Some embodiments of the client device 106 or client device 109 may be mobile or portable devices.
The client device 106 may be configured to execute various applications such as a topic assistance application 127 and a location provider component 130. The client device 106 may be configured to execute other applications such as, for example, browsers, email applications, instant message applications, navigation applications, and/or other applications. The topic assistance application 127 may be executed in the client device 106 to facilitate a customer contacting a topic specialist in order to obtain assistance or more information about a particular topic. To this end, the topic assistance application 127 may interact with the call center server 121. The topic assistance application 127 may be implemented as a standalone application or may be executed in the context of a browser, as should be appreciated.
The location provider component 130 is executed in the client device 106 to provide the current location of the client device 106. Various technologies may be used to implement the location provider component 130, for example, a global positioning system (GPS), an assisted global positioning system (A-GPS), a wireless local area network (WiFi) positioning system, or a wireless network (WiMax) positioning system.

The client device 109 may be configured to execute various applications such as a call agent application 133 and/or other applications. The call agent application 133 may be executed in the client device 109 to answer phone calls that originate from customers. To this end, the call agent application 133 may interact with the call center server 121. During the call, the call agent application 133 may provide the topic specialist with information that identifies the topic of the call. The client device 109 may be configured to execute other applications such as, for example, browsers, email applications, instant message applications, navigation applications, and/or other applications.
Next, a general description of the operation of the various components of the networked environment 100 in an example use scenario is provided. To begin, a mobile customer uses the topic assistance application 127 to make a phone call in order to obtain assistance for a particular topic. The customer is not required to identify the topic. Instead, the topic of interest is derived from the mobile customer's current physical location. To this end, in response to a request for assistance from the mobile customer, the topic assistance application 127 obtains the mobile customer's current geographic location from the location provider component 130. The current geographic location is more specific than an area code, and in some embodiments may be more specific than a street address. In particular, the current geographic location may be accurate enough to place the customer within a structure or building such as a store, and may even be accurate enough to place the customer within a particular department or aisle within a store.
These geographic locations are each associated with a topic or subject matter area. As one example, a location corresponding to a store department is associated with the category of items or products offered in that department. As another example, a location corresponding to an aisle within a store is associated with the category or categories of items or products displayed on that aisle. Automatically deriving the item category from the customer's location reduces the amount of information which the customer must provide in order to obtain assistance on that item category.
As yet another example, if the location is a city neighborhood, the associated topic may be the neighborhood itself. By automatically deriving the topic from the customer's location, the topic assistance application 127 can facilitate the customer obtaining more information about the neighborhood by talking to a specialist, without even knowing the name of the neighborhood.
As yet another example, if the location is a particular city block, the associated topic may be businesses, stores, or points of interest located on that block. By automatically deriving the topic from the customer's location, the topic assistance application 127 can facilitate the customer obtaining more information from a specialist who is knowledgeable about those points of interest.
The topic assistance application 127 then sends a call request, which includes the customer's current location, to the call center server 121 executing on the computing device 103. The call center server 121 uses the services of the specialist locator module 124 to find a particular person who has knowledge about a topic, where the topic has a predefined association with the customer's geographic location. The topic specialist returned by the specialist locator module 124 may be at the same location as the customer, or may be located remotely with respect to the customer. If the customer location is a business, the topic specialist may be an employee of the business, or may be a third party provider. The call center server 121 then fulfills the customer's request for assistance by routing the phone call to the identified specialist. The topic may be an item such as a product or product category, so that the topic specialist can be viewed as an item specialist or product specialist.
In some embodiments, the specialist locator module 124 maps directly from the geographic location to the contact phone number for the topic specialist. In other embodiments, the specialist locator module 124 maps from the geographic location to the topic area, and from the topic area to a contact phone number for a specialist in that topic area. In still other embodiments, the specialist locator module 124 maps from the geographic location to the topic area and the call center server 121 maps the topic area to a specialist and a phone number for the specialist. In such embodiments, the mapping function is distributed between the specialist locator module 124 and the call center server 121.
Once the call between the mobile user and the topic specialist is established, the call proceeds in the conventional fashion. The phone call may include audio, video, multimedia, or a combination thereof. The video portion of the call may utilize a camera or other video capture device located in the mobile client device 106, or may utilize cameras or other video capture devices installed at the mobile customer's current location and connected to the network 112. For example, if the customer is in a store, network-accessible cameras may be installed along various aisles of the store, or in various store departments. If the customer is outside on a street, the call may use various network-accessible cameras on the street.
The call may include, or be associated with, data other than audio or video. For example, the topic specialist may send data to the mobile client device 106, for example in the form of a network page. In this manner, the topic specialist can provide information about a product during the call.
Turning now to FIG. 2, shown is a flowchart that provides one example of the operation of a portion of the topic assistance application 127 according to various embodiments. It is understood that the flowchart of FIG. 2 provides merely an example of the many different types of functional arrangements that may be employed to implement the operation of the portion of the topic assistance application 127 as described herein. As an alternative, the flowchart of FIG. 2 may be viewed as depicting an example of steps of a method implemented in the client device 106 (FIG. 1) according to one or more embodiments.
Beginning at box 203, the topic assistance application 127 receives, from a user of the client device 106, a request to contact a topic specialist. The contact request is not required to identify the topic, because the topic is instead derived from the current location of the mobile client device 106. To this end, at box 206 the topic assistance application 127 obtains, from the location provider component 130 executing on the client device 106, the current location of the client device 106. At box 209, the topic assistance application 127 sends a call initiation request to the call center server 121. The request includes the geographic location, but is not required to include the phone number of the callee. In some embodiments, the request also includes a topic identifier.
In response to the call initiation request, the call center server 121 routes the call to a topic specialist who can provide assistance to the user. At box 212, the topic assistance application 127 receives from the call center server 121 a notification that the call to the topic specialist has been established. The notification may include information such as the name, credentials, qualifications, and/or business affiliation of the specialist, Next, at box 215, the client device 106 handles the call by sending audio and/or video to the topic specialist, and by receiving audio and/or video from the topic specialist. Finally, at box 218 the call is terminated at the direction of either the customer or the topic specialist. The process of FIG. 2 is then complete.
In the embodiment described in connection with FIG. 2, an appropriate topic specialist is determined based on the customer's geographic location, for example, the current location of a mobile customer. In another embodiment, an application executing on a client device provides a product identifier to the topic assistance application 127, and the product identifier is mapped to a topic and then to a topic specialist. For example, the product bar code may be used as a product identifier. The bar code may be directly readable by the client device, or the customer may input the bar code manually. Other types of product identifiers may also be used, such as stock-keeping units (SKUs), serial numbers, etc.
With reference now to FIG. 3, shown is a flowchart that provides one example of the operation of a portion of the call center server 121 according to various embodiments. It is understood that the flowchart of FIG. 2 provides merely an example of the many different types of functional arrangements that may be employed to implement the operation of the portion of the call center server 121 as described herein. As an alternative, the flowchart of FIG. 2 may be viewed as depicting an example of steps of a method implemented in the computing device 103 (FIG. 1) according to one or more embodiments.
Beginning at box 303, the call center server 121 receives a call request from the topic assistance application 127 executing on a client device 106. The call request includes the current location of the client device 106. As discussed above, associations between geographic locations and topics, and/or between geographic locations and topic specialists, are stored in the specialist listing 118. At box 306, the call center server 121 uses the services of specialist locator module 124 to identify a topic specialist based on the mobile customer's geographic location. Next, at box 309, the call center server 121 routes the call from the client device 106 to the phone number of the identified topic specialist. At box 312, the call center server 121 notifies the topic assistance application 127 that the call has been established. At some later point in time, at box 315 the call is terminated at the direction of either the mobile customer or the topic specialist. The process of FIG. 3 is then complete.
In the embodiments described above, the mapping between the current geographic location of the client device 106 and the appropriate topic specialist for the phone call is performed by the call center server 121. In other embodiments, the client device 106 performs this mapping locally. In some of these embodiments, the client device 106 then establishes the phone call without the assistance of the call center server 121, using for example, a VoIP service to connect to the client device 109 and thus to communicate with the topic specialist.
Moving on to FIG. 4, shown is a schematic block diagram of the computing device 103 according to an embodiment of the present disclosure. The computing device 103 includes at least one processor circuit, for example, having a processor 403 and a memory 406, both of which are coupled to a local interface 409.
