Abstract:
An electronic device with one or more processors and memory detects a button press of a respective button of a plurality of buttons that include a first button that corresponds to a first type of operation and a second button that corresponds to a second type of operation. The device determines, in conjunction with detecting the button press, a rolling gesture metric corresponding to performance of a rolling gesture comprising rotation about a longitudinal axis of the electronic device. After determining the rolling gesture metric, when the respective button is the first button, the device initiates performance, in a respective user interface, of an operation of the first type in accordance with the rolling gesture metric and when the respective button is the second button, the device initiates performance, in the respective user interface, of an operation of the second type in accordance with the rolling gesture metric.
Abstract:
A system and a method for determining an attitude of a device undergoing dynamic acceleration is presented. A first attitude measurement is 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 is calculated based on the magnetic field measurement received from the magnetometer of the device and a second acceleration measurement received from a second accelerometer of the device. A correction factor is calculated based at least in part on a difference of the first attitude measurement and the second attitude measurement. The correction factor is then applied to the first attitude measurement to produce a corrected attitude measurement for the device.

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 processing apparatus including one or more processors and memory obtains one or more sensor measurements generated by one or more monitoring sensors of one or more devices, including one or more monitoring sensor measurements from a respective monitoring sensor of a respective device and obtains one or more system signals including a respective system signal corresponding to current operation of the respective device. 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 processing apparatus, optionally integrated into a device having a plurality of sensors including a magnetometer, generates navigational state estimates for the device. The processing apparatus has a magnetometer-assisted mode of operation in which measurements from the magnetometer are used to estimate the navigational state and an alternate mode of operation in which the navigational state of the device is estimated without measurements from the magnetometer. For a respective time period, the processing apparatus operates in the alternate mode of operation. During the respective time period, the processing apparatus collects a plurality of magnetometer measurements and determines whether they meet measurement-consistency requirements. If the measurements meet the measurement-consistency requirements, the processing apparatus transitions to the magnetometer-assisted mode of operation. If the measurements do not meet the measurement-consistency requirements, the processing apparatus continues to operate in the alternate mode of operation.
