1. A method of monitoring human activity using multiple sensors comprising:

  • monitoring accelerations using an inertial sensor;

    identifying a user activity based on the accelerations;

    making a first estimation of a user activity statistic associated with the user activity based on the accelerations, the user activity statistic being one of;

    a distance traveled or a speed of travel;

    making a second estimation of the user activity statistic based on location information obtained by a location based sensor; and

    calculating the user activity statistic based on the first estimation and the second estimation, wherein the calculated user activity statistic is a result of a weighted combination of the first estimation and the second estimation.
