Abstract: Techniques for snapshot capture for a communication session are described. According to various embodiments, a communication session is established that includes a video feed that is streamed between devices involved in the communication session. The video feed is sampled to extract still images (e.g., frames) from the video feed that include images of a particular participant in the communication session. A snapshot is then selected from the images based on one or more selection criteria, such as an image score for the snapshot. Should a quality of the video feed fall below an acceptable video quality threshold during the communication session, the snapshot is used in place of the video feed for a visual representation of the participant during the communication session.

Abstract: A system to determine viewer attention to presented content. Markers are applied to a presentation. Head orientation information is received from a body mounted camera worn by a viewer and is used to determine a sequence of head orientations of the viewer. The sequence of head orientations is associated with an identifier of the viewer and a corresponding sequence of first time stamps. A sequence of images is captured by the body mounted camera worn by the viewer. The sequence of images is associated with an identifier of the viewer and the body mounted camera and a corresponding sequence of second time stamps. Respective members of the sequences of images and head orientations are associated, and the presentation content is identified by evaluating information from visible markers in the captured sequence of images. Viewer attention to different elements can then be determined.

In one implementation, the system includes a monitoring device positioned to monitor one or more biometric parameters of the user, and saving the biometric data on a server for processing.

Abstract: Techniques allow seamless transitioning of a mesh-based videoconference to a bridged videoconference. Criteria are defined for use in a triggering point function that may be evaluated to determine whether to make the transition. Escalation logic in an escalation manager may be used to manage the transition, allowing some participants to connect via a multipoint control unit, which is in turn a participant in the mesh-based videoconference, with the escalation manager relaying media streams from the mesh-connected participants. The mesh-connected participants may then drop their mesh connections without disruption to the videoconference. Escalation logic in the endpoints may be used as an alternate to an escalation manager unit.

Abstract: Various systems and associated methods for tracking chats, text messages, and other user interactions. The process generates at least one identifier, distributes at least one identifier to at least one system, uses the at least one identifier to associate interactions with network-based content across different entities, whereby at least one interaction is anonymous. The method involves receiving a request sent to a database stored on a computer readable medium in response to online activity and any collected or known user information, creating a record thereof in response to the request, generating an identifier associated therewith, generating a code corresponding thereto, and using the identifier to associate an incoming text message, chat, resulting financial transactions, follow-on activities, etc. with associated online activity and user information. The association happens through remote communication with a system that receives and sends the incoming text message or chat requests.
