[0020] Messaging systems typically allow users to exchange content items (e.g., messages, images, and / or videos) with each other in a message thread. Messaging systems may implement various functions for modifying or otherwise supplementing image data captured by a device camera for inclusion in a message. Examples of such functions include: applying augmented reality content to image data; selecting an audio track to accompany the image data; and enabling different camera modes for image capture (e.g., timer mode, slow motion mode, etc.).

[0021] The disclosed embodiments provide a messaging system with shortcuts, in which each shortcut corresponds to a combination of applying separate functions to captured image data. The shortcuts allow an end user to apply a combination of separate functions to image data via a single gesture (e.g., a tap or press). Icons that activate shortcuts can be displayed within different user interfaces of the messaging application, including a camera-centric interface (which displays all available shortcuts), a scan results interface (which displays shortcuts related to objects detected via a scan operation), and an interface that displays media content items (where the associated shortcuts are represented by icons).

[0022] By generating, maintaining and storing shortcuts for combining separate functions, the amount of user input normally required to perform separate functions can be reduced. In addition, the corresponding user interface with shortcuts provides an attractive user experience.

[0023] Figure 1 1 is a block diagram illustrating an example messaging system 100 for exchanging data (e.g., messages and associated content) over a network. The messaging system 100 includes multiple instances of client devices 102, each instance hosting several applications, including a messaging client 104 and other applications 106. Each messaging client 104 is communicatively coupled to other instances of the messaging client 104 (e.g., hosted on respective other client devices 102), a messaging server system 108, and a third-party server 110 via a network 112 (e.g., the Internet). The messaging client 104 may also communicate with the locally hosted application 106 using an application program interface (API).

[0024] The message clients 104 are able to communicate and exchange data with other message clients 104 and message server systems 108 via the network 112. The data exchanged between the message clients 104 and between the message clients 104 and the message server systems 108 include functions (e.g., commands for activating functions) and payload data (e.g., text, audio, video, or other multimedia data).

[0025] The message server system 108 provides server-side functionality to a particular message client 104 via the network 112. Although certain functions of the message system 100 are described herein as being performed by the message client 104 or by the message server system 108, whether certain functions are located within the message client 104 or within the message server system 108 may be a design choice. For example, it may be technically preferred to initially deploy certain technologies and functions within the message server system 108, but later migrate the technologies and functions to the message client 104 if the client device 102 has sufficient processing power.

[0026] The message server system 108 supports various services and operations provided to the message clients 104. Such operations include sending data to the message clients 104, receiving data from the message clients 104, and processing data generated by the message clients 104. As examples, the data may include message content, client device information, geolocation information, media enhancements and overlays, message content persistence conditions, social network information, and live event information. The data exchange within the message system 100 is activated and controlled by functions available via the user interface (UI) of the message client 104.

[0027] Turning now specifically to the message server system 108, an application program interface (API) server 116 is coupled to the application server 114 and provides a programming interface to the application server 114. The application server 114 is communicatively coupled to a database server 120, which facilitates access to a database 126 that stores data associated with messages processed by the application server 114. Similarly, a web server 128 is coupled to the application server 114 and provides a web-based interface to the application server 114. To this end, the web server 128 handles incoming network requests via the Hypertext Transfer Protocol (HTTP) and several other related protocols.

[0028] The application program interface (API) server 116 receives and sends message data (e.g., commands and message payloads) between the client device 102 and the application server 114. Specifically, the application program interface (API) server 116 provides a set of interfaces (e.g., routines and protocols) that can be called or queried by the message client 104 to activate the functions of the application server 114. The application program interface (API) server 116 exposes various functions supported by the application server 114, including: account registration; login function; sending messages from a particular message client 104 to another message client 104 via the application server 114; sending media files (e.g., images or videos) from the message client 104 to the message server 118 and for possible access by another message client 104; setting up a collection of media data (e.g., a story); retrieving a friend list of the user of the client device 102; retrieving such a collection; retrieving messages and content; adding and removing entities (e.g., friends) from an entity graph (e.g., a social graph); locating friends within a social graph; and opening application events (e.g., related to the message client 104).

[0029] The application server 114 hosts several server applications and subsystems, including, for example, a message server 118, an image processing server 122, and a social network server 124. The message server 118 implements several message processing techniques and functions, particularly those related to the aggregation and other processing of content (e.g., text and multimedia content) included in messages received from multiple instances of the message client 104. As will be described in further detail, text and media content from multiple sources can be aggregated into content collections (e.g., referred to as stories or galleries). These collections are then made available to the message client 104. Given the hardware requirements for other processor and memory intensive data processing, other processor and memory intensive data processing can also be performed on the server side by the message server 118.

[0030] The application server 114 also includes an image processing server 122 that is dedicated to performing various image processing operations, typically on images or videos within the payload of messages sent from or received at the message server 118 .

[0031] The social network server 124 supports various social networking functions and services and makes them available to the message server 118. To this end, the social network server 124 maintains and accesses the entity graph 304 (e.g., Figure 3 Examples of functions and services supported by the social network server 124 include identifying other users of the messaging system 100 that have a relationship with a particular user or that the particular user is "following," and also identifying interests and other entities of a particular user.

[0032] Returning to the message client 104, the features and functions of the external resource (e.g., application 106 or applet) are available to the user via the interface of the message client 104. In this context, "external" refers to the fact that the application 106 or applet is outside the message client 104. External resources are usually provided by a third party, but can also be provided by the creator or provider of the message client 104. The message client 104 receives a user selection of an option to launch or access the features of such an external resource. The external resource can be an application 106 (e.g., a "local app") installed on the client device 102, or a small-scale version of the application (e.g., a "mini program") hosted on the client device 102 or away from the client device 102 (e.g., on a third-party server 110). The small-scale version of the application includes a subset of the features and functions of the application (e.g., a full-scale, local version of the application) and is implemented using a markup language document. In one example, the small-scale version of the application (e.g., a "mini program") is a web-based markup language version of the application and is embedded in the message client 104. In addition to using markup language documents (eg, .*ml files), applets may incorporate scripting languages ​​(eg, .*js files or .json files) and style sheets (eg, .*ss files).

[0033] In response to receiving a user selection of an option to launch or access a feature of an external resource, the message client 104 determines whether the selected external resource is a web-based external resource or a locally installed application 106. In some cases, the application 106 locally installed on the client device 102 can be independent of the message client 104 and launched separately from the message client 104, such as by selecting an icon corresponding to the application 106 on a home screen of the client device 102. A small-scale version of such an application can be launched or accessed via the message client 104, and in some examples, all portions of the small-scale application cannot be accessed outside the message client 104 or limited portions of the small-scale application can be accessed outside the message client 104. The small-scale application can be launched by the message client 104 receiving a markup language document associated with the small-scale application, such as from a third-party server 110, and processing such a document.

[0034] In response to determining that the external resource is a locally installed application 106, the message client 104 instructs the client device 102 to launch the external resource by executing the locally stored code corresponding to the external resource. In response to determining that the external resource is a web-based resource, the message client 104 communicates with the third-party server 110 (for example) to obtain a markup language document corresponding to the selected external resource. The message client 104 then processes the obtained markup language document to present the web-based external resource within the user interface of the message client 104.

[0035] The message client 104 may notify the user of the client device 102 or other users (e.g., "friends") associated with such a user of activities occurring in one or more external resources. For example, the message client 104 may provide a notification related to the current or recent use of an external resource by one or more members of a group of users to a participant in a conversation (e.g., a chat session) in the message client 104. One or more users may be invited to join an active external resource or to launch an external resource that was recently used but is currently inactive (in the group of friends). The external resource may provide the participants in the conversation, each using a corresponding message client 104, with the ability to share items, conditions, states, or locations in an external resource with one or more members of a group of users in a chat session. The shared item may be an interactive chat card that members of the chat may interact with, for example, to launch a corresponding external resource, view specific information within an external resource, or bring members of the chat to a specific location or state within an external resource. Within a given external resource, a response message may be sent to a user on the message client 104. The external resource may selectively include different media items in the response based on the current context of the external resource.

[0036] The messaging client 104 may present a list of available external resources (e.g., applications 106 or applets) to the user to launch or access a given external resource. The list may be presented in the form of a context-sensitive menu. For example, icons representing different applications 106 (or applets) may vary based on how the menu is launched by the user (e.g., from a conversational interface or from a non-conversational interface).

[0037] Figure 2 1 is a block diagram showing further details about the messaging system 100 according to some examples. Specifically, the messaging system 100 is shown to include a messaging client 104 and an application server 114. The messaging system 100 contains several subsystems that are supported on the client side by the messaging client 104 and on the server side by the application server 114. These subsystems include, for example, a transient timer system 202, a collection management system 204, an enhancement system 208, a map system 212, an external resource system 214, a camera mode system 216, an audio track system 218, and a shortcut system 220.

[0038] The transient timer system 202 is responsible for implementing temporary or time-limited access to content by the message client 104 and the message server 118. The transient timer system 202 includes a number of timers that selectively enable access (e.g., for presentation and display) of messages and associated content via the message client 104 based on duration and display parameters associated with a message or a collection of messages (e.g., a story). Additional details regarding the operation of the transient timer system 202 are provided below.

[0039] The collection management system 204 is responsible for managing collections or collections of media (e.g., collections of text, image video, and audio data). Collections of content (e.g., messages, including images, videos, text, and audio) can be organized into "event galleries" or "event stories." Such collections can be made available for a specified time period (e.g., the duration of the event to which the content relates). For example, content related to a concert can be made available as a "story" for the duration of the concert. The collection management system 204 can also be responsible for publishing an icon that provides notification of the existence of a particular collection to the user interface of the messaging client 104.

[0040] In addition, the collection management system 204 includes a curation interface 206 that allows a collection manager to manage and curate a particular collection of content. For example, the curation interface 206 enables an event organizer to curate a collection of content related to a particular event (e.g., to delete inappropriate content or redundant messages). In addition, the collection management system 204 uses machine vision (or image recognition technology) and content rules to automatically curate content collections. In some examples, compensation may be paid to users to include user-generated content in a collection. In such a case, the collection management system 204 operates to automatically pay such users for use of their content.

[0041] The enhancement system 208 provides various functions that enable a user to enhance (e.g., annotate or otherwise modify or edit) media content associated with a message. For example, the enhancement system 208 provides functions related to generating and publishing media overlays for messages processed by the messaging system 100. The enhancement system 208 is operable to provide media overlays or enhancements (e.g., image filters) to the messaging client 104 based on the geographic location of the client device 102. In another example, the enhancement system 208 is operable to provide media overlays to the messaging client 104 based on other information such as social network information of the user of the client device 102. The media overlay can include audio and visual content and visual effects. Examples of audio and visual content include pictures, text, logos, animations, and sound effects. Examples of visual effects include color overlays. Audio and visual content or visual effects can be applied to media content items (e.g., photos) at the client device 102. For example, the media overlay can include text or images that can be superimposed on top of a photo taken by the client device 102. In another example, the media overlay includes a location identifier (e.g., Venice Beach) overlay, the name of a live event, or a business name (e.g., Beach Cafe) overlay. In another example, the augmentation system 208 uses the geolocation of the client device 102 to identify a media overlay that includes the name of the business at the geolocation of the client device 102. The media overlay may include other tags associated with the business. The media overlay may be stored in the database 126 and accessed through the database server 120.

[0042] In some examples, the enhancement system 208 provides a user-based publishing platform that enables a user to select a geolocation on a map and upload content associated with the selected geolocation. The user can also specify an environment in which a particular media overlay should be provided to other users. The enhancement system 208 generates a media overlay including the uploaded content and associates the uploaded content with the selected geolocation.

[0043] In other examples, the enhancement system 208 provides a merchant-based publishing platform that enables merchants to select specific media overlays associated with a geographic location via a bidding process. For example, the enhancement system 208 associates the media overlays of the highest bidding merchant with the corresponding geographic location for a predefined amount of time.

[0044] In other examples, such as the following Figure 3As discussed, the augmentation system 208 enables presentation of augmented reality content in association with an image or video captured by a camera of the client device 102. The augmentation system 208 may implement or otherwise access augmented reality content items (e.g., corresponding to an application lens or augmented reality experience) to provide real-time special effects and / or sounds that may be added to the image or video.

[0045] In one or more embodiments, augmentation system 208 includes or otherwise accesses object detection system 210. For example, object detection system 210 may be included within augmentation system 208 (e.g., Figure 2 ), or may be separate and accessible by enhancement system 208.

[0046] The object detection system 210 provides various object detection functions in the context of the messaging system 100. The object detection system 210 may employ one or more object classifiers to identify objects depicted in a captured image. The image may correspond to a live video feed captured by a camera (e.g., a rear camera or a front camera) of the client device 102. Alternatively or additionally, the image may correspond to an image (e.g., a photo) stored in association with a user of the client device 102 (e.g., in a photo library).

[0047] In one or more embodiments, the object detection system 210 is configured to implement or otherwise access an object recognition algorithm (e.g., including a machine learning algorithm) that is configured to scan a captured image and detect / track the movement of objects within the image. Detectable objects within an image include, by way of non-limiting example, human faces, parts of a human body, animals and parts thereof, landscapes, natural objects, inanimate objects (e.g., clothing, chairs, books, cars, buildings, other structures), illustrations of objects (e.g., on posters and / or flyers), text-based objects, equation-based objects, and the like.

[0048] In addition, the object detection system 210 is configured to determine or otherwise access properties of the object. For a particular object, the object detection system 210 can determine or retrieve properties such as name / type, genre, color, size, shape, texture, environmental factors (e.g., geolocation, time, weather), and / or other supplemental information (e.g., song title / artist for an object corresponding to media).

[0049] With respect to environmental factors, the object detection system 210 may receive information from the messaging client 104 to identify weather, geolocation, time, etc., around the client device 102 (e.g., via device sensors). The object detection system 210 may rank the retrieved attributes based on relevance, for example, based on the association of the attributes with one or more environmental factors. Other machine learning techniques may be employed to select and rank the retrieved attributes. The object detection system 210 may select an object associated with the highest-ranked attribute from a list of objects detected in the captured image, and may send an indication of the selected object to the messaging client 104. Alternatively or additionally, the object detection system 210 may cause one or more attributes (e.g., name / type) of each detected object and / or an indication of the ranking of the attributes to be transmitted to the messaging client 104.

[0050] In one or more embodiments, the object detection system 210 determines that one of the attributes corresponds to a keyword that has been sponsored by a third party. For example, a third party may sponsor certain keywords or pay for certain keywords to be ranked higher than other keywords. In response to determining that a given attribute corresponds to a sponsored keyword, the object detection system 210 may rank the attribute higher relative to the other attributes.

[0051] The mapping system 212 provides various geolocation functions and supports the presentation of map-based media content and messages by the messaging client 104. For example, the mapping system 212 enables the display of a user icon or avatar (e.g., stored in the profile data 302) on a map to indicate the current or past locations of the user's "friends" and media content (e.g., a collection of messages including photos and videos) generated by such friends in the context of the map. For example, a message posted by a user to the messaging system 100 from a particular geolocation can be displayed to the "friends" of a particular user on the mapping interface of the messaging client 104 within the context of that particular location on the map. The user can also share his or her location and status information with other users of the messaging system 100 (e.g., using an appropriate status avatar) via the messaging client 104, where the location and status information is similarly displayed to selected users within the context of the mapping interface of the messaging client 104.

[0052] The external resource system 214 provides an interface for the message client 104 to communicate with a remote server (e.g., a third-party server 110) to launch or access external resources, i.e., applications or applets. Each third-party server 110 hosts, for example, an application or a small-scale version of an application based on a markup language (e.g., HTML5) (e.g., a game application, a utility application, a payment application, or a ride-sharing application). The message client 104 can launch a web-based resource (e.g., an application) by accessing an HTML5 file from a third-party server 110 associated with a web-based resource. In some examples, the application hosted by the third-party server 110 is programmed in JavaScript using a software development kit (SDK) provided by the message server 118. The SDK includes an application programming interface (API) having functions that can be called or activated by a web-based application. In some examples, the message server 118 includes a JavaScript library that provides a given external resource access to certain user data of the message client 104. HTML5 is used as an example technology for programming games, but applications and resources programmed based on other technologies can be used.

[0053] To integrate the functionality of the SDK into the web-based resource, the SDK is downloaded by the third-party server 110 from the message server 118, or received by the third-party server 110 in other ways. Once downloaded or received, the SDK is included as part of the application code of the web-based external resource. The code of the web-based resource can then call or activate certain functions of the SDK to integrate the features of the message client 104 into the web-based resource.

[0054] The SDK stored on the message server 118 effectively provides a bridge between external resources (e.g., applications 106 or applet) and the message client 104. This provides users with a seamless experience of communicating with other users on the message client 104 while retaining the look and feel of the message client 104. In order to bridge the communication between the external resources and the message client 104, in some examples, the SDK facilitates the communication between the third-party server 110 and the message client 104. In some examples, the WebViewJavaScriptBridge running on the client device 102 establishes two one-way communication channels between the external resources and the message client 104. Messages are sent asynchronously via these communication channels between the external resources and the message client 104. Each SDK function activation is sent as a message and a callback. Each SDK function is implemented by constructing a unique callback identifier and sending a message with the callback identifier.

[0055] By using the SDK, not all information from the message client 104 is shared with the third-party server 110. The SDK limits which information is shared based on the needs of the external resource. In some examples, each third-party server 110 provides an HTML5 file corresponding to a web-based external resource to the message server 118. The message server 118 can add a visual representation (e.g., box art or other graphics) of the web-based external resource in the message client 104. Once the user selects the visual representation or instructs the message client 104 to access the features of the web-based external resource through the GUI of the message client 104, the message client 104 obtains the HTML5 file and instantiates the resources required for accessing the features of the web-based external resource.

[0056] The message client 104 presents a graphical user interface (e.g., a login page or title screen) for an external resource. During, before, or after presenting the login page or title screen, the message client 104 determines whether the external resource launched has been previously authorized to access the user data of the message client 104. In response to determining that the launched external resource has previously been authorized to access the user data of the message client 104, the message client 104 presents another graphical user interface of the external resource including the functions and features of the external resource. In response to determining that the launched external resource has not previously been authorized to access the user data of the message client 104, after a threshold time period (e.g., 3 seconds) of displaying the login page or title screen of the external resource, the message client 104 slides a menu for authorizing the external resource to access the user data (e.g., animating the menu to emerge from the bottom of the screen to the middle or other part of the screen). 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 the acceptance option, the message client 104 adds the external resource to the list of authorized external resources and enables the external resource to access the user data from the message client 104. In some examples, messaging client 104 authorizes external resources to access user data in accordance with the OAuth 2 framework.

[0057] The messaging client 104 controls the type of user data shared with the external resource based on the type of external resource that is authorized. For example, an external resource including a full-scale application (e.g., application 106) is provided with access to a first type of user data (e.g., only a two-dimensional avatar of a user with or without different avatar characteristics). As another example, an external resource including a small-scale version of an application (e.g., a web-based version of the application) is provided with access to a second type of user data (e.g., payment information, a two-dimensional avatar of a user, a three-dimensional avatar of a user, and avatars with various avatar characteristics). Avatar characteristics include different ways to customize the look and feel of an avatar (e.g., different poses, facial features, clothing, etc.).

[0058] The camera mode system 216 implements various functions for providing different camera modes within the context of the messaging system 100. For example, the camera mode system 216 provides one or more of a timeline mode, a timer mode, and a slow motion mode. The timeline mode is a default setting that a user can select to capture a series of photos / video clips (or segments) to generate a media content item (e.g., based on multiple taps and / or a hold and press gesture of a capture button), rather than capturing a single photo / video clip to generate a media content item (e.g., based on a single tap or a hold and press gesture of a capture button). The timer mode is a default setting that a user can select to set a time to start video capture (e.g., after 5 seconds, 10 seconds, etc.), rather than immediately between video captures (e.g., in response to a tap or a hold and press gesture). The slow motion mode is a default setting that a user can select to capture video in slow motion, rather than capturing video at a regular (e.g., non-slow motion) time.

[0059] The audio track system 218 implements various functions for adding an audio track to a captured video (or captured image) for generating a media content item. For example, the audio track system 218 enables access to a directory of available audio tracks, presents available audio tracks for user selection, and combines the selected audio track with a captured video or image to generate a media content item. In one or more embodiments, the directory of available audio tracks is maintained by a third-party server (e.g., corresponding to one of the third-party servers 110). For example, the audio track system 218 is configured to access (e.g., download and / or stream) audio tracks based on a licensing arrangement between the messaging system 100 and the third-party server. In one or more embodiments, the audio track system 218 is also configured to access identification information for a given audio track, such as the title (e.g., song name), artist, genre, etc. of the audio track.

[0060] The shortcut system 220 implements various functions for generating, maintaining, and storing shortcuts for the messaging system 100. As described herein, a shortcut represents a combination of separate functions applied in association with capturing an image. Examples of such separate functions correspond to applying an augmented reality content item (e.g., in accordance with the augmentation system 208), applying a camera mode (e.g., in accordance with the camera mode system 216), and / or applying an audio track (e.g., in accordance with the audio track system 218) for capturing image data (e.g., a photo, a live video feed). The combination of separate functions corresponds to applying two or more of an augmented reality content item, a camera mode, or an audio track for capturing an image. Note that other separate functions may be used instead of or in addition to the augmented reality content item, the camera mode, and the audio track as part of the combination for a shortcut.

[0061] Figure 3 is a schematic diagram illustrating a data structure 300 that may be stored in database 126 of message server system 108 according to some examples. Although the contents of database 126 are shown as including several tables, it will be appreciated that data may be stored in other types of data structures (eg, object-oriented databases).

[0062] Database 126 includes message data stored in message table 306. For any particular message, the message data includes at least message sender data, message recipient (or receiver) data, and payload. Figure 4 Additional details regarding information that may be included in a message and included in the message data stored in message table 306 are described.

[0063] The entity table 308 stores entity data and is linked (e.g., by reference) to the entity graph 304 and the profile data 302. The entities for which records are maintained within the entity table 308 may include individuals, corporate entities, organizations, objects, places, events, etc. Regardless of the entity type, any entity about which the message server system 108 stores data may be an identified entity. Each entity is provided with a unique identifier as well as an entity type identifier (not shown).

[0064] The entity graph 304 stores information about the relationships and associations between entities. As examples only, such relationships may be social relationships, professional relationships (e.g., working in a common company or organization) based on interests or based on activities.

[0065] Profile data 302 stores multiple types of profile data about a particular entity. Based on the privacy settings specified by the particular entity, profile data 302 can be selectively used and presented to other users of the messaging system 100. In the case where the entity is a person, profile data 302 includes, for example, a user name, phone number, address, settings (e.g., notification and privacy settings), and an avatar representation (or a collection of such avatar representations) selected by the user. The particular user can then selectively include one or more of these avatar representations in the content of messages transmitted via the messaging system 100 and in a map interface displayed to other users by the messaging client 104. The collection of avatar representations can include a "status avatar" that presents a graphical representation of a state or activity that a user can select to communicate at a particular time.

[0066] 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 related to the group (eg, notifications).

[0067] Database 126 also stores enhancement data, such as overlays or filters, in enhancement table 310. Enhancement data is associated with and applied to videos (for which data is stored in video table 314) and images (for which data is stored in image table 316).

[0068] In one example, a filter is an overlay displayed as an overlay on an image or video during presentation to a recipient user. The filter can be of various types, including a user-selected filter from a set of filters presented to a sending user by the message client 104 when the sending user is composing a message. Other types of filters include geolocation filters (also referred to as geofilters), which can be presented to a sending user based on geolocation. For example, a geolocation filter specific to a nearby or specific location can be presented by the message client 104 within a user interface based on geolocation information determined by a global positioning system (GPS) unit of the client device 102.

[0069] Another type of filter is a data filter, which can be selectively presented to the sending user by the message client 104 based on other input or information collected by the client device 102 during the message creation process. Examples of data filters include the current temperature at a particular location, the current speed the sending user is traveling, the battery life of the client device 102, or the current time.

[0070] Other augmented data that may be stored in the image table 316 include augmented reality content items (eg, corresponding to an application lens or augmented reality experience). The augmented reality content items may provide real-time special effects and / or sounds that may be added to an image or video.

[0071] As described above, augmented data includes augmented reality content items, overlays, image transformations, AR images, and similar items that refer to modifications that can be applied to image data (e.g., videos or images). This includes real-time modifications that are modified using a device sensor (e.g., one or more cameras) of the client device 102 to capture an image and then modify the image using the modification when the image is displayed on the screen of the client device 102. This also includes modifications to stored content (e.g., video clips in a gallery that can be modified). For example, in a client device 102 that accesses multiple augmented reality content items, a user can use a single video clip with multiple augmented reality content items to see how different augmented reality content items will modify the stored clips. For example, by selecting different augmented reality content items for the content, multiple augmented reality content items that apply different pseudo-random movement models can be applied to the same content. Similarly, real-time video capture can be used with the modifications shown to show how the video image currently captured by the sensor of the client device 102 will modify the captured data. Such data may simply be displayed on the screen without being stored in memory, or content captured by the device sensors may be recorded and stored in memory with or without modification (or both). In some systems, a preview feature may show how different augmented reality content items will look in different windows in the display simultaneously. This may, for example, enable viewing of multiple windows with different pseudo-random animations on the display simultaneously.

[0072] Thus, data and various systems using augmented reality content items or other such transformation systems that modify content using such data may involve detection of objects (e.g., faces, hands, bodies, cats, dogs, surfaces, objects, etc.) in video frames, tracking of such objects as they leave, enter, and move around the field of view, and modification or transformation of such objects as they are tracked. In various examples, different methods for implementing such transformations may be used. Some examples may involve: generating a three-dimensional mesh model of one or more objects; and using transformations of the model and animated textures within a video to implement the transformations. In other examples, tracking of points on an object may be used to place an image or texture (which may be two-dimensional or three-dimensional) at the tracked location. In yet other examples, neural network analysis of a video frame may be used to place an image, model, or texture in content (e.g., an image or video frame). Thus, augmented reality content items refer both to images, models, and textures used to create transformations in content, and to additional modeling and analysis information required to implement such transformations using object detection, tracking, and placement.

[0073] Real-time video processing can be performed using any kind of video data (e.g., video streams, video files, etc.) stored in the memory of any kind of computerized system. For example, a user can load video files and store them in the memory of the device, or a sensor of the device can be used to generate a video stream. In addition, any object, such as a human face and parts of a human body, an animal, or a non-living thing (e.g., a chair, a car, or other objects) can be processed using computer animation models.

[0074] In some examples, when a specific modification is selected together with the content to be transformed, the element to be transformed is identified by the computing device, and then if the element to be transformed is present in the frame of the video, the element to be transformed is detected and tracked. The element of the object is modified according to the request for modification, so the frame of the video stream is transformed. The transformation of the frame of the video stream can be performed by different methods for different types of transformations. For example, for the transformation of the frame that mainly involves changing the form of the element of the object, the characteristic points of each element of the object are calculated (for example, using active shape model (ASM) or other known methods). Then, for each element of at least one element of the object, a grid based on the characteristic points is generated. The grid is used for the subsequent stage of tracking the element of the object in the video stream. In the process of tracking, the grid mentioned for each element is aligned with the position of each element. Then, additional points are generated on the grid. A first group of first points is generated for each element based on the request for modification, and a group of second points is generated for each element based on the group of first points and the modification request. Then, the frame of the video stream can be transformed by modifying the element of the object based on a group of first points and a group of second points and a grid. In such a method, the background of the modified object may also be changed or distorted by tracking and modifying the background of the modified object.

[0075] In some examples, a transformation that changes some areas of an object using elements of an object can be performed by calculating characteristic points for each element of the object and generating a grid based on the calculated characteristic points. Points are generated on the grid, and then various areas are generated based on these points. Then, the elements of the object are tracked by aligning the area of ​​each element with the position of each element of at least one element, and the properties of the area can be modified based on the modification request, thereby transforming the frame of the video stream. Depending on the specific modification request, the properties of the mentioned area can be transformed in different ways. Such modifications may involve: changing the color of the area; removing at least some parts of the area from the frame of the video stream; including one or more new objects into the area based on the request for modification; and modifying or distorting the elements of the area or object. In various examples, any combination of such modifications or other similar modifications may be used. For some models to be animated, some characteristic points can be selected as control points for determining the entire state space of options for model animation.

[0076] In some examples of computer animation models that use face detection to transform image data, faces are detected on an image using a specific face detection algorithm (e.g., Viola-Jones). An active shape model (ASM) algorithm is then applied to the face region of the image to detect facial feature reference points.

[0077] Other methods and algorithms suitable for face detection can be used. For example, in some examples, landmarks are used to locate features, which represent distinguishable points that exist in most of the images considered. For example, for facial landmarks, the location of the left pupil can be used. If the initial landmark is not recognizable (for example, if the person has an eye mask), secondary landmarks can be used. Such a landmark identification process can be used for any such object. In some examples, a set of landmarks forms a shape. The coordinates of the points in the shape can be used to represent the shape as a vector. One shape is aligned with another shape using a similarity transformation (allowing translation, scaling, and rotation) that minimizes the average Euclidean distance between the shape points. The mean shape is the mean of the aligned training shapes.

[0078] In some examples, the landmark search begins with a mean shape that is aligned with the position and size of the face determined by a global face detector. Such a search then repeats the steps of proposing tentative shapes by adjusting the positions of the shape points via template matching of the image texture around each point, and then conforming the tentative shapes to a global shape model until convergence occurs. In some systems, individual template matching is unreliable, and the shape model pools the results of weak template matches to form a stronger overall classifier. The entire search is repeated at each level of the image pyramid from coarse to fine resolution.

[0079] The transformation system can capture an image or video stream on a client device (e.g., client device 102) and perform complex image manipulations locally on the client device 102 while maintaining an appropriate user experience, computational time, and power consumption. Complex image manipulations can include size and shape changes, emotion transformations (e.g., changing a face from a frown to a smile), state transitions (e.g., aging a subject, reducing apparent age, changing gender), style transfer, application of graphical elements, and any other suitable image or video manipulations enabled by a convolutional neural network that has been configured to execute efficiently on the client device 102.

[0080] In some examples, a computer animation model for transforming image data can be used by a system in which a user can capture an image or video stream of the user (e.g., a selfie) using a client device 102 having a neural network that operates as part of a messaging client 104 operating on the client device 102. A transformation system operating within the messaging client 104 determines the presence of a face in the image or video stream and provides a modification icon associated with the computer animation model to transform the image data, or the computer animation model can be presented in association with an interface described herein. The modification icon includes the following changes, which can be the basis for modifying the face of the user within the image or video stream as part of the modification operation. Once the modification icon is selected, the transformation system initiates a process of transforming the image of the user to reflect the selected modification icon (e.g., generating a smiley face on the user). Once the image or video stream is captured and the specified modification is selected, the modified image or video stream can be presented in a graphical user interface displayed on the client device 102. The transformation system can implement a complex convolutional neural network on a portion of the image or video stream to generate and apply the selected modification. That is, a user can capture an image or video stream and once a modification icon is selected, the modification result is presented in real time or near real time. In addition, when the video stream is being captured, the modification can be persistent and the selected modification icon remains toggled. Machine-taught neural networks can be used to implement such modifications.

[0081] The graphical user interface presenting the modifications performed by the transformation system can supply the user with additional interactive options. Such options can be based on the interface for initiating content capture and selecting a specific computer animation model (e.g., initiated from a content creator user interface). In various examples, the modifications can be persistent after the modification icon is initially selected. The user can switch to turn the modification on or off by tapping or otherwise selecting the face modified by the transformation system, and store it for later viewing or browsing to other areas of the imaging application. In the case of multiple faces modified by the transformation system, the user can globally switch to turn the modification on or off by tapping or selecting a single face modified and displayed within the graphical user interface. In some examples, each face in a group of multiple faces can be modified individually, or such modifications can be switched individually by tapping or selecting each face or a series of each face displayed within the graphical user interface.

[0082] The story table 312 stores data about a collection of messages and associated image, video or audio data that are compiled into a collection (e.g., a story or gallery). The creation of a particular collection can be initiated by a particular user (e.g., each user whose record is maintained in the entity table 308). A user can create a "personal story" in the form of a collection of content that has been created and sent / broadcasted by the user. To this end, the user interface of the messaging client 104 may include a user-selectable icon to enable the sending user to add specific content to his or her personal story.

[0083] A collection may also constitute a "live story" that is a collection of content from multiple users, 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 who are at a co-located event at a particular time may be presented with an option, for example, via a user interface of a messaging client 104, to contribute content to a particular live story. Live stories may be identified to a user by the messaging client 104 based on his or her location. The end result is a "live story" told from a community perspective.

[0084] Another type of content collection is called a "location story" that enables users whose client devices 102 are located within a specific geographic location (e.g., on a college or university campus) to contribute to a specific collection. In some examples, contributions to location stories may require secondary authentication to verify that the end user belongs to a specific organization or other entity (e.g., is a student on a university campus).

[0085] As mentioned above, the video table 314 stores video data, which in one example is associated with a message whose record is maintained within the message table 306. Similarly, the image table 316 stores image data associated with a message whose message data is stored in the entity table 308. The entity table 308 may associate various enhancements from the enhancement table 310 with the various images and videos stored in the image table 316 and the video table 314.

[0086] The shortcut table 318 stores a collection of available shortcuts for applying to capturing an image. The shortcut system 220 is configured to generate a representation of a shortcut and store it in the shortcut table 318. For each shortcut, the shortcut table 318 stores a combination of the shortcut name, the function of the shortcut (e.g., two or more of an augmented reality content item, a camera mode, or an audio track) and a corresponding indication of an available preview of the shortcut. For example, the preview corresponds to a sample media content item for applying a shortcut to another captured image (e.g., another user). In addition, the shortcut table 318 is configured to store object properties (e.g., as metadata) in association with the shortcut. For example, the object properties can indicate one or more of the object type, the name, color, size, and / or shape associated with a particular shortcut.

[0087] Figure 4 is a schematic diagram illustrating the structure of a message 400 according to some examples, the message 400 being generated by a message client 104 for transmission to another message client 104 or a message server 118. The content of a particular message 400 is used to populate a message table 306 stored in a database 126 accessible by a message server 118. Similarly, the content of the message 400 is stored in memory as "in-transit" or "in-flight" data of a client device 102 or an application server 114. The message 400 is shown to include the following example components:

[0088] Message identifier 402 : a unique identifier that identifies the message 400 .

[0089] Message text payload 404 : Text to be generated by a user via the user interface of the client device 102 and included in the message 400 .

[0090] Message image payload 406 : Image data captured by a camera component of the client device 102 or retrieved from a memory component of the client device 102 and included in the message 400 . Image data for a message 400 sent or received may be stored in the image table 316 .

[0091] Message video payload 408 : Video data captured by the camera component or retrieved from the memory component of the client device 102 and included in the message 400 . The video data for a message 400 sent or received may be stored in the video table 314 .

[0092] Message audio payload 410 : audio data captured by a microphone or retrieved from a memory component of the client device 102 and included in the message 400 .

[0093] Message enhancement data 412 : Enhancement data (eg, filters, stickers, or other annotations or enhancements) representing enhancements to be applied to the message image payload 406 , message video payload 408 , or message audio payload 410 of the message 400 . The enhancement data for a sent or received message 400 may be stored in the enhancement table 310 .

[0094] • Message duration parameter 414: A parameter value indicating the amount of time in seconds that the content of the message (eg, message image payload 406, message video payload 408, message audio payload 410) is to be presented to or made accessible to the user via the message client 104.

[0095] Message geolocation parameters 416: Geolocation data (e.g., latitude and longitude 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 a content item included in the content (e.g., a specific image within a message image payload 406 or a specific video in a message video payload 408).

[0096] Message story identifier 418: An identifier value that identifies one or more content collections (e.g., a "story" identified in story table 312) associated with a particular content item in message image payload 406 of message 400. For example, multiple images within message image payload 406 may each be associated with multiple content collections using an identifier value.

[0097] Message tags 420: Each message 400 may be tagged with a plurality of tags, each of which indicates the subject of the 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 tags 420 indicating the relevant animal. The tag value may be manually generated based on user input, or may be automatically generated using, for example, image recognition.

[0098] • Message sender identifier 422: An identifier (eg, a messaging system identifier, an email address, or a device identifier) ​​that indicates the user of the client device 102 on which the message 400 was generated and from which the message 400 was sent.

[0099] • Message recipient identifier 424: Indicates an identifier (eg, a messaging system identifier, an email address, or a device identifier) ​​of the user of the client device 102 to which the message 400 is addressed.

[0100] The content (e.g., value) of each component of message 400 may be a pointer to a location in a table in which the content data value is stored. For example, the image value in message image payload 406 may be a pointer to a location in image table 316 (or the address of a location in image table 316). Similarly, the value in message video payload 408 may point to data stored in video table 314, the value stored in message enhancement 412 may point to data stored in enhancement table 310, the value stored in message story identifier 418 may point to data stored in story table 312, and the values ​​stored in message sender identifier 422 and message recipient identifier 424 may point to user records stored in entity table 308.

[0101] Figure 5 is an interactive diagram illustrating a process 500 for executing a shortcut representing a combination of separate functions applied in association with capturing an image according to some example embodiments. Figure 1 Message client 104, Figure 2 Process 500 is described with reference to the enhancement system 208, the camera mode system 216, the audio track system 218, and the shortcut system 220 of the embodiment of the present invention. However, one or more blocks (or operations) of process 500 can be performed by one or more other components and / or other suitable devices. Further for the purpose of illustration, the blocks (or operations) of process 500 are described herein as occurring in series or linearly. However, multiple blocks (or operations) of process 500 can occur in parallel or simultaneously. In addition, the blocks (or operations) of process 500 do not need to be performed in the order shown, and / or one or more blocks (or operations) of process 500 do not need to be performed and / or can be replaced by other operations. When the operation of process 500 is completed, process 500 can terminate. In addition, process 500 can correspond to a method, a program, an algorithm, etc.

[0102] The message client 104 may be associated with a corresponding user of the message server system 108, and the user may be associated with a user account of the message server system 108. As described above, a user may be identified by the message server system 108 based on a unique identifier (e.g., a message system identifier, an email address, and / or a device identifier) ​​associated with the user account of the user. In addition, the message server system 108 may implement and / or work in conjunction with a social network server 124 that is configured to identify other users (e.g., friends) with whom a particular user has relationships.

[0103] As described herein, the messaging client 104 (e.g., in conjunction with the messaging server system 108) provides one or more user interfaces for applying shortcuts to image data. As described above, shortcuts correspond to combinations of separate functions. Through a single gesture (e.g., a tap or a press), a user can select a particular shortcut from a list of available shortcuts. In response, the messaging client 104 applies the selected shortcut corresponding to the combination of separate functions to the image captured by the device camera.

[0104] exist Figure 5 In the example of , the operations of boxes 502 to 504 can correspond to the first stage, and the operations of boxes 508 to 528 can correspond to the second stage. The first stage involves the generation of shortcuts and the storage of shortcuts within a database (e.g., shortcut table 318). In addition, the second stage involves presenting available shortcuts for image data captured by the device camera and applying the selected shortcut. It will be appreciated that the second stage can occur shortly after the first stage, or after an extended period of time after the first stage. Therefore, for illustrative purposes, Figure 6 Includes a dashed line separating the first and second stages.

[0105] At block 502, the shortcut system 220 generates shortcuts (e.g., where each shortcut corresponds to a combination of separate functions) for execution with respect to an image captured by a device camera. The image may correspond to a live video feed captured by a camera (e.g., a rear camera or a front camera) of the client device 102. Alternatively or additionally, the image may correspond to an image (e.g., a photo) stored in association with a user of the client device 102 (e.g., in a photo library).

[0106] The shortcut system 220 may correspond to a subsystem of the messaging system 100 and may be supported on the client side by the messaging client 104 and / or on the server side by the application server 114. Thus, the generation of shortcuts may be implemented on the client side, on the server side, and / or in a combination of the client side and the server side.

[0107] Shortcuts may be generated manually (e.g., by a system administrator) in conjunction with an appropriate interface provided by the shortcut system 220. Alternatively, the shortcut system 220 may cause shortcuts to be automatically generated based on a combination of individual functions associated with previous media content items stored by the system (e.g., popular media content items in a content feed as discussed below).

[0108] exist Figure 5In the example of , the shortcut is depicted as applying a combination of all three of an augmented reality content item (e.g., per augmentation system 208), a camera mode (e.g., per camera mode system 216), and an audio track (e.g., per audio track system 218) to a captured image. However, as described above, a shortcut may apply a combination of any two of an augmented reality content item, a camera mode, an audio track, or other individual functions.

[0109] In addition, a single shortcut can have multiple augmented reality content items, camera modes, and / or audio tracks associated with it. For example, where a timeline mode is included, each clip (or segment) in a series of video clips can be associated with a corresponding augmented reality content item and / or audio track. A default augmented reality content item and / or audio track can be predefined for a shortcut to apply the default augmented reality content item and / or audio track when the shortcut is activated. When the shortcut is applied, the remaining augmented reality content items and / or audio tracks can be presented as selectable options.

[0110] The shortcut system 220 stores the shortcuts (block 504). For example, the shortcut system 220 is configured to store the shortcuts in a shortcut table 318. As described above, for each shortcut, the shortcut table 318 stores a combination of the shortcut name, the function of the shortcut, a corresponding indication of an available preview of the shortcut, and / or object properties associated with the shortcut. In the case where the shortcut includes multiple augmented reality content items, the shortcut table 318 may also store an indication of the above-mentioned default augmented reality content item.

[0111] The messaging client 104 receives user input to display an interface associated with one or more of the stored shortcuts (block 506). As described herein, the messaging client 104 provides different user interface elements with user-selectable elements for application-specific shortcuts.

[0112] For example, the available shortcuts may be presented as a list of selectable elements (eg, icons) within the camera center interface, as shown below with respect to FIG. 7A to FIG. 7B Further discussed. When an image is captured via the device camera, the camera center interface can be displayed in response to a user selection of a corresponding icon (e.g., a camera interface button). In one or more embodiments, the camera center interface includes a first portion for selecting to activate different modes such as the timeline mode, timer mode, and slow motion mode mentioned above. In addition, the camera center interface includes a second portion for displaying a list of available shortcuts, such as corresponding to all available shortcuts stored in the shortcut table 318.

[0113] In another example, available shortcuts may be represented as selectable elements (eg, icons) associated with the display of a media content item, as described below with respect to Fig. 9 Further discussed. For example, media content items can be displayed as part of a content feed provided by the messaging system 100. For example, the messaging system 100 can provide different types of content feeds that can be selected by the user for viewing. As described above, the messaging system 100 allows end users to broadcast media content (e.g., media content items, stories) to other users of the messaging system 100. In a first example of a content feed, the messaging system 100 can select a group of media content items for viewing based on the overall user popularity of the submitted media content (e.g., based on the number of system-wide views, user-submitted comments, user-submitted recognitions, etc.). In another example of a content feed, the messaging system 100 provides a collection of content associated with a user's friends (e.g., stories). In another example of a content feed, the messaging system 100 provides a collection of content associated with a system publisher (e.g., a merchant, a social media influencer, an enterprise, an advertiser, etc.). In some cases, a specific media content item in a content feed can have a corresponding shortcut associated with it (e.g., a combination of an augmented reality content item, a camera mode, and / or an audio track). In this case, the messaging client 104 may display selectable elements (eg, icons) associated with the display of the media content item.

[0114] In yet another example, one or more shortcuts may be represented as corresponding selectable elements (eg, icons) within the scan result interface, as described below with respect to FIG. 10A to FIG. 10C Further discussion. Figure 6 As discussed, a user may initiate a scan operation to detect an object within a captured image. In response, the messaging client 104 provides a scan result interface that may indicate one or more shortcuts associated with the detected object. In addition, the scan result interface may include additional portions that indicate the identified object and / or present available augmented reality content items associated with the object for application to the captured image.

[0115] Therefore, at box 506, the message client 104 receives user input (e.g., a user selection of a camera-centric interface icon, a user selection of a content feed, a user selection to perform a scan operation) to display a corresponding interface related to the shortcut. In response to receiving the user input, the message client 104 sends a request for the shortcut to the shortcut system 220 (operation 508). The shortcut system 220, in response to the request, sends information for the shortcut to the message client 104 (operation 510). In addition, the message client 104 displays the corresponding interface (e.g., camera-centric interface, media content item, scan result interface) together with the shortcut related to the interface (box 512).

[0116] At block 514, the messaging client 104 receives a user selection to apply a shortcut to the captured image. In the case of displaying a camera-centric interface, the user can select one of the selectable elements (e.g., icons) from a list of selectable elements corresponding to available shortcuts. In the case of displaying media content items, the user can select a selectable element (e.g., icon) associated with the display of the media content items. In the case of displaying a scan results interface, the user can select one of the selectable elements (e.g., icons) from a list of selectable elements corresponding to shortcuts related to objects detected in the captured image.

[0117] Figure 5 The example corresponds to a shortcut that applies a combination of all three of an audio track, a camera mode, and an augmented reality content item to captured image data. Therefore, the message client 104 performs the following operations: sends a request for an audio track corresponding to the selected shortcut to the audio track system 218 (operation 516); sends a request for a camera mode corresponding to the selected shortcut to the camera mode system 216 (operation 518); sends a request for an augmented reality content item corresponding to the selected shortcut to the augmentation system 208 (operation 520). As described above, each of the augmentation system 208, the camera mode system 216, and the audio track system 218 can correspond to a subsystem of the message system 100 and can be supported by the message client 104 on the client side and / or supported by the application server 114 on the server side.

[0118] The audio track system 218, the camera mode system 216, and the augmentation system 208 provide corresponding audio tracks (operation 522), camera modes (operation 524), and augmented reality content items (operation 526) for capturing image data. The message client 104 presents the camera based on the combination of the audio track, the camera mode, and the augmented reality content item (block 528). In other words, the image data captured by the camera is presented and modified in real time based on the audio track, the camera mode, and the augmented reality content item.

[0119] In one or more embodiments, associated with the application, the message client 104 displays a banner indicating the combination of individual functions corresponding to the shortcut. In addition, the banner indicates the name of the shortcut and a second user-selectable element (e.g., icon) for stopping the combination of individual functions from being applied to the captured image data.

[0120] In one or more embodiments, a user may select an interface element (e.g., a button) for generating a media content item based on captured image data. For example, a user selection of a button causes generation of a media content item including an image (e.g., in response to a press / tap gesture of the button) and / or a video (e.g., in response to a press and hold gesture of the button). The media content item may be sent as a message to a friend, included in a story, etc.

[0121] By generating, maintaining and storing shortcuts for combining separate functions, the amount of user input typically required to perform separate functions can be reduced. As described above, shortcuts can be applied via a single user gesture (e.g., tap, press) that selects a shortcut. Without providing shortcuts, an end user may need to perform several gestures in order to perform a combination of separate functions. Therefore, the messaging system 100 saves time for the user and reduces the computing resources / processing power associated with having to apply separate functions separately. In addition, a user interface that displays available shortcuts can be more attractive to users of the messaging system 100.

[0122] Figure 6 is an interactive diagram illustrating a process 600 for presenting available shortcuts based on objects detected in a captured image according to some example embodiments. Figure 1 The message client 104 and Figure 2The object detection system 210 and shortcut system 220 of process 600 are used to describe process 600. However, one or more frames (or operations) of process 500 can be performed by one or more other components and / or other suitable devices. Further for the purpose of illustration, the frames (or operations) of process 600 are described as occurring in series or linearly in this article. However, multiple frames (or operations) of process 600 can occur in parallel or simultaneously. In addition, the frames (or operations) of process 600 do not need to be performed in the order shown, and / or one or more frames (or operations) of process 600 do not need to be performed and / or can be replaced by other operations. When the operation of process 600 is completed, process 600 can terminate. In addition, process 600 can correspond to method, program, algorithm, etc.

[0123] As described above, the messaging client 104 provides different interfaces for presenting available shortcuts. One such interface is a scan result interface that is displayed in response to a user input to perform a scan operation. Figure 6 Corresponding to displaying shortcuts based on objects detected according to the scanning operation. In this regard, Figure 6 The process 600 generally corresponds to Figure 5 Operations 506 to 512.

[0124] At box 602, the message client 104 receives user input to identify an object depicted in a captured image. In one or more embodiments, the message client 104 activates a camera of the client device 102 (e.g., when the message client 104 is started). The message client 104 allows the user to request a scan of one or more items in a camera feed captured by the camera. In one or more embodiments, the message client 104 detects physical contact between a finger of the user's hand and an area of ​​the touch screen for a threshold period of time. For example, the message client 104 determines that the user touches and holds his finger on the screen for a threshold time (e.g., two seconds).

[0125] Alternatively or additionally, the messaging client 104 receives a user selection of a dedicated scanning option (e.g., a button) presented with the camera feed. In response, the messaging client 104 captures the image being displayed on the screen in conjunction with the object detection system 210 and processes the image to identify a plurality of objects based on the image. In an alternative embodiment, the captured image may correspond to an image / video stored in association with the user of the client device 102, for example, in a photo library (e.g., associated with the operating system of the client device 102 and / or associated with a user profile on the messaging system 100).

[0126] Messaging client 104 sends a request to object detection system 210 to identify an object in the captured image (operation 604). The request may include the image data itself (e.g., if captured in real time and / or stored locally on client device 102). Alternatively, the request may reference a remote image (e.g., if stored in association with a user profile on messaging system 100).

[0127] The object detection system 210 determines properties of the object in the captured image (block 606). As described above, the object detection system 210 may correspond to a subsystem of the messaging system 100 and may be supported on the client side by the messaging client 104 and / or on the server side by the application server 114. In one or more implementations, the detection of objects within the captured image may be implemented on the client side, the server side, and / or in a combination of the client side and the server side.

[0128] As further described above, the object detection system 210 is configured to implement or otherwise access an object recognition algorithm (e.g., including a machine learning algorithm) that is configured to scan a captured image and detect / track the movement of an object within the image. For example, the types of objects that can be detected by the object detection system 210 include, but are not limited to: human faces, parts of the human body, animals and parts thereof, landscapes, natural objects, inanimate objects (e.g., chairs, books, cars, buildings, other structures), illustrations of objects (e.g., on posters and / or flyers), text-based objects, equation-based objects, etc. In addition, the object detection system 210 is configured to determine or otherwise access attributes of the object, such as name, type, genre, color, size, shape, texture, geographic location, and / or other supplemental information (e.g., song name / artist of an object corresponding to media).

[0129] The object detection system 210 is also configured to determine or otherwise access attributes of the identified objects. For example, with respect to an object corresponding to clothing, the object detection system 210 can determine attributes such as the type of object (e.g., dog, chair), the name of the object (e.g., the name / model of a particular chair), color, size, and / or shape. As described above, the object detection system 210 can also determine attributes corresponding to keywords that have been sponsored by a third party. In response to determining that a given attribute corresponds to a sponsored keyword, the object detection system 210 can rank the attribute higher relative to other attributes.

[0130] The object detection system 210 sends the attributes of the object to the message client 104 (operation 608). In doing so, the object detection system 210 may also provide ranking information for the attributes.

[0131] The messaging client 104 sends a request for a shortcut to the shortcut system 220 based on the attributes received from the object detection system 210 (operation 610). For example, if a single object (e.g., a dog) is depicted in the captured image, the request may include attributes related to the single object (e.g., dog, dog breed, color, etc.). In another example, if multiple objects (e.g., multiple animals, people and animals, animals and landscapes) are depicted in the captured image, the request may include corresponding attributes of the multiple objects.

[0132] The shortcut system 220 searches for and selects one or more candidate shortcuts associated with the attributes received from the message client 104 (block 612). As described above, the shortcut system 220 may correspond to a subsystem of the message system 100 and may be supported on the client side by the message client 104 and / or on the server side by the application server 114. In one or more implementations, the selection of shortcuts via the shortcut system 220 may be implemented on the client side, on the server side, and / or in a combination of the client side and the server side.

[0133] The shortcut system 220 is configured to search for one or more shortcuts corresponding to the attributes received from the message client 104 in the shortcut table 318. As described above, the shortcut table 318 stores attributes (e.g., as metadata) in association with the shortcut. In addition, a specific shortcut may have one or more augmented reality content items associated with it. Each of the one or more augmented reality content items may have attributes (e.g., metadata) associated with it. In one or more embodiments, the attributes stored in association with a specific shortcut may correspond to the union of the attributes associated with one or more augmented reality content items of the shortcut. The shortcut system 220 may perform a search by comparing the attributes (e.g., object type, name, color, size, and / or shape) received at operation 610 with the corresponding attributes associated with the shortcut stored in the shortcut table 318.

[0134] In one or more embodiments, the shortcut system 220 may prioritize higher ranked attributes over lower ranked attributes. In the case where the received attributes correspond to multiple objects, the shortcut system 220 may select a corresponding set of shortcuts based on the attributes. In the case where the attributes correspond to a single object, the shortcut system 220 may select a single shortcut corresponding to the attribute.

[0135] The shortcut system 220 can calculate the corresponding relevance score of the shortcut based on the number or frequency of confirmed matches between the matching attributes, for example. The relevance score can be used to limit the number of selected shortcuts (e.g., a predefined number, such as three shortcuts) and / or to display the shortcuts in a ranked order.

[0136] Thus, at block 612, the shortcut system 220 determines candidate shortcuts for sending to the messaging client 104. Each shortcut corresponds to a combination of separate functions to be applied to the captured image (e.g., at least two of an augmented reality content item, a camera mode, an audio track, or other functions). Upon completion of selecting the candidate shortcuts, the shortcut system 220 sends an indication of the selected shortcut to the messaging client 104 along with a relevance score (if applicable) (operation 614).

[0137] The message client 104 displays the selected shortcut in the scan result interface (block 616). Figure 5 The scan result interface indicates one or more shortcuts related to the detected object. In addition, the scan result interface includes additional portions that indicate the identified object and / or present available augmented reality content items related to the object for application to the captured image. The scan result interface may include additional portions that indicate the identified object and / or present available augmented reality content items related to the object for application to the captured image.

[0138] The shortcuts are displayed within the scan results interface as user-selectable entries for applying the corresponding shortcuts to the captured image data (e.g., live video feed). Figure 6 Can correspond to Figure 5 Operations 506 to 512. Therefore, after completing Figure 6 After block 616 in FIG. 1 , the messaging system 100 may then cause a user selection of a shortcut to be received and the user to select the shortcut to be received. Figure 5 Operations 514 to 528 apply the selected shortcut.

[0139] FIG. 7A to FIG. 7B An example user interface 702 is shown for presenting a list of available shortcuts according to some example embodiments. The user interface 702 includes a capture image 704 and a camera centric interface 706. The camera centric interface 706 includes a timeline mode button 708, a timer mode button 710, a slow motion mode button 712, and a list 714 of shortcuts. Fig. 7A The top portion of the camera center interface 706 (which is scrollable) is depicted, and Figure 7B The bottom portion of the camera center interface 706 is depicted after scrolling down.

[0140] As mentioned above about Figure 5 As described, when an image (e.g., captured image 704) is captured via a device camera, the messaging client 104 may present a user interface 702 in response to a user selection of a corresponding icon (e.g., a camera interface button not shown). The first portion of the camera center interface 706 provides user selectable elements 708 to 712 for activating a timeline mode, a timer mode, and a slow motion mode, respectively.

[0141] The camera center interface 706 includes a second portion for displaying a list 714 of shortcuts. FIG. 7A to FIG. 7B , the list of shortcuts 714 presents individual entries of available shortcuts (e.g., stored in the shortcut table 318). Each entry within the list of shortcuts 714 includes the name of the shortcut, a preview button (e.g., depicted as a thumbnail) for previewing the shortcut, a set of icons that respectively depict or otherwise represent individual functions combined in association with the shortcut, and a user-selectable element (a "+" icon) for applying the shortcut to the captured image 704.

[0142] As described above, some shortcuts may have multiple augmented reality content items, camera modes, and / or audio tracks associated with them. Figure 7B In the example of , the first shortcut “Help your pet go viral” is depicted as having a corresponding set of icons corresponding to multiple augmented reality content items (in a stacked manner), an enabled timeline mode, and an audio track.

[0143] FIG. 8A to FIG. 8B An example user interface for applying a shortcut to a captured image and for presenting a preview of the shortcut is shown according to some example embodiments. Fig. 8A Depicted is a user interface 802 for applying a shortcut to a capture image 806. The user interface 802 includes the capture image 806, a banner 808, a timeline mode button 810, an audio track button 812, a carousel interface 814, a selected AR icon 816, and an audio track title 818.

[0144] The carousel interface 814 allows the user to cycle through and / or select different augmented reality content items to apply / display for the captured image 806. Each of the available augmented reality content items is represented by an icon that the user can select to switch to the corresponding augmented reality content item. In one or more embodiments, the icon corresponding to the active augmented reality content item (e.g., the selected AR icon 816) is displayed in a different manner (e.g., larger than the remaining icons) relative to the remaining icons. User selection of the selected AR icon 816 causes the generation of a media content item to be sent to a friend, included in a story, etc., wherein the media content item includes an image of the screen content (e.g., in response to a press / tap gesture to the selected AR icon 816) and / or a video (e.g., in response to a press and hold gesture to the selected AR icon 816).

[0145] In one or more embodiments, the user interface 802 is presented by the messaging client 104 in response to the user selecting to apply the selected shortcut to the captured image data. Figure 5 As described, shortcuts can be selected via different user interfaces, including a camera center interface, a scan result interface, and a display of media content items. In addition, the selected shortcut corresponds to a combination of application individual functions.

[0146] exist Fig. 8A In the example of , the combination of separate functions includes an augmented reality content item, a timeline mode, and an audio track. In one or more embodiments, the augmented reality content item is indicated by an enabled (e.g., highlighted) display of the timeline mode button 810 and a selected AR icon 816, which indicates an active augmented reality content item. Fig. 8A In the example of , the augmented reality content item superimposes virtual sunglasses on the dog depicted in the captured image 806 (e.g., corresponding to the real-time video). In the carousel interface 814, the additional augmented reality content items of the shortcut can be presented as priority (e.g., higher ranked) augmented reality content items. The audio track is indicated by the activation (e.g., highlighting) of the audio track button 812 and by the audio track title 818 (e.g., which can also include the artist name in some embodiments).

[0147] In addition, banner 808 is configured to display information related to the selected shortcut. Banner 808 indicates the name of the shortcut (e.g., "Help your pet go viral"). In addition, banner 808 includes a user-selectable element (e.g., an "enable" icon) for stopping the application of the shortcut to the captured image data.

[0148] In another example, Figure 8BA user interface 804 is depicted for presenting a preview 820 of a shortcut. The user interface 804 includes the preview 820 and a shortcut button 822. In one or more embodiments, the message client 104 responds to selecting a shortcut in a list of shortcuts (e.g., in accordance with FIG. 7A to FIG. 7B ) and presents user interface 804 in response to a user selection of a preview button (depicted as a thumbnail).

[0149] The preview 820 corresponds to a previous media content item (e.g., stored in the shortcut table 318) that applied a shortcut to another user. The shortcut includes applying an augmented reality content item (e.g., a sunglasses overlay) as well as an audio track and a timeline mode. The user interface 804 also includes a shortcut button 822, and a user selection of the shortcut button 822 is executed for a live capture image (e.g., similar to Fig. 8A ) shortcut to the app preview.

[0150] Fig. 9 An example user interface 902 is shown presenting a media content item 904 along with a shortcut icon 906 for executing a shortcut associated with the media content item according to some example embodiments. Figure 5 As shown, media content item 904 may be displayed in association with a content feed provided by messaging system 100. Media content item 904 may have been broadcast by another user, such as a friend of the end user or a publisher associated with messaging system 100.

[0151] exist Fig. 9 In the example of , the shortcut applies an augmented reality content item (e.g., a sunglasses overlay) as well as an audio track and a timeline mode. In addition, user selection of shortcut icon 906 causes the messaging client 104 to capture an image (e.g., similar to a video) of the live scene. Fig. 8A ) to apply the corresponding shortcut.

[0152] FIG. 10A to FIG. 10B An example user interface 1002 is shown for presenting available shortcuts based on objects detected via a scanning operation according to some example embodiments. Fig. 10A The user interface 1002 includes a capture image 1004 , a shutter button 1006 , and a scan button 1008 .

[0153] exist Fig. 10A In the example of , the client device 102 captures an image (e.g., a live video feed) from a rear camera of the client device 102. In this example, the captured image 1004 depicts a dog. Fig. 10AThe example of shows a captured image 1004 captured by a rear camera of the client device 102, but the messaging client 104 may instead capture an image (eg, a live video feed) from a front camera.

[0154] The user interface 1002 includes a shutter button 1006 for generating a media content item to, for example, send to a friend, include in a story, etc., the media content item including an image of the screen content (e.g., in response to a press / tap gesture on the shutter button 1006) and / or a video (e.g., in response to a press-and-hold gesture on the shutter button 1006).

[0155] In one or more embodiments, a user of the client device 102 can provide a touch input to the messaging client 104 to perform a scanning operation to identify an object in the captured image 1004. For example, the touch input corresponds to a press and hold gesture (e.g., for at least one second) at a predefined portion of the user interface 1002 (e.g., a portion of the device screen that is displaying the captured image 1004). Alternatively or additionally, the user interface 1002 includes a scan button 1008. For example, the scan button 1008 corresponds to a dedicated button for the user to perform a scanning operation.

[0156] like Fig. 10B As shown, the message client 104 is configured to display a scan indicator 1010 to indicate that the message client 104 is performing a scan operation. In one or more embodiments, the scan indicator 1010 is displayed for a duration of the scan (e.g., a predetermined duration of 2 seconds). The scan indicator 1010 may include an interface element (e.g., an "x" icon) for terminating the scan.

[0157] During the scanning operation, the messaging client 104 (e.g., in conjunction with the object detection system 212) detects objects in the captured image 1004 and attributes of the detected objects. For example, the object detection system 210 detects FIG. 10A to FIG. 10C In response to determining that the attribute is related to an animal (e.g., a dog), the message client 104 (in conjunction with the shortcut system 220) is configured to select a shortcut associated with the detected attribute of the animal. Fig. 10C As shown, the messaging client 104 is configured to display a representation of the selected shortcut.

[0158] Fig. 10C The user interface 1002 is shown updated to include a scan result interface 1012 for displaying various scan results while continuing to display the captured image 1004. The scan result interface 1012 indicates shortcuts for selections related to properties of the detected object. Fig. 10CIn the example of , scan result interface 1012 indicates one selected shortcut (although multiple shortcuts may have been selected and displayed within scan result interface 1012). The selected shortcut is indicated by displaying the name of the shortcut, a preview button (e.g., depicted as a thumbnail) for previewing the shortcut, a set of icons that each depict or otherwise represent separate functions combined in association with the shortcut, and an interface element 1016 (an "Open Shortcut in Camera" button) that is selectable to apply the shortcut to capture image 1004.

[0159] In addition, the scan results interface may include additional portions that indicate the recognized object (e.g., interface element 1014) and / or present available augmented reality content items related to the object for application to the captured image (e.g., interface element 1018).

[0160] Fig.11 is a flowchart illustrating a process for presenting shortcuts based on objects detected via a scanning operation according to some example embodiments. Figure 1 104 to describe process 1100. However, one or more frames (or operations) of process 1100 can be performed by one or more other components and / or other suitable devices. Further for the purpose of illustration, the frames (or operations) of process 1100 are described in this article as occurring serially or linearly. However, multiple frames (or operations) of process 1100 can occur in parallel or simultaneously. In addition, the frames (or operations) of process 1100 do not need to be performed in the order shown, and / or one or more frames (or operations) of process 1100 do not need to be performed and / or can be replaced by other operations. When the operation of process 1100 is completed, process 1100 can terminate. In addition, process 1100 can correspond to methods, programs, algorithms, etc.

[0161] The message client 104 receives a user request to identify at least one object depicted in an image captured by a device camera (block 1102). The message client 104 determines properties of the object depicted in the image in response to receiving the user request (block 1104).

[0162] The message client 104 selects a shortcut associated with the properties of the object from a plurality of shortcuts for execution on the image, each shortcut in the plurality of shortcuts corresponding to a combination of separate functions to be applied to the image (block 1106). The plurality of shortcuts can be accessed via a database configured to store the plurality of shortcuts.

[0163] The combination of separate functions may include at least two of the following: an augmented reality content item to be applied to an image, a camera mode, or an audio track. The camera mode may correspond to at least one of the following: a timeline mode for capturing a series of video clips, a timer mode for setting when to start video capture, and a slow motion mode for recording video in slow motion.

[0164] The message client 104 causes an interface with a user-selectable element to be displayed for performing a selected shortcut for the image (block 1108). The message client 104 may receive a user selection of the user-selectable element via the interface and, in response to receiving, apply the combination of separate functions to the image. The message client 104 may generate a media content item based on applying the combination of separate functions to the image.

[0165] The messaging client 104 may display a banner in association with the application indicating the combination of individual functions corresponding to the shortcut and the name of the shortcut. The banner may include a second user selectable element for stopping applying the combination of individual functions to the image.

[0166] The interface may also include a first interface element and a second interface element separate from the user-selectable element. The first interface element may identify the object, and the second interface element may present available augmented reality content items related to the object for application to the image.

[0167] Fig.12 is a schematic diagram illustrating an access restriction process 1000, according to which access to content (e.g., a multimedia payload of an ephemeral message 1202 and associated data) or a collection of content (e.g., an ephemeral message group 1204) can be time-restricted (e.g., made ephemeral).

[0168] The ephemeral message 1202 is shown to be associated with a message duration parameter 1206, the value of which determines the amount of time that the message client 104 will display the ephemeral message 1202 to the receiving user of the ephemeral message 1202. In one example, depending on the amount of time specified by the sending user using the message duration parameter 1206, the receiving user may view the ephemeral message 1202 for up to 10 seconds.

[0169] The message duration parameter 1206 and the message recipient identifier 424 are shown as inputs to a message timer 1210, which is responsible for determining the amount of time that the transient message 1202 is shown to a particular receiving user identified by the message recipient identifier 424. In particular, the transient message 1202 is shown to the associated receiving user only for the period of time determined by the value of the message duration parameter 1206. The message timer 1210 is shown as providing an output to a more general transient timer system 202, which is responsible for the overall timing of displaying content (e.g., the transient message 1202) to the receiving user.

[0170] Short message 1202 Fig.12 1204 (e.g., a collection of messages in a personal story or an event story). The ephemeral message group 1204 has an associated group duration parameter 1208, the value of which determines the duration for which the ephemeral message group 1204 is presented and accessible to users of the messaging system 100. For example, the group duration parameter 1208 may be the duration of a concert, where the ephemeral message group 1204 is a collection of content about the concert. Alternatively, a user (an owning user or a curator user) may specify a value for the group duration parameter 1208 when performing setup and creation of the ephemeral message group 1204.

[0171] In addition, each ephemeral message 1202 within the ephemeral message group 1204 has an associated group participation parameter 1212, the value of which determines the duration for which the ephemeral message 1202 is accessible within the context of the ephemeral message group 1204. Thus, a particular ephemeral message group 1204 may "expire" and become inaccessible within the context of the ephemeral message group 1204 before the ephemeral message group 1204 itself expires according to the group duration parameter 1208. The group duration parameter 1208, the group participation parameter 1212, and the message recipient identifier 424 each provide inputs to a group timer 1214, which is operable to first determine whether a particular ephemeral message 1202 of the ephemeral message group 1204 is to be displayed to a particular receiving user, and if so, how long to display it. Note that the identity of the particular receiving user is also known to the ephemeral message group 1204 due to the message recipient identifier 424.

[0172] Thus, the group timer 1214 is operable to control the total lifespan of the associated ephemeral message group 1204 and the individual ephemeral messages 1202 included in the ephemeral message group 1204. In one example, each ephemeral message 1202 within the ephemeral message group 1204 remains viewable and accessible for a period of time specified by the group duration parameter 1208. In another example, within the context of the ephemeral message group 1204, a particular ephemeral message 1202 may expire based on the group participation parameter 1212. Note that even within the context of the ephemeral message group 1204, the message duration parameter 1206 may still determine the duration for which a particular ephemeral message 1202 is displayed to a receiving user. Thus, the message duration parameter 1206 determines the duration for which a particular ephemeral message 1202 is displayed to a receiving user, regardless of whether the receiving user is viewing the ephemeral message 1202 within or outside the context of the ephemeral message group 1204.

[0173] The transient timer system 202 may also be operable to remove a particular transient message 1202 from a transient message group 1204 based on a determination that an associated group participation parameter 1212 has been exceeded. For example, where a sending user has established a group participation parameter 1212 of 24 hours from posting, the transient timer system 202 will remove the associated transient message 1202 from the transient message group 1204 after the designated 24 hours. The transient timer system 202 is also operable to remove a transient message group 1204 when the group participation parameter 1212 for each transient message 1202 within the transient message group 1204 has expired, or when the transient message group 1204 itself has expired according to the group duration parameter 1208.

[0174] In some use cases, the creator of a particular ephemeral message group 1204 may specify an indefinite group duration parameter 1208. In this case, the expiration of the group participation parameter 1212 for the last remaining ephemeral message 1202 within the ephemeral message group 1204 will determine when the ephemeral message group 1204 itself expires. In this case, a new ephemeral message 1202 with a new group participation parameter 1212 added to the ephemeral message group 1204 effectively extends the life of the ephemeral message group 1204 to a value equal to the group participation parameter 1212.

[0175] In response to the transient timer system 202 determining that the transient message group 1204 has expired (e.g., is no longer accessible), the transient timer system 202 communicates with the messaging system 100 (and, for example, in particular, the messaging client 104) to cause the indicia (e.g., icon) associated with the relevant transient message group 1204 to no longer be displayed within the user interface of the messaging client 104. Similarly, when the transient timer system 202 determines that the message duration parameter 1206 for a particular transient message 1202 has expired, the transient timer system 202 causes the messaging client 104 to no longer display the indicia (e.g., icon or text identification) associated with the transient message 1202.

The term "processor" is intended to include multi-core processors, which may include two or more independent processors (sometimes referred to as "cores") that can execute instructions simultaneously. Although Fig.13 Multiple processors 1304 are shown, but the machine 1300 may include a single processor with a single core, a single processor with multiple cores (e.g., a multi-core processor), multiple processors with a single core, multiple processors with multiple cores, or any combination thereof.

[0179] I / O components 1302 may include various components for receiving input, providing output, generating output, transmitting information, exchanging information, capturing measurements, etc. The specific I / O components 1302 included in a particular machine will depend on the type of machine.

[0181] Environmental components 1334 include, for example, one or more cameras (with still image / photo and video capabilities), lighting sensor components (e.g., photometers), temperature sensor components (e.g., one or more thermometers that detect ambient temperature), humidity sensor components, pressure sensor components (e.g., barometers), acoustic sensor components (e.g., one or more microphones that detect background noise), proximity sensor components (e.g., infrared sensors that detect nearby objects), gas sensors (e.g., gas detection sensors for detecting concentrations of hazardous gases for safety purposes or for measuring pollutants in the atmosphere), or other components that can provide indications, measurements, or signals corresponding to the surrounding physical environment.

[0182] With respect to cameras, client device 102 can have a camera system including, for example, a front-facing camera on a front surface of client device 102 and a rear-facing camera on a rear surface of client device 102. The front-facing camera can, for example, be used to capture still images and videos of a user of client device 102 (e.g., a "selfie"), which can then be enhanced with the enhancement data (e.g., filters) described above. For example, the rear-facing camera can be used to capture still images and videos in a more traditional camera mode, which are similarly enhanced with the enhancement data. In addition to the front-facing camera and the rear-facing camera, client device 102 can also include a 360° camera for capturing 360° photos and videos.

[0183] Additionally, the camera system of the client device 102 may include dual rear cameras (e.g., a main camera and a depth sensing camera), or even triple, quad, or quintuple rear camera configurations on the front and back sides of the client device 102. For example, these multi-camera systems may include a wide-angle camera, an ultra-wide-angle camera, a telephoto camera, a macro camera, and a depth sensor.

[0184] The location component 1336 includes a positioning sensor component (e.g., a GPS receiver component), an altitude sensor component (e.g., an altimeter or barometer that detects air pressure, from which the altitude can be obtained), an orientation sensor component (e.g., a magnetometer), etc.

[0185] A variety of technologies may be used to achieve communication. I / O components 1302 also include communication components 1338 that are operable to couple machine 1300 to network 1322 or device 1324 via corresponding couplings or connections.

For example, the communication component 1338 can include a radio frequency identification (RFID) tag reader component, an NFC smart tag detection component, an optical reader component (e.g., an optical sensor for detecting one-dimensional bar codes such as universal product codes (UPC) bar codes, multi-dimensional bar codes such as quick response (QR) codes, Aztec codes, data matrix, data symbols (Dataglyph), MaxiCode, PDF417, UltraCode, UCC RSS-2D bar codes, and other optical codes) or an acoustic detection component (e.g., a microphone for identifying an audio signal of a tag). In addition, various information can be obtained via the communication component 1338, such as obtaining positioning via Internet Protocol (IP) geolocation, ... and obtaining positioning via Internet Protocol (IP) geolocation. Positioning is obtained through signal triangulation, positioning is obtained via detection of NFC beacon signals that can indicate a specific position, etc.

[0187] Various memories (e.g., main memory 1314, static memory 1316, and memory of processor 1304) and storage unit 1318 may store one or more sets of instructions and data structures (e.g., software) used by or implementing any one or more of the methods or functions described herein. These instructions (e.g., instructions 1310) when executed by processor 1304 cause various operations to implement the disclosed examples.

[0188] The instructions 1310 may be sent or received via a network interface device (e.g., a network interface component included in the communication component 1338) using a transmission medium and using any of several well-known transmission protocols (e.g., Hypertext Transfer Protocol (HTTP)) over the network 1322. Similarly, the instructions 1310 may be sent or received via a coupling (e.g., a peer-to-peer coupling) to the device 1324 using a transmission medium.

[0189] Fig.14 1400 is a block diagram illustrating a software architecture 1404 that may be installed on any one or more of the devices described herein. The software architecture 1404 is supported by hardware such as a machine 1402 including a processor 1420, a memory 1426, and an I / O component 1438. In this example, the software architecture 1404 may be conceptualized as a stack of layers, where each layer provides specific functionality. The software architecture 1404 includes layers such as an operating system 1412, a library 1410, a framework 1408, and an application 1406. In operation, the application 1406 invokes an API call 1450 through the software stack and receives a message 1452 in response to the API call 1450.

[0190] The operating system 1412 manages hardware resources and provides public services. The operating system 1412 includes, for example, a kernel 1414, services 1416, and drivers 1422. The kernel 1414 serves as an abstraction layer between the hardware and other software layers. For example, the kernel 1414 provides functions such as memory management, processor management (e.g., scheduling), component management, networking, and security settings. Services 1416 can provide other public services to other software layers. Drivers 1422 are responsible for controlling or interfacing with the underlying hardware. For example, drivers 1422 may include display drivers, camera drivers, or Low-power drivers, Flash drivers, Serial communication drivers (e.g., USB drivers), Drivers, audio drivers, power management drivers, etc.

[0191] The libraries 1410 provide a common low-level infrastructure used by the applications 1406. The libraries 1410 may include a system library 1418 (e.g., a C standard library) that provides functions such as memory allocation functions, string manipulation functions, mathematical functions, etc. In addition, the libraries 1410 may include an API library 1424, such as a media library (e.g., a library for supporting the 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)), a graphics library (e.g., an OpenGL framework for presentation in two dimensions (2D) and three dimensions (3D) in graphical content on a display), a database library (e.g., SQLite providing various relational database functions), a web library (e.g., WebKit providing web browsing functions), etc. The library 1410 may also include various other libraries 1428 to provide many other APIs to the application 1406 .

[0192] The framework 1408 provides a common high-level infrastructure used by the applications 1406. For example, the framework 1408 provides various graphical user interface (GUI) functions, advanced resource management, and advanced positioning services. The framework 1408 can provide a wide range of other APIs that can be used by the applications 1406, some of which can be specific to a particular operating system or platform.

[0193] In an example, applications 1406 may include a home application 1436, a contacts application 1430, a browser application 1432, a book reader application 1434, a positioning application 1442, a media application 1444, a messaging application 1446, a game application 1448, and a variety of other applications such as third-party applications 1440. Applications 1406 are programs that perform functions defined in the program. Various programming languages ​​may be used to create one or more of the applications 1406 constructed in various ways, such as an object-oriented programming language (e.g., Objective-C, Java, or C++) or a procedural programming language (e.g., C or assembly language). In a specific example, third-party applications 1440 (e.g., those created by entities other than the vendor of a particular platform using ANDROID TM or IOS TM Software Development Kit (SDK) can be used to develop applications on platforms such as IOS TM ANDROID TM , Mobile software running on the mobile operating system of the phone or other mobile operating system. In this example, the third-party application 1440 can activate the API call 1450 provided by the operating system 1412 to facilitate the functions described in this article.

[0194] "Carrier signal" refers to any intangible medium that can store, encode or carry instructions for execution by a machine and includes digital or analog communications signals or other intangible media that facilitates communication of such instructions. Instructions may be sent or received over a network using a transmission medium via a network interface device.

[0195] "Client Device" refers to any machine that interfaces with 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, a desktop computer, a laptop computer, a portable digital assistant (PDA), a smart phone, a tablet computer, an ultrabook, a netbook, a laptop computer, a multiprocessor system, a microprocessor-based or programmable consumer electronics product, a game console, a set-top box, or any other communications device that a user may use to access a network.

[0196] "Communications network" means one or more parts of a network, which 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 part of the Internet, a part of the public switched telephone network (PSTN), a plain old telephone service (POTS) network, a cellular telephone network, a wireless network, A network, other type of network, or a combination of two or more such networks. For example, the network or a portion of the network may include a wireless network or a cellular network, and the coupling may be a code division multiple access (CDMA) connection, a global system for mobile communications (GSM) connection, or other type of cellular or wireless coupling. In this example, the coupling may implement any of various types of data transmission technologies, such as single carrier radio transmission technology (1xRTT), evolution data optimized (EVDO) technology, general packet radio service (GPRS) technology, enhanced data rates for GSM evolution (EDGE) technology, the third generation partnership project (3GPP) including 3G, fourth generation wireless (4G) networks, universal mobile telecommunications system (UMTS), high speed packet access (HSPA), world wide interoperability for microwave access (WiMAX), long term evolution (LTE) standards, other data transmission technologies defined by various standard setting organizations, other long distance protocols, or other data transmission technologies.

[0197] "Component" refers to a device, a physical entity, or logic with boundaries defined by function or subroutine calls, branch points, APIs, or other techniques that provide partitioning or modularization for specific processing or control functions. Components can be combined with other components via their interfaces to perform machine processing. Components can be packaged functional hardware units designed for use with other components and can be part of a program that generally performs specific functions in related functions. Components can constitute software components (e.g., codes implemented on machine-readable media) or hardware components. "Hardware components" are tangible units that can perform certain operations and can be configured or arranged in a certain physical manner. In various examples, one or more computer systems (e.g., independent computer systems, client computer systems, or server computer systems) or one or more hardware components (e.g., processors or processor groups) of a computer system can be configured by software (e.g., applications or application parts) to perform hardware components that operate to perform certain operations described herein. Hardware components can also be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware component may include a dedicated circuit or logic that is permanently configured to perform certain operations. The hardware component can be a special processor such as a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC). The hardware component can also include a programmable logic or circuit that is temporarily configured to perform certain operations by software. For example, the hardware component can include software executed by a general-purpose processor or other programmable processor. Once configured by such software, the hardware component becomes a specific machine (or a specific component of a machine) that is uniquely customized to perform the configured function, and is no longer a general-purpose processor. It will be recognized that the decision to implement the hardware component mechanically, in a dedicated and permanently configured circuit, or in a temporarily configured circuit (for example, configured by software) can be driven for cost and time considerations. Therefore, the phrase "hardware component" (or "hardware-implemented component") should be understood to include a tangible entity, that is, an entity that is physically constructed, permanently configured (for example, hardwired) or temporarily configured (for example, programmed) to operate in some way or perform certain operations described herein. Considering an example in which a hardware component is temporarily configured (for example, programmed), it is not necessary to configure or instantiate each of the hardware components at any time. For example, where a hardware component includes a general purpose processor that is configured by software to be a special purpose processor, the general purpose processor may be configured as respectively different special purpose processors (e.g., including different hardware components) at different times. Thus, software configures one or more specific processors to, for example, constitute a specific hardware component at one time and to constitute different hardware components at different times. Hardware components may provide information to other hardware components and receive information from other hardware components. Thus, the described hardware components may be considered to be communicatively coupled.In the case of multiple hardware components being present at the same time, communication can be achieved by signal transmission (e.g., by appropriate circuits and buses) between or among two or more hardware components. In examples where multiple hardware components are configured or instantiated at different times, communication between such hardware components can be achieved, for example, by storing information in a memory structure accessible to multiple hardware components and retrieving information in the memory structure. For example, a hardware component can perform an operation, and the output of the operation is stored in a memory device coupled to the communication ground. Then, other hardware components can access the memory device at a subsequent time to retrieve and process the stored output. The hardware component can also initiate communication with an input device or an output device, and can operate on resources (e.g., a collection of information). The various operations of the example methods described herein can be performed at least in part by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform related operations. Whether it is temporarily configured or permanently configured, such a processor can constitute a processor-implemented component that operates to perform one or more operations or functions described herein. As used herein, "processor-implemented components" refer to hardware components implemented using one or more processors. Similarly, the method described herein can be implemented at least in part by a processor, wherein one or more specific processors are examples of hardware. For example, at least some operations in the operation of the method can be performed by one or more processors or the parts implemented by the processor. In addition, one or more processors can also operate to support the execution of related operations in a "cloud computing" environment or as a "software as a service" (SaaS) operation. For example, at least some operations in the operation can be performed by a computer group (as an example of a machine including a processor), wherein these operations can be accessed via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., API). The execution of some operations in the operation can be distributed between processors, not only can reside in a single machine, but also can be deployed across several machines. In some examples, a processor or a part implemented by a processor can be located in a single geographic location (e.g., in a home environment, an office environment, or a server cluster). In other examples, a processor or a part implemented by a processor can be distributed across several geographic locations.

[0198] "Computer-readable storage media" refers to both machine storage media and transmission media. Therefore, these 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.

[0199] "Transient messages" are messages that are accessible for a limited duration. Transient messages can be text, images, videos, etc. The access time for transient messages can be set by the sender of the message. Alternatively, the access time can be a default setting or a setting specified by the recipient. Regardless of the setting technique, the message is transient.

[0200] "Machine storage media" refers to a single or multiple storage devices and media (e.g., centralized or distributed databases, and associated caches and servers) that store executable instructions, routines, and data. Thus, the term should be considered to include, but is not limited to, solid-state memory and optical and magnetic media, including memory internal or external to the processor. Specific examples of machine storage media, computer storage media, and device storage media include: non-volatile memory, including, for example, semiconductor memory devices such as 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 media", "device storage media", and "computer storage media" mean the same thing and may be used interchangeably in this disclosure. The terms "machine storage media", "computer storage media", and "device storage media" explicitly exclude carrier waves, modulated data signals, and other such media (at least some of which are covered by the term "signal media").

[0201] “Non-transitory computer-readable storage medium” refers to tangible media capable of storing, encoding, or carrying instructions to be executed by a machine.

[0202] "Signal media" refers to any intangible medium that is capable of storing, encoding or carrying instructions executed by a machine, and includes digital or analog communication signals or other intangible media that facilitate the communication of software or data. The term "signal medium" should be deemed to include any form of modulated data signals, carrier waves, etc. The term "modulated data signal" means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. The terms "transmission medium" and "signal medium" mean the same thing and are used interchangeably in this disclosure.
