Yet another unnumbered and unreferenced Sony patent appears to have emerged... somewhere. These startling lack of details come via Siliconera in its tale of Sony patenting "A Motion Control System That Uses Ordinary Objects As Controllers".
The story tells of a "recently published patent from Sony" that includes a camera that "can dynamically map an object — any real world object — for use in a video game". It states that any real world object can "include items such as coffee mugs, drinking glasses, books, bottles, etc", which is a relief.
We are trying to track down the actual details of the patent so we can either say: "Sony had Natal Before Microsoft" or "Sony had Natal After Microsoft". Check back later.
