Patent Application
20110055691
This is directed to previewing several types of documents using a single preview application. In particular, this is directed to a single preview application for previewing and searching through different types of documents opened by different applications.
Using an electronic device, a user can preview different documents without opening the application used to create, edit, or revise the document. For example, a preview application can be used to allow a user to preview files typically opened using Microsoft Word and Microsoft PowerPoint (applications available from Microsoft Corporation of Redmond, Wash.), Keynote and Pages (applications available from Apple Inc. of Cupertino, Calif.), and Acrobat (application available from Adobe Systems Inc. of San Jose, Calif.) using a single application. Because the preview application may have limited functionality when compared to the applications used to create or edit the documents (i.e., the preview application may only allow a user to view documents), the preview application can load faster than the applications and provide a more efficient use of the device resources for previewing documents.
Each time a user may wish to preview a document, the user can direct the electronic device to open distinct preview windows for each document. For example, the user can direct the electronic device to open a first preview window for an image document (e.g., a .tiff document), a second preview window for a first text document (e.g., a first .pdf document), and a third preview window for a second text document (e.g., a second .pdf document). This approach, however, may be burdensome when a user wishes to review information simultaneously in several documents via the preview application (i.e., this approach may force the user to switch between preview windows). In addition, to search for a particular term in each of the documents, the user may be required to perform individual searches in each window.
This is directed to systems, methods and computer-readable media for providing a preview application operative to simultaneously preview several documents. In particular, this is directed to a preview application for simultaneously previewing and searching through several documents of one or more types.
Using a display, an electronic device can display different documents generated using different applications. The application associated with each document can be used to open, view, edit, save, or convert the document, or perform any other operation with or on the document. When a user wishes to view several documents of different types (e.g., associated with different applications), the user may be forced to execute each application. This can be time and resource consuming, as each application may provide more features than the user actually needs, but that nevertheless are enabled when the application is loaded. As an alternative, the electronic device can use a dedicated preview application that is operative to display different types of documents that are created using other applications. The preview application may have limited functionality, and for example not allow a user to edit a document. Because of its limited functionality, however, the preview application can allow a user to view several documents of different types using a single application in a resource efficient manner.
The preview application can display several documents using different approaches. In one implementation, the electronic device can display each document in a separate window. Alternatively, the electronic device can display several documents of one or more type in the same window. The electronic device can distinguish each document using any suitable approach, including for example by placing each document in a separate section or area of the window (e.g., each document is placed in a book). In some embodiments, each document can be displayed via a transparent cover that can be flipped open to access the pages within the document. The preview application can display the pages of each document using different approaches. In one embodiment, the preview application can display a current page in a large window, and the other pages of each document in a one-dimensional array (e.g., a vertical column of several documents, where each document can include several displayed pages). In another embodiment, the preview application can display each document and its respective pages in a two-dimensional array (e.g., each document and its pages can be displayed in one or more rows of the preview application).
A user can search for particular terms in each of the documents displayed in the preview application using a single interface. The preview application can identify the pages in each of the documents that include the search term, and display only the identified pages to the user for review. The preview application can in addition include an indication of the number of hits in each page (e.g., a search rank indicating the number of hits on each page).
The above and other features of the present invention, its nature and various advantages will be more apparent upon consideration of the following detailed description, taken in conjunction with the accompanying drawings in which:
This is directed to a preview application for simultaneously previewing several documents. In particular, this is directed to displaying pages of several documents in different configurations, and providing search results in the preview interface.

The electronic device can display any suitable document or pages of documents to a user of the device.
The user can select to preview any suitable number of documents. In the example of
To view the individual pages of a document, the user can direct the device to open the book associated with the document.
The preview application can display any suitable document page in display area 302 after opening a document (e.g., opening the book generated for a document). In some embodiments, the preview application can automatically display a page of the opened document. In another embodiment, the preview application can display the document or page identified by a selection option or highlight region (e.g., highlight region 320).
In some embodiments, the preview application can display documents and their associated pages in a two-dimensional array (in addition to in instead of the one-dimensional column of displays 200 and 300,
In some embodiments, a user may wish to search for particular terms in one or more documents accessed by the preview application. For example, a user may wish to find a term or phrase in several documents to determine which of the documents to open and edit.
The user can search for one or more particular terms using any suitable approach, including for example by entering a search term in search field 520. In response to receiving the search request, the electronic device can identify all of the instances of the search term in each of the documents of display area 502, and filter the pages of each individual document to only display those pages 513 that include at least one instance of the search terms. The preview application can provide an indication of the number of hits in each displayed page using any suitable approach, including for example by highlighting hits within each text page, or via search rank indicator 522 (e.g., a bar of varying length, the length determined from the number of hits). In some embodiments, the preview application can initially limit the number of displayed pages (e.g., to two lines) to ensure that the user can view results from every document. The user can, by providing a corresponding instruction, expand the displayed results to include more or all of the hits in each previewed document.
The search results can be ordered using any suitable approach. In some embodiments, the search results can be displayed in page order of the previewed document. Alternatively, the search results can be displayed by number of hits.
At step 708, the electronic device can determine whether an instruction to open a book was received. For example, the electronic device can detect a user provided an instruction to view the pages of a previewed document. If the electronic device determines that no instruction to open a book was received, process 700 can return to step 708 and continue to monitor for an instruction to open a book. If, at step 708, the electronic device instead determines that an instruction to open a book was received, process 700 can move to step 710.
At step 710, the electronic device can animate a cover opening on the book. For example, the electronic device can animate a transparent or translucent page opening from over the first page of the document and folding around the displayed spiral binding. At step 712, the electronic device can display the pages of the book in an array. For example, the electronic device can insert the pages of the document within a one-dimensional array of documents being previewed. As another example, the electronic device can insert the pages in a two-dimensional array (e.g., pages in successive rows started with the cover page of the document). Process 700 can then end at step 712.
If, at step 806, the electronic device instead determines search terms were received, process 800 can move to step 808. At step 808, the electronic device can identify pages in the displayed documents that have the received search terms. For example, the electronic device can identify instances within the pages of each document that match the search terms. At step 812, the electronic device can filter the display of pages to display only the identified pages that include the search terms. For example, the electronic device can direct the preview application to automatically remove from display pages of documents that do not include the search terms. At step 814, the electronic device can order the filtered pages in the display. For example, the electronic device can order the pages based on the order of the pages within each document. As another example, the electronic device can order the pages based on the number of hits on each page. In some embodiments, the electronic device can keep each document distinct, or can intermingle the pages of each document that include the search terms in the display (e.g., based on the ordering used for the identified pages). Process 800 can then end at step 816.
If, at step 908, the electronic device instead determines that the selected document is indexed, process 900 can move to step 912. At step 912, the electronic device can query the index and identify matches to the search terms. At step 914, the electronic device can determine whether there is a match in one of the indexed documents. If the electronic device determines that there is no match, process 900 can return to step 906 and select the next document. If all documents have been selected, process 900 can move to step 918.
If, at step 914, the electronic device instead determines that there is a match with one of the indexed documents, process 900 can move to step 916. At step 916, the electronic device can add the page or pages having the match to a result list. In some embodiments, process 900 can then return to step 906 and select the next document until all documents have been selected, and subsequently move to step 918. Alternatively, process 900 can move directly to step 918. At step 918, the electronic device can clear the sidebar of all booklets. For example, the electronic device can clear column 210 of display 200 (
If, at step 922, the electronic device instead determines that a booklet has been displayed, process 900 can move to step 926. At step 926, the electronic device can add a page for the result to the booklet corresponding to the document or page, and sort the page. For example, the electronic device can sort the page by page number within the document, but search result, or using any other scheme. Process 900 can them return to step 920 to select another page from the results list.
