Abstract
An input device includes a main body, a motion sensor unit and a coordinate conversion processing unit. The coordinate conversion processing unit configured to perform coordinate conversion processing based on a Y-axis acceleration and a Z-axis acceleration detected by the motion sensor unit with a first two-dimensional orthogonal coordinate system being defined by a mutually orthogonal Y-axis and Z-axis in a first plane perpendicular to an X-axis coinciding with a pointing direction of the main body. The coordinate conversion processing unit is configured to convert the Y-axis angular velocity and the Z-axis angular velocity detected by the motion sensor unit 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.
