The Kinect is a powerful device, but it still has its limits. For now, it can essentially map out a skeleton of your body as long as you are standing several feet away from it. It works for some party games but still doesn’t have what it takes to control games that require split second twitch reactions. However, a new peripheral called the NUIA eyeCharm can apparently make the Kinect so sensitive that it can track the very movements of your eyes.
