A method of calibration of a system designed for analysis of ground reaction forces of a user's feet, wherein the system comprises a left and right footwear each with a plurality of force sensors. The method includes (a) obtaining respective data measurements from each force sensor over a time period while the user's feet are in the left and right footwear; (b) determining a respective statistic of the respective data measurements for each force sensor over the time period; and (c) storing the respective statistic as a respective calibration offset for a respective force sensor. The respective statistic may comprise a minimum, a maximum, an average, a median, a percentile, and/or a statistical model of the respective data measurements.

Methods for calibrating a motion and ground reaction force analysis system

A method of calibration of the motion and force processing system designed to analyze user's feet motion in relation to the ground reaction forces wherein the system comprises multiplicity of motion and force sensors embedded in the insole of a footwear and wherein the calibration is intended to compensate for errors in fabrication and assembly of the sensors, insoles, footwear and for the user's natural pronation, in a single procedure.
