RELATED APPLICATION
This application is a continuation and claims the benefit of U.S. application Ser. No. 13/929,698 filed Jun. 27, 2013, the disclosure of which is entirely incorporated herein by reference.


BACKGROUND
The present disclosure generally relates to user interfaces and, in particular, to display modes in a web browser.
Web browsers are configured to load web pages for display in a display area of a browser. In some cases multiple web pages or may be loaded at the same time using browser tabs. For example, a web browser may have multiple tabs open and each tab may contain a loaded web page. For each web browser window, one of the tabs may be an active tab and the other tabs may be hidden or non-active tabs. The web page loaded in the active tab may be shown in the display area of the browser while the web pages loaded in the hidden tabs are not shown in the display area. Instead, to view those web pages, a user may select a hidden tab to make the selected tab the active tab so that the web page loaded in the selected tab may be shown in the display area of the browser. Some browsers or web pages may enable users to select a full-screen mode or immersive mode for a web browser where the contents of the active tab may be viewed in full-screen.

DETAILED DESCRIPTION
The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The appended drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will be apparent that the subject technology may be practiced without these specific details.
A web browser may be configured to allow a user to enter an immersive mode (e.g., a full-screen mode) for the web browser. When the web browser is in the immersive mode, the content of an active browser tab, which is typically a web page, is shown in the entire area of the web browser's display area. In some cases, this may be the entire web browser window or the entire screen of one or more monitors or displays. However, when the web browser is in the immersive mode, the tabs are not visible to the user. Accordingly, the user may not be aware of or have any visual indication of the number of tabs open, the location of the tabs, which tabs are active or hidden, or any other information other than the content of the active tab.
Various aspects of the subject technology relate to systems and methods for providing one or more light bars in the display area of a web browser while the web browser is in an immersive mode. The light bars are configured to provide a persistent visual indicator of the one or more tabs without taking much space in the display area of the web browser. The persistent visual indicators may allow a user to determine how many tabs are open without taking any action such as moving a cursor to a prescribed area to show hidden tabs. Furthermore, the light bars provide visual indicators that take up less space than the browser tabs that they replace.
FIG. 1 is an illustration of an example user interface 100 showing a web browser 105, in accordance with various aspects of the subject technology. The user interface 100 may be a desktop, screen, or display provided by a device. The device may be, for example, a computer, a laptop, a tablet, a mobile phone, a mobile device, a smart television or screen, a display device, or any other machine associated with a display.
The web browser 105 may contain a number of browser tabs 110, 115, 120, and 125 that are shown in a non-display portion 135 of the web browser. The non-display portion 135 of the web browser 105 may be, for example, a tool bar, a ribbon, a border, or other portion of the web browser 105 that does not display the content of a browser tab. Each browser tab may contain content such as a web page, an image, a document, spreadsheet, a video, or any other content or media that may be loaded by a web browser 105. The browser tabs in the web browser 105 may be active or hidden.
For example, in FIG. 1, browser tab 110 is an active tab, while browser tabs 115, 120, and 125 are hidden tabs. The content contained in the active tab 110 may be shown in a display area 130 of the web browser 105 while the content loaded in the hidden tabs 115, 120, and 125 are not visible in the display area 130. If a user wishes to see the content loaded in one of the hidden tabs, the user can select the hidden tab to make the selected tab the active tab. Accordingly, the content contained in the selected tab will be shown in the display area 130.
The web browser 105 may also enable users to activate an immersive mode for the web browser in which the contents of the active tab enlarged to cover, for example, the entire web browser window 105 or the entire user interface 100. A user can activate the immersive mode by, for example, using a hot-key, activating a user interface element such as a button, typing in a command, using a gesture on a track pad, or by some other means.
FIG. 2 is an illustration of an example user interface 200 showing a web browser in an immersive mode, in accordance with various aspects of the subject technology. The user interface 200 may be a desktop, screen, or display provided by a device or, in some aspects, the user interface 200 may be the browser window. As is shown in FIG. 2, the non-display portions of the web browser and the browser tabs are not visible when the web browser is in the immersive mode. Instead, display area 205 of the web browser and the contents of the active tab are expanded in the user interface 200. Accordingly, there are no visual indications of how many tabs are open, which tabs are active or hidden, or any other information other than the content of the active tab. Furthermore, there are no interface elements visible that the user can user to select another browser tab to switch the active browser tab.
FIG. 3 is an illustration of another example user interface 300 showing a web browser in an immersive mode, in accordance with various aspects of the subject technology. As seen with FIG. 3, the non-display portions of the web browser and the browser tabs are not visible during the immersive mode. Instead, display area 305 of the web browser and the contents of the active tab are expanded in the user interface 300. However, in FIG. 3, a system, such as the web browser running on a device, may be configured to provide for the display of light bars 310, 315, 320, and 325 in the display area 305. According to some aspects, the light bars 310, 315, 320, and 325 may be displayed at an edge of the display area 305, at the top of the display area 305, or near an edge of the display area 305 (e.g., at a predetermined offset distance away from the top edge of the display area 305).
The light bars 310, 315, 320, and 325 may provide a persistent visual indicator of the browser tabs of the web browser. Each of the light bars 310, 315, 320, and 325 is associated with one of the browser tabs of the web browser. The light bars 310, 315, 320, and 325 may be smaller, thinner, or take up less space on the user interface 300 than the browser tabs which they replace. For example, the light bars 310, 315, 320, and 325 may be 5 or less pixels in width.
Accordingly, they may be less distracting to a user or obscure less of the content of the active browser tab. According to some aspects, a user may select the light bar in order to activate the associated browser tab and make that browser tab the active browser tab. This may result in the display area 305 changing to the content of the browser tab associated with the selected light bar.
According to some aspects, the light bars 310, 315, 320, and 325 may be composed of one or more colors. The colors of the light bars may be default colors (e.g., a default color, a default color for an active tab, a default color for a hidden tab, etc.), colors selected based on the content of the tab, or a combination of these. In some cases, the colors may be selected based on an image or icon associated with a browser tab. For example, the icon may be a shortcut icon, a “favicon,” a web site icon, a bookmark icon, a miniaturized image of the content of a browser tab, or any other image associated with the content of the browser tab. One or more colors for the light bar associated with the browser tab may be selected based on the dominant colors in the icon.
In some aspects, the light bars may have additional functionality. For example, each light bar may be configured to indicate states of web pages. A light bar may be configured to, for example, indicate when content (e.g., a web page) is loading, when content has finished loading, when an error has occurred, or if the tab is playing audio or video content. The light tab may indicate these stages by flashing or pulsing a particular color or combination of colors, turning a particular color, or becoming dimmer or brighter. For example, the light bar for a tab may be dimmed while the tab is loading content and become brighter when the content has finished loading. When there is an error associated with a tab, the light bar for the tab may be a default error color (e.g., bright red). When audio or video content is being played in a tab, the light bar for the tab may pulse a white light.
FIG. 4 is a block diagram illustrating an example system 400 configured to provide a light bar in a web browser during an immersive mode, in accordance with various aspects of the subject technology. The system 400 may include a display module 410, an input module 420, and a content module 430. In other aspects, however, the system may include additional modules, alternative modules, or fewer modules.
The display module 410 is configured to provide the display functions of a web browser on a computing machine or device (e.g., a laptop, a tablet, a computer, a smart television, a smart phone, a mobile device, etc.). For example, the display module 410 is configured to display the web browser in all of its various browsing modes, the browsing tabs, the content loaded in an active browsing tab, and any other displayed interface of the web browser. The display module 410 may also be configured to display one or more light bars associated with the browsing tabs when the web browser is in immersive mode.
The input module 420 is configured to receive input from various sources such as, for example, a user. Inputs that may be received may include uniform resource locators (URLs) inputted by a user, instructions to open a link received from the user or another process or system, or indications to enter or exit various browsing modes such as an immersive browsing mode.
The content module 430 may be configured to load content in a browser display area for viewing. For example, the content module 430 may communicate with various resources over a network (e.g., the Internet) in order to obtain content (e.g., images, web pages, video, audio, files, etc.) so that the content may be displayed by the display module 410. In other aspects, the content may be accessed on a local hard drive or other memory in more direct communication with the system 400.
FIG. 5 is a flow chart illustrating an example process 500 for providing a light bar in a web browser during an immersive mode, in accordance with various aspects of the subject technology. Although the process blocks of FIG. 5 are described with reference to the components of the system 400 in FIG. 4, the blocks are not limited to being performed by these components. In addition, although the blocks in process 500 are shown in a particular order, certain blocks may be executed in different orders or at the same time.
At block 505, the display module 410 may display a web browser having one or more browser tabs (e.g., an active browser tab and possibly one or more hidden browser tabs). The web browser may be displayed in a first browsing mode, such as a normal browsing mode where the browser tabs are in an area of the browser that does not display loaded content (e.g., a web page, an image, etc.) for the active browser tab. The area may be, for example, a tool bar, a ribbon, or a border of the web browser.
The input module 420 may determine whether a user indication to enter a second browsing mode, an immersive mode, has been received. The user indication may be received via a hot-key, a user interface element such as a button, using a gesture on a track pad, or through some other command or instruction. If a user indication has not been received, the browser may continue to operate in the first browsing mode.
If a user indication is received by the input module 420, the display module 410 may display the web browser in the second browsing mode (e.g., immersive mode) at block 515. When the web browser is in the immersive mode the display area of the web browser is expanded in the user interface of the web browser and contents of the active tab may appear full-screen. Furthermore, the browser tabs that are visible in the normal browsing mode are not shown in the immersive mode.
At block 520, the display module 410 may also display one or more light bars in the display area of the user interface. Each light bar displayed in the user interface may be associated with one of the browser tabs and may be displayed in a location corresponding to the browser tab. For example, the light bar displayed at the left-most position may be associated with the browser tab displayed the furthest left when the web browser was in normal browsing mode. The light bar displayed at the second to left-most position may be associated with the browser tab displayed the second to furthest left when the web browser was in normal browsing mode. The positions of the other light bars may similarly correspond to the browser tab that each light bar is associated with.
As mentioned above, the light bars displayed may be colored the same or differently. According to some aspects, the displaying of the light bars includes selecting one or more colors for each light bar and displaying the light bar in accordance to the selected color(s). In one implementation, the one or more colors for a light bar associated with a browser tab may be selected based on an image associated with the browser tab. For example, the image may be a miniaturized version of the content (e.g., the image, the web page, etc.) of the browser tab. In another example, the image may be an icon associated with the browser tab or the content of the browser tab. The icon may be a “favicon,” a web site icon, or a bookmark icon.
To select one or more colors from the image, the display module 410 may generate a prioritized list of colors used in the image and select the most used or most dominant colors in the image. According to some aspects, generating the prioritized list of colors may include a number of image processing steps such as removing background colors (e.g., whitespace or other colors that serve as a background to the icon), grouping together similar colors, determining a weighted average color for each group of similar colors, and determining the portion of the image (e.g., the number of pixels) that correspond to each group of similar colors. The group of similar colors that is responsible for the biggest portion of the image may be assigned the highest priority and the color used for that group of colors may be the average color for that group of colors. The other colors in the prioritized list of colors may be similarly determined.
In some cases each light bar may include more than one color. For example, a portion of the light bar may be a first color and the rest of the light bar may be a second color. All of the colors for the light bar may be selected based on the image associated with the browser tab or only some of the colors may be based on the image. For example, the first portion of the light bar may be a color selected based on the image while the second color may be selected based on a default color or a characteristic of the browser tab.
In one aspect, the default color may be a predefined color (e.g., a shade of grey). There may also be multiple default colors based on the characteristic of the browser tab. For example, there may be one default color for active browser tabs and another default color for hidden browser tabs. Accordingly, a light bar for an active browser tab may include the default color for the active browser tab, while a light bar for a hidden browser tab may include the default color for the hidden browser tab.
FIG. 6A and FIG. 6B are illustrations of portions of example user interfaces that include light bars, in accordance with various aspects of the subject technology. For example, in FIG. 6A, the user interface 605 includes light bars 610, 615, 620, and 625 that each include two colors or textures. Although FIG. 6A includes light bars that each contain only two colors, in other implementations, more colors or textures may also be may be used. Furthermore, the light bars included in the user interface may have a different number of colors or textures used than other light bars.
The light bars may also be placed in different locations in the user interface. For example, in FIG. 6A, the user interface 650 includes light bars 655, 660, 665, and 670 that are located at the topmost edge of the user interface 650. In other implementations, the light bars may be located at or near other edges (e.g., a right edge, a left edge, or a bottom edge). The light bars may also be arranged horizontally, vertically, or in other orientations.
