Patent Application
20230176805
The present disclosure relates generally to providing augmented reality experiences using a software application.
Augmented-Reality (AR) is a modification of a virtual environment. For example, in Virtual Reality (VR), a user is completely immersed in a virtual world, whereas in AR, the user is immersed in a world where virtual objects are combined or superimposed on the real world. An AR system aims to generate and present virtual objects that interact realistically with a real-world environment and with each other. Examples of AR applications can include single or multiple player video games, instant messaging systems, and the like.

Some nonlimiting examples are illustrated in the figures of the accompanying drawings in which:
The description that follows includes systems, methods, techniques, instruction sequences, and computing machine program products that embody illustrative examples of the disclosure. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide an understanding of various examples. It will be evident, however, to those skilled in the art, that examples may be practiced without these specific details. In general, well-known instruction instances, protocols, structures, and techniques are not necessarily shown in detail.
Users often enjoy watching videos of other people opening packages and revealing their contents. Usually, these videos are prerecorded and shared over the Internet with a user's social network. The experience of unboxing is very common on social media and is a genre of content where people unbox a product to get a feel for the product. The experience is very exciting since it yields to anticipation users feel for something shiny and new. In many cases, such unboxing experiences can lead to social-shopping opportunities which create a creative way for users to share their favorite items with friends and spread the word about different products. In many cases, users receive packages and forget to record the videos, which results in missed opportunities for generating content that shows a user's reaction to opening a box.
Some systems create online experiences in which mystery boxes are delivered to users. In such systems, the virtual boxes are opened by simply tapping on the virtual boxes or selecting an open box option. Such experiences are not particularly interesting to share. Augmented reality (AR) and virtual reality (VR) systems provide opportunities for creating unique and engaging content which enhances user engagement with the applications.
The disclosed techniques improve the efficiency of using the electronic device by providing an AR or VR application that includes a shared unboxing experience. Particularly, the disclosed techniques provide a shared VR or AR experience that imitates, in some cases, the physical unboxing experience. In order to keep the experiences unique and engaging, different types of triggers are used to open the same or different sets of boxes. For example, two or more users can work together to open a particular box by performing respective sequences of physical and/or virtual actions. This enhances collaboration and provides for more engaging online social experiences.
In an example, the disclosed techniques cause concurrent display of a shared augmented reality experience comprising a shared virtual box that is in a closed state on a plurality of client devices associated with a plurality of users. The disclosed techniques obtain a sequence of triggers associated with the shared virtual box. First and second inputs are received respectively from first and second client devices of the plurality of client devices. The disclosed techniques determine that the first and second inputs correspond to the sequence of triggers associated with the shared virtual box and, in response, modify the shared virtual box from being displayed on the plurality of devices in the closed state to being displayed in the open state.
In some cases, the disclosed techniques automatically begin capturing a video of the users performing a last set of sequences in the sequence of triggers to share with one or more other users. For example, the disclosed techniques determine that a first portion of the sequence of triggers has been performed. In response, the disclosed techniques automatically activate front-facing cameras of each of the plurality of client devices to capture images or videos of the users successfully opening the shared virtual box by performing a second portion of the sequence of triggers. Concurrently with capturing the images or videos, the disclosed techniques change the state of the shared virtual box from the closed state to the open state to reveal the set of content of the virtual box.
This improves the overall experience of the user in using the electronic device. Also, by automating the video recording of users' reactions to opening a shared virtual box, the overall amount of system resources needed to accomplish a task is reduced.
A messaging client 104 is able to communicate and exchange data with other messaging clients 104 and with the messaging server system 108 via the network 112. The data exchanged between messaging clients 104, and between a messaging client 104 and the messaging server system 108, includes functions (e.g., commands to invoke functions) as well as payload data (e.g., text, audio, video or other multimedia data).
The messaging server system 108 provides server-side functionality via the network 112 to a particular messaging client 104. While certain functions of the messaging system 100 are described herein as being performed by either a messaging client 104 or by the messaging server system 108, the location of certain functionality either within the messaging client 104 or the messaging server system 108 may be a design choice. For example, it may be technically preferable to initially deploy certain technology and functionality within the messaging server system 108 but to later migrate this technology and functionality to the messaging client 104 where a client device 102 has sufficient processing capacity.
The messaging server system 108 supports various services and operations that are provided to the messaging client 104. Such operations include transmitting data to, receiving data from, and processing data generated by the messaging client 104. This data may include message content, client device information, geolocation information, media augmentation and overlays, message content persistence conditions, social network information, and live event information, as examples. Data exchanges within the messaging system 100 are invoked and controlled through functions available via user interfaces (UIs) of the messaging client 104.
Turning now specifically to the messaging server system 108, an Application Programming Interface (API) server 116 is coupled to, and provides a programmatic interface to, application servers 114. The application servers 114 are communicatively coupled to a database server 120, which facilitates access to a database 126 that stores data associated with messages processed by the application servers 114. Similarly, a web server 128 is coupled to the application servers 114, and provides web-based interfaces to the application servers 114. To this end, the web server 128 processes incoming network requests over the Hypertext Transfer Protocol (HTTP) and several other related protocols.
The API server 116 receives and transmits message data (e.g., commands and message payloads) between the client device 102 and the application servers 114. Specifically, the API server 116 provides a set of interfaces (e.g., routines and protocols) that can be called or queried by the messaging client 104 in order to invoke functionality of the application servers 114. The API server 116 exposes various functions supported by the application servers 114, including account registration, login functionality, the sending of messages, via the application servers 114, from a particular messaging client 104 to another messaging client 104, the sending of media files (e.g., images or video) from a messaging client 104 to a messaging server 118, and for possible access by another messaging client 104, the settings of a collection of media data (e.g., story), the retrieval of a list of friends of a user of a client device 102, the retrieval of such collections, the retrieval of messages and content, the addition and deletion of entities (e.g., friends) to an entity graph (e.g., a social graph), the location of friends within a social graph, and opening an application event (e.g., relating to the messaging client 104).
The application servers 114 host a number of server applications and subsystems, including for example a messaging server 118, an image processing server 122, and a social network server 124. The messaging server 118 implements a number of message processing technologies and functions, particularly related to the aggregation and other processing of content (e.g., textual and multimedia content) included in messages received from multiple instances of the messaging client 104. As will be described in further detail, the text and media content from multiple sources may be aggregated into collections of content (e.g., called stories or galleries). These collections are then made available to the messaging client 104. Other processor- and memory-intensive processing of data may also be performed server-side by the messaging server 118, in view of the hardware requirements for such processing.
The application servers 114 also include an image processing server 122 that is dedicated to performing various image processing operations, typically with respect to images or video within the payload of a message sent from or received at the messaging server 118.
Image processing server 122 is used to implement scan functionality of the augmentation system 208 (shown in
The social network server 124 supports various social networking functions and services and makes these functions and services available to the messaging server 118. To this end, the social network server 124 maintains and accesses an entity graph 308 (as shown in
Returning to the messaging client 104, features and functions of an external resource (e.g., a third-party application 109 or applet) are made available to a user via an interface of the messaging client 104. The messaging client 104 receives a user selection of an option to launch or access features of an external resource (e.g., a third-party resource), such as external apps 109. The external resource may be a third-party application (external apps 109) installed on the client device 102 (e.g., a “native app”), or a small-scale version of the third-party application (e.g., an “applet”) that is hosted on the client device 102 or remote of the client device 102 (e.g., on third-party servers 110). The small-scale version of the third-party application includes a subset of features and functions of the third-party application (e.g., the full-scale, native version of the third-party standalone application) and is implemented using a markup-language document. In one example, the small-scale version of the third-party application (e.g., an “applet”) is a web-based, markup-language version of the third-party application and is embedded in the messaging client 104. In addition to using markup-language documents (e.g., a .*ml file), an applet may incorporate a scripting language (e.g., a .*js file or a .json file) and a style sheet (e.g., a .*ss file).
In response to receiving a user selection of the option to launch or access features of the external resource (external app 109), the messaging client 104 determines whether the selected external resource is a web-based external resource or a locally-installed external application. In some cases, external applications 109 that are locally installed on the client device 102 can be launched independently of and separately from the messaging client 104, such as by selecting an icon, corresponding to the external application 109, on a home screen of the client device 102. Small-scale versions of such external applications can be launched or accessed via the messaging client 104 and, in some examples, no or limited portions of the small-scale external application can be accessed outside of the messaging client 104. The small-scale external application can be launched by the messaging client 104 receiving, from an external app(s) server 110, a markup-language document associated with the small-scale external application and processing such a document.
In response to determining that the external resource is a locally-installed external application 109, the messaging client 104 instructs the client device 102 to launch the external application 109 by executing locally-stored code corresponding to the external application 109. In response to determining that the external resource is a web-based resource, the messaging client 104 communicates with the external app(s) servers 110 to obtain a markup-language document corresponding to the selected resource. The messaging client 104 then processes the obtained markup-language document to present the web-based external resource within a user interface of the messaging client 104.
The messaging client 104 can notify a user of the client device 102, or other users related to such a user (e.g., “friends”), of activity taking place in one or more external resources. For example, the messaging client 104 can provide participants in a conversation (e.g., a chat session) in the messaging client 104 with notifications relating to the current or recent use of an external resource by one or more members of a group of users. One or more users can be invited to join in an active external resource or to launch a recently-used but currently inactive (in the group of friends) external resource. The external resource can provide participants in a conversation, each using a respective messaging client 104, with the ability to share an item, status, state, or location in an external resource with one or more members of a group of users into a chat session. The shared item may be an interactive chat card with which members of the chat can interact, for example, to launch the corresponding external resource, view specific information within the external resource, or take the member of the chat to a specific location or state within the external resource. Within a given external resource, response messages can be sent to users on the messaging client 104. The external resource can selectively include different media items in the responses, based on a current context of the external resource.
The messaging client 104 can present a list of the available external resources (e.g., third-party or external applications 109 or applets) to a user to launch or access a given external resource. This list can be presented in a context-sensitive menu. For example, the icons representing different ones of the external application 109 (or applets) can vary based on how the menu is launched by the user (e.g., from a conversation interface or from a non-conversation interface).
The messaging client 104 can present concurrently to a plurality of users one or more shared unboxing AR experiences. In an example, the messaging client 104 can present a shared unboxing AR experience in response to receiving input from a set of client devices 102 (associated with a plurality of users) selecting an option to access a mystery box icon. The messaging client 104 presents a shared virtual box as a representation of the selected shared unboxing AR experience. The shared virtual box can be associated with a time limit during which certain sequences of actions by a group or the plurality of users together can be performed in an attempt to open the shared virtual box. Namely, the shared virtual box can be associated with triggers that can only be satisfied when different users interacting with the same shared virtual box perform respective actions. In this way, a single user is unable to open a shared virtual box by themselves. A particular user who desires to open a shared virtual box may communicate with one or more friends to participate in the unboxing AR experience to satisfy the sequence of triggers. This creates a more engaging social user experience and increases the overall appeal and use of the messaging client 104 and the social network server 124.
In some implementations, the shared virtual box can be associated with one or more sequences of triggers that control when the virtual box is opened (e.g., changed from being in a closed state to being in an open state). Once the shared virtual box is changed to being in an open state (e.g., when a sequence of user inputs or actions from the plurality of users (received from the set of client devices 102) correspond to a sequence of triggers associated with the shared virtual box), a set of contents (e.g., one or more objects) of the shared virtual box are enabled for access by the plurality of users. Different sequences of triggers are associated with different complexities or complexity levels or levels of difficulty of user actions. In one implementation, a first portion of the sequence of triggers corresponding to a first user of the plurality of users can be associated with a first level of complexity of user actions including tapping a particular area of the virtual box. A second portion of the sequence of triggers corresponding to a second user of the plurality of users (working together to open the shared virtual box) can be associated with a second level of complexity of user actions (greater or more difficult than the first level of complexity) including shaking the client device 102 of the second user or performing another suitable gesture. A higher level of complexity of user actions can correspond to a greater number or quantity of actions that need to be performed and/or different types of user actions that are more difficult to perform (e.g., tapping is less difficult than shaking) and/or more difficult challenge questions.
The set of contents of the shared virtual box can vary based on a type of the shared virtual box, a time of day, an experience level of the user, an activeness metric of the user, a cost of the virtual box, current weather conditions, location, number of friends, shared preferences of the plurality of users, and so forth. The set of contents can include a set of related physical or virtual items or a set of unrelated physical or virtual items. In one example, the set of contents includes a set of avatar outfits that are enabled for use by the account or profile of the plurality of users. Specifically, after the shared virtual box is opened, the avatar outfits contained in the shared virtual box are added to accounts of the plurality of users. The messaging client 104 then allows the plurality of users to customize a look of the users' avatars using the avatar outfits contained in the shared virtual box.
In another example, the set of contents include a set of virtual outfits that correspond to real-world articles of clothing. After the shared virtual box is opened, the messaging client 104 enables the plurality of users to select any one of the set of virtual outfits to launch a virtual try-on AR experience. In the virtual try-on AR experience, the messaging client 104 activates a front-facing camera and overlays the selected virtual outfit on a depiction of a given one of the plurality of users in a video stream captured by the front-facing camera. Any other user who participated in opening the shared virtual box can receive a real-time video stream of the given user virtually trying on the selected virtual outfit. If the user is satisfied and likes the selected virtual outfit, the messaging client 104 can receive input from the user that selects an option to purchase the real-world article of clothing corresponding to the virtual outfit. The cost to purchase the real-world article of clothing can be at a discount or lower than the cost to purchase the real-world article of clothing from a merchant prior to opening the virtual box. Namely, as a result of the plurality of users working together successfully opening the shared virtual box, the messaging client 104 can reduce the cost to purchase the real-world article of clothing for each of the plurality of users.
In another example, the set of contents includes additional AR experiences or games. In response to opening the shared virtual box, the additional AR experiences or games are unlocked and made available for the plurality of users to consume and access. In another example, after the virtual box is opened, a virtual portal is displayed in AR on top of a video stream (e.g., captured by a rear-facing camera). The messaging client 104 can detect a location of the users and determine that the users are walking through the virtual portal. In response, the messaging client 104 navigates the users to a new dimension or screen or makes available a set of content for the users to consume. In some examples, the set of content includes audio or video media assets or content items. The audio or video media assets or content items are added to accounts of the users to enable the users to consume alone or together or watch the audio or video media assets or content items in response to opening the shared virtual box. In another example, the set of contents includes one or more non-fungible tokens (NFTs) associated with one or more virtual objects.
The ephemeral timer system 202 is responsible for enforcing the temporary or time-limited access to content by the messaging client 104 and the messaging server 118. The ephemeral timer system 202 incorporates a number of timers that, based on duration and display parameters associated with a message, or collection of messages (e.g., a story), selectively enable access (e.g., for presentation and display) to messages and associated content via the messaging client 104. Further details regarding the operation of the ephemeral timer system 202 are provided below.
The collection management system 204 is responsible for managing sets or collections of media (e.g., collections of text, image video, and audio data). A collection of content (e.g., messages, including images, video, text, and audio) may be organized into an “event gallery” or an “event story.” Such a collection may be made available for a specified time period, such as the duration of an event to which the content relates. For example, content relating to a music concert may be made available as a “story” for the duration of that music concert. The collection management system 204 may 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.
The collection management system 204 further 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 relating to a specific event (e.g., delete inappropriate content or redundant messages). Additionally, the collection management system 204 employs machine vision (or image recognition technology) and content rules to automatically curate a content collection. In certain examples, compensation may be paid to a user for the inclusion of user-generated content into a collection. In such cases, the collection management system 204 operates to automatically make payments to such users for the use of their content.
The augmentation system 208 provides various functions that enable a user to augment (e.g., annotate or otherwise modify or edit) media content associated with a message. For example, the augmentation system 208 provides functions related to the generation and publishing of media overlays for messages processed by the messaging system 100. The augmentation system 208 operatively supplies a media overlay or augmentation (e.g., an image filter) to the messaging client 104 based on a geolocation of the client device 102. In another example, the augmentation system 208 operatively supplies a media overlay to the messaging client 104 based on other information, such as social network information of the user of the client device 102. A media overlay may include audio and visual content and visual effects. Examples of audio and visual content include pictures, texts, logos, animations, and sound effects. An example of a visual effect includes color overlaying. The audio and visual content or the visual effects can be applied to a media content item (e.g., a photo) at the client device 102. For example, the media overlay may include text, a graphical element, or image that can be overlaid on top of a photograph taken by the client device 102. In another example, the media overlay includes an identification of a location overlay (e.g., Venice beach), a name of a live event, or a name of a merchant overlay (e.g., Beach Coffee House). In another example, the augmentation system 208 uses the geolocation of the client device 102 to identify a media overlay that includes the name of a merchant at the geolocation of the client device 102. The media overlay may include other indicia associated with the merchant. The media overlays may be stored in the database 126 and accessed through the database server 120.
In some examples, the augmentation system 208 provides a user-based publication platform that enables users to select a geolocation on a map and upload content associated with the selected geolocation. The user may also specify circumstances under which a particular media overlay should be offered to other users. The augmentation system 208 generates a media overlay that includes the uploaded content and associates the uploaded content with the selected geolocation.
In other examples, the augmentation system 208 provides a merchant-based publication platform that enables merchants to select a particular media overlay associated with a geolocation via a bidding process. For example, the augmentation system 208 associates the media overlay of the highest bidding merchant with a corresponding geolocation for a predefined amount of time. The augmentation system 208 communicates with the image processing server 122 to obtain augmented reality experiences and presents identifiers of such experiences in one or more user interfaces (e.g., as icons over a real-time image or video or as thumbnails or icons in interfaces dedicated for presented identifiers of augmented reality experiences). Once an augmented reality experience is selected, one or more images, videos, or augmented reality graphical elements are retrieved and presented as an overlay on top of the images or video captured by the client device 102. In some cases, the camera is switched to a front-facing view (e.g., the front-facing camera of the client device 102 is activated in response to activation of a particular augmented reality experience) and the images from the front-facing camera of the client device 102 start being displayed on the client device 102 instead of the rear-facing camera of the client device 102. The one or more images, videos, or augmented reality graphical elements are retrieved and presented as an overlay on top of the images that are captured and displayed by the front-facing camera of the client device 102.
In other examples, the augmentation system 208 is able to communicate and exchange data with another augmentation system 208 on another client device 102 and with the server via the network 112. The data exchanged can include a session identifier that identifies the shared AR session, a transformation between a first client device 102 and a second client device 102 (e.g., a plurality of client devices 102 include the first and second devices) that is used to align the shared AR session to a common point of origin, a common coordinate frame, functions (e.g., commands to invoke functions) as well as other payload data (e.g., text, audio, video or other multimedia data).
The augmentation system 208 sends the transformation to the second client device 102 so that the second client device 102 can adjust the AR coordinate system based on the transformation. In this way, the first and second client devices 102 synch up their coordinate systems and frames for displaying content in the AR session. Specifically, the augmentation system 208 computes the point of origin of the second client device 102 in the coordinate system of the first client device 102. The augmentation system 208 can then determine an offset in the coordinate system of the second client device 102 based on the position of the point of origin from the perspective of the second client device 102 in the coordinate system of the second client device 102. This offset is used to generate the transformation so that the second client device 102 generates AR content according to a common coordinate system or frame as the first client device 102.
The augmentation system 208 can communicate with the client device 102 to establish individual or shared AR sessions. The augmentation system 208 can also be coupled to the messaging server 118 to establish an electronic group communication session (e.g., group chat, instant messaging) for the client devices 102 in a shared AR session. The electronic group communication session can be associated with a session identifier provided by the client devices 102 to gain access to the electronic group communication session and to the shared AR session. In one example, the client devices 102 first gain access to the electronic group communication session and then obtain the session identifier in the electronic group communication session that allows the client devices 102 to access the shared AR session. In some examples, the client devices 102 are able to access the shared AR session without aid or communication with the augmentation system 208 in the application servers 114.
The map system 210 provides various geographic location functions, and supports the presentation of map-based media content and messages by the messaging client 104. For example, the map system 210 enables the display of user icons or avatars (e.g., stored in profile data 316) on a map to indicate a current or past location of “friends” of a user, as well as media content (e.g., collections of messages including photographs and videos) generated by such friends, within the context of a map. For example, a message posted by a user to the messaging system 100 from a specific geographic location may be displayed within the context of a map at that particular location to “friends” of a specific user on a map interface of the messaging client 104. A user can furthermore share his or her location and status information (e.g., using an appropriate status avatar) with other users of the messaging system 100 via the messaging client 104, with this location and status information being similarly displayed within the context of a map interface of the messaging client 104 to selected users.
The game system 212 provides various gaming functions within the context of the messaging client 104. The messaging client 104 provides a game interface providing a list of available games (e.g., web-based games or web-based applications) that can be launched by a user within the context of the messaging client 104, and played with other users of the messaging system 100. The messaging system 100 further enables a particular user to invite other users to participate in the play of a specific game, by issuing invitations to such other users from the messaging client 104. The messaging client 104 also supports both voice and text messaging (e.g., chats) within the context of gameplay, provides a leaderboard for the games, and also supports the provision of in-game rewards (e.g., coins and items).
The external resource system 220 provides an interface for the messaging client 104 to communicate with external app(s) servers 110 to launch or access external resources. Each external resource (apps) server 110 hosts, for example, a markup language (e.g., HTML5) based application or small-scale version of an external application (e.g., game, utility, payment, or ride-sharing application that is external to the messaging client 104). The messaging client 104 may launch a web-based resource (e.g., application) by accessing the HTML5 file from the external resource (apps) servers 110 associated with the web-based resource. In certain examples, applications hosted by external resource servers 110 are programmed in JavaScript leveraging a Software Development Kit (SDK) provided by the messaging server 118. The SDK includes Application Programming Interfaces (APIs) with functions that can be called or invoked by the web-based application. In certain examples, the messaging server 118 includes a JavaScript library that provides a given third-party resource access to certain user data of the messaging client 104. HTML5 is used as an example technology for programming games, but applications and resources programmed based on other technologies can be used.
In order to integrate the functions of the SDK into the web-based resource, the SDK is downloaded by an external resource (apps) server 110 from the messaging server 118 or is otherwise received by the external resource (apps) server 110. Once downloaded or received, the SDK is included as part of the application code of a web-based external resource. The code of the web-based resource can then call or invoke certain functions of the SDK to integrate features of the messaging client 104 into the web-based resource.
The SDK stored on the messaging server 118 effectively provides the bridge between an external resource (e.g., third-party or external applications 109 or applets and the messaging client 104). This provides the user with a seamless experience of communicating with other users on the messaging client 104, while also preserving the look and feel of the messaging client 104. To bridge communications between an external resource and a messaging client 104, in certain examples, the SDK facilitates communication between external resource servers 110 and the messaging client 104. In certain examples, a WebViewJavaScriptBridge running on a client device 102 establishes two one-way communication channels between an external resource and the messaging client 104. Messages are sent between the external resource and the messaging client 104 via these communication channels asynchronously. Each SDK function invocation is sent as a message and callback. Each SDK function is implemented by constructing a unique callback identifier and sending a message with that callback identifier.
By using the SDK, not all information from the messaging client 104 is shared with external resource servers 110. The SDK limits which information is shared based on the needs of the external resource. In certain examples, each external resource server 110 provides an HTML5 file corresponding to the web-based external resource to the messaging server 118. The messaging server 118 can add a visual representation (such as a box art or other graphic) of the web-based external resource in the messaging client 104. Once the user selects the visual representation or instructs the messaging client 104 through a GUI of the messaging client 104 to access features of the web-based external resource, the messaging client 104 obtains the HTML5 file and instantiates the resources necessary to access the features of the web-based external resource.
The messaging client 104 presents a graphical user interface (e.g., a landing page or title screen) for an external resource. During, before, or after presenting the landing page or title screen, the messaging client 104 determines whether the launched external resource has been previously authorized to access user data of the messaging client 104. In response to determining that the launched external resource has been previously authorized to access user data of the messaging client 104, the messaging client 104 presents another graphical user interface of the external resource that includes functions and features of the external resource. In response to determining that the launched external resource has not been previously authorized to access user data of the messaging client 104, after a threshold period of time (e.g., 3 seconds) of displaying the landing page or title screen of the external resource, the messaging client 104 slides up (e.g., animates a menu as surfacing from a bottom of the screen to a middle or other portion of the screen) a menu for authorizing the external resource to access the user data. The menu identifies the type of user data that the external resource will be authorized to use. In response to receiving a user selection of an accept option, the messaging client 104 adds the external resource to a list of authorized external resources and allows the external resource to access user data from the messaging client 104. In some examples, the external resource is authorized by the messaging client 104 to access the user data in accordance with an OAuth 2 framework.
The messaging client 104 controls the type of user data that is shared with external resources based on the type of external resource being authorized. For example, external resources that include full-scale external applications (e.g., a third-party or external application 109) are provided with access to a first type of user data (e.g., only two-dimensional avatars of users with or without different avatar characteristics). As another example, external resources that include small-scale versions of external applications (e.g., web-based versions of third-party applications) are provided with access to a second type of user data (e.g., payment information, two-dimensional avatars of users, three-dimensional avatars of users, and avatars with various avatar characteristics). Avatar characteristics include different ways to customize a look and feel of an avatar, such as different poses, facial features, clothing, and so forth.
The AR unboxing system 224 obtains a shared virtual box (e.g., in response to receiving input from a plurality of client devices of a group of users selecting a same AR unboxing experience icon) and presents the shared virtual box (in a closed state, such as with a lock in the locked position) as an overlay or within a real-world environment depicted in a video stream being captured by a front-facing or rear-facing camera of each respective one of the plurality of client devices. In some cases, the AR unboxing system 224 detects that a shared virtual box has been exchanged in a communication session (e.g., a chat session) between a plurality of users. The AR unboxing system 224 receives input from a subset of the users who are engaged and in receipt of the shared virtual box in the communication session. In response, the AR unboxing system 224 launches the shared virtual box unboxing AR experience on client devices of the subset of users who are in the communication session.
The AR unboxing system 224 determines a set or sequence of triggers associated with the shared virtual box which can vary based on certain factors or conditions such that different users are associated with different sequences of triggers for the same AR unboxing experience or shared virtual box. The AR unboxing system 224 then monitors actions performed by the subset of users to determine when the combined actions of the subset of users match or correspond to the sequence of triggers. Once the AR unboxing system 224 determines that the combined actions match or correspond to the sequence of triggers, the AR unboxing system 224 changes the state of the shared virtual box to an open state (e.g., by changing the lock to the unlocked position) and makes the set of contents contained in the shared virtual box available for the subset of users to consume or use. In some cases, the shared virtual box contains a text, audio, or video message that is revealed to all of the users engaged in the communication or chat session in response to the combination of actions received from the client devices 102 of the subset of users matching the sequence of triggers. In this way, the message contained in the shared virtual box remains hidden in the communication or chat interface among other text or audio messages until the subset of users work together to perform actions that match the sequence of triggers associated with the shared virtual box. An illustrative implementation of the AR unboxing system 224 is shown and described in connection with
Specifically, the AR unboxing system 224 is a component that can be accessed by an AR/VR application implemented on the client device 102. The AR/VR application uses an RGB camera to capture a monocular image or video of a real-world environment. The AR/VR application applies various trained machine learning techniques on the captured image or video to apply one or more AR visual effects (e.g., to display a virtual box in a closed or open state) to the captured image. In some implementations, the AR/VR application continuously captures images or a video of the real-world environment in real time or periodically to continuously or periodically update the applied one or more visual effects. This allows the user to move around in the real world and see the one or more visual effects update in real time.
The database 126 includes message data stored within a message table 302. This message data includes, for any particular one message, at least message sender data, message recipient (or receiver) data, and a payload. Further details regarding information that may be included in a message, and included within the message data stored in the message table 302, are described below with reference to
An entity table 306 stores entity data, and is linked (e.g., referentially) to an entity graph 308 and profile data 316. Entities for which records are maintained within the entity table 306 may include individuals, corporate entities, organizations, objects, places, events, and so forth. Regardless of entity type, any entity regarding which the messaging server system 108 stores data may be a recognized entity. Each entity is provided with a unique identifier, as well as an entity type identifier (not shown).
The entity graph 308 stores information regarding relationships and associations between entities. Such relationships may be social, professional (e.g., work at a common corporation or organization) interested-based or activity-based, merely for example.
The profile data 316 stores multiple types of profile data about a particular entity. The profile data 316 may be selectively used and presented to other users of the messaging system 100, based on privacy settings specified by a particular entity. Where the entity is an individual, the profile data 316 includes, for example, a username, telephone number, address, settings (e.g., notification and privacy settings), as well as a user-selected avatar representation (or collection of such avatar representations). A particular user may then selectively include one or more of these avatar representations within the content of messages communicated via the messaging system 100, and on map interfaces displayed by messaging clients 104 to other users. The collection of avatar representations may include “status avatars,” which present a graphical representation of a status or activity that the user may select to communicate at a particular time.
Where the entity is a group, the profile data 316 for the group may similarly include one or more avatar representations associated with the group, in addition to the group name, members, and various settings (e.g., notifications) for the relevant group.
The database 126 also stores augmentation data, such as overlays or filters, in an augmentation table 310. The augmentation data is associated with and applied to videos (for which data is stored in a video table 304) and images (for which data is stored in an image table 312).
The database 126 can also store data pertaining to individual and shared AR sessions. This data can include data communicated between an AR session client controller of a first client device 102 and another AR session client controller of a second client device 102, and data communicated between the AR session client controller and the augmentation system 208. Data can include data used to establish the common coordinate frame of the shared AR scene, the transformation between the devices, the session identifier, images depicting a body, skeletal joint positions, wrist joint positions, feet, and so forth.
Filters, in one example, are overlays that are displayed as overlaid on an image or video during presentation to a recipient user. Filters may be of various types, including user-selected filters from a set of filters presented to a sending user by the messaging client 104 when the sending user is composing a message. Other types of filters include geolocation filters (also known as geo-filters), which may be presented to a sending user based on geographic location. For example, geolocation filters specific to a neighborhood or special location may be presented within a user interface by the messaging client 104, based on geolocation information determined by a Global Positioning System (GPS) unit of the client device 102.
Another type of filter is a data filter, which may be selectively presented to a sending user by the messaging client 104, based on other inputs or information gathered by the client device 102 during the message creation process. Examples of data filters include current temperature at a specific location, a current speed at which a sending user is traveling, battery life for a client device 102, or the current time.
Other augmentation data that may be stored within the image table 312 includes augmented reality content items (e.g., corresponding to applying augmented reality experiences). An augmented reality content item or augmented reality item may be a real-time special effect and sound that may be added to an image or a video.
As described above, augmentation data includes augmented reality content items, overlays, image transformations, AR images, AR logos or emblems, and similar terms that refer to modifications that may be applied to image data (e.g., videos or images). This includes real-time modifications, which modify an image as it is captured using device sensors (e.g., one or multiple cameras) of a client device 102 and then displayed on a screen of the client device 102 with the modifications. This also includes modifications to stored content, such as video clips in a gallery that may be modified. For example, in a client device 102 with access to multiple augmented reality content items, a user can use a single video clip with multiple augmented reality content items to see how the different augmented reality content items will modify the stored clip. For example, multiple augmented reality content items that apply different pseudorandom movement models can be applied to the same content by selecting different augmented reality content items for the content. Similarly, real-time video capture may be used with an illustrated modification to show how video images currently being captured by sensors of a client device 102 would modify the captured data. Such data may simply be displayed on the screen and not stored in memory, or the content captured by the device sensors may be recorded and stored in memory with or without the modifications (or both). In some systems, a preview feature can show how different augmented reality content items will look within different windows in a display at the same time. This can, for example, enable multiple windows with different pseudorandom animations to be viewed on a display at the same time.
Data and various systems using augmented reality content items or other such transform systems to modify content using this data can thus involve detection of objects (e.g., faces, hands, bodies, cats, dogs, surfaces, objects, etc.), tracking of such objects as they leave, enter, and move around the field of view in video frames, and the modification or transformation of such objects as they are tracked. In various examples, different methods for achieving such transformations may be used. Some examples may involve generating a three-dimensional mesh model of the object or objects, and using transformations and animated textures of the model within the video to achieve the transformation. 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 position. In still further examples, neural network analysis of video frames may be used to place images, models, or textures in content (e.g., images or frames of video). Augmented reality content items thus refer both to the images, models, and textures used to create transformations in content, as well as to additional modeling and analysis information needed to achieve such transformations with object detection, tracking, and placement.
Real-time video processing can be performed with any kind of video data (e.g., video streams, video files, etc.) saved in a memory of a computerized system of any kind. For example, a user can load video files and save them in a memory of a device, or can generate a video stream using sensors of the device. Additionally, any objects can be processed using a computer animation model, such as a human's face and parts of a human body, animals, or non-living things such as chairs, cars, or other objects.
In some examples, when a particular modification is selected along with content to be transformed, elements to be transformed are identified by the computing device, and then detected and tracked if they are present in the frames of the video. The elements of the object are modified according to the request for modification, thus transforming the frames of the video stream. Transformation of frames of a video stream can be performed by different methods for different kinds of transformation. For example, for transformations of frames mostly referring to changing forms of an object's elements, characteristic points for each element of an object are calculated (e.g., using an Active Shape Model (ASM) or other known methods). Then, a mesh based on the characteristic points is generated for each of the at least one element of the object. This mesh is used in the following stage of tracking the elements of the object in the video stream. In the process of tracking, the mentioned mesh for each element is aligned with a position of each element. Then, additional points are generated on the mesh. A first set of first points is generated for each element based on a request for modification, and a set of second points is generated for each element based on the set of first points and the request for modification. Then, the frames of the video stream can be transformed by modifying the elements of the object on the basis of the sets of first and second points and the mesh. In such method, a background of the modified object can be changed or distorted as well by tracking and modifying the background.
In some examples, transformations changing some areas of an object using its elements can be performed by calculating characteristic points for each element of an object and generating a mesh based on the calculated characteristic points. Points are generated on the mesh, and then various areas based on the points are generated. The elements of the object are then tracked by aligning the area for each element with a position for each of the at least one element, and properties of the areas can be modified based on the request for modification, thus transforming the frames of the video stream. Depending on the specific request for modification, properties of the mentioned areas can be transformed in different ways. Such modifications may involve changing color of areas; removing at least some part of areas from the frames of the video stream; including one or more new objects into areas which are based on a request for modification; and modifying or distorting the elements of an area or object. In various examples, any combination of such modifications or other similar modifications may be used. For certain models to be animated, some characteristic points can be selected as control points to be used in determining the entire state-space of options for the model animation.
In some examples of a computer animation model to transform image data using face detection, the face is detected on an image with use of a specific face detection algorithm (e.g., Viola-Jones). Then, an Active Shape Model (ASM) algorithm is applied to the face region of an image to detect facial feature reference points.
Other methods and algorithms suitable for face detection can be used. For example, in some examples, features are located using a landmark, which represents a distinguishable point present in most of the images under consideration. For facial landmarks, for example, the location of the left eye pupil may be used. If an initial landmark is not identifiable (e.g., if a person has an eyepatch), secondary landmarks may be used. Such landmark identification procedures may be used for any such objects. In some examples, a set of landmarks forms a shape. Shapes can be represented as vectors using the coordinates of the points in the shape. One shape is aligned to another with a similarity transform (allowing translation, scaling, and rotation) that minimizes the average Euclidean distance between shape points. The mean shape is the mean of the aligned training shapes.
In some examples, a search is started for landmarks from the mean shape aligned to the position and size of the face determined by a global face detector. Such a search then repeats the steps of suggesting a tentative shape by adjusting the locations of shape points by template matching of the image texture around each point and then conforming the tentative shape to a global shape model until convergence occurs. In some systems, individual template matches are unreliable, and the shape model pools the results of the weak template matches to form a stronger overall classifier. The entire search is repeated at each level in an image pyramid, from coarse to fine resolution.
A transformation system can capture an image or video stream on a client device (e.g., the client device 102) and perform complex image manipulations locally on the client device 102 while maintaining a suitable user experience, computation time, and power consumption. The complex image manipulations may include size and shape changes, emotion transfers (e.g., changing a face from a frown to a smile), state transfers (e.g., aging a subject, reducing apparent age, changing gender), style transfers, graphical element application, and any other suitable image or video manipulation implemented by a convolutional neural network that has been configured to execute efficiently on the client device 102.
In some examples, a computer animation model to transform image data can be used by a system where a user may capture an image or video stream of the user (e.g., a selfie) using a client device 102 having a neural network operating as part of a messaging client 104 operating on the client device 102. The transformation system operating within the messaging client 104 determines the presence of a face within the image or video stream and provides modification icons associated with a computer animation model to transform image data, or the computer animation model can be present as associated with an interface described herein. The modification icons include changes that may be the basis for modifying the user's face within the image or video stream as part of the modification operation. Once a modification icon is selected, the transformation system initiates a process to convert the image of the user to reflect the selected modification icon (e.g., generate a smiling face on the user). A modified image or video stream may be presented in a graphical user interface displayed on the client device 102 as soon as the image or video stream is captured, and a specified modification is selected. The transformation system may implement a complex convolutional neural network on a portion of the image or video stream to generate and apply the selected modification. That is, the user may capture the image or video stream and be presented with a modified result in real-time or near real-time once a modification icon has been selected. Further, the modification may be persistent while the video stream is being captured, and the selected modification icon remains toggled. Machine-taught neural networks may be used to enable such modifications.
The graphical user interface, presenting the modification performed by the transformation system, may supply the user with additional interaction options. Such options may be based on the interface used to initiate the content capture and selection of a particular computer animation model (e.g., initiation from a content creator user interface). In various examples, a modification may be persistent after an initial selection of a modification icon. The user may toggle the modification on or off by tapping or otherwise selecting the face being modified by the transformation system and store it for later viewing or browse to other areas of the imaging application. Where multiple faces are modified by the transformation system, the user may toggle the modification on or off globally by tapping or selecting a single face modified and displayed within a graphical user interface. In some examples, individual faces, among a group of multiple faces, may be individually modified, or such modifications may be individually toggled by tapping or selecting the individual face or a series of individual faces displayed within the graphical user interface.
A story table 314 stores data regarding collections of messages and associated image, video, or audio data, which are compiled into a collection (e.g., a story or a gallery). The creation of a particular collection may be initiated by a particular user (e.g., each user for which a record is maintained in the entity table 306). A user may create a “personal story” in the form of a collection of content that has been created and sent/broadcast by that user. To this end, the user interface of the messaging client 104 may include an icon that is user-selectable to enable a sending user to add specific content to his or her personal story.
A collection may also constitute a “live story,” which is a collection of content from multiple users that is created manually, automatically, or using a combination of manual and automatic techniques. For example, a “live story” may constitute a curated stream of user-submitted content from various locations and events. Users whose client devices have location services enabled and are at a common location event at a particular time may, for example, be presented with an option, via a user interface of the messaging client 104, to contribute content to a particular live story. The live story may be identified to the user by the messaging client 104, based on his or her location. The end result is a “live story” told from a community perspective.
A further type of content collection is known as a “location story,” which enables a user whose client device 102 is located within a specific geographic location (e.g., on a college or university campus) to contribute to a particular collection. In some examples, a contribution to a location story may require a second degree of authentication to verify that the end user belongs to a specific organization or other entity (e.g., is a student on the university campus).
As mentioned above, the video table 304 stores video data that, in one example, is associated with messages for which records are maintained within the message table 302. Similarly, the image table 312 stores image data associated with messages for which message data is stored in the entity table 306. The entity table 306 may associate various augmentations from the augmentation table 310 with various images and videos stored in the image table 312 and the video table 304.
Trained machine learning technique(s) 307 stores parameters that have been trained during training of the AR unboxing system 224. For example, trained machine learning techniques 307 stores the trained parameters of one or more neural network machine learning techniques.
Segmentation training images 309 stores a plurality of images that each depict whole-bodies of one or more users in different poses. The plurality of images stored in the segmentation training images 309 includes various depictions of one or more users in different poses together with segmentations of the different poses that indicate which pixels in the images correspond to the whole-body parts and which pixels correspond to a background. Namely the segmentations provide the borders of the whole-bodies of the users depicted in the images. These segmentation training images 309 are used by the AR unboxing system 224 to train the machine learning technique used to generate a segmentation of whole-bodies of users depicted in a received RGB monocular image. In some cases, the segmentation training images 309 include ground truth skeletal key points of one or more whole-bodies depicted in the respective training monocular images. The segmentation training images 309 can include labeled and unlabeled image and video data. The segmentation training images 309 can include a depiction of a whole body of a particular user, an image that lacks a depiction of any user (e.g., a negative image), a depiction of a plurality of users wearing different garments, and depictions of users wearing garments at different distances from an image capture device, such as for a virtual try-on AR experience.
The contents (e.g., values) of the various components of message 400 may be pointers to locations in tables within which content data values are stored. For example, an image value in the message image payload 406 may be a pointer to (or address of) a location within an image table 312. Similarly, values within the message video payload 408 may point to data stored within a video table 304, values stored within the message augmentation data 412 may point to data stored in an augmentation table 310, values stored within the message story identifier 418 may point to data stored in a story table 314, and values stored within the message sender identifier 422 and the message receiver identifier 424 may point to user records stored within an entity table 306.
The virtual box module 510 can receive a list of shared AR unboxing experiences from various users or merchants trying to sell different products. Each box creator (user or merchant) can define the triggers for opening the box and the contents of the box. The box creator can also define the look and feel of the different boxes through an AR platform. The box creator can also define target recipients for the box by specifying attributes associated with the box. The attributes can represent the box contents and/or the level of difficulty of the triggers. Once created, the box creator can upload the AR unboxing experience to the AR unboxing system 224 for inclusion in the list of shared AR unboxing experiences. In some cases, the virtual box module 510 can access a user profile to identify one or more shared AR unboxing experiences that are associated with box attributes that match the user profile. The virtual box module 510 can then select only those identified one or more shared AR unboxing experiences for presentation to a user to select to activate.
The AR unboxing system 224 can request input from the first user that identifies a second user or a plurality of friends. The AR unboxing system 224 communicates with client devices 102 of the second user or the plurality of friends. The AR unboxing system 224 provides an identification of the shared AR unboxing experience selected by the first user. The client devices 102 of the second user or the plurality of friends provide notifications that invite the second user or the plurality of friends to join the shared AR unboxing experience with the first user. In response to receiving input from the client device 102 of the second user accepting the invitation to join the shared AR unboxing experience, the AR unboxing system 224 adds the second user to the shared AR unboxing experience launched by the first user. In one example, the AR unboxing system 224 provides a visual representation (e.g., an avatar, a bitmoji, a floating camera, a floating object, an icon, and so forth) of the second user and any other users who are actively engaged in the same shared AR unboxing experience. In an example, the AR unboxing system 224 presents concurrently on respective client devices 102 of the first and second users a representation of the virtual box the first and second users will try to open together. The virtual box can be presented on respective camera feeds depicting real-world environments being displayed on the client devices 102 of the first and second users.
The virtual box module 510 accesses a database of shared virtual boxes that are currently available to users to open and access. The virtual box module 510 can obtain user profiles of the first and second users of the shared AR unboxing system 224 and search the database to find a virtual box that matches preferences stored in the user profiles. The virtual box module 510 also applies one or more factors (e.g., environmental factors, location, time of day, and so forth) to the database to filter the list of shared virtual boxes to select a particular shared virtual box.
The virtual box module 510 obtains a representation of the particular shared virtual box and instructs the image display module 550 to display the representation of the particular shared virtual box in the closed or locked state on top or within the video stream captured by the respective cameras of the client devices 102 of the first and second users concurrently. In some cases, the first and second users are in the same physical room or location. In some cases, the first and second users are in different physical rooms or locations. The representation can include a box that appears to float in the real-world environment depicted in the video stream or that is placed on top of a real-world object, such as a desk or table. The virtual box module 510 also receives a time limit associated with the particular shared virtual box. The time limit can include a countdown timer during which the particular shared virtual box can be opened. If the shared virtual box is not successfully opened (e.g., by the first and second users performing actions together that in combination correspond to a sequence of triggers associated with the shared virtual box) within the time limit, the shared virtual box remains closed or locked permanently and the set of contents contained in the shared virtual box are discarded. In some cases, a discarded box or box that has been expired and unopened, can be re-presented to the same user or different users at a later time, such as when a re-presentation set of triggers are met. The re-presentation triggers can represent a particular time, day, date, event or other box creator defined trigger.
The virtual box module 510 communicates a unique identifier of the particular shared virtual box (e.g., a unique number and/or type of shared virtual box) to the unboxing trigger module 520. The unboxing trigger module 520 is configured to obtain a sequence of triggers and associate the sequence of triggers with the particular shared virtual box. The sequence of triggers controls access to the virtual box. Namely, the sequence of triggers represents a set of actions that need to be performed in combination by more than one user in sequence or out of sequence in order to change the state of the shared virtual box from a closed state to an open state. In the open state, the set of contents of the virtual box are made available to the users (who performed the combination of actions) to access or consume.
The unboxing trigger module 520 accesses a database that associates different box types, factors, and/or unique identifiers with sequences of triggers.
As an example, the unboxing trigger module 520 can determine that the box type received from the virtual box module 510 matches the box type 1 stored in the box type field 610 of a first entry 630 in the database 600. In response, the unboxing trigger module 520 retrieves a first sequence of triggers stored in the triggers field 620 of the first entry 630. The first sequence of triggers can include a sequence of user actions performed by a group of users, such as a first user shaking, a second user tearing, the first user speaking and twisting, that need to be performed by the first and second users in a particular order. A shake action corresponds to input that shakes a client device 102, such as moving the client device 102 back and forth quickly within a brief specified time interval (e.g., 3 seconds). A tear action corresponds to input that touches or holds two or more portions of a virtual box and moves the portions in opposite directions. A speak action corresponds to voice input that speaks a specified command or response to a challenge question. A twist action corresponds to input that touches or holds a portion of the virtual box and rotates the portion about its axis. The sequence of triggers can include an appearance trigger.
As another example, the unboxing trigger module 520 can determine that a factor (e.g., one or more external factors such as a location of the client device 102, a time of day, a request to record a video of the user interacting with the virtual box being received, weather at the location of the client device 102, or experience level or activeness metric associated with a user, and so forth) received from the virtual box module 510 matches the environmental factor 1 stored in the box type field 610 of a second entry 640 in the database 600. In response, the unboxing trigger module 520 retrieves a second sequence of triggers stored in the triggers field 620 of the second entry 640. The second sequence of triggers can include a sequence of user actions, such as walking along a particular path or responding to a challenge question. The unboxing trigger module 520 can combine the first sequence of triggers with the second sequence of triggers. In one implementation, the unboxing trigger module 520 appends the second sequence of triggers to the first sequence of triggers such that actions in the first sequence of triggers need to be completed before actions in the second sequence. In another implementation, the unboxing trigger module 520 inserts the second sequence of triggers ahead or within the first sequence of triggers.
As another example, the unboxing trigger module 520 can determine that the box type received from the virtual box module 510 corresponds to the shared box type stored in the box type field 610 of a third entry 650. In response, the unboxing trigger module 520 retrieves the sequence of triggers stored in the triggers field 620 of the third entry 650. The sequence of triggers can include any combination of a shared activity, virtual keys, question/answer, body pose matching, puzzle solving, box toss, and/or virtual tools. The shared activity trigger can define a particular activity a group of users need to perform to achieve a common goal. Once the unboxing trigger module 520 determines that the common goal (e.g., solving a puzzle or riddle) has been successfully reached by each of the group of users, the unboxing trigger module 520 can determine that the shared activity trigger is satisfied.
An appearance trigger can instruct the user to perform an action to change an appearance of the user. For example, the appearance trigger can instruct the user to find a fashion item (e.g., hat, sunglasses, article of clothing, jewelry, and so forth) and to wear the fashion item. The appearance trigger can provide a time limit for the user to change the appearance in the specified way. The appearance trigger can perform object recognition of a captured video feed to detect whether the change in appearance matches the specified instructions. For example, if the appearance trigger includes an instruction for the user to wear sunglasses, the appearance trigger can apply object recognition to detect presence of sunglasses in a predetermined proximity of the face of the user. In response to detecting the object associated with the instruction in the video feed within the specified time limit, the appearance trigger determines that the trigger has been satisfied.
The virtual keys trigger can define one or more virtual keys that need to be inserted into a virtual location on the shared virtual box. The virtual location can be marked on the shared virtual box or hidden. Once each user in the group of users inserts their respective virtual keys in the correct location on the shared virtual box, the unboxing trigger module 520 can determine that the virtual keys trigger is satisfied. The question/answer trigger can define a question that is received from a first user and an answer to the question also received from the first user. The question is presented to a second user and a response is received from the second user. The unboxing trigger module 520 can determine that the response matches the answer received from the first user and, in response, the unboxing trigger module 520 can determine that the question/answer trigger is satisfied. The body pose matching trigger can define a particular whole-body pose that needs to be performed by the first and second users or group of users attempting to open the virtual box. The unboxing trigger module 520 can determine when images of the first and second users depict the users performing the same pose that matches the particular whole-body pose and, in response, the unboxing trigger module 520 determines that the body pose matching trigger is satisfied.
The box toss trigger can define a number of times that the virtual box is moved or tossed between a group of users. Each time the virtual box is virtually moved along a direction of a given user by another user, the unboxing trigger module 520 increments a current count value. In response to determining that the current count value matches the number of times defined by the box toss trigger, the unboxing trigger module 520 determines that the trigger is satisfied. The virtual tools trigger can define one or more virtual tools that need to be used or applied to the virtual box (e.g., a chisel, a hose spraying water, a shovel, a hammer, an ax, and so forth). When a certain combination of virtual tools is performed a certain number of times by the group of users using their respective virtual tools, the unboxing trigger module 520 can determine that the virtual tools are satisfied.
In some implementations, the unboxing trigger module 520 communicates the obtained sequence of triggers to the input detection module 530 and to the virtual box module 510. In one example, the virtual box module 510 displays hints or representations of the obtained sequence of triggers to the first and second users who are engaged in the same shared virtual box AR session or experience. In some examples, the hints or representations can be displayed when there is a threshold amount of time remaining on the time limit associated with the shared virtual box. For example, the virtual box module 510 can determine that the countdown timer has reached a specified value (e.g., 5 minutes remaining). In such cases, the virtual box module 510 can display some or all of the obtained sequence of triggers that have not yet been completed or a representation or hint corresponding to the obtained sequence of triggers.
The input detection module 530 monitors user actions performed on the client devices 102 of each of the users who are engaged in the shared virtual box opening AR experience while the shared virtual box is being displayed in the closed state on top of or within a real-world environment depicted in a video stream on the respective client devices 102. The input detection module 530 can access the obtained sequence of triggers. The input detection module 530 retrieves a first trigger that is in the sequence of triggers. The input detection module 530 determines that the first trigger is associated with a first user. In response, the input detection module 530 monitors the user actions performed on the client device 102 of the first user to determine when a particular user action corresponds to the first trigger. For example, the first trigger can be a shake gesture. The input detection module 530 can monitor actions performed on the client device 102 by the first user interacting with the virtual box that is being displayed in the closed state. The input detection module 530 can detect that the client device 102 of the first user is being shaken and, in response, the input detection module 530 can determine that the first trigger has been satisfied. It should be understood that the words “triggers” and “conditions” are interchangeable and should be understood to have the same meaning. Once the first trigger or condition is satisfied, the input detection module 530 displays an indicator on the displays of the first and second users on their respective client devices 102 informing the users of the progress in opening the shared virtual box. Specifically, initially a progress bar can be displayed with 0% completion status or 0/5 (if there are 5 triggers set) being shown. In response to determining that the first trigger has been completed, the progress bar can be updated to show 25% or more depending on the number of triggers that remain. This way, the users are informed as to how many more actions remain and how close the users are to opening the shared virtual box.
The input detection module 530 accesses the sequence of triggers to obtain a next trigger that is in the sequence. The input detection module 530 determines that the next trigger is associated with a second user. In response, the input detection module 530 monitors the user actions performed on the client device 102 of the second user to determine when a particular user action corresponds to the second trigger. For example, the second trigger can be a tear gesture. The input detection module 530 can monitor actions performed on the client device 102 by the second user interacting with the shared virtual box that is being displayed in the closed state on the multiple client devices 102. The input detection module 530 can detect that input received from the client device 102 of the second user corresponds to a tear action and, in response, the input detection module 530 can determine that the second trigger has been satisfied.
In some examples, the input detection module 530 detects that a current trigger that is retrieved from the sequence of triggers corresponds to a matching pose trigger. In such cases, the input detection module 530 obtains a target pose from the current trigger. The input detection module 530 instructs each of the client devices 102 of the first and second users (who are actively trying to work together to open a shared virtual box) to present a message that depicts the target pose and instructs the users to perform a whole-body pose that matches the target pose. The input detection module 530 can capture a first image of the first user via the client device 102 of the first user in response to receiving input from the first user indicating that the first user completed performing the target pose. Concurrently, before or after, the input detection module 530 can capture a second image of the second user via the client device 102 of the second user in response to receiving input from the second user indicating that the second user completed performing the target pose. The input detection module 530 communicates the first and second images to the body pose segmentation module 560 together with the target pose.
The body pose segmentation module 560 applies one or more trained machine learning techniques on the first and second images to generate first and second whole-body segmentations of the first and second users depicted respectively in the first and second images. The body pose segmentation module 560 can then adjust scales of the first and second whole-body segmentations to match. For example the body pose segmentation module 560 computes a scale of the first image and increases or reduces a scale of the second whole-body segmentation to match the scale of the first image. The body pose segmentation module 560 aligns the first and second whole-body segmentations on top of each other after scaling one or both of the whole-body segmentations. The body pose segmentation module 560 computes how many pixels overlap in the aligned whole-body segmentations. In response to determining that a threshold quantity or number of pixels overlap, the body pose segmentation module 560 compares one or both of the whole-body segmentations to the target pose. In response to determining that one or both of the whole-body segmentations match the target pose, the body pose segmentation module 560 determines that the matching pose trigger is satisfied and communicates this indication to the input detection module 530.
In some examples, the input detection module 530 detects that a current trigger that is retrieved from the sequence of triggers corresponds to a virtual keys trigger. In response, the input detection module 530 displays a virtual key on one or both of the client devices 102 of the first and second users. The input detection module 530 determines a mapping between each virtual key and a virtual location on the virtual box. The input detection module 530 determines when input received from a user of one of the client devices 102 moves a particular virtual key towards a given location on the virtual box. The input detection module 530 determines that the given location of the virtual key matches the mapped virtual location associated with the virtual key. In such cases, the input detection module 530 determines that the particular virtual key has been correctly placed on the virtual box. After determining that each of the virtual keys has been moved by user input to a position associated with the virtual key on the virtual box, the input detection module 530 determines that the virtual keys trigger is satisfied.
In some examples, the input detection module 530 detects that a current trigger that is retrieved from the sequence of triggers corresponds to a virtual tools trigger. In response, the input detection module 530 displays a plurality of virtual tools on one or both of the client devices 102 of the first and second users. The input detection module 530 determines a mapping between each virtual tool and one or more virtual locations on the virtual box along with a quantity. The input detection module 530 determines when input received from a user of one of the client devices 102 moves a particular virtual tool (selected from the plurality of virtual tools) towards a given location on the virtual box. The input detection module 530 determines that the given location of the virtual tool matches the mapped virtual location associated with the virtual tool. In such cases, the input detection module 530 determines that the particular virtual tool has been correctly placed on the virtual box and monitors how many times an action request associated with the virtual tool is received (e.g., how many times a user presses an apply option for the virtual tool). Once the virtual tool has been applied to one or more assigned locations on the virtual box a threshold quantity of times, the input detection module 530 determines that a portion of the trigger associated with the virtual tool has been satisfied. The input detection module 530 requests that the other user apply a different virtual tool to the virtual box. The input detection module 530 determines when the different virtual tool is moved by the other user to a specified location on the virtual box and is applied a threshold quantity of times. In such cases, the input detection module 530 determines that another portion of the trigger has been satisfied. After determining that each of the virtual tools has been moved by user input received from respective client devices 102 of the first and second users to an assigned position associated with the virtual tool on the virtual box and has been applied a respective threshold quantity of times, the input detection module 530 determines that the virtual tools trigger is satisfied.
In some examples, the input detection module 530 detects that a current trigger that is retrieved from the sequence of triggers corresponds to a box toss trigger. In such cases, the input detection module 530 can receive input from a first client device 102 of a first user that pushes, throws, or tosses the virtual box towards a direction of a virtual representation (or location) of a second user. In response, the input detection module 530 increments a counter. The input detection module 530 then receives input from a second client device 102 of the second user that pushes, throws or tosses the virtual box back towards a direction of the virtual representation (or location) of the first user. In response, the input detection module 530 increments the counter again. The input detection module 530 determines when a current count value of the counter reaches a specified value or threshold. In response to determining that the current count value of the counter reaches the specified value or threshold, the input detection module 530 determines that the box toss trigger is satisfied.
In some examples, the input detection module 530 detects that a current trigger that is retrieved from the sequence of triggers corresponds to an online game. The input detection module 530 launches the game on the respective client devices 102 of the first and second users. The input detection module 530 monitors the progress of the game to determine which of the first and second users is the winner. In response to determining that the second user is the winner of the game, the input detection module 530 automatically assigns some or all of the set of contents contained in the virtual box to the second user. For example, after the virtual box is opened in response to the first and second users completing actions that correspond to the sequence of triggers, the box content selection module 540 selects a particular one or portion of the set of contents to only make available to the second user and prevent the first user from accessing the particular one or portion of the set of contents. In one example, the box content selection module 540 generates an NFT for the particular one or portion of the set of contents and assigns the NFT to an account or address of the second user. This transfers ownership rights to the second user and prevents the first user from obtaining access privileges to the particular one or portion of the set of contents.
The input detection module 530 determines if the currently obtained trigger is a last trigger in the sequence of triggers. In response to determining that the currently obtained trigger is the last trigger in the sequence, the input detection module 530 continues monitoring user actions to determine when the user actions correspond to the currently obtained trigger and instructs the client devices 102 of the first and second users (who are in the shared virtual unboxing session) to activate front-facing cameras of the client devices 102. Specifically, while the users are together performing the last action (or while one of the users associated with the last action is performing the last action) needed to open the shared virtual box, a recording of a video of each user's face is captured by their respective cameras. In some cases, the input detection module 530 instructs the client devices 102 to only begin recording the users' faces when the input detection module 530 determines that the user(s) performed an action that corresponds to the last trigger in the sequence. In this case, the input detection module 530 instructs the client devices 102 to concurrently or simultaneously (at the same time) record or capture videos of the faces of the first and second users concurrently while instructing the unboxing trigger module 520 to modify a state of the shared virtual box from the closed state to the open state. As part of modifying the state of the shared virtual box from the closed state to the open state, the unboxing trigger module 520 animates the shared virtual box as opening, such as by animating opening a door or entry into the virtual box that is displayed. In this way, the reactions of the first and second users can be automatically captured while unveiling or revealing the set of contents of the shared virtual box. The videos can then be shared with one or more other users, such as in a communication session.
In an example, in response to determining that a combination of actions received from the plurality of client devices 102 associated with the plurality of users in the shared AR unboxing experience matches the sequence of triggers, the input detection module 530 causes the virtual box to change from the closed state to the open state. In this case, the input detection module 530 communicates with the box content selection module 540 and the image display module 550 to animate the virtual box on the plurality of client devices 102 concurrently as opening or changing to the open state. The box content selection module 540 obtains preferences from the user profiles of the plurality of users. The box content selection module 540 identifies a plurality of shared preferences and searches available content or object inventory to identify a set of contents that match the shared preferences of the plurality of users. The box content selection module 540 adds the set of contents to the shared virtual box or associates the set of contents with the shared virtual box such that when the shared virtual box is opened or changes to the open state, the set of contents are revealed and presented concurrently to the plurality of users on their respective client devices 102.
In some examples, the virtual box module 510 provides an interface that enables a first user to create a virtual box and define the sequence of triggers for opening the virtual box. The client device 102 of the first user can receive input from the first user that selects a set of contents to include in the virtual box, such as a text, video and/or audio message. The client device 102 of the first user can also request the first user to specify a sequence of triggers to associate with the virtual box. The client device 102 can present a list of available triggers and the first user can select any number and combination of triggers from the list. The client device 102 can also allow the first user to define a time limit to associate with the shared virtual box. The client device 102 of the first user can receive input from the first user to share the virtual box with a group of users engaged in a group communication session or interface. In response, the virtual box module 510 receives input from the first user that specifies the group of recipients. The virtual box module 510 sends the shared virtual box to the specified recipients, such as to their respective messaging clients 104 implemented on their respective client device 102. The client devices 102 of the specified recipients receive the shared virtual box via the messaging client 104 and display a representation of the shared virtual box in line or between a group of other messages exchanged in the communication session. The specified recipients can select the representation of the shared virtual box to launch the virtual box AR experience to work together to perform a sequence of actions corresponding to the triggers associated with the shared virtual box to reveal the set of contents of the virtual box. Once the set of contents is revealed, the representation of the shared virtual box in the communication session or interface is replaced with the set of contents (e.g., the text, audio or video message) that was contained in the shared virtual box.
In some examples, the virtual box module 510 can receive input or a request to repackage the virtual box after the virtual box changes states from the closed state to the open state. In response, the virtual box module 510 can animate the virtual box as closing and display the virtual box in the closed state. The virtual box module 510 communicates an indication to the unboxing trigger module 520 that the same box has been repackaged. In response, the unboxing trigger module 520 can modify the sequence of triggers associated with the virtual box, such as to increase a complexity of the actions that need to be performed to open the virtual box. In such cases, the unboxing trigger module 520 accesses the database 600 to obtain a trigger from the triggers field 620 that corresponds to a repacking factor stored in the box type field 610. The unboxing trigger module 520 inserts the obtained trigger into a random location or a specified location (e.g., the start or end) of the sequence of triggers previously associated with the virtual box. In this way, the users can experience reopening the same virtual box with a different level of difficulty.
The AR unboxing system 224 can receive input from the first user that selects a second user to join the first user in performing actions to open the shared virtual box 710. The AR unboxing system 224 communicates with a second client device 102 of the second user to enable the second user to join the shared virtual unboxing AR experience 730 with the first user. In response to receiving input from the second client device 102 indicating that the second user accepts the invitation to join, the AR unboxing system 224 adds the second user to the shared virtual unboxing AR experience 730. Particularly, the AR unboxing system 224 activates a rear-facing camera of the second client device 102 and displays the same shared virtual box 710 as an augmented reality element in the real-world environment depicted in the video feed received from the rear-facing camera of the second client device 102. The AR unboxing system 224 also presents a representation 740 of the second user in the user interface 700 of the first client device 102 to inform the first user about the users who are currently engaged in the shared virtual unboxing AR experience 730.
The AR unboxing system 224 can also determine that the virtual box 710 is associated with a time limit. In such cases, the AR unboxing system 224 displays the countdown timer 720 indicating how much time is left for the users in the shared virtual unboxing AR experience 730 to perform the sequence of actions together that match the triggers for opening the shared virtual box 710. In some cases, although not shown, the AR unboxing system 224 can also present a progress bar indicating or representing how many of the triggers have currently been successfully performed and how many triggers remain.
The AR unboxing system 224 can monitor actions performed by the first user on the first client device 102 and the second user on the second client device 102. The AR unboxing system 224 can determine that the sequence of actions performed by the first and second users in combination correspond to the sequence of triggers associated with the shared virtual box 710. The AR unboxing system 224 can, in response, modify a state of the shared virtual box 710 from being in a closed state to being in an open state. For example, in the user interface 800 shown in
In some examples, the set of contents 820 includes virtual articles of clothing or garments. The AR unboxing system 224 can receive input from the first user that selects a particular one of the virtual articles of clothing. In response, the AR unboxing system 224 can present a try-on option 830 and can receive input that selects the try-on option 830. In this case, the AR unboxing system 224 launches or activates a virtual try-on AR experience in which a front-facing or rear-facing camera is used to capture a depiction of the first user and is augmented with the selected virtual articles of clothing. Namely, the AR unboxing system 224 can present or overlay the virtual articles of clothing on top of a depiction of the first user so the first user can visualize how the user looks wearing the virtual articles of clothing. The AR unboxing system 224 also presents the depiction of the first user wearing the virtual articles of clothing to the second user who was involved in opening the shared virtual box 810.
The AR unboxing system 224 can present an option to purchase the real-world clothing corresponding to the virtual articles of clothing being tried on. In response to receiving input selecting the option to purchase, the AR unboxing system 224 completes an e-commerce transaction to purchase the real-world clothing from an online merchant to have the real-world clothing delivered physically to the first user. In some cases, the real-world clothing can be purchased at a discount in response to the users successfully performing the sequence of actions that correspond to the triggers associated with opening the shared virtual box 810.
The communication interface 850 can receive input from the second user and the third user (users B and C) that select the icon 860 from their respective client devices 102. In response, the communication interface 850 launches a shared AR virtual unboxing experience on the client devices 102 of the second and third users. The AR unboxing system 224 monitors inputs received from the second and third users (indicative of actions performed by the second and third users on their respective client devices 102) to determine when a combination of the inputs match the sequence of triggers associated with the virtual box. In some examples, the AR unboxing system 224 presents a video showing a real-time feed to the first user who generated the virtual box representing the interactions of the second and third users with the virtual box. This allows the first user to see the progress being made by the second and third users in opening the virtual box in real-time. In some cases, the progress bar associated with the shared AR virtual unboxing experience is shared with the first user and is updated as the second and third users perform actions that satisfy the triggers in the sequence of triggers.
In response to determining that the combination of the inputs match the sequence of triggers associated with the virtual box, the AR unboxing system 224 changes the state of the virtual box from the closed state to the open state to reveal the message contained in the box. In an implementation, the AR unboxing system 224 navigates the second and third users back to the communication interface 850 on their respective client devices 102. The AR unboxing system 224 can replace the icon 860 of the virtual box in the closed state with the message generated by the first user on the client device 102 of the first user. This reveals the contents of the virtual box within the communication interface 850.
At operation 901, the AR unboxing system 224 (e.g., a client device 102 or a server) causes concurrent display of a shared augmented reality experience comprising a shared virtual box that is in a closed state on a plurality of client devices associated with a plurality of users, as discussed above. For example, the AR unboxing system 224 obtains an augmented reality element that includes a shared virtual box 710 and displays the shared virtual box 710 in the user interface 700 of each of a plurality of client devices 102 that are engaged or that have joined the shared AR unboxing experience (
At operation 902, the AR unboxing system 224 obtains a sequence of triggers associated with the shared virtual box, the sequence of triggers configured to change the shared virtual box from the closed state to an open state, as discussed above. For example, the AR unboxing system 224 accesses a database that associates different box types with sequences of triggers to obtain the sequence of triggers associated with the shared virtual box 710.
At operation 903, the AR unboxing system 224 receives, from a first client device of the plurality of client devices, first input associated with the shared virtual box, as discussed above. For example, the AR unboxing system 224 monitors user interactions or user actions with the box on a first client device 102, such as shaking or twisting.
At operation 904, the AR unboxing system 224 receives, from a second client device of the plurality of client devices, second input associated with the shared virtual box, as discussed above. For example, the AR unboxing system 224 monitors user interactions or user actions with the box on a second client device 102, such as tearing or speaking.
At operation 905, the AR unboxing system 224 determines that the first and second inputs received from the first and second client devices correspond to the sequence of triggers associated with the shared virtual box, as discussed above. For example, the AR unboxing system 224 determines that the sequence of user actions received in combination from the first and second client devices 102 matches or corresponds to the sequence of triggers obtained and associated with the shared virtual box 710.
At operation 906, the AR unboxing system 224 modifies the shared virtual box from being displayed on the plurality of devices in the closed state to being displayed in the open state in response to determining that the first and second inputs correspond to the sequence of triggers associated with the shared virtual box, as discussed above. For example, the AR unboxing system 224 modifies the shared virtual box 710 from being in the closed state to depict the virtual box 810 (

The rear cameras may, for example, be used to capture still images and videos in a more traditional camera mode, with these images similarly being augmented with augmentation data. In addition to front and rear cameras, the client device 102 may also include a 360° camera for capturing 360° photographs and videos.
Further, the camera system of a client device 102 may include dual rear cameras (e.g., a primary camera as well as a depth-sensing camera), or even triple, quad or penta rear camera configurations on the front and rear sides of the client device 102.

Similarly, the instructions 1008 may be transmitted or received using a transmission medium via a coupling (e.g., a peer-to-peer coupling) to the devices 1022.
The operating system 1112 manages hardware resources and provides common services. The operating system 1112 includes, for example, a kernel 1114, services 1116, and drivers 1122. The kernel 1114 acts as an abstraction layer between the hardware and the other software layers. For example, the kernel 1114 provides memory management, processor management (e.g., scheduling), component management, networking, and security settings, among other functionality. The services 1116 can provide other common services for the other software layers. The drivers 1122 are responsible for controlling or interfacing with the underlying hardware. For instance, the drivers 1122 can include display drivers, camera drivers, BLUETOOTH® or BLUETOOTH® Low Energy drivers, flash memory drivers, serial communication drivers (e.g., USB drivers), WI-FI® drivers, audio drivers, power management drivers, and so forth.
The libraries 1110 provide a common low-level infrastructure used by applications 1106. The libraries 1110 can include system libraries 1118 (e.g., C standard library) that provide functions such as memory allocation functions, string manipulation functions, mathematic functions, and the like. In addition, the libraries 1110 can include API libraries 1124 such as media libraries (e.g., libraries to support presentation and manipulation of various media formats such as Moving Picture Experts Group-4 (MPEG4), Advanced Video Coding (H.264 or AVC), Moving Picture Experts Group Layer-3 (MP3), Advanced Audio Coding (AAC), Adaptive Multi-Rate (AMR) audio codec, Joint Photographic Experts Group (JPEG or JPG), or Portable Network Graphics (PNG)), graphics libraries (e.g., an OpenGL framework used to render in two dimensions (2D) and three dimensions (3D) in a graphic content on a display), database libraries (e.g., SQLite to provide various relational database functions), web libraries (e.g., WebKit to provide web browsing functionality), and the like. The libraries 1110 can also include a wide variety of other libraries 1128 to provide many other APIs to the applications 1106.
The frameworks 1108 provide a common high-level infrastructure that is used by the applications 1106. For example, the frameworks 1108 provide various graphical user interface (GUI) functions, high-level resource management, and high-level location services. The frameworks 1108 can provide a broad spectrum of other APIs that can be used by the applications 1106, some of which may be specific to a particular operating system or platform.
In an example, the applications 1106 may include a home application 1136, a contacts application 1130, a browser application 1132, a book reader application 1134, a location application 1142, a media application 1144, a messaging application 1146, a game application 1148, and a broad assortment of other applications such as an external application 1140. The applications 1106 are programs that execute functions defined in the programs. Various programming languages can be employed to create one or more of the applications 1106, structured in a variety of manners, such as object-oriented programming languages (e.g., Objective-C, Java, or C++) or procedural programming languages (e.g., C or assembly language). In a specific example, the external application 1140 (e.g., an application developed using the ANDROID™ or IOS™ software development kit (SDK) by an entity other than the vendor of the particular platform) may be mobile software running on a mobile operating system such as IOS™, ANDROID™, WINDOWS® Phone, or another mobile operating system. In this example, the external application 1140 can invoke the API calls 1150 provided by the operating system 1112 to facilitate functionality described herein.
“Carrier signal” refers to any intangible medium that is capable of storing, encoding, or carrying instructions for execution by the machine, and includes digital or analog communications signals or other intangible media to facilitate communication of such instructions. Instructions may be transmitted or received over a network using a transmission medium via a network interface device.
“Client device” refers to any machine that interfaces to a communications network to obtain resources from one or more server systems or other client devices. A client device may be, but is not limited to, a mobile phone, desktop computer, laptop, portable digital assistants (PDAs), smartphones, tablets, ultrabooks, netbooks, laptops, multi-processor systems, microprocessor-based or programmable consumer electronics, game consoles, set-top boxes, or any other communication device that a user may use to access a network.
“Communication network” refers to one or more portions of a network that may be an ad hoc network, an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a wireless WAN (WWAN), a metropolitan area network (MAN), the Internet, a portion of the Internet, a portion of the Public Switched Telephone Network (PSTN), a plain old telephone service (POTS) network, a cellular telephone network, a wireless network, a Wi-Fi® network, another type of network, or a combination of two or more such networks. For example, a network or a portion of a network may include a wireless or cellular network and the coupling may be a Code Division Multiple Access (CDMA) connection, a Global System for Mobile communications (GSM) connection, or other types of cellular or wireless coupling. In this example, the coupling may implement any of a variety of types of data transfer technology, such as Single Carrier Radio Transmission Technology (1×RTT), Evolution-Data Optimized (EVDO) technology, General Packet Radio Service (GPRS) technology, Enhanced Data rates for GSM Evolution (EDGE) technology, third Generation Partnership Project (3GPP) including 3G, fourth generation wireless (4G) networks, Universal Mobile Telecommunications System (UMTS), High Speed Packet Access (HSPA), Worldwide Interoperability for Microwave Access (WiMAX), Long Term Evolution (LTE) standard, others defined by various standard-setting organizations, other long-range protocols, or other data transfer technology.
“Component” refers to a device, physical entity, or logic having boundaries defined by function or subroutine calls, branch points, APIs, or other technologies that provide for the partitioning or modularization of particular processing or control functions. Components may be combined via their interfaces with other components to carry out a machine process. A component may be a packaged functional hardware unit designed for use with other components and a part of a program that usually performs a particular function of related functions.
Components may constitute either software components (e.g., code embodied on a machine-readable medium) or hardware components. A “hardware component” is a tangible unit capable of performing certain operations and may be configured or arranged in a certain physical manner. In various examples, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware components of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware component that operates to perform certain operations as described herein.
A hardware component may also be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware component may include dedicated circuitry or logic that is permanently configured to perform certain operations. A hardware component may be a special-purpose processor, such as a field-programmable gate array (FPGA) or an application specific integrated circuit (ASIC). A hardware component may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, a hardware component may include software executed by a general-purpose processor or other programmable processor. Once configured by such software, hardware components become specific machines (or specific components of a machine) uniquely tailored to perform the configured functions and are no longer general-purpose processors. It will be appreciated that the decision to implement a hardware component mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software), may be driven by cost and time considerations. Accordingly, the phrase “hardware component” (or “hardware-implemented component”) should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein.
Considering examples in which hardware components are temporarily configured (e.g., programmed), each of the hardware components need not be configured or instantiated at any one instance in time. For example, where a hardware component comprises a general-purpose processor configured by software to become a special-purpose processor, the general-purpose processor may be configured as respectively different special-purpose processors (e.g., comprising different hardware components) at different times. Software accordingly configures a particular processor or processors, for example, to constitute a particular hardware component at one instance of time and to constitute a different hardware component at a different instance of time.
Hardware components can provide information to, and receive information from, other hardware components. Accordingly, the described hardware components may be regarded as being communicatively coupled. Where multiple hardware components exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) between or among two or more of the hardware components. In examples in which multiple hardware components are configured or instantiated at different times, communications between such hardware components may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware components have access. For example, one hardware component may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware component may then, at a later time, access the memory device to retrieve and process the stored output. Hardware components may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information).
The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented components that operate to perform one or more operations or functions described herein. As used herein, “processor-implemented component” refers to a hardware component implemented using one or more processors. Similarly, the methods described herein may be at least partially processor-implemented, with a particular processor or processors being an example of hardware. For example, at least some of the operations of a method may be performed by one or more processors 1002 or processor-implemented components. Moreover, the one or more processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines including processors), with these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., an API). The performance of certain of the operations may be distributed among the processors, not only residing within a single machine, but deployed across a number of machines. In some examples, the processors or processor-implemented components may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other examples, the processors or processor-implemented components may be distributed across a number of geographic locations.
“Computer-readable storage medium” refers to both machine-storage media and transmission media. Thus, the terms include both storage devices/media and carrier waves/modulated data signals. The terms “machine-readable medium,” “computer-readable medium” and “device-readable medium” mean the same thing and may be used interchangeably in this disclosure.
“Ephemeral message” refers to a message that is accessible for a time-limited duration. An ephemeral message may be a text, an image, a video and the like. The access time for the ephemeral message may be set by the message sender. Alternatively, the access time may be a default setting or a setting specified by the recipient. Regardless of the setting technique, the message is transitory.
“Machine storage medium” refers to a single or multiple storage devices and media (e.g., a centralized or distributed database, and associated caches and servers) that store executable instructions, routines and data. The term shall accordingly be taken to include, but not be limited to, solid-state memories, and optical and magnetic media, including memory internal or external to processors. Specific examples of machine-storage media, computer-storage media and device-storage media include non-volatile memory, including by way of example semiconductor memory devices, e.g., erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), FPGA, and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks The terms “machine-storage medium,” “device-storage medium,” “computer-storage medium” mean the same thing and may be used interchangeably in this disclosure. The terms “machine-storage media,” “computer-storage media,” and “device-storage media” specifically exclude carrier waves, modulated data signals, and other such media, at least some of which are covered under the term “signal medium.”
“Non-transitory computer-readable storage medium” refers to a tangible medium that is capable of storing, encoding, or carrying the instructions for execution by a machine.
“Signal medium” refers to any intangible medium that is capable of storing, encoding, or carrying the instructions for execution by a machine and includes digital or analog communications signals or other intangible media to facilitate communication of software or data. The term “signal medium” shall be taken to include any form of a modulated data signal, carrier wave, and so forth. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a matter as to encode information in the signal. The terms “transmission medium” and “signal medium” mean the same thing and may be used interchangeably in this disclosure.
Changes and modifications may be made to the disclosed examples without departing from the scope of the present disclosure. These and other changes or modifications are intended to be included within the scope of the present disclosure, as expressed in the following claims.
