Kinect visionary talks tech

Alex Kipman - Xbox's director of incubation, and guiding mind behind the Natal project - has given a remarkable interview, going into considerable depth on some of the most crucial and controversial elements of the motion sensor. It's the interview Digital Foundry would've killed for, but luckily we were able to sneak a few questions to the team that reveal new information on how Kinect works and the ways in which its systems are integrated into the Xbox 360.

One of the biggest and most controversial stories surrounding the system has been the removal of an onboard motion processor. Instead of processed data being transferred over USB, instead the raw streams from the camera, depth sensor and mic are beamed across to the 360, where the CPU and GPU work in concert to decode and process the data. Kipman makes the claim that the console has the power to spare, saying that no 360 game - not even the latest state-of-the-art title - uses all of the CPU and GPU power available.

"In a New Scientist feature published at the beginning of this year, Kipman himself estimated that system resources consumed came to between 10 and 15 per cent. This has now been revised down into "single figures", presumably through the evolution of the system's libraries, but Kipman acknowledges that accommodating Kinect involves making compromises."

"Not all features are created equal, you can totally imagine a game that's using practically the entire of the Xbox 360 and still uses identity recognition. You can have a game that uses a small vocabulary of voice recognition that will still have pretty much 100 per cent of the processing. And on and on."

-I expect to see better things to come from Kinect.

Interesting read. I still think that the next gen Kinect will need HD camera, and if the device will still require the console CPU to do the processing, it will need a USB3 speed connection. I think the USB2 speed connection is a bottleneck for the video feed. This causes not enough video info, which causes lag and inaccuracy. Still think they needed to keep the chip on camera though.
