A game apparatus detects an input position, on an input plane, at which an input operation has been performed. The game apparatus also detects an operation sound that occurs due to the input operation performed on the input plane. The game apparatus evaluates the detected operation sound, and obtains a result of the evaluation (e.g., volume of the operation sound). The game apparatus performs game processing by using the detected input position and the result of the evaluation. This enables the game apparatus to perform more complex processing by using a touch operation as input information, and allows a player to provide more complex instructions based on the touch operation.
