Eurogamer reports that Microsoft fixed a major Kinect implementation issue by allowing Kinect to recognize players who are seated. The method Microsoft used to create skeletal models in the software set the base node at the bottom of the spine. When people were seated with knees in front of their pelvis, Kinect got confused. Microsoft engineers modified the base node from the bottom of the spine to the back of the neck.
Previously, developers had to specifically code for lazy (sitting) gamers but this functionality is now built into the system. Unfortunately these changes will miss most of the peripheral’s launch line-up.
