BACKGROUND

1. Technical Field

The field relates to operating systems, software applications and user interface devices, and, more particularly, to a system, method, apparatus or non-transitory computer program product for displaying a scrollable document in a browser window that permits varying scroll rates of corresponding display content.

2. Background

Applications are commonly used with computational devices, such as, laptops, smartphones, tablet computing devices, personal digital assistants (PDAs), etc. Applications allow a user to access information sources, webpages, games, and other virtual tools. Applications are usually accessed and viewed in a display browser window. Navigation tools commonly associated with a browser window generally include a scroll bar, address window, main display area and other additional tabs and display options.

In one example of operating a computing device, a user may access a document via his or her smartphone device. When accessing the document, the user may select a particular desktop icon, such as a browser icon, and launch a particular application, such as a browser application, and download the document from a remote location. Alternatively, the document may already be downloaded on the user\'s smartphone and may be accessed by a user initiated selection operation. Once the user has opened the document in a browser window, the browser may provide a default display configuration for the document to be viewed, navigated, manipulated, modified, etc.

The display size of the document is limited by the size of the user display window. The document may span multiple pages and may be viewable only one page at a time. Furthermore, the limited viewing space on the newer pocket and travel-sized display devices requires increasingly simple and prompt viewing options for the users\' satisfaction.

BRIEF

SUMMARY

In an embodiment, a computer-implemented method may include certain operations to display and scroll a document. Operations may include displaying a first page of a portable document format (pdf) document on a browser window, associating respective thumbnails with each of a plurality of pages in the pdf document, and displaying two or more of the respective thumbnails overlaid on the first page. Other operations of the method may include receiving an indication to scroll the pdf document in a first direction, scrolling the plurality of pages of the pdf document at a first rate in the first direction, and scrolling the respective thumbnails of each of the plurality of pages at a second rate, different than the first rate, in the first direction.

Another embodiment may include a system that includes a scroll adjustor, implemented with a computing device, configured to perform certain operations. The operation may include to display a first page of a portable document format (pdf) document on a browser window, associate respective thumbnails with each of a plurality of pages in the pdf document, and display two or more of the respective thumbnails overlaid on the first page. Further operations may include to receive an indication to scroll the pdf document in a first direction, scroll the plurality of pages of the pdf document at a first rate in the first direction, and scroll the respective thumbnails of each of the plurality of pages at a second rate, different than the first rate, in the first direction.

Further embodiments, features, and advantages of the invention, as well as the structure and operation of the various embodiments of the invention are described in detail below with reference to accompanying drawings.

DETAILED DESCRIPTION

Embodiments described herein refer to illustrations with reference to particular applications. It should be understood that the invention is not limited to the embodiments. Those skilled in the art with access to the teachings provided herein will recognize additional modifications, applications, and embodiments within the scope thereof and additional fields in which the embodiments would be of significant utility.

In the detailed description of embodiments that follows, references to “one embodiment”, “an embodiment”, “an example embodiment”, etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to effect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.

FIG. 1A illustrates an example browser window displaying a document, according to an example embodiment. Referring to FIG. 1A, the browser window 10 is illustrated as displaying the contents of a document that have been opened by a user selection operation. The user may download a document from the Internet, a remote file server, to their computing device via a document receiving application, such as an email application. The document may be downloaded and selected for viewing either at separate times or contemporaneously. The user may select the document by an icon or thumbnail indicator associated with the document that is displayed on the user\'s display device. The selection operation may include selecting to open the file for viewing by selecting an open feature, or by performing a selection operation on a mouse device or touch pad/touch screen device. As a result, the document may open and appear viewable to the user via a browser plug-in or a browser-based document format.

Referring to the browser window 10, FIG. 1A further illustrates an address bar or document indication field 20 along with a variety of adjacent user options related to the browser 10 (e.g., refresh, helpdesk, bookmarks, tools, etc.). In this example, the document has been opened for viewing on a primary portion of the browser display area 30. The first page of the document is shown as a destination vacation photograph that has been formatted as part of a document entitled “vacation.pdf.” The document includes images as well as text and spans multiple pages; however, only one page is presently viewable. As part of the same browser window, a column of icons or thumbnails 40, 42, 44 and 46 are also illustrated as preview windows corresponding to the content of the main display area or the primary portion of the browser display area 30.
