Abstract: Switching real-time data stream connections between network nodes sharing a virtual area is described. In one aspect, the switching involves storing a virtual area specification. The virtual area specification includes a description of one or more switching rules each defining a respective connection between sources of a respective real-time data stream type and sinks of the real-time data stream type in terms of positions in the virtual area. Real-time data stream connections are established between network nodes associated with respective objects each of which is associated with at least one of a source and a sink of one or more of the real-time data stream types. The real-time data stream connections are established based on the one or more switching rules, the respective sources and sinks associated with the objects, and respective positions of the objects in the virtual area.

Abstract: Examples of interface systems and methods for voice-based interaction 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: 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: A network communications environment has advanced interaction management functionality that enables the opportunities for users to interact with one another to be expanded beyond the opportunities that exist with closed interaction management approaches while still providing reasonable privacy and security protections that are not available with open interaction management approaches. The advanced interaction management functionality also encourages the proliferation of trust-based interactions.

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 nodes. Capability-based permissions checks can be performed against communicant capabilities with wildcarded attribute fields.

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: Examples of systems and methods for bridging virtual and physical spaces are described. In some of these examples, a particular communicant's real world state drives changes in one or more of the communications connections, virtual state, and communications interface of the particular communicant or another communicant.

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: 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.
