Abstract:
A game apparatus obtains data from an input device including at least a gyroscope and an acceleration sensor, and calculates an orientation of the input device. The game apparatus includes orientation calculation means and correction means. The orientation calculation means calculates a first orientation of the input device in accordance with an angular rate detected by the gyroscope. The correction means corrects the first orientation so as to approach a second orientation of the input device as the angular rate decreases, the second orientation being an orientation in which a direction of an acceleration represented by acceleration data detected by the acceleration sensor is a vertically downward direction.
