Abstract: An inertial measurement unit is affixed to a rigid body. The inertial measurement includes a gyroscope that measures a first angular velocity and an angular acceleration; a first accelerometer that measures a first acceleration; a communications unit that receives a measurement signal, the measurement signal including a second acceleration transmitted from a second accelerometer, the second accelerometer being affixed to the rigid body; and a controller that calculates a relative orientation of the inertial measurement unit and the second accelerometer, and a distance separating the inertial measurement unit and the second accelerometer.

Abstract: An information processing apparatus includes circuitry configured to acquire information corresponding to a reference orientation that indicates a spatial position of a sensor unit attached to a golf club. The reference orientation is determined based on a vector projecting in a normal direction from a planar surface of the golf club. The circuitry acquires a measurement signal generated by the sensor unit in response to a movement of the golf club, the measurement signal including measurements of one or more of an angular acceleration, a linear acceleration, and an angular velocity. The circuitry generates data corresponding to a motion path of the golf club based on the measurement signal and the reference orientation. The circuitry controls an interface to output the generated data corresponding to the motion path.
