Japanese phones

In Tokyo they just recently found a new way to make your phone motion censored. They will function just like a Wii controller. They can tilt the controller just like a steering wheel. Some other phones in Japan have introduced camera sensors. lets say if you are playing a boxing game, you throw a punch in front of the camera, and it will do it in the game. The only thing that isn't good about this new technology is that it is hard to stay focused on the screen with all that movement. All i know is that America needs to get with it!
