Abstract:
1. An input device comprising: a main body; a motion sensor unit configured and arranged to generate a physical quantity signal corresponding to movement of the main body in a first two-dimensional orthogonal coordinate system defined by a mutually orthogonal Y-axis and Z-axis in a first plane perpendicular to an X-axis that coincides with a pointing direction of the main body, the motion sensor unit including a coordinate conversion processing unit configured to perform coordinate conversion processing based on the Y-axis acceleration detected by the Y-axis acceleration sensor and the Z-axis acceleration detected by the Z-axis acceleration sensor, the coordinate conversion processing unit being configured to convert the Y-axis angular velocity detected by the Y-axis angular velocity sensor and the Z-axis angular velocity detected by the Z-axis angular velocity sensor to a U-axis angular velocity and a V-axis angular velocity, respectively, in a second two-dimensional orthogonal coordinate system defined by a U-axis corresponding to a horizontal axis in the first plane and a V-axis perpendicular to the U-axis in the first plane.
