rhythmism is an entertainment system which uses original maraca based devices and manipulates a video like Visual Jocky (VJ) on real-time. Focusing on both of the structure and operating characteristics of the maracas, every user can enjoy VJ performance intuitively and physically. rhythmism utilizes two different maracas; “material maraca” and “effect maraca”. After inserting material balls into the material maraca, the user can control the playing speed of the motion graphics data by shaking the maraca and can switch the current data by rotating the maraca. On the other hand, the user can control each parameter of the inserted visual effect ball by shaking the effect maraca and, switch the current effect by rotating it.
