Abstract:
Orientation in an external reference is determined. An external-frame acceleration for a device is determined, the external-frame acceleration being in an external reference frame relative to the device. An internal-frame acceleration for the device is determined, the internal-frame acceleration being in an internal reference frame relative to the device. An orientation of the device is determined based on a comparison between a direction of the external-frame acceleration and a direction of the internal-frame acceleration.
