Abstract
An input device, that is worn on a portion of a user's body, includes: a sensor unit configured to obtain angular velocities and an acceleration in a first coordinate system fixed in the input device; a reference posture specification unit configured to generate a second coordinate system for a reference posture of the user; a rotation matrix calculator configured to calculate a rotation matrix that transforms the angular velocities in the first coordinate system into angular velocities in the second coordinate system using the acceleration in the first coordinate system; a characteristic value calculator configured to calculate characteristic values in the second coordinate system using the angular velocities in the second coordinate system; a command specification unit configured to specify a command according to the characteristic values; and a transmitter configured to transmit the command to the controller.
