Motion measurement apparatus, motion measurement method, and motion measurement program

Abstract

A motion measurement apparatus includes an inertial sensor and a host terminal. The inertial sensor measures a motion. The host terminal includes an input section and a control section. The input section is used to input an item identifier allocated to each motion of a user. The control section generates a control signal for controlling a sampling rate of the inertial sensor according to the item identifier which is input via the input section, and outputs the control signal to the inertial sensor.
