A game controller is placed in an operation tool 2, and the player hits the operation tool 2 as if to play a virtual drum. A body portion 4 of the operation tool 2 is formed of styrene foam. The game controller is fitted into a fitting section 18. An impact due to the hitting operation is buffered, and is detected as a change in acceleration by an acceleration sensor provided in the game controller. A game device determines the type of operation input based on an axial direction for which an acceleration differential value (quick change) equal to or larger than a reference value has been detected and the position of the game controller. |
