Definitions
- the present invention relates to methods and systems for enabling a user to map content of an electronic document so that the information can be accessed from an audio interface. More particularly, the present invention relates to methods and systems for enabling a user to identify and map regions of electronic documents containing text and links so that an audio representation of text located within selected regions and links can be easily accessed over a telephone system.
- portable telephones e.g. cellular and digital telephones
- portable telephones were not widely used because of problems that included providing coverage beyond major metropolitan areas, the expense of purchasing a portable telephone device, the expense of airtime for use, and for some people, because portable telephone devices were originally too big to make them convenient.
- portable telephones were mostly used only for vital business concerns rather than for personal matters.
- portable telephones have become increasingly more sophisticated, compact, and affordable.
- portable telephone use has dramatically increased, and for many people, it is now a primary means of communication.
- One area that may be particularly well-served by telephone access to the Internet is the personal home page market, as it is becoming increasingly popular for content providers, such as Yahoo!, to offer personal Web home pages that enable a user to compile various desired content into one location.
- content providers such as Yahoo!
- personal Web home pages that enable a user to compile various desired content into one location.
- a user may chose to have current data regarding various financial markets, weather, sports stories, headlines, technology, calendaring, contacts, entertainment, travel, reference, etc., appear on a single personal home page.
- these personal home pages are highly attractive because, after requiring an initial investment of set up time, they cut down the total amount of time a user would otherwise have to spend to find desired information on a reoccurring basis.
- a convenient way to access the Internet by telephone would be useful for anyone who does not have constant access to a networked personal computer. It would also be particularly beneficial to provide an effective audio interface to the Internet for enabling the visually impaired to access the Internet from a portable telephone device that does not have to be attached to Braille machinery.
- techniques have been developed that enable a user to access audio representations of Internet content. This is accomplished in one of two general ways, as illustrated in Figures 1 and 2. Either a Web page is modified to enable direct audio access from that page, or alternatively, text-to-speech software is used to dictate information from a static translation of an existing Web page.
- FIGS 1 and 2 show the two general prior art approaches for accessing the Internet with an audio interface.
- the first approach designated as 100, in Figure 1, illustrates a source 110 of electronic content that is accessible through telephone 120.
- the content in source 110 is written in a markup language specifically designed for enabling audio output through an audio interface.
- VXML Voice extensible Markup Language
- VXML Voice extensible Markup Language
- Requiring explicit voice elements presents a serious drawback, namely, it does not provide a means for accessing content that does not include VXML voice elements.
- NoxML fails to provide access to the wealth of content already available on the Web, written mostly in HyperText Markup Language ("HTML").
- HTML HyperText Markup Language
- the entire content of the Web would need to be rewritten to include explicit voice tags of a VXML.
- the difficulty of accomplishing this task is further compounded by the fact that because there are several existing VXMLs, and more potentially to be developed, it is unclear which VXML should be used or will ultimately be adopted by the industry.
- FIG. 2 shows another prior art approach, designated as 200, for enabling a user to access the Internet using an audio interface.
- HTML source 210 represents existing Web content that can be accessed through visual and audio interfaces.
- visual browser 220 provides a visual interface for monitor 230.
- static translation 240 provides an audio interface for telephone 250.
- Static translation 240 is a copy of at least a portion of HTML source 210 that has been manually altered to include audio elements.
- Someone examines HTML source 210 creates a corresponding audio interface using Text To Speech (TTS) technology, and then stores the audio interface in static translation 240.
- TTS Text To Speech
- Another problem for users of each of the foregoing techniques is that an Internet document provider can load the static translation 240, or the VXML source 110 with commercial advertisements that will ultimately be passed on to the user in audio form.
- This is a problem, not only because a user may find the advertisements to be obnoxious, but also because they can take up precious and sometimes expensive airtime associated with a portable telephone service agreement. Advertisements that are displayed on a graphical browser can be quickly viewed and dismissed, perhaps even unconsciously. However, audio representations of the same advertisements are presented in a time intensive sequential format that cannot be dismissed. This problem, however, is not limited to advertisements.
- the present invention is directed to methods and systems for enabling a user to control how information is presented to the user through an audio interface.
- One advantage of the present invention is that it allows for user-controlled access to existing Internet, Intranet, and other electronic documents without requiring any modification to the content source of the electronic documents.
- the present invention allows for a user to control what portions of an electronic document will be accessed from a customized hierarchal structure. It should be appreciated that although certain embodiments of the present invention are described as applying to Internet documents and Web pages in an Internet environment, the invention is not limited to any particular format of electronic information or any particular type of network for accessing electronic content.
- the methods and systems of the present invention can also be used to map Intranet documents, as well as files stored on personal computers.
- the information that is mapped from the electronic documents can be accessed with any telephone system, not only cellular or wireless telephones.
- a user creates a user-defined map from a user interface of a computer system that parses and displays Internet documents for mapping.
- the user selects a region of an Internet document to be mapped and designates whether the selected region corresponds to links or text of the selected region.
- the user also assigns a name to the designated links or text of the selected region.
- the present invention allows multiple Internet documents and regions to be mapped within a single user-defined map. It is also possible for a user to nest links and text in a hierarchal order, such that one region is mapped from the link of another mapped region.
- a user accesses a voice browser over a telephone to listen to an audio representation of mapped regions of an Internet document based on the user-defined map. Prompts and global commands facilitate a user's navigation through the hierarchy of the user-defined map.
- an audio representation of the selected text or links of the Internet document is transmitted over the telephone to the user. If content of a mapped region is modified subsequent to mapping of the region, the updated content of the region is presented to the user.
- the invention generally enables a user to control how content of an Internet document is presented to the user through an audio interface, according to a hierarchy that is defined by the user, without requiring any modification to existing content of the Internet document, but accommodating for it.
- One benefit of the invention is that it can significantly minimize the time that is required for a user to access content from the Web by enabling a user to eliminate undesired content from the sequential transmission of audio data that is transmitted to the user through an audio interface. Minimizing the time it takes to access content from the Web is also economically beneficial when access to the Web is achieved using a cellular or digital phone with accompanying airtime costs.
- the invention is also beneficial to users for enabling users to forgo listening to commercials and advertisements from the audio content that is received.
- the invention is also beneficial for facilitating navigation of the Web over a telephone, by enabling a user to control how content is categorized so that the user can know exactly where to access the information that is desired.

- Figure 10B is an example of modified electronic content of the Internet document of Figure 10A that corresponds to the region of a user-defined map of Figure 10A.
- the present invention is directed to methods and systems for enabling a user to define how an audio representation of electronic content is presented to the user through an audio interface.
- the present invention enables a user to control what portions of an electronic document will be presented to the user over a telephone system. More particularly, the present invention enables a user to create a user-defined map that includes a customized hierarchy of categories and mapped regions corresponding to Internet documents that can be retrieved by the user over a telephone to access Internet content corresponding to the user-defined map.
- the invention enables a user to create a user- defined map from a user interface of a computer system that parses and displays Internet documents for mapping.
- the user selects and names a region of an Internet document to be mapped and designates whether the selected region corresponds to links or text of the selected region.
- Multiple Internet documents and regions can be mapped within a single user-defined map. It is also possible for a user-defined map to include mapped regions that are nested, such that one region is mapped from the link of another mapped region.
- a user accesses an audio representation of mapped regions of an Internet document based on the user-defined map with a voice browser over a telephone system. Prompts and global commands facilitate navigation through the user-defined map.
- an audio representation of the selected text or links is transmitted over the telephone to the user. If content of a mapped region is modified after the region is mapped, the modified content is identified and presented to the user.
- One particular benefit of the embodiment just described is that it enables a user to control how content of an Internet document is presented to the user over an audio interface without requiring modification to the Internet document, but while accommodating for it. It should be appreciated, however, that the invention is not limited to mapping and accessing Internet documents. In particular, the methods and systems of the present invention can also be used to map and access Intranet documents, files stored on personal computers, and cached copies of files stored in storage medium.
- Embodiments of the invention may comprise a special purpose or general-purpose computer comprising various computer hardware. Embodiments may also include computer-readable media having computer- executable instructions or data structures stored thereon. Such computer-readable media can be any available media that can be accessed by a general-purpose or special-purpose computer. By way of example, and not limitation, such computer- readable media can comprise RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired executable instructions or data structures and which can be accessed by a general-purpose or special-purpose computer.
- Computer-executable instructions comprise, for example, instructions and data which cause a general- purpose computer, special-purpose computer, or special-purpose processing device to perform a certain function or group of functions.
- the computer-executable instructions and associated data structures represent an example of program code means for executing the steps of the invention disclosed herein.
- program modules include routines, programs, objects, components, data structures, or the like that perform particular tasks or implement particular abstract data types.
- program modules may be practiced with other computer system configurations, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, network PCs, minicomputers, mainframe computers, and the like.
- the invention may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network.
- program modules may be located in both local and remote memory storage devices. Turning now to Figure 3, one suitable environment 300 for practicing the invention is illustrated.
- a server system 310 is connected to the Internet 320, a computer system 330, and a telephone system 340.
- the Internet is shown to include Internet documents 350, which should generally be construed to include any Internet document comprising electronic content.
- Internet documents 350 should generally be construed to include any Internet document comprising electronic content.
- HTML source document as one example of electronic content that is common to the Internet.
- the invention can be practiced with Internet documents comprising other types of electronic content.
- other types of electronic content include documents encoded in extensible Markup Language (XML) and Voice extensible Markup Language (VXML).
- XML extensible Markup Language
- VXML Voice extensible Markup Language
- the invention is not limited in its application to documents located on the Internet, but can generally be practiced on most types of network data and content that can be accessed from a browser.
- graphical browser 350 comprises a user interface that performs the acts that enable a user to map Internet documents 350 according to the invention. It should be appreciated that graphical browser 350 can be operated in connection with a common visual browser, such as Microsoft's Internet Explorer and Netscape's Navigator, which are both well known in the art. According to the current embodiment, graphical browser 350 initially retrieves or receives Internet documents 350 according to user input. Then, according to user input, graphical browser 350 maps selected regions from the Internet documents 350 to create a user-defined map and subsequently transmits the user-defined map to database 360 of the server system 310. Although database 360 is shown and described as being included within server system 310, it should be appreciated that the database 360 can also be located at a remote location.
- graphical browser 350 comprises a user interface that operates only as a proxy for enabling a user to map Internet documents 350 with mapping module 370. According to this embodiment, all acts that are required for creating a user-defined map are performed at server system 310 by mapping module 370 upon receiving the required user input from graphical browser 350.
- Figure 4 shows some of the basic components that make up mapping module 370.
- Document retrieval protocols 410 request and retrieve electronic content that is displayed on the user interface.
- Document retrieval protocols 410 are well known in the art of accessing electronic content, especially in the context of Internet documents.
- document retrieval protocols 410 preferably access and retrieve a cached copy of the file from an Intranet database. This is preferred over accessing the file directly from a computer harddrive because the computer may be periodically turned off, whereas the Intranet database can be accessed at almost any time.
- Document parsing 420 receives electronic content and identifies any text and links included within the electronic content and is an example of processor means for parsing electronic documents.
- Links are content elements that lead to other locations in the same document or to other documents entirely.
- HTML links for example, create locations within a document's visual representation that may be selected to further explore the link's subject, such a defining a word or leading to related material.
- Prompt & command recognition 430 performs the acts that are necessary to communicate with a user and to receive user input that defines how electronic content of an Internet document is to be mapped.
- mapping module can present to a user, such as "What is the address (URL) of the site you want to map?”, "Please enter a name for this bookmark", and "Do you want to add text or links from this page?”
- prompts which can be displayed on the user interface according to the invention, will be discussed more thoroughly in reference to Figure 7.
- Command processing & mapping 440 compiles user input to generate a user- defined map and transmits the user-defined map to a database.
- Command processing & mapping 440 may also perform various general control functions and coordinate the operation of other components.
- components 410-440 are described as generally pertaining to mapping module 370, that they may also be incorporated within graphical browser 350 for enabling graphical browser 350 to perform the acts of the invention that are necessary for enabling a user to create a user-defined map of electronic content.
- server system 310 also includes voice browser 380.
- voice browser 380 provides an audio interface for a user to receive audio representations of electronic content contained within regions of Internet documents 350 that correspond to a user-defined map.
- Voice browser 380 can also operate independently of a user-defined map. It may, for instance, provide audio content from the Web according to automatic mapping systems and methods that are described in U.S. Patent Application Serial No. 09/464,989, entitled “Voice Interface for Electronic Documents," filed December 16, 1999, which is incorporated herein by reference.
- voice browser 340 can be used in conjunction with a visual browser to provide simultaneous visual and audio output to users accessing the Web.
- voice browser 380 is accessed by a user through telephone system 340, which is generally defined herein to include any cellular telephone, digital telephone, landline telephone, computer or electronic device having telephone capabilities, and any other type of telephone device that currently exists or that may be developed, and that is capable of interfacing with voice browser 380.
- Figure 5 shows some of the basic components that make up voice browser 380.
- Line/call manager 510 is responsible for establishing and maintaining telephone connections. Modules for implementing line/call manager 510 are well known in the respective art.
- Speech recognition 520 interprets audio or voice data received from user input. Speech recognition 520 can also interpret user input comprising telephone signals, such as Dual Tone Multi-Frequency (DTMF) signals.
- DTMF Dual Tone Multi-Frequency
- Speech recognition 520 is an example of processor means for receiving a command from a user. Modules for implementing speech recognition 520 are well known in the respective art.
- Command processing 530 executes user requests, performs various general control functions, and coordinates the operation of other components.
- Document retrieval protocols 540 request and receive electronic content of interest and are examples of processor means for obtaining electronic documents and for following links. Document retrieval protocols 540 are well known in the art of accessing electronic content, especially in the context of HTML documents.
- Document parsing and audio layout 540 receives electronic content and identifies any text and links included within the electronic content and is one example of processor means for parsing electronic documents.
- Document parsing and audio layout 540 can also be used to retrieve a user-defined map 560 and to compare it with an Internet document to determine what text and links of the Internet document are included within the mapped region of the user-defined map. This can also be accomplished by the components of mapping module 370, which are shown and described in reference to Figure 4. If voice browser 380 is used independent of the user-defined map 560 of the invention, the audio layout portion of 540 organizes certain content of Internet documents into a hierarchy, as an aid to navigation, and is one example of processor means for mapping any text and links identified into one or more categories.
- Text to speech module 570 converts text from Internet documents into speech that is transmitted to the user over a telephone system and is an example of processor means for generating an audio representation of electronic content. Text to speech 570 may also include some prerecorded audio content including, for example, frequently used words, links, text, and prompts. Modules for implementing text to speech 570 are well known in the respective arts.
- One method of the invention for enabling a user to create a user-defined map of an Internet document, or any other type of electronic document, can be accomplished by performing the acts shown in the flow chart of Figure 6 and will be generally described in reference to Figures 6-7.
- Internet document can occur prior to or subsequent to the act of parsing the document.
- a particular document is requested and received.
- document retrieval protocols 410 may prompt the user to select or request a desired source of information. Once a requested document is received, it can be displayed on display 700 of the user interface.
- the prompt "Please enter the address (URL) of the site you want to map” is entered in prompt field 710.
- a user enters commands and responses to any prompts in response field 720. As shown, a response "www.yahoo.com” has been entered within response field 720.
- Buttons, such as go button 730 can assist a user in entering responses.
- Various buttons may be used to assist the user, including Help, Back, Forward, Yes, No, and Exit buttons. Each of these buttons and their corresponding uses are well recognized in the computer industry.
- requested document 740 includes information in various categories, which is typical of personal Web homepages.
- the categories of requested document 740 include portfolio category 750, weather category 760, and my front page Headlines category 770.
- document parsing 420 parses the content, step 620, to identify any title, any text, any links, and any link names included within the document.
- a link name is simply the text that forms the link. For example, "weather" 761 is the link name of weather category 760. According to another embodiment, however, document parsing does not occur until the requested document 740 is retrieved and compared to a user-defined map, as described in step 950, of Figure 9.
- Figure 7 illustrates how requested document 740 may look after it is parsed. As shown, some portions of the requested document 740 are filtered out and ignored. Top banner 780 and bottom banner 790 include a variety of images that are not particularly suitable for voice interaction. Each of the category areas 750-770 may also include content that is ignored and is not displayed, such as graphics. Other unsuitable content that is ignored includes JavaScript, flash objects, and video. If a Web page only contains these type of images then the Web page is not be displayed, but instead an error message of some type is presented to the user.
- step 630 Once the requested document 740 is parsed, certain text and links included within the document are mapped, step 630.
- the prompt field 710 is replaced with the prompt "Is there any information here you would like to map?”
- the user responds by entering "Yes” in the response field 720, or by selecting a Yes button, if one is provided.
- the prompt field 710 is then replaced with the prompt "Do you want to add text or links from this page?"
- the user responds by entering either "Text” or “Links” in the response field 720, or by selecting an appropriate button.
- the user is then prompted to "Select an area of text by clicking and dragging your mouse over the selected text," or to "Select a link or group of links by clicking and dragging your mouse over the group.”
- a selected region of the requested document 740 is selected, and associated with either text or links, the user is prompted to "Enter a name for this voicelink.”
- a user can then name the selected region according to personal preferences, which organizes the associated links or text for easy access.
- the set of prompts may be presented again, and may repeat until the user stops the mapping process.
- the user can also be presented with options that enable the user to map Web pages that are linked from the requested document 740. For example, when the user is prompted "Do you want to add text or links from this page?,” the user may enter or select "No,” in which case the user is presented with the prompt "Using the screen on the right follow the link to the page you want to map.” The user can then use standard Internet navigation to find a linked page by selecting any of the links that are displayed. The user can then map the linked page according to the process just described. It should be appreciated that this enables a user to organize a hierarchy of nested links that depend from one another.
- a user responds to the prompt "Is there any information here you would like to map?” by entering “Yes.”
- the next prompt "Do you want to add text or links from this page?” the user enters "Links" and subsequently selects region 772 of news category 770, which is highlighted.
- the user enters the name "News" in response field 720. The user then proceeds to map region 752 of category portfolios. 750, which is highlighted.
- This region is mapped for text according to user input, and correspondingly named "Portfolios.”
- the user maps region 762 of weather category 760 and names the selected region "Weather.” The user then terminates the mapping process by entering a command or by selecting an appropriate button.
- FIG. 8 A visual representation of the user-defined map 800 that was created from the example just given is shown in Figure 8.
- the user-defined map 800 contains a hierarchy that includes a menu of categories 810.
- the next level, corresponding to the menu of categories 810 includes news 820, portfolios 830, and weather 840.
- Each of these includes text 850, 860 and links 870 that correspond to the regions that were mapped by the user.
- the text 850, 860 and links 870 of the categories 820-840 do not include text and links of the requested document 740 that are not located within the mapped regions 752, 762, 772. This is useful because it enables users to selectively omit content from Web pages that they do not want to receive in audio form through an audio interface. This is particularly beneficial when mapping a Web page other than a personal homepage that can be customized by a user to contain only desired content.
- the user did not nest or map a Web page that is linked to the requested document 740. It should be appreciated, however, that this is possible, as indicated by step 640. If a user does choose to map a linked Web page to the existing user-defined map 800, then user- defined map 800 would include at least one more level of in its hierarchy. It is also possible for multiple Internet documents to be mapped into a single user-defined map. Multiple documents can be organized by bookmarks or with categories of a user- defined map. Once the user-defined map is generated, according to step 630 it is stored in database 360 of server system 310 were it can be retrieved and referenced or updated at any time.
- mapping process does require an initial investment of time, it enables a user to quickly access content from the requested document 740 through a user interface on a reoccurring basis, saving overall time. This becomes even more apparent by the following discussion related to how a user accesses content associated with a user-defined map.
- voice browser 380 enables a user to access the Internet 320 from telephone device 340.
- One method of the invention for providing a user with controlled access to the Internet 320 is illustrated by the steps or acts in Figure 9.
- the first step 910 is to retrieve the user-defined map, which is accomplished in response to user input, commands or requests that are received by voice browser 380.
- User input or requests can include spoken words and signals that are generated by pressing keys on a keypad.
- user input includes key words that are spoken, such as "Internet,” or "Connect me to the Internet.”
- a user can also be assisted with prompts.
- speech recognition 540 interprets the command so that it can be processed.
- Voice browser 380 next presents the user with an audio representation of the mapped regions of the Interned document based on the user-defined map in a chronological and hierarchal order according to the structure of the user-defined map. This is accomplished, for example, by prompting the user to select a category, step 920.
- voice browser 380 may present the user with the following audio content: "News" (pause) "Portfolios” (pause) "Weather”.
- Voice browser 380 can also assist the user by providing a prompt such as "Please select one of the following" The user enters a selection by either speaking the selection or entering appropriate keys of the key pad as prompted.
- step 930 if the selected category contains sub-categories, then user is also presented with a prompt to select a sub- category.
- a user can be presented with prompts related to bookmarks or favorites, of which categories may be a subset, or of which categories may be included.
- the act of prompting a user for a category name, step 920, and the act of prompting a user for links or sub-categories, step 940 can also be practiced in connection with Provisional U.S. Patent Application Serial No. 60/263,003, entitled "Dynamic Super Menu and Whisper Coach," filed January 19, 2001, in which dynamic menuing is generated on the fly.
- the Internet document corresponding to the information that was selected is retrieved, step 940, and compared to the user-defined map, step 950. This is necessary to determine what content from the Internet document will be transmitted to the user.
- document parsing 420 parses the Internet document to identify any text and any links included in the Internet document.
- a user in communication with Voice Browser 380 selects "Weather" as the category from prompts that are presented to the user over the telephone.
- Document retrieval protocols 560 retrieves the requested document 740 and subsequently compares the user-defined map 800 to the requested document 740 to determine what content will be transmitted back to the user. If the content corresponding to the "Weather" is the same as the content that was originally mapped in region 762, then the user will receive an audio representation of the exact text that was mapped, step 970.
- An audio representation of the content that corresponds to mapped region 762 is generated by text to speech 520, and is subsequently played or transmitted to the user, step 970. In the present example, the user hears an audio representation of "Salt Lake City, UT 49...82F.”
- the updated content of the mapped region is transmitted to the user.
- the following example is given as a matter of illustration, and not limitation, to show how the invention accommodates modification of content in the mapped region of a Web document.
- the news stories have changed since they were first mapped. It is common for news stories and headlines to change daily.
- a user selects "News" over telephone 340.
- Document retrieval protocols 560 retrieves the requested document 740 and compares it to mapped region 772 of news category 820.
- Figure 10A illustrates mapped region 1072 and corresponding links 1074, as originally mapped.
- Figure 10B shows mapped region 1072A and associated links 1074A that correspond to the new news and an updated version of requested document 740, not shown.
- the updated region 1072A is spatially larger than the original mapped region 1072.
- Algorithms can be used to enable document retrieval protocols 560 to determine where a mapped region begins and ends so that the mapped region can expand or shrink to accommodate modifications to content of an Internet document. Otherwise, if a mapped region were limited to spatial constraints during mapping, then desired content could be bumped out of a mapped region or undesired content might be added to a region whenever a Web page is modified.
- the present invention uses pointers, matching systems and algorithms to determine where the beginning and ending of a mapped region is.
- one suitable algorithm comprises the Diff algorithm, or the UNIX Diff algorithm.
- the invention enables a mapped region to expand or shrink while preserving the integrity of what is mapped between the start and end of the regional boundaries, or tags. This is particularly useful when mapping a cached copy of a file from a personal computer or an Intranet document.
- the cached copy of the file that is mapped can be updated by a mirroring process, when backing up the files of the computer or Intranet system, while preserving the integrity of the user-defined map of the cached copy. This generally enables a user to get what is desired and only what is desired from a mapped document, even when the document undergoes changes.
- this feature of the invention also extends the life of a user-defined map, so that it does not have to be updated every time a mapped Web page or electronic document is modified. Periodically, however, a user may be required to update the user-defined map if wholesale changes are made to the mapped document that cannot be accommodated for.
- voice browser 380 If voice browser 380 is unable to perform the acts as defined for any reason, such as when selected regions or Web documents associated with a user-defined map become obsolete, then voice browser 380 can default to an automatic system of parsing and mapping Internet documents to enable the user to navigate the Web according to the methods and systems described in U.S. Patent Application Serial No. 09/464,989, entitled “Voice Interface for Electronic Documents,” filed December 16, 1999.
- the user is presented with an audio representation of the links 1074A contained in the updated region 1072A. Because region 1072A comprises links 1074 A, the user is also prompted to select one of the links 1074A. Upon selecting one of the links 1074 A, the text of the Web page associated with the selected link is read to the user. At any time a user can navigate back and forth between the different hierarchal levels of the user-defined map 800 by entering appropriate commands.
- step 950 when the user-defined map is compared to the retrieved Internet document, the act of parsing the retrieved Internet document may also be performed to facilitate the performance of step 950.
- the invention as it has been described herein, generally enables a user to control how content of an Internet document is presented to the user through an audio interface, according to a hierarchy that is defined by the user, without requiring any modification to existing content of Internet document, but while accommodating for it.
- the invention also enables a user to access mapped regions of an Internet document according to a user-defined map, even when content within the region is modified after being mapped by the user. It should be appreciated that these benefits of the invention are advantages over the prior art.
- the invention can significantly minimize the time that is currently required for a user access content from the Internet, Intranet, or personal computer by enabling a user to eliminate undesired content from the transmission of audio data that is transmitted to the user.
- the invention also provides a user with more control over how and what content is accessed from the Internet, Intranet, or personal computer through an audio interface by enabling a user to control how content is mapped.
- the invention also enables a user to know exactly where to access the information that is desired so that it can be accessed in a quick and convenient manner.
