[0036] The augmented reality messenger system allows users to send augmented reality (AR) messages to friends on a messaging platform. AR messages include AR content bundled with audio messages (e.g., voice-recorded messages). AR messages can be delivered immediately or pre-scheduled to a specific moment defined by time, location, or object. The AR messenger system allows smartphone users to send AR messages. In some examples, the AR messenger system sends AR messages to friends wearing AR glasses. The AR messenger system overlays the AR message on the field of view of the AR glasses wearer and captures the wearer's reaction to the AR message. The AR messenger system also allows the wearer to share their reaction back to the sender. Although the following paragraphs describe sending AR messages to users wearing AR glasses, it will be understood that AR messages can be displayed on any other suitable computing device such as a smartphone.

[0037] Thus, the AR Messenger system allows for synchronous or asynchronous communication. AR messages can be sent instantly, or can be pre-scheduled. For example, a sender can schedule an AR message using a set of predefined conditions that, once triggered, will enable the AR message to be overlaid on the field of view of the receiver (e.g., a wearer of AR glasses). The set of predefined conditions includes, but is not limited to: location triggers, time period triggers, and visual marker triggers.

[0038] For example, a location trigger may be a physical address on a map. In some examples, a location trigger may be a geographic coordinate (e.g., latitude and longitude), a general city (e.g., San Francisco), or the intersection of two streets. Once the AR glasses wearer is at the physical address or within a predefined threshold of the physical address, the AR message will be triggered. A time period trigger may be a time range during which the AR message will be triggered. For example, the time range may be from 9:00AM to 10:30AM. The time range may be associated with the time zone of the AR glasses wearer (e.g., the recipient of the AR message). In another example, a time period trigger may be a specific time (e.g., 12:00PM). A visual marker trigger may be an object that appears in the field of view of the AR glasses wearer. For example, a visual marker trigger may be a specific sign at the workplace of the AR glasses wearer. Once a specific sign appears in the field of view of the AR glasses wearer, the visual marker trigger condition is met, and the AR message is overlaid on the field of view of the AR glasses wearer. In some examples, the visual marker trigger may be a specific color or texture.

[0039] Once the AR message is overlaid on the field of view of the AR glasses wearer, the AR messenger system allows the AR glasses wearer to record a reaction to the AR message. For example, the AR glasses wearer can record an audio message of the wearer's real-time reaction to the AR message overlaid on his field of view. The AR glasses wearer has the option to send the reaction back to the AR message sender. In some examples, the reaction is sent back to the AR message sender along with the AR message overlaid on the field of view of the AR glasses wearer.

[0040] Networked computing environment

[0041] 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).

[0042] The messaging client 104 can 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 to trigger functions) and payload data (e.g., text, audio, video, or other multimedia data). The messaging client 104 can also generate and send context-based AR messages between multiple client devices 102.

[0043] 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, the location of certain functions within the messaging client 104 or within the messaging server system 108 may be a design choice. For example, it may be technically preferred to initially deploy certain technologies and functions within the messaging server system 108, but later migrate the technologies and functions to the messaging client 104 where the client device 102 has sufficient processing power.

[0044] 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, geolocation information, media enhancements and overlays, message content persistence conditions, social network information, and live event information. The data exchange within the messaging system 100 is initiated and controlled by functions available via a user interface (UI) of the messaging clients 104.

[0045] 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 processes incoming network requests via the Hypertext Transfer Protocol (HTTP) and several other related protocols.

[0046] The application program interface (API) server 116 receives and sends message data (e.g., commands and message payloads) between the client device 102 and the application server 114. Specifically, the application program interface (API) server 116 provides a set of interfaces (e.g., routines and protocols) that the messaging client 104 can call or query to activate the functions of the application server 114. An application program interface (API) server 116 exposes various functions supported by application server 114, including: account registration; login functionality; sending messages from a particular messaging client 104 to another messaging client 104 via application server 114; sending media files (e.g., images or videos) from a messaging client 104 to messaging server 118 and for possible access by another messaging client 104; setting up a collection of media data (e.g., a story); retrieving a friend list of a user of client device 102; retrieving such a collection; retrieving messages and content; adding and removing entities (e.g., friends) from an entity graph (e.g., a social graph); locating friends in a social graph; and opening application events (e.g., related to messaging client 104).

[0047] The application server 114 hosts several server applications and subsystems, including, for example, a messaging server 118, an image processing server 122, and a social networking server 124. The messaging server 118 implements several message processing techniques and functions that are particularly 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 further 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 for such processing, other processor- and memory-intensive processing of data can also be performed on the server side by the messaging server 118.

[0048] The application server 114 also includes an image processing server 122 that is dedicated to performing various image processing operations, typically with respect to images or videos within the payload of messages sent from or received at the messaging server 118 .

[0049] The social network server 124 supports various social networking functions and services and makes these functions and services available to the messaging server 118. To this end, the social network server 124 maintains and accesses the entity graph 308 (e.g., Figure 3 ). Examples of functions and services supported by the social networking server 124 include identifying other users in the messaging system 100 who have a relationship with a particular user or who the particular user is "following," and identifying interests and other entities of a particular user.

[0050] Returning to the messaging client 104, the features and functions of the external resource (e.g., application 106 or applet) are available to the user via the interface of the 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 typically provided by a third party, but may also be provided by the creator or provider of the messaging client 104. The messaging client 104 receives a user's selection of an option to launch or access the features of such an external resource. The external resource may be an application 106 installed on the client device 102 (e.g., a "local app"), or a small-scale version of an application (e.g., a "small app") hosted on the client device 102 or located at a remote end of 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, native version of the application) and is implemented using a markup language document. In one example, a small-scale version of an 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 (e.g., .*ml files), an applet may also include scripting languages ​​(e.g., .*js files or .json files) and style sheets (e.g., .*ss files).

[0051] 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 the messaging client 104 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. A small-scale version of such an application can be launched or accessed via the messaging client 104, and in some examples, all portions of the small-scale application cannot be accessed outside the messaging client 104 or only limited portions of the small-scale application can be accessed outside the messaging client 104. The small-scale application can be launched by the messaging client 104 receiving a markup language document associated with the small-scale application, for example, from a third-party server 110 and processing such a document.

[0052] 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 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 (for example) communicates with the 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.

[0053] The messaging client 104 may notify the user of the client device 102 or other users (e.g., "friends") associated with such a user of activities occurring in one or more external resources. For example, the messaging client 104 may provide a notification to a participant in a conversation (e.g., a chat session) in the messaging client 104 about the current or recent use of an external resource by one or more members of a group of users. One or more users may be invited to join an active external resource or to start 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, each using a 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 item may be an interactive chat card that members of the chat may interact with, for example, to start 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.

[0054] 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 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).

[0055] System Architecture

[0056] Figure 21 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 augmentation system 208, a map system 210, a game system 212, an external resource system 214, and an AR messenger system 216.

[0057] 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 (e.g., for presentation and display) of messages and associated content via the messaging client 104 based on duration and display parameters associated with a message or collection of messages (e.g., a story). Additional details regarding the operation of the transient timer system 202 are provided below.

[0058] The collection management system 204 is responsible for managing groups 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 "galleries" or "event stories." Such collections can be made available for a specified time period (e.g., for 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 that a particular collection exists.

[0059] In addition, the collection management system 204 also includes a curation interface 206 that enables collection managers to manage and curate specific content collections. For example, the curation interface 206 enables event organizers to curate content collections related to specific events (e.g., remove inappropriate content or redundant messages). In addition, the collection management system 204 uses machine vision (or image recognition technology) and content rules to automatically curate content collections. In some examples, users can be paid compensation 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.

[0060] The enhancement system 208 provides various functions that enable a user to enhance (e.g., annotate or otherwise modify or edit) media content associated with a message. For example, the enhancement system 208 provides functions related to generating and publishing media overlays for messages processed by the messaging system 100. The enhancement system 208 is operable to supply media overlays or enhancements (e.g., image filters) to the messaging client 104 based on the geolocation of the client device 102. In another example, the enhancement system 208 is operable to supply media overlays to the messaging client 104 based on other information such as social network information of the user of the client device 102. The media overlay can include audio and visual content and visual effects. Examples of audio and visual content include pictures, text, logos, animations, and sound effects. Examples of visual effects include color overlays. Audio and visual content or visual effects can be applied to media content items (e.g., photos) at the client device 102. For example, the media overlay can include text or images that can be overlaid 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 enhancement system 208 uses the geolocation of the client device 102 to identify a media overlay that includes the name of the business at the geolocation of the client device 102. The media overlay may include other tags associated with the business. The media overlay may be stored in the database 126 and accessed by the database server 120.

[0061] In some examples, the enhancement system 208 provides a user-based publishing platform that enables a user to select a geolocation on a map and upload content associated with the selected geolocation. The user can also specify the environment 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 geolocation.

[0062] In other examples, the enhancement system 208 provides a merchant-based publishing platform that enables merchants to select specific media coverage associated with a geographic location via a bidding process. For example, the enhancement system 208 associates the media coverage of the highest bidding merchant with the corresponding geographic location for a predefined amount of time.

[0063] 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" in the context of the map, as well as media content (e.g., a collection of messages including photos and videos) generated by such friends. For example, a message posted by a user to the messaging system 100 from a particular geolocation can be displayed to the "friends" of a particular user on the mapping interface of the messaging client 104 within the context of that particular location on the map. The user can also share his or her location and status information with other users of the messaging system 100 (e.g., using an appropriate status avatar) via the messaging client 104, where the location and status information is displayed to the selected user within the context of the mapping interface of the messaging client 104.

[0064] 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 playing a particular game by sending an invitation to such other users from the messaging client 104. The messaging client 104 also supports both voice messaging and text messaging (e.g., chatting) within the context of game play, provides leaderboards for games, and also supports providing in-game rewards (e.g., game coins and items).

[0065] 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 (i.e., applications or applet). Each third-party server 110 hosts, for example, an application or a small-scale version of an application based on a markup language (e.g., HTML5) (e.g., a game application, a utility application, a payment application, or a ride-sharing application). The 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 program interface (API) having functions that can be called or stimulated by a web-based application. In some examples, the messaging server 118 includes a JavasScript 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.

[0066] The AR messenger system 216 sends an AR message from a first computing device to a second computing device. AR messages can be delivered immediately or pre-scheduled to a specific moment defined by a location trigger, a time period trigger, or a visual marker trigger. The AR messenger system 216 allows smartphone users to send AR messages. In some examples, the AR messenger system 216 sends AR messages to friends wearing AR glasses. The AR messenger system 216 overlays the AR message on the field of view of the AR glasses wearer and captures the wearer's reaction to the AR message. The AR messenger system 216 also allows the wearer to share their reaction back to the sender. In some examples, the AR messenger system 216 sends a message to another smartphone or any suitable computing device. Some aspects of the AR messenger system 216 can be operated on a messaging client. Some aspects of the AR messenger system 216 can be operated on an application server 114.

[0067] To integrate the functionality of the SDK into the 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 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 trigger certain functions of the SDK to integrate the features of the messaging client 104 into the web-based resource.

[0068] 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 retaining 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 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 call is sent as a message and a callback. Each SDK function is implemented by building a unique callback identifier and sending a message using the callback identifier.

[0069] 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., a box design or other graphics) of the web-based external resource in the messaging client 104. Once the user selects a visual representation or instructs the messaging client 104 to access a feature of a 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 feature of the web-based external resource.

[0070] 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 the login page or title screen, the messaging client 104 determines whether the external resource launched has been previously authorized to access the user data of the messaging client 104. In response to determining that the external resource launched has previously been authorized to access the user data of the messaging client 104, the messaging client 104 presents another graphical user interface including the functions and features of the external resource. In response to determining that the external resource launched has not previously been 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 a menu upwards (e.g., animating the menu to emerge from the bottom of the screen to the middle or other parts 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 allows the external resource to access the user data from the messaging client 104. In some examples, the external resource is authorized by the messaging client 104 to access the user data according to the OAuth 2 framework.

[0071] The messaging client 104 controls the type of user data shared with the external resource based on the type of external resource that is authorized. For example, an external resource including a full-scale application (e.g., application 106) is provided with access rights to a first type of user data (e.g., only a two-dimensional avatar of a user with or without different avatar features). As another example, an external resource including a small-scale version of an application (e.g., a web-based version of the application) is provided with access rights to a second type of user data (e.g., payment information, a two-dimensional avatar of a user, a three-dimensional avatar of a user, and an avatar with various avatar features). Avatar characteristics include different ways to customize the look and feel of an avatar (e.g., different poses, facial features, clothing, etc.).

[0072] Figure 3is a diagram showing a wearable device in the example form of glasses 331 for use in context-based augmented reality communications according to some example embodiments. Glasses 331 may include a frame 332 made of any suitable material such as plastic or metal, including any suitable shape memory alloy. Frame 332 may have a front piece 333, which may include a first or left lens, a display or optical element holder 336 and a second or right lens, display or optical element holder 337 connected by a bridge 338. Front piece 333 additionally includes a left end portion 341 and a right end portion 342. A first or left optical element 344 and a second or right optical element 343 may be disposed within respective left optical element holders 336 and right optical element holders 337. Each of optical elements 343, 344 may be a lens, a display (e.g., a transparent display), a display assembly, or a combination of the foregoing. In some embodiments, for example, the glasses 331 are provided with an integrated near-eye display mechanism that enables, for example, displaying to the user a preview image of visual media captured by the camera 367 of the glasses 331. In some embodiments, the integrated near-eye display mechanism allows for display of augmented reality content items such that the augmented reality content items are overlaid on a real-world environment viewable through the optical element 343 and the optical element 344.

[0073] The frame 332 further includes a left arm or temple piece 346 and a right arm or temple piece 347, which are connected to the corresponding left end 341 and right end 342 of the front piece 333 by any suitable means such as hinges (not shown) to be connected to the front piece 333 or rigidly or fixably fixed to the front piece 333, thereby being integral with the front piece 333. Each of the temple piece 346 and the temple piece 347 can include a first portion 351 connected to the corresponding end 341 or 342 of the front piece 333 and any suitable second portion 352 such as a curved or arched piece for connecting to the user's ear. In one embodiment, the front piece 333 can be formed of a single piece of material to have a unitary or one-piece construction. In one embodiment, the entire frame 332 can be formed of a single piece of material to have a unitary or one-piece construction.

[0074] The glasses 331 may include a device such as a computer 361, which may be of any suitable type to be carried by the frame 332, and in one embodiment, the device has a suitable size and shape to be at least partially disposed in one of the temple pieces 346 and 347. In one embodiment, the computer 361 has a size and shape similar to the size and shape of one of the temple pieces 346, 347, and is therefore almost completely, if not completely, disposed within the structure and confines of such temple pieces 346 and 347. In one embodiment, the computer 361 may be disposed in both temple pieces 346, 347. The computer 361 may include one or more processors with memory, wireless communication circuitry, and a power source. The computer 361 includes low-power circuits, high-speed circuits, and a display processor. Various other embodiments may include these elements in different configurations or integrated together in different ways.

[0075] The computer 361 further includes a battery 362 or other suitable portable power supply. In one embodiment, the battery 362 is disposed in one of the temple pieces 346 or 347. Figure 3 In the illustrated glasses 331, a battery 362 is shown disposed in the left temple piece 346 and electrically coupled to the remainder of the computer 361 disposed in the right temple piece 347 using a connector 374. The one or more I / O devices may include a connector or port (not shown) accessible from the exterior of the frame 332 suitable for charging the battery 362, a wireless receiver, transmitter or transceiver (not shown), or a combination of such devices. Given the limited size of the computer 361 and glasses 331, resource intensive operations such as video streaming may quickly drain the battery 362 and may be a strain on one or more processors of the computer 361 that may cause overheating.

[0076] The glasses 331 include a digital camera 367. Although two cameras 367 are depicted, other embodiments contemplate the use of a single or additional (i.e., more than two) cameras. For ease of description, various features associated with the camera 367 will be further described with reference to only a single camera 367, but it should be understood that these features may apply to both cameras 367 in suitable embodiments.

[0077] Consistent with some embodiments, glasses 331 are an example instance of client device 102 and may be worn by user 103-1. Additionally, in these embodiments, user 103-2 may view a live camera feed generated by camera 367 and interact with user 103-2 by causing virtual augmentations to be added to the real-world environment visible to user 103-1 via glasses 331. That is, one or more augmented reality content items corresponding to the virtual augmentations selected by user 103-2 may be displayed by an integrated near-eye display mechanism that enables the augmented reality content items to be overlaid on the real-world environment viewable through optical element 343 and optical element 344.

[0078] In various embodiments, the glasses 331 may include any number of input sensors or peripherals in addition to the camera 367. The front piece 333 is provided with: an outwardly facing, front-facing front or outer surface 366 that faces forward or away from the user when the glasses 331 are mounted on the user's face; and an opposite inwardly facing, rearwardly facing, or inner surface 369 that faces the face of the user (e.g., user 103-1) when the glasses 331 are mounted on the user's face. Such sensors may include: an inwardly facing video sensor or digital imaging module, such as a camera that may be mounted or disposed on or within the inner surface 369 of the front piece 333 or elsewhere on the frame 332 to face the user; and an outwardly facing video sensor or digital imaging module, such as a camera 367 that may be mounted or disposed on or within the outer surface 366 of the front piece 333 or elsewhere on the frame 332 to face away from the user. Such sensors, peripherals or peripherals may additionally include biosensors, position sensors, accelerometers or any other such sensors.

[0079] The glasses 331 also include an example embodiment of a camera control mechanism or user input mechanism that includes a camera control button mounted on the frame 332 for tactile or manual engagement by the user. The camera control button provides a dual-mode or single-action mechanism that can be used by the user between only two states, an engaged state and a disengaged state. In this example embodiment, the camera control button is a button that defaults to the disengaged state and 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.

[0080] In other embodiments, the single action input mechanism may instead be provided by, for example, a touch sensitive button including a capacitive sensor mounted on frame 332 adjacent to a surface of frame 332 for detecting the presence of a user's finger to set the touch sensitive button to an engaged state when the user touches the finger to a corresponding point on the outer surface of frame 332. It should be understood that the camera control button and capacitive touch button described above are merely two examples of tactile input mechanisms for single action control of camera 367, and other embodiments may employ different single action tactile control arrangements.

[0081] Data Architecture

[0082] Figure 4 is a schematic diagram illustrating a data structure 400 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 (e.g., as an object-oriented database).

[0083] Database 126 includes message data stored in message table 402. For any particular message, the message data includes at least message sender data, message recipient (or receiver) data, and payload. Figure 5 Additional details regarding information that may be included in a message and included in the message data stored in message table 402 are described.

[0084] The entity table 406 stores entity data and is linked (e.g., by reference) to the entity graph 408 and profile data 416. The entities whose records are stored in the entity table 406 may include individuals, corporate entities, organizations, objects, places, events, etc. Regardless of the entity type, any entity about which the messaging server system 108 stores data may be an identified entity. Each entity is provided with a unique identifier and an entity type identifier (not shown).

[0085] The entity graph 408 stores information about the relationships and associations between entities. As examples only, such relationships may be interest-based or activity-based social relationships, professional relationships (e.g., working in a common company or organization).

[0086] Profile data 416 stores multiple types of profile data about a particular entity. Based on the privacy settings specified by the particular entity, profile data 416 can be selectively used and presented to other users of the messaging system 100. In the case where the entity is a person, profile data 416 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. A 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 "status avatar" that presents a graphical representation of a state or activity that a user can choose to transmit at a particular time.

[0087] Where the entity is a group, profile data 416 for the group may similarly include one or more avatar representations associated with the group, in addition to the group name, members, and various settings for the relevant group (eg, notifications).

[0088] Database 126 also stores enhancement data, such as overlays or filters, in enhancement table 410. Enhancement data is associated with and applied to videos (whose data is stored in video table 404) and images (whose data is stored in image table 412).

[0089] In one example, a filter is an overlay displayed as an overlay on an image or video during presentation to a recipient user. Filters may be of various types, including filters selected by a user from a set of filters presented to a sending user by the messaging client 104 when the sending user is composing a message. Other types of filters include geolocation filters (also referred to as geofilters), which may be presented to a sending user based on geolocation. For example, a geolocation filter specific to a nearby or special location may be presented by the messaging client 104 within a user interface based on geolocation information determined by a global positioning system (GPS) unit of the client device 102.

[0090] Another type of filter is a data filter, which can be selectively presented to the sending user by the messaging client 104 based on other input or information collected during the message creation process by the client device 102. 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.

[0091] Other augmented data that may be stored in the image table 412 include augmented reality content items (eg, corresponding to application 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.

[0092] As described above, augmented data includes augmented reality content items, overlays, image transformations, AR images, and similar items involving modifications that can be applied to image data (e.g., videos or images). This includes real-time modifications, which modify the image when it is captured using the device sensor (e.g., one or more cameras) of the client device 102 and then display the image on the screen of the client device 102 with the modification. This also includes modifications to stored content, such as video clips in a gallery that can be modified. For example, in a client device 102 with access to multiple augmented reality content items, a user can use a single video clip with multiple augmented reality content items to see how 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 motion models can be applied to the same content. Similarly, real-time video capture can be used with the modifications shown to show how the video image currently captured by the sensor of the client device 102 will modify the captured data. Such data may simply be displayed on the screen without being stored in memory, or content captured by the device sensors may be recorded and stored in memory with or without modification (or both). In some systems, a preview feature may show how different augmented reality content items will look simultaneously within different windows of the display. For example, this may enable viewing multiple windows with different pseudo-random animations on the display simultaneously.

[0093] Thus, data and various systems using augmented reality content items or other such transformation systems that modify content using the data may involve detection of objects (e.g., faces, hands, bodies, cats, dogs, surfaces, objects, etc.), tracking these objects as they leave the field of view, enter the field of view in a video frame, and move around the field of view, and modifying or transforming them as they are tracked. In various examples, different methods for implementing such transformations may be used. Some examples may involve generating a three-dimensional mesh model of one or more objects, and using transformations and animated textures of the models within the video to implement the transformations. In other examples, tracking of points on an object may be used to place an image or texture (which may be two-dimensional or three-dimensional) at the tracked location. In yet another example, neural network analysis of a video frame may be used to place an image, model, or texture in content (e.g., a frame of an image or video). Thus, augmented reality content items refer to both images, models, and textures used to create transformations in content, as well as additional modeling and analysis information required to implement such transformations through object detection, tracking, and placement.

[0094] Real-time video processing can be performed using any type of video data (e.g., video streams, video files, etc.) stored in the memory of any type of computerized system. For example, a user can load a video file and store it in the memory of the device, or a video stream can be generated using the device's sensors. In addition, computer animation models can be used to process any object, such as a person's face and parts of a person's body, an animal, or a non-living thing (e.g., a chair, a car, or other object).

[0095] In some examples, when a specific modification is selected together with the content to be transformed, the computing device identifies the elements to be transformed, and then detects and tracks them if the elements are present in the video frame. The elements of the object are modified according to the modification request, thereby transforming the frame of the video stream. 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 feature points of each of the elements of the object are calculated (for example, using an active shape model (ASM) or other known methods). Then, a grid based on the feature points is generated for each of at least one element of the object. 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 of each element mentioned is aligned with the position of each element. Then, additional points are generated on the grid. A first group of first points is generated for each element based on the modification request, and a group of second points is generated for each element based on a group of first points and the modification request. Then, the frame of the video stream can be transformed by modifying the elements of the object based on the group of first points and the group of second points and the grid. In such a method, the background of the modified object can also be changed or distorted by tracking and modifying the background.

[0096] The transformation of changing some areas of the object using the elements of the object can be performed by calculating the feature points of each element of the object and generating a grid based on the calculated feature 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 of ​​each element with the position of each element of at least one element, and the properties of the area can be modified based on the modification request, thereby transforming the frame of the video stream. Depending on the specific modification request, the properties of the mentioned area can be transformed in different ways. Such modifications may involve: changing the color of the area; deleting at least some partial areas from the frame of the video stream; including one or more new objects in the area based on the modification request; and modifying or distorting the elements of the area or object. In various examples, any combination of such modifications or other similar modifications can be used. For certain models to be animated, some feature points can be selected as control points of the entire state space to be used to determine options for model animation.

[0097] 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.

[0098] Other methods and algorithms suitable for face detection may be used. For example, in some examples, landmarks are used to locate features, which 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 recognizable (for example, if the person has an eye patch), secondary landmarks can be used. Such a landmark identification process can be used for any such object. In some examples, a collection of landmarks forms a shape. The shape can be represented as a vector using the coordinates of the points in the shape. One shape is aligned with another shape using a similarity transformation (allowing translation, scaling, and rotation) that minimizes the average Euclidean distance between the shape points. The average shape is the average of the aligned training shapes.

[0099] In some examples, the landmark search begins with an average shape that aligns with the location and size of the face determined by the global face detector. Such a search then repeats the following steps until convergence occurs: tentative shapes are proposed by adjusting the positioning of shape points through template matching of the image texture around each point, and the tentative shapes are then conformed to the global shape model. In some systems, individual template matches are unreliable, and the shape model pools the results of weak template matches to form a stronger overall classifier. The entire search is repeated at each level of the image pyramid from coarse resolution to fine resolution.

[0100] The transformation system can capture an image or video stream on a client device (e.g., client device 102) and perform complex image manipulations locally on the client device 102 while maintaining an appropriate user experience, computational time, and power consumption. Complex image manipulations can include size and shape changes, emotion transfer (e.g., changing a face from a frown to a smile), state transfer (e.g., aging a subject, reducing apparent age, changing gender), style transfer, application of graphical elements, and any other suitable image or video manipulations enabled by a convolutional neural network that has been configured to execute efficiently on the client device 102.

[0101] 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 operating as part of a messaging client 104 operating on the client device 102. A transformation system operating within the messaging client 104 determines the presence of a face in the image or video stream and provides a modification icon associated with the computer animation model to transform the image data, or the computer animation model can be presented as associated with an interface described herein. The modification icon includes a change that can be a basis for modifying the face of the user within the image or video stream as part of the modification operation. Once the modification icon is selected, the transformation system initiates a process of transforming the image of the user to reflect the selected modification icon (e.g., generating a smiley face on the user). Once the image or video stream is captured and the specified modification is selected, the modified image or video stream can be presented in a graphical user interface displayed on the client device 102. The transformation system can implement a complex convolutional neural network on a portion of the image or video stream to generate and apply the selected modification. That is, once a modification icon is selected, the user can capture an image or video stream and be presented with the modification results in real time or near real time. In addition, when the video stream is being captured, the modification can be persistent and the selected modification icon remains toggled. Machine-taught neural networks can be used to implement such modifications.

[0102] The graphical user interface presenting the modifications performed by the transformation system can supply additional interactive options to the user. Such options can be based on the interface for initiating the selection of a specific computer animation model and content capture (e.g., initiated from a content creator user interface). In various examples, after the initial selection of the modification icon, the modification can be persistent. The user can turn on or off the modification by tapping or otherwise selecting the face modified by the transformation system, and store it for later viewing or browsing to other areas of the imaging application. In the case of multiple faces modified by the transformation system, the user can globally turn on or off the modification by tapping or selecting a single face modified and displayed in the graphical user interface. In some examples, each face in a group of multiple faces can be modified individually by tapping or selecting an individual face or a series of faces displayed in the graphical user interface, or such modifications can be switched individually.

[0103] The story table 414 stores data about a collection of messages and associated images, videos, or audio data organized 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 406). 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 an icon that the user can select to enable the sending user to add specific content to his or her personal story.

[0104] A collection may also constitute a "live story," which is a collection of content from multiple users created manually, automatically, or using a combination of manual and 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 co-located 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 a user by the messaging client 104 based on his or her location. The end result is a "live story" told from a community perspective.

[0105] Another type of content collection is called a "location story" that enables users whose client devices 102 are located within a specific geographic location (e.g., on a college or university campus) to contribute to a specific collection. In some examples, contributions to location stories may require a second degree of authentication to verify that the end user belongs to a specific organization or other entity (e.g., is a student on a university campus).

[0106] As described above, video table 404 stores video data, in one example, associated with messages whose records are maintained within message table 402. Similarly, image table 412 stores image data associated with messages whose message data is stored in entity table 406. Entity table 406 may associate various enhancements from enhancement table 410 with various images and videos stored in image table 412 and video table 404.

[0107] The database 126 may also store AR messages generated by the AR messenger system 216 .

[0108] Data communication architecture

[0109] Figure 5 is a schematic diagram illustrating the structure of a message 500 according to some examples, the message 500 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 500 is used to populate a message table 402 stored in a database 126, which is accessible by a messaging server 118. Similarly, the content of the message 500 is stored in memory as "in-flight" or "in-flight" data of a client device 102 or application server 114. The message 500 is shown to include the following example components:

[0110] Message identifier 502 : a unique identifier that identifies the message 500 .

[0111] Message text payload 504 : Text to be generated by a user via the user interface of the client device 102 and included in the message 500 .

[0112] Message image payload 506 : Image data captured by the camera component of the client device 102 or retrieved from the memory component of the client device 102 and included in the message 500 . The image data of the message 500 sent or received may be stored in the image table 412 .

[0113] • Message video payload 508 : Video data captured by the camera component or retrieved from the memory component of the client device 102 and included in the message 500 .

[0114] Video data for a sent or received message 500 may be stored in a video table 404 .

[0115] Message audio payload 510 : audio data captured by a microphone or retrieved from a memory component of the client device 102 and included in the message 500 .

[0116] Message enhancement data 512: Enhancement data (e.g., filters, stickers, or other annotations or enhancements) representing enhancements to be applied to the message image payload 506, message video payload 508, or message audio payload 510 of the message 500. The enhancement data for a sent or received message 500 may be stored in the enhancement table 410.

[0117] Message duration parameter 514: A parameter value indicating the amount of time in seconds that the content of a message (e.g., message image payload 506, message video payload 508, message audio payload 510) is to be presented to or made accessible to a user via the messaging client 104.

[0118] Message geolocation parameters 516: Geolocation data (e.g., latitude and longitude coordinates) associated with the content payload of the message. Multiple message geolocation parameter 516 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 506 or a specific video in a message video payload 508).

[0119] Message story identifier 518: An identifier value that identifies one or more content collections (e.g., a "story" identified in stories table 414) associated with a particular content item in message image payload 506 of message 500. For example, multiple images within message image payload 506 may each be associated with multiple content collections using identifier values.

[0120] Message tags 520: Each message 500 may be tagged with a number 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 506 depicts an animal (e.g., a lion), a tag value may be included within the message tags 520 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.

[0121] • Message sender identifier 522: 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 500 was generated and from which the message 500 was sent.

[0122] • Message recipient identifier 524: 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 500 is addressed.

[0123] The content (e.g., values) of the various components of message 500 may be pointers to locations in a table where content data values ​​are stored. For example, an image value in message image payload 506 may be a pointer (or address of a location) to a location within image table 412. Similarly, a value within message video payload 508 may point to data stored within video table 404, a value stored within message enhancement may point to data stored in enhancement table 410, a value stored within message story identifier 518 may point to data stored in story table 414, and values ​​stored within message sender identifier 522 and message recipient identifier 524 may point to user records stored within entity table 406.

[0124] Time-based access restriction architecture

[0125] Figure 6 is a schematic diagram illustrating an access restriction process 600, according to which access to content (e.g., a multimedia payload of a ephemeral message 602 and associated data) or a collection of content (e.g., a ephemeral message group 604) can be time-restricted (e.g., made ephemeral).

[0126] The ephemeral message 602 is shown associated with a message duration parameter 606, the value of which determines the amount of time that the messaging client 104 will display the ephemeral message 602 to the receiving user of the ephemeral message 602. In one example, depending on the amount of time specified by the sending user using the message duration parameter 606, the receiving user may view the ephemeral message 602 for up to 10 seconds.

[0127] The message duration parameter 606 and the message recipient identifier 524 are shown as inputs to a message timer 610, which is responsible for determining the amount of time that the transient message 602 is shown to a particular receiving user identified by the message recipient identifier 524. In particular, the transient message 602 is shown to the associated receiving user only for a period of time determined by the value of the message duration parameter 606. The message timer 610 is shown as providing an output to a more general transient timer system 202, which is responsible for the overall timing of displaying content (e.g., the transient message 602) to the receiving user.

[0128] Figure 6602 is included in a transient message group 604 (e.g., a collection of messages in a personal story or event story). The transient message group 604 has an associated group duration parameter 608, the value of which determines the duration for which the transient message group 604 is presented and accessible to users of the messaging system 100. For example, the group duration parameter 608 may be the duration of a concert, wherein the transient message group 604 is a collection of content related to the concert. Alternatively, a user (an owning user or a curator user) may specify the value of the group duration parameter 608 when performing setup and creation of the transient message group 604.

[0129] In addition, each ephemeral message 602 within the ephemeral message group 604 has an associated group participation parameter 612, the value of which determines the duration for which the ephemeral message 602 will be accessible within the context of the ephemeral message group 604. Thus, a particular ephemeral message group 604 may "expire" and become inaccessible within the context of the ephemeral message group 604 before the ephemeral message group 604 itself expires according to the group duration parameter 608. The group duration parameter 608, the group participation parameter 612, and the message recipient identifier 524 each provide inputs to a group timer 614, which is operable to first determine whether a particular ephemeral message 602 of the ephemeral message group 604 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 604 due to the message recipient identifier 524.

[0130] Thus, the group timer 614 is operable to control the total lifespan of the associated ephemeral message group 604 and the individual ephemeral messages 602 included in the ephemeral message group 604. In one example, each ephemeral message 602 within the ephemeral message group 604 remains viewable and accessible for a period of time specified by the group duration parameter 608. In another example, within the context of the ephemeral message group 604, a particular ephemeral message 602 may expire based on the group participation parameter 612. Note that even within the context of the ephemeral message group 604, the message duration parameter 606 may still determine the duration for which a particular ephemeral message 602 is displayed to a receiving user. Thus, the message duration parameter 606 determines the duration for which a particular ephemeral message 602 is displayed to a receiving user, regardless of whether the receiving user is viewing the ephemeral message 602 within or outside the context of the ephemeral message group 604.

[0131] The transient timer system 202 may also be operable to remove a particular transient message 602 from the transient message group 604 based on determining that the particular transient message 602 has exceeded the associated group participation parameter 612. For example, where the sending user has established a group participation parameter 612 of 24 hours from posting, the transient timer system 202 will remove the associated transient message 602 from the transient message group 604 after the specified 24 hours. The transient timer system 202 is also operable to remove a transient message group 604 when the group participation parameter 612 for each transient message 602 within the transient message group 604 has expired, or when the transient message group 604 itself has expired according to the group duration parameter 608.

[0132] In some use cases, the creator of a particular ephemeral message group 604 may specify an indefinite group duration parameter 608. In this case, the expiration of the group participation parameter 612 for the last remaining ephemeral message 602 within the ephemeral message group 604 will determine when the ephemeral message group 604 itself expires. In this case, a new ephemeral message 602 with a new group participation parameter 612 added to the ephemeral message group 604 effectively extends the life of the ephemeral message group 604 to be equal to the value of the group participation parameter 612.

[0133] In response to the transient timer system 202 determining that the transient message group 604 has expired (e.g., is no longer accessible), the transient timer system 202 communicates with the messaging system 100 (and, for example, in particular, the messaging client 104) to cause the indicia (e.g., icon) associated with the relevant transient message group 604 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 606 for a particular transient message 602 has expired, the transient timer system 202 causes the messaging client 104 to no longer display the indicia (e.g., icon or text identification) associated with the transient message 602.

[0134] Figure 7 is a flowchart of a method 700 for generating a context-based AR message according to some example embodiments. The operations described below may be performed by the AR messenger system 216. Although the described flowchart may show the operations as a sequential process, many of the operations may be performed in parallel or simultaneously. In addition, the order of the operations may be rearranged. When the operations of the process are completed, the process terminates. A process may correspond to a method, a procedure, an algorithm, etc. The operations of a method may be performed in whole or in part, may be performed in combination with some or all of the operations in other methods, and may be performed by any number of different systems (such as the systems described herein) or any portion thereof (such as a processor included in any system).

[0135] In operation 702, the AR messenger system 216 generates a contextual trigger defining a set of conditions for presenting an augmented reality content item on a second computing device. The contextual trigger may be generated at a first computing device. At operation 704, the AR messenger system 216 detects that at least one of the set of conditions is satisfied. In response to detecting that at least one condition has been satisfied, the AR messenger system causes the augmented reality content item to be presented at the second computing device. At operation 708, the AR messenger system 216 generates a user reaction based on multimedia data generated at the second computing device in response to the presentation of the augmented reality content item. The user reaction may include audio data. The user reaction may be a predefined length, such as 10 seconds. However, it should be understood that the generated reaction may be any suitable length of time. At operation 710, the AR messenger system 216 sends the user reaction to the first computing device. In some examples, the user reaction is generated during the presentation of the augmented reality content item at the second computing device. In some examples, the augmented reality content item is overlaid on the field of view of the user of the second computing device.

[0136] For example, a location trigger may be a physical address on a map. In some examples, a location trigger may be a geographic coordinate (e.g., latitude and longitude), a general city (e.g., San Francisco), or the intersection of two streets. Once the AR glasses wearer is at the physical address or within a predefined threshold of the physical address, the AR message will be triggered. A time period trigger may be a time range during which the AR message will be triggered. For example, the time range may be from 9:00AM to 10:30AM. The time range may be associated with the time zone of the AR glasses wearer (e.g., the recipient of the AR message). In another example, a time period trigger may be a specific time (e.g., 12:00PM). A visual marker trigger may be an object that appears in the field of view of the AR glasses wearer. For example, a visual marker trigger may be a specific sign at the workplace of the AR glasses wearer. Once a specific sign appears in the field of view of the AR glasses wearer, the visual marker trigger condition is met and the AR message is overlaid onto the field of view of the AR glasses wearer. In some examples, the visual marker trigger may be a specific color or texture.

[0137] In some examples, the AR messenger system 216 captures video from the second computing device. For example, the AR messenger system 216 captures a video of the recipient's field of view. The AR messenger system 216 determines that at least one of a set of conditions has been satisfied. In response to determining that at least one of the set of conditions has been satisfied, the AR messenger system 216 modifies the video with the augmented reality content item during the capture of the video. The AR messenger system 216 captures the recipient's reaction to the modified video and sends the recipient's reaction and the modified video to the first computing device.

[0138] The sender has the option of setting one or more triggers for the AR message via a graphical user interface of the first computing device. For example, the sender can set a location trigger. To determine that the location trigger has been met, the AR messenger system 216 uses one or more sensors to identify the current location of the second computing device and determines that the current location of the second computing device matches the location trigger. In some examples, the sender can include a radius around a predefined physical address defined by a location trigger that satisfies the location trigger condition. For example, the sender can define a location trigger to include the physical address of the recipient's home and a one-mile radius around their home. Therefore, if the recipient is at their residence or within one mile of their residence, the AR messenger system 216 determines that the location trigger condition is met.

[0139] If the sender sets a time period trigger, to determine that the time period trigger has been satisfied, the AR messenger system 216 identifies the current time during the capture of the video and determines that the current time falls within the time period trigger.

[0140] If the sender set a visual marker trigger, to determine that the visual marker trigger has been satisfied, the AR messenger system 216 identifies an object in the video during capture and determines that the object matches the visual marker trigger.

[0141] The recipient has the option of sending his reaction back to the sender. For example, the AR messenger system 216 can generate a user reaction. The AR messenger system 216 causes a pop-up window to be presented on the graphical user interface of the second computing device. The graphical user interface can display a visual prompt representing the option of sending the user reaction to the first computing device together with the modified video. For example, the visual prompt may include a thumbs-up indicating that the recipient wants to send their reaction or a thumbs-down indicating that the recipient does not want to send their reaction. The AR messenger system 216 detects the visual prompt based on the analysis of the image data generated by the first computing device. For example, the AR messenger system 216 analyzes the posture of the recipient based on the image data generated by the recipient's device. If the AR messenger system 216 recognizes the recipient's thumbs-up prompt (e.g., based on the image data captured using the recipient's computing device to determine that the recipient keeps his or her thumbs up), the AR messenger system 216 sends the recipient's reaction and the modified video to the first computing device. Therefore, the recipient's posture (e.g., visual prompt) confirms the sending of its user reaction. If the AR messenger system 216 recognizes a thumbs down cue, it does not send the recipient's reaction and the modified video to the first computing device. In some examples, the visual cue may include a first graphic indicating that the recipient needs to say "yes" to send their reaction, and a second graphic indicating that the recipient needs to say "no" to avoid sending their reaction. In some examples, the recipient's reaction is recorded as an audio file. In some examples, the recipient may only send their reaction back to the sender without sending the modified video.

[0142] Figure 8 is an illustration of an AR message according to some example embodiments. The AR messenger system 216 allows the user to interact locally with the AR message content, rather than viewing the AR message content as part of a photo or video. Item 802 is a view of a message thread between two users. In response to opening message 808, the content of message 804 is shown to the user. The content of message 804 includes AR message content. The user can be a wearer of AR glasses and view the AR message content on the AR glasses, as shown in item 806.

[0143] Fig. 9 is an illustration of an AR message according to some example embodiments. In some examples, the AR messenger system 216 allows the sender 906 of the AR message to see what the AR glasses wearer is looking at on the computing device of the sender 906 (as shown in item 902). For example, the sender can see that the wearer is at the beach during the winter and missed the snow day. The sender can generate an AR message with snowfall and send it to the wearer. As shown in item 904, the reality of the wearer 908 is enhanced by the snowfall.

[0144] FIG. 10A to FIG. 10C is an illustration of an AR messenger system according to some example implementations. At item 1002, an AR message sender sends a conditional AR message. At item 1004, the AR message is triggered. For example, at least one of the predefined conditions (e.g., a time period trigger, a location trigger, a visual marker trigger) is matched. At item 1006, the AR glasses wearer reacts to the AR message and sends his reaction back to the sender.

[0145] Item 1008 represents a user interface displayed on the sender's first computing device. The user interface 1008 is used to select a friend to whom the generated AR message is to be sent.

[0146] Item 1010 is a user interface for selecting a lens for an AR message. As shown in item 1010, the lens can include AR message content, such as an AR description of a dog. Item 1012 is a user interface for setting preferences for an AR message. The sender can select various conditions, such as whether to then tag an image to initiate an AR message, a specific time range for displaying an AR message, and a specific location required to display the message.

[0147] Item 1012 represents a user interface displayed on the sender's first computing device. For example, after the recipient views the AR message and captures his reaction, he can send the modified video and his reaction back to the sender. The sender can view the modified video and reaction as shown in item 1016 on the graphical user interface of the first computing device.

[0148] Figures 11 to 18 Operation of an AR messenger system according to some example embodiments is shown. Sender Caleb is using AR messenger system 216 to enhance the birthday experience of AR glasses wearer Steve. Since the sender and recipient are close friends, the sender is able to use AR messenger system 216 to provide a context-based AR message that further enhances the recipient's birthday experience.

[0149] Figures 11 to 14 FIG. 1 shows an AR message based on a visual marker trigger according to some example embodiments. Fig.11 In , the recipient 1104 enters the micro kitchen in his office and sees the poster 1102. The sender knows that the recipient starts his day by grabbing a cup of coffee in the micro kitchen in the office and specifies the poster 1102 as a visual marker trigger. Fig.12 In FIG. 1 , once the AR messenger system 216 recognizes the poster 1102 as the visual marker trigger 1202, the glasses of the receiver 1204 flash. Fig.13In response to the visual marker trigger, the AR messenger system 216 overlays the AR birthday candles 1302 onto the AR glasses of the recipient 1304. The recipient audibly reacts to the AR message 1304 and Fig.14 , the AR messenger system 216 displays a pop-up window 1402 with a voice prompt, which gives the recipient the option to send his reaction back to the sender. If the recipient says "yes", the AR messenger system 216 will send his reaction back to the sender, and if the recipient says "no", the AR messenger system 216 will not send the reaction back to the sender.

[0150] Figures 15 to 18 FIG. 1 shows an AR message based on a time period trigger and a location trigger according to some example embodiments. Fig.15 In , the recipient 1504 will leave his office and walk home. The sender knows that the recipient ends his workday between 6:00 PM EST and 8:00 PM EST every night. The sender also knows the physical location of the recipient's home and sets a location trigger that includes the physical address of the recipient's home and a 0.5 mile radius around the recipient's home. Fig.16 , the AR messenger system 216 recognizes that both the time period trigger and the location trigger have been satisfied, and the glasses of the receiver 1604 flash 1602. Fig.17 , the AR messenger system 216 overlays AR fireworks 1702 in the field of view of the recipient 1704. The recipient audibly reacts 1704 and Fig.18 , the AR messenger system 216 displays a pop-up window 1802 with a voice prompt, which gives the recipient 1804 the option to send his reaction back to the sender. If the recipient says "yes", the AR messenger system 216 will send his reaction back to the sender, and if the recipient says "no", the AR messenger system 216 will not send the reaction back to the sender.

[0151] Fig.19 1900 is a flowchart of a method 1900 for generating a context-based AR message according to some example embodiments. The operations described below may be performed by the AR messenger system 216. Although the described flowchart may show the operations as a sequential process, many of the operations may be performed in parallel or simultaneously. In addition, the order of the operations may be rearranged. When the operations of the process are completed, the process terminates. A process may correspond to a method, a procedure, an algorithm, etc. The operations of a method may be performed in whole or in part, may be performed in combination with some or all of the operations in other methods, and may be performed by any number of different systems (such as the systems described herein) or any portion thereof (such as a processor included in any system).

[0152] At operation 1902, the AR messenger system 216 receives a first user input indicating a selection of a user interface element corresponding to a recipient user. The user input may be specified via a user interface of a messaging application on a first computing device. For example, the sender may select a button corresponding to the recipient. At operation 1904, the AR messenger system 216 generates an augmented reality content item based on a second user input from the first computing device. The augmented reality content item may be the augmented reality content item described above with respect to Figure 4 The sender of the AR message (e.g., a user of the first computing device) can access the augmented reality content item to be sent as part of the AR message. In another example, the sender can generate a specific augmented reality content item via a graphical user interface of the first computing device.

[0153] At operation 1906, the AR messenger system 216 generates a contextual trigger for the generated augmented reality content item. The contextual trigger defines a set of conditions for presenting the generated augmented reality content item on the second computing device. In some examples, the contextual trigger is generated based on user input specified via a graphical user interface of the first computing device. In some examples, the first computing device is a smartphone and the second computing device is Figure 3 A pair of AR glasses described in .

[0154] At operation 1908, the AR messenger system 216 generates a multimedia message including audio data recorded at the first computing device. For example, the AR messenger system 216 may use one or more sensors of the first computing device to record the audio message. At operation 1910, the AR messenger system 216 detects that at least one of the set of conditions is satisfied. At operation 1912, in response to detecting that at least one of the set of conditions is satisfied, the AR messenger system 216 causes the augmented reality content item and the multimedia message to be presented at the second computing device. For example, the recipient may use a second computing device (e.g., AR glasses), with which the recipient can view his surroundings through an eyepiece. The augmented reality content item and the multimedia message are overlaid on the recipient's field of view. The AR messenger system 216 may record a video of the augmented reality content item and the multimedia message overlaid on the recipient's field of view.

[0155] The sender has the option of setting one or more triggers for the AR message via the graphical user interface of the first computing device. For example, the sender can set a location trigger. In order to determine that the location trigger has been met, the AR messenger system 216 uses one or more sensors to identify the current location of the second computing device, and determines that the current location of the second computing device matches the location trigger. In some examples, the sender can include a radius around a predefined physical address defined by the location trigger that satisfies the location trigger condition. For example, the sender can define the location trigger to include the physical address of the recipient's home and a radius of one mile around their home. Therefore, if the recipient is in their residence or within one mile of their residence, the AR messenger system 216 determines that the location trigger condition is met. In some examples, the location trigger is associated with a location category trigger. For example, the location trigger set by the sender can include a category of "restaurant". If the recipient is close to any location classified as a restaurant, the location trigger is met. The sender can define a location category trigger via the graphical user interface of the first computing device. The AR messenger system 216 uses one or more sensors to identify the location category associated with the current location of the second computing device, and determines that the location category associated with the current location matches the location category trigger.

[0156] If the sender sets a time period trigger, to determine that the time period trigger has been satisfied, the AR messenger system 216 identifies the current time during the capture of the video and determines that the current time falls within the time period trigger.

[0157] If the sender sets a visual tag trigger, to determine that the visual tag trigger has been satisfied, the AR messenger system 216 identifies an object in the video during capture and determines that the object matches the visual tag trigger. The visual tag trigger may be associated with a tag category trigger. For example, a visual tag trigger set by the sender may include a category of "Mona Lisa painting." If the recipient sees the Mona Lisa painting in his or her field of view, the visual tag trigger is satisfied.

[0158] In some examples, the AR messenger system 216 determines the probability that at least one of the conditions in the set of conditions will be satisfied, and presents a display element representing the probability on a graphical user interface of the first computing device. For example, when the sender establishes a context trigger, the AR messenger system 216 can calculate the probability that the context trigger will actually be triggered by the receiver. If the sender sets a more flexible positioning trigger, time trigger, and visual marker trigger, the probability that the context trigger will be triggered is higher. If the sender sets a more restrictive positioning trigger, time trigger, or visual marker trigger, the probability is lower. In some examples, the display element is updated in real time as the sender generates each condition of the context trigger. The display element can be a meter graphic with an arrow, which includes a green portion at one end, a yellow portion in the middle, and a red portion at the opposite end. A higher probability can be represented by an arrow pointing to the green portion. A lower probability can be represented by an arrow pointing to the red portion. Although described as using a meter graphic, it should be understood that any suitable graphic representing a probability range can be used.

[0159] In some examples, when generating a contextual trigger, the AR messenger system 216 receives a selection of a user interface element that defines a level of specificity for the contextual trigger. For example, a sender may select a toggle button from a first computing device that defines how flexible or strict the sender wants the conditions for triggering an AR message to be. Based on the selection, the AR messenger system 216 identifies the minimum number of conditions that must be detected in order to trigger the AR message and modify the video on the second computing device. For example, if the sender selects the “flexible” option on the toggle button, the AR messenger system 216 may identify at least one condition that must be met in order to trigger the AR message. If the sender selects the “specific” option on the toggle button, the AR messenger system 216 may identify a minimum of three conditions that must be met in order to trigger the AR message.

[0160] When generating a contextual trigger, the AR messenger system 216 can access data from the second computing device to further provide a more customized AR experience for the receiving user. For example, the AR messenger system 216 can access calendar data or a camera album on the second computing device. The accessed data (e.g., images on the calendar data or camera album) can be used to define at least one of a set of conditions. For example, the sender can access the recipient's calendar data to determine where the recipient will go that day and at what time he will go there. Therefore, the sender can use the recipient's calendar data to define location triggers and time triggers. In another example, the sender can access the recipient's camera album to determine how the items in the recipient's home look. The sender can view photos of the recipient's refrigerator and use the recipient's refrigerator as a visual marker trigger. Therefore, when the recipient sees his refrigerator in his field of view using the second computing device, the AR message will be triggered. In some examples, the AR messenger system 216 may need to verify access privileges to the first computing device to access data from the second computing device.

[0161] Figure 20 to Figure 24 is an illustration of a user interface within an AR messaging system according to some example implementations. At item 2002, a sender, via a graphical user interface of a first computing device, may select a recipient to send an AR message. At item 2004, the sender may generate an augmented content reality item to be sent as part of the AR message. At item 2006, the sender creates a contextual trigger for the AR message. At item 2006, the sender may also create an audio message to the selected recipient.

[0162] At item 2102, the sender can select two conditions for the AR message: when (e.g., a time period trigger) and where (e.g., a location trigger). At item 2104, the sender can generate a time period trigger for the AR message by setting a start time and an end time using user interface elements. At item 2106, the sender can set a location trigger by entering a physical address.

[0163] At item 2202, the sender may select an option to record an audio message. At item 2204, the sender may record the audio message. The sender may re-record the message or select the recorded message to send to the recipient. At item 2206, the sender may use a toggle interface element to select the level of granularity for the contextual trigger. For example, the sender may select an "I am clear" option to indicate that all conditions of the contextual trigger must be met for the AR message to be triggered.

[0164] At item 2302, the sender can generate a subsequent AR message and select a subsequent augmented reality content item. At item 2304, the sender can choose to use a visual marker trigger. At item 2306, the sender can select a visual marker to be used as a visual marker trigger. In some examples, the sender can upload an image from the first computing device to be used as a visual marker trigger.

[0165] At item 2402, the sender can generate a time period trigger for the AR message, and at item 2404, the sender can generate a location trigger by entering a physical address. At item 2406, the sender can use a toggle interface element to select the granularity level of the contextual trigger. For example, the sender can select the "I am flexible" option to indicate that at least one condition of the contextual trigger must be met for the AR message to be triggered.

[0166] Machine Architecture

[0167] Fig.252500 in which instructions 2510 (e.g., software, programs, applications, applet, app, or other executable code) may be executed to cause the machine 2500 to perform any one or more of the methods discussed herein. For example, the instructions 2510 may cause the machine 2500 to perform any one or more of the methods described herein. The instructions 2510 convert a general-purpose, unprogrammed machine 2500 into a specific machine 2500 that is programmed to perform the functions described and shown in the manner described. The machine 2500 may operate as a standalone device or may be coupled (e.g., networked) to other machines. In a networked deployment, the machine 2500 may operate as a server machine or a client machine in a server-client network environment or as a peer machine in a peer-to-peer (or distributed) network environment. The machine 2500 may include, but is not limited to, a server computer, a client computer, a personal computer (PC), a tablet computer, a laptop computer, a netbook, a set-top box (STB), a personal digital assistant (PDA), an entertainment media system, a cellular phone, a smart phone, a mobile device, a wearable device (e.g., a smart watch), a smart home device (e.g., a smart appliance), other smart devices, a web device, a network router, a network switch, a network bridge, or any machine capable of sequentially or otherwise executing instructions 2510 specifying actions to be taken by the machine 2500. In addition, although only a single machine 2500 is shown, the term "machine" should also be considered to include a collection of machines that execute instructions 2500 individually or jointly to perform any one or more of the methods discussed herein. For example, the machine 2500 may include any of the client device 102 (deleted) or a plurality of server devices forming part of the messaging server system 108 (deleted). In some examples, the machine 2500 may also include both a client and a server system, wherein certain operations of a particular method or algorithm are performed on the server side and certain operations of a particular method or algorithm are performed on the client side.

[0168] The machine 2500 may include a processor 2504, a memory 2506, and an input / output I / O component 2502 that may be configured to communicate with each other via a bus 2540. In an example, the processor 2504 (e.g., a central processing unit (CPU), a reduced instruction set computing (RISC) processor, a complex instruction set computing (CISC) processor, a graphics processing unit (GPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a radio frequency integrated circuit (RFIC), another processor, or any suitable combination thereof) may include, for example, a processor 2508 that executes instructions 2510 and a processor 2512. The term "processor" is intended to include multi-core processors, which may include two or more independent processors (sometimes referred to as "cores") that can execute instructions simultaneously. Although Fig.25 A multiprocessor 2504 is shown, but the machine 2500 may include a single processor with a single core, a single processor with multiple cores (e.g., a multi-core processor), multiple processors with a single core, multiple processors with multiple cores, or any combination thereof.

[0180] Software Architecture

[0181] Fig.262600 is a block diagram illustrating a software architecture 2604 that may be installed on any one or more of the devices described herein. The software architecture 2604 is supported by hardware such as a machine 2602 including a processor 2620, a memory 2626, and an I / O component 2638. In this example, the software architecture 2604 may be conceptualized as a stack of layers in which each layer provides specific functionality. The software architecture 2604 includes layers such as an operating system 2612, a library 2610, a framework 2608, and an application 2606. In operation, the application 2606 invokes an API call 2650 through the software stack and receives a message 2652 in response to the API call 2650.

[0182] The operating system 2612 manages hardware resources and provides public services. The operating system 2612 includes, for example, a kernel 2614, services 2616, and drivers 2622. The kernel 2614 serves as an abstraction layer between the hardware and other software layers. For example, the kernel 2614 provides functions such as memory management, processor management (e.g., scheduling), component management, networking, and security settings. Services 2616 can provide other public services to other software layers. Drivers 2622 are responsible for controlling or interfacing with the underlying hardware.

[0186] Glossary

[0187] "Carrier signal" refers to any intangible medium that can store, encode or carry instructions for execution by the machine and includes digital or analog communications signals or other intangible media to facilitate communication of such instructions. Instructions may be sent or received over a network using a transmission medium via a network interface device.

[0188] "Client Device" refers to any machine that interfaces with a communications network to obtain resources from one or more server systems or other client devices. A client device may be, but is not limited to, a mobile phone, a desktop computer, a laptop computer, a portable digital assistant (PDA), a smart phone, a tablet computer, an ultrabook, a netbook, a laptop computer, a multiprocessor system, a microprocessor-based or programmable consumer electronics product, a game console, a set-top box, or any other communications device that a user may use to access a network.

[0189] "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, The coupling may be a network, another 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 for GSM evolution (EDGE) technology, including the third generation partnership project (3GPP) of 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.

[0190] "Component" refers to a device, a physical entity, or logic with the following boundaries, which is defined by other technical definitions that provide partitioning or modularization for specific processing or control functions. Components can be docked with other components via their interfaces to perform machine processing. Components can be packaged functional hardware units designed for use with other components, and can be part of a program that generally performs specific functions in related functions. Components can constitute software components (e.g., codes implemented on machine-readable media) or hardware components. "Hardware components" are tangible units that can perform certain operations and can be configured or arranged in a certain physical manner. In various example implementations, one or more computer systems (e.g., independent computer systems, client computer systems, or server computer systems) or one or more hardware components of a computer system (e.g., processors or processor groups) can be configured by software (e.g., applications or application parts) to be hardware components for performing certain operations as described herein. Hardware components can also be implemented mechanically, electronically, or in any suitable combination thereof. For example, hardware components can include dedicated circuits or logic that are 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 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 should be understood that it can be decided whether to mechanically implement the hardware component in a dedicated and permanently configured circuit or in a temporarily configured (e.g., configured by software) circuit for cost and time considerations. Therefore, the phrase "hardware component" (or "hardware-implemented component") should be understood to include a tangible entity, that is, an entity that is physically constructed, permanently configured (e.g., hardwired) or temporarily configured (e.g., programmed) to operate in some way or perform certain operations described herein. Considering an example in which a hardware component is temporarily configured (e.g., programmed), it is not necessary to configure or instantiate each hardware component in the hardware component at any one time. For example, where a hardware component includes a general purpose processor that is configured by software to be a special purpose processor, the general purpose processor may be configured as different special purpose processors (e.g., including different hardware components) at different times. Thus, software configures one or more specific processors to, for example, constitute a specific hardware component at one time and to constitute different hardware components at different times. Hardware components may provide information to other hardware components and receive information from other hardware components. Thus, the described hardware components may be considered to be communicatively coupled.In the case of multiple hardware components being present at the same time, communication can be achieved by signal transmission between or among two or more hardware components (for example, through appropriate circuits and buses). In examples where multiple hardware components are configured or instantiated at different times, communication between such hardware components can be achieved, for example, by storing information in a memory structure accessed by multiple hardware components and retrieving information in the memory structure. For example, a hardware component can perform an operation, and the output of the operation is stored in a memory device coupled in communication. Then, other hardware components 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 in this article can be performed at least in part by one or more processors that are temporarily configured (for example, by software) or permanently configured to perform related operations. Whether it is a temporary configuration or a permanent configuration, such a processor can constitute a processor-implemented component that operates to perform one or more operations or functions described herein. As used herein, "processor-implemented components" refer to hardware components implemented using one or more processors. Similarly, the method described in this article can be implemented at least in part by a processor, wherein one or more specific processors are examples of hardware. For example, at least some operations 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 be operated to support the execution of related operations in the "cloud computing" environment or operate as "software as a service" (SaaS). For example, at least some operations in the operation can be performed by a computer group (as an example of a machine including a processor), wherein these operations can be accessed via a network (for example, the Internet) and via one or more appropriate interfaces (for example, API). The execution of some operations can be distributed between processors, not only resident in a single machine, but deployed across multiple machines. In some examples, a processor or the parts implemented by a processor can be located in a single geographic location (for example, in a home environment, an office environment or a server group). In other examples, a processor or the parts implemented by a processor can be distributed across several geographic locations.

[0191] "Computer-readable storage media" refers to both machine storage media and transmission media. Therefore, these terms include both storage devices / media and carrier / modulated data signals. The terms "machine-readable medium", "computer-readable medium" and "device-readable medium" mean the same thing and can be used interchangeably in this disclosure.

[0192] An "ephemeral message" is a message that can be accessed for a limited duration of time. An email message can be text, an image, a video, etc. The access time for an ephemeral message can be set by the sender of the message. Alternatively, the access time can be a default setting or a setting specified by the recipient. Regardless of the setting technique, the message is transient.

[0193] “Machine storage media” refers to a single or multiple storage devices and media (e.g., centralized or distributed databases, and associated caches and servers) that store executable instructions, routines, and data. Thus, the term should be considered to include, but is not limited to, solid-state memory and optical and magnetic media, including memory internal or external to the processor. Specific examples of machine storage media, computer storage media, and device storage media include: non-volatile memory, including, for example, semiconductor memory devices such as erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), FPGA, and flash memory devices; magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks. The terms “machine storage media,” “device storage media,” and “computer storage media” mean the same thing and are used interchangeably in this disclosure. The terms “machine storage media,” “computer storage media,” and “device storage media” expressly exclude carrier waves, modulated data signals, and other such media, at least some of which are encompassed by the term “signal media.”

[0194] “Non-transitory computer-readable storage medium” refers to tangible media capable of storing, encoding, or carrying instructions to be executed by a machine.

[0195] "Signal medium" refers to any intangible medium that is capable of storing, encoding or carrying instructions to be executed by a machine, and "signal medium" includes digital or analog communication signals or other intangible media to facilitate the communication of software or data. The term "signal medium" should be deemed to include any form of modulated data signal, carrier wave, etc. The term "modulated data signal" means a signal that has one or more of its characteristics set or changed in such a manner as to encode the information in the signal. The terms "transmission medium" and "signal medium" mean the same thing and may be used interchangeably in this disclosure.
