Abstract:
A method of estimating a stride length includes: detecting acceleration of a user's vertical movement; and estimating a stride length using the detected acceleration by changing the degree of correlation between the acceleration and the stride length, in which the stride length is increased as the detected acceleration increases, based on user's speed.
