Abstract: A game apparatus acquires operation data from an input device at least including a gyroscope, wherein the operation data at least contains angular rate data from the gyroscope. The game apparatus sets a predetermined reference position in a predetermined plane when a player inputs a predetermined instruction, and then calculates a coordinate point based on the angular rate data, wherein the coordinate point represents a position in the predetermined plane relative to the reference position. A game process is performed based on the coordinate point.

Abstract: Angular velocity data for specifying the position and the orientation of the first controller is inputted to a game apparatus.

If it has been determined that the sword object will collide with the enemy object, whether or not to perform hitting processing for the enemy object is determined based on the swing direction of the first controller.
