Description
TECHNICAL FIELD
The present disclosure relates generally to generating images and providing try-on experiences using an interaction application.
BACKGROUND
Augmented reality (AR) is a modification of a real-world environment with the addition or overlay of virtual content. For example, in virtual reality (VR), a user is completely immersed in a virtual world, whereas in AR, the user is immersed in a world where virtual objects are combined or superimposed on the real world. An AR system aims to generate and present virtual objects that interact realistically with a real-world environment and with each other. Examples of AR applications can include single or multiple player video games, instant messaging systems, and the like.

DETAILED DESCRIPTION
The description that follows includes systems, methods, techniques, instruction sequences, and computing machine program products that embody illustrative examples of the disclosure. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide an understanding of various examples. It will be evident, however, to those skilled in the art, that examples may be practiced without these specific details. In general, well-known instruction instances, protocols, structures, and techniques are not necessarily shown in detail.
Typically, messaging applications and other social network platforms allow users to view a live or real-time camera feed that depicts the users wearing different items. For example, a user can activate a virtual try-on experience in which one or more AR items are placed on the user depicted in the image in real-time. This provides a user with the ability to visualize how different products look on the user before the user purchases the products. To activate such experiences, users can browse products through one software application, such as a website. The user can select a given product, such as a fashion item, depicted on the website.
Then, the user is presented with an option to launch an AR shopping experience application in which the user can virtually try on the selected product. A video depicting the user trying on the product is presented to the user in a separate application associated with the AR shopping experience. Namely, the user is navigated away from the website to a whole other experience to provide the user with the virtual try-on experience. The need to navigate the user away from the website makes online shopping difficult because the user has to continuously navigate back and forth between the AR try-on experience and the display of the products on the website. Having to navigate through a multitude of pages of information just to virtually try on certain products and to select new products to try on in a separate interface is discouraging and very disruptive. Also having to re-launch the AR experience each time a new product is selected consumes a great deal of resources and is incredibly inefficient.
The disclosed techniques seek to improve the efficiency of using an electronic device by providing a virtual try-on experience together with presentation of fashion items on a graphical user interface (GUI), such as a webpage on a website. Namely, as the user browses items on the webpage, the disclosed techniques automatically select a given fashion item that is on the webpage and update a video feed that depicts the user wearing an AR version of the given fashion item. The video feed can be presented alongside the GUI, such as in a window on top of the GUI or in a side-by-side arrangement adjacent to the GUI. This seamless interaction between browsing fashion items online and visualizing how different fashion items being viewed online look on the user enhances the overall experience and reduces the amount of resources needed to accomplish a task. Namely, the user does not need to continuously navigate between different pages of information (e.g., a page of the online GUI of fashion items and a page of the AR experience) to view the AR try-on experience for different fashion items. In this way, the overall user experience is improved and the amount of resources needed to accomplish a task is reduced.
This can reduce the overall time and expense incurred by users trying on different fashion items, such as shoes, shirts, earrings, watches, or other fashion items. As used herein, “article of clothing,” “fashion item,” and “garment” are used interchangeably and should be understood to have the same meaning. Article of clothing, garment, or fashion item can include a shirt, skirt, dress, shoes, purse, furniture item, household item, eyewear, eyeglasses, AR logos, AR emblems, pants, shorts, jackets, t-shirts, blouses, glasses, jewelry, earrings, bunny ears, a hat, earmuffs, or any other suitable item or object.
Specifically, the disclosed techniques display a GUI that includes a set of fashion items, such as two or more fashion items. The disclosed techniques receive a real-time video feed from a camera of the device, the real-time video feed depicting a person. The disclosed techniques retrieve a first AR fashion item corresponding to a first fashion item in the set of fashion items included in the GUI. The disclosed techniques modify the real-time video feed based on application of the first AR fashion item to the depiction of the person in the real-time video feed. The disclosed techniques present the modified real-time video feed together with the GUI comprising the set of fashion items. This improves the overall experience of the user in using the electronic device and reduces the overall amount of system resources needed to accomplish a task.
Networked Computing Environment
FIG. 1 is a block diagram showing an example interaction system 100 for facilitating interactions (e.g., exchanging text messages, conducting text audio and video calls, or playing games) over a network. The interaction system 100 includes multiple client systems 102, each of which hosts multiple applications, including an interaction client 104 and other applications 106. Each interaction client 104 is communicatively coupled, via one or more communication networks including a network 108 (e.g., the Internet), to other instances of the interaction client 104 (e.g., hosted on respective other user systems 102), an interaction server system 110 and third-party servers 112). An interaction client 104 can also communicate with locally hosted applications 106 using Applications Program Interfaces (APIs).
Each user system 102 may include multiple user devices, such as a mobile device 114, head-wearable apparatus 116, and a computer client device 118 that are communicatively connected to exchange data and messages.
An interaction client 104 interacts with other interaction clients 104 and with the interaction server system 110 via the network 108. The data exchanged between the interaction clients 104 (e.g., interactions 120) and between the interaction clients 104 and the interaction server system 110 includes functions (e.g., commands to invoke functions) and payload data (e.g., text, audio, video, or other multimedia data).
The interaction server system 110 provides server-side functionality via the network 108 to the interaction clients 104. While certain functions of the interaction system 100 are described herein as being performed by either an interaction client 104 or by the interaction server system 110, the location of certain functionality either within the interaction client 104 or the interaction server system 110 may be a design choice. For example, it may be technically preferable to initially deploy particular technology and functionality within the interaction server system 110 but to later migrate this technology and functionality to the interaction client 104 where a user system 102 has sufficient processing capacity.
The interaction server system 110 supports various services and operations that are provided to the interaction clients 104. Such operations include transmitting data to, receiving data from, and processing data generated by the interaction clients 104. This data may include message content, client device information, geolocation information, media augmentation and overlays, message content persistence conditions, social network information, and live event information. Data exchanges within the interaction system 100 are invoked and controlled through functions available via user interfaces (UIs) of the interaction clients 104.
Turning now specifically to the interaction server system 110, an Application Program Interface (API) server 122 is coupled to and provides programmatic interfaces to interaction servers 124, making the functions of the interaction servers 124 accessible to interaction clients 104, other applications 106 and third-party server 112. The interaction servers 124 are communicatively coupled to a database server 126, facilitating access to a database 128 that stores data associated with interactions processed by the interaction servers 124. Similarly, a web server 130 is coupled to the interaction servers 124 and provides web-based interfaces to the interaction servers 124. To this end, the web server 130 processes incoming network requests over the Hypertext Transfer Protocol (HTTP) and several other related protocols.
The Application Program Interface (API) server 122 receives and transmits interaction data (e.g., commands and message payloads) between the interaction servers 124 and the client systems 102 (and, for example, interaction clients 104 and other application 106) and the third-party server 112. Specifically, the Application Program Interface (API) server 122 provides a set of interfaces (e.g., routines and protocols) that can be called or queried by the interaction client 104 and other applications 106 to invoke functionality of the interaction servers 124. The Application Program Interface (API) server 122 exposes various functions supported by the interaction servers 124, including account registration; login functionality; the sending of interaction data, via the interaction servers 124, from a particular interaction client 104 to another interaction client 104; the communication of media files (e.g., images or video) from an interaction client 104 to the interaction servers 124; the settings of a collection of media data (e.g., a story); the retrieval of a list of friends of a user of a user system 102; the retrieval of messages and content; the addition and deletion of entities (e.g., friends) to an entity graph (e.g., a social graph); the location of friends within a social graph; and opening an application event (e.g., relating to the interaction client 104).
The interaction servers 124 host multiple systems and subsystems, described below with reference to FIG. 2.
Linked Applications
Returning to the interaction client 104, features and functions of an external resource (e.g., a linked application 106 or applet) are made available to a user via an interface of the interaction client 104. In this context, “external” refers to the fact that the application 106 or applet is external to the interaction client 104. The external resource is often provided by a third party but may also be provided by the creator or provider of the interaction client 104. The interaction client 104 receives a user selection of an option to launch or access features of such an external resource. The external resource may be the application 106 installed on the user system 102 (e.g., a “native app”), or a small-scale version of the application (e.g., an “applet”) that is hosted on the user system 102 or remote of the user system 102 (e.g., on third-party servers 112). The small-scale version of the application includes a subset of features and functions of the application (e.g., the full-scale, native version of the application) and is implemented using a markup-language document. In some examples, the small-scale version of the application (e.g., an “applet”) is a web-based, markup-language version of the application and is embedded in the interaction client 104. In addition to using markup-language documents (e.g., a .*ml file), an applet may incorporate a scripting language (e.g., a .*js file or a .json file) and a style sheet (e.g., a .*ss file).
In response to receiving a user selection of the option to launch or access features of the external resource, the interaction client 104 determines whether the selected external resource is a web-based external resource or a locally-installed application 106. In some cases, applications 106 that are locally installed on the user system 102 can be launched independently of and separately from the interaction client 104, such as by selecting an icon corresponding to the application 106 on a home screen of the user system 102. Small-scale versions of such applications can be launched or accessed via the interaction client 104 and, in some examples, no or limited portions of the small-scale application can be accessed outside of the interaction client 104. The small-scale application can be launched by the interaction client 104 receiving, from a third-party server 112 for example, a markup-language document associated with the small-scale application and processing such a document.
In response to determining that the external resource is a locally-installed application 106, the interaction client 104 instructs the user system 102 to launch the external resource by executing locally-stored code corresponding to the external resource. In response to determining that the external resource is a web-based resource, the interaction client 104 communicates with the third-party servers 112 (for example) to obtain a markup-language document corresponding to the selected external resource. The interaction client 104 then processes the obtained markup-language document to present the web-based external resource within a user interface of the interaction client 104.
The interaction client 104 can notify a user of the user system 102, or other users related to such a user (e.g., “friends”), of activity taking place in one or more external resources. For example, the interaction client 104 can provide participants in a conversation (e.g., a chat session) in the interaction client 104 with notifications relating to the current or recent use of an external resource by one or more members of a group of users. One or more users can be invited to join in an active external resource or to launch a recently-used but currently inactive (in the group of friends) external resource. The external resource can provide participants in a conversation, each using respective interaction clients 104, with the ability to share an item, status, state, or location in an external resource in a chat session with one or more members of a group of users. The shared item may be an interactive chat card with which members of the chat can interact, for example, to launch the corresponding external resource, view specific information within the external resource, or take the member of the chat to a specific location or state within the external resource. Within a given external resource, response messages can be sent to users on the interaction client 104. The external resource can selectively include different media items in the responses, based on a current context of the external resource.
The interaction client 104 can present a list of the available external resources (e.g., applications 106 or applets) to a user to launch or access a given external resource. This list can be presented in a context-sensitive menu. For example, the icons representing different ones of the application 106 (or applets) can vary based on how the menu is launched by the user (e.g., from a conversation interface or from a non-conversation interface).
System Architecture
FIG. 2 is a block diagram illustrating further details regarding the interaction system 100, according to some examples. Specifically, the interaction system 100 is shown to comprise the interaction client 104 and the interaction servers 124. The interaction system 100 embodies multiple subsystems, which are supported on the client-side by the interaction client 104 and on the server-side by the interaction servers 124. Example subsystems are discussed below and can include a browsing-based AR system 500 that enables a user to launch an AR experience in which a video depicting a user of the user system 102 is modified to overlay an AR fashion item corresponding to a fashion item presented in a GUI. An illustrative implementation of the browsing-based AR system 500 is shown and described in connection with FIG. 5 below.
Specifically, the browsing-based AR system 500 is a component that can be accessed by an AR/VR application implemented on the user system 102. The AR/VR application uses an RGB camera to capture a monocular image of a real-world object. The AR/VR application applies various trained machine learning techniques or machine learning models on the captured image of the real-world object to generate body landmark features representing the real-world object depicted in the images or videos and to apply one or more AR visual effects to the captured image or video based on body landmark features. In some implementations, the AR/VR application continuously captures images of the user and updates the body landmark features in real time or periodically to continuously or periodically update the applied one or more visual effects. This allows the user to move around in the real world and see the one or more visual effects update in real time.
An image processing system 202 provides various functions that enable a user to capture and augment (e.g., annotate or otherwise modify or edit) media content associated with a message.
A camera system 204 includes control software (e.g., in a camera application) that interacts with and controls hardware camera hardware (e.g., directly or via operating system controls) of the user system 102 to modify and augment real-time images captured and displayed via the interaction client 104.
The augmentation system 206 provides functions related to the generation and publishing of augmentations (e.g., media overlays) for images captured in real-time by cameras of the user system 102 or retrieved from memory of the user system 102. For example, the augmentation system 206 operatively selects, presents, and displays media overlays (e.g., an image filter or an image lens) to the interaction client 104 for the augmentation of real-time images received via the camera system 204 or stored images retrieved from memory 1006 of a user system 102. These augmentations are selected by the augmentation system 206 and presented to a user of an interaction client 104, based on a number of inputs and data, such as for example:
Social network information of the user of the user system 102.
An augmentation may include audio and visual content and visual effects. Examples of audio and visual content include pictures, texts, logos, animations, and sound effects. An example of a visual effect includes color overlaying. The audio and visual content or the visual effects can be applied to a media content item (e.g., a photo or video) at user system 102 for communication in a message, or applied to video content, such as a video content stream or feed transmitted from an interaction client 104. As such, the image processing system 202 may interact with, and support, the various subsystems of the communication system 208, such as the messaging system 210 and the video communication system 212.
A media overlay may include text or image data that can be overlaid on top of a photograph taken by the user system 102 or a video stream produced by the user system 102. In some examples, the media overlay may be a location overlay (e.g., Venice beach), a name of a live event, or a name of a merchant overlay (e.g., Beach Coffee House). In further examples, the image processing system 202 uses the geolocation of the user system 102 to identify a media overlay that includes the name of a merchant at the geolocation of the user system 102. The media overlay may include other indicia associated with the merchant. The media overlays may be stored in the databases 128 and accessed through the database server 126.
The image processing system 202 provides a user-based publication platform that enables users to select a geolocation on a map and upload content associated with the selected geolocation. The user may also specify circumstances under which a particular media overlay should be offered to other users. The image processing system 202 generates a media overlay that includes the uploaded content and associates the uploaded content with the selected geolocation.
The augmentation creation system 214 supports augmented reality developer platforms and includes an application for content creators (e.g., artists and developers) to create and publish augmentations (e.g., augmented reality experiences) of the interaction client 104. The augmentation creation system 214 provides a library of built-in features and tools to content creators including, for example custom shaders, tracking technology, and templates.
In some examples, the augmentation creation system 214 provides a merchant-based publication platform that enables merchants to select a particular augmentation associated with a geolocation via a bidding process. For example, the augmentation creation system 214 associates a media overlay of the highest bidding merchant with a corresponding geolocation for a predefined amount of time.
A communication system 208 is responsible for enabling and processing multiple forms of communication and interaction within the interaction system 100 and includes a messaging system 210, an audio communication system 216, and a video communication system 212. The messaging system 210 is responsible for enforcing the temporary or time-limited access to content by the interaction clients 104. The messaging system 210 incorporates multiple timers (e.g., within an ephemeral timer system 218) that, based on duration and display parameters associated with a message or collection of messages (e.g., a story), selectively enable access (e.g., for presentation and display) to messages and associated content via the interaction client 104. Further details regarding the operation of the ephemeral timer system 218 are provided below. The audio communication system 216 enables and supports audio communications (e.g., real-time audio chat) between multiple interaction clients 104. Similarly, the video communication system 212 enables and supports video communications (e.g., real-time video chat) between multiple interaction clients 104.
A user management system 220 is operationally responsible for the management of user data and profiles, and includes a social network system 222 that maintains information regarding relationships between users of the interaction system 100.
A collection management system 224 is operationally responsible for managing sets or collections of media (e.g., collections of text, image video, and audio data). A collection of content (e.g., messages, including images, video, text, and audio) may be organized into an “event gallery” or an “event story.” Such a collection may be made available for a specified time period, such as the duration of an event to which the content relates. For example, content relating to a music concert may be made available as a “story” for the duration of that music concert. The collection management system 224 may also be responsible for publishing an icon that provides notification of a particular collection to the user interface of the interaction client 104. The collection management system 224 includes a curation function that allows a collection manager to manage and curate a particular collection of content. For example, the curation interface enables an event organizer to curate a collection of content relating to a specific event (e.g., to delete inappropriate content or redundant messages). Additionally, the collection management system 224 employs machine vision (or image recognition technology) and content rules to curate a content collection automatically. In certain examples, compensation may be paid to a user to include user-generated content into a collection. In such cases, the collection management system 224 operates to automatically make payments to such users to use their content.
A map system 226 provides various geographic location functions and supports the presentation of map-based media content and messages by the interaction client 104. For example, the map system 226 enables the display of user icons or avatars (e.g., stored in profile data 302) on a map to indicate a current or past location of “friends” of a user, as well as media content (e.g., collections of messages including photographs and videos) generated by such friends, within the context of a map. For example, a message posted by a user to the interaction system 100 from a specific geographic location may be displayed within the context of a map at that particular location to “friends” of a specific user on a map interface of the interaction client 104. A user can furthermore share his or her location and status information (e.g., using an appropriate status avatar) with other users of the interaction system 100 via the interaction client 104, with this location and status information being similarly displayed within the context of a map interface of the interaction client 104 to selected users.
A game system 228 provides various gaming functions within the context of the interaction client 104. The interaction client 104 provides a game interface providing a list of available games that can be launched by a user within the context of the interaction client 104 and played with other users of the interaction system 100. The interaction system 100 further enables a particular user to invite other users to participate in the play of a specific game by issuing invitations to such other users from the interaction client 104. The interaction client 104 also supports audio, video, and text messaging (e.g., chats) within the context of gameplay, provides a leaderboard for the games, and also supports the provision of in-game rewards (e.g., coins and items).
An external resource system 230 provides an interface for the interaction client 104 to communicate with remote servers (e.g., third-party servers 112) to launch or access external resources, i.e., applications or applets. Each third-party server 112 hosts, for example, a markup language (e.g., HTML5) based application or a small-scale version of an application (e.g., game, utility, payment, or ride-sharing application). The interaction client 104 may launch a web-based resource (e.g., application) by accessing the HTML5 file from the third-party servers 112 associated with the web-based resource. Applications hosted by third-party servers 112 are programmed in JavaScript leveraging a Software Development Kit (SDK) provided by the interaction servers 124. The SDK includes Application Programming Interfaces (APIs) with functions that can be called or invoked by the web-based application. The interaction servers 124 host a JavaScript library that provides a given external resource access to specific user data of the interaction client 104. HTML5 is an example of technology for programming games, but applications and resources programmed based on other technologies can be used.
To integrate the functions of the SDK into the web-based resource, the SDK is downloaded by the third-party server 112 from the interaction servers 124 or is otherwise received by the third-party server 112. Once downloaded or received, the SDK is included as part of the application code of a web-based external resource. The code of the web-based resource can then call or invoke certain functions of the SDK to integrate features of the interaction client 104 into the web-based resource.
The SDK stored on the interaction server system 110 effectively provides the bridge between an external resource (e.g., applications 106 or applets) and the interaction client 104. This gives the user a seamless experience of communicating with other users on the interaction client 104 while also preserving the look and feel of the interaction client 104. To bridge communications between an external resource and an interaction client 104, the SDK facilitates communication between third-party servers 112 and the interaction client 104. A WebViewJavaScriptBridge running on a user system 102 establishes two one-way communication channels between an external resource and the interaction client 104. Messages are sent between the external resource and the interaction client 104 via these communication channels asynchronously. Each SDK function invocation is sent as a message and callback. Each SDK function is implemented by constructing a unique callback identifier and sending a message with that callback identifier.
By using the SDK, not all information from the interaction client 104 is shared with third-party servers 112. The SDK limits which information is shared based on the needs of the external resource. Each third-party server 112 provides an HTML5 file corresponding to the web-based external resource to interaction servers 124. The interaction servers 124 can add a visual representation (such as a box art or other graphic) of the web-based external resource in the interaction client 104. Once the user selects the visual representation or instructs the interaction client 104 through a GUI of the interaction client 104 to access features of the web-based external resource, the interaction client 104 obtains the HTML5 file and instantiates the resources to access the features of the web-based external resource.
The interaction client 104 presents a graphical user interface (e.g., a landing page or title screen) for an external resource. During, before, or after presenting the landing page or title screen, the interaction client 104 determines whether the launched external resource has been previously authorized to access user data of the interaction client 104. In response to determining that the launched external resource has been previously authorized to access user data of the interaction client 104, the interaction client 104 presents another graphical user interface of the external resource that includes functions and features of the external resource. In response to determining that the launched external resource has not been previously authorized to access user data of the interaction client 104, after a threshold period of time (e.g., 3 seconds) of displaying the landing page or title screen of the external resource, the interaction client 104 slides up (e.g., animates a menu as surfacing from a bottom of the screen to a middle or other portion of the screen) a menu for authorizing the external resource to access the user data. The menu identifies the type of user data that the external resource will be authorized to use. In response to receiving a user selection of an accept option, the interaction client 104 adds the external resource to a list of authorized external resources and allows the external resource to access user data from the interaction client 104. The external resource is authorized by the interaction client 104 to access the user data under an OAuth 2 framework.
The interaction client 104 controls the type of user data that is shared with external resources based on the type of external resource being authorized. For example, external resources that include full-scale applications (e.g., an application 106) are provided with access to a first type of user data (e.g., two-dimensional avatars of users with or without different avatar characteristics). As another example, external resources that include small-scale versions of applications (e.g., web-based versions of applications) are provided with access to a second type of user data (e.g., payment information, two-dimensional avatars of users, three-dimensional avatars of users, and avatars with various avatar characteristics). Avatar characteristics include different ways to customize a look and feel of an avatar, such as different poses, facial features, clothing, and so forth.
An advertisement system 232 operationally enables the purchasing of advertisements by third parties for presentation to end-users via the interaction clients 104 and also handles the delivery and presentation of these advertisements.
The browsing-based AR system 500 displays a GUI that includes a set of fashion items. The browsing-based AR system 500 receives a real-time video feed from a camera of the device, with the real-time video feed depicting a person. The browsing-based AR system 500 retrieves a first AR fashion item corresponding to a first fashion item in the set of fashion items included in the GUI. The browsing-based AR system 500 modifies the real-time video feed based on application of the first AR fashion item to the depiction of the person in the real-time video feed. The browsing-based AR system 500 presents the modified real-time video feed together with the GUI comprising the set of fashion items.
Data Architecture
FIG. 3 is a schematic diagram illustrating data structures 300, which may be stored in the database 304 of the interaction server system 110, according to certain examples. While the content of the database 304 is shown to comprise multiple tables, it will be appreciated that the data could be stored in other types of data structures (e.g., as an object-oriented database).
The database 304 includes message data stored within a message table 306. This message data includes, for any particular message, at least message sender data, message recipient (or receiver) data, and a payload. Further details regarding information that may be included in a message, and included within the message data stored in the message table 306, are described below with reference to FIG. 3.
An entity table 308 stores entity data, and is linked (e.g., referentially) to an entity graph 310 and profile data 302. Entities for which records are maintained within the entity table 308 may include individuals, corporate entities, organizations, objects, places, events, and so forth. Regardless of entity type, any entity regarding which the interaction server system 110 stores data may be a recognized entity. Each entity is provided with a unique identifier, as well as an entity type identifier (not shown).
The entity graph 310 stores information regarding relationships and associations between entities. Such relationships may be social, professional (e.g., work at a common corporation or organization), interest-based, or activity-based, merely for example. Certain relationships between entities may be unidirectional, such as a subscription by an individual user to digital content of a commercial or publishing user (e.g., a newspaper or other digital media outlet, or a brand). Other relationships may be bidirectional, such as a “friend” relationship between individual users of the interaction system 100.
Certain permissions and relationships may be attached to each relationship, and also to each direction of a relationship. For example, a bidirectional relationship (e.g., a friend relationship between individual users) may include authorization for the publication of digital content items between the individual users, but may impose certain restrictions or filters on the publication of such digital content items (e.g., based on content characteristics, location data or time of day data). Similarly, a subscription relationship between an individual user and a commercial user may impose different degrees of restrictions on the publication of digital content from the commercial user to the individual user, and may significantly restrict or block the publication of digital content from the individual user to the commercial user. A particular user, as an example of an entity, may record certain restrictions (e.g., by way of privacy settings) in a record for that entity within the entity table 308. Such privacy settings may be applied to all types of relationships within the context of the interaction system 100, or may selectively be applied to certain types of relationships.
The profile data 302 stores multiple types of profile data about a particular entity. The profile data 302 may be selectively used and presented to other users of the interaction system 100 based on privacy settings specified by a particular entity. Where the entity is an individual, the profile data 302 includes, for example, a user name, telephone number, address, settings (e.g., notification and privacy settings), as well as a user-selected avatar representation (or collection of such avatar representations). A particular user may then selectively include one or more of these avatar representations within the content of messages communicated via the interaction system 100, and on map interfaces displayed by interaction clients 104 to other users. The collection of avatar representations may include “status avatars,” which present a graphical representation of a status or activity that the user may select to communicate at a particular time.
Where the entity is a group, the profile data 302 for the group may similarly include one or more avatar representations associated with the group, in addition to the group name, members, and various settings (e.g., notifications) for the relevant group.
The database 304 also stores augmentation data, such as overlays or filters, in an augmentation table 312. The augmentation data is associated with and applied to videos (for which data is stored in a video table 314) and images (for which data is stored in an image table 316).
Filters, in some examples, are overlays that are displayed as overlaid on an image or video during presentation to a recipient user. Filters may be of various types, including user-selected filters from a set of filters presented to a sending user by the interaction client 104 when the sending user is composing a message. Other types of filters include geolocation filters (also known as geo-filters), which may be presented to a sending user based on geographic location. For example, geolocation filters specific to a neighborhood or special location may be presented within a user interface by the interaction client 104, based on geolocation information determined by a Global Positioning System (GPS) unit of the user system 102.
Another type of filter is a data filter, which may be selectively presented to a sending user by the interaction client 104 based on other inputs or information gathered by the user system 102 during the message creation process. Examples of data filters include current temperature at a specific location, a current speed at which a sending user is traveling, battery life for a user system 102, or the current time.
Other augmentation data that may be stored within the image table 316 includes augmented reality content items (e.g., corresponding to applying “lenses” or augmented reality experiences). An augmented reality content item may be a real-time special effect and sound that may be added to an image or a video.
A story table 318 stores data regarding collections of messages and associated image, video, or audio data, which are compiled into a collection (e.g., a story or a gallery). The creation of a particular collection may be initiated by a particular user (e.g., each user for which a record is maintained in the entity table 308). A user may create a “personal story” in the form of a collection of content that has been created and sent/broadcast by that user. To this end, the user interface of the interaction client 104 may include an icon that is user-selectable to enable a sending user to add specific content to his or her personal story.
A collection may also constitute a “live story,” which is a collection of content from multiple users that is created manually, automatically, or using a combination of manual and automatic techniques. For example, a “live story” may constitute a curated stream of user-submitted content from various locations and events. Users whose client devices have location services enabled and are at a common location event at a particular time may, for example, be presented with an option, via a user interface of the interaction client 104, to contribute content to a particular live story. The live story may be identified to the user by the interaction client 104, based on his or her location. The end result is a “live story” told from a community perspective.
A further type of content collection is known as a “location story,” which enables a user whose user system 102 is located within a specific geographic location (e.g., on a college or university campus) to contribute to a particular collection. In some examples, a contribution to a location story may employ a second degree of authentication to verify that the end-user belongs to a specific organization or other entity (e.g., is a student on the university campus).
As mentioned above, the video table 314 stores video data that, in some examples, is associated with messages for which records are maintained within the message table 306. Similarly, the image table 316 stores image data associated with messages for which message data is stored in the entity table 308. The entity table 308 may associate various augmentations from the augmentation table 312 with various images and videos stored in the image table 316 and the video table 314.
The databases 304 also include trained machine learning (ML) technique(s) 307 that stores parameters of one or more machine learning models that have been trained during training of the fashion item transfer system 500. For example, trained machine learning techniques 307 stores the trained parameters of one or more artificial neural network machine learning models or techniques.
Data Communications Architecture
FIG. 4 is a schematic diagram illustrating a structure of a message 400, according to some examples, generated by an interaction client 104 for communication to a further interaction client 104 via the interaction servers 124. The content of a particular message 400 is used to populate the message table 306 stored within the database 304, accessible by the interaction servers 124. Similarly, the content of a message 400 is stored in memory as “in-transit” or “in-flight” data of the user system 102 or the interaction servers 124. A message 400 is shown to include the following example components:
Message text payload 404: text, to be generated by a user via a user interface of the user system 102, and that is included in the message 400.
Message image payload 406: image data, captured by a camera component of a user system 102 or retrieved from a memory component of a user system 102, and that is included in the message 400. Image data for a sent or received message 400 may be stored in the image table 316.
Message video payload 408: video data, captured by a camera component or retrieved from a memory component of the user system 102, and that is included in the message 400. Video data for a sent or received message 400 may be stored in the image table 316.
Message audio payload 410: audio data, captured by a microphone or retrieved from a memory component of the user system 102, and that is included in the message 400.
Message augmentation data 412: augmentation data (e.g., filters, stickers, or other annotations or enhancements) that represents augmentations to be applied to message image payload 406, message video payload 408, or message audio payload 410 of the message 400. Augmentation data for a sent or received message 400 may be stored in the augmentation table 312.
Message duration parameter 414: parameter value indicating, in seconds, the amount of time for which content of the message (e.g., the message image payload 406, message video payload 408, message audio payload 410) is to be presented or made accessible to a user via the interaction client 104.
Message geolocation parameter 416: geolocation data (e.g., latitudinal and longitudinal coordinates) associated with the content payload of the message. Multiple message geolocation parameter 416 values may be included in the payload, each of these parameter values being associated with respect to content items included in the content (e.g., a specific image within the message image payload 406, or a specific video in the message video payload 408).
Message story identifier 418: identifier values identifying one or more content collections (e.g., “stories” identified in the story table 318) with which a particular content item in the message image payload 406 of the message 400 is associated. For example, multiple images within the message image payload 406 may each be associated with multiple content collections using identifier values.
Message tag 420: each message 400 may be tagged with multiple tags, each of which is indicative of the subject matter of content included in the message payload. For example, where a particular image included in the message image payload 406 depicts an animal (e.g., a lion), a tag value may be included within the message tag 420 that is indicative of the relevant animal. Tag values may be generated manually, based on user input, or may be automatically generated using, for example, image recognition.
Message sender identifier 422: an identifier (e.g., a messaging system identifier, email address, or device identifier) indicative of a user of the user system 102 on which the message 400 was generated and from which the message 400 was sent.
Message receiver identifier 424: an identifier (e.g., a messaging system identifier, email address, or device identifier) indicative of a user of the user system 102 to which the message 400 is addressed.
The contents (e.g., values) of the various components of message 400 may be pointers to locations in tables within which content data values are stored. For example, an image value in the message image payload 406 may be a pointer to (or address of) a location within an image table 316. Similarly, values within the message video payload 408 may point to data stored within an image table 316, values stored within the message augmentation data 412 may point to data stored in an augmentation table 312, values stored within the message story identifier 418 may point to data stored in a story table 318, and values stored within the message sender identifier 422 and the message receiver identifier 424 may point to user records stored within an entity table 308.
Browsing-Based AR System
FIG. 5 is a block diagram showing an example browsing-based AR system 500, according to example examples. The browsing-based AR system 500 includes a set of components 510 that operate on a set of input data (e.g., a video 501 including one or more frames depicting a person in a real-world environment). The browsing-based AR system 500 includes a fashion item portal module 512, a person detection module 514, an AR fashion item generation module 516, a fashion item selection module 517, an image modification module 518, and an image display module 520. All or some of the components of the browsing-based AR system 500 can be implemented by a server, in which case, the video 501 is provided to the server by the user system 102. In some cases, some or all of the components of the browsing-based AR system 500 can be implemented by the user system 102 or can be distributed across a set of user systems 102.
In some examples, the browsing-based AR system 500 displays a GUI including a set of fashion items. The browsing-based AR system 500 receives a real-time video feed from a camera of the device, with the real-time video feed depicting a person. The browsing-based AR system 500 retrieves a first AR fashion item corresponding to a first fashion item in the set of fashion items included in the GUI. The browsing-based AR system 500 modifies the real-time video feed based on application of the first AR fashion item to the depiction of the person in the real-time video feed and presents the modified real-time video feed together with the GUI including the set of fashion items.
In some examples, the modified real-time video feed is presented in a window on top of the GUI. In some examples, the window is circular or other geometric shape. In some examples, the modified real-time video feed is presented next to the GUI without overlaying any of the set of fashion items included in the GUI.
In some examples, the browsing-based AR system 500 accesses a code segment representing the GUI. The browsing-based AR system 500 searches the code segment to identify a list of the set of fashion items and selects, as the first fashion item, an individual fashion item that is positioned first in the list of the set of fashion items. In some examples, the browsing-based AR system 500 generates the first AR fashion item to resemble the first fashion item in the set of fashion items.
In some examples, the browsing-based AR system 500 accesses a server associated with the GUI to retrieve the first AR fashion item corresponding to the individual fashion item in the list of the set of fashion items. In some examples, the code segment includes an HTML document code (or other markup language document code) used to generate the display of the GUI.
In some examples, the browsing-based AR system 500 accesses a code segment representing the GUI and searches the code segment to identify a list of the set of fashion items. The browsing-based AR system 500 obtains one or more fashion item attributes associated with each of the fashion items in the list of the set of fashion items from the code segment.
In some examples, the browsing-based AR system 500 applies one or more machine learning models to the real-time video feed to estimate one or more attributes of the person depicted in the real-time video feed. The browsing-based AR system 500 matches the one or more attributes of the person depicted in the real-time video feed to the one or more fashion item attributes obtained from the code segment. For example, the browsing-based AR system 500 estimates an apparent age, gender, skin tones, and so forth of the person depicted in the real-time video feed. The browsing-based AR system 500 also retrieves stored preferences, such as types of clothing, genres of clothing, season of clothing, and so forth based on a shopping history of the person and/or what the person depicted in the video is currently wearing. The browsing-based AR system 500 matches any or all of the estimated features of the person and their shopping preferences to the fashion item attributes (e.g., gender, clothing style, genre of clothing, season of clothing, age of the clothing, and so forth) to find a matching fashion item for selection and application of the corresponding AR item or object to the person depicted in the video.
In some examples, the browsing-based AR system 500 ranks the fashion items in the list of the set of fashion items based on a result of matching the one or more attributes of the person depicted in the real-time video feed to the one or more fashion item attributes obtained from the code segment. The browsing-based AR system 500 selects, as the first fashion item, an individual fashion item that is ranked higher than all other fashion items in the list of the set of fashion items.
In some examples, the set of fashion items includes a first set of fashion items. In such cases, the browsing-based AR system 500 receives input to update the GUI to present a second set of fashion items and automatically updates the real-time video feed based on the second set of fashion items.
In some examples, the browsing-based AR system 500 retrieves a second AR fashion item corresponding to a second fashion item in the second set of fashion items included in the updated GUI. The browsing-based AR system 500 modifies the real-time video feed based on application of the second AR fashion item to the depiction of the person in the real-time video feed instead of the first AR fashion item.
In some examples, the real-time video feed is modified in response to receiving the input to update the GUI without receiving a separate request to apply the second AR fashion item to the depiction of the person. In some examples, the browsing-based AR system 500 automatically presents an indicator in association with the first fashion item of the set of fashion items displayed in the GUI to identify which of the set of fashion items is being represented by the application of the first AR fashion item to the depiction of the person in the real-time video feed.
In some examples, the indicator includes a highlight region or cursor. In some examples, the GUI includes a 2D layout of the set of fashion items. In some examples, the browsing-based AR system 500 applies one or more machine learning models to the real-time video feed to generate tracking information for the person depicted in the real-time video feed and continuously updates the real-time video feed to modify placement of the first AR fashion item on the depiction of the person in the real-time video feed based on the tracking information generated by the one or more machine learning models.
For example, the fashion item portal module 512 can receive a user request to launch a web-based shopping experience or access a web-based shopping portal. Namely, the fashion item portal module 512 can present a web browser. The fashion item portal module 512 can receive input from the user who types in the website address of an online shopping merchant. In response, the fashion item portal module 512 retrieves the HTML document associated with the webpage for the specified website. The fashion item portal module 512 processes the HTML document and presents a GUI that includes a list or set of fashion items available from the merchant. The GUI can be navigable to allow the user to browse different pages and update the display to present different sets of fashion items. For example, in response to a swipe left/right gesture, the identifiers of different fashion items are updated to represent different sets of fashion items.
For example, as shown in the HTML document 600 of FIG. 6, the fashion item portal module 512 receives the HTML document 600 from a remote server or website. The fashion item portal module 512 processes the HTML document 600 to display fashion items in the GUI according to the instructions or code of the HTML document 600.
In some cases, in response to launching the GUI to present the set of fashion items, the fashion item portal module 512 activates a front-facing camera feed of the user system 102. The fashion item portal module 512 receives and/or accesses a real-time camera feed from the front-facing or rear-facing camera of the user system 102. The camera feed can depict a real-world person or a body part of a real-world person, such as a face, torso, arms, legs, hips, or any other body part or body parts of the person. The fashion item portal module 512 provides the camera feed that includes one or more frames that depict the person or body part of the person to the person detection module 514.
The person detection module 514 implements one or more machine learning models (e.g., one or more neural networks) that have been trained to detect and track one or more persons and/or body parts in one or more video frames. For example, during training, the machine learning model of the person detection module 514 receives a given training image (or video) from a plurality of training images (or videos) that depict one or more persons and/or body parts. The plurality of training images is associated with corresponding ground truth markers or indications of the persons and/or body parts depicted in the training images and can be received or accessed from training image data stored in data structures 300. The person detection module 514 applies one or more machine learning models to a given training image. The person detection module 514 generates estimated tracking information for the persons and/or body parts depicted in the given training image.
The person detection module 514 obtains a known or predetermined ground-truth tracking information corresponding to the given training image. The person detection module 514 compares (computes a deviation between) the estimated tracking information with the ground truth tracking information. Based on a difference threshold of the comparison (or deviation), the person detection module 514 updates one or more coefficients or parameters and obtains one or more additional training images from the training data.
After a specified number of epochs or batches of training images have been processed and/or when a difference threshold (or deviation) (computed as a function of a difference or deviation between the estimated tracking information and the ground-truth tracking information) reaches a specified value, the person detection module 514 completes training, and the parameters and coefficients of the person detection module 514 are stored as a trained machine learning technique.
In some examples, the person detection module 514 can be used to detect one or more persons and/or body parts in an image of a real-world environment. The person detection module 514 can provide tracking information for persons and/or body parts estimated from the captured images to the AR fashion item generation module 516. The AR fashion item generation module 516 in combination with the image modification module 518 can then overlay one or more AR fashion items on the persons and/or body parts depicted in the images based on the estimated tracking information received from the person detection module 514 to generate an augmented image. The augmented image can be routed to the image display module 520 for presentation on the dedicated portion of a display screen, such as in a circular window on top of the GUI that includes the set of fashion items or next to the GUI in a side-by-side arrangement.
In some examples, the fashion item portal module 512 provides the HTML document 600 to the fashion item selection module 517. The fashion item selection module 517 processes the HTML document 600 to select one or more fashion items that are included in the GUI presented on the user system 102. In some cases, the fashion item selection module 517 searches the HTML document 600 for a fashion item field 610. The fashion item field 610 can indicate the start of a list of fashion items that correspond to the fashion items being presented on the GUI on the user system 102. In some examples, the fashion item selection module 517 selects a first fashion item field 612 that is on the list of fashion items. Namely, the first fashion item field 612 can correspond to the top most and/or left-most fashion item that is currently being presented on the GUI. The fashion item selection module 517 can retrieve an AR link 616 corresponding to the first fashion item field 612. The fashion item selection module 517 can access the AR link 616 to retrieve an AR version of the first fashion item that is presented on the GUI that resembles the look of the first fashion item. The fashion item selection module 517 provides the AR version of the first fashion item to the AR fashion item generation module 516.
The AR fashion item generation module 516 receives the AR version of the first fashion item and overlays the AR version of the first fashion item on top of the real-time video feed being captured by the front-facing or rear-facing camera of the user system 102. In some cases, the AR fashion item generation module 516 uses tracking information for the body parts or person depicted in the real-time video feed to continuously adjust a position of the AR version of the fashion item on the real-time video feed. This results in a realistic display that depicts the person in the real-time video feed wearing the AR version of the fashion item. As the person moves around the video feed, the AR version of the fashion item also moves to maintain its position on a particular body part, such as the upper body or lower body of the person.
In some cases, the fashion item selection module 517 can determine that the AR link 616 is missing for the first fashion item field 612. In such cases, the fashion item selection module 517 can apply one or more machine learning models to generate a 3D AR version of the first fashion item. Namely, the fashion item selection module 517 can retrieve a 2D image of the first fashion item from the first fashion item field 612. The fashion item selection module 517 applies the one or more machine learning models to the 2D image to generate a 3D representation of the first fashion item. The fashion item selection module 517 then animates the 3D representation to convert the 3D representation to an AR element or item. The fashion item selection module 517 then provides the AR element or item that resembles the 2D image of the first fashion item to the AR fashion item generation module 516 to overlay or augment a real-time video depicting a person wearing the AR element or item.
In some examples, the fashion item selection module 517 receives from the person detection module 514 one or more features of the person depicted in the real-time video feed. The fashion item selection module 517 can retrieve from an attributes field 614 a list of fashion item attributes that describe the first fashion item corresponding to the first fashion item field 612. The fashion item selection module 517 can also retrieve from respective attributes fields the list of fashion item attributes of each fashion item that is depicted and included in the GUI. The fashion item selection module 517 can match the attributes of the person depicted in the real-time video feed to the attributes of the fashion items that have been retrieved from the HTML document 600.
The fashion item selection module 517 can then rank each of the fashion item fields in the HTML document 600 based on how close the fashion item attributes match the attributes of the person. For example, the fashion item selection module 517 can assign a first rank to a first fashion item in the GUI in response to determining that a first quantity of fashion item attributes of the first fashion item match the attributes of the person depicted in the real-time video feed. The fashion item selection module 517 can assign a second rank to a second fashion item in the GUI in response to determining that a second quantity of fashion item attributes of the second fashion item match the attributes of the person depicted in the real-time video feed. The second quantity can include fewer fashion item attributes than the first quantity and so the second rank can be lower than the first rank. For example, the fashion item selection module 517 can determine that the second fashion item has fashion item features corresponding to a male garment and the first fashion item has fashion item features corresponding to a female garment. The fashion item selection module 517 can determine that the attributes of the person depicted in the real-time video feed correspond to a female. In such cases, the fashion item selection module 517 ranks the first fashion item greater than the second fashion item because the first fashion item includes fashion item features corresponding to the female garment and the person features correspond to a female.
The fashion item selection module 517 can select a top ranked fashion item in the ranked list of fashion items. The fashion item selection module 517 can retrieve or generate an AR version of the selected top ranked fashion item. The fashion item selection module 517 provides the AR version of the fashion item to the AR fashion item generation module 516 to modify a video feed depicting the person, such as to overlay the AR version of the fashion item on the video feed. The fashion item selection module 517 can continuously update the fashion item and the corresponding AR version of the fashion item that is selected as the GUI is updated to present different sets of fashion items. For example, the fashion item selection module 517 can receive an updated HTML document reflecting a different set of fashion items that are included, such as in response to a user input requesting to navigate to a different portion of the GUI or webpage. In response, the fashion item selection module 517 updates the selection of the fashion item to select a second fashion item and corresponding second AR fashion item that resembles the second fashion item. The fashion item selection module 517 provides the updated selection of the second AR fashion item to the AR fashion item generation module 516 to modify the video feed to depict the person wearing the second AR fashion item instead of the first AR fashion item version.
FIG. 7 shows an illustrative GUI 700 combined with an AR experience, according to some examples. Specifically, the browsing-based AR system 500 receives a user request to access the GUI 700, such as in response to receiving a user selection of a portal associated with a merchant (e.g., a website). The GUI 700 presents a 2D image 710 that includes images of one or more fashion items 720. The browsing-based AR system 500 selects a first fashion item 722 from the one or more fashion items 720 depicted in the GUI 700. The browsing-based AR system 500 generates or accesses a first AR fashion item corresponding to the first fashion item 722 (e.g., the first fashion item image). The first fashion item 722 can correspond to the very first (e.g., top left) fashion item in a list of fashion items.
The browsing-based AR system 500 receives a real-time video feed depicting a person or body part of a person, such as from a front-facing camera of the user system 102. The browsing-based AR system 500 applies the first AR fashion item (or a portion of the first AR fashion item) on the particular portion of the body part being depicted in the real-time video feed. For example, if only shoulders are being depicted in the real-time video feed and the first AR fashion item corresponds to a shirt, the browsing-based AR system 500 only applies the shoulder portions of the first AR fashion item to the real-world shoulders depicted in the real-time video feed. As new portions of the real-world person come into view, such as a torso, the browsing-based AR system 500 updates the real-time video feed to apply the torso portions of the first AR fashion item to the real-world torso depicted in the real-time video feed.
The browsing-based AR system 500 presents the modified real-time video feed in a window 730, such as a circular window on a square window, on the GUI 700. In this way, the window 730 is presented together with the one or more fashion items 720 depicted in the GUI. The modified real-time video feed presented in the window 730 includes a depiction of the person 732 or body part of the person overlaid with a portion of the first AR fashion item 734.
The browsing-based AR system 500 can receive input requesting access to another portion of the webpage. For example, the browsing-based AR system 500 can receive a swipe left gesture across a screen on which the GUI 700 is presented. In response, the browsing-based AR system 500 updates the GUI 700 to present a second GUI 800, shown in FIG. 8. The second GUI 800 includes a second set of fashion items 820 among other items from a 2D image 810 presented on the user system 102. The browsing-based AR system 500 can select a second fashion item 822 from the second set of fashion items 820 presented in the second GUI 800. The second fashion item can correspond to a fashion item that has more fashion item attributes that match features of the person depicted in a video feed captured by the front-facing or rear-facing camera of the user system 102 than all other fashion items in the fashion items 820. In some cases, the browsing-based AR system 500 presents an indicator, such as a highlight region, bordering the second fashion item 822 that has been selected.
The browsing-based AR system 500 updates the GUI 800 to present a window 830 with an updated AR fashion item 834 corresponding to the second fashion item 822. Namely, the window 830 presents a real-time video feed depicting the person 832 or body part wearing the AR fashion item 834 corresponding to the second fashion item 822 that has been selected and that appears in the updated GUI 800 instead of the portion of the first AR fashion item 734. Specifically, in response to receiving input that navigates to a different portion of the webpage to update the displayed set of fashion items in the GUI, the browsing-based AR system 500 automatically updates the real-time video feed to depict a different AR fashion item as being worn by the person or body part in the real-time video feed.
The browsing-based AR system 500 can receive input from the user that selects any of the fashion items depicted in the GUI 700 or second GUI 800. For example, the user can tap a different fashion item image depicted in the second GUI 800. In a similar manner, the browsing-based AR system 500 updates the video feed to present the AR version of the fashion item corresponding to the fashion item selected by the user instead of the AR version of the automatically selected fashion item.
FIG. 9 is a flowchart of a process 900, in accordance with some examples. Although the flowchart describes the operations as a sequential process, many of the operations can be performed in parallel or concurrently. In addition, the order of the operations may be re-arranged. A process is terminated when its operations are completed. A process may correspond to a method, a procedure, and the like. The steps of methods may be performed in whole or in part, may be performed in conjunction with some or all of the steps in other methods, and may be performed by any number of different systems or any portion thereof, such as a processor included in any of the systems.
At operation 901, the browsing-based AR system 500 (e.g., a server or user system 102) displays a GUI comprising a set of fashion items, as discussed above. For example, as shown in FIG. 7, the browsing-based AR system 500 displays one or more fashion items 720 in a GUI 700.
At operation 902, the browsing-based AR system 500 receives a real-time video feed from a camera of the device, with the real-time video feed depicting a person, as discussed above. For example, the browsing-based AR system 500 receives a real-time video feed from a camera of the user system 102.
At operation 903, the browsing-based AR system 500 retrieves a first AR fashion item corresponding to a first fashion item in the set of fashion items included in the GUI, as discussed above. For example, the browsing-based AR system 500 retrieves an AR fashion item corresponding to the first fashion item 722.
At operation 904, the browsing-based AR system 500 modifies the real-time video feed based on application of the first AR fashion item to the depiction of the person in the real-time video feed, as discussed above. For example, the browsing-based AR system 500 overlays the AR fashion item on a corresponding body part depicted in the received video stream.
At operation 905, the browsing-based AR system 500 presents the modified real-time video feed together with the GUI comprising the set of fashion items, as discussed above. For example, the browsing-based AR system 500 presents a window 730 depicting the person 732 wearing the first AR fashion item 734.

For example, the instructions 1002 may cause the machine 1000 to execute any one or more of the methods described herein. The instructions 1002 transform the general, non-programmed machine 1000 into a particular machine 1000 programmed to carry out the described and illustrated functions in the manner described. The machine 1000 may operate as a standalone device or may be coupled (e.g., networked) to other machines. In a networked deployment, the machine 1000 may operate in the capacity of a server machine or a client machine in a server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment.

The instructions 1002 may also reside, completely or partially, within the main memory 1016, within the static memory 1018, within machine-readable medium 1022 within the storage unit 1020, within at least one of the processors 1004 (e.g., within the processor's cache memory), or any suitable combination thereof, during execution thereof by the machine 1000.
The I/O components 1008 may include a wide variety of components to receive input, provide output, produce output, transmit information, exchange information, capture measurements, and so on. The specific I/O components 1008 that are included in a particular machine will depend on the type of machine. For example, portable machines such as mobile phones may include a touch input device or other such input mechanisms, while a headless server machine will likely not include such a touch input device. It will be appreciated that the I/O components 1008 may include many other components that are not shown in FIG. 10. In various examples, the I/O components 1008 may include user output components 1024 and user input components 1026.

With respect to cameras, the user system 102 may have a camera system comprising, for example, front cameras on a front surface of the user system 102 and rear cameras on a rear surface of the user system 102. The front cameras may, for example, be used to capture still images and video of a user of the user system 102 (e.g., “selfies”), which may then be augmented with augmentation data (e.g., filters) described above. The rear cameras may, for example, be used to capture still images and videos in a more traditional camera mode, with these images similarly being augmented with augmentation data. In addition to front and rear cameras, the user system 102 may also include a 360° camera for capturing 360° photographs and videos.
Further, the camera system of the user system 102 may include dual rear cameras (e.g., a primary camera as well as a depth-sensing camera), or even triple, quad or penta rear camera configurations on the front and rear sides of the user system 102.

Software Architecture
FIG. 11 is a block diagram 1100 illustrating a software architecture 1102, which can be installed on any one or more of the devices described herein. The software architecture 1102 is supported by hardware such as a machine 1104 that includes processors 1106, memory 1108, and I/O components 1110. In this example, the software architecture 1102 can be conceptualized as a stack of layers, where each layer provides a particular functionality. The software architecture 1102 includes layers such as an operating system 1112, libraries 1114, frameworks 1116, and applications 1118. Operationally, the applications 1118 invoke API calls 1120 through the software stack and receive messages 1122 in response to the API calls 1120.
The operating system 1112 manages hardware resources and provides common services. The operating system 1112 includes, for example, a kernel 1124, services 1126, and drivers 1128. The kernel 1124 acts as an abstraction layer between the hardware and the other software layers. For example, the kernel 1124 provides memory management, processor management (e.g., scheduling), component management, networking, and security settings, among other functionalities. The services 1126 can provide other common services for the other software layers. The drivers 1128 are responsible for controlling or interfacing with the underlying hardware. For instance, the drivers 1128 can include display drivers, camera drivers, BLUETOOTH® or BLUETOOTH® Low Energy drivers, flash memory drivers, serial communication drivers (e.g., USB drivers), WI-FI® drivers, audio drivers, power management drivers, and so forth.
The libraries 1114 provide a common low-level infrastructure used by the applications 1118. The libraries 1114 can include system libraries 1130 (e.g., C standard library) that provide functions such as memory allocation functions, string manipulation functions, mathematic functions, and the like. In addition, the libraries 1114 can include API libraries 1132 such as media libraries (e.g., libraries to support presentation and manipulation of various media formats such as Moving Picture Experts Group-4 (MPEG4), Advanced Video Coding (H.264 or AVC), Moving Picture Experts Group Layer-3 (MP3), Advanced Audio Coding (AAC), Adaptive Multi-Rate (AMR) audio codec, Joint Photographic Experts Group (JPEG or JPG), or Portable Network Graphics (PNG)), graphics libraries (e.g., an OpenGL framework used to render in two dimensions (2D) and three dimensions (3D) in a graphic content on a display), database libraries (e.g., SQLite to provide various relational database functions), web libraries (e.g., WebKit to provide web browsing functionality), and the like. The libraries 1114 can also include a wide variety of other libraries 1134 to provide many other APIs to the applications 1118.
The frameworks 1116 provide a common high-level infrastructure that is used by the applications 1118. For example, the frameworks 1116 provide various graphical user interface (GUI) functions, high-level resource management, and high-level location services. The frameworks 1116 can provide a broad spectrum of other APIs that can be used by the applications 1118, some of which may be specific to a particular operating system or platform.
In an example, the applications 1118 may include a home application 1136, a contacts application 1138, a browser application 1140, a book reader application 1142, a location application 1144, a media application 1146, a messaging application 1148, a game application 1150, and a broad assortment of other applications such as a third-party application 1152. The applications 1118 are programs that execute functions defined in the programs. Various programming languages can be employed to create one or more of the applications 1118, structured in a variety of manners, such as object-oriented programming languages (e.g., Objective-C, Java, or C++) or procedural programming languages (e.g., C or assembly language). In a specific example, the third-party application 1152 (e.g., an application developed using the ANDROID™ or IOS™ software development kit (SDK) by an entity other than the vendor of the particular platform) may be mobile software running on a mobile operating system such as IOS™, ANDROID™, WINDOWS® Phone, or another mobile operating system. In this example, the third-party application 1152 can invoke the API calls 1120 provided by the operating system 1112 to facilitate functionalities described herein.

A component may be a packaged functional hardware unit designed for use with other components and a part of a program that usually performs a particular function of related functions. Components may constitute either software components (e.g., code embodied on a machine-readable medium) or hardware components.
A “hardware component” is a tangible unit capable of performing certain operations and may be configured or arranged in a certain physical manner. In various examples, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware components of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware component that operates to perform certain operations as described herein.
A hardware component may also be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware component may include dedicated circuitry or logic that is permanently configured to perform certain operations. A hardware component may be a special-purpose processor, such as a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC). A hardware component may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, a hardware component may include software executed by a general-purpose processor or other programmable processors. Once configured by such software, hardware components become specific machines (or specific components of a machine) uniquely tailored to perform the configured functions and are no longer general-purpose processors. It will be appreciated that the decision to implement a hardware component mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software), may be driven by cost and time considerations. Accordingly, the phrase “hardware component” (or “hardware-implemented component”) should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein.
Considering examples in which hardware components are temporarily configured (e.g., programmed), each of the hardware components need not be configured or instantiated at any one instance in time. For example, where a hardware component comprises a general-purpose processor configured by software to become a special-purpose processor, the general-purpose processor may be configured as respectively different special-purpose processors (e.g., comprising different hardware components) at different times. Software accordingly configures a particular processor or processors, for example, to constitute a particular hardware component at one instance of time and to constitute a different hardware component at a different instance of time. Hardware components can provide information to, and receive information from, other hardware components. Accordingly, the described hardware components may be regarded as being communicatively coupled. Where multiple hardware components exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) between or among two or more of the hardware components. In examples in which multiple hardware components are configured or instantiated at different times, communications between such hardware components may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware components have access. For example, one hardware component may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware component may then, at a later time, access the memory device to retrieve and process the stored output. Hardware components may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information). The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented components that operate to perform one or more operations or functions described herein.
As used herein, “processor-implemented component” refers to a hardware component implemented using one or more processors. Similarly, the methods described herein may be at least partially processor-implemented, with a particular processor or processors being an example of hardware. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented components. Moreover, the one or more processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines including processors), with these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., an API). The performance of certain of the operations may be distributed among the processors, not only residing within a single machine, but deployed across a number of machines. In some examples, the processors or processor-implemented components may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other examples, the processors or processor-implemented components may be distributed across a number of geographic locations.
“Computer-readable storage medium” refers, for example, to both machine-storage media and transmission media. Thus, the terms include both storage devices/media and carrier waves/modulated data signals. The terms “machine-readable medium,” “computer-readable medium” and “device-readable medium” mean the same thing and may be used interchangeably in this disclosure. “Ephemeral message” refers, for example, to a message that is accessible for a time-limited duration. An ephemeral message may be a text, an image, a video and the like. The access time for the ephemeral message may be set by the message sender. Alternatively, the access time may be a default setting or a setting specified by the recipient. Regardless of the setting technique, the message is transitory.
“Machine storage medium” refers, for example, to a single or multiple storage devices and media (e.g., a centralized or distributed database, and associated caches and servers) that store executable instructions, routines and data. The term shall accordingly be taken to include, but not be limited to, solid-state memories, and optical and magnetic media, including memory internal or external to processors. Specific examples of machine-storage media, computer-storage media and device-storage media include non-volatile memory, including by way of example semiconductor memory devices, e.g., erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), FPGA, and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks The terms “machine-storage medium,” “device-storage medium,” “computer-storage medium” mean the same thing and may be used interchangeably in this disclosure.
The terms “machine-storage media,” “computer-storage media,” and “device-storage media” specifically exclude carrier waves, modulated data signals, and other such media, at least some of which are covered under the term “signal medium.” “Non-transitory computer-readable storage medium” refers, for example, to a tangible medium that is capable of storing, encoding, or carrying the instructions for execution by a machine. “Signal medium” refers, for example, to any intangible medium that is capable of storing, encoding, or carrying the instructions for execution by a machine and includes digital or analog communications signals or other intangible media to facilitate communication of software or data. The term “signal medium” shall be taken to include any form of a modulated data signal, carrier wave, and so forth. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a matter as to encode information in the signal. The terms “transmission medium” and “signal medium” mean the same thing and may be used interchangeably in this disclosure.
“User device” refers, for example, to a device accessed, controlled or owned by a user and with which the user interacts perform an action, or an interaction with other users or computer systems. “Carrier signal” refers to any intangible medium that is capable of storing, encoding, or carrying instructions for execution by the machine and includes digital or analog communications signals or other intangible media to facilitate communication of such instructions. Instructions may be transmitted or received over a network using a transmission medium via a network interface device. “Client device” refers to any machine that interfaces to a communications network to obtain resources from one or more server systems or other client devices. A client device may be, but is not limited to, a mobile phone, desktop computer, laptop, portable digital assistants (PDAs), smartphones, tablets, ultrabooks, netbooks, laptops, multi-processor systems, microprocessor-based or programmable consumer electronics, game consoles, set-top boxes, or any other communication device that a user may use to access a network.
“Communication network” refers to one or more portions of a network that may be an ad hoc network, an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a wireless WAN (WWAN), a metropolitan area network (MAN), the Internet, a portion of the Internet, a portion of the Public Switched Telephone Network (PSTN), a plain old telephone service (POTS) network, a cellular telephone network, a wireless network, a Wi-Fi® network, another type of network, or a combination of two or more such networks. For example, a network or a portion of a network may include a wireless or cellular network, and the coupling may be a Code Division Multiple Access (CDMA) connection, a Global System for Mobile communications (GSM) connection, or other types of cellular or wireless coupling. In this example, the coupling may implement any of a variety of types of data transfer technology, such as Single Carrier Radio Transmission Technology (1×RTT), Evolution-Data Optimized (EVDO) technology, General Packet Radio Service (GPRS) technology, Enhanced Data rates for GSM Evolution (EDGE) technology, third Generation Partnership Project (3GPP) including 3G, fourth-generation wireless (4G) networks, Universal Mobile Telecommunications System (UMTS), High Speed Packet Access (HSPA), Worldwide Interoperability for Microwave Access (WiMAX), Long Term Evolution (LTE) standard, others defined by various standard-setting organizations, other long-range protocols, or other data transfer technology.
Components may constitute either software components (e.g., code embodied on a machine-readable medium) or hardware components. A “hardware component” is a tangible unit capable of performing certain operations and may be configured or arranged in a certain physical manner. In various examples, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware components of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware component that operates to perform certain operations as described herein.
A hardware component may also be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware component may include dedicated circuitry or logic that is permanently configured to perform certain operations. A hardware component may be a special-purpose processor, such as a field-programmable gate array (FPGA) or an ASIC. A hardware component may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, a hardware component may include software executed by a general-purpose processor or other programmable processor.
