Microsoft's research team has published a paper to improve the speed and accuracy of their Kinect. The team stripped away Kinect's existing technology and replaces it with a new way of "thinking". Instead of using recognition systems built to track limbs, the researchers built one that could identify body parts in an image.
This would not only remove the need for Kinect to repeatedly calibrate, but would also make its detections speed a lot faster.
Its good news for gamers, but the bad news is that there still isn't many games out there for Kinect just yet. Come on! We've been waiting for awhile already now!
