A game apparatus obtains data from an input device including at least a gyroscope, and calculates a two-dimensional coordinate point corresponding to the data. The game apparatus includes orientation calculation means and coordinate calculation means. The orientation calculation means calculates an orientation of the input device in accordance with an angular rate detected by the gyroscope. The coordinate calculation means calculates the two-dimensional coordinate point, wherein the two-dimensional coordinate point represents coordinates of an intersection R between a line segment continuing from a vector VZ representing the orientation of the input device within a predetermined space and a predetermined plane within the predetermined space.
