Abstract: In a network communications environment supporting realtime communications between respective network nodes of a user and other communicants in virtual areas each of which is associated with its own respective set of communicant members, a graphical user interface is provided in connection with the user's network node. The graphical user interface includes controls for establishing presence in respective ones of the virtual areas, managing realtime communications with other communicants in respective ones of the virtual areas, and presenting different views of communicants associated with the network communications environment.

Abstract: A pervasive realtime framework supports the execution of realtime software applications with high-level functions that significantly reduce the effort and time needed to develop realtime software applications in a new operating environment paradigm in which realtime connections between network nodes are pervasive. The pervasive realtime framework handles the complex tasks of connecting to communicants, virtual areas, and other network resources, as well as switching those connections in response to user inputs and thereby enables software application developers to focus on developing high-level realtime software application functionality.

Abstract: Examples of systems and methods for voice-based navigation in one or more virtual areas that define respective persistent virtual communication contexts are described. These examples enable communicants to use voice commands to, for example, search for communication opportunities in the different virtual communication contexts, enter specific ones of the virtual communication contexts, and bring other communicants into specific ones of the virtual communication contexts. In this way, these examples allow communicants to exploit the communication opportunities that are available in virtual areas, even when hands-based or visual methods of interfacing with the virtual areas are not available.

Abstract: Improved systems and methods for navigating and interacting in virtual communication environments. At least some of these systems and methods provide a framework that includes one or more virtual areas and supports realtime communications between the communicants. At least some of these systems and methods provide an interface that includes navigation controls that enable a user to navigate virtual areas and interaction controls that enable the user to interact with other communicants in the one or more virtual areas.

Abstract: A graphical user interface is displayed. The graphical user interface includes at least one communication control for managing communications with other network nodes and at least one browser control for navigating to different network resource addresses. Human perceptible realtime output is generated from realtime communication data relating to a realtime communication session with at least one other client network node. In the process of generating of at least some of the human perceptible realtime output, operation of the client network node is managed based on at least one performance target. In the graphical user interface, a graphical representation of a network resource identified in connection with the browser control is displayed.

Abstract: Apparatus transmits an identifier for association with a virtual area by an administering network service, generates output data from human perceptible stimulus in a physical space, transmits the output data in connection with the virtual area, receives input data associated with the virtual area, and generates human perceptible stimulus in the physical space from the input data. A persistent association is created between the apparatus and a virtual area. A respective presence is established in the virtual area for a communicant operating a client network node connected to the virtual area. A respective connection between each active pair of complementary sources and sinks of the client network node and the apparatus are administered in association with the virtual area. A client network node displays a graphical user interface, establishes the administered connections, and presents interaction controls associated with the object for interacting with communicants in the physical space.

Abstract: Apparatus and methods of managing a virtual area based on communicant capabilities are described. The communicant capabilities are updated based on rules in response to events in the virtual area. An action by one communicant can affect the capabilities of another communicant. Communicant capabilities can be stored in respective server-side proxies and the virtual area can be managed without transmitting any of the capabilities to the communicants' client network nodes. Capability-based permissions checks can be performed against communicant capabilities with wildcarded attribute fields.

Abstract: A realtime kernel supports realtime communications between communicants operating on respective network nodes. The realtime kernel handles the complex tasks of connecting to communicants, virtual areas, and other network resources, switching those connections in response to user inputs, and mixing realtime data streams. The realtime kernel enables developers to focus on developing high-level communications functionality instead of low-level plumbing code. The realtime kernel imposes relatively low computational resource requirements so that realtime communications performance can be achieved using a wide range of computing devices and network connections that currently are available.

Abstract: Realtime communications between communicants in a virtual area are administered. Assemblies of copresent communicants in the virtual area are detected. For each of respective ones of the detected assemblies, a respective meeting object linked to information relating to communicant interactions in the assembly is generated. Respective meeting summary data is determined based on the information linked to selected ones of the meeting objects meeting objects. The determined meeting summary data is transmitted to a network node for display. A visualization of summaries of respective assemblies of copresent communicants in the virtual area is presented on a display.

Abstract: In association with a virtual area, a first network connection is established with a first network node present in the virtual area and a second network connection is established with a second network node present in the virtual area. Based on stream routing instructions, a stream router is created between the first network node and the second network node. The stream router includes a directed graph of processing elements operable to receive network data, process the received network data, and output the processed network data. On the first network connection, an input data stream derived from output data generated by the first network node is received in association with the virtual area. The input data stream is processed through the stream router to produce an output data stream. On the second network connection, the output data stream is sent to the second network node.
