Abstract: An example game system includes a game device, a controller device, and a portable display device. The game device calculates an attitude of the controller device, and controls an attitude of a club in a virtual game space based on the attitude of the controller device. An image of the game space including the club is displayed on a predetermined display device separate from the portable display device. An image representing a ball placed in the game space is displayed on the portable display device. Moreover, an image representing a tip of the club is displayed on the portable display device, together with the image representing the ball, when a predetermined axis of the controller device extends toward the portable display device.

Abstract: An example input processing system includes a controller device and an information processing device. The controller device transmits data representing an input position on a predetermined input surface and a detection result of an inertia sensor unit to the information processing device. The information processing device calculates an attitude of the controller device based on the detection result of the inertia sensor unit, and sets a predetermined surface in a virtual space so that an attitude of the predetermined surface changes in accordance with the attitude of the controller device. A first image representing an area in the virtual space including a position of the surface is displayed on a predetermined display device. The information processing device calculates, as a position in the virtual space, a position on the surface determined by the input position.

Abstract: An example game system includes a game device, a controller, and a terminal device which is a portable display device. The terminal device displays an image representing a ball placed in a virtual game space. The game device calculates the attitude of the controller to move a club in the game space based on the attitude, and moves the ball in response to the club striking the ball. An image of the game space including at least the ball after being moved is displayed on a display device separate from the portable display device.
