Filing for creation of 'a real-time three dimensional interactive environment using a depth sensing device'

Sony is building its own Kinect-like motion sensing prototypes, newly released patent files reveal.
As reported by PlayStation lifestyle, the patent was filed in October 2011 to protect the creation of a “real-time three-dimensional interactive environment using a depth sensing device”.

It also describes that the device “includes obtaining depth values indicating distances from one or more physical objects in a physical scene to a depth sensing device.”
It is important to note however that by convention, numerous patent filings by games companies do not materialise into final products.
