umm the closest thing to the kinect is the Eyetoy which was released 7 years ago by SONY
this is an far more advanced motion sensing device made up by SONY's R&D team and what ever they create that is new they patent it since SONY, JVC, TEC, SAMSUNG in Japan are always racing themselves for the newest technology and they dont always want to share.
this is one of the possible millions of patents SONY has under there belts
Of Course That's Just My Opinion, I Could Be Wrong
