STRIDE CALCULATING DEVICE, PORTABLE TERMINAL, POSITION INFORMATION PROVIDING SYSTEM, CONTROL METHOD FOR STRIDE CALCULATING DEVICE, AND PROGRAM

摘要

The present invention achieves a stride calculating device that calculates a user's stride without having to perform complex processing. The stride calculating device comprises: a height-difference calculating unit (1313) that calculates a stride calculating device (1) height-difference at two specific points in time using the vertical-direction acceleration of the stride calculating device as detected by a triaxial acceleration sensor; and a stride calculating unit (132) that calculates the stride of the user from the height-difference and the length of the user's legs.
