Previewing prominent features of remote documents

## Abstract

A document previewing system includes a display device including a user interface and a document previewing engine coupled to the display device. The document previewing engine is configured to download an outline of a document including outline features and filler content in between the outline features. The filler content replaces secondary content of the document. The document previewing engine is further configured to display the outline on the display device, and download the secondary content corresponding to an outline feature in response to a user navigating to the outline feature and the outline feature displaying on the display device for a period of time.

## Background
BACKGROUND
Transmitting data over a network may be costly, time consuming, and unnecessarily consume bandwidth. Many users seek to reduce the amount of data downloaded onto devices because providers limit data usage or charge based data usage. In some instances, documents or data sets are too large to be loaded onto a local machine over a network without significant delay. A common solution is to download only a first portion of the document or data set while also providing the impression to the user that the entire document is loaded when it is not. Navigation further through the document or data set prompts a request for more data from the server and continues the download. While such a solution helps reduce unnecessary downloads, users only interested in information located in the middle or near the end of the document or data set still download more than needed as they navigate through the document. Additionally, users unnecessarily increase data usage that may be costly and time consuming.

DETAILED DESCRIPTION
It will be readily understood that the components of the embodiments as generally described herein and illustrated in the appended figures could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of various embodiments, as represented in the figures, is not intended to limit the scope of the present disclosure, but is merely representative of various embodiments. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by this detailed description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
Reference throughout this specification to features, advantages, or similar language does not imply that all of the features and advantages that may be realized with the present invention should be or are in any single embodiment of the invention. Rather, language referring to the features and advantages is understood to mean that a specific feature, advantage, or characteristic described in connection with an embodiment is included in at least one embodiment of the present invention. Thus, discussions of the features and advantages, and similar language, throughout this specification may, but do not necessarily, refer to the same embodiment.
Furthermore, the described features, advantages, and characteristics of the invention may be combined in any suitable manner in one or more embodiments. One skilled in the relevant art will recognize, in light of the description herein, that the invention can be practiced without one or more of the specific features or advantages of a particular embodiment. In other instances, additional features and advantages may be recognized in certain embodiments that may not be present in all embodiments of the invention.
Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the indicated embodiment is included in at least one embodiment of the present invention. Thus, the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.
While many embodiments are described herein, at least some of the described embodiments facilitate previewing remote documents efficiently by reducing unnecessary and sometimes costly downloads. Documents and data sets downloaded over a network may be extremely large. Downloading large documents takes time, occupies bandwidth, and may be costly for users with restrictive download limits. In many instances, a user may be interested only in a small portion of the document or data set, making much of the download unnecessary.
In some conventional methods, downloading a large document or data set involves downloading only the first portion of the document. In some instances, the document continues downloading automatically. In other instances, as the user scrolls or navigates through the document, the scrolling prompts the local machine to continue downloading the document. In many instances, the size and position of a scroll box within a scroll bar is estimated to give the impression to the user that the entire document has been downloaded onto a local machine when only the first portion has been downloaded. While this conventional method solves problems inherent in downloading large documents and data sets, there are still problems that the conventional method does not solve. When a user is interested only in a portion of the document, the user may unnecessarily download large segments of the document. In the case where the interested portion is located at the end of a document, the user may need to download the entire document scrolling to the end because the user cannot tell where to navigate in the local document. In another case, the user may know the desired portion is located in the middle of a document and may blindly scroll halfway down the document only to realize the user downloaded an unwanted portion. The user is unable to tell where to navigate in the local document. Downloading the unwanted portions may prove costly and may accelerate reaching download limits.
Some embodiments described herein involve first downloading an outline of a document or data set. In some embodiments, the outline may include prominent features of the document or data set and may include filler content or filler data in between the prominent features. The prominent features or outline features allow the user to recognize the content not yet downloaded and the location of the content within the document. Some embodiments reduce the time to download by limiting the size of the outline. Some embodiments allow the user to navigate through the document or data set, browsing through the outline features. Some embodiments reduce unnecessary downloads by downloading only the content corresponding to the outline feature displayed when the user stops navigating. In some embodiments, the user will not download the entire document as the user scrolls through the document and the user will not blindly download portions of the document. First downloading an outline of a document reduces the time to download and saves bandwidth. The outline features allow the user to quickly and accurately locate and download only the desired portions of the document. Reducing unnecessary downloads save time, money, and bandwidth. Quickly finding the desired portion of a document or data set reduces user frustration and increases user satisfaction.

The functionality of the document previewing engine 210 may be implemented by computer program instructions stored on the computer memory device 202 and executed by the processing device 204 such as a CPU.
A user interface 214 is displayed on the display device 212. The display device 212 may be any display device 212 for a computing device. The user interface 214 may be part of an operating system for the computing device and may allow a user to interact with the operating system. The operations described herein may be associated with one or more applications configured to operate within the operating system. In some embodiments, the display device 212 and the user interface 214 are part of the local machine 106.
In some embodiments, the document previewing engine 210 is configured to download an outline of a document comprising outline features and filler content in between the outline features. In some embodiments, the filler content replaces secondary content of the document. In order to limit the amount of data downloaded, the filler content replaces the secondary content of the document or data set. In some embodiments, the filler content is stored on the local machine 106 in order to limit the amount of data downloaded. The filler content may occupy the same amount of space as the secondary data to accurately portray the amount of secondary data that is downloaded. In some embodiments, the document previewing engine 210 is further configured to display the outline on the display device. The document previewing engine 210 may be further configured to download the secondary content corresponding to an outline feature in response to a user navigating to the outline feature and the outline feature displaying on the display device for a period of time.
In some embodiments, the outline includes outline features of the document or data set. In some embodiments, the outline features are only the prominent features of the document or data set. The outline features may be section headings, subsection headings, the first sentence of a section, images, chapter headings, data field headings, page indicators, titles, abstraction index, words, cell headings, or other features of a document or data set recognizable to a user. In some embodiments, the outline features allow the user to easily recognize the portion of the document or data set that the user wants to download without downloading the rest of the document or data set. The outline features or recognizable items allow the user to understand the skeletal structure of the document or data set without downloading the entire document or data set. In some embodiments, the outline features are spaced throughout the document or data set with filler content in between the outline features replacing the content corresponding to each outline feature. For example, the outline features may be the section headings of a report. The initial download will include only the section headings of the report with fake text replacing the body of the report. The user may navigate through the outline by scrolling and reading the section headings. As the user stops navigating at a section heading the body of the paper corresponding to the section heading will be downloaded and replace the fake text initially loaded with the outline. The fake text may be another type of filler content such as images, lines, graphics, white space, or space. In this example, the user will only download the sections of the paper that interest the user instead of downloading the entire paper as the user scrolls through the paper, thus reducing unnecessary downloads and freeing bandwidth.
In some embodiments, the document previewing engine 210 is further configured to display a scroll preview box during navigation, and display the outline of the document in the scroll preview box. The scroll preview box may be smaller in size than the document allowing the initial download to be lower resolution and ultimately a lower data amount. In some embodiments, the outline is displayed only in the scroll preview box. In some embodiments, the document previewing engine 210 is further configured to display the scroll preview box only during navigation. Navigation may be scrolling through a data set or document by use of a mouse, a scroll bar, keyboard keys, an input gesture on a touch sensitive screen, or other means well known.
In some embodiments, the outline includes a first outline feature of the document and a first filler content that replaces a first secondary content corresponding to the first outline feature of the document. In some embodiments, the outline further includes a second outline feature of the document, and a second filler content that replaces a second secondary content corresponding to the second outline feature. In some embodiments, the filler content is between the outline features. The document previewing engine 210 may be further configured to download the first secondary content in response to the user navigating to the first outline feature and the first outline feature displaying on the display device for a period of time.
The document previewing engine 210 may be further configured to display the outline in a document viewer. In some embodiments, the document viewer includes a scroll bar and a scroll box. The document previewing engine 210 may be further configured to link the secondary content to a position of the scroll box within the scroll bar, and download the secondary content in response to the user sliding the scroll box to the position and the scroll box remaining in the position for a period of time.
In addition to the advantages which may be achieved by implementation of the individual components of the document previewing system 108, some embodiments of the document previewing system 108 provide additional advantages over conventional technology. For example, some embodiments of the document previewing system 108 allow a user to quickly download an outline of a document or data set. The outline allows a user to quickly identify only the portions of the document or data set relevant to the user's query. Some embodiments reduce or eliminate the possibility of an error in downloading data not desired and reduce the amount of data downloaded as well as decrease costs and increase available bandwidth.
FIG. 3 depicts one embodiment of a document 300 including outline features 302-304 and secondary content 306-308. In some embodiments, the document 300 may be a data set. The document 300, in some embodiments, includes outline features 302-304. Some embodiments include secondary content 306-308. In FIG. 3, the secondary content 306 corresponds to the outline feature 302 and the secondary content 308 corresponds to the outline feature 304. The content of the document 300 relates to maintenance of a car. A user may be interested only in a portion of the comprehensive document 300. Downloading the entire document 300 onto a local machine 106 may be unnecessarily expensive depending on a data plan and may be time consuming. Some embodiments allow the user to initially download only the outline features 302-304 of the document 300. The user then may scroll or navigate through the document 300 to find the outline feature 302-304 that the user desires before downloading. Some embodiments include a document viewer 310. In some embodiments the document viewer 310 includes a scroll bar 312, and a scroll box 314 to assist in navigation of the document 300.

In some embodiments, the outline includes filler content 316 and 318 in place of the secondary content 306 and 308 of the document 300. The filler content 316 and 318 replaces the secondary content 306 and 308 on the initial download decreasing the amount of data downloaded and the bandwidth occupied. In some embodiments, the filler content 316 and 318 is downloaded with the outline features 302 and 304. In some embodiments, the filler content 316 and 318 is already stored on the local machine 106. In some embodiments, the application used to view the document 300 designates the amount of filler content 316 and displayed. In some embodiments, the download directs the amount of filler content 316 and 318 to be displayed with the each outline feature 302 and 304. The user may navigate through the document 300 by use of the scroll box 314 and scroll bar 312 or in another known method for navigating through a document or data set. As the user navigates, the display changes showing various outline features 302 and 304. In some embodiments, as the user locates the interested outline feature 302 and stops navigating the secondary content 306, shown in FIG. 3, which corresponds to the outline feature 302 is downloaded. In some embodiments, the second download occurs in response to the outline feature 302 displaying on the display device 212 for a period of time. In some embodiments, the outline feature 302 must occupy a certain location on the display to initiate the second download. In some embodiments, the filler content 316 and 318 may be fake text, lines, graphics, images, white space, or other representation of the secondary content 306 and 308 which corresponds to the outline feature 302 and 304. FIG. 4 depicts one embodiment of the document 300 after the initial download and FIG. 3 depicts the document 300 after the download of secondary content 306 and 308.
