System and method for improving orientation data
First Claim
1. A method for filtering data associated with a first sensor coupled to a computing device, the method comprising:
- receiving a signal from the first sensor;
detecting a change in a variability of a first signal parameter from a plurality of signal parameters from the signal; and
adjusting, based at least in part on the detected change in the variability of the first signal parameter, a filter parameter of a filter used to filter a second signal parameter from the signal, wherein the filter parameter for the filter comprises a gain for the filter, and wherein adjusting the filter parameter of the filter comprises changing the gain for the filter inversely proportionally to the variability of the first signal parameter;
filtering the second signal parameter of a second sensor signal using the filter having the adjusted filter parameter;
determining, using a second sensor, that the computing device has transitioned to a stationary state; and
transitioning the first sensor to a low power state.

Abstract
Aspects of the disclosure relate to computing technologies. In particular, aspects of the disclosure relate to mobile computing device technologies, such as systems, methods, apparatuses, and computer-readable media for improving orientation data. In one embodiment, techniques are described for filtering data associated with a sensor coupled to a computing device, by receiving a signal from the sensor, detecting a change in a variability of a first signal parameter from a plurality of signal parameters from the signal, and adjusting, based at least in part on the detected change in the variability of the first signal parameter, at least one filter parameter of a filter used to filter a second signal parameter from the signal.
