Abstract: A game apparatus includes a CPU, and the CPU sets a moving direction, that is, a position and an orientation of a moving object within a game space on the basis of angular velocity data transmitted from a first controller, that is, an attitude of a gyro sensor unit (gyro sensor). Then, when a second controller is drawn toward a near side in a state that a C button and a Z button thereof are simultaneously pressed, and the C button and the Z button are simultaneously released in that state, the moving object is shot.

Abstract: A game apparatus includes a CPU, and the CPU controls a moving object within a virtual space on the basis of acceleration data and angular velocity data which are transmitted from a controller. For example, before the angular velocity data is above a predetermined magnitude, a position and an orientation of the moving object is controlled on the basis of the angular velocity data. When the angular velocity data is above the predetermined magnitude, an initial velocity of the moving object is decided on the basis of the acceleration data, and a moving direction (orientation) of the moving object is decided on the basis of the angular velocity data. Thereafter, the moving object moves within the virtual space according to a general physical behavior.
