  • Publication number: 20240077985
    Abstract: An electronic device may include one or more sensors that capture sensor data for a physical environment around the electronic device. The sensor data may be used to determine a scene understanding data set for an extended reality environment including the electronic device. The scene understanding data set may include information such as spatial information, information regarding physical objects in the extended reality environment, and information regarding virtual objects in the extended reality environment. When providing scene understanding data to one or more applications running on the electronic device, spatial and/or temporal restrictions may be applied to the scene understanding data set. Scene understanding data that is associated with locations within a boundary and that is associated with times after a cutoff time may be provided to an application.

  • Patent number: 9325646
    Abstract: One or more first devices may receive, from a second device, program information as part of a request to provide a contextual message, associated with particular content corresponding to the program information, to a third device. The program information may identify a time, a geographic location, and a television channel identifier associated with the particular content. The one or more devices may cause the particular content to be identified based on a fingerprint of the particular content; receive the contextual message that was identified based on the fingerprint; provide the contextual message to the third device; and provide, for storage in a content schedule, information identifying the particular content, a time period during which the particular content is broadcasted, the geographic location, and the television channel identifier. The content schedule may be used to identify the particular content after the particular content has been initially identified based on the fingerprint.
