It appears that some information about the next-generation Kinect has leaked out via a Microsoft patent filing.
Kinect could be taking body recognition further in the future and transition to a body scan technology. Instead of simply detecting a present body, a body could be scanned to resemble the real life image of a player within a video game.
While we are waiting for Nintendo's new Wii controller that is scheduled to get its first public showing at the upcoming E3, it is clear that Microsoft is aggressively pursuing a user model without controllers. A much more detailed avatar could bring much greater control to Kinect games, while we also suspect that the integrated cameras will get resolution upgrades as well as a much more powerful processor.
There was no information when this technology could become available, but if we assume that the patent was filed in January of this year and if we consider the fact that Microsoft provides a very detailed description of its body scan technology, we would speculate that Microsoft will surprise us at E3 as well. Even if Nintendo will show a new Wii, Microsoft could still be grabbing headlines with a much more advanced Kinect.
