A new mobile phone in Japan from wireless carrier NTT DoCoMo has motion sensors. You can even use the phone to play games through movements, just like the Nintendo Wii game console.

The D904i from Japan's largest carrier, DoCoMo, comes with a motion sensor that detects shaking and tilting. For game play users "can move the handset like a tennis racket or fishing pole in easy-to-play games, similar to those on Nintendo Co's popular Wii."

And the new DoCoMo phone isn't alone:

Meanwhile, two new phones from Sharp and Matsushita Electric Industrial use their built-in cameras to detect motion. Users can control a hip-hop dancer by wagging a finger in front of the camera, for example, or throw punches in the air for a boxing match.

The new motion-equipped phones are scheduled to ship in Japan in May. No word yet when motion-equipped phones will hit the U.S.
