Methods and apparatuses for use in determining a motion state of a mobile device

摘要

Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile device to classify and/or otherwise determine a “motion state” of the mobile device. The mobile device may, for example, classify a motion state of the mobile device based on sensed data (e.g., from inertial sensors, environmental sensors, etc.) that may be filtered based on a vibration profile. A motion state may then affect operation of one or more other functions performed or supported by the mobile device.

1. A method for use in classifying a motion state of a mobile device, the method comprising: at a mobile device:
filtering sensed data from one or more sensors at said mobile device based, at least in part, on a vibration profile for at least one mechanism capable of inducing movement of at least said mobile device; determining a variance value corresponding to a change over a period of time for at least a portion of said filtered sensed data; and classifying a motion state of said mobile device based, at least in part, on a comparison of said variance value with at least one threshold value.
