Interface with tactile and audio feedback responses

Abstract

The method for generating a tactile feedback response and an audio feedback response begins by causing a communication interface of a communication session to be displayed on a first user interface and a second user interface by a processor. The processor detects a first touch input on the first user interface and a second touch input on the second user interface. The processor monitors the position of the first touch input on the first user interface and the position of the second touch input on the second user interface. The processor determines the distance between the position of the first touch input on the first user interface and the position on the first user interface corresponding to the position of the second touch input on the second user interface. In response to determining that the distance is below a predetermined threshold, the processor causes the first user interface and the second user interface to generate an initial tactile feedback response and an initial audio feedback response. Other embodiments are described herein.

[0003] Consumer electronic devices are generally adapted to capture image, audio and video content. Using consumer electronic devices, users can communicate with each other via text messages, instant messaging, audio calls, video calls, etc. Users also use consumer electronic devices and messaging applications to share media content items such as pictures and videos, which reflects the overall demand for more visual communications.

[0004] As the number of social networking systems increases, each of the social networking systems faces the challenge of providing a user interface that attracts the user's attention and provides novel and attractive communication functions. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] When communicating on a messaging system, users can call each other and establish a voice call or a video call. Via the messaging system, users can share media content items such as audio, video, and pictures. However, it is obvious to users that communication on a messaging system or using a client device is not similar to face-to-face communication.

[0023] Embodiments of the present disclosure improve the functionality of a messaging system by incorporating haptic or tactile capabilities into the messaging system's communication interface. By adding the perception of touch to a user's communications on a messaging system, embodiments of the present disclosure come closer to providing a face-to-face communication experience and further allow a user to engage more deeply with their contacts on the messaging system.

[0024] Networked computing environment

[0025] 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 a client device 102, each instance hosting a number of applications including a messaging client 104 and other applications 106. In some examples, as discussed herein, the client device 102 includes a user interface (e.g., a display device, a touch screen, etc.) that generates a tactile feedback response based on touch input received during a video communication session. Each messaging client 104 is communicatively coupled to other instances of the messaging client 104 (e.g., hosted on corresponding 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 can also communicate with the locally hosted application 106 using an application program interface (API).

[0026] The messaging clients 104 are able to communicate and exchange data with other messaging clients 104 and messaging server systems 108 via the network 112. The data exchanged between the messaging clients 104 and between the messaging clients 104 and messaging server systems 108 includes functions (e.g., commands to activate functions) and payload data (e.g., text, audio, video, or other multimedia data).

[0027] 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 preferable 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.

[0028] 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 activated and controlled by functions available via a user interface (UI) of the messaging clients 104.

[0029] 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 112. The application server 114 is communicatively coupled to a database server 120, which facilitates access to a database 126 that stores data associated with messages processed by the application server 114. Similarly, a web server 128 is coupled to the application server 114 and provides a web-based interface to the application server 114. To this end, the web server 128 handles incoming network requests via the Hypertext Transfer Protocol (HTTP) and several other related protocols.

[0030] The application program interface (API) server 116 receives and sends message data (e.g., commands and message payloads) between the client device 102 and the application server 114. Specifically, the application program interface (API) server 116 provides a set of interfaces (e.g., routines and protocols) that can be called or queried by the messaging client 104 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 messaging client 104 to messaging server 118, and 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 within a social graph; and opening application (e.g., messaging client 104-related) events.

[0031] The application server 114 hosts multiple server applications and subsystems, including, for example, a messaging server 118, an image processing server 122, and a social network server 124. The messaging server 118 implements multiple message processing techniques and functions, particularly relating 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. Given the hardware requirements for other processor and memory intensive processing of data, such processing can also be performed on the server side by the messaging server 118.

[0032] The application server 114 also includes an image processing server 122 that is dedicated to performing various image processing operations, typically on images or videos within the payload of messages sent from or received at the messaging server 118 .

[0033] 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 social network server 124 include identifying other users in messaging system 100 that have a relationship with a particular user or that the particular user is "following," and also identifying interests and other entities of a particular user.

[0034] 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 usually provided by a third party, but can also be provided by the creator or provider of the messaging client 104. The messaging client 104 receives a user selection of an option to launch or access the features of such an external resource. The external resource can be an application 106 (e.g., a "local app") installed on the client device 102, or a small-scale version of an application (e.g., a "small application") hosted on the client device 102 or located at the far 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, the small-scale version of the application (e.g., a "small application") is a web-based markup language version of the application and is embedded in the messaging client 104. In addition to using markup language documents (eg, .*ml files), applet may include scripting languages ​​(eg, .*js files or .json files) and style sheets (eg, .*ss files).

[0035] 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, the application 106 locally installed on the client device 102 can be independent of the messaging client 104 and launched separately from the messaging client 104, such as by selecting an icon corresponding to the application 106 on a home screen of the client device 102. A small-scale version of such an application can be launched or accessed via the messaging client 104, and in some examples, no portion of the small-scale application (or only a limited portion) can be accessed outside of 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, such as from a third-party server 110, and processing such a document.

[0036] In response to determining that the external resource is a locally installed application 106, the messaging client 104 instructs the client device 102 to launch the external resource by executing the locally stored code corresponding to the external resource. In response to determining that the external resource is a web-based resource, the messaging client 104 (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.

[0037] 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 related to the current or recent use of an external resource by one or more members of a group of users to a participant in a conversation (e.g., a chat session) in the messaging client 104. One or more users may be invited to join an active external resource or to start an external resource that has been recently used but is currently inactive (in the group of friends). The external resource may provide the ability to share items, states, conditions, or locations in an external resource with one or more members of a group of users in a chat session to participants in the conversation who each use the corresponding messaging client 104. 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.

[0038] 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).

[0039] System Architecture

[0040] 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 to include a messaging client 104 and an application server 114. The messaging system 100 contains a number of subsystems that are supported on the client side by the messaging client 104 and on the server side by the application server 114. These subsystems include, for example, a transient timer system 202, a collection management system 204, an enhancement system 208, a map system 210, a game system 212, and an external resource system 214.

[0041] 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 incorporates a plurality of 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 a collection of messages (e.g., a story). Additional details regarding the operation of the transient timer system 202 are provided below.

[0042] The collection management system 204 is responsible for managing collections and collections of media (e.g., collections of text, image video, and audio data). Collections of content (e.g., messages, including images, videos, text, and audio) can be organized into "event galleries" or "event stories." Such collections can be made available for a specified time period, such as the duration of an event related to the content. For example, content related to a concert can be made available as a "story" for the duration of the concert. The collection management system 204 can also be responsible for publishing an icon that provides notification that a particular collection exists to the user interface of the messaging client 104.

[0043] In addition, the collection management system 204 includes a curation interface 206 that enables a collection manager to manage and curate a particular collection of content. For example, the curation interface 206 enables an event organizer to curate a collection of content related to a particular event (e.g., to remove inappropriate content or redundant messages). In addition, the collection management system 204 employs machine vision (or image recognition technology) and content rules to automatically curate content collections. In some examples, compensation may be paid to a user for including user-generated content in a collection. In such a case, the collection management system 204 operates to automatically pay such a user for using his or her content.

[0044] The enhancement system 208 provides various functions that enable users to enhance (e.g., annotate or otherwise modify or edit) media content associated with a message. For example, the enhancement system 208 provides functions related to the generation and publication of media overlays for messages processed by the messaging system 100. The enhancement system 208 is operable to provide media overlays or enhancements (e.g., image filters) to the messaging client 104 based on the geographic location of the client device 102. In another example, the enhancement system 208 is operable to provide media overlays to the messaging client 104 based on other information such as social network information of the user of the client device 102. The media overlay can include audio and visual content and visual effects. Examples of audio and visual content include pictures, text, logos, animations, and sound effects. Examples of visual effects include color overlays. Audio and visual content or visual effects can be applied to media content items (e.g., photos) at the client device 102. For example, the media overlay can include text or images that can be superimposed on photos taken by the client device 102. In another example, the media overlay includes a location identification overlay (e.g., Venice Beach), a live event name, or a business name overlay (e.g., Beach Cafe). In another example, the augmentation system 208 uses the geolocation of the client device 102 to identify a media overlay that includes a business name at the geolocation of the client device 102. The media overlay may include other tags associated with the business. The media overlay may be stored in the database 126 and accessed through the database server 120.

[0045] 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 context in which a particular media overlay should be provided to other users. The enhancement system 208 generates a media overlay including the uploaded content and associates the uploaded content with the selected geolocation.

[0046] In other examples, the enhancement system 208 provides a merchant-based publishing platform that enables merchants to select specific media overlays associated with a geographic location via a bidding process. For example, the enhancement system 208 associates the highest bidding merchant's media overlay with the corresponding geographic location for a predefined amount of time.

[0047] 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 a user icon or avatar (e.g., stored in the profile data 316) on a map to indicate the current location or past location of the user's "friends" and media content (e.g., a collection of messages including photos and videos) generated by such friends in the context of the map. For example, a message posted by a user to the messaging system 100 from a particular geolocation can be displayed to the "friends" of a particular user on the mapping interface of the messaging client 104 within the context of that particular location on the map. The user can also share his or her location and status information with other users of the messaging system 100 (e.g., using an appropriate status avatar) via the messaging client 104, where the location and status information is similarly displayed to selected users within the context of the mapping interface of the messaging client 104.

[0048] 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 from the messaging client 104 to such other users. The messaging client 104 also supports both voice and text messaging (e.g., chatting) within the context of gaming, provides leaderboards for gaming, and also supports providing in-game rewards (e.g., coins and items).

[0049] 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 small applications). Each third-party server 110, for example, hosts an application based on a markup language (e.g., HTML5) or a small-scale version of an application (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 activated by a web-based application. In some examples, the messaging server 118 includes a JavasScript library that provides access to a given external resource 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.

[0050] To integrate the functionality of the SDK into a web-based resource, the SDK is downloaded by the third-party server 110 from the messaging server 118, or received by the third-party server 110 in other ways. Once downloaded or received, the SDK is included as part of the application code of the web-based external resource. The code of the web-based resource can then call or activate certain functions of the SDK to integrate the features of the messaging client 104 into the web-based resource.

[0051] The SDK stored on the messaging server 118 effectively provides a bridge between external resources (e.g., applications 106 or small applications) and the messaging client 104. This provides users with a seamless experience of communicating with other users on the messaging client 104 while also 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 the communication between the third-party server 110 and the messaging client 104. In some examples, the WebViewJavaScriptBridge running on the client device 102 establishes two one-way communication channels between the external resources and the messaging client 104. Messages are sent asynchronously between the external resources and the messaging client 104 via these communication channels. Each SDK function call is sent as a message and a callback. Each SDK function is implemented by constructing a unique callback identifier and sending a message with the callback identifier.

[0052] 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 (such as 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.

[0053] 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 been previously authorized to access the user data of the messaging client 104, the messaging client 104 presents another graphical user interface of the external resource, which includes the functions and features of the external resource. In response to determining that the external resource launched has not been previously authorized to access the user data of the messaging client 104, after a threshold time period (e.g., 3 seconds) of displaying the login page or title screen of the external resource, the messaging client 104 slides up a menu for authorizing the external resource to access the user data (e.g., animating the menu to emerge from the bottom of the screen to the middle or other parts of the screen). The menu identifies the type of user data that the external resource will be authorized to use. In response to receiving the user selection of the accept option, the messaging client 104 adds the external resource to the list of authorized external resources and enables the external resource to access the user data from the messaging client 104. In some examples, the external resource is authorized by the messaging client 104 to access the user data according to the OAuth 2 framework.

[0054] The messaging client 104 controls the type of user data shared with the external resource based on the type of external resource that is authorized. For example, an external resource including a full-scale application (e.g., application 106) is provided with access to a first type of user data (e.g., only a two-dimensional avatar of a user with or without different avatar characteristics). As another example, an external resource including a small-scale version of an application (e.g., a web-based version of the application) is provided with access to a second type of user data (e.g., payment information, a two-dimensional avatar of a user, a three-dimensional avatar of a user, and an avatar with various avatar characteristics). Avatar characteristics include different ways to customize the look and feel of an avatar (e.g., different poses, facial features, clothing, etc.).

[0055] Data Architecture

[0056] Figure 3 is a diagram illustrating a data structure 300 that may be stored in a database 126 of a messaging server system 108 according to some examples. Although the contents of the database 126 are illustrated as including a plurality of tables, it will be appreciated that data may be stored in other types of data structures (e.g., as an object-oriented database).

[0057] The database 126 includes message data stored in the message table 302. For any particular message, the message data includes at least message sender data, message recipient (or receiver) data, and payload. Figure 4 Additional details regarding information that may be included in a message and included within the message data stored in message table 302 are described.

[0058] The entity table 306 stores entity data and is linked (e.g., referenced) to the entity graph 308 and profile data 316. The entity for which records are maintained within the entity table 306 may include a person, a corporate entity, an organization, an object, a place, an event, 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).

[0059] The entity graph 308 stores information about the relationships and associations between entities. As examples only, such relationships may be social relationships, professional relationships (e.g., working in a common company or organization) based on interests or activities.

[0060] Profile data 316 stores multiple types of profile data about a particular entity. Based on the privacy settings specified by the particular entity, profile data 316 can be selectively used and presented to other users of the messaging system 100. In the case where the entity is a person, profile data 316 includes, for example, a user name, phone number, address, settings (e.g., notification and privacy settings), and an avatar representation (or a collection of such avatar representations) selected by the user. A particular user can then selectively include one or more of these avatar representations within 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 status or activity that a user can choose to transmit at a particular time.

[0061] Where the entity is a group, profile data 316 for the group may similarly include one or more avatar representations associated with the group, in addition to the group name, members, and various settings for the relevant group (eg, notifications).

[0062] Database 126 also stores enhancement data, such as overlays or filters, in enhancement table 310. Enhancement data is associated with and applied to videos (data for videos is stored in video table 304) and images (data for images is stored in image table 312).

[0063] In one example, a filter is an overlay displayed as an overlay on an image or video during presentation to a recipient user. The filter can be of various types, including a user-selected filter from a set of filters presented to the 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 can be presented to the sending user based on geolocation. For example, a geolocation filter specific to a nearby or special location can 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.

[0064] 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.

[0065] Other augmented data that may be stored in the image table 312 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.

[0066] As described above, augmented data includes augmented reality content items, overlays, image transformations, AR images, and similar terms referring to 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 displayed on the screen of the client device 102 with the modification. This also includes modifications to stored content (e.g., video clips in a gallery that can be modified). For example, in a client device 102 that accesses multiple augmented reality content items, a user can use a single video clip with multiple augmented reality content items to see how different augmented reality content items will modify the stored clips. For example, by selecting different augmented reality content items for the same 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 being captured by the sensor of the client device 102 will modify the captured data. Such data may be displayed only on the screen and not 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 simultaneously display how different augmented reality content items will look within different windows in the display. For example, this may enable viewing multiple windows with different pseudo-random animations on the display at the same time.

[0067] Thus, data and various systems using augmented reality content items or other such transformation systems using such data to modify content may involve: detection of various objects (e.g., faces, hands, bodies, cats, dogs, surfaces, objects, etc.) in video frames, tracking of such objects as they leave, enter, and move around the field of view, and modification or transformation of such objects as they are tracked. In various examples, different methods for implementing such transformations may be used. Some examples may involve generating a three-dimensional mesh model of one or more objects, and using transformations and animated textures of the models within a video to implement the transformations. In other examples, tracking of points on an object may be used to place an image or texture (which may be two-dimensional or three-dimensional) at the tracked location. In yet other examples, neural network analysis of video frames may be used to place an image, model, or texture in content (e.g., an image or video frame). Thus, augmented reality content items involve both images, models, and textures used to create transformations in content, and additional modeling and analysis information required to implement such transformations using object detection, tracking, and placement.

[0068] Real-time video processing can be performed with any kind of video data (e.g., video streams, video files, etc.) stored in the memory of any kind of computerized system. For example, a user can load a video file and save it in the memory of the device, or a video stream can be generated using the device's sensors. In addition, any object, such as human faces and parts of the human body, animals, or non-living things (e.g., chairs, cars, or other objects) can be processed using computer animation models.

[0069] In some examples, when a specific modification is selected together with the content to be transformed, the element to be transformed is identified by a computing device, and then if the element to be transformed is between the frames of the video, the element to be transformed is detected and tracked. The elements of the object are modified according to the modification request, so the frames of the video stream are transformed. For different types of transformations, the transformation of the frames of the video stream can be performed by different methods. For example, for frame transformations that mainly involve changing the form of the elements of the object, the characteristic points of each element of the object are calculated (for example, using the Active Shape Model (ASM) or other known methods). Then, a grid based on the characteristic points is generated for each of at least one element of the object. The grid is used for the subsequent stages of tracking the elements of the object in the video stream. During the tracking process, the grid mentioned for each element is aligned with the 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 the 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 a group of first points, a group of second points and a grid. In such a method, the background of the modified object may also be changed or distorted by tracking and modifying the background.

[0070] In some examples, a transformation that changes certain areas of an object using the elements of the object can be performed by calculating characteristic points of each element of the object and generating a grid based on the calculated characteristic points. Points are generated on the grid, and then various areas based on these points are generated. Then, the elements of the object are tracked by aligning the area of ​​each element with the position of each of at least one element, and the properties of the area can be modified based on the modification request, so the frame of the video stream is transformed. Depending on the specific modification request, the properties of the mentioned area can be transformed in different ways. Such modifications may involve: changing the color of the area; removing at least part of the area 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 may be used. For certain models to be animated, some characteristic points may be selected as control points for determining the entire state space of options for model animation.

[0071] 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.

[0072] Other methods and algorithms suitable for face detection can be used. For example, in some examples, landmarks are used to locate features, and landmarks represent distinguishable points that exist in most of the images considered. For example, for facial landmarks, the location of the left eye pupil can be used. If the initial landmarks are not identifiable (for example, if the person has an eye mask), secondary landmarks can be used. Such a landmark identification process can be used for any such object. In some examples, a set 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 mean shape is the mean of the aligned training shapes.

[0073] In some examples, the landmark search begins with a mean shape that is aligned with the position and size of the face determined by a global face detector. Such a search then repeats the steps of suggesting tentative shapes by adjusting the positioning of shape points through template matching of the image texture around each point, and then conforming the tentative shapes to a global shape model until convergence occurs. In some systems, individual template 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 to fine resolution.

[0074] The transformation system can capture an image or video stream on a client device (e.g., client device 102) and perform complex image manipulations locally on the client device 102 while maintaining an appropriate user experience, computation time, and power consumption. Complex image manipulations can include size and shape changes, emotion conversions (e.g., changing a face from a frown to a smile), state transitions (e.g., aging an object, 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.

[0075] 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 within the image or video stream and provides a modification icon associated with the computer animation model to transform the data image, or the computer animation model can exist in association with an interface described herein. The modification icon includes the following changes: The changes can be the basis for modifying the face of the user within the image or video stream as part of the modification operation. Once the modification icon is selected, the transformation system initiates a process of transforming the image of the user to reflect the selected modification icon (e.g., generating a smiley face on the user). Once the image or video stream is captured and the specified modification is selected, the modified image or video stream can be presented in a graphical user interface displayed on the client device 102. The transformation system can implement a complex convolutional neural network on a portion of the image or video stream to generate and apply the selected modification. That is, a user can capture an image or video stream and once a modification icon is selected, the modification result is presented to the user 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.

[0076] The graphical user interface presenting the modifications performed by the transformation system can provide additional interactive options to the user. Such options can be based on the interface for initiating 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 being modified by the transformation system, and store it for later viewing or browsing to other areas of the imaging application. In the case of modifying multiple faces 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, or such modifications can be switched individually by tapping or selecting each face or a series of each face displayed in the graphical user interface.

[0077] The story table 314 stores data about a collection of messages and associated images, videos, or audio data that are compiled into a collection (e.g., a story or gallery). The creation of a particular collection can be initiated by a particular user (e.g., each user for whom a record is maintained in the entity table 306). A user can create a "personal story" in the form of a collection of content that has been created and sent / broadcasted by the user. To this end, the user interface of the messaging client 104 may include user-selectable icons to enable the sending user to add specific content to his or her personal story.

[0078] 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 the option of contributing content to a particular live story, for example, via a user interface of the messaging client 104. Live stories may be identified to the user by the messaging client 104 based on his or her location. The end result is a "live story" told from a group perspective.

[0079] Another type of content collection is called a "location story" that enables users whose client devices 102 are located within a specific geographic location (e.g., on a college or university campus) to contribute to a specific collection. In some examples, contributions to location stories may require secondary authentication to verify that the end user belongs to a specific organization or other entity (e.g., is a student on a university campus).

[0080] As mentioned above, the video table 304 stores video data, which in one example is associated with a message for which a record is maintained within the message table 302. Similarly, the image table 312 stores image data associated with a message whose message data is stored in the entity table 306. The entity table 306 may associate various enhancements from the enhancement table 310 with the various images and videos stored in the image table 312 and the video table 304.

[0081] Data communication architecture

[0082] Figure 4is a schematic diagram illustrating the structure of a message 400 generated by a messaging client 104 for transmission to another messaging client 104 or a messaging server 118 according to some examples. The content of a particular message 400 is used to populate a message table 302 stored in a database 126 accessible by a messaging server 118. Similarly, the content of the message 400 is stored in memory as "in-transit" or "in-flight" data of a client device 102 or application server 114. The message 400 is shown to include the following example components:

[0083] Message identifier 402 : a unique identifier that identifies the message 400 .

[0084] Message text payload 404 : Text to be generated by a user via the user interface of the client device 102 and included in the message 400 .

[0085] Message image payload 406 : Image data captured by a camera component of the client device 102 or retrieved from a memory component of the client device 102 and included in the message 400 . Image data for a message 400 sent or received may be stored in the image table 312 .

[0086] Message video payload 408 : Video data captured by the camera component or retrieved from the memory component of the client device 102 and included in the message 400 . The video data for a message 400 sent or received may be stored in the video table 304 .

[0087] Message audio payload 410 : audio data captured by a microphone or retrieved from a memory component of the client device 102 and included in the message 400 .

[0088] Message enhancement data 412: Enhancement data (e.g., filters, stickers, or other annotations or enhancements) representing enhancements to be applied to the message image payload 406, message video payload 408, or message audio payload 410 of the message 400. The enhancement data for a sent or received message 400 may be stored in the enhancement table 310.

[0089] Message duration parameter 414: A parameter value indicating the amount of time in seconds that the content of a message (eg, message image payload 406, message video payload 408, message audio payload 410) is to be presented to or made accessible to a user via the messaging client 104.

[0090] Message geolocation parameters 416: Geolocation data (e.g., latitude and longitude coordinates) associated with the content payload of the message. Multiple message geolocation parameter 416 values ​​may be included in the payload, with each of these parameter values ​​being associated with a content item included in the content (e.g., a specific image within a message image payload 406 or a specific video in a message video payload 408).

[0091] Message story identifier 418: An identifier value that identifies one or more content collections (e.g., a "story" identified in stories table 314) associated with a particular content item in message image payload 406 of message 400. For example, an identifier value may be used to associate multiple images within message image payload 406 with each of multiple content collections.

[0092] Message tags 420: Each message 400 may be tagged with a plurality of tags, each of which indicates the subject of the content included in the message payload. For example, where a particular image included in the message image payload 406 depicts an animal (e.g., a lion), a tag value may be included within the message tags 420 indicating the relevant animal. The tag value may be manually generated based on user input, or may be automatically generated using, for example, image recognition.

[0093] • Message sender identifier 422: An identifier (eg, a messaging system identifier, an email address, or a device identifier) ​​that indicates the user of the client device 102 on which the message 400 was generated and from which the message 400 was sent.

[0094] • Message recipient identifier 424: An identifier (eg, a messaging system identifier, an email address, or a device identifier) ​​that indicates the user of the client device 102 to which the message 400 is addressed.

[0095] The content (e.g., value) of each component of message 400 may be a pointer to a location in a table where the content data value is stored. For example, the image value in message image payload 406 may be a pointer (or address) to a location within image table 312. Similarly, the value within message video payload 408 may point to data stored within video table 304, the value stored within message enhancement 412 may point to data stored in enhancement table 310, the value stored within message story identifier 418 may point to data stored in story table 314, and the values ​​stored within message sender identifier 422 and message recipient identifier 424 may point to user records stored within entity table 306.

[0096] Real-time communication interface with tactile feedback response

[0097] Figure 5 Shown is a system 500 in which a real-time video communication interface with haptic response may be implemented according to some examples.

[0098] like Figure 5 As shown in FIG. 5 , the system 500 may include multiple client devices 102. Each client device 102 includes a user interface (e.g., a display device or a touch screen) to receive touch input from a user. Although not shown, the system 500 may also include a server (e.g., Figure 1 The messaging server system 108).

[0099] Figure 6 Detail of one of the client devices 102 in the system 500 is shown according to an example implementation. It is understood that the client device 102 in the system 500 may include Figure 6 The client device 102 may be a Fig.11 The machine 1100 shown in .

[0100] like Figure 6 As shown in FIG, the client device 102 includes a housing 604, a camera 602 having a camera opening, a microphone 606, and a display 608. Figure 6 Not shown, but the client device 102 may also include a camera lens, a camera image sensor, a processor, a memory, and a communication interface.

[0101] In one embodiment, the camera opening is an opening in the housing 604 that is coupled to a camera lens of a camera 602 included in the client device 102. In one embodiment, the camera opening can be a window that allows the camera lens to capture images or video content (e.g., media content items). The camera 602 may include a camera lens and an image sensor. The camera lens may be a perspective camera lens or a non-perspective camera lens. The non-perspective camera lens may be, for example, a fisheye lens, a wide-angle lens, an omnidirectional lens, etc. The image sensor captures an image or digital video through the camera lens. The image may also be a still image frame or a video including multiple still image frames.

[0102] In one example, microphone 606 (or multiple microphones) can be an air interface sound collecting device that converts sound into an electrical signal. More specifically, a microphone is a transducer that converts sound pressure into an electrical signal (e.g., an acoustic signal). The microphone can be a digital or analog micro-electromechanical system (MEMS) microphone. The acoustic signal generated by microphone 606 can be a pulse density modulated (PDM) signal.

[0103] The display device 608 included in the client device 102 may be a touch screen. As discussed herein, the display device 608 may display a user interface and a communication interface.

[0104] The user may interact with the display device 608 by touching a location on the display device 608. The user may interact with the display device 608 by performing contact with the display device 608. Examples of contact with the display device 608 include single-clicking, pressing, or touching a location on the display device 608, double-clicking or pressing a location on the display device 608, pressing and maintaining contact with the display device 608 for a period of time. In one example, the user may also draw a drawing input (e.g., a line, pattern, or portion of a scribble or drawing) by touching the display device 608 at a starting location on the display device 608, maintaining contact with the display device 608 while drawing the drawing input, and leaving the display device 608 at an ending location on the display device 608 to complete the drawing input.

[0105] like Figure 5 As shown in FIG. 5 , system 500 may include a first client device 102 and a second client device 102 .

[0106] When a communication session between the first client device 102 and the second client device 102 is established, the system 500 causes a communication interface of the communication session to be displayed on the display devices 608 of the first client device 102 and the second client device 102. The communication session may be a video communication session between the first client device 102 and the second client device 102. In one example, the video communication session is real-time.

[0107] In one example, the system 500 detects a first touch input on a display 608 of a first client device 102 and a second touch input on a display 608 of a second client device 102. The system 500 monitors the location of the first touch input and the location of the second touch input. The system 500 determines a distance between the location of the first touch input on the display 608 of the first client device 102 and a location on the display 608 of the first client device 102 that corresponds to the location of the second touch input on the display 608 of the second client device 102.

[0108] System 500 can cause display 608 of first client device 102 and display 608 of second client device 102 to generate haptic feedback responses based on distance. In one example, the haptic feedback response increases in intensity or speed as distance decreases and decreases in intensity or speed as distance increases.

[0109] Thus, the haptic feedback responses are based on the user touch inputs synchronized in time and location on their respective client devices 102. The varying intensity (or force) or speed of the generated haptic feedback responses also guides the user to locations on the screen that other users are touching.

[0110] Figure 7 Details of the client device 102 as a head mounted device 700 are shown according to an example implementation.

[0111] Figure 7 A perspective view of a head mounted device 700 is shown according to an example embodiment. Figure 7 , the head-mounted device 700 is a pair of glasses. In some embodiments, the head-mounted device 700 may be sunglasses or goggles. Some embodiments may include one or more wearable devices (such as a pendant with an integrated camera that is integrated with, communicates with, or is coupled to the head-mounted device 700 or the client device 102). Any desired wearable device may be used in conjunction with embodiments of the present disclosure, such as a watch, headphones, a wristband, earbuds, clothing (such as a hat or jacket with integrated electronics), a clip-on electronic device, or any other wearable device. It is understood that, although not shown, one or more portions of the system included in the head-mounted device 700 may be included in a client device 102 (e.g., Fig.11 In the machine 1100).

[0112] exist Figure 7 , the head mounted device 700 is a pair of glasses including a frame 706, the frame 706 including a frame (or rim) coupled to two stems (or temples) via hinges and / or end pieces, respectively. The frame of the frame 706 carries or accommodates a pair of lenses (e.g., lens 708a and lens 708b). The frame 706 includes a first (e.g., right) side coupled to the first stem and a second (e.g., left) side coupled to the second stem. The first side of the frame 706 is opposite to the second side.

[0113] The head mounted device 700 also includes a camera module (not shown) and at least one image sensor, the camera module including a camera lens (e.g., camera lens 704a, camera lens 704b). The camera lens 704a and the camera lens 704b may be perspective camera lenses or non-perspective camera lenses. The non-perspective camera lenses may be, for example, fisheye lenses, wide-angle lenses, omnidirectional lenses, etc. The image sensor captures digital video through the camera lens 704a and the camera lens 704b. The image may also be a still image frame or a video including a plurality of still image frames. The camera module may be coupled to the frame 706. As shown in FIG. Figure 7 As shown in FIG, frame 706 is coupled to camera lens 704a and camera lens 704b so that the camera lenses (e.g., camera lens 704a, camera lens 704b) face forward. Camera lens 704a and camera lens 704b can be perpendicular to lens 708a and lens 708b. The camera module can include dual front cameras that are separated by the width of frame 706 or the width of the head of the user of head mounted device 700.

[0114] exist Figure 7 , two handles (or temples) are coupled to microphone housing 702a and microphone housing 702b, respectively. The first handle and the second handle are coupled to opposite sides of the frame 706 of the head mounted device 700. The first handle is coupled to the first microphone housing 702a, and the second handle is coupled to the second microphone housing 702b. The microphone housing 702a and the microphone housing 702b can be coupled to the handles between the frame 706 and the location of the temple tip. The microphone housing 702a and the microphone housing 702b can be located on either side of the temple of the user when the user wears the head mounted device 700.

[0115] like Figure 7 As shown in , microphone housing 702a and microphone housing 702b enclose multiple microphones (not shown) including microphone 606. Microphone 606 can be one or more microphones. A microphone is an air interface sound collecting device that converts sound into an electrical signal. More specifically, a microphone is a transducer that converts sound pressure into an electrical signal (e.g., an acoustic signal). The microphone can be a digital or analog micro-electromechanical system (MEMS) microphone. The acoustic signal generated by the microphone can be a pulse density modulation (PDM) signal.

[0116] In one embodiment, a pair of lenses (e.g., lens 708a and lens 708b) in the head mounted device 700 may also include a display device that can display a communication interface. In some examples, the head mounted device 700 may be a virtual reality (VR) glasses.

[0117] Some embodiments may include one or more wearable devices, such as a glove with the ability to provide tactile feedback that is integrated with, in communication with, or coupled to the client device 102. Any desired wearable device may be used in conjunction with embodiments of the present disclosure, such as a watch, glasses, goggles, virtual reality (VR) goggles, headphones, wristbands, earbuds, clothing (such as a hat or jacket with integrated electronics), clip-on electronics, or any other wearable device.

[0118] Fig. 8A , Figure 8B , Figure 8C as well as Fig.8D An example of a communication interface being displayed on the first user interface 802 of the first client device 102 according to one example implementation is shown. It is understood that the communication interface displayed on the second user interface 802 of the second client device 102 may include similar elements.

[0119] exist Fig. 8A , Figure 8B , Figure 8C as well as Fig.8D In the example shown in , the communication session is a real-time video communication session between a first user of the first client device 102 and a second user of the second client device 102. On the first user interface 802, a real-time image of the second user is displayed. Similarly, the second user interface 802 can display a real-time image of the first user during the communication session.

[0120] The first user of the first client device 102 and the second user of the second client device 102 are online in the communication session. In other words, the two users have communication interfaces displayed on their client devices 102, so that the two users are online or active in the communication session.

[0121] In one example, a processor in system 500 detects a first touch input on a first user interface and a second touch input on a second user interface. The processor can monitor the position of the first touch input on the first user interface 802 and the position of the second touch input on the second user interface 802.

[0122] like Fig. 8A , Figure 8B , Figure 8C ,as well as Fig.8DAs shown in , the communication interface displayed on the first user interface 802 may include a first indicator element 804 and a second indicator element 806. The processor may cause the first user interface 802 to display the first indicator element 804 at the location of the first touch input, and to display the second indicator element 806 at a location on the first user interface 802 corresponding to the location of the second touch input on the second user interface 802. Similarly, the processor may cause the second user interface 802 to display the first indicator element 804 at the location of the second touch input, and to display the second indicator element at a location on the second user interface 802 corresponding to the location of the first touch input on the first user interface 802.

[0123] like Fig. 8A , Figure 8B , Figure 8C ,as well as Fig.8D As shown in FIG. 8 , the distance between the first indicator element 804 and the second indicator element 806 on the first user interface 802 is Fig. 8A CUHK, Figure 8B decreases in and Figure 8C and Fig.8D Decrease again.

[0124] The processor can determine the distance between the location of the first touch input on the first user interface 802 (e.g., the location of the first indicator element 804) and the location on the first user interface 802 corresponding to the location of the second touch input on the second user interface 802 (e.g., the location of the second indicator element 806).

[0125] The processor may cause the first user interface 802 and the second user interface 802 to generate a tactile feedback response based on the distance. In one example, the tactile feedback response increases in strength or speed as the distance decreases, and decreases in strength or speed as the distance increases.

[0126] In one example, the processor may cause the first user interface 802 and the second user interface 802 to generate an audio feedback response based on the distance. The processor may also cause the first user interface 802 and the second user interface 802 to generate a combination of a tactile feedback response and an audio feedback response based on the distance.

[0127] In one example, the audio feedback response increases in complexity or volume as the distance decreases, and decreases in complexity and volume as the distance increases. In another example, the audio feedback response decreases in volume as the distance decreases, and increases in volume as the distance increases. The audio feedback response can also be a song, and as the distance decreases, more instruments are added to the song.

[0128] In one example, the processor can determine whether the distance is below a predetermined threshold. When the distance is below a predetermined threshold, the user touch input on its respective client device 102 is determined to be synchronized in time and position. In response to determining that the distance is below a predetermined threshold, the processor can generate a reward tactile feedback response (or enhanced tactile feedback response) for the first user interface 802 and the second user interface 802. In one example, the reward tactile response (or enhanced tactile feedback response) is different from the tactile feedback response (or initial tactile feedback response) to indicate that the user is synchronized on its touch input. In other words, when the user is touching the same corresponding position on its client device 102 at the same time, the user is provided with a reward tactile response (or enhanced tactile feedback response).

[0129] In one example, the tactile feedback response includes a first vibration pattern, and the reward tactile feedback response (or enhanced tactile feedback response) includes a second vibration pattern that is different from the first vibration pattern. The reward tactile feedback response (or enhanced tactile feedback response) can be a stronger (or more intense) vibration pattern or a faster vibration pattern. In one example, the tactile feedback response can be a vibration pattern that simulates a heartbeat. The heartbeat can be a light heartbeat that becomes stronger as the distance decreases (e.g., the first touch input and the second touch input become closer), or it can be a strong heartbeat that becomes lighter as the distance increases (e.g., the first touch input and the second touch input become farther away).

[0130] In response to determining that the distance is below a predetermined threshold, in one example, the processor causes the first user interface 802 and the second user interface 802 to generate the following Figure 8C 808 for the communication interface shown in . Enhancement 808 may include overlays, visual effects, animations, sound effects, or any combination thereof. In one example, enhancement 808 is temporarily generated for a predetermined period of time.

[0131] In one example, if the distance is below a predetermined threshold, the processor can also enable the first user interface 802 and the second user interface 802 to generate an enhanced audio feedback response. The enhanced audio feedback response is different from the audio feedback response, and is synchronous to indicate that the user is in its touch input. In other words, when the user touches the same corresponding position on the client device 102 simultaneously, the user is provided with an enhanced audio feedback response. For example, the enhanced audio feedback response can be enhanced compared to the (initial) audio feedback response in terms of complexity and volume. In the example where the audio feedback response is a song with only one musical instrument, when the distance is below a predetermined threshold, the enhanced audio feedback response can be a complete song that all musical instruments can hear.

[0132] exist Fig.8DIn the example shown in FIG. 8A and FIG. 9B , the first user and the second user may touch the first user interface 802 and the second user interface 802 at more than one location at the same time.

[0133] When the first user and the second user touch their respective interfaces 802 at one position, the first user interface 802 displays a first indicator element 804 to indicate the position where the first user touched the first user interface 802, and displays a second indicator element 806 to indicate the position on the first user interface 802 corresponding to the position on the second user interface 802 touched by the second user.

[0134] In addition to the first indicator element 804 and the second indicator element 806, Fig.8D The first user interface 802 in FIG. 8 further includes a third indicator element 810 and a fourth indicator element 812. It can be understood that in other examples, the first user interface 802 can also include additional indicator elements.

[0135] The third indicator element 810 indicates an additional location touched on the first user interface 802 by the first user, and the fourth indicator element 812 indicates a location on the first user interface 802 that corresponds to another location touched on the second user interface 802 by the second user.

[0136] When the distance between the third indicator element 810 and the fourth indicator element 812 is below a predetermined threshold, the processor may determine that the users are synchronized in simultaneously touching another location (eg, a contact point).

[0137] In one example, when the first user and the second user are synchronized in simultaneously touching multiple locations on their respective user interfaces 802, the first user interface and the second user interface can be caused to generate an enhanced tactile feedback response and an enhanced audio feedback response. For example, the enhanced tactile feedback response can be greater than the initial tactile feedback response in terms of intensity or speed, and the enhanced audio feedback response can be enhanced in terms of complexity and volume compared to the initial audio feedback response.

[0138] In the example where the audio feedback response is a song, as the user establishes more contact points, additional instruments or parts may be added to the song to generate an enhanced audio feedback response.

[0139] Fig. 9 An example of a communication interface being displayed on the first user interface 902 of the first client device 102 is shown according to an example implementation. Fig. 9 In the present invention, the communication session is an electronic messaging communication session.

[0140] like Fig. 9As shown in , the user interface 902 includes an electronic message display portion 904 and a tactile portion 906. The electronic message display portion 904 includes an electronic message input by a first user on a first client device 102 or received by the first client device 102 from a second client device 102. The processor of the system 500 (e.g., a processor in the messaging server system 108 or the client device 102) receives the content of the electronic message from the first client device 102 or the second client device 102. For example, the electronic message can be input by the first user via the user interface 902 of the first client device. Alternatively, the electronic message can be input by the second user via the user interface 902 of the second client device 102. In one embodiment, the first user of the first client device 102 and the second user of the second client device 102 are online during the communication session. The users online in the communication session have a communication interface actively displayed on their respective client devices 102. These existing users are respectively able to view the message being displayed on the communication interface and input the content of the electronic message on the communication interface. In one embodiment, the content of the electronic message can include UNICODE characters or text. The electronic message may include emoticons / icons defined by the UNICODE standard. In one embodiment, the content of the electronic message may include an image, a custom graphic (e.g., an avatar), or a video. As used herein, an "electronic message" may refer to any message in electronic form, such as an email, a short message service (SMS) message, a multimedia message service (MMS) message, an instant message (IM), an Internet relay chat (IRC) message, and any other form of real-time, near real-time, synchronous, or asynchronous electronic message transceiving format.

[0141] In one embodiment, the first user may also transmit a media content item (eg, a picture or a video) via the user interface 902. Fig. 9 As shown in , a confirmation element 914 is displayed in the electronic message display portion 904 corresponding to the media content item delivered to the second user. Fig. 9 As shown in , selectable element 916 can be displayed in electronic message display portion 904 to indicate to the first user that a media content item is received from a second user. When selectable element 916 is activated via first user interface 902, the processor can cause the received media content item to be displayed by first client device 102.

[0142] The user interface 902 also includes a chat status bar 912, which includes status indicators associated with users of the client devices, respectively. In one embodiment, when the user is online in the communication session, the avatar associated with the user can be displayed in the chat status bar 912 as the user's status indicator. Specifically, when the first user is online in the communication session, the status indicator of the first user in the chat status bar 912 included in the user interface 902 displayed on the second client device 102 includes the avatar of the first user. Similarly, when the second user is online in the communication session, the status indicator of the second user in the chat status bar 912 included in the user interface 902 displayed on the first client device 102 includes the avatar of the second user.

[0143] The tactile portion 906 of user interface 902 is a zone for the first user and the second user to touch and receive tactile feedback response and audio feedback response.Tactile feedback response and audio feedback response can be based on the user touch input on its respective client device 102 synchronously in time and position.The change intensity (or strength) or the speed of the tactile feedback reaction generated also guides the user to the position on the screen that other users are touching.Similarly, the complexity, volume or pitch of the audio feedback reaction generated also can guide the user to the position on the screen that other users are touching.

[0144] In one example, a processor in system 500 detects a first touch input on first user interface 902 and a second touch input on second user interface 902. The processor may monitor a location of the first touch input on first user interface 902 and a location of the second touch input on second user interface 902.

[0145] Similar to Fig. 8A , Figure 8B , Figure 8C as well as Fig.8D ,exist Fig. 9 , the communication interface displayed on the first user interface 902 may include a first indicator element 908 and a second indicator element 910. The processor may cause the first user interface 902 to display the first indicator element 908 at the location of the first touch input, and to display the second indicator element 910 at a location on the first user interface 902 corresponding to the location of the second touch input on the second user interface 902. Similarly, the processor may cause the second user interface 902 to display the first indicator element 908 at the location of the second touch input, and to display the second indicator element 910 at a location on the second user interface 902 corresponding to the location of the first touch input on the first user interface 902.

[0146] The processor may determine a distance between a location of the first touch input on the first user interface 902 (e.g., the location of the first indicator element 908) and a location on the first user interface 902 corresponding to a location of the second touch input on the second user interface 902 (e.g., the location of the second indicator element 910). The processor may cause the first user interface 902 and the second user interface 902 to generate a tactile feedback response and an audio feedback response based on the distance.

[0147] Although the described flow chart can show the operation as a sequential process, many operations in the operation can be performed in parallel or concurrently. In addition, the order of the operations can be rearranged. The process is terminated when the operation of the process is completed. The process can correspond to a method, a program, an algorithm, etc. The operation of the method can be performed in whole or in part, can be performed in combination with some or all of the operations in other methods, and can be performed by any number of different systems (such as the system described herein, or any part thereof (such as a processor included in any one of the systems)).

[0148] Generate haptic and audio feedback responses on real-time communication interfaces

[0149] Fig.10 A process 1000 of generating tactile feedback responses and audio feedback responses on a real-time communication interface according to some examples is shown. In one example, a processor in system 500, a processor in client device 102, a processor in messaging server system 108, or any combination thereof can perform the operations in process 1000.

[0150] In operation 1002, the processor causes a communication interface of a communication session to be displayed on a first user interface of a first client device and on a second user interface of a second client device. The communication session is between a plurality of client devices including the first client device and the second client device. In one example, a first user of the first client device and a second user of the second client device are online in the communication session. The communication session may be, for example, a real-time video communication session.

[0151] In operation 1004 , the processor detects a first touch input on the first user interface and a second touch input on the second user interface.

[0152] In operation 1006, the processor monitors the position of the first touch input on the first user interface and the position of the second touch input on the second user interface. For example, the first user can touch the first user interface as the touch screen display of the first client device 102, and the second user can touch the second user interface as the touch screen display of the second client device 102.

[0153] In operation 1008, the processor determines a distance between a location of the first touch input on the first user interface and a location on the first user interface corresponding to a location of the second touch input on the second user interface. Fig.8D As shown, the processor may determine a first distance between the first indicator element 804 and the second indicator element 806 .

[0154] In operation 1010 , in response to determining that the first distance is below a predetermined threshold, the processor causes the first user interface and the second user interface to generate an initial tactile feedback response and an initial audio feedback response.

[0155] like Fig. 8A , Figure 8B , Figure 8C and Fig.8D As shown, the processor may cause the first user interface 802 to display a first indicator element 804 at the location of the first touch input, and to display a second indicator element 806 at a location on the first user interface 802 corresponding to the location of the second touch input on the second user interface 802. The processor may similarly cause the second user interface 802 to display the first indicator element 804 at the location of the second touch input, and to display a second indicator element 806 at a location on the second user interface 802 corresponding to the location of the first touch input on the first user interface 802.

[0156] In one example, the processor may also detect a third touch input on the first user interface and a fourth touch input on the second user interface. The processor may monitor the position of the third touch input on the first user interface and the position of the fourth touch input on the second user interface. Similarly, the processor determines a second distance between the position of the third touch input on the first user interface and the position on the first user interface corresponding to the position of the fourth touch input on the second user interface. Fig.8D As shown, the processor may cause the third indicator element 810 and the fourth indicator element 812 to be displayed on the first user interface 802 , and determine a second distance between the third indicator element 810 and the fourth indicator element 812 .

[0157] In response to determining that the second distance is below a predetermined threshold, the processor causes the first user interface and the second user interface to generate an enhanced tactile feedback response and an enhanced audio feedback response. For example, the enhanced tactile feedback response is greater than the initial tactile feedback response in intensity or speed, and the enhanced audio feedback response is greater than the initial audio feedback response in complexity and volume.

[0158] The initial audio feedback response and the enhanced audio feedback response may include music. For example, the initial audio feedback response may be the first part of a song, and the enhanced audio feedback response may be the second part of the song. The first part and the second part may be a continuous segment of the song. The first part and the second part may also be different layers of the same segment of the song. The different layers may be different musical parts with different instruments or different beats.

[0159] The initial tactile feedback response may include a first vibration pattern, and the enhanced tactile feedback response may include a second vibration pattern different from the first vibration pattern. In one example, in response to determining that the second distance is below a predetermined threshold, the processor causes the first user interface and the second user interface to generate an enhancement for the communication interface. The enhancement may include an overlay, a visual effect, an animation, a sound effect, or any combination thereof. The enhancement may be temporarily generated for a predetermined period of time. Figure 8C An example of enhancement 808 is shown.

[0160] Machine Architecture

[0161] Fig.11The 1100 is a diagrammatic representation of a machine 1100 within which instructions 1110 (e.g., software, programs, applications, applet, app, or other executable code) may be executed for causing the machine 1100 to perform any one or more of the methods discussed herein. For example, the instructions 1110 may cause the machine 1100 to perform any one or more of the methods described herein. The instructions 1110 convert a general purpose, unprogrammed machine 1100 into a specific machine 1100 that is programmed to perform the functions described and illustrated in the manner described. The machine 1100 may operate as a standalone device or may be coupled (e.g., networked) to other machines. In a networked deployment, the machine 1100 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 1100 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 1110 specifying actions to be taken by the machine 1100. In addition, although only a single machine 1100 is shown, the term "machine" should also be taken to include a collection of machines that individually or jointly execute instructions 1110 to perform any one or more of the methods discussed herein. For example, the machine 1100 may include any of the client device 102 or a plurality of server devices that form part of the messaging server system 108. In some examples, the machine 1100 may also include both a client system and a server system, wherein certain operations of a particular method or algorithm are performed on the server side and certain operations of the particular method or algorithm are performed on the client side.

[0162] The machine 1100 may include a processor 1104, a memory 1106, and an input / output (I / O) component 1102 that may be configured to communicate with each other via a bus 1140. In an example, the processor 1104 (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 1108 that executes instructions 1110 and a processor 1112. The term "processor" is intended to include multi-core processors, which may include two or more independent processors (sometimes referred to as "cores") that may execute instructions simultaneously. Although Fig.11 Multiple processors 1104 are shown, but the machine 1100 may include a single processor with a single core, a single processor with multiple cores (e.g., a multi-core processor), multiple processors with single cores, multiple processors with multiple cores, or any combination thereof.

[0163] The memory 1106 includes a main memory 1114, a static memory 1116, and a storage unit 1118, all of which are accessible by the processor 1104 via a bus 1140. The main memory 1106, the static memory 1116, and the storage unit 1118 store instructions 1110 that implement any one or more of the methods or functions described herein. The instructions 1110 may also reside, completely or partially, within the main memory 1114, within the static memory 1116, within the machine-readable medium 1120 within the storage unit 1118, within at least one of the processors 1104 (e.g., within a cache memory of a processor), or within any suitable combination thereof during execution thereof by the machine 1100.

[0164] The I / O components 1102 may include various components for receiving input, providing output, generating output, sending information, exchanging information, capturing measurements, etc. The specific I / O components 1102 included in a particular machine will depend on the type of machine. For example, a portable machine such as a mobile phone may include a touch input device or other such input mechanism, while a headless server machine will be less likely to include such a touch input device. It should be appreciated that the I / O components 1102 may include Fig.111102. In various examples, the I / O components 1102 may include a user output component 1126 and a user input component 1128. The user output component 1126 may include a visual component (e.g., a display such as a plasma display panel (PDP), a light emitting diode (LED) display, a liquid crystal display (LCD), a projector, or a cathode ray tube (CRT)), an acoustic component (e.g., a speaker), a tactile component (e.g., a vibration motor, a resistance mechanism), other signal generators, etc. The user input component 1128 may include an alphanumeric input component (e.g., a keyboard, a touch screen configured to receive alphanumeric input, an optical keyboard, or other alphanumeric input component), a point-based input component (e.g., a mouse, a touch pad, a trackball, a joystick, a motion sensor, or other pointing instrument), a tactile input component (e.g., a physical button, a touch screen or other tactile input component that provides the location and force of a touch or touch gesture), an audio input component (e.g., a microphone), etc.

[0165] In other examples, the I / O component 1102 may include a biometric component 1130, a motion component 1132, an environmental component 1134, or a position component 1136, as well as a wide range of other components. For example, the biometric component 1130 includes components for detecting expressions (e.g., hand expressions, facial expressions, voice expressions, body postures, or eye tracking), measuring biosignals (e.g., blood pressure, heart rate, body temperature, sweat, or brain waves), identifying people (e.g., voice recognition, retinal recognition, facial recognition, fingerprint recognition, or EEG-based recognition), etc. The motion component 1132 includes an acceleration sensor component (e.g., an accelerometer), a gravity sensor component, and a rotation sensor component (e.g., a gyroscope).

[0166] Environmental components 1134 include, for example, one or more cameras (with still image / photo and video capabilities), lighting sensor components (e.g., photometers), temperature sensor components (e.g., one or more thermometers that detect ambient temperature), humidity sensor components, pressure sensor components (e.g., barometers), acoustic sensor components (e.g., one or more microphones that detect background noise), proximity sensor components (e.g., infrared sensors that detect nearby objects), gas sensors (e.g., gas detection sensors for detecting concentrations of hazardous gases for safety purposes or for measuring pollutants in the atmosphere), or other components that can provide indications, measurements, or signals corresponding to the surrounding physical environment.

[0167] With respect to cameras, client device 102 may have a camera system including, for example, a front-facing camera on a front surface of client device 102 and a rear-facing camera on a rear surface of client device 102. The front-facing camera may, for example, be used to capture still images and videos of a user of client device 102 (e.g., a "selfie"), which may then be enhanced with the enhancement data (e.g., filters) described above. For example, the rear-facing camera may be used to capture still images and videos in a more conventional camera mode, which images are similarly enhanced with the enhancement data. In addition to the front-facing camera and the rear-facing camera, client device 102 may also include a 360° camera for capturing 360° photos and videos.

[0168] Additionally, the camera system of the client device 102 may include dual rear cameras (e.g., a main camera and a depth sensing camera), or even triple, quad, or quintuple rear camera configurations on the front and back sides of the client device 102. For example, these multi-camera systems may include a wide-angle camera, an ultra-wide-angle camera, a telephoto camera, a macro camera, and a depth sensor.

[0169] The location component 1136 includes a positioning sensor component (e.g., a GPS receiver component), an altitude sensor component (e.g., an altimeter or barometer that detects air pressure, from which the altitude can be obtained), an orientation sensor component (e.g., a magnetometer), and the like.

[0170] Various technologies may be used to implement communications. The I / O components 1102 also include a communications component 1138 that is operable to couple the machine 1100 to the network 1122 or device 1124 via a corresponding coupling or connection. For example, the communications component 1138 may include a network interface component or another suitable device that interfaces with the network 1122. In other examples, the communications component 1138 may include a wired communications component, a wireless communications component, a cellular communications component, a near field communications (NFC) component, Components (e.g. Low energy consumption), Components, and other communication components for providing communication via other forms. Device 1124 can be another machine or any peripheral device among various peripheral devices (e.g., a peripheral device coupled via USB).

[0171] In addition, the communication component 1138 can detect the identifier, or include a component that is operable to detect the identifier. For example, the communication component 1138 may include a radio frequency identification (RFID) tag reader component, an NFC smart tag detection component, an optical reader component (e.g., an optical sensor for detecting one-dimensional bar codes such as universal product codes (UPC) bar codes, multi-dimensional bar codes such as quick response (QR) codes, Aztec codes, data matrix, data symbols (Dataglyph), MaxiCode, PDF417, Ultra Code, UCC RSS-2D bar codes and other optical codes) or an acoustic detection component (e.g., a microphone for identifying an audio signal of a tag). In addition, various information can be obtained via the communication component 1138, such as obtaining positioning via Internet Protocol (IP) geolocation, obtaining location information ... Positioning is obtained through signal triangulation, positioning is obtained via detection of NFC beacon signals that can indicate a specific position, etc.

[0172] Various memories (e.g., main memory 1114, static memory 1116, and memory of processor 1104) and storage unit 1118 may store one or more sets of instructions and data structures (e.g., software) implemented or used by any one or more of the methods or functions described herein. These instructions (e.g., instructions 1110) when executed by processor 1104 cause various operations to implement the disclosed examples.

[0173] The instructions 1110 may be sent or received via a network interface device (e.g., a network interface component included in the communication component 1138) using a transmission medium and using any of several well-known transmission protocols (e.g., Hypertext Transfer Protocol (HTTP)) over the network 1122. Similarly, the instructions 1110 may be sent or received via a coupling (e.g., a peer-to-peer coupling) with the device 1124 using a transmission medium.

[0174] Software Architecture

[0175] Fig.121200 is a block diagram illustrating a software architecture 1204 that may be installed on any one or more of the devices described herein. The software architecture 1204 is supported by hardware such as a machine 1202 including a processor 1220, a memory 1226, and an I / O component 1238. In this example, the software architecture 1204 may be conceptualized as a stack of layers, where each layer provides specific functionality. The software architecture 1204 includes layers such as an operating system 1212, a library 1210, a framework 1208, and an application 1206. In operation, the application 1206 invokes an API call 1250 through the software stack and receives a message 1252 in response to the API call 1250.

[0176] The operating system 1212 manages hardware resources and provides public services. The operating system 1212 includes, for example, a kernel 1214, a service 1216, and a driver 1222. The kernel 1214 acts as an abstraction layer between the hardware layer and other software layers. For example, the kernel 1214 provides memory management, processor management (e.g., scheduling), component management, networking and security settings, and other functions. The service 1216 can provide other public services to other software layers. The driver 1222 is responsible for controlling or interfacing with the underlying hardware. For example, the driver 1222 may include a display driver, a camera driver, or Low-power drivers, Flash drivers, Serial communication drivers (e.g., USB drivers), Drivers, audio drivers, power management drivers, etc.

[0177] The libraries 1210 provide a common low-level infrastructure used by the applications 1206. The libraries 1210 may include a system library 1218 (e.g., a C standard library) that provides functions such as memory allocation functions, string manipulation functions, mathematical functions, etc. In addition, the libraries 1210 may include an API library 1224, such as a media library (e.g., a library for supporting presentation and manipulation of various media formats, such as Moving Picture Experts Group-4 (MPEG4), Advanced Video Coding (H.264 or AVC), Moving Picture Experts Group Layer-3 (MP3), Advanced Audio Coding (AAC), Adaptive Multi-Rate (AMR) audio codec, Joint Photographic Experts Group (JPEG or JPG), or Portable Network Graphics (PNG)), a graphics library (e.g., an OpenGL framework for presentation in two dimensions (2D) and three dimensions (3D) in graphics content on a display), a database library (e.g., SQLite providing various relational database functions), a web library (e.g., WebKit providing web browsing functions), etc. The library 1210 may also include various other libraries 1228 to provide many other APIs to the application 1206 .

[0178] The framework 1208 provides a common high-level infrastructure used by the applications 1206. For example, the framework 1208 provides various graphical user interface (GUI) functions, high-level resource management, and high-level positioning services. The framework 1208 can provide a wide range of other APIs that can be used by the applications 1206, some of which can be specific to a particular operating system or platform.

[0179] In an example, applications 1206 may include a home application 1236, a contacts application 1230, a browser application 1232, a book reader application 1234, a positioning application 1242, a media application 1244, a messaging application 1246, a game application 1248, and a variety of other applications such as third-party applications 1240. Applications 1206 are programs that execute functions defined in the program. Various programming languages ​​may be used to create one or more of the applications 1206 constructed in various ways, such as an object-oriented programming language (e.g., Objective-C, Java, or C++) or a procedural programming language (e.g., C language or assembly language). In a specific example, third-party applications 1240 (e.g., those created by an entity other than the vendor of a particular platform using ANDROID TM or IOS TM Software Development Kit (SDK) can be used to develop applications on platforms such as IOS TM ANDROID TM , Mobile software running on the mobile operating system of the phone or another mobile operating system. In this example, third-party applications 1240 can activate API calls 1250 provided by the operating system 1212 to facilitate the functions described herein.

[0180] System with head mounted device

[0189] like Fig.13 As shown in , the high-speed circuit 1316 includes a high-speed processor 1318, a memory 1320, and a high-speed wireless circuit 1322. In an example, the image display driver 1306 is coupled to the high-speed circuit 1316 and operated by the high-speed processor 1318 to drive the left image display and the right image display of the image display of the optical assembly 1302. The high-speed processor 1318 can be any processor capable of managing high-speed communications and the operation of any general computing system required by the head-mounted device 700. The high-speed processor 1318 includes the processing resources required to manage high-speed data transmission on the high-speed wireless connection 1334 to the wireless local area network (WLAN) using the high-speed wireless circuit 1322. In some examples, the high-speed processor 1318 executes an operating system (such as a LINUX operating system or other such operating system of the head-mounted device 700), and the operating system is stored in the memory 1320 for execution. In addition to any other duties, the high-speed processor 1318, which executes the software architecture of the head-mounted device 700, manages data transmission with the high-speed wireless circuit 1322.

Although the memory 1320 is shown as being integrated with the high-speed circuit 1316, in other examples, the memory 1320 can be a separate, individual element of the head mounted device 700. In some such examples, circuit routing can provide a connection from the image processor 1308 or the low-power processor 1326 to the memory 1320 through a chip including the high-speed processor 1318. In other examples, the high-speed processor 1318 can manage the addressing of the memory 1320 so that the low-power processor 1326 will start the high-speed processor 1318 any time a read or write operation involving the memory 1320 is needed.

[0192] like Fig.13 As shown in the figure, the low-power processor 1326 or the high-speed processor 1318 of the head-mounted device 700 can be coupled to a camera device (a visible light camera device 1310; an infrared transmitter 1312, or an infrared camera device 1314), an image display driver 1306, a user input device 1304 (for example, a touch sensor or a button), and a memory 1320.

[0200] Glossary

[0201] "Carrier signal" refers to any intangible medium that can store, encode or carry instructions for execution by a machine and includes digital or analog communications signals or other intangible media to facilitate communication of such instructions. Instructions may be sent or received over a network using a transmission medium via a network interface device.

[0202] "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.

[0203] "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.

[0204] "Component" refers to a device, physical entity or logic with the following boundaries: the boundaries are defined by function or subroutine calls, branch points, APIs or other technologies that provide partitioning or modularization for specific processing or control functions. Components can be combined with other components via their interfaces to perform machine processing. Components can be packaged functional hardware units designed for use with other components and can be part of a program that generally performs specific functions in related functions. Components can constitute software components (e.g., codes embodied on machine-readable media) or hardware components. "Hardware components" are tangible units that can perform certain operations and can be configured or arranged in a certain physical manner. In various examples, one or more computer systems (e.g., independent computer systems, client computer systems, or server computer systems) or one or more hardware components (e.g., processors or processor groups) of a computer system can be configured by software (e.g., applications or application parts) to operate to perform certain operations as described herein. Hardware components can also be implemented mechanically, electronically, or in any suitable combination thereof. For example, a hardware component may include a dedicated circuit system or logic that is permanently configured to perform certain operations. The hardware component may be a dedicated processor, such as a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC). The hardware component may also include a programmable logic or circuit system that is temporarily configured to perform certain operations by software. For example, the hardware component may include software executed by a general-purpose processor or other programmable processor. Once configured by such software, the hardware component becomes a specific machine (or a specific component of a machine) that is uniquely customized to perform the configured function and is no longer a general-purpose processor. It should be recognized that it can be determined for cost and time considerations whether to mechanically implement the hardware component in a dedicated and permanently configured circuit system or in a temporarily configured (e.g., configured by software) circuit system to implement the hardware component. 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. The software configures a specific one or more processors accordingly, for example, to 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. Therefore, 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 realized by (for example, by appropriate circuits and buses) transmitting signals between or among two or more hardware components in these hardware components. In examples where multiple hardware components are configured or instantiated at different times, communication between such hardware components can be realized, for example, by storing information in a memory structure accessible to multiple hardware components and retrieving information in the memory structure. For example, a hardware component can perform an operation, and the output of the operation is stored in a memory device coupled to it 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 temporarily configured or permanently configured, such a processor can constitute a processor-implemented component that operates to perform one or more operations or functions described herein. As used herein, "processor-implemented components" refer to hardware components implemented using one or more processors. Similarly, the method described 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 components implemented by the processor. In addition, one or more processors can also operate to support the execution of related operations in a "cloud computing" environment or as a "software as a service" (SaaS) operation. For example, at least some operations in the operation can be performed by a computer group (as an example of a machine including a processor), wherein these operations can be accessed via a network (for example, the Internet) and via one or more appropriate interfaces (for example, API). The execution of certain operations can be distributed between processors, not only resident in a single machine, but also deployed across multiple machines. In some examples, a processor or a component implemented by a processor can be located in a single geographic location (for example, in a home environment, an office environment, or a server cluster). In other examples, a processor or a component implemented by a processor can be distributed across multiple geographic locations.

[0205] "Computer-readable storage media" refers to both machine storage media and transmission media. Therefore, these terms include both storage devices / medium 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.

[0206] "Ephemeral messages" are messages that can be accessed for a limited duration of time. Ephemeral messages can be text, images, videos, etc. The access time of 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 ephemeral.

[0207] "Machine storage media" refers to a single or multiple storage devices and media (e.g., centralized or distributed databases, and associated caches and servers) that store executable instructions, routines, and data. Thus, the term should be considered to include, but is not limited to, solid-state memory and optical and magnetic media, including memory internal or external to the processor. Specific examples of machine storage media, computer storage media, and device storage media include: non-volatile memory, including, for example, semiconductor memory devices such as erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), FPGA, and flash memory devices; magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks. The terms "machine storage media", "device storage media", and "computer storage media" mean the same thing and may be used interchangeably in this disclosure. The terms "machine storage media", "computer storage media", and "device storage media" expressly exclude carrier waves, modulated data signals, and other such media, at least some of which are covered by the term "signal media".

[0208] “Non-transitory computer-readable storage medium” refers to tangible media capable of storing, encoding, or carrying instructions to be executed by a machine.

[0209] "Signal medium" refers to any intangible medium that can store, encode or carry instructions executed by a machine and includes digital or analog communication signals or other intangible media that facilitate the communication of software or data. The term "signal medium" should be deemed to include any form of modulated data signals, carrier waves, etc. The term "modulated data signal" means a signal in which one or more of its characteristics is set or changed in such a manner as to encode information in the signal. The terms "transmission medium" and "signal medium" mean the same thing and may be used interchangeably in this disclosure.
