Abstract
An information processing device includes an acquisition unit which acquires information of acceleration, angular velocity, and magnetic intensity of an operation device, a coordinate conversion unit which converts the angular velocity acquired by the acquisition unit into global angular velocity in a global coordinate system using information of posture angles of the operation device, an initial posture angle calculation unit which calculates a posture angle of the operation device in the initial stage in the global coordinate system based on the information of the acceleration and the magnetic intensity, an updating unit which updates the posture angle of the operation device in the global coordinate system based on information of the global angular velocity, and a control unit which causes the coordinate conversion unit to convert the first angular velocity into the global angular velocity and to convert a second angular velocity into the global angular velocity.
