The New Kinect Is So Sensitive It Can Read Your Heartbeat

Microsoft claims that the new Kinect is so sensitive that it can see the slightest movement of your wrists and fingers, the tension of your muscles and, amazingly enough, even your heartbeat.

So next time you exercise in front of the TV, it will be able to tell how much you are really working out. But I bet there will be a lot more to this feature, like a first-person shooter reading your heart beat and muscle tension to spook you at the right moment. And kill you for real.
