The important part of all this isn't really the robotic arms but more the controller device. A cylindrical interface is gripped by each hand and measures each contact point on your palms and fingers, which allows for the slightness variation in applied pressure to control the attached robo-arms. The cylindrical interface is also mounted upon a movable controller which will register directional movements. So what this means is all your finger, hand and arm movements are transferred over to the robo-arms without even getting out of your seat.

But yeah, there's still no super-powerful robot arms... sorry [MeisterGRIP at SIGGRAPH]

The game in the video above requires each player to try to hit a projected target on the court with the Bouncing Star. As a player picks up the ball and begins to throw it on the court, the accelerometer in the ball acknowledges motion and transforms the ball's color. Using infrared, the ball can interact with the digital court; when the ball touches down or races by, the court can display a motion graphic or some other cool visual reaction.

Because of the low light in the video above, the intensity of the ball's interaction with the display was not well documented, but the idea of a ball wirelessly interacting with a digital court is pure genius. If the same principles of this Bouncing Star could be integrated into all sports using balls, we would have some amazing games to play and to watch. In Tron, the crazy Frisbee game was just a program inside of a computer, but this Tron-like tech—designed by engineers at Japan's University of Electro-Communications—could soon happen in real life. You hearing this, Nintendo? [Bouncing Star at SIGGRAPH]
