Outline of Final Research Achievements

The purpose of this study was to develop a motion capture system with MEMS inertia sensors which we can use under the environment affected by centrifugal force such as alpine skiing. Many previous studies have developed it with gyroscope, accelerometer and magnetometer. However, those systems have the problem that the measured data is disturbed by centrifugal force and/or magnetic field distortion. In order to prevent it, we developed the measurement method in which accelerometer and magnetometer are not used, in other words, only gyroscopes is used. The accuracy of this method was similar to those of other studies.
