## Title
Trigger event based data feed of virtual universe data

## Abstract

Business owners in a virtual universe may want to create a data source that transmits a data feed when certain parameters are met. Functionality can be implemented within a virtual universe to create a data feed when a trigger event occurs. The data feed may include data about the trigger event itself and/or about an avatar that caused the trigger. Triggered data feeds can be used to derive statistics, monitor use of objects and space and bill for such use, etc. In such cases, the user may be notified, such as via email, of the new data feed, as well as instructions on how to subscribe to it in their RSS reader or other client. Alternatively, users may be given individual feeds wherein additional feeds are distributed as separate categories of the user's feed as opposed to creating a separate feed.

## Background
BACKGROUND
Embodiments of the inventive subject matter generally relate to the field of virtual universe systems, and more particularly, to creating trigger events based web data feeds of virtual universe avatar data.
Virtual universe applications allow people to socialize and interact in a virtual universe. A virtual universe (VU) is a computer-based simulated environment intended for its residents to traverse, inhabit, and interact through the use of avatars. Many VUs are represented using 3-D graphics and landscapes, and are populated by many thousands of users, known as residents. Other terms for VUs include metaverses and “3D Internet.”
Users of a virtual universe conduct business and engage in social interactions based on the representation of their avatars and the interaction of the avatars with asset, environment, and other avatar data served from the VU's simulated environment. Virtual economies are emerging as the rate of business and social interactions within VUs is rapidly increasing.
SUMMARY
Embodiments include a method directed to determining that a trigger event occurs in a virtual universe. The trigger event is associated with one or more virtual universe objects. Data associated with an avatar that causes that causes the trigger event in the virtual universe is captured. An update for a data feed utilizing the captured data associated with the avatar is generated. The trigger event is associated with the data feed.

DESCRIPTION OF EMBODIMENT(S)
The description that follows includes exemplary systems, methods, techniques, instruction sequences and computer program products that embody techniques of the present inventive subject matter. However, it is understood that the described embodiments may be practiced without these specific details. For instance, although examples refer to Really Simple Syndication (RSS), embodiments can be implemented with any current or future technology similar to RSS, such as the Atom Syndication Format. In other instances, well-known instruction instances, protocols, structures and techniques have not been shown in detail in order not to obfuscate the description.
Business transactions are becoming more prevalent in virtual universes. Functionality can be implemented within a VU to allow syndication of data feeds to subscribers outside the VU. Feeds collect and serve data from one or more VU objects and locations based on changes made to the VU either by the VU itself, or by avatars in the VU. A location in a virtual universe can be an area defined by at least three coordinates, as an example. Data feeds from a VU can be used to create a VU or non-VU application with and/or using the data feeds, to derive data from the data feeds, to monitor use of objects or space and billing for such use based on the data feeds, etc.
FIG. 1 depicts an example of data feed creation within a virtual universe. A perspective 101 of a virtual universe is supported by a virtual universe server 102 and includes various graphical objects (e.g., buildings, avatars, vehicles, etc.) that make up the perspective 101. In FIG. 1, the perspective 101 comprises building graphical objects 108 and 109. In stage A, the building 108 and the building 109 are identified as a source for a data feed (“data feed source”). An object is identified as a data feed source when a user or program selects the object and chooses an option to make the object a data feed source.
At stage B, a data feed creation unit 103, collects data from the data feed source. Examples of collected data are graphical images, effects data, textures, coordinates, metadata, tracked usage, scripts, etc. As an example, data collected from buildings 108 and 109 may be statistical data (e.g., how many avatars passed by in a certain period of time, how many avatars entered one of the buildings, etc.), snapshots of avatars in the building, capture of the entire scene, etc.
At stage C, the data feed creation unit 103 creates a data feed 107 for syndication (e.g., using Really Simple Syndication (RSS)). As an example, the collected data may be formatted for syndication with data types separated into various fields (e.g., date and time formatted into a timestamp field, graphical images or metadata formatted into a description field, etc.).
At stage D, a data feed syndication unit 105 sends the data feed 107 to a set of subscribed readers 111. Although a push type syndication model is described, embodiments can implement a pull type syndication model or a hybrid of push and pull syndication The subscribed readers 111 are applications running on various devices, examples of which include a computer 115, a personal digital assistant (PDA) 113, and a mobile phone 117. A data feed reader running on computer 115 displays the data in the feed 107. The feed 107 may not contain data about all objects shown in the perspective 101. Five buildings are shown in the perspective 101. The buildings 108 and 109 are selected as the data source. The feed 107 contains data pertaining to the buildings 108 and 109, but not the other three buildings.
For example, the buildings 108 and 109 are listed for rent as storefronts by a property management company. The property management company identified the buildings 108 and 109 as a data feed to collect traffic data to show perspective tenants. The RSS feed 107 may include data such as how many avatars passed the buildings 108 and 109, demographics of passersby, images of passersby, etc.
FIG. 2 depicts a flowchart of example operations for distributing a data feed to subscribers outside a VU. Flow begins at block 201, where one or more objects in a VU are identified as a data source for a data feed. Examples of objects that can be used as data sources are buildings, avatars, vehicles, etc.
At block 203, data from the data source is collected into a data feed. An object indicated as a data source may contain one or more additional objects. Data is collected for each additional object contained within the data source object. Examples of objects that contain one or more additional objects include buildings, store product displays, etc.
At block 205, the data is distributed to one or more data feed subscribers outside of the virtual universe. In some embodiments, the data feed may be distributed at certain time intervals (e.g., daily). In other embodiments, the data feed may be a continuous stream of updates. In some embodiments, the data feed may be distributed to a subset of subscribers. The selection of these embodiments may be based on one or more conditions being met. For example, the default embodiment may be to distribute a data feed to all subscribers at an interval of 30 minutes, but a data feed containing a continuous stream of updates to a subset of subscribers (e.g., system administrators, authorities, object owners, etc.) may also be distributed.
FIG. 3 is a flowchart depicting example operations for creating and transmitting a data feed from a virtual universe. Flow begins at block 301, where an object is identified as a data source. For example, a user selects an object and chooses an option to make the object a data source. As another example, a program selects an object based on a pattern match, such as a location visited by a threshold or percentage of avatars, an avatar engaging in sales above a threshold number or amount, etc. At block 303, it is determined if permission has been granted to use the object as a data source. In one example, a request for permission to use the object as a data source can be sent to an owner of the object which may include samples of data that may be syndicated. In another example, the owner of the object can set a permission configuration associated with the object. If permission is granted to use the object as a data source, flow continues at block 305. If permission is not granted to use the object as a data source, flow ends.
At block 305, the data source is added to an inventory associated with the user's avatar. The inventory is a set of assets that are available to the user within the virtual universe. The inventory may contain tangible items such as clothing and vehicles and intangible items such as scripts and images. While the data source resides in the user's inventory, the user is considered to be subscribed to a data feed associated with the data source.
At block 307, data from the data source is aggregated into a data feed.
At block 309, the data is transmitted to subscribed feed readers outside the virtual universe and flow ends.
Data feed transmission can occur at certain intervals (i.e., daily). As an example, a user maintains an account in several VUs to work as a marketing consultant for several client companies that run virtual retail outlets in the VUs. In order to avoid logging into several VUs every day, the consultant implements an RSS feed from each of the VU retail centers. The RSS feeds provide periodic scene aggregates to an RSS reader application that allows switching between retail centers for daily site tours of each virtual store. The consultant may also create data feeds that collect statistical data over time, such as number and amount of sales, number of avatars in the store, demographics of avatars in the store, etc. A feed may be created to derive graphical data representing correlations between statistical data and avatar activity over time. For example, a feed can contain plots of avatar traffic flow in the store over a day. The data can be analyzed to determine the most and least popular areas of the store, navigation problems within the store, etc.
Data feed transmission can occur continuously. For example, a company is interested in introducing a certain number of new customers to a VU per day. The company wishes to allow new users to tour the VU, but due to server load cannot instantiate each guest avatar into the VU interface, or due to a lack of user willingness to install the VU client in order to tour the VU. Instead, the company can allow potential users to subscribe to an RSS feed. An RSS scene aggregator application provided by the company can render scenes at specific locations in each region of the VU. The web feed scene aggregator can also provide data sufficient for a limited view of each region. To limit computing resources to display the scene data, a partial representation of the scene data for each region may be collected into the data feed. For example, collected scene data may be limited to a certain number of objects and/or avatars, avatars may be represented by low resolution shapes, objects and/or avatars may be represented by outlines instead of graphics, etc.
In some cases, a user may want to create a data source that transmits a data feed when certain parameters are met. Functionality can be implemented within a virtual universe to create a data feed when a trigger event occurs. The data feed may include data about the trigger event itself and/or about an avatar that caused the trigger. Triggered data feeds can be used to derive statistics, monitor use of objects and space and bill for such use, etc. In such cases, the user may be notified, such as via email, of the new data feed, as well as instructions on how to subscribe to it in their RSS reader or other client. Alternatively, users may be given individual feeds wherein additional feeds are distributed as separate categories of the user's feed as opposed to creating a separate feed.
FIG. 4 is a flowchart depicting example operations for creating a triggered data feed. At block 401, one or more objects in a virtual universe are associated with a trigger. A trigger event occurs when one or more indicated conditions associated with one or more objects have been met. Conditions are indicated by a user when the trigger event is created.
At block 403, the trigger event for a data feed is indicated. The data feed is indicated by the user after creating the trigger event.
At block 405, data associated with an avatar in the virtual universe that causes the trigger event is captured. Examples of data associated with an avatar include the avatar's name, the avatar's unique identifier, the email address of the avatar's owner, demographic data about the avatar and/or the user of the avatar, etc.
At block 407, the data feed is updated to indicate the captured data. The data feed may be transmitted to a feed reader, used to derive other data, aggregated into another data feed, etc. In addition, the data feed may be updated to literally indicate the captured data, to indicate data derived from the captured data, to indicate a modified version of the captured data, etc.
FIG. 5 is a flowchart depicting example operations for creating and distributing a triggered data feed. Flow begins at block 501, where a data feed trigger event is defined in a virtual universe. At block 502, a data feed source is indicated for the data feed trigger event. For example, avatars, in general, are indicated as the data feed source for the trigger event. A data feed trigger event is defined by one or more conditions with one or more objects. The trigger event occurs when the one or more conditions have been satisfied. Example conditions include an avatar coming within a threshold distance from an object or location, an avatar picking up an object, an avatar entering a building, an avatar changing an attribute of an object, arrival of a particular time, etc. In addition, embodiments can implement nested dependent conditions. For instance, a trigger event can be defined with a first condition that a current time be within a given range and a second condition that a given number of avatars be within a threshold distance of at least two of five objects identified as a data feed source.
At block 503, it is determined if the trigger event has occurred. If the trigger event has occurred, flow continues at block 505. If the trigger event has not occurred, flow continues at block 503.
At block 505, data about an avatar causing the trigger event and/or data about the trigger event is captured. An example of a trigger event associated with a concert venue is an avatar crossing a boundary that defines the area of the concert venue. The condition is satisfied and the trigger event occurs when the avatar walks through a doorway of the venue. Data captured when the avatar entered the venue may include a time stamp of when the trigger event occurs, a unique identifier of the avatar, etc. Another example of condition is an avatar touching an interactive display in a museum. The condition is satisfied and the trigger event occurs when the avatar touches the display. Data captured may include the amount of time the avatar interacted with the display, the number of times the display was touched throughout the day, etc.
In addition, a trigger event for a data feed may have more than one condition. For example, a store owner may want to analyze the effectiveness of a product display. Conditions can be set up to detect an avatar stopping in front of the display, touching the display, picking up a product from the display, etc.
At block 507, the data feed is updated. Embodiments can accumulate data feed updates and update the data feed at certain intervals in batches, can update the data feed at every occurrence of a trigger event, etc. In addition, configurations can be set regarding the creation and transmission of data feeds for multiple objects and/or trigger events. For example, a user may wish to monitor trigger events for several different objects in a virtual universe. Each object may create an independent data feed. The user can set a configuration to receive the independent data feeds from each object or aggregate the independent feeds into one inclusive data feed.
FIG. 6 depicts an example use of triggered data feeds in a virtual universe. An avatar 603 and a rental bicycle 605 exist within a virtual universe 601. The rental bicycle is an asset of a bicycle rental shop 613. At stage A, selection of the rental bicycle 605 by avatar 603 is detected by a data source trigger detection unit 607. The data source trigger detection unit 607 captures the unique identifier and bicycle usage data (e.g., model of bicycle chosen, how long the bicycle was used, distance traveled, a graphical map view of path traversed, etc.).
At stage B, a data feed file 609 is created by the data source trigger detection unit 607. At stage C, a data feed syndication unit 611 sends the data feed to the bicycle rental shop 613. In one example, the data feed is sent to an owner of the bicycle rental shop 613 via a feed reader outside the VU. In another example, the data feed is sent to a feed reader inside the VU that monitors use of the assets of the bicycle rental shop 613. Notifications may be sent to an avatar belonging to the owner through communication services in the VU (e.g., instant message, email, etc.) At stage D, the bicycle rental shop 613 uses the data to bill the avatar for use of the bicycle. In some embodiments, the billing may be an automated response to the trigger event in the data feed. In other embodiments, the billing may be manually initiated by the owner of the asset. The bicycle rental shop can conduct market research by setting up a data feed to accumulate data over a period of time to analyze popularity of certain models of bicycles, characteristics of avatars that rent bicycles, distances the bicycles are ridden, paths taken, etc.
Triggered data feeds can be used to reward users for certain behaviors in a VU. As an example, an avatar may be given a small amount of revenue for entering a park and being exposed to an advertisement. As another example, an avatar may be given a free song download for attending a concert and being one of the first 100 avatars to enter the venue.
In addition, triggered data feeds can be used to monitor the use of spaces by avatars and charge owners of the avatars for use. A space is defined as an area within specific boundaries in the virtual universe. For example, an owner of a convention center in a virtual universe can define a space that is part of the convention center. The owner can monitor avatar activity within the space such as time spent in the space, corporate booths visited in the space, number of avatars in the space, etc.
It should be understood that the depicted flowchart are examples meant to aid in understanding embodiments and should not be used to limit embodiments or limit scope of the claims. Embodiments may perform additional operations, fewer operations, operations in a different order, operations in parallel, and some operations differently. For instance, referring to FIG. 3, permission to use an object as a data source may not be implemented in certain embodiments because all objects within some VU may be used as a data source by default. In addition, with reference to FIG. 4, a data feed may be conditioned upon multiple triggers. Additional operations may be performed to determine if additional trigger parameters have been met and/or a given time period has elapsed since the initial trigger.
