According to a patent filed in late 2011, Sony is working on a camera that would plug into a PlayStation and recognize a player’s movements and their positioning in a 3D space. The patent was filed by Richard Marks, the main development talent behind Sony’s PlayStation Move.

The new devise appears to be an evolution off of the PS2’s EyeToy, and the PS3’s PlayStation Eye and Move peripherals, along with Microsoft’s Kinect. While this is an intriguing, even likely, addition to the PS4, the patent is not an announcement or verification that such a device will ever release.
