<p>An input apparatus includes a first acceleration sensor, a second acceleration sensor, a first angular velocity sensor, a second angular velocity sensor, and velocity information output means. The first acceleration sensor detects a first acceleration value in a first direction. The second acceleration sensor detects a second acceleration value in a second direction different from the first direction. The first angular velocity sensor detects a first angular velocity value about a first axis in the first direction. The second angular velocity sensor detects a second angular velocity value about a second axis in the second direction. The velocity information output means calculates, based on the first and second acceleration values and the first and second angular velocity values, a first velocity value in the first direction and a second velocity value in the second direction, and outputs information on the first velocity value and the second velocity value.
