Title: Display of immersive and desktop shells

Description:
BACKGROUND 
     Users have access to computing devices that may assume a wide variety of configurations. For example, the first computing devices that were traditionally available to common users were configured as desktop personal computers. Users typically interacted with these first computing devices using a keyboard and later a mouse to view data on a monitor. 
     Computing devices continued to evolve as users desired to interact with the devices in an increasing variety of circumstances. One such example was mobile phones that evolved from basic telephone functionality to the ability to run applications. Another such example is a slate computer, which may also be referred to as a tablet. Both of these examples are configured to be held by a user during interaction and thus techniques were developed to address this configuration. 
     Because of the different configurations of the computing devices, however, a variety of different techniques may be employed for interaction. Thus, even typical users may be confronted with a wide range a different techniques, even to utilize matching functionality of the devices, which could lead to user frustration and even cause the users to forgo use of computing devices having the different configurations. 
     SUMMARY 
     Desktop as an immersive application techniques are described. In one or more implementations, an immersive environment module is configured to provide an immersive shell through which a user may interact with applications of a computing device. The immersive environment module is further configured to provide a desktop shell within the immersive shell to support additional techniques for interaction with the application of the computing device. The desktop shell, for instance, may be configured for accessibility similar to that provided to applications in the immersive shell.

     DETAILED DESCRIPTION 
     Overview 
     The diversity of computing devices with which a user interacts even in a typical day is growing rapidly. However, conventional techniques via which a user interacted with the devices were often optimized for these configurations. Thus, different techniques could be employed by different computing device configurations, even to access matching functionality. Additionally, development of new configurations could confound users due to the new ways in which a user could interact with the device, which could even result in a user forgoing interaction with unfamiliar device configurations. 
     A desktop as an immersive application is described. In one or more implementations, an operating system may support an immersive shell via which a user may interact with applications and consequently data of a computing device that implements the shell. For example, the immersive shell may be configured to consume a significant amount of a display area of a display device and limit and even forgo use of “chrome,” (e.g., representations of controls such as menu bars), support scrolling and navigation techniques that may be well suited to slate computer configurations as well as other configurations, such as a traditional desktop computer. 
     The operating system may also support a desktop shell that is configured for navigation through a hierarchical file system using windows that contain folders, icons, and so on. In this example, the desktop shell is accessible within the immersive shell similar to how other applications are accessed in the immersive shell. Thus, the functionality of the desktop shell may be made readily accessible via the immersive shell to provide a user with a variety of different techniques to navigate through applications and files of the computing device. For example, a user may interact with the immersive shell to access applications using a computing device in a configuration of a slate computer and may also access the desktop to gain access to other functionality in a traditional manner that is readily understood by the user. Further, these techniques may be utilized to efficiently manage resources of the computing device. For example, these techniques may be used to conserve resources (e.g., power, processing, and memory) in the immersive shell yet provide access to additional resources when accessing the desktop shell through the immersive shell. Further discussion of the desktop as an immersive application may be found in relation to the following sections. 
     In the following discussion, an example environment is first described that may employ the techniques described herein. Example procedures are then described which may be performed in the example environment as well as other environments. Consequently, performance of the example procedures is not limited to the example environment and the example environment is not limited to performance of the example procedures. 
     Example Environment 
       FIG. 1  is an illustration of an environment  100  in an example implementation that is operable to employ techniques described herein. The illustrated environment  100  includes a computing device  102  having a processing system  104  and a computer-readable storage medium that is illustrated as a memory  106  although other confirmations are also contemplated as further described below. 
     The computing device  102  may be configured in a variety of ways. For example, a computing device may be configured as a computer that is capable of communicating over a network, such as a desktop computer, a mobile station, an entertainment appliance, a set-top box communicatively coupled to a display device, a wireless phone, a game console, and so forth. Thus, the computing device  102  may range from full resource devices with substantial memory and processor resources (e.g., personal computers, game consoles) to a low-resource device with limited memory and/or processing resources (e.g., traditional set-top boxes, hand-held game consoles). Additionally, although a single computing device  102  is shown, the computing device  102  may be representative of a plurality of different devices, such as multiple servers utilized by a business to perform operations such as by a web service, a remote control and set-top box combination, an image capture device and a game console configured to capture gestures, and so on. 
     The computing device  102  is further illustrated as including an operating system  108 . The operating system  108  is configured to abstract underlying functionality of the computing device  102  to applications  110  that are executable on the computing device  102 . For example, the operating system  108  may abstract the processing system  104 , memory  106 , network, and/or display device  112  functionality of the computing device  102  such that the applications  110  may be written without knowing “how” this underlying functionality is implemented. The application  110 , for instance, may provide data to the operating system  108  to be rendered and displayed by the display device  112  without understanding how this rendering will be performed. The operating system  108  may also represent a variety of other functionality, such as to manage a file system and user interface that is navigable by a user of the computing device  102 . 
     The operating system  108  is also illustrated as including an immersive environment module  114  which is representative of functionality of the computing device  102  to provide an immersive shell  116  via which a user may interact with the applications  110  and other data of the computing device  102 , both local to the device as well as remotely via a network. The immersive shell  116  is configured to accept inputs to interact with the operating system  108  and applications  110  of the computing device  102  to access functionality of the computing device  102 , such as the abstracted functionality described above. The immersive shell  116  may also be configured to support a desktop shell  118  as further described below. 
     The immersive shell  116  may be configured to support interaction with the applications  110  with little to no window frame. Additionally, the immersive shell  116  may support interaction with the applications  110  without requiring the user to manage a corresponding window frame&#39;s layout, primacy of the window with respect to other windows (e.g., whether a window is active, in front of behind other windows, an order of the windows, and so on). Although illustrated as part of the operating system  108 , the immersive environment module  114  may be implemented in a variety of other ways, such as a stand-alone module, remotely via a network, and so forth. 
     In one or more implementations, the immersive shell  116  of the operating system  108  is configured such that it is not closeable or capable of being uninstalled apart from the operating system  108 . Additionally, the immersive shell  116  may be configured to consume a significant portion of an available display area of the display device  112 . A user may interact with the immersive shell  116  in a variety of ways, such as via a cursor control device, using one or more gestures, using speech recognition, capture using one or more depth-sensing cameras, and so on. 
     Thus, the immersive environment module  114  may manage the immersive shell  116  in which content of applications  110  may be presented and the presentation may be performed without requiring a user to manage size, location, primacy, and so on of windows used to display the content of the applications  110 . 
     For example, as shown on a user interface displayed by the display device  112 , a user interface is shown that is configured to display data  122 ,  124  from two applications in a “snapped” configuration. In this example, both of the applications that correspond to the data are enable to actively execute by the computing device  102  while execution is suspended for other of the applications  110  that do not currently display data. A gutter  126  is disposed between the displays of the data  122 ,  124  that may be moveable to change an amount of display area consumed by applications on the display device  112 , respectively. 
     The immersive shell  116  may support a wide variety of functionality to provide an immersive experience for a user to access the applications  110 . In the following discussion, this functionality is discussed in relation to leveraging these techniques to enable interaction with a desktop shell  118 . It should be readily apparent, however, that these techniques may be employed for managing interaction with the applications  110  themselves without departing from the spirit and scope thereof. 
     As illustrated, the immersive shell  104  includes a desktop shell  118 . The desktop shell  118  is representative of another configuration of a user interface output by the operating system  108  when in this example is to interact with the applications  110  and other data. For example, the desktop shell  118  may be configured to present applications and corresponding data through windows having frames. These frames may provide controls through which a user may interact with an application as well as controls enabling a user to move and size the window. The desktop shell  118  may also support techniques to navigate through a hierarchical file structure through the use of folders and represent the data and applications through use of icons. In one or more implementations, the desktop shell  118  may also be utilized to access application s  110  that are configured specifically for interaction via the desktop shell  118  and not configured for access via the immersive shell  116 , although other implementation are also contemplated. 
     In one or more of the techniques described herein, the immersive shell  104  provides access to the desktop shell  118  as if the desktop shell  118  was another application that was executed on the computing device  102 . In this way, a user may utilize the functionality of the immersive shell  116  yet still access the desktop shell  118  for more traditional functionality. Examples of implementation of the desktop as an immersive application within the immersive shell may be found in relation to the following figures. 
     Generally, any of the functions described herein can be implemented using software, firmware, hardware (e.g., fixed logic circuitry), or a combination of these implementations. The terms “module,” “functionality,” and “engine” as used herein generally represent software, firmware, hardware, or a combination thereof. In the case of a software implementation, the module, functionality, or engine represents program code that performs specified tasks when executed on a processor (e.g., CPU or CPUs). The program code can be stored in one or more computer readable memory devices. The features of the techniques described below are platform-independent, meaning that the techniques may be implemented on a variety of commercial computing platforms having a variety of processors. 
     For example, the computing device  102  may also include an entity (e.g., software) that causes hardware of the computing device  102  to perform operations, e.g., processors, functional blocks, and so on. For example, the computing device  102  may include a computer-readable medium that may be configured to maintain instructions that cause the computing device, and more particularly hardware of the computing device  102  to perform operations. Thus, the instructions function to configure the hardware to perform the operations and in this way result in transformation of the hardware to perform functions. The instructions may be provided by the computer-readable medium to the computing device  102  through a variety of different configurations. 
     One such configuration of a computer-readable medium is signal bearing medium and thus is configured to transmit the instructions (e.g., as a carrier wave) to the hardware of the computing device, such as via a network. The computer-readable medium may also be configured as a computer-readable storage medium and thus is not a signal bearing medium. Examples of a computer-readable storage medium include a random-access memory (RAM), read-only memory (ROM), an optical disc, flash memory, hard disk memory, and other memory devices that may use magnetic, optical, and other techniques to store instructions and other data. 
       FIG. 2  illustrates a system  200  in an example implementation of the computing device  102  of  FIG. 1  as supporting launching of applications into an immersive environment through selection of representations of the applications configured as tiles. The system  200  is illustrated as including first and second stages  202 ,  204 . At the first stage  202 , the computing device  102  is illustrated as outputting a start screen of the immersive shell  116 . The start screen includes a plurality of tiles that represent applications that are selectable for execution by the computing device  102 . A variety of other representations are also contemplated without departing from the spirit and scope thereof as previously described. 
     Selection of the tiles may be accomplished in a variety of ways. For example, a user may utilize a cursor control device, such as a mouse or track pad, to navigate a cursor to be displayed “over” a tile to be selected and “click” the tile to indicate the selection. As illustrated at the first stage  202 , for instance, a cursor is shown as disposed over a tile of a social network app. In another example, gestures may be supported by the computing device  102 , such as by tapping a desired representation to launch a corresponding application. 
     Responsive to the selection, the corresponding application  110  may be launched for execution by the computing device  102 . An example of this is illustrated at the second stage  204  in  FIG. 2  in which the social network application is launched into the immersive shell  116 . The social network application is illustrated as providing a user interface  206  that consumes approximately an entirety of a display area of the display device  112 . Additionally, the user interface  206  as illustrated does not include a window or “chrome” that is displayed along with the data of the application. 
     This technique may be repeated to launch a plurality of applications  110  for execution by the computing device  102 . For example, a user may return to the start screen illustrated in the first stage  202  and select additional applications for execution, such as through selecting a “start” selection in a menu  804  of commands (e.g., “charms”) as illustrated and further described in relation to  FIG. 8 . Responsive to each selection, additional user interfaces may be output that substantially consume the available display area of the display device. 
     A user may then navigate through the applications that have been selected for execution in a variety of ways. For example, a user may interact with a left edge  208  of the display device to cause the display of the social network application to be replaced with a display that corresponds to another application that was launched by the user. 
     As before, this interaction may be performed in a variety of ways, such as through maneuvering a cursor proximal to the left edge  208 , a “swipe” gesture involving the left edge  208 , and so on. This replacement may be performed non-modally by automatically cycling through the applications, modally through output of a menu having representations of the selected applications  110 , and so on. Although interaction with the left edge  208  is described for navigation through the applications  110 , it should be readily apparent that different edges may be utilized as well as different navigation techniques without departing from the spirit and scope thereof. 
     Other functionality may also be supported in the immersive shell  116 . For example, interaction with the top or bottom edges  210 ,  212  may cause output of a menu (e.g., through a gesture and/or cursor control device) that is customized for an application  110  that is currently being displayed in the immersive shell  116 . In other words, the menu may include commands that are specified by the application  110  for inclusion in the menu, e.g., that may involve interaction with the application as well as other functionality. 
     The immersive shell  116  may also support “snapping” of user interfaces of applications to support display of data from a plurality of the applications  110 . As shown and described previously in relation to  FIG. 1 , for instance, data from weather and social network applications may be displayed concurrently on the display device  112 . This data may be separated by a gutter  126  that is configured to adjust an amount of display area of the display device that is consumed by the respective applications. A variety of other immersive shell  116  functionality may also be supported by the immersive environment module  114 , further examples of which may be found in relation to the following figures. 
     As described previously, the immersive environment module  114  may also support access to a desktop shell  118  as if the desktop shell  118  were an application of the computing device  102 . An example of this is illustrated as a tile  214  that is representative of the desktop shell  118 . The tile  214  in this instance is configured to display one or more windows that are saved as part of the state in the desktop shell  118 . In other words, the tile  214  represents at least part of a user interface that would be output upon selection of the tile  214 . 
     Additionally, the tile  214  may be configured to support selection of a view of the desktop itself as well as particular windows included in the representation. For example, a user may select an area within the tile  214  that is outside of the windows in the tiles to cause output of the desktop, such as through a cursor control device, gesture, and so on. Additionally, a user may select a particular window within the tile  214  to navigate directly to that window in the desktop shell  118 , again which may be performed using a cursor control device, gesture, and so on. Thus, the desktop shell  118  may be represented in a manner that mimics representation of other applications in the start screen. Further, the tile  214  may be utilized to navigate directly to applications that are accessible within the desktop shell  118 . Although not shown, launching of the desktop shell  118  may include output of a “splash” screen similar to a splash screen involved in the launching of an application  110 . 
     Other tiles may also be included to navigate directly to applications  110  and/or particular data that is to be processed in conjunction with the applications  110 . An example of this is illustrated by a tile  216  that corresponds to a particular spreadsheet to be output by a spreadsheet application. By selecting this tile  216 , the spreadsheet application may be launched within a desktop shell  118  to include particular data, such as an office expense spreadsheet. Other examples are also contemplated, such as to navigate to particular files for processing by a word processing application, presentation application, photo editing application, and so on. 
       FIG. 3  depicts an example implementation  300  of the immersive shell  116  as outputting data from a social network application and providing access to the desktop shell  118  as an immersive application. In this example, a user interface displayed by the display device  112  includes a primary region  302  and a secondary region  304  that are illustrated as rendering data from a social network application and the desktop shell  118 , respectively. 
     The primary and secondary regions  302 ,  304  are illustrated as being separated by a gutter  306 . The gutter  306  may support interaction such that a user may move the gutter  306  to change an amount of display area consumed by the primary and secondary regions  302 ,  304 , respectively. In one or more embodiments, the primary region  302  is configured to consume a larger area of the display device  112  than the secondary region and thus, the primary region may be implemented on any side of the display device  112 . 
     The secondary region  304  may be considered as “docking” or “snapping” a display of data from a corresponding application  110  yet making that display available for view. The use of the primary and secondary regions  302 ,  304  may also be utilized to support navigation as further described in relation to  FIG. 5 . 
     In the illustrated implementation  300  of  FIG. 3 , a finger of a user&#39;s hand  308  is depicted as selecting a window corresponding to an email application in the representation of the desktop shell  118  in the secondary region  304 . This may be utilized to programmatically “unsnap” the desktop shell  118  from the secondary region  304  for placement in the primary region  302 . 
     Like the tile  214  that was described previously for the desktop shell  118 , the secondary region  304  may also support a range of navigation techniques. For example, a user may select an area within the secondary region  304  but outside of the windows in the region to cause output of the desktop, such as through a cursor control device, gesture, and so on. Additionally, a user may select a particular window within the secondary region  304  to navigate directly to that window in the desktop shell  118 , such as by making that window the “primary” window that is displayed “on top” of other windows in the primary region  302  by the desktop shell  118 . Thus, secondary region  304  may be utilized to navigate directly to applications that are accessible within the desktop shell  118 . 
     As illustrated in  FIG. 3 , for instance, a finger of the user&#39;s hand  308  is illustrated as selecting a window in the secondary region  304  of the immersive shell  116 . Responsive to this selection, the immersive environment module  114  may cause the desktop shell  118  to be displayed in a primary region  302  of the user interface. 
     Additionally, the immersive environment module  114  may display the window that was selected in the secondary region  304  as ready for user interaction. For example, the window may be selected and given focus and thus inputs received by the computing device  102  are directed to an application  110  that corresponds to the selected window. An example of a result of a selection of the email window in the secondary region  304  is illustrated in relation to the following figure. 
       FIG. 4  depicts an example implementation  400  in which a result of selection of the desktop shell  118  in an immersive environment of  FIG. 3  from a secondary region  304  for display in a primary region  302  is shown. In the illustrated example, the desktop shell  118  is displayed in the primary region of the user interface on the display device  112 . Additionally, data rendered from an application that was originally positioned in the primary region  302  of the user interface of  FIG. 3  is illustrated as moved to the secondary region  304 . Thus, in this example content in the respective portions is “switched” responsive to the selection of  FIG. 3 . 
     The example implementation  400  is also illustrated as outputting a notification  402 . The notification  402  may include a wide variety of information. For example, when the desktop shell  118  is displayed in the user interface the notification may include information pertaining to execution of applications within the desktop shell  118 . An instance of this is illustrated in  FIG. 4  as indicating receipt of an email message that describes a sender of the message, e.g., “Sara,” and a subject line of the message, e.g., “Ellie&#39;s B-day.” Thus, the immersive environment module may surface notifications in the desktop shell  118  that pertain to applications that are executed within the shell. 
     Other notification techniques are also contemplated. For example, the notification  402  may describe execution of other applications that are not currently displayed in the immersive shell  116 . For instance, a notification may be displayed that pertains to an application that “resides” in the secondary region  304 , is executed “off screen,” and so on. In another example, the notification  402  may describe execution of applications within the desktop shell  118  even if the desktop shell  118  is not currently being displayed within the immersive shell  116  on the display device  112 . A variety of other examples are also contemplated. 
       FIG. 5  depicts an example implementation  500  in which a user interface of  FIG. 4  is scrolled to navigate in an immersive shell from the desktop shell  118  to an application. In this example, a finger of a user&#39;s hand  502  is illustrated as being placed proximal to the display device  112  over the primary region  302 . The finger of the user&#39;s hand  502  is then illustrated (through using an arrow) as being slid toward the left edge  208  of the display device  112 . 
     In an implementation, this gesture may be recognized by the immersive environment module  114  as indicating that the display of data from the desktop shell  118  is to be placed in the secondary region  304 . The placement of the data from the desktop shell  118  in the secondary region  304  may thus replace the data from the application that was previously displayed in that portion, e.g., the data from the social network app as illustrated. This gesture may be continued to navigate through applications that have been selected for execution by a user, e.g., selection of the tiles in  FIG. 2 . 
     Thus, the primary and secondary regions  302 ,  304  of the user interface may be leveraged to navigate through the applications  110  (including the desktop shell  118 ) to locate a desired application  110  or desktop shell  118  of interest. Although a gesture was described, this operation may be initiated by a variety of inputs, such as a “click-and-drag” from the primary region  302  toward the secondary region  304 , an input that describes movement from the primary region  302  over the gutter  306 , and so forth. Again, although movement toward the left edge  208  of the display device  102  was described, it should be readily apparent that a wide variety of edges of the display device, gestures, commands, cursor movements, and other inputs may be utilized to initiate the features described above. 
       FIG. 6  depicts another example implementation  600  in which a technique is employed to navigate between applications and a desktop shell  118  in an immersive shell. In this example, a finger of a user&#39;s hand  602  is illustrated as being placed proximal to a top edge  210  of the display device  112  in the primary region  302  of the user interface. The immersive environment module  114  may recognize a gesture once the movement has crossed a threshold, e.g., approximately half-way down a display area of the display device  112 . 
     In response to recognizing this gesture, the immersive environment module  114  may generate a reduced display  604  of the data from the desktop shell  118 . Further, the immersive environment module  114  may cause this reduced display to follow subsequent movement of the finger of the user&#39;s hand  602 . Thus, this may indicate to the user that the data from the desktop shell  118  in the reduced display may be repositioned as desired as a secondary region  304  in the user interface. 
     For example, as illustrated using the arrows an initial part of the gesture may be used to cause the reduced display  604 , which is illustrated through use of the relatively long downward arrow. Subsequent movement may then indicate to which edge of the display device  112  the data from the desktop shell  118  is to be “snapped,” which in this instance is illustrated as an arrow pointing toward a right edge  606  of the display device  112 . Once within a predefined distance, the immersive environment module  114  may cause the display of data from the desktop shell  118  to “snap” toward the corresponding edge using an animation, a result of which is shown in the following figure. 
       FIG. 7  depicts another example implementation  700  in which a result of the technique of  FIG. 6  is shown to navigate between applications  110  and a desktop shell  118  in an immersive shell  116 . In this example, a display of data from the desktop shell  118  has been “snapped” to the right edge  606  of the display device  112 . This has caused the user interface to be reconfigured such that the data from the social network application is displayed in the primary region  302  of the user interface that is now positioned on the left side of the display device  112 . The display of data from the desktop shell  118  is now made a part of the secondary region  304  of the user interface. Thus, this gesture may be used to navigate and/or reposition displays of data from respective applications  110  and for the desktop shell  118 . Again, it should be readily apparent that a wide variety of edges of the display device, gestures, commands, cursor movements, and other inputs may be utilized to initiate the features described above. 
       FIG. 8  depicts an example implementation  800  in which a menu is output having commands that may be implemented to a corresponding selection in the immersive shell  116  as a whole. In this example, a finger of a user&#39;s hand  802  is illustrated as being placed proximal to and moved away from the right edge  606  of the display device  112 . This input may be detected (e.g., using touchscreen functionality, motion sensors, cameras, and so on) as a gesture to output a “charm” menu  804 . 
     The menu  804  in this example includes representation of commands that may be initiated from both the applications  110  and/or the desktop shell  118  in the immersive shell  116 . Examples of such commands are illustrated as including “search,” “share,” “start,” “connect,” and “settings.” For example, the start representation may be selectable to navigate back to the start screen of  FIG. 2 . Thus, a user may select a tile from the start screen in  FIG. 2 , cause data from an application  110  represented by the tile to be output in the user interface, cause output of the menu  804  using a gesture to select the start command, which may cause output of the start screen of  FIG. 2  again so that the user may select another application for display in the immersive shell  116 . 
     In one or more implementations, the represented commands are applied to whatever is displayed in the corresponding portion (e.g., primary region  302 ). Thus, in the illustrated example selection of the “settings” representation may cause output of a menu that relates to settings of the desktop shell  118 . A variety of other examples are also contemplated, such as through selection of “share” to communicate a screenshot of the desktop shell  118 , “connect” to print, play to, or send the desktop shell  118 , “search” to initiate search functionality (e.g., to search the desktop shell  118  and/or the internet), and so forth. Although a gesture involving the right edge  606  of the display device was described in this example, it should be readily apparent that a wide variety of edges of the display device, gestures, commands, cursor movements, and other inputs may be utilized to initiate the features described above. 
     In one or more implementations, the desktop shell is “aware” of its size in the immersive shell  116  and reacts accordingly, just like immersive applications are aware of their size and react. For example, when the desktop shell  118  is displayed in a secondary region as further described below, it may change its layout and functionality to accommodate the smaller size, which can also be performed by applications that execute within the immersive shell  116 . Likewise, when there are two applications onscreen and the desktop shell  118  is in the primary region of the immersive shell  116 , the layout may also be changed by the desktop shell  116 . 
     As another example, selecting a maximize button on a window in the desktop shell  118  does not cause that window to try to fill up a full screen of the display device; rather, the desktop shell  118  may “understand” that it has a smaller space to work in, and so the maximized app “fills up” the space allotted to the desktop shell  118  within the primary region. In a further example of the “snap” functionality, where data of an application or desktop shell is dragged to the edges of a screen to resize it to a primary or secondary region. If the desktop shell  118  is currently displayed with data from an application in the immersive shell  116 , when the desktop shell  118  is dragged to the boundary between the desktop shell  118  and the application, the desktop shell  118  automatically resizes (even though the cursor is not at the edge of the screen) because desktop shell  118  is aware that the cursor had been dragged to the boundary of the desktop shell  118 . 
     In one or more implementations, the immersive shell  116  may be configured such that applications or the desktop shell  118  that are executed within the immersive shell  116  do not interfere with each other. For instance, if there are two applications onscreen in the immersive shell  116  (but outside the desktop shell  118 ), then the applications  110  or desktop shell  118  cannot create UI on top of each other and thus are “sandboxed” to their own space on the display device. Thus, the desktop shell  118  is also sandboxed like other applications in the immersive shell  116 . A variety of other examples are also contemplated, further discussion of which may be found in relation to the following procedures. 
     Example Procedures 
     The following discussion describes immersive application techniques that may be implemented utilizing the previously described systems and devices. Aspects of each of the procedures may be implemented in hardware, firmware, or software, or a combination thereof. The procedures are shown as a set of blocks that specify operations performed by one or more devices and are not necessarily limited to the orders shown for performing the operations by the respective blocks. In portions of the following discussion, reference will be made to the environment  100  of  FIG. 1 , the system  200  of  FIG. 2 , and example embodiments of  FIGS. 3-8 , respectively. 
       FIG. 9  depicts a procedure  900  in an example implementation in which a desktop shell is displayed simultaneously within an immersive shell. An immersive shell is displayed of an operating system that is configured to support access to applications using one or more techniques (block  902 ). The desktop shell is displayed simultaneously within the immersive shell, the desktop shell being displayed and also accessible using the one or more techniques to support access to the applications (block  904 ). 
     For example, the techniques may be configured to treat the desktop shell  118  as an application within the immersive shell  116 . These techniques may involve how the desktop shell  118  is display along with the applications  110  in the immersive shell  116 , how the desktop shell  118  is accessed within the immersive shell  116  (e.g., navigation between the entities), and so on. As shown in  FIGS. 3 and 4 , for instance, a display of data from the desktop shell  118  may shown along with a display of data received from an application in the immersive shell  116 . 
     As previously described, the desktop shell  118  may provide a variety of different functionality. The display of the desktop shell  118 , for instance, may include a display of a plurality of windows that correspond to a plurality of applications that are executable within the desktop shell as shown. The desktop shell  118  may also include a plurality of representations configured as icons of applications executable within the desktop shell and at least one representation of a folder to support a hierarchical file structure of the computing device  102 . 
     Further, the functionality provided within the desktop shell  118  may differ from the immersive shell  116  such that a user may be exposed to a variety of techniques to interact with the computing device  102 . For instance, the desktop shell may employ one or more windows and the immersive shell, absent the desktop shell, is not so configured. In another instance, the desktop shell is configured to employ chrome and a taskbar and the immersive shell, outside of the desktop shell, is not so configured. In a further instance, the desktop shell is configured to support an indication of priority for interaction between the applications using display of depth, e.g., layered windows. In this way, data from one application appears to be displayed over at least a portion of data from another application and the immersive shell, outside of the desktop shell, is not so configured. 
     The desktop shell may also be used to display a notification in the desktop shell as part of a window that corresponds to an application that originated the notification by changing a display characteristic of the window (block  906 ). As shown in  FIG. 3 , for instance, a window may be displayed that corresponds to an email application. In order to output a notification, such as to indicate that a new message has been received, display characteristics of the window itself may be changed, such as to “flash.” In this example the desktop shell  118  is docked to an edge of the user interface yet still provides notifications. Thus, if a window becomes “needy” while the desktop shell  118  is docked, the needy state may be indicated in the docked desktop shell using the change in display characteristics, such as those employed by taskbars. In one or more implementations, if the desktop shell  118  is off screen when the window became needy, the desktop shell  118  may be automatically scrolled into view to notify a user. In this example, the change to the display characteristic involves a frame of the window and not content within the window, although other implementation are also contemplated. 
       FIG. 10  depicts a procedure  1000  in an example implementation in which navigation is performed through an immersive shell to navigate between applications and a desktop shell. An input is recognized as specifying navigation to be performed through an immersive shell output at least in part through execution of an operating system by a computing device, the immersive shell configured to provide matching techniques to access both an application and a desktop shell (block  1002 ). A variety of different inputs may be recognized, such as gestures, inputs received from a cursor control device, and so on. One such input may involve “switching” between primary and secondary regions as described in  FIGS. 3 and 4 . Another such input may involve repositioning as described in relation to  FIGS. 6 and 7 . 
     Responsive to the recognition of the input, display of the immersive shell may be navigated that includes a display of the application and a display of the desktop shell (block  1004 ). The display in the immersive shell  116 , for instance, may be scrolled horizontally to navigate between the applications  110  and the desktop shell  118 , may involve a “top edge” gesture, use of the “snapping” techniques, and so on as previously described. 
       FIG. 11  depicts a procedure  1100  in an example implementation in which a start screen of an immersive shell is displayed that includes a tile representing an application and a tile representing a desktop shell. A start screen is displayed of an immersive shell including a first tile that is representative of an application and that is selectable to launch execution of the application and a second tile that is representative of a desktop shell that is selectable to launch execution of the desktop shell (block  1102 ). As shown in  FIG. 2 , for instance, a start screen of an immersive shell may include tiles that represent applications. Selection of the tiles may cause a corresponding application to be launched. The immersive environment module  114  may also treat the desktop shell  118  like an application as previously described and thus output a tile  214  that is representative of the desktop shell  118 . As shown, the tile  214  may include a “view” of the desktop shell  118  as it would appear if launched, such as to show windows of applications that are to be executed within the desktop shell  118 . 
     Responsive to receipt of an input that indicates selection of the second tile, execution of the desktop shell is launched within the immersive shell (block  1104 ). The desktop shell  118 , for instance, may be launched and displayed in a primary region  302  of a user interface as shown in  FIG. 4 , may consume an approximate entirety of a display area of the display device like the application in the second stage  204  of  FIG. 2 , and so forth. 
       FIG. 12  depicts a procedure  1200  in an example implementation in which an immersive shell includes a primary region, a secondary region, and is configured to display and move data generated from the desktop shell in either portion. An immersive shell is displayed including a simultaneous display of a primary region and a secondary region, the primary region including data obtained through execution of an application and the secondary region including data describing a desktop shell (block  1202 ). As shown in FIG.  FIG. 3 , for instance, data from a social network application is displayed in a primary region  302  and data from the desktop shell  118  is displayed in the secondary region  304 . 
     An input as indicating that the data describing the desktop shell is to be positioned in the primary region (block  1204 ). A gesture, for instance, may be recognized as dragging the desktop shell to the primary region  302  of the immersive shell  116 . In another instance, a “click-and-drag” command may be received using a mouse. A variety of other instances are also contemplated. 
     Responsive to the recognition, the data is displayed that describes the desktop shell in the primary region of the immersive shell (block  1206 ). Additionally, the data that was previously described in the primary region may be switched to the secondary region, may be scrolled off screen to support navigation through the applications and desktop shell in the immersive shell  116 , and so forth. 
       FIG. 13  depicts a procedure  1300  in an example implementation in which execution of a desktop shell is launched within an immersive shell. An input is received that was provided through interaction with a primary shell of an operating system to initiate a launch of a desktop shell of the operating system (block  1302 ). For example, the input may involve selection in a start screen of  FIG. 2 , selection of a second portion  304  of  FIG. 3 , scrolling through a display of applications  110  and the desktop shell  118  horizontally through gestures and/or a cursor control device, and so forth. 
     Responsive to receipt of the input, execution of the desktop shell is launched (block  1304 ) and data of the execution of the desktop shell is displayed within the primary shell of the operating system (block  1306 ). For the tile example of  FIG. 2 , the execution may be launched upon selection of the tile  214  and thus execution of the desktop shell  118  may be suspended beforehand, which may be utilized to conserve resources (e.g., battery, processing, etc.) of the computing device  102 . Likewise for the scrolling example, execution of the applications  110  and the desktop shell  118  may be suspended when those entities are off screen. Another embodiment is also contemplated in which execution of the applications  110  but not the desktop shell  118  is suspended when off screen. This data may then be displayed within the primary region  302  of the immersive shell  116  for user interaction, such as to allow a user to reposition windows and interact with application  110  that are executed within the desktop shell  118 . 
       FIG. 14  depicts a procedure  1400  in an example implementation in which notifications from a first shell are displayed in a second shell. A notification is received from an application executed in a first shell of an operating system of a computing device (block  1402 ). The notification is then displayed within a second shell of the operating system of the computing device (block  1404 ). 
     An application, for instance, may be executed within the desktop shell  118  of the operating system  108 . The notification may include a variety of different data, such as data that is typically found in a “toast” notification in a computing device, a pop-up window, and so on. In this instance, the application may be executed within the desktop shell  118  “off screen,” may be executed when the desktop shell  118  is “snapped” and “docked” to a secondary region of the immersive shell  116 , and so forth. 
     Data from the application may then be displayed in the immersive shell  116  in a variety of ways. For example, the notification may be displayed as a “toast” (e.g., a pop-up that appears for a predefined amount of time), involve an audio output, and so on. In this way, the notification may be used to keep a user aware of “what is going on” in another shell of the operating system. 
       FIG. 15  depicts a procedure  1500  in an example implementation in which a menu of commands is displayed that are applicable to applications and the desktop shell as a whole. An immersive shell is displayed that is configured to support access to applications and a desktop shell simultaneously within the immersive shell, the desktop shell being treated for display and access purposes as one of the applications within the immersive shell (block  1502 ). A menu is displayed by the immersive shell including a plurality of commands that are performable on a corresponding said desktop shell or application as a whole (block  1504 ). 
     As previously described in relation to  FIG. 8 , a menu  804  may include representation of commands that may be initiated from both the applications  110  and/or the desktop shell  118  in the immersive shell  116 . Examples of such commands are illustrated as including “search,” “share,” “start,” “connect,” and “settings.” 
     The represented commands may be applied to whatever is displayed in the corresponding portion, which is the primary region  302  in the illustrated example of  FIG. 8 . Thus, selection of the “settings” representation may cause output of a menu that relates to settings of the desktop shell  118 . A variety of other examples are also contemplated, such as through selection of “share” to communicate a screenshot of the desktop shell  118 , “connect” to print, play to, or send the desktop shell  118 , “search” to initiate search functionality (e.g., to search the desktop shell  118  and/or the internet), and so forth. A variety of other examples are also contemplated without departing from the spirit and scope thereof. 
     Example System and Device 
       FIG. 16  illustrates an example system  1600  that includes the computing device  102  as described with reference to  FIG. 1 . The example system  1600  enables ubiquitous environments for a seamless user experience when running applications on a personal computer (PC), a television device, and/or a mobile device. Services and applications run substantially similar in all three environments for a common user experience when transitioning from one device to the next while utilizing an application, playing a video game, watching a video, and so on. 
     In the example system  1600 , multiple devices are interconnected through a central computing device. The central computing device may be local to the multiple devices or may be located remotely from the multiple devices. In one embodiment, the central computing device may be a cloud of one or more server computers that are connected to the multiple devices through a network, the Internet, or other data communication link. In one embodiment, this interconnection architecture enables functionality to be delivered across multiple devices to provide a common and seamless experience to a user of the multiple devices. Each of the multiple devices may have different physical requirements and capabilities, and the central computing device uses a platform to enable the delivery of an experience to the device that is both tailored to the device and yet common to all devices. In one embodiment, a class of target devices is created and experiences are tailored to the generic class of devices. A class of devices may be defined by physical features, types of usage, or other common characteristics of the devices. 
     In various implementations, the computing device  102  may assume a variety of different configurations, such as for computer  1602 , mobile  1604 , and television  1606  uses. Each of these configurations includes devices that may have generally different constructs and capabilities, and thus the computing device  102  may be configured according to one or more of the different device classes. For instance, the computing device  102  may be implemented as the computer  1602  class of a device that includes a personal computer, desktop computer, a multi-screen computer, laptop computer, netbook, and so on. 
     The computing device  102  may also be implemented as the mobile  1602  class of device that includes mobile devices, such as a mobile phone, portable music player, portable gaming device, a tablet computer, a multi-screen computer, and so on. The computing device  102  may also be implemented as the television  1606  class of device that includes devices having or connected to generally larger screens in casual viewing environments. These devices include televisions, set-top boxes, gaming consoles, and so on. The techniques described herein may be supported by these various configurations of the computing device  102  and are not limited to the specific examples the techniques described herein. Thus, the computing device  102  is illustrated as including an immersive environment module  114  that may implement the techniques described herein. 
     The cloud  1608  includes and/or is representative of a platform  1610  for content services  1612 . The platform  1610  abstracts underlying functionality of hardware (e.g., servers) and software resources of the cloud  1608 . The content services  1612  may include applications and/or data that can be utilized while computer processing is executed on servers that are remote from the computing device  102 . Content services  1612  can be provided as a service over the Internet and/or through a subscriber network, such as a cellular or Wi-Fi network. 
     The platform  1610  may abstract resources and functions to connect the computing device  102  with other computing devices. The platform  1610  may also serve to abstract scaling of resources to provide a corresponding level of scale to encountered demand for the content services  1612  that are implemented via the platform  1610 . Accordingly, in an interconnected device embodiment, implementation of functionality described herein may be distributed throughout the system  1600 . For example, the functionality may be implemented in part on the computing device  102  as well as via the platform  1610  that abstracts the functionality of the cloud  1608 . In other words, the platform  1610  may be utilized to implement all or a part of the functionality of the immersive environment module  114 , e.g., this functionality may be distributed between the platform  1610  and the computing device  102   
       FIG. 17  illustrates various components of an example device  1700  that can be implemented as any type of computing device as described with reference to  FIGS. 1, 2, and 16  to implement embodiments of the techniques described herein. Device  1700  includes communication devices  1702  that enable wired and/or wireless communication of device data  1704  (e.g., received data, data that is being received, data scheduled for broadcast, data packets of the data, etc.). The device data  1704  or other device content can include configuration settings of the device, media content stored on the device, and/or information associated with a user of the device. Media content stored on device  1700  can include any type of audio, video, and/or image data. Device  1700  includes one or more data inputs  1706  via which any type of data, media content, and/or inputs can be received, such as user-selectable inputs, messages, music, television media content, recorded video content, and any other type of audio, video, and/or image data received from any content and/or data source. 
     Device  1700  also includes communication interfaces  1708  that can be implemented as any one or more of a serial and/or parallel interface, a wireless interface, any type of network interface, a modem, and as any other type of communication interface. The communication interfaces  1708  provide a connection and/or communication links between device  1700  and a communication network by which other electronic, computing, and communication devices communicate data with device  1700 . 
     Device  1700  includes one or more processors  1710  (e.g., any of microprocessors, controllers, and the like) which process various computer-executable instructions to control the operation of device  1700  and to implement embodiments of the techniques described herein. Alternatively or in addition, device  1700  can be implemented with any one or combination of hardware, firmware, or fixed logic circuitry that is implemented in connection with processing and control circuits which are generally identified at  1712 . Although not shown, device  1700  can include a system bus or data transfer system that couples the various components within the device. A system bus can include any one or combination of different bus structures, such as a memory bus or memory controller, a peripheral bus, a universal serial bus, and/or a processor or local bus that utilizes any of a variety of bus architectures. 
     Device  1700  also includes computer-readable media  1714 , such as one or more memory components, examples of which include random access memory (RAM), non-volatile memory (e.g., any one or more of a read-only memory (ROM), flash memory, EPROM, EEPROM, etc.), and a disk storage device. A disk storage device may be implemented as any type of magnetic or optical storage device, such as a hard disk drive, a recordable and/or rewriteable compact disc (CD), any type of a digital versatile disc (DVD), and the like. Device  1700  can also include a mass storage media device  1716 . 
     Computer-readable media  1714  provides data storage mechanisms to store the device data  1704 , as well as various device applications  1718  and any other types of information and/or data related to operational aspects of device  1700 . For example, an operating system  1720  can be maintained as a computer application with the computer-readable media  1714  and executed on processors  1710 . The device applications  1718  can include a device manager (e.g., a control application, software application, signal processing and control module, code that is native to a particular device, a hardware abstraction layer for a particular device, etc.). The device applications  1718  also include any system components or modules to implement embodiments of the techniques described herein. In this example, the device applications  1718  include an interface application  1722  and an input/output module  1724  (which may be the same or different as input/output module  114 ) that are shown as software modules and/or computer applications. The input/output module  1724  is representative of software that is used to provide an interface with a device configured to capture inputs, such as a touchscreen, track pad, camera, microphone, and so on. Alternatively or in addition, the interface application  1722  and the input/output module  1724  can be implemented as hardware, software, firmware, or any combination thereof. Additionally, the input/output module  1724  may be configured to support multiple input devices, such as separate devices to capture visual and audio inputs, respectively. 
     Device  1700  also includes an audio and/or video input-output system  1726  that provides audio data to an audio system  1728  and/or provides video data to a display system  1730 . The audio system  1728  and/or the display system  1730  can include any devices that process, display, and/or otherwise render audio, video, and image data. Video signals and audio signals can be communicated from device  1700  to an audio device and/or to a display device via an RF (radio frequency) link, S-video link, composite video link, component video link, DVI (digital video interface), analog audio connection, or other similar communication link. In an embodiment, the audio system  1728  and/or the display system  1730  are implemented as external components to device  1700 . Alternatively, the audio system  1728  and/or the display system  1730  are implemented as integrated components of example device  1700 . 
     CONCLUSION
