The purpose of this research is to estimate the angular velocity and direction of the rotational axis of the flying disc by a tri-axial accelerometer. A subject performed throwing by using the flying disc attached the accelerometer. And, the closed up release point image was acquired using the high speed cameras. The angular velocity was estimated from the translational acceleration. The direction of the rotational axis was estimated from the component of the centrifugal acceleration. Each estimated value was compared to the value calculated by the high speed cameras. The angular velocity estimated by both the accelerometer and the high speed cameras were similar. And it was observed that the rotational axis on the sensor coordinate system changed during flight phase.
