慣性センサと足底圧センサを用いた簡便なスキーターン計測

抄録

We propose a convenient and easy way for skiers to learn how to execute turns by themselves. It is important for skiers to recognize their own turns while actually skiing. A compact measurement method is effective for this purpose. We used the two inertial sensors and one set of the plantar-pressure sensors. The acceleration components of the inertial sensors were used to log the motion of skis. The plantar-pressure sensors were used to measure plantar-pressure distribution. We analyzed how the feet transmit force to skis with the plantar-pressure distribution. One intermediate skier and one expert skier participated in this experiment. They skied in short turns in six trials totally. According to the results of the experiment, the data of both sensors for intermediate skier's and expert skier's turns were clearly different. Therefore, our proposed measurement method will enable skiers to conveniently recognize their ski-turns on their own.
