Patent ID: 8330716

Claim:
An input device comprising: a main body having a longitudinal axis; a motion sensor unit configured and arranged to detect rotation of the main body about the longitudinal axis, the motion sensor unit having an X-axis angular velocity sensor configured and arranged to detect an angular velocity of the main body about an X-axis in a three-dimensional orthogonal coordinate system defined by the X-axis, a Y-axis and a Z-axis, the X-axis coinciding with the longitudinal axis of the main body and the Y-axis and the Z-axis being orthogonal to each other in a first plane perpendicular to the X-axis, a Y-axis angular velocity sensor configured and arranged to detect an angular velocity of the main body about the Y-axis, and a Z-axis angular velocity sensor configured and arranged to detect an angular velocity of the main body about the Z-axis; a first signal processing unit configured to execute first signal processing based on an X-axis angular velocity signal received from the X-axis angular velocity sensor; and a second signal processing unit configured to execute second signal processing based on a Y-axis angular velocity signal received from the Y-axis angular velocity sensor and a Z-axis angular velocity signal received from the Z-axis angular velocity sensor, the second signal processing being executed independently of the first signal processing.
