Microsoft Research in Cambridge wrote a paper that details a new algorithm to significantly reduce the input lag that exists in current Xbox Kinect software. The algorithm uses information collected from 3D depth maps, training the software to quickly determine a user’s activity. The image data is based on millions of samples, with people of all shapes and sizes, to ensure the software works for everyone.
The benefits of this new approach are staggering. The algorithm is capable of handling multiple players and would eliminate the need for a calibration phase. The biggest advancement, though, is the reduction of input lag. Research suggests that the Xbox could process an image at just under five milliseconds, about 45 milliseconds faster than the software currently performs.
This is yet another improvement on top of the software already being introduced in the next round of Kinect titles. Upcoming games like Child of Eden and The Gunstringer have shown improved response times in previews. The latest research shows that the software can be faster and more convenient and still run on current Xbox 360s.
I’m one of Kinect’s ten million early adopters, and while mine has been collecting dust, I’m excited about the news. Lag is the one thing keeping Kinect from being as intuitive as it should be, but the fact that it can be so easily eliminated gives me hope that the next run of games will be amazing experiences.
