Context information exchange over a personal area network (patent application)

Devices connected via a Personal Area Network (PAN) exchange context information and coordinate context changes. The exchanged context information may include, e.g., an indication that a given PAN device has detected a context change. Additionally or alternatively, the exchanged context information may include sensor data obtained by the respective devices in the PAN, and one or more of the PAN devices may detect a content change based on the exchanged sensor data. For example, a given PAN device may detect a context change based on sensor data obtained via one or more sensors of the given device. As another example, the given device may detect a context change based on sensor data received from a second device in a PAN, the received sensor data in turn having been obtained by a second-device sensor of the second device.
