Abstract: Operation information which is output, depending on a motion of an input device is successively obtained, and based on the operation information, a direction and movement velocity of the input device is determined. Next, it is determined whether or not the movement velocity is larger than or equal to a first threshold value. When the movement velocity is larger than or equal to the first threshold value, a path along which an object is moved in a virtual world is determined based on predetermined information about the movement path. When the movement velocity is smaller than the first threshold value, a path in which the object is moved in the virtual world is determined based on the determined movement velocity. Based on the determined movement path, it is displayed how the object is moved through positions in the virtual world.

Abstract: An image is placed, based on a predetermined designation input, on a predetermined placement position in relation to a display area, and displayed. The image is enlarged and reduced in accordance with an enlargement ratio of the image, and an area within which the placement position can be set is changed in relation to the display area in accordance with the enlargement ratio. Then, based on an obtained designation input, a position within the area, which position corresponds to the designation input, is calculated as a placement position, and the image having been enlarged and reduced is placed on the placement position. The image is then displayed on a display device.

Abstract: First, operation data including at least acceleration data and angular velocity data is obtained from an input device including at least an acceleration sensor and a gyrosensor. Next, based on the acceleration data and the angular velocity data, a moving velocity of the input device itself and/or a relative positional relationship between the input device and a center of a rotation motion applied on the input device itself is estimated. Then, predetermined game processing is executed based on the estimated moving velocity and/or relative positional relationship.

Abstract: As an example, a value obtained by adding the magnitudes of a plurality of angular velocities around respective axes indicated by angular velocity data obtained from an input device including gyroscopic sensors, is used to calculate a rotation parameter indicating a rotation amount. A predetermined object which is rotated, depending on the rotation amount corresponding to the rotation parameter, is displayed on a display device. As another example, when it is determined, based on the angular velocity data, that the attitude of the input device is stable, a stability flag which indicates that the attitude of the input device has been at least once stable is set and updated to ON. When there is an input device whose stability flag is OFF, the aforementioned determination is performed and a screen including a result of the determination is displayed on a display device.

Abstract: While a ball is rising, a point of attention of a virtual camera is set at the current position of the ball. At the instant when the movement of the ball is changed from rising to falling, the point of attention of the virtual camera is moved from the position of the ball to the position of the shadow of the ball. While the ball is falling, the point of attention of the virtual camera is set at the position of the shadow of the ball. Thus, in a baseball game or the like, a game image capable of providing a realistic feeling to the player and also allowing the player to grasp an area below the ball before the ball drops on the ground can be generated.
