The present disclosure relates generally to application features in messaging applications.
As consumption of content on mobile devices continues to grow, application developers seek new ways to engage users. Application developers constantly release new versions of their applications that have additional features to keep their users interested. Application developers, though, often fail to consider the capabilities of the hardware devices used to run the applications, which can negatively impact the new application releases.
In the drawings, which are not necessarily drawn to scale, like numerals may describe similar components in different views. To easily identify the discussion of any particular element or act, the most significant digit or digits in a reference number refer to the figure number in which that element is first introduced. Some embodiments are illustrated by way of example, and not limitation, in the figures of the accompanying drawings.
The description that follows includes systems, methods, techniques, instruction sequences, and computing machine program products that embody illustrative embodiments of the disclosure. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide an understanding of various embodiments. It will be evident, however, to those skilled in the art, that embodiments may be practiced without these specific details. In general, well-known instruction instances, protocols, structures, and techniques are not necessarily shown in detail.
Typically, application developers release new versions of their applications to add, remove, or modify features of their applications. However, in developing new versions of the applications, the application developers do not always consider the impact of the features on the underlying hardware. Specifically, features added to new application versions grow in complexity at a faster rate than the hardware capabilities of the devices on which the applications run. As a result, when the new versions of the applications are released, the devices running the new versions can often experience severe lag and over-consumption of resources, such as faster battery drain. This not only negatively impacts how the new version of the application runs on the device but also negatively impacts other applications that are running on the device. This results in a poor user experience and unnecessary waste of resources.
The disclosed embodiments improve the efficiency and functioning of client-side electronic devices by automatically and selectively scaling a given application feature based on resources of respective devices, e.g., based on determining whether device resources consumed by the feature exceed the underlying capabilities of a device. In particular, the feature is dynamically scalable responsive to changes in one or more device properties. Specifically, the disclosed embodiments provide a messaging application comprising a feature to a client device. The feature of the messaging application has a plurality of selectable or alternative complexity levels. Such complexity levels provide different functionalities for the feature and consume different amounts of resources. The disclosed embodiments access a first configuration rule of a plurality of configuration rules that associates a first device property rule with the feature of the messaging application. The disclosed embodiments determine that the first configuration rule is satisfied by a first property of the client device and, in response, cause the feature to operate on the client device at a first complexity level of the plurality of selectable complexity levels that is greater than a second complexity level of the plurality of selectable complexity levels.
In this way, features of the messaging application that do not satisfy configuration rules associated with the features, thereby indicating that the features exceed or unduly tax capabilities of the device, operate at lower complexities or complexities that the device is better equipped to handle. Such automated scaling of client-side feature complexity prevents the need to disable the features in their entireties, allowing the user to still enjoy the functions of the features in different ways depending on the capabilities of their devices. This increases the efficiency of running the messaging application on the device without wasting resources or degrading the overall user experience. In particular, rather than avoiding launching or running the feature of the messaging application on the device, such as because it has resource requirements that exceed the capabilities of the device, those features with complexity levels whose resource requirements or computational loads exceed the capabilities or capacity of the device are scaled down to operate at lower complexity levels whose resource requirements or computational loads do not exceed the capabilities or capacity of the device. This allows the messaging application to run on the device without overly burdening the memory, bandwidth, and processing resources of the device.
Accordingly, each messaging client application 104 is able to communicate and exchange data with another messaging client application 104 and with the messaging server system 108 via the network 106. The data exchanged between messaging client applications 104 and between a messaging client application 104 and the messaging server system 108 includes functions (e.g., commands to invoke functions) as well as payload data (e.g., text, audio, video, or other multimedia data).
The messaging client application 104 includes multiple features, one or more of which are scalable, by which is meant that such a feature is operable in a plurality of different alternative complexity levels. For example, the messaging client application 104 can include a scalable maps-based graphical user interface (GUI) feature that allows a user to see where his/her contacts or friends are geographically located in a graphical map-based interface. The messaging client application 104 can include a scalable messaging feature allowing a user to exchange messages with one or more friends. The messaging client application 104 can include a scalable games feature allowing a user to play games via the messaging client application 104 with one or more friends on the messaging client application 104. The messaging client application 104 can include a scalable memories feature in which images and videos captured by the user using a camera-enabled device running the messaging client application 104 are stored. The messaging client application 104 can include a scalable discover feature allowing the user to access a GUI in which content, such as videos and images, that other users of the messaging client application 104, which are friends or not friends of the user, captured, submitted, and posted. The messaging client application 104 can include a scalable friends feed feature which shows a user a chronologically-arranged list of status updates, images, videos, and content generated and associated with the user's friends. The messaging client application 104 can include a scalable image recognition feature that processes a real-time or stored video or image to identify and recognize objects depicted in the video or image.
The messaging client application 104 can include a scalable avatar feature which allows a user to create an animated avatar representation of the user to be shared with the user's friends and to view avatar representations of the user's friends on the messaging client application 104 in any of the GUIs of the messaging client application 104, such as in the map-based GUI. The messaging client application 104 can include a scalable lens feature allowing the user to overlay two-dimensional (2D) or three-dimensional (3D) graphical virtual objects (such as filters or geographically-relevant content) onto a scene depicted in real-time or stored images or videos that are/were captured by a camera-enabled device running the messaging client application 104. The messaging client application 104 can include a scalable video encoding or decoding feature allowing a user device to capture and store a video in one or more formats and/or transcode a previously captured video. The messaging client application 104 can include a scalable encryption feature allowing a user to encrypt/decrypt messages or content exchanged using the messaging client application 104 with one or more other users. The messaging client application 104 can include a scalable backup feature which automatically stores copies, on a server, of content the messaging client application 104 captured using the device running the messaging client application 104.
Any one or combination of these and other features discussed above and below of the messaging client application 104 may be installed and integrated in the messaging client application 104 to operate at a predetermined complexity level (e.g., the lowest complexity level) when the messaging client application 104 is initially downloaded and installed on the client device 102. In an embodiment, certain ones of the scalable features of the messaging client application 104, even though they are installed with the messaging client application 104 on the client device 102, are set to operate at the lowest complexity level by default. This means that when the messaging client application 104 runs or is launched and executed on the client device 102, the features operate at the lowest complexity level, thereby having minimal resource requirements or computational loads that do not exceed the capabilities or capacity of the device. In such cases, options to access enhancements (e.g., animations, different sets of graphical elements for overlaying a real-time video feed, and so forth) associated with higher complexity levels of the features (having greater resource requirements or computational loads that may end up exceeding the capabilities or capacity of the device) are prevented from being displayed or made available in any GUI of the messaging client application 104.
In some implementations, the messaging client application 104 can scale up the scalable feature that is by default set to operate at a low complexity level. In such cases, after the feature is scaled up, the messaging client application 104 runs the feature at the higher complexity level and presents an option to a user in a GUI allowing the user to access the enhancements of the feature. In some embodiments, in cases where a particular feature is selected or configured to operate at the lowest complexity level by default, when any of multiple configuration rules that are associated with the particular feature match or are satisfied by properties of the client device 102 and/or the user of the client device 102, an automatic feature scaling system 124 uses a prioritization or ranking technique to select one of the multiple configuration rules to override the default disabled state of the particular feature.
In some embodiments, the messaging client application 104 is downloaded and installed on the client device 102 only with those features that are set to operate at the lowest alternative or selectable complexity level by default. When a feature is requested or is needed to be operated at a higher complexity level at some later point in time, the feature is scaled up to operate at the higher complexity level, such as by downloading additional operations and functions implementing the higher complexity level from the server, and integrated into the messaging client application 104. For example, the messaging client application 104 may be downloaded and installed with code for its various features to operate at the lowest alternative or selectable complexity level. At some later point, a given one of the features of the messaging application can be scaled up by downloading code for operating the feature at the higher complexity level to supplement and/or replace the previously installed code for operating the feature at the lowest alternative or selectable complexity level. In alternate embodiments, code for operating the feature at all of the alternative complexity levels is downloaded and installed with the installation of the messaging client application 104. In such cases, the messaging client application 104 is instructed to select only one of the code segments to operate the feature at a given alternative complexity level.
Any one or combination of these and other scalable features discussed above and below of the messaging client application 104 may operate on the client device 102 at one or more different selectable or alternative complexity levels. Each complexity level allows the feature to provide a particular functionality with certain different enhancements. For example, a scalable maps-based GUI feature operating at a first complexity level that is greater than (e.g., being more complex than and/or consuming greater on-device resource capacities during implementation) a second complexity level may provide avatars or animations associated with various user representations on the GUI. However, when the scalable maps-based GUI feature operates at the second, lower complexity level, those same users are represented with text and not avatars or animations.
As referred to herein, “complexity level” (or level of complexity) represents the relative amount of processing and device resources (e.g., network bandwidth, processor operations, memory operations, battery consumption, and so forth) consumed by a set of operations and functions that implement a given function or a feature of the messaging client application 104. The set of operations and functions that implement the given function or feature may consume more hardware and software resources of the client device 102 or less depending on the complexity level. For example, a given client device 102 may have a graphics accelerator available that drains the battery of the client device 102 very quickly. A feature operating at a high complexity level may include a set of operations and functions that use the graphics accelerator to implement the functions of the feature (e.g., to provide real-time enhancements to a video feed). The same feature operating at a lower complexity level may include a different set of operations and functions that implement the functions of the feature using a general purpose processor rather than the hardware accelerator. The same feature operating at the lower complexity level may thereby consume less of the battery resource at the cost of lower quality real-time enhancements of the video feed than were the feature to operate at the higher complexity level. Namely, operating the feature at the high complexity level may allow the feature to present a first set of graphical elements on a real-time video feed (e.g., that include animation and use gyroscopic and position sensors of the client device 102) and operating the feature at the lower complexity level may allow the feature to present a different second set of graphical elements (e.g., that include static images and do not rely on gyroscopic and position sensors of the client device 102) on the real-time video feed.
In some embodiments, the messaging client application 104 communicates with an automatic feature scaling system 124 to identify one or more features of the messaging client application 104 to enable or disable and/or to select the complexity level at which the feature is to operate. The automatic feature scaling system 124 utilizes a set of configuration rules to identify which features to enable or disable and/or to select the complexity level at which the feature is to operate. In an embodiment, the automatic feature scaling system 124 receives an identifier of the client device 102 on which the messaging client application 104 is implemented. The automatic feature scaling system 124 uses the identifier to retrieve a set of configuration rules associated with the client device 102. Specifically, the automatic feature scaling system 124 can determine one or more properties of the client device 102, such as a device type, available memory storage space, current battery level, disk level attributes, operating system version, messaging client application 104 version, processor type, or any other hardware capability of the client device 102 using the identifier. In an embodiment, the automatic feature scaling system 124 searches a database to retrieve the set of configuration rules associated with the identifier.
In an embodiment, the automatic feature scaling system 124 selects a particular feature of the messaging client application 104 that is enabled or disabled currently on the messaging client application 104 that is running or installed on the client device 102. The automatic feature scaling system 124 identifies a set of configuration rules or just one configuration rule that is associated with the particular feature. In cases where multiple configuration rules are associated with the particular feature, the automatic feature scaling system 124 uses a prioritization or ranking technique to select only one of the multiple configuration rules. Once the configuration rule is selected, the automatic feature scaling system 124 obtains one or more device property rules and/or one or more user information rules specified in the configuration rule. For example, the configuration rule can specify a particular Boolean, scalar, or complex construct expression that logically or otherwise combines the one or more device property rules and/or one or more user information rules. The automatic feature scaling system 124 evaluates whether the configuration rule is satisfied (e.g., the expression of the rule is determined to be TRUE) or not satisfied (e.g., the expression of the rule is determined to be FALSE) using device properties and/or user information of the client device 102.
In some embodiments, the messaging client application 104 communicates with the automatic feature scaling system 124 to identify and select a complexity level at which one or more features of the messaging client application 104 will operate. The automatic feature scaling system 124 utilizes a set of configuration rules to identify the complexity level of the features. In an embodiment, the automatic feature scaling system 124 receives an identifier of the client device 102 on which the messaging client application 104 is implemented. The automatic feature scaling system 124 uses the identifier to retrieve a set of configuration rules associated with the client device 102. Specifically, the automatic feature scaling system 124 can determine one or more properties of the client device 102, such as a device type, available memory storage space, current battery level, disk level attributes, operating system version, messaging client application 104 version, processor type, or any other hardware capability of the client device 102 using the identifier. In an embodiment, the automatic feature scaling system 124 searches a database to retrieve the set of configuration rules associated with the identifier. The automatic feature scaling system 124 selects a complexity level of multiple complexity levels for operating a particular feature of the messaging client application 104.
In some embodiments, the automatic feature scaling system 124 communicates a portion of the configuration rule (e.g., a given portion of the expression of the rule) to be evaluated by the client device 102. In this way, some information that is available only to the client device 102 and is not available to the automatic feature scaling system 124 but is included in the configuration rule can be used to determine if the rule is satisfied. Namely, a first portion of the configuration rule can be evaluated by the automatic feature scaling system 124 and a second portion of the same configuration rule can be evaluated by the client device 102. The client device 102 can transmit the results of the evaluation of the second portion of the configuration rule to the automatic feature scaling system 124 to be combined with the results of the evaluation of the first portion. For example, the automatic feature scaling system 124 does not have access to information such as the amount of free memory, current battery level, or the currently available bandwidth of the client device 102 but does have information indicating the processor speed and type of the client device 102. Namely, certain information about the client device 102 remains physically unchangeable and so can be stored on the automatic feature scaling system 124 for access independent of the client device 102. Other information dynamically changes throughout the life of the device, such as the currently available bandwidth or battery level, or current geographical location, and so when such information is included in the configuration rule parameters, the client device 102 needs to be involved in evaluating that portion of the configuration rule.
In some embodiments, as part of having the client device 102 evaluate a rule, the automatic feature scaling system 124 transmits a benchmark associated with the rule that represents functionality of the feature associated with the rule. The client device 102 can run the benchmark by executing code included in the benchmark and provide performance results to the automatic feature scaling system 124 of how the client device 102 ran the benchmark. The automatic feature scaling system 124 can then use the performance results to evaluate parameters of the configuration rule. This way, before a feature of the messaging client application 104 is enabled on the client device 102 and operates at a particular complexity level, the benchmark representing functions of the feature can be run by the client device 102 to verify that operating the feature at a particular complexity level will run without degrading or negatively impacting the messaging client application 104 or other applications installed and running on the client device 102. Specifically, the benchmark may be designed to consume the same amount and types of processor capabilities and resources of a given device as the associated complexity level of the feature of the messaging client application 104. This allows the automatic feature scaling system 124 to test whether the processor capabilities and device resources required by the corresponding complexity level of the feature of the messaging client application 104 are available on the client device 102 using the benchmark before causing the particular feature to operate at the particular complexity level.
In an embodiment, when the automatic feature scaling system 124 determines that the configuration rule is not satisfied (e.g., because any one or combination of parameters of the expression specified by the rule is not met by or do not match the device properties and/or user information of the client device 102), the automatic feature scaling system 124 scales down the complexity level of the feature to cause the feature associated with the configuration rule to operate at a lower complexity level than the default complexity level. When the automatic feature scaling system 124 determines that the configuration rule is satisfied (e.g., the combination of parameters of the expression specified by the rule are all met by or match the device properties and/or user information of the client device 102), the automatic feature scaling system 124 maintains complexity level of the feature associated with the configuration rule at the current level and does not scale down the complexity level of the feature. In some circumstances, the automatic feature scaling system 124 transmits code segments of the selected complexity level for the particular feature that is selected to the client device 102 to update the messaging client application 104 and enable the messaging client application 104 to operate the particular feature at the selected complexity level.
In some embodiments, the configuration rules stored in the database accessible to the automatic feature scaling system 124 are dynamically updated to include new rules or to change or delete previously stored rules. Such updates are performed by providing application developers or developers of the messaging client application 104 with access, via a GUI, to the rules. The application developer can define a new configuration rule using the GUI by specifying various parameters such as a Boolean expression that logically combines one or more device property rules and/or one or more user information rules and identifies an action associated with a feature of the particular messaging client application 104 to perform when the parameters of the configuration rule are satisfied. Such an action can include enabling the feature, disabling the feature, modifying components of the feature, downloading additional code associated with the feature, prefetching video content for a particular user, scaling a feature up or down, and so forth. As referred to herein, scaling a feature up means causing the feature to operate at a higher complexity level. As referred to herein, scaling a feature down means causing the feature to operate at a lower complexity level.
The GUI may also allow the developer to assign a priority or rank to the configuration rule, which may be used by the automatic feature scaling system 124 when a given feature is associated with multiple matching configuration rules. The GUI may also allow the developer to specify a set of portions of the configuration rule to be evaluated by the automatic feature scaling system 124 and another set of portions of the configuration rule to be evaluated by the client device 102. As referred to herein, evaluating a rule means comparing current data (e.g., current device properties and/or user information) with the combination of the corresponding rule parameters to determine whether those parameters match the current data. Namely, evaluating a rule means determining whether an expression of the rule is TRUE or FALSE given the current data associated with the rule parameters.
As an example, a configuration rule includes an expression that, when satisfied, instructs the messaging client application 104 to operate at a high complexity level, which includes operations to prefetch or automatically download a set of videos or images provided by other users of the messaging client application 104. Such an expression can include a logical AND operation of a first device property rule (e.g., battery level exceeds 70), a second device property rule (e.g., the device is part of a cluster of devices that is greater than 6), and a logical OR operation of a third device property rule (e.g., bandwidth of the device is greater than 100 Mbps) and a user information rule (e.g., a user consumes more than 25 videos that were provided by other users per day). As such, in a given circumstance in which a given client device 102 has a battery level of 80 that exceeds the battery level 70 specified by the first device property rule, is part of a device cluster that exceeds 6 devices, and has a bandwidth greater than 100 Mbps or is used by a user that consumes more than 25 videos provided by other users per day, the automatic feature scaling system 124 scales up the feature of the messaging client application 104 to prefetch or automatically download a set of videos or images provided by other users of the messaging client application 104. If the rule is not satisfied, the automatic feature scaling system 124 scales down the feature of the messaging client application 104 causing the messaging client application 104 to operate at a lower complexity level in which the set of videos or images are downloaded on-demand, when needed, and/or when specifically requested by the user. This consumes less bandwidth and processing resources of the client device 102 but provides, in essence, the same functionality, albeit at a slower pace.
The messaging server system 108 provides server-side functionality via the network 106 to a particular messaging client application 104. While certain functions of the messaging system 100 are described herein as being performed either by a messaging client application 104 or by the messaging server system 108, it will be appreciated that the location of certain functionality within either the messaging client application 104 or the messaging server system 108 is a design choice. For example, it may be technically preferable to initially deploy certain technology and functionality within the messaging server system 108, but to later migrate this technology and functionality to the messaging client application 104 where a client device 102 has a sufficient processing capacity. As another example, the entire functionality or a subset of the functionality of the automatic feature scaling system 124 can be incorporated into the messaging client application 104 or other component of the client device 102.
The messaging server system 108 supports various services and operations that are provided to the messaging client application 104. Such operations include transmitting data to, receiving data from, and processing data generated by the messaging client application 104. This data may include message content, client device information, geolocation information, media annotation and overlays, virtual objects, message content persistence conditions, social network information, and live event information, as examples. Data exchanges within the messaging system 100 are invoked and controlled through functions available via user interfaces (UIs) of the messaging client application 104.
Turning now specifically to the messaging server system 108, an application programming interface (API) server 110 is coupled to, and provides a programmatic interface to, an application server 112. The application server 112 is communicatively coupled to a database server 118, which facilitates access to a database 120 in which is stored data associated with messages processed by the application server 112.
Dealing specifically with the API server 110, this server 110 receives and transmits message data (e.g., commands and message payloads) between the client device 102 and the application server 112. Specifically, the API server 110 provides a set of interfaces (e.g., routines and protocols) that can be called or queried by the messaging client application 104 in order to invoke functionality of the application server 112. The API server 110 exposes various functions supported by the application server 112, including account registration; login functionality; the sending of messages, via the application server 112, from a particular messaging client application 104 to another messaging client application 104; the sending of media files (e.g., images or video) from a messaging client application 104 to a messaging server application 114, for possible access by another messaging client application 104; the setting of a collection of media data (e.g., story); the retrieval of such collections; the retrieval of a list of friends of a user of a client device 102; the retrieval of messages and content; the adding and deleting of friends to and from a social graph; the retrieval of one or more features (e.g., executable code segments of the one or more features) of the messaging client application 104, such as features that are selected to operate at a particular selected complexity level on the messaging client application 104; the retrieval of operations and functions for different, higher or lower complexity levels of one or more features (e.g., executable code segments of the different, higher or lower complexity levels of the one or more features) of the messaging client application 104; the location of friends within a social graph; access to user conversation data; access to avatar information stored on the messaging server system 108; and the opening of an application event (e.g., relating to the messaging client application 104).
The application server 112 hosts a number of applications and subsystems, including the messaging server application 114, an image processing system 116, a social network system 122, and the automatic feature scaling system 124. The messaging server application 114 implements a number of message processing technologies and functions, particularly related to the aggregation and other processing of content (e.g., textual and multimedia content) included in messages received from multiple instances of the messaging client application 104. As will be described in further detail, the text and media content from multiple sources may be aggregated into collections of content (e.g., called stories or galleries). These collections are then made available, by the messaging server application 114, to the messaging client application 104. Other processor- and memory-intensive processing of data may also be performed server-side by the messaging server application 114, in view of the hardware requirements for such processing.
The application server 112 also includes the image processing system 116, which is dedicated to performing various image processing operations, typically with respect to images or video received within the payload of a message at the messaging server application 114.
The social network system 122 supports various social networking functions and services and makes these functions and services available to the messaging server application 114. To this end, the social network system 122 maintains and accesses an entity graph within the database 120. Examples of functions and services supported by the social network system 122 include the identification of other users of the messaging system 100 with whom a particular user has relationships or whom the particular user is “following,” and also the identification of other entities and interests of a particular user. Such other users may be referred to as the user's friends. The social network system 122 may access location information associated with each of the user's friends to determine where they live or are currently located geographically. The social network system 122 may maintain a location profile for each of the user's friends indicating the geographical location where the user's friends live.
The application server 112 is communicatively coupled to the database server 118, which facilitates access to the database 120 in which is stored data associated with messages processed by the messaging server application 114.
The database 120 includes message data stored within a message table 214. An entity table 202 stores entity data, including an entity graph 204. Entities for which records are maintained within the entity table 202 may include individuals, corporate entities, organizations, objects, places, events, and so forth. Regardless of type, any entity regarding which the messaging server system 108 stores data may be a recognized entity. Each entity is provided with a unique identifier, as well as an entity type identifier (not shown).
The entity graph 204 furthermore stores information regarding relationships and associations between entities. Such relationships may be social, professional (e.g., work at a common corporation or organization), interest-based, or activity-based, merely for example.
The message table 214 may store a collection of conversations between a user and one or more friends or entities. The message table 214 may include various attributes of each conversation, such as the list of participants, the size of the conversation (e.g., number of users and/or number of messages), the chat color of the conversation, a unique identifier for the conversation, and any other conversation-related feature(s).
The database 120 also stores annotation data, in the example form of filters, in an annotation table 212. The database 120 also stores annotated content received in the annotation table 212. Filters for which data is stored within the annotation table 212 are associated with and applied to videos (for which data is stored in a video table 210) and/or images (for which data is stored in an image table 208). Filters, in one example, are overlays that are displayed as overlaid on an image or video during presentation to a recipient user. Filters may be of various types, including user-selected filters from a gallery of filters presented to a sending user by the messaging client application 104 when the sending user is composing a message. Other types of filters include geolocation filters (also known as geo-filters), which may be presented to a sending user based on geographic location. For example, geolocation filters specific to a neighborhood or special location may be presented within a UI by the messaging client application 104, based on geolocation information determined by a Global Positioning System (GPS) unit of the client device 102. Another type of filter is a data filter, which may be selectively presented to a sending user by the messaging client application 104, based on other inputs or information gathered by the client device 102 during the message creation process. Examples of data filters include a current temperature at a specific location, a current speed at which a sending user is traveling, a battery life for a client device 102, or the current time.
Other annotation data that may be stored within the image table 208 is so-called “lens” data. A “lens” may be a real-time special effect and sound that may be added to an image or a video.
Configuration rules 207 stores a set of configuration rules associated with different features of the messaging client application 104. In some cases, multiple configuration rules 207 are associated with the same feature of the messaging client application 104. In some cases, only one configuration rule is associated with a corresponding one of the features of the messaging client application 104. The configuration rules 207 may be indexed by device type, build of the messaging client application 104, version of the messaging client application 104, geographical location, processor type, user attribute, user friends, or any other suitable device property or user information or combination of information. Rules stored in the configuration rules 207 can be accessed by any component in the system and/or by authorized devices or users. Rules can be added, modified, or deleted to/from the configuration rules 207 via a GUI presented to an application developer of the messaging client application 104. In some embodiments, configuration rules stored in the configuration rules 207 are associated with an owner (e.g., a creator of the rule) and, in such cases, the configuration rules 207 can only be modified or deleted by the associated owner using an owner identifier.
Certain rules stored in the configuration rules 207 can be selectively activated based on a time of day, device context, or other suitable attribute. Inactive rules are not used in evaluating whether a given device satisfies a rule to perform an action for a feature of the messaging client application 104. Such action may include selecting a particular complexity level for implementing the feature from multiple complexity levels.
Benchmarks 209 stores a set of benchmarks associated with different features of the messaging client application 104. In some cases, multiple benchmarks are associated with the same feature of the messaging client application 104. In some cases, only one benchmark is associated with a corresponding one of the features of the messaging client application 104. Each benchmark in benchmarks 209 simulates various processor and device operations performed by the corresponding feature of the messaging client application 104. In some cases, different benchmarks can be associated with different device types, builds of the messaging client application 104, versions of the messaging client application 104, geographical locations, processor types, user attributes, user friends, or any other suitable device property or user information or combination of information. The benchmarks 209 stores snippets of code that represent operations performed by the complexity level(s) corresponding to the feature of the messaging client application 104. In some cases, the snippets of code include simulations of only the most complex operations performed by the complexity level(s) of the feature of the messaging client application 104.
Device capabilities 220 stores a list of standard resources, processor types, memory types, and other suitable device properties of different device models and types. In some cases, each client device 102 of the messaging client application 104 may provide, upon installation of the messaging client application 104, its corresponding standard physical capabilities. Such capabilities can be stored and indexed by a device identifier associated with the client device 102. In some embodiments, the device capabilities 220 stores dynamic device properties, such as battery levels, available storage space, network type, and bandwidth for one or more client devices 102. In such cases, the dynamic device properties for a given device can be updated periodically or continuously by polling or requesting such information from the given device. In some cases, the device capabilities 220 groups various devices and their capabilities into clusters of devices of similar types by grouping the corresponding identifiers of the devices into the same cluster of devices. In some embodiments, the device capabilities 220 organizes and clusters the device capabilities 220 by friends associated with the devices such that device capabilities 220 of devices used by a given collection of friends, as indicated by the entity graph 204, is grouped together. In some embodiments, the device capabilities 220 organizes and clusters the device by geographical region associated with the devices.
User information 221 stores profiles for various users of the messaging client application 104. Such information may include how active each user is, which features of the messaging client application 104 each user frequently uses, user upload history, developer status, whether the user is a beta tester, how often a given feature of the messaging client application 104 is used by each user, a geographical location associated with each user, and any other suitable information or combination of such information. The user information 221 is updated continuously or periodically as users utilize the messaging client application 104.
As mentioned above, the video table 210 stores video data which, in one embodiment, is associated with messages for which records are maintained within the message table 214. Similarly, the image table 208 stores image data associated with messages for which message data is stored in the entity table 202. The entity table 202 may associate various annotations from the annotation table 212 with various images and videos stored in the image table 208 and the video table 210.
A story table 206 stores data regarding collections of messages and associated image, video, or audio data, which are compiled into a collection (e.g., a story or a gallery). The creation of a particular collection may be initiated by a particular user (e.g., any user for which a record is maintained in the entity table 202). A user may create a “personal story” in the form of a collection of content that has been created and sent/broadcast by that user. To this end, the UI of the messaging client application 104 may include an icon that is user-selectable to enable a sending user to add specific content to his or her personal story.
A collection may also constitute a “live story,” which is a collection of content from multiple users that is created manually, automatically, or using a combination of manual and automatic techniques. For example, a “live story” may constitute a curated stream of user-submitted content from various locations and events. Users whose client devices 102 have location services enabled and are at a common location event at a particular time may, for example, be presented with an option, via a UI of the messaging client application 104, to contribute content to a particular live story. The live story may be identified to the user by the messaging client application 104 based on his or her location. The end result is a “live story” told from a community perspective.
A further type of content collection is known as a “location story,” which enables a user whose client device 102 is located within a specific geographic location (e.g., on a college or university campus) to contribute to a particular collection. In some embodiments, a contribution to a location story may require a second degree of authentication to verify that the end user belongs to a specific organization or other entity (e.g., is a student on the university campus).
The contents (e.g., values) of the various components of the message 300 may be pointers to locations in tables within which content data values are stored. For example, an image value in the message image payload 306 may be a pointer to (or address of) a location within the image table 208. Similarly, values within the message video payload 308 may point to data stored within the video table 210, values stored within the message annotations 312 may point to data stored in the annotation table 212, values stored within the message story identifier 318 may point to data stored in the story table 206, and values stored within the message sender identifier 322 and the message receiver identifier 324 may point to user records stored within the entity table 202.
Feature selection module 411 communicates with a messaging client application 104 implemented on a given client device 102 to identify a feature of the messaging client application 104 to analyze. The feature can be a feature that is currently selected to operate at a low complexity level. In an embodiment, the feature selection module 411 cycles through a predetermined list of features over time to verify that the feature should be scaled up/down and change the selected complexity level of the feature if a given configuration rule is satisfied indicating a state change is needed. In this way, the feature is dynamically scalable responsive to changes in one or more device properties. As discussed herein, operating a feature at a given complexity level means executing a set of instructions having the given complexity level to implement the feature. For example, operating a feature at a first complexity level means executing a first set of instructions having the first complexity level to implement the feature and operating the same feature at a second complexity level means executing a second set of instructions having the second complexity level to implement the feature.
The feature selection module 411 may access user information 221 to infer user behavior and interest in having a particular feature of the messaging client application 104 scaled up to operate at a higher complexity level. For example, the user information 221 may indicate that the user has recently started using the camera of the camera-enabled device on which the messaging client application 104 is implemented to capture and share videos. The feature selection module 411 may also determine that the lens feature (e.g., a feature that utilizes object recognition and allows a user to insert 2D or 3D graphical objects) is currently set to operate at a low complexity level on the device and is a feature that is popular among the user's friends or a set of users who frequently share videos. The feature selection module 411 may, in response, communicate the selected feature to the configuration rule selection module 419 to determine whether to scale up the feature. Similarly, the feature selection module 411 may determine that the lens feature is currently scaled up and operating at a high complexity level but that the user of the device has not captured video using the camera-enabled device in more than a threshold period of time. In response, feature selection module 411 may communicate the selected feature to the configuration rule selection module 419 to determine whether to scale down the feature or perform an action associated with the feature.
As another example, the feature selection module 411 may determine that a geographical location of the user of the messaging client application 104 has changed. In response, the feature selection module 411 may identify a set of features that are location dependent and provide one or more of the identified features to the configuration rule selection module 419 to determine whether an action should be performed for such features. As another example, the feature selection module 411 receives a version identifier or client device 102 identifier and retrieves a set of features that are operating at a low complexity level on the client device 102. The feature selection module 411 provides the retrieved set of features to the configuration rule selection module 419 for analysis as to whether to scale up the features. Similarly, the feature selection module 411 receives a version identifier or client device 102 identifier and retrieves a set of features that are currently set to operate at a high complexity level on the client device 102. The selection module 411 provides the retrieved set of features to the configuration rule selection module 419 for analysis as to whether to scale down the features.
Configuration rule selection module 419 retrieves one or more configuration rules from configuration rules 207 that are associated with the features received from the feature selection module 411. The configuration rule selection module 419 determines which configuration rules, that are associated with the feature, are active and associated with the device identifier and/or user identifier. The configuration rule selection module 419 determines whether multiple such configuration rules match and are associated with the selected feature. In response, the configuration rule selection module 419 retrieves a rank associated with each rule and selects the configuration rule with the highest rank. Alternatively, or in addition, the configuration rule selection module 419 analyzes a Boolean tree associated with the expression of each configuration rule. Specifically, the configuration rule selection module 419 compares the expressions of each configuration rule that is associated with the same feature and selects the configuration rule with the longest expression.
The configuration rule selection module 419 provides the selected configuration rule to the configuration rule evaluation module 416. The configuration rule evaluation module 416 analyzes the expression contained in the selected rule to determine which parameters need to be evaluated. For example, the configuration rule evaluation module 416 identifies one or more device property rules contained in the expression and/or user information rules contained in the expression. The configuration rule evaluation module 416 also determines whether the rule specifies a particular portion of the expression that needs to be evaluated by the client device 102. The configuration rule evaluation module 416 communicates with the user information module 414 to obtain user information 221 corresponding to the user information rule and/or with the device properties module 412 to obtain device properties corresponding to the device properties rules contained in the expression.
As an example, the configuration rule includes a first device property rule (e.g., a bandwidth greater than 1 Mbps) and a second device property rule (e.g., a minimum version of the messaging client application 104). As a result, the configuration rule evaluation module 416 communicates with the device properties module 412, and provides the client device 102 identifier to the device properties module 412, to obtain the first device property (e.g., the current bandwidth of the client device 102) and the second device property (e.g., the current version of the messaging client application 104 installed on the client device 102) associated with the first and second device property rules. The device properties module 412 accesses the device capabilities 220 to retrieve the corresponding first and second device properties associated with the identifier of the client device 102. If the device capabilities 220 only has the first property and not the second property, the device properties module 412 communicates directly with the client device 102 to obtain the current value of the second property.
The configuration rule may also include a first user information rule (e.g., a beta user attribute) and a second user information rule (e.g., accesses or consumes more than 25 videos from other users per day). As a result, the configuration rule evaluation module 416 provides the user identifier to the user information module 414 to obtain the first user information (e.g., the status of the user, such as whether the user is a beta user) and the second user information (e.g., the number of videos from other users the user consumes per day). The user information module 414 retrieves the first and second user information from user information 221 and returns the information to the configuration rule evaluation module 416.
In some implementations, the configuration rule evaluation module 416 sends a portion of the expression to the client device 102 for the client device 102 to evaluate the portion of the expression. For example, the portion of the expression may specify that a particular benchmark result has to exceed a given minimum threshold performance. As a result, the configuration rule evaluation module 416 transmits the portion of the expression including the benchmark, retrieved from benchmarks 209, to the client device 102 with an instruction for the client device 102 to run the benchmark. The client device 102, after running the benchmark, may determine whether the performance exceeds the threshold indicated in the portion of the expression and provide this evaluation to the configuration rule evaluation module 416. In some implementations, the configuration rule evaluation module 416 only sends the portion of the expression to the client device 102 after verifying that another portion of the expression, evaluated at the server, is satisfied. Namely, the configuration rule evaluation module 416 evaluates the portions of the expression with the currently available information on the server and if those portions are satisfied, a remaining set of portions of the expression are sent to the client device 102 for evaluation.
In some embodiments, the configuration rule evaluation module 416 sends an instruction to the client device 102 to re-evaluate the expression at a later point in time if the expression is currently satisfied. If the expression is later no longer satisfied, the client device 102 may automatically scale down the feature or perform an action associated with the feature.
After the configuration rule evaluation module 416 obtains all of the parameters for the expression (e.g., all of the needed device properties and/or user information 221), the configuration rule evaluation module 416 determines whether the Boolean expression is satisfied. Namely, the configuration rule evaluation module 416 determines whether all or some of the received information matches the specified rules or Boolean combination of the rules.
In response to determining that the expression is satisfied, the configuration rule evaluation module 416 instructs the feature action module 418 to perform the action associated with the rule (e.g., scale the feature up, scale the feature down, enable the feature, disable the feature, or modify the feature). The feature action module 418 retrieves the action specified for the configuration rule from the configuration rules 207 and then executes the corresponding action. For example, the feature action module 418 transmits code for implementing the selected complexity level of the feature to the client device 102 to install and implement the operations and functions associated with the selected complexity level of the feature into the messaging client application 104. Alternatively, the feature action module 418 sends a message 300 to the messaging client application 104 with instructions to scale up the feature that is currently installed but operating at a low complexity level on the messaging client application 104. Alternatively, the feature action module 418 sends a message 300 to the messaging client application 104 with instructions to scale down the feature that is currently installed and operating at a high complexity level on the messaging client application 104.
As one example, a first feature that the feature selection module 411 selects includes object recognition (e.g., facial recognition that analyzes facial features of a face in an image) of an image stored on the client device 102. The object recognition feature may have multiple complexity levels, where a low complexity level utilizes a first object (facial) recognition process to implement the object recognition function and a high complexity level utilizes a second object (facial) recognition process to implement the object recognition function. The configuration rule selected by the configuration rule selection module 419 associates a plurality of device property rules including first, second, and third device property rules with the first feature. In such circumstances, a current battery level and current amount of available storage is received by the device properties module 412 from the client device 102. The configuration rule evaluation module 416 on the server determines that processing capabilities of the client device 102 exceed threshold processing capabilities indicated by the first device property rule, the current battery level exceeds a minimum battery level indicated by the second device property rule, and the current amount of available storage exceeds a minimum available storage amount indicated by the third device property rule. Prior to scaling up the first feature on the client device 102, the server instructs the client device 102 to determine whether an updated battery level of the client device 102 exceeds the minimum battery level indicated by the second device property rule and that an updated amount of available storage of the client device 102 exceeds the minimum available storage amount indicated by the third device property rule.
This way, even though a given rule is satisfied when evaluated based on a first set of device properties received by the server, the client device 102 can double check at some later point in time that after the feature associated with the given rule is scaled up, the given rule is still satisfied. Namely, the time between when the server evaluates the rule and when the client is instructed to scale up the feature may be large enough such that the battery level on the client device 102 drops below an allowable minimum. To ensure that the battery level is still above the allowable minimum after the time has passed since the server evaluated the rule, the client device 102 can test and evaluate the current battery level against the rule prior to scaling up the feature and/or while the feature is operating at a low complexity level to determine whether to scale up the feature.
As another example, a second feature that the feature selection module 411 selects includes image backup functionality for the client device 102. The configuration rule selected by the configuration rule selection module 419 may specify upload stability data and transcoding success parameters with scaling up the image backup functionality. The configuration rule evaluation module 416 retrieves information indicating upload stability data for the client device 102 and a transcoding failure rate of the client device 102 from the device properties module 412. The configuration rule evaluation module 416 determines whether the upload stability data exceeds a stability threshold indicated by the rule and that the transcoding failure rate exceeds a transcoding failure rate threshold indicated by the rule. In response to determining that the upload stability data exceeds the stability threshold and that the transcoding failure rate exceeds the transcoding failure rate threshold, the configuration rule evaluation module 416 scales up the image backup functionality for the client device 102 to backup images captured by the client device 102 in real-time rather than periodically (as when the feature is in a scaled down state), such as by instructing the feature action module 418 to scale up this feature on the client device 102.
As another example, a third feature that the feature selection module 411 selects includes a graphical eraser operation that enables a user to erase portions of an image captured by the client device 102. The configuration rule selected by the configuration rule selection module 419 may specify minimum performance capabilities a client device 102 needs to operate the graphical eraser operation feature at a high complexity level. The configuration rule evaluation module 416 retrieves information indicating a performance metric of the graphical eraser operation by executing a benchmark on the client device 102 representing operations performed by the graphical eraser operation operating at the high complexity level or retrieving a performance metric indicating how the benchmark performed on devices similar to the client device 102 in the past. The configuration rule evaluation module 416 determines that the performance metric exceeds a minimum performance threshold indicated by the first device property rule. In response to determining that the performance metric exceeds the minimum performance threshold indicated by the first device property rule, the configuration rule evaluation module 416 scales up the graphical eraser operation for the client.
As another example, a fourth feature that the feature selection module 411 selects includes a lens creation or complex lens operation (e.g., creation of a graphical element that is added to a captured image or complex operations associated with such a graphical element, such as animation, scaling, pixelation, and so forth) that enables a user to add graphical elements to images captured by the client device 102. The configuration rule selected by the configuration rule selection module 419 may specify minimum performance capabilities a client device 102 needs to operate the lens creation or complex lens operation features at a high complexity level (which provides a different set of graphical elements that are animated and utilize gyroscopic and position sensors of the client device 102 than a low complexity level).
The configuration rule evaluation module 416 retrieves information indicating a performance metric of the lens creation or complex lens operations by executing a benchmark on the client device 102 representing operations performed by the lens creation or complex lens operations or retrieving a performance metric indicating how the benchmark performed on devices similar to the client device 102 in the past. The configuration rule evaluation module 416 determines that the performance metric exceeds a minimum performance threshold indicated by the first device property rule. In response to determining that the performance metric exceeds the minimum performance threshold indicated by the first device property rule, the configuration rule evaluation module 416 scales up the lens creation or complex lens operations for the client. Namely, the lens creation operations, operating at the scaled up state implementing a high complexity level feature, allow a user to choose enhanced graphical elements that are animated and utilize gyroscopic and position sensors of the client device 102. The lens creation operations, operating at the scaled down state implementing a low complexity level feature, allow a user to choose static graphical elements that do not utilize gyroscopic and position sensors of the client device 102.
In some embodiments, the complexity level for implementing the lens feature may be selected based on whether the client device 102 includes a frame fetch buffer capability. Such capability may be a rule in the configuration rule that is evaluated against device properties of the client device 102. For example, if the client device 102 includes frame fetch buffer capability, the lens feature may be selected to operate at a high complexity level. If the client device 102 does not include frame fetch buffer capability, the lens feature may be selected to operate at a low complexity level.
In some embodiments, the complexity level for implementing encryption of messages and content on the client device may be selected based whether a configuration rule is satisfied. If the configuration rule is satisfied, a first encryption process for encrypting messaging may be selected to operate at a high complexity level. If the configuration rule is not satisfied, a second encryption process, that is less secure than the first encryption process, for encrypting messaging may be selected to operate at a low complexity level.
In some embodiments, the complexity level for the messaging client application 104 capturing images using a camera on the client device may be selected based on whether a configuration rule is satisfied. If the configuration rule is satisfied, the camera functionality of the messaging client application 104 may be selected to operate at a high complexity level to capture high resolution images. If the configuration rule is not satisfied, the camera functionality of the messaging client application 104 may be selected to operate at a low complexity level to capture low resolution images.
In some embodiments, the feature selection module 411 selects, as the complexity level of the feature, an upload size for the client device 102 that controls how large a given video or image can be that is uploaded by the client device 102. A first complexity level of the feature may correspond to enabling a 4 megabyte upload video or image file, a second complexity level of the feature may correspond to enabling a 5 megabyte upload video or image file, and a third complexity level of the feature may correspond to enabling a 2 megabyte upload video or image file. Each of the first, second, and third complexity levels of the feature may be associated with a different configuration rule. The configuration rule selection module 419 may determine whether the first complexity level of the feature is associated with a configuration rule that is satisfied before evaluating the second and third complexity levels of the feature.
In an embodiment, the first complexity level of the feature is associated with a first configuration rule that includes the following Boolean expression (application version is greater than 10 AND bandwidth available to the client device 102 is greater than 1 Mbps AND (the user is a professional user OR the messaging application installed on the client device 102 is beta build)). If the configuration rule evaluation module 416 determines that this Boolean expression of the first configuration rule is satisfied, the feature action module 418 is instructed to select the first complexity level of a feature to implement the feature on the client device 102. In an embodiment, the second complexity level of the feature is associated with a second configuration rule that includes the following Boolean expression (application version is greater than 10 AND user is an application developer of the messaging client application 104 AND bandwidth available to the client device 102 is greater than 2 Mbps). If the configuration rule evaluation module 416 determines that this Boolean expression of the second configuration rule is satisfied, the feature action module 418 is instructed to select the second complexity level for the feature to implement the feature on the client device 102. In an embodiment, the third complexity level of the feature is associated with a third configuration rule that includes the following Boolean expression (application version is greater than 7 AND the user is located in a specified country, such as Brazil AND bandwidth available to the client device 102 is less than 512 kbps). If the configuration rule evaluation module 416 determines that this Boolean expression of the third configuration rule is satisfied, the feature action module 418 is instructed to select the third complexity level for implementing the feature on the client device 102.
In some embodiments, the feature selection module 411 selects a complexity level for implementing the feature based on what is commonly selected as the complexity level for the feature among a group of devices that are associated with a collection of friends. For example, if a majority of friends in a given group have a given feature scaled down that allows video decoding or transcoding using a first decoding or transcoding technique, other users in the same group of friends may also have the same feature scaled down. The other users may have capabilities that allow a second feature to be enabled that allows for video decoding or transcoding using a second decoding or transcoding technique, wherein the second decoding or transcoding technique is more complex than the first decoding or transcoding technique. But because the majority of users in the group have the given feature scaled down, the feature selection module 411 selects the lower complexity level for implementing the given feature rather than the higher complexity level for implementing the feature on the client devices 102 of the other users. In this way, all the users in the particular group are able to share media with each other in the same format that each of the users can process.
At operation 501, the automatic feature scaling system 124 selects a messaging application feature. For example, the feature selection module 411 selects a given feature of the messaging client application 104 to be scaled up or scaled down.
At operation 502, the automatic feature scaling system 124 accesses a configuration rule that includes a configuration rule expression associated with the messaging application feature. For example, the configuration rule selection module 419 retrieves one or more configuration rules that are associated with the selected feature provided by the feature selection module 411.
At operation 503, the automatic feature scaling system 124 evaluates a first portion of the expression on a server. For example, the configuration rule evaluation module 416 obtains data for one or more parameters of the configuration rule expression from the user information module 414 and/or device properties module 412 and determines whether a Boolean expression in the configuration rule is satisfied.
At operation 504, the automatic feature scaling system 124 determines if the first portion of the expression is satisfied. In response to determining that the first portion of the expression is satisfied, the process continues to operation 505; otherwise the process continues to operation 501.
At operation 505, the automatic feature scaling system 124 transmits a second portion of the expression to a client device 102. For example, the configuration rule evaluation module 416 identifies a portion of the configuration rule that needs to be evaluated on the client device 102, such as a benchmark that needs to be run on the client device 102 to determine the performance of the benchmark or the currently available bandwidth, battery level, or storage space on the client device 102.
At operation 506, the automatic feature scaling system 124 evaluates the second portion of the expression on the client device 102. For example, the configuration rule evaluation module 416 instructs the client device 102 to evaluate the portion of the rule and transmit an indication of whether the portion of the rule (e.g., the Boolean expression portion) matches the data obtained on the client device 102 and evaluates to be TRUE or FALSE.
At operation 507, the automatic feature scaling system 124 determines if the second portion of the expression is satisfied. In response to determining that the second portion of the expression is satisfied, the process continues to operation 508; otherwise the process continues to operation 501. For example, if the second portion is not satisfied, the feature action module 418 causes the feature of the messaging client application 104 to operate on the client device at a second complexity level of a plurality of selectable complexity levels that is lower than a first complexity level of the plurality of selectable complexity levels.
At operation 508, the automatic feature scaling system 124 performs an action associated with the messaging application feature. For example, the feature action module 418 scales down the feature of the messaging client application 104 on the client device 102 to operate at a lower complexity level, such as by sending code segments for implementing and executing the selected complexity level of the feature on the client device 102. As another example, the feature action module 418 scales up the feature and causes the feature of the messaging client application 104 to operate on the client device at the first complexity level that is greater than the second complexity level.
At operation 601, the automatic feature scaling system 124 provides a messaging application comprising a feature to a client device, the feature being implemented by one or more operations having a plurality of alternative complexity levels, wherein a first complexity level of the plurality of alternative complexity levels represents a first amount of device resources consumed by a first set of the one or more operations that implement the feature, and wherein a second complexity level of the plurality of alternative complexity levels represents a second amount of device resources consumed by a second set of the one or more operations that implement the feature.
At operation 602, the automatic feature scaling system 124 accesses a first configuration rule of a plurality of configuration rules that associates a first device property rule with the feature of the messaging application.
At operation 603, the automatic feature scaling system 124 determines that the first configuration rule is satisfied by a first property of the client device.
At operation 604, the automatic feature scaling system 124, in response to determining that the first configuration rule is satisfied by the first property of the client device, causes the feature to be implemented on the client device by the first set of the one or more operations having the first complexity level that consume a greater amount of device resources than the second set of the one or more operations having the second complexity level.
As mentioned, the map GUI 612 includes a number of different user-selectable icons or UI elements that indicate different geographically-based content or information. These icons can include the global event avatar discussed below in connection with
In the example embodiment of
In this example embodiment, the social media items that are selectively playable by selection of the corresponding story icons 631, 633 in the map GUI 612 are ephemeral social media items or messages. Ephemeral content is social media content (e.g., augmented and/or unaugmented video clips, pictures, and/or other messages) that is available for viewing by social media users via the map GUI 612 for only a predetermined limited period (also referred to herein as a respective gallery participation parameter or timer). After expiry of a respective gallery participation parameter or timer for any ephemeral message or snap uploaded by a particular user, that ephemeral message or snap is no longer available for viewing by other users via the map GUI 612 generated on their respective client devices 103 (such as mobile phone 102). Current examples of such ephemeral social media content include the respective snaps or messages included in so-called Stories in the SNAPCHAT or the INSTAGRAM social media applications.
Instead of, or in addition to, management of ephemerality on a per-snap level using respective gallery participation timers, availability of the ephemeral messages by the map GUI 612 can, in some instances, be managed collectively (e.g., on a per-story level). In such instances, each story or gallery can have a respective story duration parameter, at the expiry of which availability of the corresponding story for viewing via map GUI 612 is terminated. In some embodiments, the story duration parameter is calculated based on the story participation parameter of one of the ephemeral messages included in the relevant story. For example, a story may, in some embodiments, expire when a last uploaded item within the story expires, responsive to which the corresponding story icon 631/633 is no longer displayed on the map GUI 612. In one example embodiment, the map GUI 612 may include one or more event icons corresponding to respective event stories, with the story duration parameter of the event story being set to expire a predetermined period of time from a start or conclusion of the underlying event. At expiry of the story duration parameter, the corresponding gallery icon is removed from the map GUI 612, irrespective of individual timers associated with respective snaps included in the event story.
The user can select any one of the gallery icons 631, 633 by haptic contact with the touchscreen 606 at the onscreen location of the selected gallery icon 631, 633. Responsive to such selection, automated sequential playback of the corresponding set of ephemeral messages or snaps in the selected story is performed by the mobile phone 102 on the touchscreen 606. In an embodiment, the set of ephemeral messages or snaps in the selected story that are sequentially played back include any content. Such automated sequential reproduction of the selected story consists of:
In some embodiments, not all of the snaps in a particular story/gallery are necessarily included in the replay sequence. For example, if there are many overlapping snaps (e.g., snaps showing substantially identical content), some of those snaps are automatically skipped to keep a continuous narrative and not repeat some sections of an event commonly captured by the different snaps. Instead, or in addition, the messaging server application 114 can, in some embodiments, be programmed to automatically identify and curate overlapping or contemporaneous snaps based on timestamp information associated with respective snaps.
In this example embodiment, the snaps automatically collected together in a replayable spike story or place story are arranged automatically to be played back in chronological order based on respective timestamps (i.e., being played in sequence from oldest to newest or earliest posted to most recently posted). A benefit of such chronological playback is that viewing of the story provides a user with sequentially arranged views of events transpiring at the relevant location. In some instances, however, a human curator may choose to rearrange snaps out of chronological order (for example, to improve the narrative flow of the story). In other embodiments, the snaps may be played in reverse chronological order, from newest to oldest.
It can thus be seen that the example map GUI 612 includes multiple location-based gallery icons in the example form of story icons 631, 633 that are user-selectable to trigger playback of respective collections of ephemeral social media items, in this example embodiment being respective ephemeral stories consisting of respective sets of ephemeral messages (also referred to in this description as snaps). In this example embodiment, each of the plurality of location-based stories represented by the respective story icons 631, 633 may comprise media content contributed by multiple different users.
The respective ephemeral stories are, in this example embodiment, compiled from ephemeral messages submitted by multiple users based at least in part on geo-tagging of the respective snaps. Note that the ephemeral messages made available for viewing via the map GUI 612 are, in this example embodiment, not limited to content provided by other users who are members of an in-application social network of the user on whose mobile phone 102 the map GUI 612 is generated. Instead, the social media content to which the map GUI 612 allows access is, in this example embodiment, provided by snaps uploaded or submitted by any user to be publicly accessible via the map GUI 612.
One aspect of the example map GUI 612 provides for the functionality for users to submit social media content that is publicly viewable via the map GUI 612. In this example embodiment, snaps can be captured via the map GUI 612 while the map viewport 621 is displayed (as seen in
In other example embodiments described herein, the superset of ephemeral messages made available by multiple users for public viewing via the map GUI 612 is alternatively referred to as the “Live Story” or simply as a “Live” gallery. For the purposes of the description of example embodiments herein, Live and Our Story are thus to be read as being synonymous. In the present example embodiment, the compilation and/or surfacing of gallery icons 631, 633, and the rendering of the heatmap 625 are based exclusively on publicly available social media content provided by snaps uploaded to Our Story. Calculation of metrics or attributes of social media activity upon which one or more aspects of the map GUI 612 are based (e.g., an unusualness or anomaly metric indicating geo-temporal unusualness or anomaly of social media activity within respective geographical areas) is, in this example embodiment, likewise based exclusively on snaps uploaded to Our Story.
In addition to viewing clustered stories by selection of the story icons 631, 633, the user can access snaps by use of one or more search functionalities provided by the map GUI 612. In this example embodiment, the map GUI 612 provides two separate search mechanisms: a search box 665 (
Responsive to entry of a text search query in the search box 665, search results are, in this example embodiment, displayed in a search box drop-down in which individual cells correspond to individual snaps, stories, places, and/or users returned in the search. When the user clicks on a selected cell in the search box drop-down, the map GUI 612 in this example automatically navigates with a fly-over to the point on the map, after which the selected story or spike cluster starts playing or a friend bubble pops up. In some embodiments, at least some aspects of the text-based query are limited to the geographical area currently displayed in the map viewport 621. Instead, or in addition, some aspects of the text-based query may be location-agnostic, returning search results from any location.
As an alternative to entering a text-based search query, the user can initiate a location-based search by clicking or tapping on a particular location on the map viewport 621, responsive to which a search is conducted for social media items within a predefined radius from the click or tap location. In this example embodiment, such a location-based search does not return a list of GUI elements that are selectable to play respective items, but instead automatically triggers automated sequential replay returned as a result of the search. Thus, clicking or tapping on a non-thumbnail place on the map 618 will radiate out a search around the tap location. Such a location-based search can have a predefined search radius from the tap location. If any snaps are found, they are automatically played back in sequence, as described before. If there are no snaps in that area, the search bounces back to show no results found.
In embodiments in which the map GUI 612 is displayed on a touchscreen 606, a geo-temporal search is triggered by haptic contact at a particular location within the map 618, with the search being geographically centered on the location of the haptic contact. An input interval indicated by the time period for which the haptic contact is maintained with the touchscreen automatically determines the preceding time period with respect to which the search is carried out. In such a case, for example, a tap on the screen triggers a geo-temporal search for material within the default time period, while a press and hold automatically triggers a geo-temporal search for material within an extended time period which is longer than the default time period. Instead, or in addition, the search radius may be variable based on the length of the input interval, with longer input intervals (i.e., a longer hold period) corresponding to a larger search radius.
In use, the map GUI 612 thus surfaces different types of location-based stories, which the user can view from the map 618. In the example embodiment of
In this example embodiment, the map 618 is not selectively rotatable by the user, having a fixed default orientation relative to the touchscreen 606. In other embodiments, the map 618 may have a fixed orientation relative to the Earth. In some embodiments, the map 618 is selectively rotatable, e.g., with all map content rotating around a fixed anchor.
As discussed at length above, in any particular map viewport 621, the displayed information can include:
In some embodiments, no spike icons 633 are shown at some levels of magnification. In a particular example embodiment, no spike icons 633 are shown at the original zoom level at which the map GUI 612 loads by default. In such an example, only the heatmap 625, friend bitmojis 640, and a number of place icons 631 are displayed on the map 618 at the original zoom level. As the user zooms in, spike icons 633 are surfaced, representing respective clusters of activity.
It will be appreciated that different icons 631, 633 are surfaced at different zoom levels. In this example embodiment, the map GUI 612 displays no more than a predefined maximum number of place icons 631 and no more than a predefined maximum number of spike icons 633 in any particular view. For example, at any zoom level, the top three place stories (ranked by snap volume) are surfaced by displaying respective place icons 631 in the map viewport 621. Likewise, at any zoom level, the top three spike stories (ranked by anomaly or unusualness metric value) are surfaced by displaying respective spike icons 633 in the map viewport 621.
In addition to viewing stories surfaced in the map 618 by respective story icons 631, 633, the user can use one or more of the search functionalities described above to access any snap uploaded to Our Story and whose gallery participation timer or availability lifetime has not yet expired.
It will be appreciated that the map GUI 612 is dynamic, in that the information displayed therein changes dynamically with time. New snaps may continually be uploaded to Our Story, while the underlying social media items upon which surfacing of the story icons 631, 633 and generation of the heatmap 625 are based may further continually change due to the expiration of the availability of snaps. In this example embodiment, however, the information displayed in the map viewport 621 is not dynamically updated during display of any particular geographical area. Instead, changing of the focus of the map viewport 621 is associated with receiving updated information with respect to the story icons 631, 633 and heatmap 625 from the application server 112.
A benefit of the map GUI 612 as described with the example embodiments is that it provides for user-friendly and intuitive interaction with geographically distributed social media content. The provision of different types of social media galleries (e.g., represented respectively by spike icons 633 and place icons 631) provides a system that automatically surfaces the most relevant content for user-selection in such a manner that the very large number of individual social media items that may be available via a social media platform is reduced in complexity and allows selection of targeted content in which the user might be interested.
The automatic feature scaling system 124 determines whether a feature of the GUI 612 is to be operated at a first complexity level or a second complexity level, where the first complexity level is greater than the second complexity level. The feature may correspond to a map-based GUI 612 of the messaging client application 104. If the feature is to operate at the first complexity level (e.g., because the automatic feature scaling system 124 determines that the client properties and/or user information 221 do satisfy and match the expression in a corresponding configuration rule), as shown in the GUI 612 (
In the example architecture of
The operating system 902 may manage hardware resources and provide common services. The operating system 902 may include, for example, a kernel 922, services 924, and drivers 926. The kernel 922 may act as an abstraction layer between the hardware and the other software layers. For example, the kernel 922 may be responsible for memory management, processor management (e.g., scheduling), component management, networking, security settings, and so on. The services 924 may provide other common services for the other software layers. The drivers 926 are responsible for controlling or interfacing with the underlying hardware. For instance, the drivers 926 include display drivers, camera drivers, Bluetooth® drivers, flash memory drivers, serial communication drivers (e.g., Universal Serial Bus (USB) drivers), Wi-Fi® drivers, audio drivers, power management drivers, and so forth, depending on the hardware configuration.
The libraries 920 provide a common infrastructure that is used by the applications 916 and/or other components and/or layers. The libraries 920 provide functionality that allows other software components to perform tasks in an easier fashion than by interfacing directly with the underlying operating system 902 functionality (e.g., kernel 922, services 924, and/or drivers 926). The libraries 920 may include system libraries 944 (e.g., C standard library) that may provide functions such as memory allocation functions, string manipulation functions, mathematical functions, and the like. In addition, the libraries 920 may include API libraries 946 such as media libraries (e.g., libraries to support presentation and manipulation of various media formats such as MPEG4, H.264, MP3, AAC, AMR, JPG, PNG), graphics libraries (e.g., an OpenGL framework that may be used to render two-dimensional and three-dimensional graphic content on a display), database libraries (e.g., SQLite that may provide various relational database functions), web libraries (e.g., WebKit that may provide web browsing functionality), and the like. The libraries 920 may also include a wide variety of other libraries 948 to provide many other APIs to the applications 916 and other software components/modules.
The frameworks/middleware 918 (also sometimes referred to as middleware) provide a higher-level common infrastructure that may be used by the applications 916 and/or other software components/modules. For example, the frameworks/middleware 918 may provide various graphic UI (GUI) functions, high-level resource management, high-level location services, and so forth. The frameworks/middleware 918 may provide a broad spectrum of other APIs that may be utilized by the applications 916 and/or other software components/modules, some of which may be specific to a particular operating system 902 or platform.
The applications 916 include built-in applications 938 and/or third-party applications 940. Examples of representative built-in applications 938 may include, but are not limited to, a contacts application, a browser application, a book reader application, a location application, a media application, a messaging application, and/or a game application. The third-party applications 940 may include an application developed using the ANDROID™ or IOS™ software development kit (SDK) by an entity other than the vendor of the particular platform, and may be mobile software running on a mobile operating system such as IOS™, ANDROID™, WINDOWS® Phone, or other mobile operating systems. The third-party applications 940 may invoke the API calls 908 provided by the mobile operating system (such as the operating system 902) to facilitate functionality described herein.
The applications 916 may use built-in operating system functions (e.g., kernel 922, services 924, and/or drivers 926), libraries 920, and frameworks/middleware 918 to create UIs to interact with users of the system. Alternatively, or additionally, in some systems, interactions with a user may occur through a presentation layer, such as the presentation layer 914. In these systems, the application/component “logic” can be separated from the aspects of the application/component that interact with a user.
The machine 1000 may include processors 1004, memory/storage 1006, and I/O components 1018, which may be configured to communicate with each other such as via a bus 1002. In an example embodiment, the processors 1004 (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 1008 and a processor 1012 that may execute the instructions 1010. The term “processor” is intended to include multi-core processors 1004 that may comprise two or more independent processors 1008 (sometimes referred to as “cores”) that may execute instructions 1010 contemporaneously. Although
The memory/storage 1006 may include a memory 1014, such as a main memory, or other memory storage, and a storage unit 1016, both accessible to the processors 1004 such as via the bus 1002. The storage unit 1016 and memory 1014 store the instructions 1010 embodying any one or more of the methodologies or functions described herein. The instructions 1010 may also reside, completely or partially, within the memory 1014, within the storage unit 1016, within at least one of the processors 1004 (e.g., within the processor 1008's cache memory), or any suitable combination thereof, during execution thereof by the machine 1000. Accordingly, the memory 1014, the storage unit 1016, and the memory of the processors 1004 are examples of machine-readable media.
The I/O components 1018 may include a wide variety of components to receive input, provide output, produce output, transmit information, exchange information, capture measurements, and so on. The specific I/O components 1018 that are included in a particular machine 1000 will depend on the type of machine 1000. For example, portable machines such as mobile phones will likely include a touch input device or other such input mechanisms, while a headless server machine will likely not include such a touch input device. It will be appreciated that the I/O components 1018 may include many other components that are not shown in
In further example embodiments, the I/O components 1018 may include biometric components 1039, motion components 1034, environmental components 1036, or position components 1038 among a wide array of other components. For example, the biometric components 1039 may include components to detect expressions (e.g., hand expressions, facial expressions, vocal expressions, body gestures, or eye tracking), measure biosignals (e.g., blood pressure, heart rate, body temperature, perspiration, or brain waves), identify a person (e.g., by voice identification, retinal identification, facial identification, fingerprint identification, or electroencephalogram-based identification), and the like. The motion components 1034 may include acceleration sensor components (e.g., accelerometer), gravitation sensor components, rotation sensor components (e.g., gyroscope), and so forth. The environmental components 1036 may include, for example, illumination sensor components (e.g., photometer), temperature sensor components (e.g., one or more thermometers that detect ambient temperature), humidity sensor components, pressure sensor components (e.g., barometer), 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 sensors to detect concentrations of hazardous gases for safety or to measure pollutants in the atmosphere), or other components that may provide indications, measurements, or signals corresponding to a surrounding physical environment. The position components 1038 may include location sensor components (e.g., a GPS receiver component), altitude sensor components (e.g., altimeters or barometers that detect air pressure from which altitude may be derived), orientation sensor components (e.g., magnetometers), and the like.
Communication may be implemented using a wide variety of technologies. The I/O components 1018 may include communication components 1040 operable to couple the machine 1000 to a network 1037 or devices 1029 via a coupling 1024 and a coupling 1022, respectively. For example, the communication components 1040 may include a network interface component or other suitable device to interface with the network 1037. In further examples, the communication components 1040 may include wired communication components, wireless communication components, cellular communication components, near field communication (NFC) components, Bluetooth® components (e.g., Bluetooth® Low Energy), Wi-Fi® components, and other communication components to provide communication via other modalities. The devices 1029 may be another machine or any of a wide variety of peripheral devices (e.g., a peripheral device coupled via a USB).
Moreover, the communication components 1040 may detect identifiers or include components operable to detect identifiers. For example, the communication components 1040 may include radio frequency identification (RFID) tag reader components, NFC smart tag detection components, optical reader components (e.g., an optical sensor to detect one-dimensional bar codes such as Universal Product Code (UPC) bar code, multi-dimensional bar codes such as Quick Response (QR) code, Aztec code, Data Matrix, Dataglyph, MaxiCode, PDF417, Ultra Code, UCC RSS-2D bar code, and other optical codes), or acoustic detection components (e.g., microphones to identify tagged audio signals). In addition, a variety of information may be derived via the communication components 1040, such as location via Internet Protocol (IP) geolocation, location via Wi-Fi® signal triangulation, location via detecting an NFC beacon signal that may indicate a particular location, and so forth.
“CARRIER SIGNAL,” in this context, refers to any intangible medium that is capable of storing, encoding, or carrying transitory or non-transitory instructions 1010 for execution by the machine 1000, and includes digital or analog communications signals or other intangible media to facilitate communication of such instructions 1010. Instructions 1010 may be transmitted or received over the network 1037 using a transitory or non-transitory transmission medium via a network interface device and using any one of a number of well-known transfer protocols.
“CLIENT DEVICE,” in this context, refers to any machine 1000 that interfaces to a communications network 1037 to obtain resources from one or more server systems or other client devices 102. A client device 102 may be, but is not limited to, a mobile phone, desktop computer, laptop, PDA, smart phone, tablet, ultra book, netbook, laptop, multi-processor system, microprocessor-based or programmable consumer electronics system, game console, set-top box, or any other communication device that a user may use to access a network 1037.
“COMMUNICATIONS NETWORK,” in this context, refers to one or more portions of a network 1037 that may be an ad hoc network, an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a wireless WAN (WWAN), a metropolitan area network (MAN), the Internet, a portion of the Internet, a portion of the Public Switched Telephone Network (PSTN), a plain old telephone service (POTS) network, a cellular telephone network, a wireless network, a Wi-Fi® network, another type of network, or a combination of two or more such networks. For example, a network 1037 or a portion of a network may include a wireless or cellular network and the coupling may be a Code Division Multiple Access (CDMA) connection, a Global System for Mobile communications (GSM) connection, or another type of cellular or wireless coupling. In this example, the coupling may implement any of a variety of types of data transfer technology, such as Single Carrier Radio Transmission Technology (1×RTT), Evolution-Data Optimized (EVDO) technology, General Packet Radio Service (GPRS) technology, Enhanced Data rates for GSM Evolution (EDGE) technology, third Generation Partnership Project (3GPP) including 3G, fourth generation wireless (4G) networks, Universal Mobile Telecommunications System (UMTS), High-Speed Packet Access (HSPA), Worldwide Interoperability for Microwave Access (WiMAX), Long-Term Evolution (LTE) standard, others defined by various standard-setting organizations, other long-range protocols, or other data transfer technology.
“EPHEMERAL MESSAGE,” in this context, refers to a message 300 that is accessible for a time-limited duration. An ephemeral message may be a text, an image, a video, and the like. The access time for the ephemeral message may be set by the message sender. Alternatively, the access time may be a default setting or a setting specified by the recipient. Regardless of the setting technique, the message 300 is transitory.
“MACHINE-READABLE MEDIUM,” in this context, refers to a component, a device, or other tangible media able to store instructions 1010 and data temporarily or permanently and may include, but is not limited to, random-access memory (RAM), read-only memory (ROM), buffer memory, flash memory, optical media, magnetic media, cache memory, other types of storage (e.g., erasable programmable read-only memory (EPROM)), and/or any suitable combination thereof. The term “machine-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, or associated caches and servers) able to store instructions 1010. The term “machine-readable medium” shall also be taken to include any medium, or combination of multiple media, that is capable of storing instructions 1010 (e.g., code) for execution by a machine 1000, such that the instructions 1010, when executed by one or more processors 1004 of the machine 1000, cause the machine 1000 to perform any one or more of the methodologies described herein. Accordingly, a “machine-readable medium” refers to a single storage apparatus or device, as well as “cloud-based” storage systems or storage networks that include multiple storage apparatus or devices. The term “machine-readable medium” excludes signals per se.
“COMPONENT,” in this context, refers to a device, physical entity, or logic having boundaries defined by function or subroutine calls, branch points, APIs, or other technologies that provide for the partitioning or modularization of particular processing or control functions. Components may be combined via their interfaces with other components to carry out a machine process. A component may be a packaged functional hardware unit designed for use with other components and a part of a program that usually performs a particular function of related functions. Components may constitute either software components (e.g., code embodied on a machine-readable medium) or hardware components. A “hardware component” is a tangible unit capable of performing certain operations and may be configured or arranged in a certain physical manner. In various example embodiments, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware components of a computer system (e.g., a processor or a group of processors 1004) may be configured by software (e.g., an application or application portion) as a hardware component that operates to perform certain operations as described herein.
A hardware component may also be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware component may include dedicated circuitry or logic that is permanently configured to perform certain operations. A hardware component may be a special-purpose processor, such as a field-programmable gate array (FPGA) or an ASIC. A hardware component may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, a hardware component may include software executed by a general-purpose processor 1004 or other programmable processor. Once configured by such software, hardware components become specific machines (or specific components of a machine) uniquely tailored to perform the configured functions and are no longer general-purpose processors 1004. It will be appreciated that the decision to implement a hardware component mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) may be driven by cost and time considerations. Accordingly, the phrase “hardware component” (or “hardware-implemented component”) should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. Considering embodiments in which hardware components are temporarily configured (e.g., programmed), each of the hardware components need not be configured or instantiated at any one instant in time. For example, where a hardware component comprises a general-purpose processor 1008 configured by software to become a special-purpose processor, the general-purpose processor 1008 may be configured as respectively different special-purpose processors (e.g., comprising different hardware components) at different times. Software accordingly configures a particular processor or processors 1004, for example, to constitute a particular hardware component at one instant of time and to constitute a different hardware component at a different instant of time.
Hardware components can provide information to, and receive information from, other hardware components. Accordingly, the described hardware components may be regarded as being communicatively coupled. Where multiple hardware components exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) between or among two or more of the hardware components. In embodiments in which multiple hardware components are configured or instantiated at different times, communications between such hardware components may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware components have access. For example, one hardware component may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware component may then, at a later time, access the memory device to retrieve and process the stored output.
Hardware components may also initiate communications with input or output devices and can operate on a resource (e.g., a collection of information). The various operations of example methods described herein may be performed, at least partially, by one or more processors 1004 that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented components that operate to perform one or more operations or functions described herein. As used herein, “processor-implemented component” refers to a hardware component implemented using one or more processors 1004. Similarly, the methods described herein may be at least partially processor-implemented, with a particular processor or processors 1004 being an example of hardware. For example, at least some of the operations of a method may be performed by one or more processors 1004 or processor-implemented components. Moreover, the one or more processors 1004 may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines 1000 including processors 1004), with these operations being accessible via a network 1037 (e.g., the Internet) and via one or more appropriate interfaces (e.g., an API). The performance of certain of the operations may be distributed among the processors 1004, not only residing within a single machine 1000, but deployed across a number of machines 1000. In some example embodiments, the processors 1004 or processor-implemented components may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other example embodiments, the processors 1004 or processor-implemented components may be distributed across a number of geographic locations.
“PROCESSOR,” in this context, refers to any circuit or virtual circuit (a physical circuit emulated by logic executing on an actual processor 1008) that manipulates data values according to control signals (e.g., “commands,” “op codes,” “machine code,” etc.) and which produces corresponding output signals that are applied to operate a machine 1000. A processor 1008 may, for example, be a CPU, a RISC processor, a CISC processor, a GPU, a DSP, an ASIC, a RFIC, or any combination thereof. A processor 1008 may further be a multi-core processor having two or more independent processors 1008 (sometimes referred to as “cores”) that may execute instructions 1010 contemporaneously.
“TIME STAMP,” in this context, refers to a sequence of characters or encoded information identifying when a certain event occurred, for example giving date and time of day, sometimes accurate to a small fraction of a second.
Changes and modifications may be made to the disclosed embodiments without departing from the scope of the present disclosure. These and other changes or modifications are intended to be included within the scope of the present disclosure, as expressed in the following claims.
