We created a controller and a game for detecting spirit of a player.
Based on the premise that the action is energetic when the player has spirit, the controller judges spirit from the change in the value of the acceleration sensor.
In this game, the player is able to use two types of special attack corresponding to the action of player.
One of the action is forward movement of the controller and the other is swinging the controller horizontally.
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.
We used the force of grasping was detected by a pressure sensor installed in the grip.
In the case of the swing action, using a pressure sensor may not be effective.
