Abstract:
A technique to generate a web-based presentation is described that includes obtaining an entry from a feature table (the entry having an identification portion and an installation portion), and generating at least part of the presentation based on the installation portion if the entry corresponds to a loaded feature. At least a part of the presentation may also be generated based on entries not associated with operational features of a computer system. The method may be automatically executed on initial system power-up, or on user command.

Description:
This application is related to U.S. patent application Ser. No. 09/201,330, entitled “System Tour Generator,” filed on Nov. 30, 1998. 
    
    
     BACKGROUND 
     The invention relates generally to human-computer interfaces, and more particularly to a self-generating on-line computer based help and tutorial system. 
     It is becoming common for purchasers (consumer and industrial) of computer systems to custom order their machine directly from the manufacturer (e.g., an original equipment manufacturer, OEM). In addition to specifying the central processing unit, amount of system random access memory, and one or more types of long-term storage (e.g., magnetic and optical disk units), purchasers may also request their system come configured to provide certain features. Illustrative features include telephony, a backup subsystem, and digital video disk capability. 
     Systems are typically shipped to the purchaser with the requested features&#39; associated software preloaded and ready to run. To assist the user, many software applications provide on-line help systems and user manuals. While on-line help systems and manuals may assist users in determining how to use a specific application or feature, they are often underused because they are perceived as difficult to understand, especially to new users. In addition, on-line help systems and manuals do not provide the user with an overall introduction to their computer system, taking instead on a feature-by-feature approach. 
     Failure to provide users with an overall or system&#39;s level introduction may lead to misuse, nonuse, calls to a vendor&#39;s technical support department, or feelings of dissatisfaction of the very features the user requested. This may be a particularly important issue for users of a new computer system. Thus, there is a continuing and significant need to provide users with an automated and easy to use system&#39;s level introduction to their new computer system. 
     SUMMARY 
     In one embodiment the invention provides a program storage device having stored thereon instructions to implement a method in accordance with the invention. The program storage device may comprise any media that is readable by a computer system. The instructions may be any format that may be interpreted by a computer system. For example, the instructions may conform to the C programming language or assembly language.

     DETAILED DESCRIPTION 
     Techniques (including methods and devices) to provide automated and easy to use tutorial and on-line help information to computer system users are described. The following embodiments of this inventive concept are illustrative only and are not to be considered limiting in any respect. 
     The growing popularity of web-based presentations (presentations that utilize hypertext links and/or the internet), and the ability to automatically and dynamically incorporate hypertext links in a web-browser or browser-like environment, makes it possible to provide tutorial and on-line help information in a manner that may be more readily understood, useful, interesting, and beneficial to a user than prior techniques. 
     In accordance with one embodiment of the invention, a System Tour Generator (STG) may create and display a web-based presentation or system tour for a new user in accordance with FIG.  1 . The system tour may include a document (a main page  100 ) containing text  102 , graphics  104 , and hypertext links (hereinafter links) to sub-tours (that is, information about one or more of the features available to the user on their particular system such as a system setup management sub-tour link  106  and a telephony feature sub-tour link  108 ). One or more links may to sales and technical contact information  110  may also be provided. In another embodiment of the invention, a STG may create and display a web-based presentation of more advanced information. For example, sub-tours dealing with advanced attributes and technical data may be provided. 
     Sub-tours may be created for each feature of the computer system. In general, a feature may be any device, software or combination thereof which adds value to a computer system, the use of which may be enhanced by providing instructions to the end user. Illustrative features include telephony (e.g., a modem with telephone, messaging and speaker phone capability), a magnetic tape backup subsystem, digital video disk (DVD) and removable mass storage device capabilities. Each sub-tour may contain information specific to the associated feature such as getting started instructions, set-up tips and tricks, frequently asked questions (FAQs), links to manufacturer web sites and links to third party sites providing support (e.g., third party technical support, discussion groups relating to the feature and sites providing products and services associated with the feature). 
     Referring to FIG. 2, a method in accordance with one embodiment of the invention to create a system tour is shown. On system power-up (block  200 ) an STG may obtain the first entry of a feature table (block  202 ). In one embodiment, the feature table provides the STG application with the logic needed to create a main page. 
     Referring now to FIG. 3, each feature table entry  300  may include an identification field  302 , a detection field  304  and an installation field  306 . Identification field  302  may identify the entry as a feature entry or a header entry. Feature entries are associated with features (e.g., telephony) and may be used by the STG to create sub-tours (see discussion below). Header entries may be used by the STG to place information on the system tour&#39;s main page without regard to an associated feature. Header type information may include manufacturer identification (e.g., a graphical link to the manufacturer&#39;s main and/or technical assist web site) and advertisements. Detection field  304  informs the STG how to determine if the identified feature has been installed. (Header entries may have a null detection field.) For example, many features may be associated with one or more registry keys (in a windows based operating system), one or more application programs or one or more dynamic link libraries (DLLs)—detection field  304  may identify one or more of these entities. Installation field  306  indicates how the STG is to place the (header or feature/sub-tour) information on the system tour&#39;s main page. For example, installation field  306  may include hypertext markup language (HTML) instructions that are inserted into the system tour&#39;s main page document. In another embodiment, installation field  306  may indicate a file that is to be inserted into the system tour&#39;s main page document. In yet another embodiment, installation field  306  may include a script program that the STG executes (or has executed by another program) to include the relevant information in the system tour&#39;s main page. In another embodiment, the feature table does not have to have a detection field. Instead, the STG could take a default action wherein the it looks for windows registry entries associated with the feature indicated in the identification field. 
     Returning again to FIG. 2, if the entry is a header type entry (the ‘yes’ prong of diamond  204 ), the entry&#39;s installation field may be used to update the system tour&#39;s main page (block  206 ) and processing continues at block  214 . If the entry is a feature type entry (the ‘no’ prong of diamond  204 ), the entry&#39;s detection field is used to determine if the feature has been installed (block  208 ). If the feature has been installed (the ‘yes’ prong of diamond  210 ), the entry&#39;s installation field is used to update the system tour&#39;s main page to reflect the feature&#39;s sub-tour (block  212 ). Following block  212 , or in the event the feature associated with the current entry is not installed (the ‘no’ prong of diamond  210 ), the STG determines if all entries in the feature table have been processed. If all feature table entries have been processed (the ‘yes’ prong of diamond  214 ), the resulting system tour is displayed (block  216 ), and STG processing terminates (block  218 ). If all feature table entries have not been processed (the ‘no’ prong of diamond  214 ), processing continues with the next feature table entry (block  202 ). 
     In one embodiment, a feature table entry may be processed (block  212 ) by inserting on the system tour&#39;s main page textual and graphical information relating to the feature. In addition, links to collateral information stored either on a storage unit coupled to the computer system (e.g., a magnetic or optical CD ROM disk) or at a distant site (e.g., a manufacturer&#39;s web site) may be inserted into the system tour&#39;s main page. In general, links may be textual or graphical in nature and may invoke presentation of additional information—text, and/or graphs, and/or audio and/or video in nature. For example, processing a feature entry (in accordance with the entry&#39;s installation field) may result in a link (e.g., a replica of the feature&#39;s graphical trademark) to the feature&#39;s manufacturer being placed on the main page. Introductory information of the type discussed above may be provided may also be provided on the main page. 
     In another embodiment, the feature table and all related sub-tour data is stored in a specified location on a computer system&#39;s long-term storage unit. During execution, the STG may create a system tour directory and place the main page (and associated files such as graphics and audio files) in the system tour directory. Following creation of the system tour&#39;s main page, the STG may delete the original feature table and all sub-tour modules associated with features not installed. In this manner, the user has access to the system tour whenever she/he wants, but the memory associated with non-installed features has been reclaimed for use. 
     In one embodiment the system tour may be generated the first time the end user (e.g., purchaser) powers-up their computer system. In a windows environment, this feature may be provided by associating the window&#39;s registry key “RunOnce” to the STG. In another embodiment, the system tour may be generated on user command. 
     Referring to FIG. 4, a computer system  400  for providing system tour capability in accordance with one embodiment of the invention is shown. Computer system  400  includes processor  402  coupled to primary bus  404  through bridge circuit  406 . Processor  402  may be a general purpose processor such as a microprocessor, or a special purpose processor such as a digital signal processor or microcontroller. Bridge circuit  406  typically provides an interface to system random access memory (RAM)  408 . During execution, a copy of STG program  410  may reside in RAM  408 . In addition, STG  410  typically creates the system tour&#39;s main page  412  in RAM  408 . 
     Bridge circuit  414  may couple primary bus  404  to secondary bus  416 , while also providing interfaces to integrated device electronics (IDE) devices such as storage device  418 . At system assembly time, a copy of STG program  420 , feature table  422 , and tour data  424  (e.g., information associated with feature table entries) may be loaded on storage device  418 . During STG execution, processor  402  may copy STG program  420  into RAM  408  to create STG execution copy  410 . Illustrative storage devices (e.g.,  418 ) include long-term storage devices such as magnetic hard disks (fixed, floppy, and removable), magnetic tape, optical disk units, and all forms of electronic non-volatile memory (e.g., programmable read only memories). 
     Secondary bus  416  may also couple input-output (I/O) circuit  426 , keyboard controller (KYBD)  428 , and system read only memory (ROM)  430  may also be coupled to system  400 . Input-output circuit  426  may provide an interface for parallel  432  and serial  434  ports, floppy disks  436 , and infrared devices  438 . 
     One benefit to providing a user with system information in a web-based environment as described above, is that a manufacturer may gradually develop a series of sub-tour modules. As each sub-tour is created (either by the system manufacturer or the feature manufacturer), an entry for that sub-tour may be placed in the feature table. Because only those entries associated with features actually installed are processed by the STG (see block  212  of FIG.  2 ), the same feature table may be stored on a large number of computer system storage devices during the manufacturing process. Another benefit to the presentation of information as described above, is that it may provide a new user with all the information, including links to additional support centers, in a easy to understand and use manner. 
     While the invention has been disclosed with respect to a limited number of embodiments, numerous modifications and variations will be appreciated by those skilled in the art. It is intended, therefore, that the following claims cover all such modifications and variations that may fall within the true sprit and scope of the invention.
