Abstract: A processing apparatus including one or more processors and memory determines a first context of a first user at a first location in a physical space based on sensor measurements from one or more sensors of a set of one or more devices coupled to the first user and detects movement of the first user to a second location in the physical space based on sensor measurements from one or more sensors of the devices. The processing apparatus determines a second context of the first user at the second location based on sensor measurements from one or more sensors of the devices and generates, based on the first context, the second context, and the movement of the user from the first location to the second location, a first mapping of the physical space that includes information corresponding to a spatial relationship between the first context and the second context.

The processing apparatus determines device context information for the respective device based on the one or more sensor measurements and the one or more system signals and adjusts operation of the device in accordance with the device context information.

Abstract: A computer system stores calibration information corresponding to respective sets of sensor measurements associated with respective operating environments. After storing, in a first data structure, calibration information for a first operating environment, the system determines a current operating environment of the device. When the current operating environment of the device is consistent with the first operating environment and the calibration information for the first operating environment meets predefined measurement diversity criteria, the system calibrates at least one sensor for the first operating environment using the stored calibration information for the first operating environment. When the current operating environment of the device is inconsistent with the first operating environment, the system excludes the stored calibration information for the first operating environment when calibrating one or more sensors for the current operating environment.

Abstract: A system and method for determining an attitude of a device undergoing dynamic acceleration is provided. A first attitude measurement may be calculated based on a magnetic field measurement received from a magnetometer of the device and a first acceleration measurement received from a first accelerometer of the device. A second attitude measurement can be calculated based on the magnetic field measurement received from the magnetometer and a second acceleration measurement received from a second accelerometer of the device. A correction factor, calculated based on a difference between the two attitude measurements, can be applied to the first attitude measurement to produce a corrected device attitude measurement. The device can be a headset having two sets of in-the-ear and behind-the-ear microphones, a digital signal processor, and a communications interface. The device may comprise two hearing aids, each having multiple microphones, configured to wirelessly intercommunicate.

Abstract: A computer system having one or more processors and memory receives data corresponding to a device-selection command performed at a remote control, where the remote control is configured to provide remote-control commands to a plurality of devices. In response to receiving the data corresponding to the device-selection command, the computer system selects one of the devices as a selected device in accordance with information indicating that the remote control was pointed at a proxy for the selected device at the time that the device-selection command was performed at the remote control, where the proxy for the selected device is at a different location than the selected device. The computer system also generates a respective remote-control command for the selected device, where the respective remote-control command will, when received by the selected device, cause the selected device to perform a predefined operation that corresponds to the respective remote-control command.
