  • TRACKING APPROACHING OR HOVERING OBJECTS FOR USER-INTERFACES
    Publication number: 20150160753
    Abstract: An architecture is described that can utilize photo-sensors embedded in a substantially transparent layer of a UI display for tracking objects that approach or hover over the UI display. The photo-sensors can be configured to detect light of certain wavelengths (e.g., visible light, infrared light) that are propagated toward the UI display, while ignoring light emanating from the UI display when displaying content. Accordingly, by examining various characteristics of the incoming light such as intensity, the architecture can identify a location of a shadow incident upon the display caused by an approaching or hovering selector object blocking portions of incoming light. Additionally or alternatively, the architecture can identify a location of higher intensity for light emanating from the selector object.

  • METHOD AND SYSTEM FOR DETERMINING SUBSCRIBER DEMAND FOR MULTIMEDIA CONTENT
    Publication number: 20150150030
    Abstract: A method of determining demand for multimedia content in a multimedia provider network includes receiving a content demand statistics (CDS) request from a client application where the request identifies a subscriber set. Responsive to the CDS request, selected CDS data is retrieved from a CDS subsystem. The CDS data is indicative of demand for multimedia content among subscribers in the subscriber set. The retrieved CDS data is delivered to the client application. The selected data may be selected from past data, present data, and future data. The CDS request indicates a set of buddy subscribers and the messaging server retrieves CDS data associated with the buddy subscribers. A security subsystem may be accessed and to determine, prior to retrieving CDS data for a particular buddy subscriber, whether the particular buddy subscriber has authorized the requesting subscriber.

  • Securing uniform resource identifier information for multimedia calls
    Patent number: 8948057
    Abstract: A session request from a first subscriber is received at a first network component of a packet-based network. The session request comprises a request to establish a communications session between the first subscriber and a second subscriber. In the event the session request originated in a trusted network, the first network component permits access to unique resource identifier (URI) information associated with the second subscriber for use in establishing the communications session via the packet-based network. In the event the session request did not originate in a trusted network and in response to determining a security configuration associated with the second subscriber allows the first subscriber to access the URI information under the circumstances, the first network component permits access to the URI information for use in establishing the communications session via the packet-based network.
