Abstract
One or more rolling averages of accelerations over a sample period are created. The one or more rolling averages of accelerations are measured by an accelerometer over the sample period. A gravitational influence is identified based upon the one or more rolling averages of accelerations. A dominant axis is assigned based upon the gravitational influence.
