Sony patents 'Wii-like' controller

SONY MIGHT have mocked the Nintendo Wii motion sensing controller but it seems to have patented a camera that works in a similar way.

According to the Japanese website Tech-On, a new patent filed by Sony could be used for a Wii-like control interface on the PS3.

The device allows a game system to view a pen-like controller on a two dimensional camera image, and map its position in 3D space. In other words it is remarkably like Wii's motion-sensing controller.

The patent uses Sony's PS3 Cell processor, which is apparently "optimised for image recognition." The technology is not new, but it is the first time that it has not require several cameras to operate.
