## Background
FIELD OF THE INVENTION
Embodiments of the invention generally relate to the field of user interface, and more specifically to a method and system for navigating between pages.
BACKGROUND OF THE INVENTION
Electronics documents are generally lengthy, and the complete document cannot be accommodated into available display area on a computer user interface. To navigate from one page to another continuously, a scrollbar can be used. Also, to navigate from a current page to another page in increments, generally a previous page or next page option is provided in the user interface. However, to navigate from a current page to one of the intermediate pages, the user has to select the option of previous page or next page a number of times, depending on where the page of interest lies in the document. For example, in a document containing 10 pages, if a user wants to navigate from page 3 to page 8, the user has to choose the option of next page five times. In such situations, the present scrolling options have been found to be less optimal. There is a need for a navigation system that allows the user to easily choose the page to navigate to, without having to go back and forth with the scrollbar or use the previous page/next page options.

Computer user interface 100 illustrates exemplary methods and systems of the present invention. Computer user interface 100 is typically a means for providing an interface for a user to interact with a machine. Behavior of the computer user interface may typically be governed by computer-executable instructions that are executed as a user interacts with the user interface. Computer user interface 100 generally refers to any information that a program presents to the user, and depicts various types of relationships between user interface (UI) elements that the user employs to control the program. UI elements include animation control, pop-up menu, progress bar control, check box, push button, radio button, scrollbar, drop down menu, tooltip, and the like.
Computer user interface 100 displays a portion of current page 102 of a document. The document includes a plurality of pages or items that represent a collection of information. Typically, the pages or items of the document may include text, picture, sound, video, tables, charts and the like. Current page 102 is displayed on a viewing area of computer user interface 100. Current page 102 represents one of the plurality of pages or items currently viewed on computer user interface 100.
Computer user interface 100 includes scrolling section 104. Scrolling section 104 is typically designed as a long rectangular area (e.g. scrolling area) on one or more sides of the viewing area on computer user interface 100. Scrolling section 104 typically includes a scrollbar (e.g. pagination scrollbar) that can be moved along the scrolling area, to move the document. Scrolling section 104 allows the user to scroll the scrollbar in vertical directions (e.g. upwards or downwards), to view the portions of the document that are currently not displayed on computer user interface 100. In an embodiment, scrolling section 104 allows the user to scroll the scrollbar in horizontal directions, to view the portions of the document that are currently not displayed on computer user interface 100. Scrolling section 104 may include a previous-arrow section to move from current page 102 to a previous page of the document, and a next-arrow section to move from current page 102 to a next page of the document.
Scrolling section 104 includes pagination scrollbar 106. Pagination scrollbar 106 is used to change the viewing area of the document, thereby changing current page 102 that is being viewed. Pagination scrollbar 106 is typically a UI element with which, continuous documents can be scrolled and viewed even if the document cannot be accommodated into the available display area on a computer user interface 100. Pagination scrollbar 106 may also be dragged to a position intermediate between two pages. Pagination scrollbar 106 may be incorporated into any kind of computer display. Pagination scrollbar 106 may also be operable to slide from the first portion of the document to the second portion of the document. Page number display area 110 displays the page number of current page 102 that is being viewed on computer user interface 100. For example, in FIG. 1A, page number display area 110 displays the page number ‘6’ that is currently being viewed on computer user interface 110. In other embodiments, page number display area 110 may also provide other information about the portion of the document that is currently being viewed in addition to the page number.
In one embodiment, pagination scrollbar 106 includes a first navigation selection area 108, second navigation selection area 112 and the page number display area 110. First navigation selection area 108 and second navigation selection area 112 are operable based on a user action.

For instance, first navigation selection area 108 may display a first instance of the page selection menu and second navigation selection area 112 may display a second instance of the page selection menu, based on a user action. The first instance of the page selection menu and the second instance of the page selection menu may include a list of menu items. In another embodiment, pagination scrollbar 106 includes a first portion of the navigation selection area and a second portion of the navigation selection area.
In another embodiment, pagination scrollbar 106 includes a first half portion located along a direction of the pages preceding current page 102 and a second half portion located along a direction of the pages succeeding current page 102. A first portion of the navigation selection area occupies a part of the first half portion of pagination scrollbar 106 and a second portion of the navigation selection area occupies a part of the second half portion of pagination scrollbar 106. In yet another embodiment, pagination scrollbar 106 includes a first end portion located along a direction of the pages preceding current page 102 and a second end portion located along a direction of the pages succeeding current page 102. The first portion of the navigation selection area occupies a part of the first end portion of pagination scrollbar 106 and the second portion of the navigation selection area occupies a part of the second end portion of pagination scrollbar 106.
User actions may include a hover action that is performed on first navigation selection area 108 or second navigation selection area 112. For instance, first navigation selection area 108 displays first page selection menu 114 based on the user action performed on first navigation selection area 108. Second navigation selection area 112 displays second page selection menu 116 based on the user action performed on second navigation selection area 112. It will be appreciated that a variety of user actions may be performed to implement the teachings of the invention as described herein. The location of navigation selection areas may correspond to the direction of navigation associated therewith. For instance, first navigation selection area 108 might be operable for navigating to pages preceding current page 102 because it is located in the part of pagination scrollbar 106 pointing to the preceding page. Second navigation selection area 112 might be operable for navigating to pages succeeding current page 102 because it is located in the part of pagination scrollbar 106 pointing to the succeeding pages.
A page selection menu is a drop down menu, which is a UI element that typically includes a group of UI elements in the form of a list, which is generally displayed when the title of the drop down menu is activated. In one embodiment, the page selection menus (e.g., 114 and 116), which is presented in response to a user action with respect to one of the navigation selections areas (e.g., 108 and 112), is a page menu. Other menu formats operable for receiving a user selection can be used instead of or in combination with the page menu. First page selection menu 114 includes one or more pagination links, each pagination link correspondingly representing a unique page of the document preceding current page 102. Second page selection menu 116 includes one or more pagination links, each pagination link represents a unique page succeeding current page 102 in the document. These links may include some information to indicate the page number they correspond with. For instance, in one embodiment, first page selection menu 114 includes a list of page numbers correspondingly associated with the pages preceding current page 102, whereas second page selection menu 116 includes a list of page numbers correspondingly associated with pages succeeding current page 102.
In an embodiment, pagination links are hyperlinks. A hyperlink is a UI element that typically indicates a reference in the document. The hyperlink can be considered as a navigation element that allows navigating from a present portion of a document to a portion of the document represented by the hyperlink. For example, a name of a website may be representing a hyperlink that displays the homepage of the website when activated. In an embodiment, the user may click on one of the pagination links displayed on first navigation selection menu 114 or second navigation selection menu 116. In another embodiment, a user may activate the pagination link with an input device to cause navigation to a corresponding portion of the document represented by the pagination link selected. Once a selection is made on the pagination link, the selection is recognized, and controls navigate to the page represented by the selected pagination link. In an embodiment, the controls are navigation controls that recognize the reference of the selected pagination link, and navigate to the page represented by the selected pagination link.
In an embodiment, actions to be performed on activating controls such as first navigation selection area 108, second navigation selection area 112, and the pagination links may be interpreted in combination with instructions to generate results corresponding to the particular combination of user action and the control it was performed on. For example, the actions to be performed may include displaying first page selection menu 114, second page selection menu 116, navigating to a page represented by selected pagination link, and the like. The instructions may receive signals from an input device, and perform the corresponding action. For example, a hover action performed by a mouse pointer on first navigation selection area 108 may be recognized by one or more instructions, and the instructions may generate a corresponding first page selection menu 114. Furthermore, the instructions may recognize the pagination link selected on first page selection menu 114, and perform a navigation action to the page represented by the selected pagination link.
