AR graphical assistance for tasks

Abstract

Systems, methods, and computer-readable media for graphically assisting tasks using augmented reality (AR) wearable devices are disclosed. Embodiments capture an image of a first user view of a real-world scene and access an indication of a surface and a position of the surface detected in the image. The AR wearable device displays an indication of the surface on a display of the AR wearable device, wherein the location of the indication is based on the second user view of the real-world scene and the location of the surface. The position of the surface is indicated with 3D world coordinates. The user view is determined based on the location of the user. The AR wearable device enables a user to add graphics to a surface and select a task to perform. A tool, such as a bubble level or a measurement tool, may be used by a user to perform a task.

[0002] This application claims the benefit of U.S. patent application serial number 17 / 947,889, filed on September 19, 2022, the entire contents of which are incorporated herein by reference. Technical Field

[0003] Examples of the present disclosure generally relate to task-assisting a user using AR graphics on an augmented reality (AR) wearable device. More particularly, but not by way of limitation, examples of the present disclosure relate to capturing an image of a scene, processing the image to identify surfaces within the scene, and task-assisting the user by enabling the user to add an AR user graphic to the surface and providing tools to manipulate the AR user graphic. Background Art

[0004] Users increasingly expect virtual reality (VR), mixed reality (MR), and augmented reality (AR) wearable devices to operate in a more user-friendly manner with more functionality. However, typically, wearable devices have very little space for interface controls on the wearable device, and typically, AR wearable devices have limited power to provide additional functionality.

[0022] The following description includes systems, methods, techniques, instruction sequences and computer program products that embody illustrative examples of the present disclosure. In the following description, for the purpose of illustration, many specific details are set forth to provide an understanding of various examples of the subject matter of the present invention. However, it will be apparent to those skilled in the art that the examples of the subject matter of the present invention can be practiced without these specific details. Typically, known instruction instances, protocols, structures and techniques are not necessarily shown in detail.

[0023] The term AR wearable device is used as an illustrative device; however, one skilled in the art will recognize that the methods, systems, and computer-readable media disclosed herein are applicable to other wearable devices including VR wearable devices and MR wearable devices.

[0024] Such as Fig.12 AR glasses 1200 and the like shown in Figure 6 The AR wearable device 602 has limited physical user interface items. For example, the AR glasses 1200 have one or two buttons 1278 and a touchpad 1276 on the frame 1232 of the AR glasses 1200 that the user 644 interacts with. In addition, the AR glasses 1200 are limited by battery power.

[0025] Typically, user 644 wants to complete task 623, such as hanging a real-world painting, while wearing AR glasses 1200. Task 623 may be frustrating because user 644 may have to use a measuring device, a level, and a pencil to hang the painting. In addition, user 644 typically needs both of their hands to perform task 623, so use of client device 102 may be inconvenient.

[0026] One challenge is how to assist the user in performing tasks. This challenge is addressed by identifying a surface 632 within the user's view 672 of the real world scene 670 and identifying the surface 632 to the user 644 using AR graphics 686 such as overlays. The user 644 can then select a task 623 and can interact with the surface 632. The AR glasses 1200 provide hands-free operation so that the user 644 can perform tasks 623 that require two hands to perform.

[0027] Additional challenges include how to reduce the latency of providing graphical assistance to the user 644, and how to reduce energy consumption. According to some embodiments, these challenges are solved by sending the image 616 to the back end 618 to perform processing to determine the surface 632. In addition, other auxiliary functions are performed on the AR wearable device 602, such as placing holes for hanging paintings. In this way, some of the high-energy processing can be performed by the back end 618, and other low-energy processing can be performed by the AR wearable device 602. In addition, the latency of interacting with the user 644 can be reduced. These challenges are also solved by the AR wearable device 602 receiving the position 656 of the surface 632 in the 3D world coordinate system from the back end 618. When the user 644 moves, the AR wearable device 602 uses the position 656 and the new user view 672 to update the AR graphics 686. In addition, unless the user view 672 includes a new surface 632, the AR wearable device 602 avoids sending the additional image 616 to the back end 618 for processing. In some implementations, some or all of the image 616 processing is performed on the AR wearable device 602 .

[0028] Networked computing environment

[0029] Figure 1 1 is a block diagram illustrating an example messaging system 100 for exchanging data (e.g., messages and associated content) over a network. The messaging system 100 includes multiple instances of client devices 102, each of which hosts several applications including a messaging client 104 and other applications 106. Each messaging client 104 is communicatively coupled to other instances of the messaging client 104 (e.g., hosted on respective other client devices 102), a messaging server system 108, and a third-party server 110 via a network 112 (e.g., the Internet). The messaging client 104 may also communicate with the locally hosted application 106 using an application program interface (API).

[0030] The messaging clients 104 are able to communicate and exchange data with other messaging clients 104 and messaging server systems 108 via the network 112. The data exchanged between the messaging clients 104 and between the messaging clients 104 and messaging server systems 108 include functions (e.g., commands for activating functions) and payload data (e.g., text, audio, video, or other multimedia data).

[0031] The messaging server system 108 provides server-side functionality to specific messaging clients 104 via the network 112. Although certain functions of the messaging system 100 are described herein as being performed by the messaging client 104 or by the messaging server system 108, it may be a design choice for the certain functions to be located in the messaging client 104 or in the messaging server system 108. For example, it may be technically preferred to initially deploy certain technologies and functions within the messaging server system 108, but to later migrate the technologies and functions to the messaging client 104 where the client device 102 has sufficient processing power.

[0032] The messaging server system 108 supports various services and operations provided to the messaging clients 104. Such operations include sending data to the messaging clients 104, receiving data from the messaging clients 104, and processing data generated by the messaging clients 104. As examples, the data may include message content, client device information, geo-location information, media enhancements and overlays, message content permanence conditions, social networking information, and live event information. Data exchanges within the messaging system 100 are activated and controlled by functions available via the user interface (UI) of the messaging clients 104.

[0033] Turning now specifically to the messaging server system 108, an application program interface (API) server 116 is coupled to the application server 114 and provides a programming interface to the application server 114. The application server 114 is communicatively coupled to a database server 120, which facilitates access to a database 126 that stores data associated with messages processed by the application server 114. Similarly, a web server 128 is coupled to the application server 114 and provides a web-based interface to the application server 114. To this end, the web server 128 handles incoming network requests via the Hypertext Transfer Protocol (HTTP) and several other related protocols.

[0034] The application program interface (API) server 116 receives and sends message data (e.g., commands and message payloads) between the client device 102 and the application server 114. Specifically, the application program interface (API) server 116 provides a collection of interfaces (e.g., routines and protocols) that can be called or queried by the messaging client 104 to activate the functions of the application server 114. An application program interface (API) server 116 exposes various functions supported by the application server 114, including: account registration, login functionality, sending messages from a particular messaging client 104 to another messaging client 104 via the application server 114, sending media files (e.g., images or videos) from a messaging client 104 to a messaging server 118, and possible access by another messaging client 104, setting of collections (e.g., stories) of media data, retrieval of a friend list of a user of a client device 102, retrieval of such collections, retrieval of messages and content, addition and removal of entities (e.g., friends) of an entity graph (e.g., a social graph), position of friends within a social graph, and opening of application events (e.g., related to a messaging client 104).

[0035] The application server 114 hosts several server applications and subsystems, including, for example, a messaging server 118, an image processing server 122, and an input modality server 124. The messaging server 118 implements several message processing techniques and functions, particularly those related to the aggregation and other processing of content (e.g., text and multimedia content) included in messages received from multiple instances of the messaging client 104. As will be described in more detail, text and media content from multiple sources can be aggregated into collections of content (e.g., referred to as stories or galleries). These collections are then made available to the messaging client 104. In view of the hardware requirements of other processor and memory intensive data processing, the processing can also be performed on the server side by the messaging server 118.

[0036] The application servers 114 also include an image processing server 122 dedicated to performing various image processing operations, typically on images or videos within the payload of messages sent from or received at the messaging server 118 .

[0037] The input modality server 124 supports input modalities for AR wearable devices. The input modality server 124 receives requests from the AR wearable device and responds to the requests. The request includes sensor data such as images that are sent to the input modality server 124 for processing. The input modality server 124 processes the sensor data and identifies objects within the sensor data, and returns the names of the objects within the sensor data and the locations of the objects to the AR wearable device. Another request from the AR wearable device is for an AR application associated with a label such as a "QR code" that can be run on the AR wearable device. The input modality server 124 can load an AR application that may be used by a user of the AR wearable device to the AR wearable device, or can respond with an AR application based on criteria given from the AR wearable device to the input modality server 124. The criteria can be a limit on the number of AR applications, a user preference such as an AR application with a link back to the messaging system 100, and the like.

[0038] Returning to the messaging client 104, the features and functions of the external resource (e.g., application 106 or applet) are made available to the user via the interface of the messaging client 104. In this context, "external" refers to the fact that the application 106 or applet is outside the messaging client 104. External resources are usually provided by a third party, but can also be provided by the creator or provider of the messaging client 104. The messaging client 104 receives a user selection of an option for launching or accessing the features of such external resources. The external resource can be an application 106 (e.g., a "local app") installed on the client device 102, or a small-scale version of the application (e.g., a "applet") hosted on the client device 102 or away from the client device 102 (e.g., on a third-party server 110). The small-scale version of the application includes a subset of the features and functions of the application (e.g., a full-scale, local version of the application) and is implemented using a markup language document. In one example, the small-scale version of the application (e.g., a "applet") is a web-based markup language version of the application and is embedded in the messaging client 104. In addition to using markup language documents (eg, .*ml files), applets may include scripting languages ​​(eg, .*js files or .json files) and style sheets (eg, .*ss files).

[0039] In response to receiving a user selection of an option to launch or access a feature of an external resource, the messaging client 104 determines whether the selected external resource is a web-based external resource or a locally installed application 106. In some cases, an application 106 locally installed on the client device 102 can be launched independently of and separately from the messaging client 104, for example, by selecting an icon corresponding to the application 106 on a home screen of the client device 102. Small-scale versions of such applications can be launched or accessed via the messaging client 104, and in some examples, portions of the small-scale application cannot be accessed outside of the messaging client 104, or limited portions of the small-scale application can be accessed outside of the messaging client 104. The small-scale application can be launched by the messaging client 104 receiving, for example, a markup language document associated with the small-scale application from a third-party server 110 and processing the document.

[0040] In response to determining that the external resource is a locally installed application 106, the messaging client 104 instructs the client device 102 to launch the external resource by executing the locally stored code corresponding to the external resource. In response to determining that the external resource is a web-based resource, the messaging client 104 communicates with (for example) a third-party server 110 to obtain a markup language document corresponding to the selected external resource. The messaging client 104 then processes the obtained markup language document to present the web-based external resource within the user interface of the messaging client 104.

[0041] The messaging client 104 may notify the user of the client device 102 or other users (e.g., "friends") associated with the user of the client device 102 of activities occurring in one or more external resources. For example, the messaging client 104 may provide a participant in a conversation (e.g., a chat session) in the messaging client 104 with a notification related to the current or recent use of an external resource by one or more members of a user group. One or more users may be invited to join an active external resource or to launch an external resource that was recently used but is currently inactive (in a friend group). The external resource may provide the participants in the conversation who each use the corresponding messaging client 104 with the ability to share items, conditions, states, or locations in the external resource with one or more members of the user group entering the chat session. The shared items may be interactive chat cards that members of the chat may interact with to, for example, launch a corresponding external resource, view specific information within an external resource, or bring members of the chat to a specific location or state within an external resource. Within a given external resource, a response message may be sent to the user on the messaging client 104. The external resource may selectively include different media items in the response based on the current context of the external resource.

[0042] The messaging client 104 may present a list of available external resources (e.g., applications 106 or applets) to the user to launch or access a given external resource. The list may be presented in a context-sensitive menu. For example, icons representing different applications (or applets) of the applications 106 (or applets) may vary based on how the user launches the menu (e.g., from a conversational interface or from a non-conversational interface).

[0043] System Architecture

[0044] Figure 2 1 is a block diagram showing additional details about the messaging system 100 according to some examples. Specifically, the messaging system 100 is shown as including a messaging client 104 and an application server 114. The messaging system 100 contains several subsystems that are supported on the client side by the messaging client 104 and on the server side by the application server 114. These subsystems include, for example, a transient timer system 202, a collection management system 204, an enhancement system 208, a mapping system 210, a gaming system 212, an external resource system 214, and an image processing system 216.

[0045] The transient timer system 202 is responsible for implementing temporary or time-limited access to content by the messaging client 104 and the messaging server 118. The transient timer system 202 includes several timers that selectively enable access to messages and associated content (e.g., for presentation and display) via the messaging client 104 based on duration and display parameters associated with a message or a collection of messages (e.g., a story). Additional details regarding the operation of the transient timer system 202 are provided below.

[0046] The collection management system 204 is responsible for managing collections or collections of media (e.g., collections of text, images, video, and audio data). Collections of content (e.g., messages, including images, videos, text, and audio) can be organized into "event galleries" or "event stories." The collection can be made available for a specified time period, such as the duration of an event related to the content. For example, content related to a concert can be made available as a "story" for the duration of the concert. The collection management system 204 can also be responsible for publishing an icon to the user interface of the messaging client 104 that provides notification of the existence of a particular collection.

[0047] The collection management system 204 also includes a curation interface 206 that allows collection managers to manage and curate specific content collections. For example, the curation interface 206 enables an event organizer to curate a collection of content related to a specific event (e.g., to delete inappropriate content or redundant messages). Additionally, the collection management system 204 uses machine vision (or image recognition technology) and content rules to automatically curate content collections. In some examples, compensation can be paid to users for including user-generated content in a collection. In such cases, the collection management system 204 operates to automatically pay such users for using their content.

[0048] The enhancement system 208 provides various functions that enable users to enhance (e.g., annotate or otherwise modify or edit) media content associated with a message. For example, the enhancement system 208 provides functions related to the generation and publication of media overlays for messages processed by the messaging system 100. The enhancement system 208 is operable to provide media overlays or enhancements (e.g., image filters) to the messaging client 104 based on the geographic location of the client device 102. In another example, the enhancement system 208 is operable to provide media overlays to the messaging client 104 based on other information such as social network information of the user of the client device 102. Media overlays can include audio and visual content and visual effects. Examples of audio and visual content include pictures, text, logos, animations, and sound effects. Examples of visual effects include color overlays. Audio and visual content or visual effects can be applied to media content items (e.g., photos, digital objects) at the client device 102. For example, media overlays can include text or images that can be superimposed on photos taken by the client device 102. In another example, the media overlay includes a location identification overlay (e.g., Venice Beach), the name of a live event, or a business name overlay (e.g., Beach Cafe). In another example, the augmentation system 208 uses the geographic location of the client device 102 to identify a media overlay that includes the name of a business at the geographic location of the client device 102. The media overlay may include other tags associated with the business. The media overlay may be stored in the database 126 and accessed by the database server 120.

[0049] In some examples, the enhancement system 208 provides a user-based publishing platform that enables a user to select a geographic location on a map and upload content associated with the selected geographic location. The user can also specify situations in which a particular media overlay should be provided to other users. The enhancement system 208 generates a media overlay that includes the uploaded content and associates the uploaded content with the selected geographic location.

[0050] In other examples, the enhancement system 208 provides a merchant-based publishing platform that enables merchants to select specific media overlays associated with geographic locations via a bidding process. For example, the enhancement system 208 causes the media overlays of the highest-bidding merchant to be associated with the corresponding geographic location for a predetermined amount of time.

[0051] The mapping system 210 provides various geolocation functions and supports the presentation of map-based media content and messages by the messaging client 104. For example, the mapping system 210 enables the display of user icons or avatars (e.g., stored in the profile data 316) on a map to indicate the current or past locations of the user's "friends" and media content (e.g., a collection of messages including photos and videos) generated by the friends in the context of the map. For example, on the map interface of the messaging client 104, messages posted by the user to the messaging system 100 from a particular geographic location can be displayed to the "friends" of the particular user in the context of the particular location on the map. The user can also share his or her location and status information with other users of the messaging system 100 (e.g., using appropriate status avatars) via the messaging client 104, where the location and status information is similarly displayed to selected users within the context of the mapping interface of the messaging client 104.

[0052] The gaming system 212 provides various gaming functions within the context of the messaging client 104. The messaging client 104 provides a gaming interface that provides a list of available games 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 also enables a particular user to invite other users to participate in the play of a particular game by sending such other users an invitation from the messaging client 104. The messaging client 104 also supports both voice and text messaging (e.g., chat) within the context of game play, provides game leaderboards, and supports the provision of in-game rewards (e.g., coins and power-ups).

[0053] The external resource system 214 provides an interface for the messaging client 104 to communicate with a remote server (e.g., a third-party server 110) to launch or access external resources (e.g., applications or applets). Each third-party server 110 hosts, for example, applications based on a markup language (e.g., HTML5) or a small-scale version of an application (e.g., a game, utility, payment, or shared travel application). The messaging client 104 can launch a web-based resource (e.g., an application) by accessing an HTML5 file from a third-party server 110 associated with a web-based resource. In some examples, the application hosted by the third-party server 110 is programmed in JavaScript using a software development kit (SDK) provided by the messaging server 118. The SDK includes an application programming interface (API) having functions that can be called or activated by a web-based application. In some examples, the messaging server 118 includes a JavaScript library that provides a given external 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.

[0054] To integrate the functionality of the SDK into a web-based resource, the SDK is downloaded by the third-party server 110 from the messaging server 118, or received by the third-party server 110 in other ways. Once the SDK is downloaded or received, the SDK is included as part of the application code of the web-based external resource. The code of the web-based resource can then call or activate certain functions of the SDK to integrate the features of the messaging client 104 into the web-based resource.

[0055] The SDK stored on the messaging server 118 effectively provides a bridge between external resources (e.g., applications 106 or applet) and the messaging client 104. This provides users 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. In order to bridge the communication between the external resources and the messaging client 104, in some examples, the SDK facilitates the communication between the third-party server 110 and the messaging client 104. In some examples, the WebViewJavaScriptBridge running on the client device 102 establishes two one-way communication channels between the external resources and the messaging client 104. Messages are sent asynchronously between the external resources and the messaging client 104 via these communication channels. Each SDK function activation is sent as a message and a callback. Each SDK function is implemented by constructing a unique callback identifier and sending a message with the callback identifier.

[0056] By using the SDK, not all information from the messaging client 104 is shared with the third-party server 110. The SDK limits which information is shared based on the needs of the external resource. In some examples, each third-party server 110 provides an HTML5 file corresponding to a web-based external resource to the messaging server 118. The messaging server 118 can add a visual representation (e.g., box art or other graphics) of the web-based external resource in the messaging client 104. Once the user selects the visual representation or instructs the messaging client 104 to access the features of the web-based external resource through the GUI of the messaging client 104, the messaging client 104 obtains the HTML5 file and instantiates the resources required to access the features of the web-based external resource.

[0057] The messaging client 104 presents a graphical user interface (e.g., a login page or title screen) for an external resource. During, before, or after presenting a login portion of a reading material such as a page or title screen, the messaging client 104 determines whether the launched external resource has been previously authorized to access the user data of the messaging client 104. In response to determining that the launched external resource has been previously authorized to access the user data of the messaging client 104, the messaging client 104 presents another graphical user interface of the external resource including the functions and features of the external resource. In response to determining that the launched external resource has not been previously authorized to access the user data of the messaging client 104, after a threshold time period (e.g., 3 seconds) of displaying the login page or title screen of the external resource, the messaging client 104 slides up a menu (e.g., animating the menu to emerge from the bottom of the screen to the middle or other portion of the screen) 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 the user selection of the accept option, the messaging client 104 adds the external resource to the list of authorized external resources and enables the external resource to access the user data from the messaging client 104. In some examples, the messaging client 104 authorizes the external resource to access the user data according to the OAuth 2 framework.

[0058] The messaging client 104 controls the type of user data shared with the external resource based on the type of external resource that is authorized. For example, an external resource that includes a complete application (e.g., application 106) is provided with access to a first type of user data (e.g., only a two-dimensional avatar of the user with or without different avatar characteristics). As another example, an external resource that includes a small-scale version of an application (e.g., a web-based version of the application) is provided with access to a second type of user data (e.g., payment information, a two-dimensional avatar of the user, a three-dimensional avatar of the user, and an avatar with various avatar characteristics). Avatar characteristics include different ways to customize the look and feel of an avatar (e.g., different poses, facial features, clothing, etc.).

[0059] The image processing system 216 supports the system 600 of the AR wearable device. The image processing system 216 receives requests from the AR wearable device 602 and responds to the requests. Figure 6 As depicted, the request includes a request to process an image, such as image 616, to generate data 662 including surface 632. The AR wearable device may request other services from image processing system 216.

[0060] Data Architecture

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

[0062] Database 126 includes message data stored in message table 302. For any particular message, the message data includes at least message sender data, message recipient (or receiver) data, and payload. Figure 4 Additional details regarding information that may be included in a message and included within the message data stored in message table 302 are described.

[0063] The entity table 306 stores entity data and is linked (e.g., used as a reference) to the entity graph 308 and profile data 316. The entities whose records are maintained within the entity table 306 may include individuals, corporate entities, organizations, objects, places, events, etc. Regardless of the entity type, any entity for which the messaging server system 108 stores data may be an identified entity. Each entity is provided with a unique identifier as well as an entity type identifier (not shown).

[0064] The entity graph 308 stores information about relationships and associations between entities. Such relationships may be social, professional (e.g., working in a common company or organization), interest-based, or activity-based, by way of example only.

[0065] The profile data 316 stores multiple types of profile data about a particular entity. Based on the privacy settings specified by the particular entity, the profile data 316 can be selectively used and presented to other users of the messaging system 100. In the case where the entity is a person, the profile data 316 includes, for example, a user name, phone number, address, settings (e.g., notification and privacy settings), and an avatar representation (or a collection of such avatar representations) selected by the user. The particular user can then selectively include one or more of these avatar representations in the content of messages transmitted via the messaging system 100 and on a map interface displayed to other users by the messaging client 104. The collection of avatar representations can include a "situation avatar" that presents a graphical representation of a situation or activity that the user can choose to transmit at a particular time.

[0066] Where the entity is a group, the group profile data 316 may similarly include one or more avatar representations associated with the group, in addition to the group name, members, and various settings (eg, notifications) of the relevant group.

[0067] Database 126 also stores enhancement data, such as overlays or filters, in enhancement table 310. The enhancement data is associated with and applied to videos (whose data is stored in video table 304) and images (whose data is stored in image table 312).

[0068] In one example, a filter is an overlay that is displayed as an overlay on an image or video during presentation to a recipient user. Filters can be of various types, including filters that a sending user selects from a collection of filters presented to a sending user by messaging client 104 when composing a message. Other types of filters include geolocation filters (also known as geofilters), which can be presented to a sending user based on a geographic location. For example, a geolocation filter specific to a neighboring or special location can be presented by messaging client 104 within a user interface based on geographic location information determined by a global positioning system (GPS) unit of client device 102.

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

[0070] Other augmented data that may be stored in the image table 312 include augmented reality content items (eg, corresponding to applied Lenses or augmented reality experiences). Augmented reality content items may be real-time special effects and sounds that may be added to an image or video.

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

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

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

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

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

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

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

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

[0079] The transformation system can capture an image or video stream on a client device (e.g., client device 102) and perform complex image manipulations locally on the client device 102 while maintaining an appropriate user experience, computation time, and power consumption. Complex image manipulations can 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), style transitions, application of graphical elements, and any other suitable image or video manipulations enabled by a convolutional neural network that has been configured to execute efficiently on the client device 102.

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

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

[0082] The story table 314 stores data about a collection of messages and associated images, video or audio data that are compiled into a collection (e.g., a story or gallery). The creation of a particular collection can be initiated by a particular user (e.g., each user whose record is maintained in the entity table 306). A user can create a "personal story" in the form of a collection of content that has been created and sent / broadcasted by the user. To this end, the user interface of the messaging client 104 may include a user-selectable icon to enable the sending user to add specific content to his or her personal story.

[0083] A collection may also constitute a "live story" that is a collection of content from multiple users, created manually, automatically, or using a combination of manual and automatic techniques. For example, a "live story" may constitute a curated stream of user-submitted content from different locations and events. Users whose client devices have location services enabled and who are at a common location event at a particular time may be presented with an option, for example via a user interface of the messaging client 104, to contribute content to a particular live story. Live stories 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.

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

[0085] As mentioned above, the video table 304 stores video data, which in one example is associated with a message whose record is maintained within the message table 302. Similarly, the image table 312 stores image data associated with a message for which message data is stored in the entity table 306. The entity table 306 may associate various enhancements from the enhancement table 310 with the various images and videos stored in the image table 312 and the video table 304.

[0086] Data communication architecture

[0087] Figure 4is a schematic diagram illustrating the structure of a message 400 according to some examples, the message 400 being generated by a messaging client 104 for transmission to another messaging client 104 or a messaging server 118. The content of a particular message 400 is used to populate a message table 302 stored in a database 126 accessible by a messaging server 118. Similarly, the content of the message 400 is stored in memory as "in-flight" or "in-flight" data of a client device 102 or application server 114. The message 400 is shown as including the following example components:

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

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

[0090] • Message Image Payload 406: Image data captured by a camera component of the client device 102 or obtained from a memory component of the client device 102 and included in the message 400. The image data for a message 400 sent or received may be stored in the image table 312.

[0091] • Message video payload 408: Video data captured by a camera component or obtained from a memory component of the client device 102 and included in the message 400. The video data for a message 400 sent or received may be stored in the video table 304.

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

[0093] Message enhancement data 412 : Enhancement data (eg, filters, stickers, or other annotations or enhancements) representing enhancements to be applied to the message image payload 406 , message video payload 408 , or message audio payload 410 of the message 400 .

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

[0095] Message geolocation parameters 416: Geolocation data (e.g., latitude and longitude coordinates) associated with the content payload of the message. Multiple message geolocation parameter 416 values ​​may be included in the payload, each of which is associated with a content item included in the content (e.g., a specific image within a message image payload 406 or a specific video in a message video payload 408).

[0096] Message story identifier 418: An identifier value that identifies one or more content collections (e.g., "Stories" identified in stories table 314) with which a particular content item in message image payload 406 of message 400 is associated. For example, multiple images within message image payload 406 may each be associated with multiple content collections using an identifier value.

[0097] Message tags 420: Each message 400 may be tagged with a plurality of tags, each of which indicates the subject of the content included in the message payload. For example, where a particular image included in the message image payload 406 depicts an animal (e.g., a lion), a tag value may be included within the message tags 420 indicating the relevant animal. The tag values ​​may be manually generated based on user input, or may be automatically generated using, for example, image recognition.

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

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

[0100] The content (e.g., value) of each component of message 400 may be a pointer to a location in a table in which the content data value is stored. For example, the image value in message image payload 406 may be a pointer to a location in image table 312 (or the address of a location in image table). Similarly, the value in message video payload 408 may point to data stored in video table 304, the value stored in message enhancement 412 may point to data stored in enhancement table 310, the value stored in message story identifier 418 may point to data stored in story table 314, and the values ​​stored in message sender identifier 422 and message recipient identifier 424 may point to user records stored in entity table 306.

[0101] Time-based access restriction architecture

[0102] Figure 5is a schematic diagram illustrating an access restriction process 500 in which access to content (e.g., an ephemeral message 502 and associated multimedia data payload) or a collection of content (e.g., an ephemeral message group 504) may be time-restricted (e.g., made ephemeral).

[0103] The ephemeral message 502 is shown to be associated with a message duration parameter 506, the value of which determines the amount of time that the messaging client 104 will display the ephemeral message 502 to the receiving user of the ephemeral message 502. In one example, the receiving user may view the ephemeral message 502 for up to a maximum of 10 seconds, depending on the amount of time specified by the sending user using the message duration parameter 506.

[0104] The message duration parameter 506 and the message recipient identifier 424 are shown as inputs to a message timer 510, which is responsible for determining the amount of time that the transient message 502 is shown to a particular receiving user identified by the message recipient identifier 424. In particular, the transient message 502 is shown to the associated receiving user only for the period of time determined by the value of the message duration parameter 506. The message timer 510 is shown as providing an output to a more generalized transient timer system 202, which is responsible for the overall timing of displaying content (e.g., the transient message 502) to the receiving user.

[0105] exist Figure 5 1. Ephemeral message 502 is shown as being included within an ephemeral message group 504 (e.g., a collection of messages in a personal story or event story). Ephemeral message group 504 has an associated group duration parameter 508, the value of which determines the duration for which ephemeral message group 504 is presented to and accessible by users of messaging system 100. For example, group duration parameter 508 may be the duration of a concert, wherein ephemeral message group 504 is a collection of content about the concert. Alternatively, a user (an owning user or a curator user) may specify the value of group duration parameter 508 when performing setup and creation of ephemeral message group 504.

[0106] In addition, each ephemeral message 502 within the ephemeral message group 504 has an associated group participation parameter 512, the value of which determines the duration for which the ephemeral message 502 is accessible within the context of the ephemeral message group 504. Thus, the ephemeral message group 504 may "expire" and become inaccessible within the context of the ephemeral message group 504 before the particular ephemeral message group 504 itself expires in accordance with the group duration parameter 508. The group duration parameter 508, the group participation parameter 512, and the message recipient identifier 424 each provide inputs to a group timer 514, which operatively first determines whether a particular ephemeral message 502 of the ephemeral message group 504 is to be displayed to a particular receiving user, and if so, how long to display it. Note that the identity of the particular receiving user is also known to the ephemeral message group 504 due to the message recipient identifier 424.

[0107] Thus, the group timer 514 operatively controls the overall lifespan of the associated ephemeral message group 504 and the individual ephemeral messages 502 included in the ephemeral message group 504. In one example, each ephemeral message 502 within the ephemeral message group 504 remains viewable and accessible for a period of time specified by the group duration parameter 508. In another example, within the context of the ephemeral message group 504, a particular ephemeral message 502 may expire based on the group participation parameter 512. Note that even within the context of the ephemeral message group 504, the message duration parameter 506 may still determine the duration for which a particular ephemeral message 502 is displayed to a receiving user. Thus, the message duration parameter 506 determines the duration for which a particular ephemeral message 502 is displayed to a receiving user, regardless of whether the receiving user is viewing the ephemeral message 502 within or outside the context of the ephemeral message group 504.

[0108] The transient timer system 202 may also be operable to remove a particular transient message 502 from a transient message group 504 based on a determination that an associated group participation parameter 512 has been exceeded. For example, when a sending user has established a group participation parameter 512 of 24 hours from posting, the transient timer system 202 will remove the associated transient message 502 from the transient message group 504 after the specified 24 hours. The transient timer system 202 also operates to remove a transient message group 504 when the group participation parameter 512 of each transient message 502 within the transient message group 504 has expired or when the transient message group 504 itself has expired according to the group duration parameter 508.

[0109] In some use cases, the creator of a particular ephemeral message group 504 may specify an infinite group duration parameter 508. In this case, the expiration of the group participation parameter 512 of the last remaining ephemeral message 502 within the ephemeral message group 504 will determine when the ephemeral message group 504 itself expires. In this case, a new ephemeral message 502 with a new group participation parameter 512 added to the ephemeral message group 504 effectively extends the life of the ephemeral message group 504 to a value equal to the group participation parameter 512.

[0110] In response to the transient timer system 202 determining that the ephemeral message group 504 has expired (e.g., is no longer accessible), the transient timer system 202 communicates with the messaging system 100 (and, for example, in particular, the messaging client 104) to cause the indicia (e.g., icon) associated with the relevant ephemeral message group 504 to no longer be displayed within the user interface of the messaging client 104. Similarly, when the transient timer system 202 determines that the message duration parameter 506 of a particular ephemeral message 502 has expired, the transient timer system 202 causes the messaging client 104 to no longer display the indicia (e.g., icon or text identification) associated with the ephemeral message 502.

[0111] Using AR wearable devices to graphically assist tasks

[0112] Figure 6 A system 600 for graphically assisting a task using an AR wearable device is shown according to some examples. The system 600 includes a Fig.12 The AR wearable device 602 may include other devices such as the glasses 1200, and may include a portion of the messaging server system 108 or the client device 102 that may perform one or more of the operations described herein.

[0113] Input / output (IO) devices 604 include devices that enable a user 644 to receive output or provide input to the system 600. IO devices 604 include microphone 606, display 610, speakers (not shown), image capture device 608, buttons 612, touchpad 613, gyroscope (not shown), etc. According to some embodiments, image capture device 608 captures an image 616 of a real world scene 670 as a front facing view of a user view 672, which is what the user 644 sees through the AR wearable device 602. Location (loc) 673 is a 3D coordinate within a 3D world coordinate system indicating the location of the user view 672. Image capture device 608 can be a charge coupled device (CCD) or another type of device for capturing an image of the real world scene 670. Fig.12612. The button 1278 is an example of a button 612. The touch pad 1276 is an example of a touch pad 613. The button 612 and the touch pad 613 enable the user 644 to provide tactile 646 input. The microphone 606 enables the user 644 to provide voice 650 input. The image capture device 608 enables the user 644 to provide gesture 648 input via the UI module 634, which processes or analyzes the image 616 to determine the user intent 636 based on the gesture 648.

[0114] Some devices, such as a gyroscope, can be both a sensor 614 and an IO device 604. For example, a user 644 can move an AR wearable device 602, which changes the location 652 of the user 644 and transmits input to the AR wearable device 602. According to some embodiments, it is assumed that the location of the user 644 is the same as the AR wearable device 602. According to some embodiments, the AR wearable device 602 detects a change in location 652 using a sensor 614, such as a gyroscope or another inertial sensor, to detect a change in location 652 of the user 644. In some embodiments, the AR wearable device 602 detects a change in location 652 by analyzing an image 616, which can be done in conjunction with a sensor 614, such as a gyroscope. For example, a simultaneous localization and mapping (SLAM) system can be implemented by the AR wearable device 602 and / or the backend 618. In other embodiments, the AR wearable device 602 detects motion by exchanging wireless communications with a wireless device via a wireless module 659. In some embodiments, a GPS system is used to detect motion of the AR wearable device 602. In addition, a combination of two or more of these methods may be used. The movement of user 644 may have user intent 636 to transmit input to AR wearable device 602. However, user 644 may move with AR wearable device 602 without user intent 636 to transmit input to AR wearable device 602.

[0115] Sensors 614 include gyroscopes, light sensors, positioning sensors, clocks, etc. Wireless module 659 transmits 654 between backend 618 and AR wearable device 602. Wireless module 659 is configured to perform wireless communication protocols with backend 618, such as LE Bluetooth, Institute of Electrical and Electronics Engineers (IEEE) 802.11 communication protocol, proprietary communication protocol, 3GPP communication protocol, etc. Wireless module 659 establishes a wireless communication link between AR wearable device 602 and backend 618. For example, wireless module 659 is associated with a corresponding wireless module on backend 618. Wireless module 659 can communicate with backend 618 via another intermediate device such as client device 102, which can also be backend 618, access point or node B. In some embodiments, wireless module 659 can be used to determine the position and / or orientation of AR wearable device 602 with the assistance of other wireless devices.

[0116] Assistance state 664 is stored in the memory of AR wearable device 602 and indicates the state of AR wearable device 602 for processing image 616 to assist task 623. Assistance state 664 is changed based on user 644 input. For example, user 644 can use button 612, touchpad 613, voice 650 input, or gesture 648 input to turn assistance state 664 "on" or "off".

[0117] If the auxiliary state 664 is in the "on" state, the image display module 624 causes the image 616 to be captured by the image capture device 608, and the image display module 624 uses the image 616 as the image 616 to be processed to identify the surface 632 within the image 616. In some embodiments, an existing image 616 can be used by the image display module 624. The image display module 624 can continuously capture images 616 and process the images 616 to identify the surface 632. In some embodiments, there are multiple image capture devices 608, and the image display module 624 selects one or more image capture devices 608 that look forward or overlay the real world scene 670 that the user 644 sees through, for example, the glasses 1200.

[0118] The image display module 624 is configured to cause the image 616 to be sent to the backend 618 for processing by the machine learning (ML) module 620. The backend 618 may be the messaging server system 108 or the client device 102. In some implementations, the ML module 620 resides in the AR wearable device 602. The functionality of the ML module 620 may be divided between the backend 618 and the AR wearable device 602. For example, the ML module 620 on the backend 618 may identify all surfaces 632, and the ML module on the AR wearable device 602 may identify objects within the image 616.

[0119] ML module 620 processes image 616 to generate data 662. Data 662 includes surface 632 and other information about surface 632. The other information includes label 660 and location 656. In some examples, ML module 620 is a neural network that is trained to identify surface 632 and label 660 surface 632. In some implementations, ML module 620 is trained to identify a collection of surfaces 632 that may be of interest to user 644 to perform task 623.

[0120] The tags 660 identify the surface 632 with tags such as "wall", "paper", "floor", "ceiling", "painting", "person", "sofa", "chair", etc. The surface 632 may be part of the object 661, such as "wall", "paper", "floor", "ceiling", "painting", "person", "sofa", "chair", "room", etc. The tags 660 may be different from the object 661. For example, where the object 661 is a "room", the surface 632 may have a tag 660 of "side wall". In another example, where the object 661 is a "chair", the surface 632 may have a tag 660 of "front of chair". The recognized surface 632 may be a finite number of surfaces 632 that the ML module 620 is trained to recognize, where the surface 632 is selected based on the surface 632 that the user 644 may want to recognize for one of the tasks 623. According to some embodiments, the positions 656, 682, 688 are positions within 3D world coordinates. In some implementations, one or more of the locations 656 , 682 , 688 may be represented relative to the location 652 or another location 656 , 682 , 688 of the user 644 or the AR wearable device 602 .

[0121] User graphics 680 are graphics that user 644 adds while using system 600. For example, user 644 may add user graphics 680 with label 684 of "hole" having location 682 on surface 632. In one example, the "hole" is a place holder where user 644 will hammer in a nail for a painting.

[0122] The term AR graphics includes any content displayed by the AR wearable device 602 on the display 610 for the user 644 to view in conjunction with viewing the real world through the lens. Alternatively, the user 644 can view the real world through the AR wearable device 602 that captures the image 616 and displays the image 616 and the AR graphics on the opaque display 610.

[0123] For example, the AR graphic 686 is a graphic generated by the image display module 624. In one example, the AR graphic 686 is a line between two user graphics 680 with a mark 684 of a "hole", where the mark 690 of the line indicates the distance between the two "holes". In another example, the AR graphic 686 includes information about the image 616 that can be inferred by the image display module 624 or determined by the ML module 620 and included in the data 662, such as it is possible that it is an indoor image. The AR graphic 686 includes an indication of the surface 632, which can be a mark or an overlay. The overlay is an indication of the surface 632 by, for example, coloring the surface or creating another mirrored surface that appears in front of the surface 632.

[0124] Tasks 623 are tasks that the user 644 wants to complete. For example, tasks 623 may include "hanging a painting", "measuring the distance between two points", "measuring the size of an object", "leveling an object", "determining the height of a wall", "determining the size of a paper", "determining the height of a person", etc. Each task 623 may include one or more steps 625. For example, the task 623 of "hanging a painting" includes "selecting the location of the nails", "driving the nails", and "hanging the painting", each of which may include one or more steps 625 for performing the task. Measurement units 627 is a state indicating the current unit of measurement to be used, such as inches, centimeters, feet, meters, etc.

[0125] The image display module 624 processes the surface 632, the user graphic 680, and the AR graphic 686 and displays them on the display 610 for the user 644 to view in conjunction with the user view 672 of the real world scene 670. According to some embodiments, the image display module 624 uses the surface 632 to display the AR graphic 686 as a marker 660 or overlay on the surface 632 to more clearly identify the surface 632 to the user 644. The adjustment module 626 projects or adjusts the user graphic 680 and the AR graphic 686 to be at an appropriate perspective for the location 673 of the user view 672. For example, the size and angle of the line are adjusted according to the location 656 of the surface within the user view 672 of the real world scene 670 to fit the surface 632.

[0126] In some embodiments, the motion sensor 614 is used to determine the movement 666 of the AR wearable device 602. Then, the change of the position 673 is determined based on the movement 666. According to some embodiments, the user graphics 680 and the AR graphics 686 can be moved by a number of pixels based on the movement 666 of the AR wearable device 602. Because the position 673 of the user view 672 and the positions 656, 682, 688 are 3D coordinates within the 3D world coordinate system, the image display module 624 can display the surface 632, the user graphics 680, and the AR graphics 686 based on the positions 656, 682, and 688 and the position 673. The new surface module 667 determines whether the image 616 needs to be analyzed for the new surface 632 based on the previous user view 672 and the position 673 compared to the current user view 672 and the position 673. In some embodiments, the new surface module 667 uses a threshold to determine whether to process the image 616 to determine the new data 662. For example, if the new position 673 indicates that less than 5% of the user's view 672 has changed since the old position 673, the new surface module 667 determines not to process the image 616 for the new data 662. According to some embodiments, not processing the image 616 may have little impact on the experience of the user 644, but may prevent delays and save energy. In some embodiments, the UI module 634 presents a user interface item that provides the user 644 with the option of processing the image 616 to obtain the new data 662.

[0127] The UI module 634 processes input from the IO device 604 to determine the user intention 636 from the user 644. The UI module 634 determines whether the user intention 636 turns the auxiliary state 664 to "on" or "off". The UI module 634 provides or displays user interface items, such as a menu for selecting options for the task 623. The UI module 634 enables the user 644 to add a user graphic 680 such as "hole". The user 644 can use a gesture 648 such as finger movement to select an area of ​​the image 616 to add the user graphic 680. The UI module 634 analyzes the movement of the finger by analyzing the image 616 captured over time. The UI module 634 can determine or estimate the gaze position of the user 644. The user intention 636 can be determined based on the input from the user 644 and the current task 623 and step 625.

[0128] In some embodiments, the image display module 624 maintains a data structure for storing the surface 632 and its location 656 so that if the user 644 moves and then returns, the surface 632 and location 656 are still accessible to the AR wearable device 602. For example, the user 644 can walk out of the room and then return to the room. According to some embodiments, the AR wearable device 602 uses the 3D coordinates within the 3D world coordinate system to keep track of its location 652, and determines the user view 672 based on the location 652. In some embodiments, because the user 644 is in the middle of a task 623 such as "hanging a painting", the new surface module 667 determines not to process the new image 616. For example, the user 644 can set up a "hole" to hang a painting that can be a picture, and then walk into another room. The new surface module 667 determines that the user 644 is no longer in the location of the task 623, so it stops processing the new image 616 for the data 662. The user 644 can cause the AR wearable device 602 to start processing the new image 616 for the data 662 by ending the task 623 , resetting the task 623 , or starting a new task 623 .

[0129] User 638 is data related to user 644. Information (info) 642 includes input data from user 644 and may include additional information about user 638, such as social media accounts logged into messaging server system 108, user names, and the like.

[0130] Figure 7 The operation of a system for graphically assisting a task according to some embodiments is shown. The user view 672 is what the user 644 sees when wearing the AR wearable device 602. The assistance state 664 is "on". The image display module 624 processes the image 616, and the image capture device 608 can be set to capture images 616 periodically so that the user 644 perceives the user graphics 680 and the AR graphics 686 in appropriate locations within the user view 672, and the user graphics 680 and the AR graphics 686 do not jump or distort. For example, the image display module 624 can capture 30 images 616 or other suitable numbers per second. In some embodiments, the image display module 624 adjusts the user graphics 680 and the AR graphics 686 based on changes in the position 63 of the user view 672.

[0131] The image display module 624 either sends the image 616 to the backend 618 or processes the image 616 on the AR wearable device 602. Data 662 including the surface 632 is created for the image 616.

[0132] The image display module 624 displays markings 660 of the surface 632 on the display 610, including "Wall 1" 708, "Wall 2" 706, "Ceiling" 704, "Wall 3" 712, and "Floor" 710. In some embodiments, the surface 632 is displayed using an overlay, such as a thin cube projected onto the surface and that can have different colors. The image display module 624 displays a UI item "feet" 718, which indicates that "feet" is the current measurement unit 627. The user 644 can select the UI item "feet" 718 to change the measurement unit 627. According to some embodiments, the image display module 624 determines some AR graphics 868 by determining some distances and heights based on the surface 632 and the location 656. The AR graphics 868 include "22 feet" 714, "15 feet" 720, and "8 feet" 716.

[0133] The image display module 624 displays a menu 722 on the display 610. The menu 722 indicates tasks 623 that the user 644 can select from. For example, the user 644 can indicate the selection of "Hanging Paintings" by performing a gesture 648 selecting "Hanging Paintings" with the finger 724 of the user 644. The UI module 634 determines that the user intent 636 is to select "Hanging Paintings" based on identifying the positioning of the finger 724 on the "Hanging Paintings" and the gesture 648. In other examples, the user 644 can select the task 623 from the menu 722 using the button 612, the touchpad 613, or the voice 650 input.

[0134] "+" is a sign 709, which is an indication that the UI module 634 has determined where the center of the focus of the user 644 is. The user 644 can select the position 682 of the user graphic 680 or select a UI item based on the positioning of the sign 709. For example, the user 644 can move the sign 709 to the task 623 "hanging painting", and then perform the selection of the task 623 "hanging painting". The selection can be a tactile 646, a gesture 648, a voice 650 command or another input. In some embodiments, the UI module 634 determines where the focus of the eyes of the user 644 is to determine the positioning of the sign 709. In some embodiments, the positioning of the sign is determined by centering the sign 709 in the user view 672. In some embodiments, the menu 722 is given a fixed position in the user view 672, which enables the user 644 to move, for example, their head to locate the sign 709 through the UI item. In some embodiments, the finger 724 of the user 644 is used to move the position 682 of the sign 709.

[0135] Figure 8 Operation of a system for graphical assistance with a task is shown in accordance with some implementations. Figure 86 shows a situation where user 644 has selected task 623 "Hang a painting" from menu 722. User 644 selects "Hole 1" 816 and "Hole 2" 818 where they intend to place nails to perform task 623 of "Hang a painting". The holes may be placed by user 644 by selecting the locations 682 of the user graphics 680 of the holes. "Hole 1" is labeled 684. User 644 selects "Hole 2" 818 where they intend to place nails to perform task 623 of "Hang a painting". Figure 7 Mark 709 is placed on position 682 and then position 682 is selected to select hole position 682.

[0136] Alternatively, the user 644 uses their finger 724 to select the location 682 of the hole. The task 623 of "hanging the painting" has a step 625 that includes one or more of the following: capturing an image of the front of the real painting, capturing an image of the back of the real painting, determining the location of "hole 1" 816, determining the location of "hole 2", "adjust hole", "hang AR painting", "cancel", etc. In some embodiments, the image display module 624 prompts the user 644 to perform one or more of the steps 625, such as capturing images of the front and back of the real painting. In some embodiments, during a step 625 such as capturing an image of the real painting, the image display module 624 will pause processing of the image 616 for the surface 632 to save battery life. For example, the user 644 can perform the step 625 of taking the image 616 of the real painting by walking into another room, so when the user 644 goes to take the image 616 of the real painting, the image display module 624 pauses processing of the image 616 for the surface 632 until the user 644 returns to the original room. The menu 820 has been relative to Figure 7 608 . The user view 672 within the real world scene 670 has changed as the user 644 has approached “Wall 1” 708. The image display module 624 displays “12 feet” 822 instead of “15 feet” 720 because the user 644 has stepped within 15 feet of “Wall 1” 708. The image display module 624 uses the positions 682 , 656 , and 688 , respectively, within the 3D world coordinate system to adjust the user graphic 680 , the surface 632 , and the AR graphic 686 based on the changed position 673 of the user 644 .

[0137] Fig. 9Operation of a system for graphical assistance with a task is shown in accordance with some implementations. Fig. 9 Shown after selecting the "Hang AR Painting" UI item of menu 820 Figure 8 . The image display module 624 displays the AR painting 906. The image display module 624 adjusts the size of the AR painting 906 according to the position 673 of the user view 672 relative to the location on “Wall 1” 708 where the “AR painting” 906 is displayed. The size of the AR painting 906 can be adjusted, and the size of the AR painting 906 can be determined by capturing an image 616 of the real painting. The user view 672 within the real-world scene 670 has changed when the user 644 has approached “Wall 1” 708. The image display module 624 displays “11 feet” 908 instead of “12 feet” 822 because the user 644 has stepped within 11 feet of “Wall 1” 708. The image display module 624 displays “3 feet” 904, “3 feet” 902, “3 feet” 810, and “3 feet” 812. The user 644 can adjust the “AR painting” 906 by selecting the UI item “Golden Ratio” in the menu 920. After the user 644 selects the "Golden Ratio" from the menu 920, the image display module 624 adjusts the position 688 of the "AR painting" so that the height of the "AR painting" to the floor divided by the distance from the top of the "AR painting" to the "ceiling" 704 is the "Golden Ratio". The image display module 624 can perform other adjustments to the position 688 of the "AR painting" 906 according to the "Golden Ratio", such as from left to right. The positioning of the AR painting 906 can also be determined based on the positioning of the hook on the back of the actual painting.

[0138] If user 644 selects the user interface item "Hang Painting" from menu 920, AR painting 906 will be removed and "Hole 1" 816 and "Hole 2" 818 will be visible. "Hole 1" 816 and "Hole 2" 818 may be adjusted or leveled based on the selection of bubble gauge 804, the initial option to place the holes on a horizontal line, the selection of the "golden ratio", user 644 moving AR painting 906, or another reason. User 644 then places nails in "Hole 1" 816 and "Hole 2" 818 and hangs the real painting, which should look the same or similar to AR painting 906.

[0139] Fig.10 The operation of a system for graphically assisting with a task in accordance with some embodiments is shown. Fig.10, user 644 is in the middle of task 623 of determining the distance between two points. User 644 has selected "point 1" 904, and the second point is currently "marker" 1018. The distance between "point 1" 904 and "marker" 1018 is "4 feet" 1020. User 644 can continue to move "marker" 1018 around the room. App carousel 100 is displayed with options for user 644 to select from. Options include: "Set" 1002, which sets "marker" 1018 at its current location; "Align" 1004, which moves "marker" 1018 to align "marker" 1018 according to some symmetry with "point 1" 1016; advance 1006, which will switch step 625 of current task 623; cancel 1012, which cancels current task 623; and menu 1014, which displays a menu similar to menu 920.

[0140] Fig.11 A method 1100 for graphically assisting a task using an AR wearable device is shown according to some examples. The method 1100 may be performed by a user such as Fig.12 The operations may be performed by an AR wearable device 602 such as glasses 1200. One or more of the operations may be performed in whole or in part by other devices such as a client device 102 or a portion of a messaging server system 108.

[0141] The method 1100 begins at operation 1102 where a measurement mode activation is detected. For example, the user 644 selects the button 612 of the AR wearable device 602 and uses a gesture 648 or a voice 650 command to set the assist state 664 to “on”.

[0142] The method 1100 continues at operation 1104 by capturing an image. For example, the image display module 624 causes the image capture device 608 to capture the image 616.

[0143] The method 1100 continues at operation 1108 with finding a surface, which includes sending the image and instructions to detect the surface 1105 to the surface detection module 1106, which returns real-time information 1112 about the detected surface, which is an example of data 662. For example, the image display module 624 sends the image 616 and instructions to find the surface 632 to the back end 618, where the ML module 620 finds the surface 632 and sends back data 662 with an indication of the surface 632. In some embodiments, the AR wearable device 602 can use the ML module 620 resident on the AR wearable device 602 to find the surface 632.

[0144] The method 1100 continues at operation 1110, showing the surface overlay. For example, as discussed herein, the image display module 624 displays the surface 632, the user graphic 680, and the AR graphic 686. In addition, the AR wearable device 602 may determine not to process additional images 616 after initially finding the surface 632 of one or more images 616 until the position 673 of the user view 672 changes by more than or across a threshold or less than or does not cross a threshold. For example, the threshold may be based on a change in the position 673 of the user view 672, such as a threshold of 5 degrees of rotation of the AR wearable device 602, where 5 degrees is determined based on a change in the position 673 of the user view 672. The user view 672 changes as the user 644 changes the position 673. The user view 672 may be referred to as a first user view 672, a second user view 672, a third user view 672, etc., to indicate that the position 673 changes as the user 644 moves.

[0145] The method 1100 continues at operation 1114 by receiving a selection of a task. For example, the AR wearable device 602 detects that the user 644 responds to a task from Figure 7 The method 1100 continues at operation 1116 by detecting a user interaction with the task. For example, Figures 7 to 10 User 644 is shown interacting with system 600 to perform task 623. Specifically, Figures 7 to 9 In FIG. 6 , the AR wearable device 602 detects a user interaction of selecting the task “hanging a painting” and in FIG. Fig.10 , the AR wearable device 602 detects a user 644 interaction selecting a task of determining “the distance between two points”.

[0146] Method 1100 continues at operation 1118 by displaying AR results from the detected user interaction. Figure 8 , “Hole 1” 816 and “Hole 2” 818 are displayed on the display 610 of the AR wearable device 602 and remain displayed as the user 644 hammers the nails into the locations where “Hole 1” 816 and “Hole 2” 818 are located.

[0147] The method 1100 may include one or more additional operations. The operations of the method 1100 may be performed in a different order. One or more of the operations of the method 1100 may be optional. The method 1100 may be performed by the client device 102, the system 600, the glasses 1200, or another electronic device. Portions of the functions may be performed on a server computer or host. For example, the glasses 1200 may be coupled to a host client device 102 or an application server 114, and one or more of the operations may be performed on the host client device 102 or the application server 114.

[0148] Fig.12 1 is a stereoscopic view of a wearable electronic device in the form of glasses 1200 according to some examples. Glasses 1200 are eyewear products including electronic products that operate within a network system for transmitting image and video content. In some examples, the wearable electronic device is referred to as AR glasses. Glasses 1200 may include a frame 1232 made of any suitable material, such as plastic or metal, including memory alloys of any suitable shape. Frame 1232 may have a front piece 1233, which may include a first lens or left lens, a display or optical element holder 1236, and a second lens or right lens, a display or optical element holder 1237 connected by a bridge 1238. Front piece 1233 further includes a left end 1241 and a right end 1242. The first optical element or left optical element 1244 and the second optical element or right optical element 1243 may be disposed in respective left optical element holders 1236 and right optical element holders 1237. Each of the optical elements 1243 and 1244 can be a lens, a display, a display assembly, or a combination thereof. In some examples, for example, the glasses 1200 are provided with an integrated near-eye display mechanism that enables, for example, displaying a preview image of visual media captured by the camera 1269 of the glasses 1200 to the user.

[0149] The frame 1232 further includes a left arm or temple piece 1246 and a right arm or temple piece 1247, which are coupled to the respective left end 1241 and right end 1242 of the front piece 1233 by any suitable means such as a hinge (not shown) so as to be coupled to the front piece 1233 or rigidly or fixedly fixed to the front piece 1233 so as to be integrated with the front piece 1233. Each of the temple piece 1246 and the temple piece 1247 may include: a first portion 1251 coupled to the respective end 1241 or end 1242 of the front piece 1233; and any suitable second portion 1252 for coupling to the ear of the user, such as a curved or arched piece. In one example, the front piece 1233 can be formed of a single piece of material to have an integrated or integral construction. In one example, the entire frame 1232 can be formed of a single piece of material to have an integrated or integral construction.

[0150] Eyeglasses 1200 include a computing device such as computer 1261, which can be of any suitable type to be carried by frame 1232 and, in one example, of a suitable size and shape to be at least partially disposed in one or more of temple pieces 1246, 1247. In one example, computer 1261 is of a size and shape similar to the size and shape of one of temple pieces 1246, 1247, and is thus disposed almost entirely, if not entirely, within the structure and confines of temple pieces 1246, 1247.

[0151] In one example, the computer 1261 can be disposed in both the temple piece 1246 and the temple piece 1247. The computer 1261 includes a low power circuit system, a high speed circuit system, a position circuit system, and a display processor. Various other examples can include these elements in different configurations or integrated together in different ways. Additional details of aspects of the computer 1261 can be implemented as described with reference to the following description.

[0152] The computer 1261 further includes a battery 1262 or other suitable portable power source. In one example, the battery 1262 is disposed in one of the temple pieces 1246 or 1247. Fig.12 In the illustrated glasses 1200, a battery 1262 is shown disposed in the left temple piece 1246 and electrically coupled to the remainder of the computer 1261 disposed in the right temple piece 1247 using connection 1274. The one or more input and output devices may include a connector or port (not shown) accessible from the exterior of the frame 1232 suitable for charging the battery 1262, a wireless receiver, transmitter or transceiver (not shown), or a combination of such devices.

[0153] The glasses 1200 include a digital camera 1269. Although two cameras 1269 are depicted, other examples contemplate the use of a single or additional (i.e., more than two) cameras 1269. For ease of description, various features related to the camera 1269 will be further described with reference to only a single camera 1269, but it will be understood that these features may apply to both cameras 1269 in suitable examples.

[0154] In various examples, the glasses 1200 may include any number of input sensors or peripherals in addition to the camera 1269. The front piece 1233 is provided with an outwardly facing, frontwardly facing front or outer surface 1266 that faces forward or away from the user when the glasses 1200 are mounted on the user's face, and an oppositely inwardly facing, rearwardly facing rear or inner surface 1267 that faces the user's face when the glasses 1200 are mounted on the user's face. Such sensors may include an inwardly facing video sensor or digital imaging module, such as the camera 1269 that may be mounted on the inner surface 1267 of the front piece 1233 or disposed within the inner surface 1267 or elsewhere on the frame 1232 to face the user, and an outwardly facing video sensor or digital imaging module, such as the camera 1269 that may be mounted on the outer surface 1266 of the front piece 1233 or disposed within the outer surface 1266 or elsewhere on the frame 1232 to face away from the user. Such sensors, peripherals, or peripheral devices may additionally include biometric sensors, position sensors, accelerometers, or any other such sensors. In some examples, a projector (not shown) is used to project an image on an inner surface of optical element 1243, optical element 1244 (or lens) to provide a mixed reality or augmented reality experience for a user of glasses 1200.

[0155] The glasses 1200 also include an example of a camera control mechanism or user input mechanism, which includes a camera control button mounted on the frame 1232 for tactile or manual engagement by the user. The camera control button provides a dual-mode or single-action mechanism, that is, the user can only set it between two states, an engaged state and a disengaged state. In this example, the camera control button is a button that is in the disengaged state by default, and the button can be pressed by the user to set it to the engaged state. When the camera control button is released from being pressed, it automatically returns to the disengaged state.

[0156] In other examples, the single action input mechanism may instead be provided by, for example, a touch sensitive button including a capacitive sensor mounted on the frame 1232 adjacent to a surface thereof for detecting the presence of a user's finger so as to set the touch sensitive button to an engaged state when the user touches the finger to a corresponding point on the outer surface 1266 of the frame 1232. It will be appreciated that the camera control button and the capacitive touch button described above are merely two examples of tactile input mechanisms for single action control of the camera 1269, and that other examples may employ different single action tactile control arrangements.

[0157] Computer 1261 is configured to perform the methods described herein. In some examples, computer 1261 is coupled to one or more antennas for receiving signals from a GNSS and circuitry for processing the signals, wherein the antennas and circuitry are housed in glasses 1200. In some examples, computer 1261 is coupled to one or more wireless antennas and circuitry for sending and receiving wireless signals, wherein the antennas and circuitry are housed in glasses 1200. In some examples, multiple sets of antennas and circuitry are housed in glasses 1200. In some examples, the antennas and circuitry are configured to receive signals based on a device such as Bluetooth. TM , Bluetooth Low Energy TM , IEEE 802, IEEE 802.11az / be, etc. In some examples, the PDR sensor is housed in the glasses 1200 and coupled to the computer 1261. In some examples, the glasses 1200 are VR headsets, wherein the optical elements 1243 and 1244 are opaque screens for displaying images to a user of the VR headset. In some examples, the computer 1261 is coupled to user interface elements such as a slide or touch pad 1276 and a button 1278. Long pressing the button 1278 resets the glasses 1200. The slide or touch pad 1276 and the button 1278 are used by the user to provide input to the computer 1261 and / or other electronic components of the glasses 1200. The glasses 1200 include one or more microphones 1282 coupled to the computer 1261. The glasses 1200 include one or more gyroscopes 1280.

[0158] Fig.13 A method 1300 for graphically assisting a task using an AR wearable device is shown according to some examples. The method 1100 may be performed by, for example, Fig.12 The operations may be performed by an AR wearable device 602 such as glasses 1200. One or more of the operations may be performed in whole or in part by other devices such as a messaging server system 108 or a portion of a client device 102.

[0159] The method 1300 begins at operation 1302 , where an image corresponding to a first user view of a real-world scene is captured by an image capture device of the AR wearable device. For example, the image display module 624 causes the image capture device 608 to capture the image 616 .

[0160] The method 1300 continues at operation 1304 by accessing data indicating a plurality of surfaces within the image and a plurality of locations of the plurality of surfaces in a memory of the AR wearable device. For example, the image display module 624 accesses the data 662 including the surface 632.

[0161] The method 1300 continues at operation 1306 by displaying an indication of the plurality of surfaces on a display of the AR wearable device, wherein a location of the indication of the plurality of surfaces on the display is based on the second user view of the real-world scene and the plurality of positions of the plurality of surfaces. For example, the image display module 624 displays an indication of the surface 632 on the display 610 of the AR wearable device 602, wherein the location of the indication is based on a current location 673 of the user view 672 and the location 656, and the current location 673 of the user view 672 may be different from the location 673 of the user view 672 when the image 616 was captured.

[0162] The method 1300 continues at operation 1308 by identifying a location of a point on a surface of the plurality of surfaces based on input from the user. For example, the UI module 634 identifies the user graphic 680 based on the focus area of ​​the user 644 and the input from the user 644 of the selection location 682. Figure 8 The position of "hole 1" 816 is 682.

[0163] Method 1300 continues at operation 1310 by displaying an indication of a point on the surface on a display of the AR wearable device, wherein the location of the point is based on the third user view of the real world scene and the location of the point. For example, continuing the example above, image display module 624 displays at the location of the third location 673 based on the user view 672 and the location 656 of the “hole 1” 816 Figure 8 "Hole 1" 816.

[0164] The method 1300 may include one or more additional operations. The operations of the method 1300 may be performed in a different order. One or more of the operations of the method 1300 may be optional. The method 1300 may be performed by the client device 102, the system 600, the glasses 1200, or another electronic device. Portions of the functions may be performed on a server computer or host. For example, the glasses 1200 may be coupled to a host client device 102 or an application server 114, and one or more of the operations may be performed on the host client device 102 or the application server 114.

[0172] With respect to cameras, client device 102 may have a camera system including, for example, a front-facing camera on a front surface of client device 102 and a rear-facing camera on a rear surface of client device 102. The front-facing camera may, for example, be used to capture still images and videos (e.g., “selfies”) of a user of client device 102, which may then be enhanced with the enhancement data (e.g., filters) described above. The rear-facing camera may, for example, be used to capture still images and videos in a more traditional camera mode, which are similarly enhanced with the enhancement data. In addition to the front-facing camera and the rear-facing camera, client device 102 may also include a 360° camera for capturing 360° photos and videos.

When executed by processor 1404, these instructions (e.g., instructions 1410) cause various operations to implement the disclosed examples.

[0178] The instructions 1410 may be sent or received over the network 1422 using a transmission medium via a network interface device (e.g., a network interface component included in the communication component 1438) and using any of several well-known transmission protocols (e.g., the Hypertext Transfer Protocol (HTTP)). Similarly, the instructions 1410 may be sent or received via a coupling (e.g., a peer-to-peer coupling) with the device 1424 using a transmission medium.

[0179] Software Architecture

[0180] Fig.1515 is a block diagram 1500 illustrating a software architecture 1504 that can be installed on any one or more of the devices described herein. The software architecture 1504 is supported by hardware such as a machine 1502 including a processor 1520, a memory 1526, and an I / O component 1538. In this example, the software architecture 1504 can be conceptualized as a stack of layers, where each layer provides specific functionality. The software architecture 1504 includes layers such as an operating system 1512, a library 1510, a framework 1508, and an application 1506. In operation, the application 1506 activates an API call 1550 through the software stack and receives a message 1552 in response to the API call 1550.

[0181] The operating system 1512 manages hardware resources and provides public services. The operating system 1512 includes, for example, a kernel 1514, services 1516, and drivers 1522. The kernel 1514 serves as an abstraction layer between the hardware and other software layers. For example, the kernel 1514 provides functions such as memory management, processor management (e.g., scheduling), component management, networking, and security settings. Services 1516 can provide other public services to other software layers. Drivers 1522 are responsible for controlling or interfacing with the underlying hardware. For example, drivers 1522 may include display drivers, camera drivers, or Low-power drivers, Flash drivers, Serial communication drivers (e.g., USB drivers), Drivers, audio drivers, power management drivers, etc.

[0182] The library 1510 provides a common low-level infrastructure used by the application 1506. The library 1510 may include a system library 1518 (e.g., a C standard library) that provides functions such as memory allocation functions, string manipulation functions, mathematical functions, etc. In addition, the library 1510 may include an API library 1524, such as: a media library (e.g., a library for supporting the presentation and manipulation of various media formats such as Moving Picture Experts Group-4 (MPEG4), Advanced Video Coding (H.264 or AVC), Moving Picture Experts Group Layer-3 (MP3), Advanced Audio Coding (AAC), Adaptive Multi-Rate (AMR) audio codec, Joint Photographic Experts Group (JPEG or JPG), or Portable Network Graphics (PNG)), a graphics library (e.g., an OpenGL framework for rendering in two dimensions (2D) and three dimensions (3D) in graphical content on a display), a database library (e.g., SQLite for providing various relational database functions), a web library (e.g., WebKit for providing web browsing functions), etc. The library 1510 may also include a variety of other libraries 1528 to provide many other APIs to the application 1506 .

[0183] The framework 1508 provides a common high-level infrastructure used by the applications 1506. For example, the framework 1508 provides various graphical user interface (GUI) functions, advanced resource management, and advanced location services. The framework 1508 may provide a wide range of other APIs that can be used by the applications 1506, some of which may be specific to a particular operating system or platform.

[0184] In an example, applications 1506 may include a home application 1536, a contacts application 1530, a browser application 1532, a reader application 1534, a location application 1542, a media application 1544, a messaging application 1546, a game application 1548, and a variety of other applications such as third-party applications 1540. Application 1506 is a program that executes the functions defined in the program. Various programming languages ​​can be used to create one or more of the applications 1506 constructed in various ways, such as an object-oriented programming language (e.g., Objective-C, Java, or C++) or a procedural programming language (e.g., C or assembly language). In a specific example, third-party application 1540 (e.g., a third-party application created by an entity other than the vendor of a particular platform using ANDROID TM or IOS TM Software Development Kit (SDK) applications can be developed for example IOS TM ANDROID TM , Mobile software running on a mobile operating system such as the iPhone or another mobile operating system. In this example, third-party applications 1540 can activate API calls 1550 provided by the operating system 1512 to facilitate the functions described herein.

[0185] Processing components

[0186] Now turn to Fig.16 , a diagrammatic representation of a processing environment 1600 is shown including a processor 1602, a processor 1606, and a processor 1608 (eg, a GPU, a CPU, or a combination thereof).

[0187] Processor 1602 is shown coupled to power source 1604 and includes (either permanently configured or temporarily instantiated) modules, namely image processing component 1610, graphical assistance component 1612, and user interface component 1614. Image processing component 1610 is activated to process image 616 in order to determine surface 632 and other information about surface 632. For example, ML module 620 processes image 616 to generate data 662 including surface 632 and accompanying information.

[0188] The graphical assistance component 1612 displays the user graphic 680, the AR graphic 686, and the surface 632 on the display 610 of the AR wearable device 602. For example, the image display module 624 displays the user graphic 680, the AR graphic 686, and the surface 632 on the display 610 to assist the user 644 in performing the task 623.

[0189] User interface component 1614 interacts with user 644 to determine user intent 636 of user 644. For example, UI module 634 processes tactile 646, gesture 648, voice 650, and positioning 652 inputs of user 644 to determine user intent 636. UI module 634 presents UI items such as app carousel 1008 on display 610. As shown, processor 1602 is communicatively coupled to both processor 1606 and processor 1608.

[0190] Glossary

[0191] Certain embodiments are described herein as including logic or several components, modules, or mechanisms. A module may constitute a software module (e.g., code embodied on a machine-readable medium or in a transmission signal) or a hardware module. A "hardware module" is a tangible unit that is capable of performing certain operations and may be configured or arranged in some physical manner. In various example embodiments, one or more computer systems (e.g., a stand-alone computer system, a client computer system, or a server computer system) or one or more hardware modules (e.g., a processor or a processor group) of a computer system may be configured by software (e.g., an application or an application portion) to be a hardware module that operates to perform certain operations described herein.

[0192] "Carrier signal" means any intangible medium capable of storing, encoding or carrying instructions for execution by a machine and includes a digital or analog communications signal or other intangible medium to facilitate transmission of such instructions. Instructions may be sent or received over a network using a transmission medium via a network interface device.

[0193] "Client Device" refers to any machine that interfaces with a communication 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, AR glasses, VR glasses, AR wearables, desktop computers, laptop computers, portable digital assistants (PDAs), smart phones, tablets, ultrabooks, netbooks, notebook computers, multiprocessor 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.

[0194] "Communications Network" means one or more parts of a network, which may be an ad hoc network, an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a wireless WAN (WWAN), a metropolitan area network (MAN), the Internet, a part of the Internet, a part of the Public Switched Telephone Network (PSTN), a Plain Old Telephone Service (POTS) network, a cellular telephone network, a wireless network, A network, other type of network, or a combination of two or more such networks. For example, the network or a portion of the network may include a wireless network or a cellular network, and the coupling may be a code division multiple access (CDMA) connection, a global system for mobile communications (GSM) connection, or other type of cellular or wireless coupling. In this example, the coupling may implement any of various types of data transmission technologies, such as single carrier radio transmission technology (1xRTT), evolution data optimized (EVDO) technology, general packet radio service (GPRS) technology, enhanced data rate GSM evolution (EDGE) technology, the third generation partnership project (3GPP) including 3G, fourth generation wireless (4G) network, universal mobile telecommunications system (UMTS), high speed packet access (HSPA), world wide interoperability for microwave access (WiMAX), long term evolution (LTE) standards, other data transmission technologies defined by various standard setting organizations, other long distance protocols, or other data transmission technologies.

[0195] "Component" refers to a device, physical entity or logic with boundaries defined by function or subroutine calls, branch points, APIs or other technologies that provide segmentation or modularization of specific processing or control functions. Components can be combined via their interfaces with other components to implement machine processing. Components can be packaged functional hardware units designed for use with other components, and are part of a program that generally performs specific functions in related functions. Components can constitute software components (e.g., codes embodied on machine-readable media) or hardware components. "Hardware components" are tangible units that can perform certain operations and can be configured or arranged in a certain physical manner. In various examples, one or more computer systems (e.g., independent computer systems, client computer systems or server computer systems) or one or more hardware components (e.g., processors or processor groups) of a computer system can be configured by software (e.g., applications or application parts) to operate to perform certain operations described herein. Hardware components can also be implemented mechanically, electrically or in any appropriate combination thereof. For example, a hardware component may include a dedicated circuit system or logic that is permanently configured to perform certain operations. The hardware component may be a dedicated processor, such as a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC). The hardware component may also include a programmable logic or circuit system that is temporarily configured to perform certain operations by software. For example, the hardware component may include software executed by a general-purpose processor or other programmable processor. Once configured by such software, the hardware component becomes a specific machine (or a specific component of a machine) that is uniquely customized to perform the configured function, and is no longer a general-purpose processor. It will be recognized that the decision to implement the hardware component mechanically, in a dedicated and permanently configured circuit or in a temporarily configured (e.g., configured by software) circuit system can be driven for cost and time considerations. Therefore, the phrase "hardware component" (or "hardware-implemented component") should be understood to include a tangible entity, whether it is an entity that is physically constructed, permanently configured (e.g., hardwired) or temporarily configured (e.g., programmed) to operate in some way or perform certain operations described herein. Considering an example where a hardware component is temporarily configured (e.g., programmed), each of the hardware components does not need to be configured or instantiated at any one time. For example, in the case where a hardware component includes a general-purpose processor that is configured by software to become a special-purpose processor, the general-purpose processor can be configured into different special-purpose processors (e.g., including different hardware components) at different times. The software configures one or more specific processors accordingly, so as to constitute a specific hardware component at one time and constitute different hardware components at different times. Hardware components can provide information to other hardware components and receive information from other hardware components. Accordingly, the described hardware components can be considered to be communicatively coupled.In the case of multiple hardware components being present at the same time, communication can be realized by signal transmission (for example, by appropriate circuits and buses) between or among two or more hardware components in the hardware components. In the example where multiple hardware components are configured or instantiated at different times, the communication between such hardware components can be realized, for example, by the storage and retrieval of information in the memory structure to which multiple hardware components have access rights. For example, a hardware component can perform an operation and store the output of the operation in a memory device coupled to it in communication. Then, another hardware component can access the memory device at a subsequent time to retrieve the stored output and process it. The hardware component can also initiate communication with an input device or an output device, and can operate on resources (for example, a collection of information). The various operations of the example methods described herein can be performed at least in part by one or more processors that are temporarily configured (for example, by software) or are permanently configured to perform related operations. Whether it is temporarily configured or permanently configured, such processors can constitute a processor-implemented component that operates to perform one or more operations or functions described herein. As used herein, "processor-implemented components" refer to hardware components implemented using one or more processors. Similarly, using one or more processors as hardware examples, the method described herein can be implemented at least in part by a processor. For example, at least some of the operations in the operation of the method can be performed by one or more processors or the parts implemented by the processor. In addition, one or more processors can also operate to support the execution of related operations in a "cloud computing" environment or operate as "software as a service" (SaaS). For example, at least some of the operations can be performed by a computer group (as an example of a machine including a processor), wherein these operations can be accessed via a network (for example, the Internet) and via one or more appropriate interfaces (for example, API). The execution of certain operations can be distributed between processors, not only resident in a single machine, but deployed across several machines. In some examples, a processor or a part implemented by a processor can be located in a single geographical location (for example, in a home environment, an office environment, or a server farm). In other examples, a processor or a part implemented by a processor can be distributed across several geographical locations.
