Patent ID: 8416186

Claim:
An input apparatus comprising: a first acceleration sensor to detect a first acceleration in a direction along a first axis; a second acceleration sensor to detect a second acceleration in a direction along a second axis different from the direction along the first axis; a first angular velocity sensor to detect a first angular velocity about the second axis; a second angular velocity sensor to detect a second angular velocity about the first axis; an angle calculation means for calculating, based on the first acceleration and the second acceleration, an angle about a third axis that has a predetermined angle with respect to an acceleration detection surface including the first axis and the second axis, the angle being formed between a combined acceleration vector of the first acceleration and the second acceleration and the second axis; and an information output means for correcting the first angular velocity and the second angular velocity by rotational coordinate conversion corresponding to the calculated angle, and outputting information on a first correction angular velocity and a second correction angular velocity obtained by the correction.
