A first input acceptance unit (501) accepts a first kind of instruction input given by a player via a first controller. A second input acceptance unit (502) accepts a second kind of instruction input given by the player via a second controller that is variable in position and/or orientation. An acquisition unit (503) acquires the variation of the position and/or the variation of the orientation of the second controller. A setting unit (504) estimates from the acquired variation whether or not the player is playing a game by using the second controller or whether or not the second controller is in an available state. The setting unit (504) sets the game mode to a double judgment mode or a single judgment mode according to the result of the estimation. An advance unit (505) advances the game by the first kind of instruction input and the second kind of instruction input when the game mode is the double judgment mode, and advances the game by the first kind of instruction input when the game mode is the single judgment mode. |
