Sony has never made as big a splash with its motion sensing technology (Sixaxis and DualShock 3 controllers) as has Nintendo with the Wiimote and Nunchuck. That’s not to say that Sony’s given up on the concept — far from it as recent patent applications show.

The new device, as envisionedrent a car bulgaria in the patent application, combines three different mechanisms for tracking motion:
* Accelerometers in the controller itself
* Video tracking (via the Playstation Eye cam), potentially offering face or gesture tracking
* Ultrasonic tracking to further provide an absolute tracking mechanism (using an array of microphones)

The new system is modular, meaning that the controller itself can “break apart” and be reconfigured in different formats for different games.

Of course this is still at the patent application stage now, but its obvious that Sony’s still firmly in the motion control camp.
