The present disclosure relates to eyewear devices.

Some electronics-enabled eyewear devices, such as so-called smart glasses, allow users to interact with virtual content while they engage in some activity. Users can wear the eyewear devices and view a real-world environment through the eyewear devices while interacting with virtual content displayed by the eyewear devices.

The description that follows discusses exemplary embodiments of the present disclosure. In the following description, for purposes of explanation, numerous specific details are set forth to provide an understanding of various embodiments of the disclosed subject matter. However, it will be apparent to those skilled in the art that embodiments of the disclosed subject matter may be practiced without these specific details. In general, well-known instruction instances, protocols, structures, and techniques have not necessarily been shown in detail.

Typical smart glasses platforms allow users to read their text messages within the smart glasses as well as interact with other types of virtual content. These platforms are configured to display virtual content in the lenses of smart glasses. While these systems generally work well to allow users to interact with virtual content, these devices do not account for the user's movement through the real-world environment in the display of virtual content. Some systems continue to display virtual content as the user moves around the real-world environment, but doing so is not always meaningful and can end up flooding the user with too much information, making such presentation counterproductive. . That is, these devices do not selectively decide whether or not to continue displaying virtual content within the current view of the real-world environment as the user moves around, which, in turn, frustrates the user and eventually leads the user to what they are doing. distract from activities.

Also, the typical way of presenting virtual content in the lenses of smart glasses ends up consuming a lot of processing and battery resources. This is because these devices process virtual content using standard, resource-intensive programming languages and operations, and further use additional resources to create this virtual content for display. As a result, the battery life of these typical smart glasses is very limited, requiring the user to constantly charge the smart glasses for use, which detracts from the attractiveness and interest in using them.

The disclosed embodiments improve the efficiency of using an electronic device by selectively updating a virtual location where virtual content is displayed by the electronic eyewear device, such as based on receipt of a specific request. The user is notified of the virtual content as the user moves around the real-world environment in a non-intrusive manner. Specifically, the virtual content is displayed at the first virtual location when the user views the first portion of the real-world environment through the eyewear device. The virtual content remains in the first virtual location to be removed from the display of the eyewear device as the user moves around to view the second portion of the real-world environment. The virtual content is moved to be displayed again and brought back into view while the user views the second portion of the real-world environment in response to a specific request to bring one or more virtual objects into the current view of the eyewear device. A specific request may be received from the user, such as by tapping or long-pressing on the touch input interface of the eyewear device or performing a physical gesture using a body part of the user (eg, the user's hands). can A specific request may also be received from an application associated with the virtual objects, indicating that an update associated with the virtual objects is received. This avoids distractions and impedes the user from performing activities while interacting with the virtual content.

Battery life of the electronic eyewear device is enhanced because the processor of the eyewear device executes a low-power process to selectively view virtual objects displayed within a real-world environment. This increases the efficiency, attractiveness, and usefulness of electronic eyewear devices.

Networked Computing Environment

1 is a block diagram illustrating an exemplary messaging system 100 for exchanging data (eg, messages and associated content) over a network. Messaging system 100 includes multiple instances of client device 102, each including messaging client 104 and other external applications 109 (eg, third-party applications). hosts applications. Each messaging client 104 connects to other instances of the messaging client 104 (eg, hosted on each of the other client devices 102) and to the network 112 (eg, the Internet). communicatively connected to the messaging server system 108 and external app(s) servers 110 via Messaging client 104 may also communicate with locally-hosted third-party applications 109 using Applications Program Interfaces (APIs). Messaging system 100 includes eyewear device 119 , which hosts, among other applications, content centering system 107 . Eyewear device 119 is communicatively coupled to client device 102 via network 112 (which may include via a dedicated short-range communication path such as Bluetooth ^™ or WiFi direct connection).

The content centering system 107 automatically or selectively moves augmented reality or virtual reality content from one virtual location to another as the user moves around the eyewear device 119 . For example, a user or wearer of eyewear device 119 may be initially viewing a first portion of the real-world environment (eg, a first room in a house). A user may provide input (e.g., using a voice activated or touch activated interface of client device 102 or eyewear device 119) to launch or access virtual content that includes one or more objects. there is. Specifically, a user may request access to a music or video library. In response, a list of thumbnails or visual indicators of media assets associated with the music or video library within the view of the first portion of the real-world environment is retrieved and presented.

In an example, the content centering system 107 assigns the first virtual location to the virtual content. The first virtual location corresponds to a location in three-dimensional space where the first portion of the real-world environment exists. The content centering system 107 displays the virtual content at a first virtual location such that the virtual content is visible to the user when the user views the first portion of the real-world environment through the lenses of the eyewear device 119 . In one case, the virtual content includes user interface elements for controlling the playback of the content. In these cases, the user can interact with the virtual content to play, pause, skip or control consumption of the media assets. In other cases, virtual content includes user interface elements for generating augmented reality content. In such cases, the user may interact with the virtual content to add augmented reality items or elements to the view of eyewear device 119 (e.g., the user via eyewear device 119 may interact with the user). You can add virtual paint to the real-world scene you are viewing).

While media assets are being played and displayed in a first virtual location, the user may turn their head or walk to another real-world location (eg, another room in the house, a second part of the real-world environment). there is. The other real-world location may include some or none of the real-world objects within view of the first portion of the real-world location. The virtual content displayed in the first virtual location remains in that location while the user moves around. As a result, the virtual content disappears from view when the user is viewing the second portion of the real-world environment.

Content centering system 107 may receive a request to bring virtual content into the current view of eyewear device 119 . For example, the user may tap or long press on the touch interface of the eyewear device 119 to request that virtual content be brought into the current view. As another example, a user may perform a hand gesture or foot gesture that is captured by a camera of eyewear device 119 . In response to determining that the hand or foot gesture matches the predetermined movement, the content centering system 107 determines that a request to retrieve virtual content in the current view has been received. In another example, the content centering system 107 may receive a request to bring the virtual content into a current view from an application associated with the virtual content. Specifically, the application may indicate that one of the virtual objects associated with the virtual content includes an update (eg, a new message in a conversation may be received, and playback of a given playlist or media asset may be delayed). terminated, etc.). In such cases, the update may request the content centering system 107 to bring the virtual content into the current view of the eyewear device 119 .

In response to receiving a request to bring virtual content into the current view of eyewear device 119 , content centering system 107 identifies a second virtual location that is within the current view of the lenses of eyewear device 119 . The content centering system 107 updates the virtual location of the virtual content from the first virtual location to the second virtual location and then displays the virtual content at the second virtual location. In this way, virtual content that was not in view of the eyewear device 119 because the user has moved around does not enter the current view (eg, is displayed within the view of the second portion of the real-world environment). . This allows the user to continue interacting with the virtual content when needed.

In some cases, a user can perform a gesture or provide a command to cause virtual content to be continuously and continuously displayed within the view of eyewear device 119 (e.g., eyewear device 119 ) can be long pressed on the touch interface). In these situations, the virtual location of the virtual content is continuously updated to be displayed to the user on the lenses of the eyewear device 119 as the user moves around the real-world environment. When the user stops performing the gesture (eg, when releasing a finger from the touch interface), the virtual content is frozen in its current virtual location and is no longer updated or moved while the user moves around. That is, when the gesture is stopped, the virtual content remains at the last virtual position. At this point, it disappears from view as the user moves around the virtual content (eg, if the user turns 180 degrees and the virtual content is behind the user, the virtual content is not displayed within the lenses of the eyewear device 119). . This is because the user is now viewing a different part of the real-world environment that is not within view of the last virtual location of the virtual content.

Messaging client 104 can communicate and exchange data with other messaging clients 104 , with eyewear device 119 , and with messaging server system 108 over network 112 . Data exchanged between messaging clients 104 and between messaging client 104 and messaging server system 108 includes functions (eg, commands to invoke functions) as well as payload data (eg, For example, text, audio, video or other multimedia data).

Messaging server system 108 provides server-side functionality to specific messaging clients 104 over network 112 . While certain functions of messaging system 100 are described herein as being performed by messaging client 104 or by messaging server system 108, certain functionalities within messaging client 104 or messaging server system 108 Location may be a design option. For example, it is technically desirable to initially deploy certain technology and functionality within messaging server system 108, but later migrate such technology and functionality to messaging client 104 where client device 102 has sufficient processing capacity. can do.

Messaging server system 108 supports various services and operations provided to messaging clients 104 . These operations include sending data to the messaging client 104, receiving data therefrom, and processing data generated thereby. Such data may include, as examples, message content, client device information, geolocation information, media enhancements and overlays, message content persistence conditions, social network information, and live event information. Data exchanges within the messaging system 100 are initiated and controlled through functions available through the user interfaces (UIs) of the messaging client 104 .

Referring now to the messaging server system 108 in detail, an application program interface (API) server 116 is coupled to the application servers 114 and provides a programmatic interface to them. Application servers 114 are communicatively coupled to database server 120, which facilitates access to database 126 that stores data associated with messages processed by application servers 114. Similarly, web server 128 is coupled to application servers 114 and provides web-based interfaces to application servers 114 . To this end, web server 128 handles incoming network requests via Hypertext Transfer Protocol (HTTP) and some other related protocols.

An application program interface (API) server 116 receives and transmits message data (eg, commands and message payloads) between the client device 102 and the application servers 114 . Specifically, application program interface (API) server 116 provides interfaces (e.g., routines and protocols). Application Program Interface (API) server 116 is responsible for account registration, login functionality, transfer of messages from a particular messaging client 104 to another messaging client 104, via application servers 114, messaging client 104 ) to the messaging server 118, the transfer of media files (eg, images or videos), and the establishment of a collection of media data (eg, stories) for possible access by other messaging clients 104. , searching the list of friends of the user of client device 102, searching these collections, searching messages and content, adding entities (eg friends) to an entity graph (eg social graph), and Expose various functions supported by application servers 114, including deleting, location of friends in the social graph, and opening application events (eg, related to messaging client 104).

Application servers 114 host a number of server applications and subsystems, including, for example, messaging server 118 , image processing server 122 , and social network server 124 . Messaging server 118 processes multiple messages, particularly related to the aggregation and other processing of content (e.g., text and multimedia content) included in messages received from multiple instances of messaging client 104. Implement technologies and functionalities. As described in further detail, text and media content from multiple sources can be aggregated into collections of content (eg, called stories or galleries). Next, these collections are made available to the messaging client 104. Other processor- and memory-intensive processing of data may also be performed server-side by messaging server 118, taking into account the hardware requirements for such processing.

Application servers 114 are dedicated image processing server 122 to perform various image processing operations, typically with respect to images or video within the payload of messages sent to or received from messaging server 118 . ) is also included.

Image processing server 122 is used to implement the scanning functionality of augmented system 208 . The scanning functionality includes activating and providing one or more augmented reality experiences on the client device 102 when an image is captured by the client device 102 . Specifically, the messaging application 104 on the client device 102 can be used to activate the camera. The camera displays one or more real-time images or videos to the user along with one or more icons or identifiers of one or more augmented reality experiences. A user may select a given one of the identifiers to launch a corresponding augmented reality experience. Launching the augmented reality experience includes obtaining one or more augmented reality items associated with the augmented reality experience and overlaying the augmented reality items over the images or video being presented.

Social network server 124 supports various social networking function functions and services and makes these functions and services available to messaging server 118 . To this end, social network server 124 maintains and accesses entity graph 308 (shown in FIG. 3 ) in database 126 . Examples of functions and services supported by social network server 124 include identification of other users of messaging system 100 that a particular user has relationships with or “following”, and also identification of other entities. and interests of particular users.

Returning to the messaging client 104 , features and functions of an external resource (eg, a third party application 109 or applet) are made available to the user through the interface of the messaging client 104 . Messaging client 104 receives user selection of an option to launch or access features of external resources (eg, third-party resources), such as external apps 109 . An external resource is a third party application (external apps 109) installed on the client device 102 (eg, a “native app”), or on or on the client device 102. ) may be a small-scale version (eg, an “applet”) of a third-party application hosted remotely (eg, on third-party servers 110). A small-scale version of a third party application includes a subset of the features and functions of the third party application (eg, a full-scale, native version of a third party independent application) and contains a markup-language document. implemented using In one example, the small-scale version (eg, “applet”) of the third-party application 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 (eg, .*ml files), applets may use scripting languages (eg, .*js files or .json files) and stylesheets (eg, .*ml files). ss file).

In response to receiving a user selection of an option to launch an external resource (external app 109) or access its features, messaging client 104 determines whether the selected external resource is a web-based external resource or locally- Determines whether it is an installed external application. In some cases, external applications 109 that are installed locally on the client device 102 can be accessed by selecting an icon on the home screen of the client device 102, corresponding to the external application 109, and As such, it may be launched independently and separately from the messaging client 104 . Small-scale versions of these external applications may be launched or accessed through the messaging client 104, and in some instances, no portions of the small-scale external application may or may not be accessible outside of the messaging client 104. Or, restricted portions may be accessed. The small-scale external application may be launched by the messaging client 104, which receives, from the external app(s) server 110, markup-language documents associated with the small-scale external application and processes these documents.

In response to determining that the external resource is a locally-installed external application 109, the messaging client 104 launches the external application 109 by executing locally-stored code corresponding to the external application 109. command the client device 102 to do or access. 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. Next, the messaging client 104 processes the obtained markup-language document to present the web-based external resource within the user interface of the messaging client 104 .

Messaging client 104 can notify the user of client device 102, or other users related to the user (eg, “friends”), of activity occurring on one or more external resources. For example, messaging client 104 may send participants of a conversation (eg, a chat session) at messaging client 104 notifications related to current or recent use of an external resource by one or more members of a group of users. can provide One or more users may be invited to join an active external resource or launch a recently used but currently inactive external resource (in a group of friends). The external resource provides the participants in the conversation, each using a respective messaging client messaging client messaging client 104, an item, status, state, or location on the external resource entering the chat session. You can provide the ability to share with one or more members of a group of users. A shared item may be an interactive chat card with which members of the chat interact, for example to launch a corresponding external resource, view specific information in the external resource, or move members of the chat to specific information in the external resource. It can take you to a location or state. Within a given external resource, response messages can be sent to users on the messaging client 104. The external resource can optionally include different media items in the responses based on the external resource's current context.

Messaging client 104 may present a list of available external resources (eg, third party or external applications 109 or applets) to the user for launching or accessing a given external resource. Such a list can be presented in a context-sensitive menu. For example, icons representing different ones of external applications 109 (or applets) may change based on how the menu is launched by the user (eg, from an interactive interface or from a non-interactive interface). .

system architecture

2 is a block diagram illustrating additional details regarding the messaging system 100, in accordance with some examples. Specifically, the messaging system 100 is shown as including a messaging client 104 and application servers 114 . Messaging system 100 implements a number of subsystems, supported on the client side by messaging client 104 and on the server side by application servers 114 . These subsystems include, for example, short-term timer system 202, collection management system 204, augmentation system 208, map system 210, game system 212, and external resource system 220. do.

Short-term timer system 202 is responsible for enforcing temporary or time-limited access to content by messaging client 104 and messaging server 118 . The short-lived timer system 202 determines (eg, a story) for messages and associated content via the messaging client 104 based on duration and display parameters associated with a message or collection of messages (eg, a story). , a number of timers that selectively enable access (for presentation and display). Additional details regarding the operation of the short term timer system 202 are provided below.

Collection management system 204 is responsible for managing sets or collections of media (eg, collections of text, image video, and audio data). A collection of content (eg, messages, including images, video, text, and audio) can be organized into an "event gallery" or "event story." Such a collection may be made available for a specified period of time, such as the duration of an event to which the content relates. For example, content related 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 in the user interface of the messaging client 104 to provide notification of the existence of a particular collection.

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 related to a specific event (eg, delete inappropriate content or duplicate messages). Additionally, the collection management system 204 automatically curates the content collection using machine vision (or image recognition technology) and content rules. In certain instances, a reward for including user-generated content in a collection may be paid to the user. In such cases, the collection management system 204 operates to automatically pay these users for the use of their content.

The augmentation system 208 provides various functions that enable a user to augment (eg, annotate or otherwise revise or edit) media content associated with a message. For example, augmentation system 208 provides functionality related to the creation and publication of media overlays for messages processed by messaging system 100 . Augmentation system 208 operatively supplies media overlays or augmentations (eg, image filters) to messaging client 104 based on the geolocation of client device 102 . In another example, augmentation system 208 operatively supplies media overlays to messaging client 104 based on other information, such as social network information of a user of client device 102 . A media overlay can include audible and visual content and visual effects. Examples of audio and visual content include pictures, texts, logos, animations, and sound effects. Examples of visual effects include color overlays. Audible and visual content or visual effects may be applied to media content items (eg, photos) on the client device 102 . For example, a media overlay may include text, graphic elements, or images that may be overlaid over a picture taken by client device 102 . In another example, the media overlay includes an overlay of an identification of a location (eg, Venice beach), a name of a live event, or an overlay of the name of a vendor (eg, Beach Coffee House). In another example, augmentation system 208 uses the geolocation of client device 102 to identify a media overlay that includes the name of a merchant at the geolocation of client device 102 . The media overlay may include other indicia associated with the merchant. Media overlays are stored in database 126 and can be accessed via database server 120 .

In some examples, augmentation system 208 provides a user-based publishing platform that enables users to select a geolocation on a map and upload content associated with the selected geolocation. A user may also specify situations in which a particular media overlay should be presented to other users. The augmentation system 208 creates a media overlay that includes the uploaded content and associates the uploaded content with the selected geolocation.

In other examples, augmentation system 208 provides a merchant-based public platform that enables merchants to select a specific media overlay associated with a geolocation through a bidding process. For example, the augmentation system 208 associates the media overlay of the highest bidding merchant with the corresponding geolocation for a predefined amount of time. Augmented system 208 communicates with image processing server 122 to obtain augmented reality experiences, and displays identifiers of these experiences in one or more user interfaces (eg, as icons over a real-time image or video or as augmented reality experiences). as thumbnails or icons in interfaces dedicated to the presented identifiers). Once an augmented reality experience is selected, one or more images, videos, or augmented reality graphical elements are retrieved and presented as overlays over the image or video captured by the client device 102 . In some cases, the camera is switched to a front view (eg, the front camera of client device 102 is activated in response to activation of a particular augmented reality experience), and the images from the front camera of client device 102 are It begins to be displayed on the client device 102 instead of the rear camera of the client device 102 . One or more images, videos, or augmented reality graphical elements are retrieved and presented as an overlay over the images captured and displayed by the front-facing camera of the client device 102 .

Map system 210 provides various geolocation capabilities and supports presentation of map-based media content and messages by messaging client 104 . For example, the map system 210 may, within the context of a map, view the current or historical locations of the user's “friends,” as well as media content (eg, photos and videos) created by those friends. It enables the display of user icons or avatars (eg, stored in profile data 316) on the map to display collections of messages that contain. For example, a message posted by a user to messaging system 100 from a specific geographic location may be sent to the specific user's "friends" on a map interface of messaging client 104 within the context of a map at that specific location. can be displayed. A user may further share his or her location and status information (eg, using an appropriate status avatar) with other users of the messaging system 100 via the messaging client 104, such location and status The information is similarly displayed within the context of the map interface of messaging client 104 to selected users.

Gaming system 212 provides various gaming functions within the context of messaging client 104 . Messaging client 104 can play available games (eg, web-based games or web games) that can be launched by a user within the context of messaging client 104 and played with other users of messaging system 100. -provides a game interface that presents a list of base applications). Messaging system 100 further enables a particular user to invite other users to participate in play of a specific game by issuing invitations to these other users from messaging client 104 . Messaging client 104 also supports both voice and text messaging (eg, chats) within the context of gameplay, provides a leaderboard for games, and provides in-game rewards. (eg, coins and items) is also supported.

External resource system 220 provides an interface for messaging client 104 to communicate with external app(s) servers 110 to launch or access external resources. Each external resource (apps) server 110 is, for example, a markup language (eg, HTML5) based application or an external application (eg, a game, utility, external to the messaging client 104, payment, or ride-sharing applications). Messaging client 104 may launch a web-based resource (eg, application) by accessing an HTML5 file from 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 utilizing a Software Development Kit (SDK) provided by messaging server 118 . The SDK includes Application Programming Interfaces (APIs) with functions that can be invoked or called by web-based applications. In certain examples, messaging server 118 includes a JavaScript library that provides a given third party resource access to specific user data of messaging client 104 . HTML5 is used as an example technology for programming games, but applications and resources programmed based on other technologies may be used.

To integrate the functions of the SDK into a web-based resource, the SDK is downloaded by the External Resources (Apps) Server 110 from the Messaging Server 118 or otherwise received by the External Resources (Apps) Server 110 . Once downloaded or received, the SDK is included as part of the application code of a web-based external resource. Code in the web-based resource can then invoke or invoke specific functions of the SDK to incorporate features of the messaging client 104 into the web-based resource.

The SDK stored on messaging server 118 effectively provides a bridge between external resources (eg, third party or external applications 109 or applets) and 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 communication between the external resource and the messaging client 104, in certain examples, the SDK facilitates communication between the external resource servers 110 and the messaging client 104. In certain examples, a WebViewJavaScriptBridge running on client device 102 establishes two unidirectional communication channels between an external resource and messaging client 104 . Messages are sent asynchronously between the external resource and the messaging client 104 over these communication channels. Each SDK function activation 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.

Using the SDK, not all information from messaging clients 104 is shared with external resource servers 110 . The SDK limits what information is shared based on the needs of external resources. In certain examples, each external resource server 110 provides the messaging server 118 with an HTML5 file corresponding to a web-based external resource. Messaging server 118 may add visual representations of web-based external resources (such as box art or other graphics) to messaging client 104 . Once the user selects a visual representation or commands the messaging client 104 through the GUI of the messaging client 104 to access features of the web-based external resource, the messaging client 104 obtains the HTML5 file; Instantiate the resources needed to access the features of a web-based external resource.

Messaging client 104 presents a graphical user interface (eg, landing page or title screen) for external resources. During, before, or after presenting the landing page or title screen, messaging client 104 determines whether the launched external resource has previously been authorized to access user data of messaging client 104 . In response to determining that the launched external resource was previously authorized to access user data of the messaging client 104, the messaging client 104 displays another graphical user interface of the external resource that includes functions and features of the external resource. presents After a threshold period (eg, 3 seconds) of displaying the external resource's landing page or title screen in response to determining that the launched external resource was not previously authorized to access user data of the messaging client 104. , the messaging client 104 slides up a menu to authorize external resources to access user data (eg, animates the menu as it floats from the bottom of the screen to the middle or other portion of the screen). This menu identifies the type of user data that the external resource is authorized to use. In response to receiving the user selection of the accept option, the messaging client 104 adds the external resource to the list of authorized external resources and allows the external resource to access user data from the messaging client 104 . In some examples, an external resource is authorized by messaging client 104 to access user data according to the OAuth 2 framework.

Messaging client 104 controls the type of user data shared with external resources based on the type of external resource being authorized. For example, external resources including full-scale external applications (eg, third party or external application 109) may include user data of a first type (eg, with or without different avatar characteristics). access is provided to only two-dimensional avatars of non-users. As another example, external resources including small-scale versions of external applications (eg, web-based versions of third-party applications) may contain user data of a second type (eg, payment information, user 2-dimensional avatars of users, 3-dimensional avatars of users, and avatars with various avatar characteristics) are provided. Avatar characteristics include different ways to customize the look and feel of an avatar, such as different poses, facial features, clothing, and the like.

data architecture

3 is a schematic diagram illustrating data structures 300 that may be stored in the database 126 of the messaging server system 108, according to certain examples. Although the content of database 126 is shown as including a number of tables, it will be appreciated that data may be stored in other types of data structures (eg, as an object-oriented database).

Database 126 includes message data stored in message table 302 . Such message data includes, for any particular one message, at least message sender data, message recipient (or receiver) data, and payload. Additional details regarding the information included in the message and that may be included within the message data stored in the message table 302 are described below with reference to FIG. 4 .

Entity table 306 stores entity data and is linked (eg, for reference) to entity graph 308 and profile data 316 . Entities for which records are maintained in entity table 306 may include individuals, corporate entities, organizations, objects, places, events, and the like. Regardless of the entity type, any entity for which 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).

Entity graph 308 stores information about relationships and associations between entities. These relationships may be social, professional (eg, work in a common legal entity or organization) interest-based or activity-based, by way of example only.

Profile data 316 stores multiple types of profile data about a particular entity. Profile data 316 may optionally be used and presented to other users of messaging system 100 based on privacy settings specified by a particular entity. If the entity is an individual, profile data 316 may include, for example, user name, phone number, address, settings (eg, notification and privacy settings), as well as a user-selected avatar representation (or such collection of avatar expressions). A particular user then optionally includes one or more of these avatar representations within the content of messages communicated through messaging system 100 and on map interfaces displayed to other users by messaging clients 104. can do. The collection of avatar representations may include “status avatars,” which present a graphical representation of a state or activity that a user may choose to communicate with at a particular time.

If the entity is a group, profile data 316 for the group similarly includes one or more avatar representations associated with the group, in addition to the group name, members, and various settings (eg, notifications) for the associated group. can include

Database 126 also stores augmentation data, such as overlays or filters, in augmentation table 310 . Augmented data is associated with and applied to videos (of which data is stored in video table 304 ) and images (of which data is stored in image table 312 ).

In one example, filters are overlays that are displayed as being overlaid on an image or video during presentation to a recipient user. The filters may be of various types, including user-selected filters from a set of filters presented to the 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) that can be presented to a sending user based on geographic location. For example, geolocation filters specific to a neighborhood or particular location may be presented within a user interface by messaging client 104 based on geolocation information determined by a Global Positioning System (GPS) unit of client device 102. It can be.

Another type of filter is a data filter, which may be selectively presented to the sending user by the messaging client 104 based on information gathered by the client device 102 during the message creation process or other inputs. Examples of data filters include the current temperature at a specific location, the current rate at which the sending user is traveling, the battery life for the client device 102, or the current time of day.

Other augmented data that may be stored within image table 312 includes augmented reality content items (eg, corresponding to applying augmented reality experiences). Augmented reality content items or augmented reality items can be real-time special effects and sounds that can be added to images or video.

As described above, augmented data is a similar term that refers to augmented reality content items, overlays, image transformations, AR images, and modifications that can be applied to image data (eg, videos or images). include them This is captured using device sensors (eg, one or multiple cameras) of client device 102 and then modifies the image as it is displayed on the screen of client device 102 along with the modifications. , including real-time modifications. This also includes modifications to stored content, such as video clips in a gallery that can be modified. For example, on a client device 102 having access to multiple augmented reality content items, a user can use a single video clip with multiple augmented reality content items to know how to modify a clip in which different augmented reality content items are stored. can find out whether For example, multiple augmented reality content items that apply different pseudo-random movement models can be applied to the same content by selecting different augmented reality content items for the content. Similarly, real-time video capture can be used with the illustrated modification to show how the video images currently being captured by the sensors of the client device 102 will modify the captured data. This data may simply be displayed on the screen and not stored in memory, or the content captured by the device sensors may be written and stored in memory with or without modifications (or both). In some systems, the preview feature can show how different augmented reality content items will appear simultaneously in different windows on the display. This may enable, for example, multiple windows with different pseudo-random animations to be shown simultaneously on a display.

Accordingly, data and various systems that use augmented reality content items or other such transformation systems to modify content using such data may be used to modify objects (e.g., faces, hands, bodies, cats, dogs, surfaces objects, objects, etc.), tracking of these objects as they leave, enter, and move around the field of view in video frames, and modify or transform these objects as they are tracked. . In various examples, different methods may be used to achieve these transformations. Some examples may involve creating a three-dimensional mesh model of an object or objects, and using such model's transforms and animated textures within the video to achieve the transform. In other examples, tracking of points on an object may be used to place an image or texture (which may be 2-dimensional or 3-dimensional) at the tracked location. In still other examples, neural network analysis of video frames can be used to place images, models, or textures in content (eg, images or frames of video). Thus, augmented reality content items are both the images, models, and textures used to create transformations in the content, as well as the additional modeling and analysis information necessary to achieve these transformations with object detection, tracking, and placement. refers to

Real-time video processing can be performed with any kind of video data (eg, video streams, video files, etc.) stored in the memory of any kind of computerized system. For example, a user can load video files and store them in the device's memory, or use the device's sensors to create a video stream. Additionally, certain objects may be processed using the computer animation model, such as human faces and body parts, animals, or inanimate objects such as chairs, cars, or other objects.

In some examples, when a particular modification is selected along with the content to be transformed, the elements to be transformed are identified by the computing device and then detected and tracked if they are present in frames of the video. 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, which primarily refer to changing the shapes of elements of an object, specific points for each element of an object (e.g., using the Active Shape Model (ASM) or other known methods) using) is calculated. Next, a mesh based on points unique to each of the at least one element of the object is created. This mesh is used in the next step 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 the position of each element. Next, additional points are created on the mesh. A first set of first points is created for each element based on the request for modification, and a second set of points is created for each element based on the first set of points and the request for modification. Next, frames of the video stream may be transformed by modifying elements of the object based on the first and second sets of points and the mesh. In this way, the background of the modified object can be changed or distorted as well by tracking and modifying the background.

In some examples, transformations that use elements of an object to change some areas thereof may be performed by calculating characteristic points for each element of the object and generating a mesh based on the computed characteristic points. . Points are created on the mesh, and then various regions are created based on these points. The elements of the object are then tracked by aligning the region for each element with the position for each of the at least one element, and the properties of these regions may be modified based on the request for modification, thus the quality of the video stream. transform the frames. Depending on the specific request for modification, the characteristics of the areas mentioned may be transformed in different ways. These modifications include changing the color of regions; removing at least some portions of the regions from frames of the video stream; including one or more new objects in areas based on the request for modification; and modifying or distorting elements of the area or object. In various examples, any combination of these or other similar modifications may be used. For specific models to be animated, some specific points can be selected as control points to be used in determining the overall state-space of options for model animation.

In some examples of computer animation models that transform image data using face detection, faces are detected on images using specific face detection algorithms (eg Viola-Jones). Next, an Active Shape Model (ASM) algorithm is applied to the face region of the image to detect facial feature reference points.

Other methods and algorithms suitable for face detection may be used. For example, in some examples, features are located using landmarks representing distinguishable points present in most of the images under consideration. For facial landmarks, for example, the location of the left eye pupil may be used. If the initial landmark is not identifiable (eg, the person has an eyepatch), secondary landmarks can be used. These landmark identification procedures may be used for any of these objects. In some examples, a set of landmarks forms a shape. Shapes can be represented as vectors using the coordinates of points on the shape. One shape is aligned to another shape using a similarity transformation (allowing translation, scaling, and rotation) that minimizes the average Euclidean distance between shape points. The average shape is the average of the aligned training shapes.

In some examples, a search is initiated for landmarks from an average shape aligned to the position and size of the face determined by the global face detector. This search then proposes a temporary shape by adjusting the positions of the shape points by template matching of the image texture around each point and then fitting the temporary shape to the overall shape model until convergence occurs. repeat In some systems, individual template matches are unreliable, and the shape model pools the results of weak template matches to form a stronger overall classifier. The full search is repeated at each level in the image pyramid, from coarse to fine resolution.

The conversion system captures an image or video stream on a client device (e.g., client device 102) and complex image locally on the client device 102 while maintaining acceptable user experience, computing time, and power consumption. operations can be performed. Complex image manipulations include size and shape changes, emotion transitions (e.g., changing a face from a frown to a smile), state transitions (e.g., aging a subject, reducing apparent age, changing gender). changes), style transitions, graphical element applications, and any other suitable image or video manipulation implemented by a convolutional neural network configured to run efficiently on client device 102 .

In some examples, a computer animation model for transforming image data can be used to convert an image or image of a user using a client device 102 having a neural network operating as part of a messaging client 104 in which the user operates on the client device 102. It can be used by systems capable of capturing video streams (eg selfies). A transformation system operating within the messaging client 104 determines the presence of a face in an image or video stream and provides modification icons associated with a computer animation model to transform the image data, or the computer animation model described herein. It can exist as something associated with an interface that is. Modify icons include changes that may be the basis for modifying a user's face within an image or video stream as part of a retouch operation. Once the correction icon is selected, the transformation system begins the process of transforming the user's image (eg, creating a smiling face on the user) to reflect the selected correction icon. The 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 the specified modification is selected. The transformation system may implement a complex convolutional neural network over a portion of an image or video stream to generate and apply selected modifications. That is, a user can capture an image or video stream and be presented with the modified result in real-time or near real-time once the edit icon is selected. Additionally, the modification can be ongoing while the video stream is being captured and the selected modification icon remains toggled. Machine-trained neural networks can be used to enable these modifications.

A graphical user interface, presenting the modifications performed by the conversion system, may provide additional interaction options to the user. These options may be based on the interface used to initiate content capture and selection of a particular computer animation model (eg, from a content creator user interface). In various examples, the modification may be ongoing after the initial selection of the modification icon. The user can toggle the modification on or off by tapping or otherwise selecting the face being modified by the transformation system and save it for later viewing or browsing to other areas of the shooting application. there is. If multiple faces are modified by the conversion system, the user can toggle the modification on or off as a whole by tapping or selecting a single face that is modified and displayed within the graphical user interface. In some examples, among a group of multiple faces, individual faces may be individually modified or such modifications may be individually toggled by tapping or selecting an individual face or series of individual faces displayed within a graphical user interface. It can be.

The story table 314 stores data relating to collections of messages and associated image, video or audio data, which are compiled into a collection (eg, a story or gallery). Creation of a particular collection may be initiated by a particular user (eg, each user for whom a record is maintained in the entity table 306). A user can create a "personal story" in the form of a collection of content created and transmitted/broadcast by that user. To this end, the user interface of the messaging client 104 may include a user-selectable icon to enable the sending user to add specific content to his or her personal story.

A collection may also constitute a “live story,” which is a collection of content from multiple users created manually, automatically, or using a combination of manual and automated techniques. For example, a “live story” can constitute a curated stream of user-submitted content from various locations and events. Users whose client devices enable location services and who are at a common location event at a particular time may be presented with the option to contribute content to a particular live story, for example, via the user interface of the messaging client 104. there is. 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.

An additional type of content collection is a "location story" that enables users whose client devices 102 are located within a specific geographic location (eg, college or university campus) to contribute to a specific collection. )" is known. In some examples, contributions 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 (eg, is a student on a college campus).

As noted above, video table 304 stores, in one example, video data associated with messages for which records are maintained in message table 302 . Similarly, image table 312 stores image data associated with messages for which message data is stored in entity table 306 . Entity table 306 can associate various enhancements from augmentation table 310 with various images and videos stored in image table 312 and video table 304 .

4 is a schematic diagram illustrating the structure of a message 400 generated by a messaging client 104 for communication to a further messaging client 104 or messaging server 118, according to some examples. The content of a particular message 400 is used to populate a message table 302 stored in a database 126, accessible by the messaging server 118. Similarly, the content of message 400 is stored in memory as “in-transit” or “in-flight” data of client device 102 or application servers 114 .

Message enhancement data 412: Augmentation data representing enhancements to be applied to the message image payload 406, message video payload 408, or message audio payload 410 of the message 400 (e.g., filter fields, stickers, or other annotations or enhancements). Augmentation data for sent or received messages 400 may be stored in augmentation table 310 .

Message duration parameter 414: for which the contents of the message (e.g., message image payload 406, message video payload 408, message audio payload 410) are passed through the messaging client 104 A parameter value indicating the amount of time, in seconds, to be presented or made accessible to the user.

Message geolocation parameter 416: Geolocation data (eg, latitude and longitude coordinates) associated with the message's content payload. A number of message geolocation parameter 416 values can be included in the payload, each of which is a content (e.g., a specific image in the message image payload 406, or a specific image in the message video payload 408). associated with respect to content items included in a specific video).

Message story identifier 418: One or more content collections (e.g., “stories” identified in story table 314) to which a particular content item in message image payload 406 of message 400 is associated.

Message tag 420: Each message 400 may be tagged with a number of tags, each indicating a subject of content included in the message payload. For example, when a specific image included in the message image payload 406 depicts an animal (eg, a lion), a tag value indicating a related animal may be included in the message tag 420 . Tag values can be manually generated, based on user input, or automatically generated using, for example, image recognition.

Message sender identifier 422: An identifier indicating the user of the client device 102 on which the message 400 was created and from which the message 400 was sent (e.g., a messaging system identifier, email address, or device identifier). ).

The contents (eg, values) of the various components of message 400 may be pointers to locations in a table within which content data values are stored. For example, the image value in the message image payload 406 can be a pointer to (or its address) a location in the image table 312 . Similarly, values within message video payload 408 may point to data stored within video table 304 and values stored within message augmented data 412 may point to data stored in augmented table 310. values stored in message story identifier 418 may point to data stored in story table 314, and values stored in message sender identifier 422 and message receiver identifier 424 may point to entity table 306 may point to user records stored in it.

In other embodiments, one or both of the optical elements may be a display, a display assembly, or a lens and display combination.

Frame 506 includes a pair of end pieces 521 defining lateral end portions of frame 506 . In this example, various electronics components are housed in one or both of the end pieces 521 . Temples 509 are connected to respective end pieces 521 . In this example, the temples 509 are hinged between a collapsed mode and a wearable mode in which the temples 509 are pivoted towards the frame 506 such that the temples 509 lie substantially flat with respect to the frame. It is movably connected to the frame 506 by respective hinges. In another embodiment, temples 509 may be connected to frame 506 by any suitable means, or may be rigidly or rigidly secured to frame 506 to be integral therewith.

Temples 509 each include a front portion that connects to frame 506 and any suitable rear portion for connecting to a user's ear, such as curves or cute pieces illustrated in the exemplary embodiment of FIG. 5 . do. In some embodiments, frame 506 is formed from a single piece of material to have a unitary or monolithic construction. In some embodiments, the entirety of body 503 (including both frame 506 and temples 509) may be of a single or monolithic construction.

Eyewear device 119 is an onboard electronics component comprising a computing device, such as computer 524 or low power processor, which in different embodiments may be of any suitable type to be carried by body 503. have them In some embodiments, computer 524 is at least partially housed in one or both temples 509 . In this embodiment, various components of computer 524 are housed in lateral end pieces 521 of frame 506 . Computer 524 includes memory (eg, random access memory or volatile storage devices such as registers), storage devices (eg, non-volatile storage devices), wireless communication circuitry (eg, BLE communication devices) and/or WiFi direct devices), and one or more processors along with a power source. Computer 524 includes low-power circuitry, high-speed circuitry, and, in some embodiments, a display processor. Various embodiments may include these elements in different configurations or integrated together in different ways.

Computer 524 additionally includes a battery 527 or other suitable portable power source. In one embodiment, battery 527 is disposed in one of temples 509 . In the eyewear device 119 shown in FIG. 5 , a battery 527 is disposed in one of the end pieces 521 and is electrically connected to the rest of the computer 524 housed in the corresponding end piece 521 . are shown as connected.

The eyewear device 119 is camera-enabled, in this example a forward-facing camera mounted at one of the end pieces 521 and approximately aligned with the direction of the wearer's view of the eyewear device 119 ( 530). Camera 530 is configured to capture digital images (also referred to herein as digital photos or pictures) as well as digital video content. The operations of camera 530 are controlled by a camera controller provided by computer 524, and image data representative of images or video captured by camera 530 is stored in memory forming part of computer 524. temporarily stored on In some embodiments, eyewear device 119 may have a pair of cameras 530 , for example housed by respective end pieces 521 .

As described in more detail below, the onboard computer 524 and the lenses 512 bring the virtual content into the view of the lenses 512 by moving the virtual content from a first virtual position to a second virtual position. are configured together to provide a content centering system 107 that automatically and selectively re-centers virtual content to retrieve it. Specifically, the lenses 512 may display virtual content or one or more virtual objects. This makes the virtual content appear to the user as being integrated within the real-world environment the user sees through lenses 512 . In some embodiments, virtual content is received from client device 102 . In some embodiments, virtual content is received directly from application servers 114 .

The eyewear device 119 includes an accelerometer and touch interface and a voice command system. Based on input received by eyewear device 119 from the accelerometer and touch interface and voice command system, eyewear device 119 may control user interaction with the virtual content. In one example, user interaction may control playback of content presented on lenses 512 . In another example, user interaction may navigate a playlist or music or video library. In another example, user interaction involves scrolling through various three-dimensional or two-dimensional conversation elements (eg, chat bubbles) and selecting an individual conversation element to respond to generate messages to send to participants in the conversation. As such, users can navigate conversations in which they are engaged.

Content centering system 107 (which may be implemented by computer 524) assigns virtual content to virtual locations. The content centering system 107 monitors the current virtual location within the view of the real-world environment. The content centering system 107 retrieves virtual content for display within a specified range of the current virtual location in view. As the eyewear device 119 is moved around to be directed to a new portion of the real-world environment associated with the different set of virtual locations, the content centering system 107 may perform any virtual that is not within range of the different set of virtual locations. Exclude content. For example, as the eyewear device 119 is moved around to be directed to a new portion of the real-world environment that does not overlap with a previously displayed portion of the real-world environment, the content centering system 107 may cause different virtual Exclude any virtual content that is not within the range of the set of locations.

The content centering system 107 may receive a request to bring virtual content into a current view. In response, the content centering system 107 updates the virtual location assigned to and associated with the virtual content to be the virtual location associated with the current view of the real-world environment. As a result, the virtual content is now moved out of view to be included in the current view, allowing the user to interact with the virtual content. In some cases, the user may only interact with virtual content within the view of lenses 512 . If the user moves around to face a different direction, causing the virtual content to move out of view, user input no longer controls or interacts with the previously displayed virtual content until the virtual content is brought back into view. can't work

The eyewear device 119 further includes one or more communication devices, such as a Bluetooth low energy (BLE) communication interface. This BLE communication interface enables eyewear device 119 to communicate wirelessly with client device 102 . Other forms of wireless communication may also be used in place of or in addition to a BLE communication interface, such as a WiFi direct interface. The BLE communication interface implements a standard number of BLE communication protocols.

A first of the communication protocols implemented by the BLE interface of eyewear device 119 enables an unencrypted link to be established between eyewear device 119 and client device 102 . In this first protocol, the link-layer communication (physical interface or medium) between eyewear device 119 and client device 102 includes unencrypted data. In this first protocol, the application layer (the communication layer operating on physically exchanged data) encrypts and decrypts physically exchanged data in unencrypted form over the link layer of the BLE communication interface. In this way, data exchanged through the physical layer can be freely read by the eavesdropping device, but the eavesdropping device will not be able to decrypt the exchanged data without performing a decryption operation at the application layer.

A second of the communication protocols implemented by the BLE interface of eyewear device 119 enables an encrypted link to be established between eyewear device 119 and client device 102 . In this second protocol, the link-layer communication (physical interface) between the eyewear device 119 and the client device 102 receives data from the application layer and first converts the data before exchanging the data over the physical medium. Add type encryption. In this second protocol, the application layer (the communication layer that operates on physically exchanged data) uses a first type of encryption, over the link layer of the BLE communication interface, to physically exchange data in encrypted form. The second type of encryption may or may not be used to encrypt and decrypt . That is, data may be first encrypted by the application layer and then further encrypted by the physical layer before being exchanged over the physical medium. Following the exchange over the physical medium, the data is then decrypted by the physical layer and then decrypted again (eg, using a different type of encryption) by the application layer. In this way, data exchanged through the physical layer cannot be read by eavesdropping devices as the data is encrypted in the physical medium.

In some embodiments, client device 102 uses a first protocol to exchange images or videos or virtual content between messaging client 104 and eyewear device 119. communicate with

Content centering system

6 is a flow diagram illustrating example operations of content centering system 107 in performing process 600, according to an example embodiment. Process 600 may be implemented as computer-readable instructions for execution by one or more processors, such that the operations of process 600 may be performed in part or wholly by functional components of notification management system 107. can; Accordingly, process 600 is described below by way of example with reference thereto. However, in other embodiments, at least some of the operations of process 600 may be deployed on a variety of other hardware configurations. Accordingly, process 600 is not intended to be limited to content centering system 107 and may be implemented in whole or in part by any other component. Some or all of the actions of process 600 may be in parallel, out of sequence, or may be omitted entirely.

At operation 601, the content centering system 107 displays one or more virtual objects at a first virtual coordinate associated with the first portion of the real-world environment while the eyewear device is directed towards the first portion of the real-world environment. . For example, content centering system 107 may display thumbnails representing different media assets in lenses 512 of eyewear device 119 while eyewear device 119 is pointing towards a first room in the environment. display the list

At operation 602, the content centering system 107 determines that the eyewear device has been moved to be directed towards a second portion of the real-world environment. For example, content centering system 107 determines, based on GPS and/or accelerometer information, that lenses 512 are now pointing towards a second room in the environment.

At operation 603, the content centering system 107 maintains the display of one or more virtual objects at the first virtual coordinate while the eyewear device is directed towards the second portion of the real-world environment. For example, the content centering system 107 may prevent the list of thumbnails from being presented when the lenses 512 are pointing at a portion of the real-world environment that does not include or is associated with the first virtual location. To maintain a list of thumbnails associated with the first virtual coordinates.

At operation 604, the content centering system 107 receives a request to bring one or more virtual objects into the current view of the eyewear device. For example, the content centering system 107 may perform a physical gesture using a user's body part (eg, the user's hands) or a user tapping or long-pressing the touch input interface of the eyewear device. As such, a specific request may be received from the user. Content centering system 107 may also or alternatively receive a specific request from an application associated with virtual objects, indicating that an update associated with virtual objects is received.

At operation 605, the content centering system 107, in response to receiving this request, moves one or more virtual objects from a first virtual coordinate to a second virtual coordinate associated with a second portion of the real-world environment. For example, the content centering system 107 updates the virtual location assigned to and associated with the virtual content to be the virtual location associated with the current view of the real-world environment. As a result, the virtual content is now moved out of view to be included in the current view, allowing the user to interact with the virtual content.

7-10 are example screens of a graphical user interface of content centering system 107 according to example embodiments. The screens shown in FIGS. 7-10 may be provided by the messaging client 104 of the one or more client devices 102 , other applications implemented on the one or more client devices 102 , or the eyewear device 119 . can

For example, screen 700 shows a view of a first portion of real-world environment 701 through lenses 512 of eyewear device 112 . Eyewear device 112 may receive input from a user requesting to view a list of thumbnails representing a music or video library. In response, eyewear device 112 obtains one or more virtual objects 702 from client device 102 and/or from application servers 114 . Virtual objects 702 include thumbnails (eg, covers) representing different media assets (eg, different songs or videos). Eyewear device 112 associates virtual objects 702 with a first virtual location associated with a first portion of real-world environment 701 . Eyewear device 112 displays virtual objects 702 as three-dimensional objects at the center of lenses 512 . This makes it appear to the user viewing the first portion of the real-world environment 701 through the lenses 512 as if the virtual objects 702 were within the first portion of the real-world environment 701 .

Eyewear device 112 can receive input from the user (eg, verbally or via touch input or from client device 102 ) to interact with virtual objects 702 . For example, a user can scroll through virtual object 702 . Virtual objects lower in the list may appear farther away from the user than virtual objects earlier in the list. As the user scrolls through the virtual objects 702, the later virtual objects in the list are enlarged and brought into view closer to the user. A user may provide input to select a given one of the virtual objects 702 . In response, media assets associated with the selected virtual object are retrieved and presented to the user. Users can pause and fast-forward and rewind the playback of media assets.

In some cases, the user moves around while wearing the eyewear device 112 . For example, the user may turn their head to face the other direction, resulting in a second portion of the real-world environment being seen through the lenses 512 of the eyewear device 112 . As the user turns their head, the virtual objects 702 remain statically placed in the first virtual location. As a result, virtual objects 702 begin to move out of view and are removed from lenses 512 as the user turns their head. As shown in FIG. 8 , screen 800 shows a view of a second portion of the real-world environment that comes into view when the user turns his or her head to the left. Some of the virtual objects 702 on the far right that were previously visible through the lenses 512 are removed as the user turns to the left. For example, as shown in FIG. 8 , only a sub-portion of the virtual objects 702 remains visible when the user faces and looks at the second portion of the real-world environment.

Eyewear device 112 can receive a request to bring virtual objects 702 into the current view of lenses 512 . For example, the content centering system 107 may perform a physical gesture using a user's body part (eg, the user's hands) or a user tapping or long-pressing the touch input interface of the eyewear device. As such, a specific request may be received from the user. In response, as shown in screen 900 of FIG. 9 , virtual objects 901 are now associated with a virtual location within the view of lenses 512 (the virtual location of the second part of the environment). As a result, virtual objects 901 are now displayed while eyewear device 112 is facing the second portion of the real-world environment.

Eyewear device 112 can receive a request to bring virtual objects 702 into the current view of lenses 512 . For example, the content centering system 107 may receive a specific request from an application associated with virtual objects to indicate a pending update associated with virtual objects. For example, an update may be received when playback of a particular media asset ends, starts, stops, or pauses. As another example, an update may be received when a new message is received in a conversation in which the user is wearing the eyewear device 112 . In response, as shown in screen 1000 of FIG. 10 , virtual objects 1001 are now associated with a virtual location within the view of lenses 512 (the virtual location of the second part of the environment). As a result, virtual objects 1001 are now displayed while eyewear device 112 is facing the second portion of the real-world environment. The virtual objects 1001 include an indicator 1002 representing an update that caused the virtual objects 1001 to automatically enter the current view. For example, an indicator may include a border placed around a virtual object associated with an update (eg, a particular media asset whose playback has ended, started, stopped, or paused). As another example, the indicator may include a border or visual identifier of a chat bubble representing a message newly received in the conversation.

Accordingly, the phrase “hardware module” should be understood to encompass any tangible entity that is physically capable of acting in a particular way or performing particular operations described herein. configured, or permanently configured (eg, hardwired), or temporarily configured (eg, programmed). As used herein, “hardware-implemented module” refers to a hardware module. Considering embodiments in which hardware modules are temporarily configured (eg, programmed), each of the hardware modules need not be configured or instantiated at any one time. For example, if a hardware module includes a general-purpose processor that is configured by software to be a special-purpose processor, the general-purpose processor can be configured as different special-purpose processors at different times (eg, including different hardware modules). can be configured. Thus, software may, for example, configure a particular processor or processors to configure a particular hardware module at one point in time and a different hardware module at a different point in time.

Hardware modules can provide information to and receive information from other hardware modules. Accordingly, the described hardware modules may be considered as being communicatively coupled. Where multiple hardware modules coexist, communication may be achieved through signal transmission between or between two or more of the hardware modules (eg, via appropriate circuits and buses). In embodiments in which multiple hardware modules are configured or instantiated at different times, communication between or among such hardware modules may be, for example, storage of information in memory structures accessed by the multiple hardware modules. and through search. For example, one hardware module performs an operation and stores the output of that operation in a communicatively connected memory device. Additional hardware modules can then, at a later time, access the memory device to retrieve and process the stored output. Hardware modules can also initiate communication with input or output devices, and can operate on a resource (eg, a collection of information).

Various operations of example methods described herein may be performed at least in part by one or more processors that are either permanently configured or temporarily configured (eg, by software) to perform the related operations. Whether temporarily or permanently configured, these processors constitute processor-implemented modules that operate to perform one or more operations or functions described herein. As used herein, “processor-implemented module” refers to a hardware module implemented using one or more processors.

Similarly, the methods described herein may be at least partially processor-implemented, and a particular processor or processors are examples of hardware. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented modules. Moreover, the one or more processors may also operate to support performance of related operations in a “cloud computing” environment or as “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as an example of a machine including processors), and these operations may be performed over a network (eg, the Internet) and over one or more suitable interfaces (eg, the Internet). For example, it is accessible through an API).

Performance of certain operations may be distributed among processors, not only residing within a single machine, but also spread across multiple machines. In some demonstrative embodiments, processors or processor-implemented modules are located in a single geographic location (eg, within a home environment, office environment, or server farm). In other example embodiments, processors or processor-implemented modules are distributed across multiple geographic locations.
