The disclosure generally relates to document editing.
Creating, maintaining and storing multiple versions of a document is common practice. Maintaining multiple versions of a document allows users or editors of the document to look at the history of a document and review the changes that were made to the document.
Visual comparison of document versions is described. In some implementations, versions of a document can be quickly displayed using a single user input. In some implementations, a displayed page of a version of the document can be replaced by a corresponding page of another version of the document.
Particular implementations provide at least the following advantages: A user can use visual memory to quickly identify differences in different versions of the same document. A user can quickly and easily navigate between document versions.
Details of one or more implementations are set forth in the accompanying drawings and the description below. Other features, aspects, and potential advantages will be apparent from the description and drawings, and from the claims.
Like reference symbols in the various drawings indicate like elements.
In some implementations, graphical interface 100 can be invoked from a document editor application. For example, graphical interface 100 can be displayed in response to the selection of a graphical element (e.g., button, menu item, etc.) of the document editing application. Graphical interface 100 can include content display area 102. For example, content display area 102 can display an image of a page of the document. In some implementations, when graphical interface 100 is invoked, the most recent document version will be displayed. For example, a page from the current working document version can be displayed in content display area 102.
In some implementations, graphical interface 100 can include information area 104. For example, information area 104 can display information about the content currently displayed in content display area 102. Information area 104 can include page number information, such as the page number of the displayed page and the total number of pages in the document. Information area 104 can include document version information, such as a date and time corresponding to when the displayed document version was generated. In some implementations, as the content in content display area 102 is changed, the information in information area 104 can be updated to display information associated with the displayed content. For example, if the next page is displayed (e.g., page 7), information area 104 will be updated to indicate that page 7 is currently displayed. If a different version of the document is displayed, information area 104 will be updated to display version information associated with the displayed document version.
In some implementations, a user can return to the document editing application by selecting graphical element 106. For example, graphical element 106 can be a button which, when selected, causes graphical interface 100 to close. When graphical interface 100 closes, the document editing application can be displayed.
In some implementations, a user can provide input through an input device to cause a different page of the document version to be displayed. For example, the user can use right and left arrow keys to display the next page or the previous page of a version of a document. If the computing device is configured to process touch input, a gesture (e.g., left swipe, right swipe) can be provided by the user to cause the previous page or next page of the document version to be displayed. In some implementations, a user can select one of graphical elements 202 (e.g., right arrow button, left arrow button) to cause the previous or next page of a document version to be displayed. In some implementations, changing pages does not change which version of the document is displayed. For example, a user can sequentially display the pages within a selected version of the document by providing keyboard or touch input, as described above.
In some implementations, a page change animation can be displayed when navigating between pages of a document version. For example, when a user provides input to display the next page of a document version, the current page can be animated so that it appears to slide off of content display area 102, as illustrated by
In some implementations, a user will select a portion of a document to view. For example, spreadsheet applications may not organize content into discrete pages. The units of a spreadsheet file are often worksheets or the like. Often worksheets can include a large amount of data over a large display area. If the worksheet is scaled down to fit within content display area 102, the items within the worksheet may be too small to view and compare. Thus, in some implementations a user will be able to select a portion of a worksheet to compare between versions. For example, a user can use right and left arrow keys (or left and right swipe touch input gestures) to move between worksheets of a spreadsheet file. Within a worksheet, a user can scroll to an area of the worksheet using a combination of keyboard keys (e.g., control button and arrow keys) to display the area of the worksheet within content display area 102.
Alternatively, a user can use a pointer device and a cursor to drag the desired worksheet area into view on content display area 102. For example, the user can click on the portion of the worksheet displayed in content display area 102 and drag the portion of the worksheet out of content display area 102 to display a different portion of the worksheet. In some implementations, interactive graphical elements (e.g., vertical and horizontal scroll bars) can be presented to allow a user to display different portions of a worksheet within content display area 102.
In some implementations, the same page or portion of the document is displayed when navigating between document versions. For example, if page five (5) is displayed for a currently displayed document version and an up arrow key input is received, page five (5) of the next (or previous) document version will be displayed. In some implementations, the page of the next (or previous) document version will replace the page of the currently displayed document version within content display area 102. Likewise, if a portion of a spreadsheet worksheet is displayed in content display area 102, the same portion (e.g., location) of the worksheet will be displayed when the user navigates between versions of the spreadsheet.
In some implementations, graphical interface 300 can include graphical element 302. For example, graphical element 302 can be a heads-up display that presents information about the currently displayed version of the document. Graphical element 302 can be an opaque or semi-transparent overlay displayed over content display area 102, for example. Graphical element 302 can include date and time information corresponding to when the version of the document was generated, for example.
In some implementations, graphical interface 300 can include version information area 304. For example, version information area 304 can present a list of the available versions of the document. Version information area 304 can display document version information including a date and time when each version was generated, a description of each document version and a user who caused the document version to be generated. In some implementations, as a user navigates through document versions (e.g., using up arrow key or down arrow key), the document version information corresponding to the currently displayed document version can be highlighted in version information area 304.
At step 604, a particular page or portion of a first version of the document can be presented. For example, if the document versions interface has just been invoked from a document editing application, the version of the document displayed can be the current working version of the document and the page or portion displayed can be the page or portion currently being edited or displayed in the document editing application. If the user has performed document version navigation operations within the document versions interface, then the version of the document displayed can be the version of the document that the user navigated to most recently and the page of the document displayed can be the page of the document that the user navigated to most recently.
At step 606, user input can be received. In some implementations, page navigation input can be received. For example, a user can provide input to right or left arrow keyboard keys to navigate between pages of a version of a document. In some implementations, document version navigation can be received. For example, a user can provide input to up or down arrow keyboard keys to navigate between versions of a document. Other input, such as touch input gestures, can be used to navigate between pages and/or versions of a document, as described above.
At step 608, the particular page or portion of the first document version is replaced by a corresponding page or portion of a second version of the document. In some implementations, when document version navigation input is received (e.g., up arrow key input, down arrow key input), different versions of the same page or portion can be displayed. For example, page five of a first version of the document can be replaced by page five of a second version of the document so that the user can make a visual comparison of the different versions of page five of the document. For example, a particular portion or location within a worksheet of a first version of a spreadsheet can be replaced by a corresponding portion or location within a worksheet of a second version of the spreadsheet so that the user can make a visual comparison of the different versions of the particular portion or location of the spreadsheet worksheet.
Sensors, devices, and subsystems can be coupled to the peripherals interface 706 to facilitate multiple functionalities. For example, a motion sensor 710, a light sensor 712, and a proximity sensor 714 can be coupled to the peripherals interface 706 to facilitate orientation, lighting, and proximity functions. Other sensors 716 can also be connected to the peripherals interface 706, such as a global navigation satellite system (GNSS) (e.g., GPS receiver), a temperature sensor, a biometric sensor, or other sensing device, to facilitate related functionalities.

The other input controller(s) 744 can be coupled to other input/control devices 748, such as one or more buttons, rocker switches, thumb-wheel, infrared port, USB port, and/or a pointer device such as a stylus. The one or more buttons (not shown) can include an up/down button for volume control of the speaker 728 and/or the microphone 730.
In one implementation, a pressing of the button for a first duration can disengage a lock of the touch surface 746; and a pressing of the button for a second duration that is longer than the first duration can turn power to the mobile device 100 on or off. Pressing the button for a third duration can activate a voice control, or voice command, module that enables the user to speak commands into the microphone 730 to cause the device to execute the spoken command. The user can customize a functionality of one or more of the buttons. The touch surface 746 can, for example, also be used to implement virtual or soft buttons and/or a keyboard.
In some implementations, the mobile device 100 can present recorded audio and/or video files, such as MP3, AAC, and MPEG files. In some implementations, the mobile device 100 can include the functionality of an MP3 player, such as an iPod™ The mobile device 100 can, therefore, include a 36-pin connector that is compatible with the iPod. Other input/output and control devices can also be used.
The memory interface 702 can be coupled to memory 750. The memory 750 can include high-speed random access memory and/or non-volatile memory, such as one or more magnetic disk storage devices, one or more optical storage devices, and/or flash memory (e.g., NAND, NOR). The memory 750 can store an operating system 752, such as Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks.
The operating system 752 can include instructions for handling basic system services and for performing hardware dependent tasks. In some implementations, the operating system 752 can be a kernel (e.g., UNIX kernel). In some implementations, the operating system 752 can include instructions for performing a visual comparison of document versions. For example, operating system 752 can implement the document version navigation and document page navigation features described with reference to
