BACKGROUND

0003Since the beginning of the computer age, various techniques of human-computer interaction have been developed and implemented to help make computers easier to use. For example, the now common graphical user interface ("GUI") paradigm has made selecting programs easier because a user can point to an icon related to a desired program, rather than having to type in the program's name.

0004However, with the advent of ever more complex computing machinery has come seemingly more complex graphical user interfaces offering many levels of choices. A user can be presented with so many levels of choices in a user interface that finding the desired option becomes an unwelcome chore. As a result, a user may tend to avoid choices that may in fact be desirable. The large number of choices thus serves as a barrier for the user.

SUMMARY

0005The described technologies can provide various user interface arrangements and related functionality. For example, various application-centric user interface techniques can be employed.

0006In some examples, an application-centric user interface is presented to a user. In some examples, a user can add, update, or launch programs from the application-centric portion.

0007In some examples, the application-centric user interface includes an activity center by which a user can perform various actions related to the applications.

0008In a described implementation, the applications include game-related software. For example, a user can be presented with the available games and related information. In some examples, multiplayer online games can be launched.

0009Additional features and advantages will be made apparent from the following detailed description of illustrated embodiments, which proceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION

Example 1- Exemplary System Overview

0011Various of the examples described herein can make use of application-centric user interface techniques. With the advent of ever-more complex user interfaces, application-centric user interface techniques can avoid the frustration associated with being unable to easily find applications and perform tasks for the applications. For example, application-centric user interface techniques can treat applications in a special way and include an area of the user interface limited to applications (e.g., other types of items, such as files, are not listed in the area). Such an approach can be an improvement over a system that merely presents applications as part of a file system that includes a myriad of other items, such as files.

0012In addition, various of the techniques described herein can lead to a more rich presentation of applications, such as when presented by an operating system shell. In this way, an application publisher can customize their application's shell presentation. The techniques can accommodate a variety of applications from different application publishers.

Example 2- Exemplary User Interface Presentations

0013FIG. 1A shows a screen shot of an exemplary application-centric user interface 100. In the example, there are two or more application tiles 122 which display representations of respective applications in a pane 120. Items displayed in the pane 120 can be limited to representations of applications (e.g., representations of other items or files do not appear).

0014FIG. 1B shows a screen shot of another exemplary application-centric user interface 100. In the example, in addition to the two or more application tiles 122, there are the recent application pane 130, the task pane 140, and the information pane 150. An implementation may use one or more of the illustrated panes 130, 140, 150.

0015The most recently launched application pane 130 can show tiles for one or more (e.g., three) of the most recently launched applications. Or, some other mechanism can be used to denote the most recently launched application(s).

0016The task pane 140 presents one or more tasks that can be performed for the user interface, such as navigating to different pages within the user interface. Some tasks may be application-specific, while others may not operate on a particular application. In the example, a "view wish list" option is shown. When activated (e.g., by clicking), the "view wish list" option navigates to a page showing a list of one or more applications that a user has designated as being in a "wish list." For example, a user may be considering purchasing such applications or have already decided that such applications are desired and will be purchased upon release.

0017The information pane 150 can present one or more links 122, which when activated (e.g., by clicking), navigate to a detail page for the application indicated by the link. The links can be limited to those having fresh information, such as new information made available in the past <i>n</i> days (e.g., configurable by a user).

0018In any of the examples, areas of the user interface shown as panes may or may not be a visual boundary between the panes. Thus, the panes may alternatively be areas of the user interface without visual boundaries. Additional, fewer, or other items can be included. For example, a menu bar can present additional features or options.

Example 3- Exemplary Tiles

0019To facilitate a rich presence for applications in a user interface, the exemplary tiles described herein can present a graphical representation of an application and other information related to the application. FIG. 2A is a screen shot of an exemplary application tile 200 for use in an application-centric user interface, such as the user interfaces of FIGS. 1A and 1B. In the example, the application's name 210, a graphical (e.g., iconic, photographic, or artistic) representation 220 of the application, and a publisher name 230 are included in the tile 200. Alternatively, fewer, additional, or different items can be shown.

0020FIG. 2B is a screen shot of an alternative exemplary application tile 200 for use in an application-centric user interface, such as the user interfaces of FIGS. 1A and 1B. In the example, the application's name 210, a graphical (e.g., iconic, photographic, or artistic) representation 220 of the application, and a publisher name 230 are included in the tile 200. Also included is an indication of a date for the application (e.g., when the application was last run or when it was published) 240 and a link 250 to details (e.g., a detail page) of the application. Alternatively, fewer, additional, or different items can be shown.

0021FIG. 2C is a screen shot of an alternative exemplary application tile 200 for use in an application-centric user interface, such as the user interfaces of FIGS. 1A and 1B. In the example, the application's name 210, a graphical (e.g., iconic, photographic, or artistic) representation 220 of the application, and a publisher name 230 are included in the tile 200. Also included is an information link 270 indicating that new information is available from the publisher of the application. Upon activation of the information link the new information can be presented. Alternatively, fewer, additional, or different items can be shown.

0022FIG. 2D is a screen shot of an alternative exemplary application tile 200 for use in an application-centric user interface, such as the user interfaces of FIGS. 1A and 1B. In the example, the application's name 210 and a graphical (e.g., iconic, photographic, or artistic) representation 220 of the application are included in the tile 200. Also included is an indication 280 of one or more tasks that can be performed for the application. Such an indication, when activated, initiates performance of the task. The indication 280 of a task can be included in any of the tiles described herein and can be used to initiate any of the tasks described herein. Alternatively, fewer, additional, or different items can be shown.

0023In any of the examples, activation (e.g., clicking or double clicking) of the graphical representation 220 can launch (e.g., execute) the respective application.

Example 4- Alternative Exemplary User Interface Presentations

0024FIG. 3A shows a screen shot 300 of an alternative exemplary application-centric user interface. In the example, a task pane 322 shows one or more tasks 352A, 352B, 352N that can be performed on the applications represented by the representations 342A, 342B, 342N. For example, a user can select one of the applications 342A, 342B, 342N and then select a task 352A, 352B, 352N for the application (e.g., by clicking). Alternatively, fewer, additional, or different items can be shown. If desired, the items displayed in the pane 332 can be limited to representations of applications (e.g., representations of other items or files do not appear).

0025FIG. 3B shows a screen shot 300 of another alternative exemplary application-centric user interface. The example is similar to FIG. 3A, but also includes an activity center tasks pane 362 (e.g., similar to the task pane 140 of FIG. 1) and the information pane 372 (e.g., similar to the information pane 150 of FIG. 1).

0026In any of the examples, activation (e.g., clicking or double clicking) of the graphical representation 342A, 342B, 342N can launch (e.g., execute) the respective application. The representations 342A, 342B, 342N of the applications can be accompanied by information about the application (e.g., application name and the like). Alternatively, fewer, additional, or different items can be shown.

Example 5- Alternative Exemplary User Interface Presentations

0027FIG. 4 is a block diagram showing relationships between pages in an application-centric user interface. For purposes of discussion, the user interface presentations 402, 412, 414, 416 are called "pages." When the application-centric user interface is first entered, a user is presented with the welcome page 402. Upon activating an item (e.g., the details item 250 of FIG. 2) for navigating to information about a particular application (e.g., an application detail page), the respective application page 412, 414, 416 is presented. The user can then navigate back to the welcome page 402 from any of the application pages 412, 414, 416 (e.g., by activating an item presented on the page 412, 414, 416). As shown, two or more application pages 412, 414, 416 can be included. Collectively, the pages are sometimes called an "application activity center" because various activities related to applications can be accomplished via the pages.

0028Additional pages not shown but possibly implemented include an application wish list. Further, few, or different pages can be implemented. The welcome page 402 can take the form of any of the application-centric user interfaces shown above (e.g., the interface 100 of FIG. 1).

Example 6- Exemplary Application Detail Pages

0029FIG. 5A is a screen shot of exemplary detail page 500 presenting information for an application. Such a detail page 500 can be displayed when a detail page for a respective application is requested by a user (e.g., by activating the details item 250 of FIG. 2) and can be related to the welcome page 1902 as shown in FIG. 4). In the example, a representation (e.g., iconic, photographic, or artistic) of the application 512 is shown along with information 514 (e.g., application name) about the application. In addition, one or more task items 518 are shown. By activating a task item (e.g., by clicking on it), the associated task (e.g., any of the tasks described herein) is performed.

0030FIG. 5B shows a screen shot of an alternative exemplary detail page 500 presenting information for an application. Such a detail page 500 can be displayed when a detail page for a respective application is requested by a user (e.g., by activating the details item 250 of FIG. 2) and can be related to the welcome page 1902 as shown in FIG. 19). The pane 510 shows various items functioning as described for FIG. 5B. In addition, the detail page 500 includes a fresh information pane 520 showing an information link 524, which, when activated, navigates to the indicated information.

0031In addition, the detail page 500 includes an installation details pane 530. For example, the program's file location, installation size, date installed, copyright information, preferred operating system, patch history, or some combination thereof can be displayed. Alternatively, fewer, additional, or different items can be shown. Application publishers can create additional custom categories, which may or may not include publisher-created object code modules that provide additional information relevant to the application for the user's benefit.

0032Also, the detail page 500 includes a saved documents pane 540, which has representations 542A, 542B, and 542C of saved documents for the application. Activation of the representation opens the document (e.g., and launches the application if appropriate).

0033Finally, in the example, the capability rating system details pane 550 shows the recommended capability rating for the application, the minimum capability rating for the application, and the user computer's capability rating. The capability rating gives an easily-understood rating roughly indicating the computing resources required to execute the application. In this way, a user can be forewarned that an application will not run or will not run well on the user computer.

0034In any of the examples, activation (e.g., clicking or double clicking) of the graphical representation 512 can launch (e.g., execute) the respective application.

Example 7- Exemplary Application-Centric User Interface in Operating System Shell

0035Any of the user interfaces shown in the examples can be presented as part of a user interface for an operating system shell. For example, if the operating system shell depicts the file system of the computer, the user interfaces can be presented as a part of the file system.

0036FIG. 6 is a screen shot of an exemplary application-centric user interface 624 presented as part of a user interface 600 for an operating system shell. In the example, an operating system shell presents the application-centric portion of the user interface 624 in a window on the desktop 602, along with a pane 642 and an activatable item 652.

0037The other windows 632, 634 may be presented by the operating system shell or by applications. The operating system shell may present other windows, such as those for navigating throughout the file system or configuring the operating system.

Example 8- Exemplary Relationships of Application-Centric User Interface in Operating System Shell

0038FIG. 7 is a block diagram 700 showing relationships between folders 702, 712, 714, 716 presented as part of a user interface by the operating system shell. In the example, a user can navigate from the "My Computer" folder 702 to the "My Applications" folder 712 or any of the other folders 714, 716. The folders can be customized per user, so that the operating system will present a different set of applications for each user. If desired, an application can be simultaneously installed across users so that it shows up in more than one user's folder.

0039In practice, the folders may be shown as iconic or list representations of the items in the folders, or in the case of the application folder 712, a more rich presentation can be presented as shown in any of the examples herein.

Example 9- Exemplary Application Metadata File

0040FIG. 8 shows contents of an exemplary application metadata file. The application metadata file can store information about an application and can be used when presenting the application's information in the application-centric user interface.

0041Thus, the file 800 can include the application's name, a name of the application's publisher, a location to find link data for presenting informational links, capability rating system information, references to graphical representations of the application, numerous other items, or some combination thereof.

0042If desired, the file 800 can follow mark-up (e.g., XML) conventions. The file 800 can be associated with a signature to authenticate origin and integrity of the file 800. Additionally, the file 800 can include information (e.g., hyperlinks) for previewing (e.g., acquiring a demo version) or purchasing the application.

Example 10- Exemplary Relationships between an Operating System Shell, Application Metadata Files, and Applications

0043FIG. 9 is a block diagram 900 showing exemplary relationships between an operating system shell 910, a database of application metadata files 920, and a plurality of applications 960A, 960B, 960N. The operating system shell 910 can thus present any of the user interfaces described herein by referring to the application metadata files 920 for the applications 960A, 960B, 960N. The shell can also configure and launch the applications 960A, 960B, 960N as desired via the selections received from a user at the user computer via the user interfaces.

Example 11- Exemplary Relationships between Application Metadata Files and Specialized Metadata Files

0044FIG. 10 is a Venn diagram 1000 showing relationships between application metadata files 1010 and specialized application metadata files 1020. For example, the specialized application metadata files can qualify as application metadata files (e.g., follow the same schema) but also include additional information specific to the specialized application (e.g., games).

Example 12- Exemplary Acquisition of Application Metadata Files

0045Application metadata files can be acquired in a variety of ways. For example, if an application is provided via a CD-ROM, the application metadata file can be stored thereon and copied therefrom. If an application is downloaded via a network connection, the file can be downloaded as part of the installation package. Or, as described herein, the application metadata file can be acquired without installing the application, such as when adding the application to a wish list or for an application hosted on a remote web site. In some cases, the application metadata file can be incorporated into or referred to by an application manifest. Such a manifest can be provided to indicate the items within a software package.

0046FIG. 11 is a screen shot of an exemplary page 1100 (e.g., web page) having a review of an application from which an application metadata file can be acquired. In the example, a hyperlink 1116 is presented as part of the page 1100. Activation of the hyperlink 1116 results in acquisition of the application metadata file (e.g., the file is stored in the database 920 and added to a wish list).

0047The application metadata file can be identified by a special file extension (e.g., ADF, GDF) or other mechanism. An HTML tag in the hyperlink can indicate that the file is to be added to a wish list. The file can be accompanied by a digital signature so that the origin and integrity of the file can be authenticated.

Example 13- Exemplary Use of Metadata Files to Install Software

0048Any of the application metadata files described herein can be used to install software. FIG. 12 shows an exemplary method 1200 for achieving application installation via an application metadata file.

0049At 1210, the application metadata file is acquired. As described herein, the file can be acquired in a variety of ways.

0050At 1220, the application is evaluated. The operating system shell can facilitate evaluation by a user by providing links to information about the application or the online community, even before the application has been purchased or installed.

0051At 1230, the application is purchased. Billing information for the application software purchase can be collected electronically, and the purchase can be achieved by activating (e.g., clicking) on an item, which can operate with reference to information in the respective application metadata file.

0052At 1240, the application is installed. Installation can proceed according to a variety of methods, including standard ones offered by the operating system.

0053The method 1200 can also be applied to upgrades. For example, an upgrade can be evaluated before purchasing. In some cases, an upgrade may be of such a nature as to be considered a separate application (e.g., a major upgrade).

0054The described method 1200 can also be described as a method for marketing software. By presenting the user with an easy way to add a representation of the application to the operating system shell before the software is purchased, the user can more easily become part of the online community related to the application. In this way, the user can collect relevant information when deciding whether or when to purchase the application or an upgrade. Further, the application publisher can keep in contact with the user via informational links. In this way, targeted online marketing can be achieved without deluging the online community with mass email campaigns.

Example 14- Exemplary Accommodation of Legacy Applications

0055Upon installation of an operating system shell supporting the described application-centric user interface techniques (e.g., when upgrading the operating system), there may be one or more applications already present on the computer. Such applications may not be present in the interfaces unless manually added by the user.

0056Such applications are sometimes called "legacy" applications. The user may be very interested in such applications, so if they do not appear in the proper user interfaces, the user may be disappointed and not take advantage of the functionality described herein.

0057To facilitate accommodation of legacy application, various methods can be used. FIG. 1300 shows one such method 1300. The method 1300 can be performed by the operating system in the background as other applications are running. Over time, the method 1300 can identify the applications on the computer. For example, if the operating system contains a routine that scans the files in the file system, the method 1300 can run as part of the operating system routine. Alternatively, the method 1300 can be run all at once.

0058At 1310, a file is found during a scan. Files considered can be limited to executables. Then, at 1320, it is determined whether the file matches a fingerprint stored as part of the operating system. A fingerprinting technique can be used so that the application is verified to be a particular application without its being an exact copy. If a match is indicated, details for the file (e.g., location and associated application metadata file name) can be stored in a list. Subsequently, the list can be considered (e.g., when an application activity center is launched or resumed), and the application metadata files can be added (e.g., after appropriate configuration, if any) to the database (e.g., the database 920).

0059The described fingerprints and associated application metadata files can be provided as part of the operating system, an operating system upgrade, or provided on a remote Internet resource, such as a web server. The latter case provides flexibility in providing ongoing updates to the database of information for legacy applications. For example, application metadata files can be generated for the more popular application titles so that they eventually appear in the application activity center. Any number of other techniques can be used.

Example 15- Exemplary Application to Games

0060Any of the technologies described herein can be applied with advantage to games. An activity center limited to games (e.g., not depicting other applications) can be implemented. Games can be accommodated via a specialized application metadata file. Such a file can include additional information about the game, such as how to achieve multiplayer online game scenarios.

0061Further, when implemented as part of a user interface for the operating system shell, a game activity center can provide an easy way for users to manage and launch games. For example, the operating system shell can present a "my games" folder by which the game activity center is presented. Still further, instant messaging functionality can be incorporated into the game activity center. And, if the operating system supports contact objects, multiplayer online games can be initiated via reference to the contact objects.

0062Various other game-specific functionality can be incorporated. For example, an application tile can include a link for playing the most recently saved game. In a detail page, the <i>n</i> (e.g., 3) most recently saved games can be portrayed graphically (e.g., via a mini screen shot depicting the game situation when it was saved).

Example 16- Exemplary Game Detail Page

0063FIG. 14 is a screen shot showing an exemplary detail page 1400 for a game in a game activity center and can be used as an application detail page in any of the technologies described herein. In the example, a game detail pane 1430 includes a graphic (e.g., iconic, photographic, or artistic) representation 1412 of the game, the game's name, a comment from the publisher, the name of the publisher, the publisher's web site, the date the game was installed, the size of the game, and the date the game was last played. Such information can be stored in the game's metadata file (e.g., a specialized application metadata file) or otherwise stored or acquired. For example, certain often-changing information (e.g., date the game was installed and date the game was last played) can be stored outside the game's metadata file. The size of the game can be determined when the game is executed.

0064In addition, the pane 1430 includes an information links pane 1420, which includes an information link 1424, which, when activated (e.g., by clicking), navigates to the indicated information.

0065A task pane 1440 shows various tasks that can be achieved for the application (e.g., by activating the task item). For example, the game can be played by activating the button 1444. Other tasks include: continue the last saved game, play multi-player, play with buddies, review and install updates (e.g., upgrades or updates to data files), view saved games, search for new games, find similar games, visit an online forum for the game, visit an online community for the game, join an online chat room for the game, change or uninstall the game, go to the game's (official) webpage, check compatibility information for the game, check security information for the game, view usage history (e.g., when played, how long played, how often played), and show program files.

0066In practice, additional, fewer, or different items may be shown. In any of the examples, activation (e.g., clicking or double clicking) of the graphical representation 1412 can launch (e.g., execute) the respective application.

Example 17- Exemplary Multiplayer Online Game Scenario

0067FIG. 15 shows a block diagram 1500 illustrating an exemplary multiplayer online game scenario. In the example, the user computer 1510, and one or more buddy computers 1520A, 1520B, 1520N are in contact with the game server 1560 via the network 1540. Respective human players can be at the user and buddy computers. In this way, the players can participate in the same game to compete or cooperate in the game. The number of users can far exceed that shown. In some scenarios, one of the user or buddy computers can serve as the game server.

0068Contact information for the buddy computers 1520A, 1520B, 1520N can be stored on a buddy list. When determining whether buddies are playing a particular game or any games, the list can be consulted. If desired, consent can be acquired before adding a contact to a buddy list.

0069Although multiplayer online games have become very popular, they can still remain somewhat difficult to start. Various technologies described herein can simplify multiplayer online game user interface operation.

Example 18- Exemplary Relationships for Achieving Multiplayer Online Game Scenarios

0070FIG. 16 is a block diagram showing exemplary relationships 1600 for achieving multiplayer online game scenarios. In the example, the operating system shell 1610 interfaces with instant messaging functionality 1630 and a game application 1620. Also, if desired, the operating system shell 1610 can interface with one or more contact objects 1640 (e.g., stored in a database accessible by the operating system shell 1610).

0071The operating system shell 1610 is operable to interface with a user (e.g., via the operating system shell or an interface for the instant messaging functionality 1630) to receive directions regarding multiplayer game scenarios. The shell 1610 can then provide appropriate information to the game application 1620 to initiate or join the multiplayer online game.

0072In some cases, a multiplayer online game can be initiated or joined via the contact object 1640 (e.g., a user interface depicting information about an individual, such as a friend or buddy).

Example 19- Exemplary User Interface for Achieving Multiplayer Online Game Scenarios

0073FIG. 17 is a screen shot of a user interface 1700 for achieving an exemplary multiplayer online game scenario, such as that shown in FIG. 15. In the example, the user interface 1700 includes a user pane 1710, which includes a depiction 1712 (e.g., photograph) of the user of the computer, the user's name 1714, an indication 1716 of whether the user is online or not, and a motto of the user (e.g., a brief message to identify the user's personality among buddies or newcomers).

0074The example also includes a chat pane 1720, whereby the user can hold an online chat session (e.g., via messenger functionality) with other potential players. Text can be entered into the box 1722 and the button 1724 activated to send a message via the chat session.

0075The invited buddies pane 1730 includes depictions (e.g., photographs) of those buddies (e.g., remote users) whom the user has invited to play. Also included is the buddy's name and a quality rating of the buddy's connection (e.g., indicative of whether a dialup or broadband connection is available for the buddy). Additional buddies can be invited via the button 1732. In the example, the user is hosting the game (e.g., controls who is invited to the game). Other scenarios are possible.

0076The example further includes a game pane 1740 which displays a function 1742 and a list of games 1744.

0077Finally, a ready button 1752 can be activated by the user (or buddies at their respective computers) to indicate that they are ready to begin playing. Upon pressing the launch button 1756, the game is begun with the displayed buddies in the buddy pane 1730. Information in the game metadata file can be consulted to determine how to launch the game (e.g., how to submit the buddies for the online game).

0078The user interface 1700 can be arrived at in a variety of ways. For example, a game detail page can present a link (e.g., "play multiplayer" or "play with buddies") which, when activated, presents the interface 1700. Or, the user may be chatting with a buddy via the messaging software and be presented with an option by which the user interface 1700 is presented. Finally, an option can be presented when showing a list of buddies (e.g., in a contact list represented by contact objects) by which the user interface 1700 is presented. The associated players can be automatically listed in the buddy pane 1730 if desired.

0079Before the interface 1700 is presented, another user interface can be presented (e.g., "Who do you want to play this game with") by which a user selects buddies. Such a user interface can present various contact-related options (e.g., "my contacts," "company directory," "family address book," "recent contacts," "cell phone contacts," filters, or some combination thereof).

Example 20- Exemplary Rich Presence Via Content Rating System

0080In any of the game examples described herein, games can be associated via content rating in a content rating system. For example, a game can be rated as acceptable for all audiences, or for mature audiences only. The system can accommodate various content rating conventions (e.g., from different countries).

0081A user (e.g., with an administrator password) can configure the system so that certain users are designated as to play games of only certain specified content ratings. For example, a parent can specify that a child can play only games rated for "all audiences."

Example 21- Exemplary Rich Presence Via Capability Rating System

0082In any of the examples described herein, applications can be associated with a capability rating system ("CRS"). For example, a higher rating can indicate that greater computing resources are needed to run the game. A minimum as well as a recommended capability rating can be specified for the application. The rating can be compared with a rating of the user computer to see whether the application will run or run well on the user computer.

0083Further, discrete system requirements can be specified for an application. For example, certain applications may require specialized hardware (e.g., a graphics tablet or a game controller).

0084Certain options can be not presented based on the requirements specified. In practice, a user will be permitted to launch an application even if it only meets the minimum system requirements.

0085The capability system rating can be presented for the application when it is added on a wish list. In this way, the user can easily determine whether or how well the application will run on the user computer.

Example 22- Exemplary Rich Presence for Applications

0086In any of the examples described herein, combinations of one or more of the following can be presented for the application (e.g., as part of the tile for an application, on the application's detail page, or both): System Requirements (e.g., CRS), installation details (e.g., install folder, size on disk, date installed), patch history (e.g., filtered for the application), and saved document summary.

Example 23- Exemplary Rich Presence for Games

0087When presenting games in any of the examples herein, the following additional items can be presented: online game(s) currently in progress, saved game summary and preferred input device assignment.

Example 24- Exemplary Rich Presence for Applications

0088When listing applications in any of the examples herein, the lists can be ordered by any of a variety of criteria (e.g., by name/alphabetical, by genre, by publisher, by most recently run, size on disk).

0089When presenting application tiles, the following can be included: link(s) to new publisher content available; link(s) to online forums; link(s) to fan sites. When presenting games, the following can be presented: a content rating, whether buddies are online, a list of buddies online, or some combination thereof. When presenting more than one game at a time, a summary of games for which updated information is available can be presented.

Example 25- Exemplary Application Tiles

0090For any of the application tiles shown herein, the tiles can include various information. The tiles can include any combination of the following information: date installed, release date (emphasize if on wish list), last run, hours run, publisher name and logo, developer name and logo, installation path, patch history, CRS data, update notification, extended description, screenshots, saved documents.

0091The tiles can include various items which, when activated, perform a task (e.g., the item behaves as a hyperlink or a command. Possible tasks include the following: find a new application, review and install updates, view system capabilities, check for updates, view my wish list, return to welcome page, run, continue last document, view saved documents, change/remove, find similar applications, visit forum, join chat room, register application, view usage history, show installation folder, check for updates for this application online, email a friend about this application, buy this application, download the demo.

0092In addition or alternatively, in implementations accommodating games, the following information can be included: saved games, last played, hours played, number of buddies playing. The following tasks can be included: configure parental controls, play, continue last saved game, play with buddies, join an internet or LAN game session, create a new Internet or LAN game, find a new game, view saved games, find similar games, register game online.

Example 31- Exemplary Computing Environment

0099Figure 19 and the following discussion are intended to provide a brief, general description of a suitable computing environment for an implementation. While the technologies are described in the general context of computer-executable instructions of a computer program that runs on a computer and/or network device, the technologies may also be implemented in combination with other program modules. Generally, program modules include routines, programs, components, data structures, etc. that perform particular tasks or implement particular abstract data types. Moreover, the technologies may be practiced with other computer system configurations, including multiprocessor systems, microprocessor-based electronics, minicomputers, mainframe computers, network appliances, wireless devices, and the like. The extensions can be practiced in networked computing environments, or on stand-alone computers.

0100With reference to Figure 19, an exemplary system for implementation includes a conventional computer 1920 (such as personal computers, laptops, servers, mainframes, and other variety computers) includes a processing unit 1921, a system memory 1922, and a system bus 1923 that couples various system components including the system memory to the processing unit 1921. The processing unit may be any of various commercially available processors, including Intel x86, Pentium and compatible microprocessors from Intel and others, including Cyrix, AMD and Nexgen; Alpha from Digital; MIPS from MIPS Technology, NEC, IDT, Siemens, and others; and the PowerPC from IBM and Motorola. Dual microprocessors and other multi-processor architectures also can be used as the processing unit 1921.

0101The system bus may be any of several types of bus structure including a memory bus or memory controller, a peripheral bus, and a local bus using any of a variety of conventional bus architectures such as PCI, VESA, AGP, Microchannel, ISA and EISA, to name a few. The system memory includes read only memory (ROM) 1924 and random access memory (RAM) 1925. A basic input/output system (BIOS), containing the basic routines that help to transfer information between elements within the computer 1920, such as during start-up, is stored in ROM 1924.

0102The computer 1920 further includes a hard disk drive 1927, a magnetic disk drive 1928, e.g., to read from or write to a removable disk 1929, and an optical disk drive 1930, e.g., for reading a CD-ROM disk 1931 or to read from or write to other optical media. The hard disk drive 1927, magnetic disk drive 1928, and optical disk drive 1930 are connected to the system bus 1923 by a hard disk drive interface 1932, a magnetic disk drive interface 1933, and an optical drive interface 1934, respectively. The drives and their associated computer-readable media provide nonvolatile storage of data, data structures, computer-executable instructions, etc. for the computer 1920. Although the description of computer-readable media above refers to a hard disk, a removable magnetic disk and a CD, it should be appreciated by those skilled in the art that other types of media which are readable by a computer, such as magnetic cassettes, flash memory cards, digital video disks, Bernoulli cartridges, and the like, may also be used in the exemplary operating environment.

0103A number of program modules may be stored in the drives and RAM 1925, including an operating system 1935, one or more application programs 1936, other program modules 1937, and program data 1938; in addition to an implementation 1956.

0104A user may enter commands and information into the computer 1920 through a keyboard 1940 and pointing device, such as a mouse 1942. These and other input devices are often connected to the processing unit 1921 through a serial port interface 1946 that is coupled to the system bus, but may be connected by other interfaces, such as a parallel port, game port or a universal serial bus (USB). A monitor 1947 or other type of display device is also connected to the system bus 1923 via an interface, such as a video adapter 1948. In addition to the monitor, computers typically include other peripheral output devices (not shown), such as speakers and printers.

0105The computer 1920 operates in a networked environment using logical connections to one or more remote computers, such as a remote computer 1949. The remote computer 1949 may be a server, a router, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer 1920, although only a memory storage device 1950 has been illustrated. The logical connections depicted include a local area network (LAN) 1951 and a wide area network (WAN) 1952. Such networking environments are commonplace in offices, enterprise-wide computer networks, intranets and the Internet.

0106When used in a LAN networking environment, the computer 1920 is connected to the local network 1951 through a network interface or adapter 1953. When used in a WAN networking environment, the computer 1920 typically includes a modem 1954 or other means for establishing communications (e.g., via the LAN 1951 and a gateway or proxy server 1955) over the wide area network 1952, such as the Internet. The modem 1954, which may be internal or external, is connected to the system bus 1923 via the serial port interface 1946. In a networked environment, program modules depicted relative to the computer 1920, or portions thereof, may be stored in the remote memory storage device. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers may be used.

Example 32- Exemplary Application Programming Interface

0107FIGS. 20-26 are a programming language excerpt 2000 specifying an exemplary application programming interface ("API") for achieving application installation via the technologies described herein. The described functions can be used, for example, when installing an application. Although the example proceeds with reference to computer games, the technologies can also be applied to applications in general.

0108Also, although the example code is in the C# language, any number of other programming languages can be used to implement an application programming interface. Further, the example shows that the applications are incorporated into the operating system shell via a folder named "My Games," however other folder names or way of incorporating into the operating system shell can be used.

0109Table 2 shows exemplary families of functions for an API, and Table 3 shows exemplary functions for an API. In the example, a "supported" title is a non-web, non-legacy title supported by the system; the web and legacy titles are still supported by the system. Additional, fewer, or different functions can be implemented. <tables id="tabl0002" num="0002"><table frame="all"><title>Table 2 -</title><tgroup cols="2" colsep="1" rowsep="1"><colspec colnum="1" colname="col1" colwidth="78.75mm" /><colspec colnum="2" colname="col2" colwidth="78.75mm" /><thead valign="top"><row><entry namest="col1" nameend="col2" align="left"><b>Exemplary API Function Families</b></entry></row><row><entry namest="col1" nameend="col1" align="left">Function Family</entry><entry namest="col2" nameend="col2" align="left">Description</entry></row></thead><tbody valign="top"><row><entry namest="col1" nameend="col1" align="left">Add<i>XXX</i></entry><entry namest="col2" nameend="col2" align="left">Install an application into "My Games"</entry></row><row><entry namest="col1" nameend="col1" align="left">Uninstall<i>XXX</i></entry><entry namest="col2" nameend="col2" align="left">Uninstall an application from "My Games"</entry></row><row><entry namest="col1" nameend="col1" align="left">Is<i>XXX</i>Installed</entry><entry namest="col2" nameend="col2" align="left">Check to see if the specific application is installed in "My Games"</entry></row><row rowsep="1"><entry namest="col1" nameend="col1" align="left"><i>GetXXX</i></entry><entry namest="col2" nameend="col2" align="left">Return the list of applications in "My Games"</entry></row></tbody></tgroup></table></tables><tables id="tabl0003" num="0003"><table frame="all"><title>Table 3 -</title><tgroup cols="2" colsep="1" rowsep="1"><colspec colnum="1" colname="col1" colwidth="78.75mm" /><colspec colnum="2" colname="col2" colwidth="78.75mm" /><thead valign="top"><row><entry namest="col1" nameend="col2" align="left"><b>Exemplary API Functions</b></entry></row><row><entry namest="col1" nameend="col1" align="left">Function</entry><entry namest="col2" nameend="col2" align="left">Description</entry></row></thead><tbody valign="top"><row><entry namest="col1" nameend="col1" align="left">AddLegacyTitle</entry><entry namest="col2" nameend="col2" align="left">Install a legacy application into the game activity center.</entry></row><row><entry namest="col1" nameend="col1" align="left">AddWebTitle</entry><entry namest="col2" nameend="col2" align="left">Install a web application into the game activity center.</entry></row><row><entry namest="col1" nameend="col1" align="left">AddSupportedTitle</entry><entry namest="col2" nameend="col2" align="left">Install a supported application into the game activity center.</entry></row><row><entry namest="col1" nameend="col1" align="left">GetMyGamesApps</entry><entry namest="col2" nameend="col2" align="left">Retrieves list of applications in the game activity center.</entry></row><row><entry namest="col1" nameend="col1" align="left">GetMyGamesSupportedApps</entry><entry namest="col2" nameend="col2" align="left">Retrieves list of supported applications in the game activity center.</entry></row><row><entry namest="col1" nameend="col1" align="left">GetMyGamesLegacyApps</entry><entry namest="col2" nameend="col2" align="left">Retrieves list of legacy applications in the game activity center.</entry></row><row><entry namest="col1" nameend="col1" align="left">GetMyGamesWebApps</entry><entry namest="col2" nameend="col2" align="left">Retrieves list of installed web applications in the game activity center.</entry></row><row><entry namest="col1" nameend="col1" align="left">IsAppInstalled</entry><entry namest="col2" nameend="col2" align="left">Checks to see if the specified app is installed in the game activity center as any kind of app.</entry></row><row><entry namest="col1" nameend="col1" align="left">IsLegacyTitleInstalled</entry><entry namest="col2" nameend="col2" align="left">Checks to see if the specified app is installed in the game activity center as a legacy app.</entry></row><row><entry namest="col1" nameend="col1" align="left">IsWebTitleInstalled</entry><entry namest="col2" nameend="col2" align="left">Checks to see if the specified app is installed in the game activity center as a web app.</entry></row><row><entry namest="col1" nameend="col1" align="left">UninstallWebTitle</entry><entry namest="col2" nameend="col2" align="left">Removes a web title from the game activity center.</entry></row><row><entry namest="col1" nameend="col1" align="left">UninstallSupportedTitle</entry><entry namest="col2" nameend="col2" align="left">Removes a supported title from the game activity center.</entry></row><row rowsep="1"><entry namest="col1" nameend="col1" align="left">UninstallLegacyTitle</entry><entry namest="col2" nameend="col2" align="left">Removes a legacy title from the game activity center.</entry></row></tbody></tgroup></table></tables>

Example 33- Exemplary Schema for Use with Application Metadata

0110FIGS. 27-31 specify an exemplary XML schema 2700 for use with application metadata. In the example, the metadata is stored in an "ADF" (e.g., a file with the .adf file extension).

0111In the example, the schema specifies that the metadata can include an application identifier identifying an application installable in an application activity center (e.g., "applicationid"), a displayable description of one or more tasks performable for the application when installed into the application activity center (e.g., "description" for "taskdata"), data indicating how to invoke the one or more tasks performable for the application when installed into the application activity center (e.g., "invokedata" for "taskdata"), and arguments for the one or more tasks performable for the application when installed in the application activity center (e.g., "arguments" for "taskdata"). Additional, fewer, or different elements can be defined for the schema.

Example 34- Exemplary Schema for Use with Computer Game Metadata

0112FIGS. 32-35 specify an exemplary XML schema 3200 for use with application metadata. In the example, the metadata is stored in a "GDF" (e.g., a file with the .gdf file extension) and extends the "ADF" schema of FIGS. 27-31. Additional, fewer, or different elements can be defined for the schema.

Example 35- Exemplary Schema for Use with Computer Game Metadata

0113FIGS. 36-38 specify an exemplary metadata 3600 for a particular game application called "Freecell." Metadata for other applications will differ accordingly.

Example 36- Exemplary Schema for Use with an Application Manifest

0114FIGS. 39-41 specify an excerpt of an exemplary XML schema for use with an application manifest. In the example, the manifest can specify application metadata by referring to an "ADF" or "GDF" file, such as one described in FIGS. 36-38 or any other application metadata file. By incorporating a reference to the metadata file in the manifest, the metadata file is considered part of the software package for the application and can be distributed therein. Additional, fewer, or different elements can be defined for the schema.
