Abstract:
1. A storage medium having stored thereon an acceleration data processing program to be executed by a computer of a game apparatus to perform a game process by using acceleration data output by an acceleration sensor capable of detecting, in at least one axial direction thereof, an acceleration applied to a game input device, the computer being caused to function as: data acquisition programmed logic circuitry for acquiring the acceleration data at predetermined time intervals; change amount calculation programmed logic circuitry for calculating a change amount value representing a change amount of the acceleration for each said axial direction with respect to time by using the acceleration data having been acquired by the data acquisition programmed logic circuitry; accumulation value calculation programmed logic circuitry for calculating an accumulation value by sequentially and cumulatively adding the change amount value having been calculated by the change amount calculation programmed logic circuitry; and direction determination programmed logic circuitry for determining, as a waving direction representing a moving direction of the game input device, a direction of the accumulation value, when the accumulation value having been calculated by the accumulation value calculation programmed logic circuitry satisfies a predetermined condition.
