We created a controller for detecting spirit of a player, and a game to operate with this controller. Based on the premise that the action is energetic when player has spirit, the controller judges spirit from the change in acceleration. The game competes for the time until all enemy is struck down. This game was made with Unity. An acceleration sensor is mounted on the controller. When a player behave with spirit, special attack is put. When we observed gameplay, the case that player was playing with spirit was seen, and special attack was put. However, after the player understood the reaction of the sensor, gameplay without spirit was also seen.
