Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates generally to document browsing. 
       BACKGROUND OF THE INVENTION 
       [0002]    Document browsing such as web browsing constitutes a major portion of Internet usage by individuals and user experience with browsers is the basic metric in the choice of web browsers. Over the past decade, a number of web browsers such as Microsoft Internet Explorer, Firefox, Netscape, AOL Explorer etc. emerged with oft-times intense competition for the user audience. Many outstanding features have surfaced, including toolbars, plug-ins, shortcut maintenance and even built-in editing and composing. Most recently, tabbed menus were introduced for maintaining simultaneous contexts. Despite those improvements, the user has not been adequately supported from a time/motion vantage point. For example, a major flaw is the requirement for the most common repetitive motion circumstance: the browsing of adjacent hyperlinks in a web page. The user “clicks” a hyperlink to follow a news article in a list area containing multiple news articles. It is necessary to use the back button before progressing to other articles in the list. Furthermore, if the list is generated from web directory browsing, there is no provision to automatically setup a “screen show” mode to allow the user to casually inspect items, such as pictures without laborious interaction. 
         [0003]      FIG. 1  shows prior art web browser displayed page. In a typical web browser system  101 , a user interacts with a dash panel  103  to specify navigations, specified as Uniform Resource Locators (URLs) to selected web sites. The process of navigation instructs the facility of the web browser to load a target URL in the manner conventional in the art. The invention is not limited to the specific protocol or versions of protocols to accomplish this. The typical target page is displayed in the main frame of the browser  104 . Certain navigation enablement is allowed for example, for navigating to prior pages  102  and previously visited (in the forward direction)  103  pages. Logically, these navigation means can be disabled for use until circumstances permit the “Back” or “Forward” navigation buttons. As is typical of web pages there can be areas wherein clicking can instigate a navigation to a URL. Common text and graphic locations of this nature are called hyperlinks  105 . The invention is not limited to the placement or physical proximity of hyperlinks listed or embedded in a Web page. It is expected that the user recognizes a list of one kind or another and may wish to sequentially visit said hyperlinks in an orderly manner. That manner may be performed manually and/or by a passive “screen-show” type of mechanism. 
         [0004]      FIG. 2  illustrates the prior art as it applies to a common navigation process. The web browser  201  provides at least one hyperlink of interest  202 . In the example illustrated in  FIG. 2 , there are at least two hyperlinks of interest,  202  and  209 . Clicking a first hyperlink  202  causes navigation  203  of the web browser to a new target page  204  or section. In this invention, a hyperlink can refer to a distinct URL that leads on current page or off-page. The invention is not limited to the real target for a hyperlink. It will operate properly according to the specification of the hyperlink. After viewing said web page, the user can use the “Back” button  205  to navigate to the earlier web page  201 , thus revisiting it. Only then is the next target hyperlink visible  209  for the user to click  206  to invoke the display of another article of web page  207 . To advance to additional web pages, the user may again return to the primal page  201  via clicking on back navigation  208 , and continue the process. 
       BRIEF SUMMARY OF THE INVENTION 
       [0005]    A method, system and program storage device for browsing hyperlinked documents are provided. A method in one aspect may include enabling navigating from a document having a plurality of hyperlinks to a document associated with one of said plurality of hyperlinks; and enabling navigating directly from said document associated with one of said plurality of hyperlinks to another document associated with another one of said plurality of hyperlinks using one or more of a plurality of defined elements. System and program storage device for performing the above methods are also provided.

     DETAILED DESCRIPTION 
       [0014]    A method and apparatus of the present disclosure in embodiment allows a user to automatically enter a mode wherein a hyperlink on a selected web page can be activated and subsequently obtained and displayed by the browser. Additionally, the browser may be in a state wherein the list of hyperlinks of said page are remembered such that subsequently depressing assigned navigations keys may cause: 1) pop-up to the higher level as is customary; 2) navigate to the upper web page&#39;s next defined hyperlink, and/or 3) navigate to the upper web page&#39;s prior defined hyperlink. In the latter two defined steps, the step of navigating “back” to reach the upper web page again, then selecting the identified hyperlink may be avoided. The method and apparatus of the present disclosure may be useful for browsing photo libraries, news articles that are listed on a web page, and any similar case, in which there are links clustered in any fashion on a web page. The system also permits nesting the operation such that the user may select the hyperlink leading to another web page containing hyperlinks and in like fashion allows “diving” into the depths of pages and forward and reverse navigation. 
         [0015]      FIG. 3  illustrates web browser page navigation using a method of the present disclosure in one embodiment. The navigation process shown in  FIG. 3  allows a user to visit successive hyperlinks by providing a link function  302 . The invoked web browser  301  displays a page with at least two hyperlinks of interest  303  and  309 . Selecting a first hyperlink  303 , the user sees a target page  305  subsequent browser navigation action  304 , then, depressing a defined key (for example, a function key such as FS) or combination of keys would allow the navigation  306  to the primal page&#39;s next hyperlink target  307  without the repeated encumbering navigation to the primal page each time. Similarly, while viewing the target  307  the user can, by depressing a defined key (for example, a function key such as F9) or combination of keys, cause navigation  308  to the preceding page  305  again. A third action (for example, depressing the “Esc” key) can cause navigation  310  from any sibling page to the higher page containing the list of hyperlinks  301 . This is called a “popup to parent page”. The standard navigation keys  102 ,  103  would simply return to a prior-shown web page in the manner consistent with the current art. 
         [0016]      FIG. 7  illustrates stacking the state of the browser and the particular list of URLs that exist on any web page in one embodiment. It illustrates a LIFO (last in first out) stack operation with state information. The information in the stack  706  in one embodiment includes: 1) the list of hyperlinks (URLs)  708  embedded in the web page currently being browsed, along with a pointer  709  that tracks the selection of the URL  710  to display, and 2) the URL of the (“parent”) page  711  from which the list (1) was created. The system and method of the present disclosure, however, is not limited to utilizing the stack operations illustrated in  FIG. 7 . Rather, other methods may be used to preserve or manipulate information for navigating among different hyperlinks. 
         [0017]      FIGS. 5 and 6  illustrate the system and method of the present disclosure in embodiment. Referring to  FIG. 5  with reference to stack operation shown in  FIG. 7 , an internet browser is invoked  501  and navigates (that is, loads the web page) for the home location  502 . Once loaded, the page is displayed and the browser awaits input from the user  503 . The user events may comprise largely keyboard or mouse operations. The present invention is not particularly restricted as to the plurality of user inputs, and may include events not listed herein (example: mouse-over events). Events of interest get filtered as they occur. For example, a mouse click on a hyperlink  504  invokes the pushing  702 ,  703  of the URL  711  of the currently displayed web page  507  (designated as Parent URL) onto a LIFO stack  706 . Next a list is formed for all hyperlinks identified on the page, and the list  708 , along with a marker  709  as to the selected entry  710  is pushed onto the stack  508 ,  701 ,  703 . Although both the Parent URL  705  and the List  704  are in the stack, the means described here still can access these without removal from the stack. Next, the internet browser is made to navigate to the selected (also, “marked”) hyperlink URL  509  and displays that page  503 . 
         [0018]    If the input  503  is not a hyperlink mouse click  504 , but is one of the assigned special key assignments  505 , then a filtering process is done as shown in  FIG. 6 , beginning with entry at  601 . First, for example, if the stack  706  is empty  602 , then the key is ignored  609  and the process exits at  611  with resumption of waiting for an input event at  503 . 
         [0019]    If the stack is not empty  602 , the following processing may occur in one embodiment:
       1. If it is the link pop-up key  603 , then at  606 , the latest list  704  in the stack is popped  707  and discarded. Then, at  612 , the Parent URL  705  (also annotated as  711  in  FIG. 7 ) is popped  707  and used as the target URL at  607  for browser navigation at  503  (via  611  shown in  FIGS. 6 and 511  shown in  FIG. 5 ). The web page is loaded and displayed and further events are awaited  503 .   2. If it is the reverse link key  604 , the marker  709  is moved to an earlier entry (with wrap-around) and that hyperlink URL is navigated to at  608 . As before, the web page is loaded and displayed and further events are awaited at  503 .   3. If it is the forward link key  605 , the marker  709  is moved to a later entry (with wrap-around) and that hyperlink URL is navigated to  610 . As before, the web page is loaded and displayed and further events are awaited at  503 .   4. As customary in the art, the condition that the key is misidentified  605  in one embodiment may result in it simply being ignored  609 . The process continues awaiting user input  503 .       
 
         [0024]    Assigned keys need not be limited to pop-up, reverse or forward keys. For example, other keys may be assigned to navigate to various URLs on the URL list  708 . For instance, there may be assigned a specific key to navigate to a specific URL on the list, etc. Referring back to  FIG. 3 , other events invoked at  503  are processed customarily at  506 . 
         [0025]    The present invention is not limited to the specifics of a web browser page layout. For example, there can be tabbed bodies of web pages and other navigational aids which in no way encumbers the mode and application of the present invention. Hyperlinks as referred to herein may comprise text or graphic areas that provide navigation results when activated. The present invention is not dependent on the mode or form of hyperlinks, including those that may be indirectly invoked via the execution of code steps embedded in web pages. The present invention is not dependent on whether one hyperlink is necessarily grouped with other hyperlinks of similar form, hence potentially similar interest. These are aesthetic dependencies and also somewhat determined by the web page author in anticipation for what hyperlinks may be of interest. In the present disclosure, clicking a hyperlink is identical in concept to activating a hyperlink. The present invention is not dependent on the use of any particular pointer method at the user&#39;s disposal. The present invention is not limited to only web content. It applies equally to any hypertext documentation reader, thus applicable to any document containing embedded links that when activated, causes a jump to the corresponding target. 
         [0026]      FIG. 4  is a diagram illustrating a state transition in one embodiment of the present disclosure. Upon activation  401  the browser starts and enters a “neutral state” devoid of remembered prior links as described. The present invention is not limited to this case. For instance, an embodiment may include a stateful restoration of a web page. In addition, including the drilldown into links followed can be a useful and powerful feature. It is assumed that the browser displays some web page in the neutral state  402  and thus will remain there until either the user quits  404  and it terminates  405  or some interaction or process  406  occurs other than the non-navigation events  403 . Given that navigation by following a hyperlink occurs  406 , the browser saves the relevant hyperlinks into a LIFO stack  706  of the current (parent) web page  702  at  407 . The state transitions  408  to a condition of being in a hyperlinked state  409 . The hyperlinked state in one embodiment is characterized by the presence of the parent URL  705  and the list of hyperlinks  704  on a LIFO stack  706 . Just as described in the neutral state  402 , there can be non-link interactions or processes  410  which preserve the hyperlinked state. For example, a user can interact with the dashboard and cause a jump to a direct URL  415  hence returning the browser to a neutral state, showing a new web page. A user may choose to link to an adjacent link, that is another hyperlink from the parent page. This excursion  416  allows navigating to an adjacent link  417 , thus maintaining the hyperlinked state  418  transition to  409 . Other means can provide the excursions to the forward/reverse links. The present invention is not limited as to how the invocation can occur. For example, the browser can contain an automatic “screen show” feature to invoke the excursions in some manner, just as easily as if done by human interaction. Aside from ending the browser program, it could be expected that the user leaves the hyperlinked state either to simply “popup”  707 , of the current hyperlinked state by popping and discarding the List  704 , and then popping and using the Parent URL  705  to reload the browser, via transition  411 ,  412 . If the stack still contains at least one Parent URL and List, the transition  413  allows continuation of the hyperlinked state  409 . Otherwise, there is a reversion  414  to the neutral state  402 , wherein the browser awaits input for example, from the user or an automated process. Further, there can be actions that perpetuate the neutral state  403  without evoking the selection of a hyperlink  406 , and the browser program can be terminated  404 ,  405 . 
         [0027]      FIG. 8  is a diagram of the “screen show” mechanism of navigating to hyperlinked documents. Given invocation, while the prior-described apparatus is in the hyperlinked state (i.e., there is a Parent URL, and a list currently in the non-empty LIFO stack  706 , processing begins at  801 . At  802 , the valid state of the program apparatus is verified, and if the state is not valid, for example, by checking whether the stack is empty, the invocation is not started but terminated at  806 . However, if verified, then processing enters a looping state wherein a check is made for an event that signifies “screen show” termination  803 . While looping, the following processing steps occur in one embodiment: 1) A time delay for processing is performed, thus allowing for the observer to see the screen without intervention  804 ; and 2) a marker ( FIG. 7 ,  709 ) is advanced as described for the forward link key action as illustrated in  FIG. 6 ,  605 . The process continues with resumption of termination test  803 , repeating until signaled or until the program itself is terminated. In one embodiment, the screen show may terminate at the end of the URL list ( FIG. 7 ,  708 ). In another embodiment, the screen show may continue after encountering the end of the URL list by wrapping around to the beginning of the URL list. 
         [0028]    The system and method of the present disclosure may be implemented and run on a general-purpose computer or computer system. The computer system may be any type of known or will be known systems and may typically include a processor, memory device, a storage device, input/output devices, internal buses, and/or a communications interface for communicating with other computer systems in conjunction with communication hardware and software, etc. 
         [0029]    The terms “computer system” and “computer network” as may be used in the present application may include a variety of combinations of fixed and/or portable computer hardware, software, peripherals, and storage devices. The computer system may include a plurality of individual components that are networked or otherwise linked to perform collaboratively, or may include one or more stand-alone components. The hardware and software components of the computer system of the present application may include and may be included within fixed and portable devices such as desktops, laptops, and servers. 
         [0030]    The embodiments described above are illustrative examples and it should not be construed that the present invention is limited to these particular embodiments. Thus, various changes and modifications may be effected by one skilled in the art without departing from the spirit or scope of the invention as defined in the appended claims.
