Abstract
A game apparatus calculates an orientation of an input device including an acceleration sensor and a gyroscope based on at least acceleration data and angular rate data acquired from the input device. The game apparatus includes a reflection rate setting unit, a first orientation calculation unit, and a second orientation calculation unit. The reflection rate setting unit sets a reflection rate representing a degree by which an acceleration indicated by the acceleration data is reflected in the orientation. The first orientation calculation unit calculates the orientation of the input device based on the acceleration when the reflection rate is equal to or greater than a predetermined first threshold. The second orientation calculation unit calculates the orientation of the input device based on the angular rate when the reflection rate is less than a predetermined second threshold equal to or less than the first threshold.
