Transformable Game Controller and Its Application to Action Game

Dedicated controllers can provide rich gaming experience. However, a player must prepare many controllers to enjoy modern games that have many game items. Depending on circumstances, the shape of the controller and the shape of the game item are mismatched. This may reduce the player's sense of unity with the game character. In this paper, we propose a transformable game controller. This controller can be multiple dedicated controllers by changing its three-dimensional shape. The game system can also change the shape of the controller immediately when the shape of the corresponding item changes. The continuous shape synchronization between real controller and virtual item can provide the player rich sense of unity with the game character.
