client, for example with the use of the sliders, input boxes, drop-down menus, radio buttons or the like, is in real time. Therefore, as the user adjusts each of the sorted fields (car or home price, car mileage, car year, type of home, age of home, etc.) with the interface options, the data is filtered and displayed by the client dynamically.

The foregoing description of the invention has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many modifications and variations are possible in light of the above teaching.
