Abstract: An algorithm analyzes the motion of an object to determine if a switch needs to be activated or deactivated. Accelerometers measure forces exerted upon an object to determine orientation in pitch, roll, and yaw axes, and to determine motion of the object. When threshold conditions for these orientations and movements are measured, the method combines taking moving averages of pitch, roll, and yaw, and additionally accumulating an integral of yaw to determine if an activation or deactivation condition is met. Should an integral condition not be constantly met while the moving average conditions are being determined, the yaw integral counter resets and the whole process must begin again. This method balances most unintentional activation conditions with activation latency. Another methodology tracks the motion of a wrist flick, similar to casting a fishing line, using acceleration and deceleration parameters.
