Title: Location-based address book tailored for use during upcoming travel

Description:
BACKGROUND 
     Many personal electronic devices (such as mobile phones and the like) include a contact list function such as an address book which displays selected personal data from a database concerning individuals and/or businesses and other such entities. Contact data may include a name, mailing address, phone number(s), e-mail address, company, job title, and sometimes an image for each entry. Address books may be stored locally in a user&#39;s electronic device or online. Online address books may invite people to register and then upload contact information for people belonging to their personal and business network. 
     A contact entry in an address book may be assigned to one or more groups of contacts. For example, certain contacts may be assigned to a group designated “local contacts,” who are contacts who work and/or reside in the same geographic region as the user. Additionally, location-based services are available which can tell a user if any of his or her contacts are currently nearby. 
     This background is provided to introduce a brief context for the summary and detailed description that follow. This background is not intended to be an aid in determining the scope of the claimed subject matter nor be viewed as limiting the claimed subject matter to implementations that solve any or all of the disadvantages or problems presented above. 
     SUMMARY 
     A location-based address book component operating on a mobile computing device such as a smartphone, tablet, or laptop personal computer (pc) is configured to enable a user to generate a group of the user&#39;s contacts who may be traveling to the same location as the user at some time in future. Not only does this eliminate the need for the user to search through numerous contacts to locate contacts the user knows in advance will visiting the specified location, it can also identify contacts whom the user did not know would visiting that location at the same time as the user. 
     In various illustrative examples, the location-based address book component, alone or in coordination with one or more other components such as a personal digital assistant component, can collect contextual data concerning the online activities of the user&#39;s contacts to infer or otherwise determine if one or more of the user contacts may be visiting the same geographic location as the user at some common time in the future. The location-based address book component may then populate a location-based contact list with those user contacts so that they are easily accessible to the user. 
     This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure. It may be appreciated that the above-described subject matter may be implemented as a computer-controlled apparatus, a computer process, a computing system, or as an article of manufacture such as one or more computer-readable storage media. These and various other features may be apparent from a reading of the following Detailed Description and a review of the associated drawings.

     DETAILED DESCRIPTION 
       FIG. 1  shows an illustrative communications environment  100  in which various users  105  employ respective devices  110  that communicate over a communications network  115 . The devices  110  provide various communication capabilities, such as voice and video calling and messaging, and typically support data-consuming applications such as Internet browsing and multimedia (e.g., music, video, etc.) consumption in addition to various other features. The devices  110  may include, for example, user equipment, mobile phones, cell phones, feature phones, tablet computers, and smartphones which users often employ to make and receive voice and/or multimedia (i.e., video) calls, engage in messaging (e.g., texting), use applications and access services that employ data, browse the World Wide Web, and the like. However, alternative types of electronic devices are also envisioned to be usable within the communications environment  100  so long as they are configured with communication capabilities and can connect to the communications network  115 . Such alternative devices variously include handheld computing devices, PDAs (personal digital assistants), portable media players, phablet devices (i.e., combination smartphone/tablet devices), wearable computing devices (e.g., glasses, watches, etc.), navigation devices such as GPS (Global Positioning System) systems, laptop PCs (personal computers), or the like. In the discussion that follows, the use of the term “device” is intended to cover all devices that are configured with communication capabilities and are capable of connectivity to the communications network  115 . 
     The various devices  110  in the environment  100  can support different features, functionalities, and capabilities (here referred to generally as “features”). Some of the features supported on a given device can be similar to those supported on others, while other features may be unique to a given device. The degree of overlap and/or distinctiveness among features supported on the various devices  110  can vary by implementation. For example, some devices  110  can support touch controls, gesture recognition, and voice commands, while others may enable a more limited UI. Some devices may support video consumption and Internet browsing, while other devices may support more limited media handling and network interface features. 
     As shown, the devices  110  can access the communications network  115  in order to implement various user experiences. The communications network can include any of a variety of network types and network infrastructure in various combinations or sub-combinations including cellular networks, satellite networks, IP (Internet Protocol) networks such as Wi-Fi and Ethernet networks, a public switched telephone network (PSTN), and/or short range networks such as Bluetooth networks. The network infrastructure can be supported, for example, by mobile operators, enterprises, Internet service providers (ISPs), telephone service providers, data service providers, and the like. The communications network  115  typically includes interfaces that support a connection to the Internet  120  so that the mobile devices  110  can access content provided by one or more content providers  125  and access a service provider  130  in some cases. 
     The devices  110  and communications network  115  may be configured to enable device-to-device communication. As shown in  FIG. 2 , such device-to-device communications  200  can include, for example, voice calls  205 , messaging conversations  210 , and video calls  215 . Support for device-to-device communications  200  may be provided using various applications that run on a device  110 . 
     The present location-based address book may be implemented using components that are instantiated on a given device. In addition, the location-based address book functionality can also be implemented, in whole or part, using a web service supported by a remote service provider (e.g., service provider  130  in  FIG. 1 ).  FIG. 3  shows an illustrative layered architecture  400  that supports communication applications and other components. The architecture  400  is typically implemented in software, although combinations of software, firmware, and/or hardware may also be utilized in some cases. The architecture  400  is arranged in layers and includes an application layer  405 , an OS (operating system) layer  410 , and a hardware layer  415 . The hardware layer  415  provides an abstraction of the various hardware used by the device  110  (e.g., input and output devices, networking and radio hardware, etc.) to the layers above it. In this illustrative example, the hardware layer supports a microphone  420  and audio endpoint  425  which may include, for example, a wired or wireless headset/earpiece, external speaker/device, and the like, and the device&#39;s speakerphone  428 . 
     The application layer  405  in this illustrative example supports various applications (apps)  430  (e.g., web browser, map application, email application, etc.), as well as a phone app  435 , messaging app  440 , and video calling app  445 , such as Skype™ and an address book app  448 . The applications are often implemented using locally executing code. However in some cases, these applications may rely on services and/or remote code execution provided by remote servers or other computing platforms such as those supported by the service provider  130  or other cloud-based resources as indicated by line  460 . While the apps  430 ,  435 ,  440 ,  445  and  448  are shown here as components that are instantiated in the application layer  405 , it may be appreciated that the functionality provided by a given application may be implemented, in whole or part, using components that are supported in either the OS or hardware layers. 
     The OS layer  410  supports a location-based address book component  450  and various other OS components  455 . In some cases, location-based address book component  450  can interact with the service provider. That is, the location-based address book component  450  in some implementations can partially utilize or fully utilize remote code execution supported at the service provider  130 , or using other remote resources. In addition, it may utilize and/or interact with the other OS components  455  (and/or other components that are instantiated in the other layers of the architecture  400 ) as may be needed to implement the various features and functions described herein. The location-based address book component  450  may alternatively be instantiated using elements that are instantiated in both the OS and application layers or be configured as an application, as shown in  FIG. 3  using the dashed-line ovals. It may also be appreciated that the functionality provided by the location-based address book component  450  can be implemented, in whole or part, using components that are supported in either the application or hardware layers. 
     A user can typically interact with the location-based address book component  450  ( FIG. 3 ) in a number of ways depending on the features and functionalities supported by a given device  110 . For example, as shown in  FIG. 4 , the location-based address book component  450  may expose a tangible user interface  505  that enables the user  105  to employ physical interactions  510  in support of the location sharing experiences on the device  110 . Such physical interactions can include manipulation of physical and/or virtual controls such as buttons, menus, keyboards, etc., using touch-based inputs like tapping, flicking, dragging, etc. on a touchscreen, and the like. In some implementations, the location-based address book component may expose a natural language user interface  605  shown in  FIG. 5 , or alternatively a voice command-based user interface (not shown), with which the user employs voice  610  to provide various inputs to the device  110 . In other implementations, the location-based address book component  450  may expose a gesture user interface  705  shown in  FIG. 6  with which the user  105  employs gestures  710  to provide inputs to the device  110 . It is noted that in some cases, combinations of user interfaces may be utilized where the user may employ, for example, both voice and physical inputs to interact with the location-based address book component  450  and the device  110 . The user gestures can be sensed using various techniques such as optical sensing, touch sensing, proximity sensing, and the like. 
     In accordance with one aspect of the disclosure, the location-based address book component  450  generates an ad hoc subset of the user&#39;s contacts who are going to be traveling to the same location as the user at some upcoming time in the future. That is, a subset of the user&#39;s contact list is dynamically generated and populated with any user contacts who the user might meet with or otherwise contact during an upcoming trip. By way of example, if the user is planning to attend a conference in Los Angeles from April 5-9, it would helpful to know that Mary, who is one of the user&#39;s contacts and lives in Maine, will also be in Los Angeles from say, April 3-6, either because she is attending or same conference or for some other totally unrelated reason. 
     Additional contacts may be added to the location-based contact list generated by the location-based address book component  450  even though they are not part of the user&#39;s main contact list. Specifically, certain categories of contacts may be added to the user&#39;s location-based contact list and may be dynamically populated with contact records that are relevant to the particular locale that the user will be visiting during the upcoming trip. For example, telephone numbers for taxi companies, public transit, restaurants, and emergency services, may be automatically added to the list, either in advance of the trip or when the user arrives at the location. 
       FIG. 7  shows an illustrative taxonomy of functions  800  that may typically be supported by the location-based address book component  450 . Inputs to the location-based address book component  450  typically can include user input  805 , data from internal sources  810 , and data from external sources  815 . For example, data from internal sources  810  could include data from locally installed applications and databases and data from various sensors such as the current geolocation of the device  110  that may be reported by a GPS (Global Positioning System) component on the device, or some other location-aware component. The externally sourced data  815  includes data provided, for example, by external systems, databases, services, and the like such as the service provider  130  ( FIG. 1 ). The various inputs can be used alone or in various combinations to enable the location-based address book component  450  to utilize contextual data  820  when it operates. 
     Contextual data  820  can include, for example, time/date, the user&#39;s location, language, schedule, applications installed on the device, the user&#39;s preferences, the user&#39;s behaviors (in which such behaviors are monitored/tracked with notice to the user and the user&#39;s consent), stored contacts (including, in some cases, links to a local user&#39;s or remote user&#39;s social graph such as those maintained by external social networking services), call history, messaging history, browsing history, device type, device capabilities, communications network type and/or features/functionalities provided therein, data associated with other parties to a communication (e.g., their schedules, preferences, etc.), and the like. Additional illustrative examples of the use of context by the location-based address book component are provided below. 
     As shown, the functions  800  illustratively include filtering user contacts to identify those contacts who will be co-located with the user at a future time (as indicated by reference numeral  825 ); identifying user contacts from external sources ( 830 ); identifying organizational contacts for the geographic location to which the user will be traveling ( 835 ); surfacing user selectable options for various settings ( 840 ); providing a dynamically updated location-based address book ( 845 ); providing notifications when a new contact has been identified who will be co-located with the user at a future time ( 850 ); enabling a location-based address book or contact list to persist after the trip is completed ( 855 ) and providing and supporting other features and functionalities ( 860 ). The list of functions  800  is not intended to be exhaustive and other functions may be provided by the location-based address book component as may be needed for a particular implementation of the present location sharing. Moreover, not all the enumerated functions may be provided in any given implementation. 
     In some implementations, the location-based address book component  450  can be configured to interoperate with a personal digital assistant that is operable on the device  110 . As shown in  FIG. 8 , a personal digital assistant  910  can expose a variety of functions  900  which illustratively include interacting with the user  915  (through the natural language user interface and/or other user interfaces, for example); performing tasks  920  (e.g., making note of appointments in the user&#39;s calendar, sending messages and emails, etc.); providing services  925  (e.g., answering questions from the user, mapping directions to a destination, etc.); gathering information  930  (e.g., finding information requested by the user about a book or movie, locating the nearest Italian restaurant, etc.); operating the device  935  (e.g., setting preferences, adjusting screen brightness, turning wireless connections such as Wi-Fi and Bluetooth on and off, etc.); and performing various other functions  940 . The list of functions  900  is not intended to be exhaustive and other functions may be provided by the digital assistant as may be needed for a particular implementation of the present location-based address book. 
     In a similar manner as with the arrangement shown in  FIG. 7 , inputs to the digital assistant  910  can include user input  805 , data from internal sources  810 , data from external sources  815 , and contextual data  820 . 
       FIG. 9  is a conceptual diagram illustrating the generation of a location based address book. The location based address book  312  includes a list of people  314  that are associated with a geographic location  310  and a list of organizations  316  that are associated with the geographic location  310 . The list of people  314  can be filtered  306  from a more complete list of user contacts  302 . The more complete list of user contacts includes contacts associated with a variety of different locations. In some implementations, the more complete list of user contacts  302  is user-defined (i.e., each contact in the list has been selected for inclusion in the list by the user). In other implementations the more complete list of user contacts  302  may include contacts who have been obtained from the user&#39;s social graph, which may be maintained by one or more external social networking services  339 . The address book may be dynamically populated with such contacts without direct user intervention. 
     The list of organizational contacts  316  is not drawn from the list of user contacts  302 , but may be retrieved from a search engine  308  as being associated with both the location  310  and specific categories of services. For example, the search engine  308  provides contacts  318 ,  320 ,  322 , and  324  that are specific to “Orlando, Fla.” for the “Police,” “Hospital,” “Taxi,” and “Transit” categories of services. 
     The geographic location  310  may be a geographic location where a user of a device is expected to be during an upcoming specified period of time, possibly for business or leisure travel. In some implementations the list of people  314  that are associated with a geographic location  310  are also people who will be at that same location during at least a portion of that same period of time. The list of people may include people who reside or work at that location, but may also include people who will also be visiting that geographic location  310  for a limited period of time. 
     The list of people  314  may be obtained in any of a variety of different ways. For example, the location-based address book component  350  residing in whole or in part on the user&#39;s device may coordinate with the personal digital assistant component  910  (see  FIG. 8 ) to obtain contextual data  820  (see  FIG. 7 ) about the individuals in the list of user contacts  302 . Such contextual data may relate to the behavior (e.g., online activity) of the user contacts from which information can be extracted indicating that the contacts may be traveling to some geographic at a specified time in the future. 
     The contextual data can be obtained, for example, from any of the various inputs shown in  FIG. 7 . For instance, external sources of contextual data may include calendars that are maintained by the individuals in the list of user contacts  102 . Such calendars may reside on devices associated with those individuals or on an online calendar maintained by a service provider, for example. In the event that the calendars reside on another user&#39;s device, the calendars may be accessed, for example, using device-to-device communication (with notice to the other and the other user&#39;s consent). Other external sources of contextual data may include social networking services, various web sites and the like. 
     In the case of social networking services, the list of people  314  who will be at the geographic location  110  during a period of time that overlaps with the period of time during which the user will be at that location may be obtained not only from calendars, but also from other sources such as posts, check-ins, timelines, chats, tweets, tickers, blogs and so on. Of course, the location-based address book component  450  may aggregate data from any of the aforementioned illustrative sources, as well as other sources not mentioned above. 
     Contextual data also can be obtained from internal sources of data that may be reside on the user&#39;s device. Such data may be extracted, for example, from stored text messages, tweets, emails and other data associated with various applications that may reside on the user&#39;s device. 
     As previously mentioned, the contextual data may be used by the location-based address book component examine all the online activity of user contacts to determine if one or more of them will be traveling to specified location at some time in the future. For example, the location based address book component  450  (possibly in coordination with one or more other components such as the personal digital assistant  910 ) may determine that Mary has been spending time on travel websites searching for information about Los Angeles. This, coupled with additional contextual information gleaned from various sources, including possibly Mary&#39;s other online activities, may be used to determine that Mary is in fact planning an upcoming trip to Los Angeles. 
     A user interface (UI) may be associated with the location-based address book component  450  which exposes various features, controls and options associated with the component. For instance, the UI may allow the user to control how the location-based address book is presented to the user. By way of example, the UI may allow the user to control what information is to be included in the various entries of the location-based address book (e.g. physical and electronic addresses mobile phone numbers company affiliation, addresses or other contact information for the user when visiting the specified geographic location, if available.) As another illustrative example, the UI may allow the user to control whether a notification is to be surfaced to the display of the device when the location-based address book component identifies a new contact that is going to be added to the location-based address book.  FIG. 10  shows one example of a text string  340  that may be displayed by UI  350  on the device&#39;s start screen  330  when a contact is added in this manner. In some implementations such as shown in  FIG. 11  the UI  350  may also present a text string  345  to allow the user to choose whether the newly identified contact should be added to the location-based address book. 
       FIG. 12  shows a flowchart of an illustrative method  300  for generating a location-based address book or contact list. Unless specifically stated, the methods or steps shown in the flowchart below and described in the accompanying text are not constrained to a particular order or sequence. In addition, some of the methods or steps thereof can occur or be performed concurrently and not all the methods or steps have to be performed in a given implementation depending on the requirements of such implementation and some methods or steps may be optionally utilized. 
     In step  1005 , a UI can be exposed for a user to initiate the creation of location-based contact list. The UI may be incorporated into the UI exposed by a location-based address book component, although the process may be initiated by other components as well. The user uses the UI in step  1010  to provide the device with criteria to be used to generate a location-based contact list from among the user&#39;s various contacts. Among other things, the criteria may include the location(s) to which the user will be traveling and the date(s) on which the user will be visiting. In some implementations the user may specify whether the contacts to be searched are contacts stored in a local address book and/or a remotely located address book. Moreover, in some cases the user may also specify whether the contacts are to include contacts available through the user&#39;s social graph who the user has not directly entered into his or her address book. Other items that may be specified, for example, include whether any organizational contacts should be included who provide products and/or services at the specified location, and possibly what types of organizational contacts to include 
     In step  1015  the device can access the locally available and/or remotely located address book to obtain the names of the user&#39;s contacts. Next, in step  1020  the device collects contextual data concerning the user contacts. The contextual data may be obtained from internal sources such as locally stored applications, databases and the like. The contextual data also may be obtained from external sources such as external systems, databases and services. In step  1025  the device aggregates the various contextual data available to it and uses this data to identify those contacts (if any) who may be present at one of the locations specified by the user on any of the specified dates. In step  1030  the device then populates and stores a location-based contact list with the names of those user contacts who have been identified. In addition to the names of the contacts, the entries in the contact list may include additional information concerning the contacts. 
     Advantageously, the present location-based address book allows the user, and his or her device as well, to operate more efficiently. For example, the user does not need to search through large lists of contacts when attempting to find pertinent contacts while traveling. In addition, the use of a personal assistant component to identify contextually relevant information allows transmission bandwidth (and device power) to be efficiently utilized since only the information that is truly pertinent is provided to the user. Accordingly, the user does not need to employ a search engine to obtain information that may not be contextually relevant, which could consume excess bandwidth, time and power. 
       FIG. 13  is a simplified block diagram of an illustrative computer system  3200  such as a PC, client machine, or server with which the location-based address book component may be implemented. Computer system  3200  includes a processor  3205 , a system memory  3211 , and a system bus  3214  that couples various system components including the system memory  3211  to the processor  3205 . The system bus  3214  may be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, or a local bus using any of a variety of bus architectures. The system memory  3211  includes read only memory (ROM)  3217  and random access memory (RAM)  3221 . A basic input/output system (BIOS)  3225 , containing the basic routines that help to transfer information between elements within the computer system  3200 , such as during startup, is stored in ROM  3217 . The computer system  3200  may further include a hard disk drive  3228  for reading from and writing to an internally disposed hard disk (not shown), a magnetic disk drive  3230  for reading from or writing to a removable magnetic disk  3233  (e.g., a floppy disk), and an optical disk drive  3238  for reading from or writing to a removable optical disk  3243  such as a CD (compact disc), DVD (digital versatile disc), or other optical media. The hard disk drive  3228 , magnetic disk drive  3230 , and optical disk drive  3238  are connected to the system bus  3214  by a hard disk drive interface  3246 , a magnetic disk drive interface  3249 , and an optical drive interface  3252 , respectively. The drives and their associated computer-readable storage media provide non-volatile storage of computer-readable instructions, data structures, program modules, and other data for the computer system  3200 . Although this illustrative example includes a hard disk, a removable magnetic disk  3233 , and a removable optical disk  3243 , other types of computer-readable storage media which can store data that is accessible by a computer such as magnetic cassettes, Flash memory cards, digital video disks, data cartridges, random access memories (RAMs), read only memories (ROMs), and the like may also be used in some applications of the present real-time sharing during a phone call. In addition, as used herein, the term computer-readable storage media includes one or more instances of a media type (e.g., one or more magnetic disks, one or more CDs, etc.). For purposes of this specification and the claims, the phrase “computer-readable storage media” and variations thereof, does not include waves, signals, and/or other transitory and/or intangible communication media. 
     A number of program modules may be stored on the hard disk, magnetic disk  3233 , optical disk  3243 , ROM  3217 , or RAM  3221 , including an operating system  3255 , one or more application programs  3257 , other program modules  3260 , and program data  3263 . A user may enter commands and information into the computer system  3200  through input devices such as a keyboard  3266  and pointing device  3268  such as a mouse. Other input devices (not shown) may include a microphone, joystick, game pad, satellite dish, scanner, trackball, touchpad, touch screen, touch-sensitive device, voice-command module or device, user motion or user gesture capture device, or the like. These and other input devices are often connected to the processor  3205  through a serial port interface  3271  that is coupled to the system bus  3214 , but may be connected by other interfaces, such as a parallel port, game port, or universal serial bus (USB).

     It may be appreciated that the software components described herein may, when loaded into the CPU  3302  and executed, transform the CPU  3302  and the overall architecture  3300  from a general-purpose computing system into a special-purpose computing system customized to facilitate the functionality presented herein. The CPU  3302  may be constructed from any number of transistors or other discrete circuit elements, which may individually or collectively assume any number of states. More specifically, the CPU  3302  may operate as a finite-state machine, in response to executable instructions contained within the software modules disclosed herein. These computer-executable instructions may transform the CPU  3302  by specifying how the CPU  3302  transitions between states, thereby transforming the transistors or other discrete hardware elements constituting the CPU  3302 . 
     Encoding the software modules presented herein also may transform the physical structure of the computer-readable storage media presented herein. The specific transformation of physical structure may depend on various factors, in different implementations of this description. Examples of such factors may include, but are not limited to, the technology used to implement the computer-readable storage media, whether the computer-readable storage media is characterized as primary or secondary storage, and the like. For example, if the computer-readable storage media is implemented as semiconductor-based memory, the software disclosed herein may be encoded on the computer-readable storage media by transforming the physical state of the semiconductor memory. For example, the software may transform the state of transistors, capacitors, or other discrete circuit elements constituting the semiconductor memory. The software also may transform the physical state of such components in order to store data thereupon. 
     As another example, the computer-readable storage media disclosed herein may be implemented using magnetic or optical technology. In such implementations, the software presented herein may transform the physical state of magnetic or optical media, when the software is encoded therein. These transformations may include altering the magnetic characteristics of particular locations within given magnetic media. These transformations also may include altering the physical features or characteristics of particular locations within given optical media to change the optical characteristics of those locations. Other transformations of physical media are possible without departing from the scope and spirit of the present description, with the foregoing examples provided only to facilitate this discussion. 
     In light of the above, it may be appreciated that many types of physical transformations take place in the architecture  3300  in order to store and execute the software components presented herein. It may also be appreciated that the architecture  3300  may include other types of computing devices, including handheld computers, embedded computer systems, smartphones, PDAs, and other types of computing devices known to those skilled in the art.
