Abstract: Systems and methods for controlling media playback via physical tokens (e.g., items of media content such as photographs) are disclosed. A media playback system can include an audio playback device and a control device. The control device includes a sensor configured to sense a tag of the physical token. The control device can obtain data by sensing the tag of the physical token via the sensor. Based on the obtained data, the control device transmits a request for media content to one or more remote computing devices associated with a media content service, and causes playback of the requested media content via the audio playback device. Additionally or alternatively, spatial audio content can be generated and played back based on a media item characteristic obtained via the sensor data.

Abstract: An example system includes one or more resource managers forming a federation of resources, at least one resource manager being associated with one or more resources; a federation hub for receiving local resource information from each of the one or more resource managers, wherein the federation hub aggregates the local resource information from each of the one or more resource managers and provides an aggregated view of all resources of the federation; and a bylaw guardian for determining compliance of each of the one or more resource managers to requirements of the federation.
