To pick up on sk8er's remarks, some info from our friend wikipedia: On May 8, 2006, during their press conference, Sony announced that their PlayStation 3 game console would feature motion sensing functionality. However, the technologies work somewhat differently, as the PlayStation 3 controller does not utilize a positional sensor. Sony's announcement was made nearly eight months after Nintendo unveiled their controller. This was perceived by many observers as a copycat maneuver. It should be noted, however, that concepts and implementations of motion-sensing game controllers date back to before Nintendo's announced agreement with gyro sensor developer Gyration in 2001, or even Sony's EyeToy concept, which dates back to 2000. Around 1999, several gamepads featured tilt-sensing technology. One such device (though not the first) is the Microsoft Sidewinder Freestyle Pro, which was announced back in 1998.
