DETAILED DESCRIPTION
FIG. 1 shows an example local expert session system 140. The local expert session system 140 is an example of a system implemented as computer programs on one or more computers in one or more locations, in which the systems, components, and techniques described below can be implemented.
A user can interact with the local expert session system 140 using a user device 130 through a data communication network 102. The network 102 enables data communication between multiple electronic devices. Users can access content, provide content, exchange information, and participate in local expert sessions by use of the devices and systems that can communicate with each other over the network 102. The network 102 can include, for example, a local area network (LAN), e.g., a Wi-Fi network, a cellular phone network, a wide area network (WAN), e.g., the Internet, or a combination of them.
A user device 130 is an electronic device, or collection of devices, that is under the control of a user and is capable of interacting with the local expert session system 140 over the network 102. Example user devices 130 include personal computers 132, mobile communication devices 134, and other devices that can send and receive data over the network 102. A user device 130 is typically configured with a user application, e.g., a web browser, that sends and receives data over the network 102, generally in response to user actions. The user application can enable a user to display and interact with text, images, videos, music and other content, which can be located on a web page on the World Wide Web or a local area network.
The local expert session system 140 allows people to organize, request, and participate in local expert sessions. In a local expert session, one person, the local expert, offers advice or assistance to another person while viewing video captured by a session accessory 160 worn by the other person. The local expert is a person who has been recognized by the system 140 as an expert on the geographic area in which the other person is located or on a point of interest near to the location of the other person. During the session, the person in need of advice or assistance can play an active role, e.g., by asking questions, and information can go in both directions during the session. The term “local expert session” may thus refer to such an interaction, the period of interaction, or a recording of such an interaction, as the context requires.
In particular, the local expert session system 140 allows users having a session accessory 160 to receive assistance from local experts who are viewing a video feed of video captured by the session accessory 160 on user devices 130.
A local expert is a user who has registered with the local expert session system 140 in order to be accepted by the local expert session system 140 to participate in local expert sessions that are relevant to a specified geographic location or region, to a specific site or facility, or to a particular point of interest, i.e., to provide assistance to users located there. For example, a user can register as a local expert for the town of Lodi, Calif. or for the Taj Mahal. Local expert sessions are described in more detail below with reference to FIG. 2.
In general, session accessories 160 are devices that a person can use to participate in sessions with the local expert session system 140. Session accessories 160 will typically be portable, personal, multimode, e.g., audio and video, electronic devices. Session accessories 160 can be, for example, wearable computing devices that include a camera and a microphone that may be worn on a user's person. For example, a session accessory 160 can include a hat camera system that includes a camera mounted on a hat, e.g., on the brim of a hat, which can connect wirelessly to the local expert session system 140, e.g., by connecting wirelessly to a mobile computing system, e.g., a mobile phone or other mobile device, that can connect to the local expert session system 140 or by connecting to the local expert session system 140 over a Wi-Fi network. An example hat camera system is described in more detail in U.S. Patent Application No. 61/781,506, entitled “Wearable Camera Systems” and filed on Mar. 14, 2013. Session accessories 160 can also include other camera systems that are worn by a person and that provide point-of-view video data, for example, a helmet-mounted camera. Generally, a session accessory 160 is a system that includes one or more of an audio input device 160-1, a video input device 160-2, a display device 160-3, and optionally other input devices, e.g., for text or gesture input.
A session accessory 160 may be used during a local expert session to broadcast video taken from the point of view of a user wearing the session accessory 160 to the local expert that is participating in the session. In implementations where the session accessory 160 connects wirelessly to a mobile device, the mobile device can be configured to communicate with the local expert session system 140 through an application executing on the mobile device. Optionally, the zoom and position of the video input device 160-2 may be controllable by the local expert that is participating in a session by submitting an input to the local expert session system 140. For example, the local expert may be able to adjust the zoom or the position of the video input device in order to have a better view of a street sign or other landmark while the user in need of assistance is driving.
FIG. 2 is a flow diagram of an example process 200 for initiating a local expert session. For convenience, the process 200 will be described as being performed by a system of one or more computers located in one or more locations. For example, a local expert session system, e.g., the local expert session system 140 of FIG. 1, appropriately programmed, can perform the process 200.
The system receives a request to initiate a local expert session from a user (step 202). For example, the user may submit a request using a session accessory or using a separate user device. In some implementations, the user can submit a request by speaking a pre-determined voice command that is recognized by the session accessory or other user device and causes the session accessory or other user device to submit a request to the system. The request identifies a physical location of the user. For example, the user may manually enter the location through a user interface provided by the system or the system can obtain data identifying the user's location, e.g., by receiving coordinates from a Global Positioning System (GPS) of the session accessory or other user device being used by the user or by otherwise determining the location of the user's session accessory or mobile device using conventional techniques.
The system identifies available local experts in response to the request (step 204). The local experts are users that have been accepted by the system to offer local expert sessions in the physical location identified in the request. The system may determine which local experts of the local experts registered with the system for the physical location are available when the request is received in any of a variety of ways.
For example, the system can make the determination based on availability data received from the local experts that identifies time periods during which the local experts are available to participate in local expert sessions. As another example, the system can make the determination based on which local experts are currently logged in to the system or based on data that identifies a current presence status of the local experts, i.e., active, idle, busy, or offline.
The system selects an available local expert (step 206). In some implementations, the system ranks the available local experts, provides a user interface for presentation to the user that identifies available local experts in an order according to the ranking, and receives input from the user selecting one of the local experts.
However, in some circumstances, e.g., while driving, it may not be convenient for a user to select from identified local experts. Therefore, in some implementations, the system ranks the available local experts and selects a candidate local expert based on the ranking, i.e., without further user input. The system can rank the available local experts based on any of a variety of factors.
For example, the system can rank the available local experts based at least in part on ratings provided from previous users that have participated in a local expert session with the local expert. As another example, the system can rank the available local experts based at least in part on a count of local expert sessions participated in by the local expert. As another example, the system can rank the available local experts based at least in part on the amount of money charged by the local experts for participating in the session. As another example, the system can rank the available local experts based at least in part on one or more user-specific factors, e.g., whether the local expert has previously participated in a local expert session with the user or whether the local expert is in the user's social network.
The system initiates a local expert session between the selected local expert and the user (step 208). That is, the system provides a live feed of video captured by the session accessory worn by the user to a user device for presentation to the local expert and establishes audio communication between the user and the local expert. During the session, the local expert can answer questions, provide advice, or otherwise assist the user by providing information that is relevant to the location but that is not known by the user. As described above, during the session, the local expert may be able to adjust the zoom or the position of a video input device included in the session accessory worn by the user in order to better assist the user during the session. That is, the system may receive a request to adjust the zoom or the position of the video input device and transmit instructions to the session input device that cause the session accessory to adjust the zoom or position of the device accordingly.
In some implementations, instead of or in addition to establishing audio communication between the local expert and the user, the system may enable communication using a different means, e.g., using text messages, e.g., Short Message Service (SMS) messages. Similarly, instead of or in addition to providing the live video captured by the user's session accessory to the local expert, the system may provide other signals to the local expert, e.g., the location of the user as captured by the session accessory or temperature readings captured by the session accessory.
While the above description describes local expert sessions as connecting a user with an expert that is knowledgeable about an area in which the user is currently located, in some implementations, users may be able to initiate local expert sessions with local experts that are experts on other locations of interest to the user, i.e., to specify a location that is different from the user's current location. For example, a user may be able to input a destination and be connected to an expert that can help the user select a hotel for an upcoming vacation to the destination or to select an apartment to rent before the user moves to the destination.
Embodiments of the subject matter and the operations described in this specification can be implemented in digital electronic circuitry, or in computer software, firmware, or hardware, including the structures disclosed in this specification and their structural equivalents, or in combinations of one or more of them. Embodiments of the subject matter described in this specification can be implemented as one or more computer programs, i.e., one or more modules of computer program instructions, encoded on computer storage medium for execution by, or to control the operation of, data processing apparatus. Alternatively or in addition, the program instructions can be encoded on an artificially-generated propagated signal, e.g., a machine-generated electrical, optical, or electromagnetic signal, that is generated to encode information for transmission to suitable receiver apparatus for execution by a data processing apparatus. A computer storage medium can be, or be included in, a computer-readable storage device, a computer-readable storage substrate, a random or serial access memory array or device, or a combination of one or more of them. Moreover, while a computer storage medium is not a propagated signal, a computer storage medium can be a source or destination of computer program instructions encoded in an artificially-generated propagated signal. The computer storage medium can also be, or be included in, one or more separate physical components or media.
The operations described in this specification can be implemented as operations performed by a data processing apparatus on data stored on one or more computer-readable storage devices or received from other sources.
