1. A method, comprising:

  • at a computing device that includes a first processor, a second processor and a third processor,receiving, at the first processor, first sensor data from a first sensor;

    determining, at the first processor, a motion state of the computing device using the first sensor data;

    in response to determining that the motion state corresponds to a predetermined motion state, activating the second processor;

    receiving, at the second processor, second sensor data from a second sensor;

    determining, by the second processor, that the motion state corresponds to the predetermined motion state using the second sensor data;

    determining whether an accumulated time of the computing device in the motion state exceeds a predetermined threshold; and

    in response to determining that the motion state corresponds to the predetermined motion state using the second sensor data and that the accumulated time exceeds the predetermined threshold, sending the motion state to the third processor.
