    摘要: A method for monitoring human activity using an inertial sensor includes obtaining acceleration measurement data from an inertial sensor disposed in eyewear. The acceleration measurement data is processed to determine a user activity statistic. The user activity statistic includes at least one of a current user activity, periodic human motion count, total distance traveled, vertical distance traveled, current speed and average speed.

    摘要: A personal electronic device determines its orientation by performing a number of operations. The personal electronic device determines one or more sample periods and creates rolling averages of accelerations for a plurality of axes over the one or more sample periods. The personal electronic device then identifies current values for the rolling averages of accelerations along each of the plurality of axes, wherein the current values indicate a gravitational influence and assigns a dominant axis based upon the current values.
