Abstract
A method of calculating a step length of a user, which comprises the steps: input a leg length of the user; obtain a vertical acceleration when the user is walking, wherein the vertical acceleration is sensed by an accelerometer and then removed the effect of gravity; do double integral on the vertical acceleration to obtain a vertical displacement for one step of the user; calculate a step length according to the vertical displacement and the leg length by applying Pythagorean theorem.
