Pretty sure it can track your arms/hands as well as your head.
Initially Kinect was having issues tracking players while sitting because it was using the pelvic area as the "base" of the skeletal tracking system, and this area would be indistinguishable by the device while seated. They have since moved that spot to the upper chest/neck area, so that Kinect can continue tracking a player's upper body in such situations.
