The new 1080p cameras are a wide field of view, which we saw in greater detail during the Skype demo with four chat partners, and looks great, but no one's too concerned about that.

The truly impressive stuff, though, comes from the brains of the Kinect. Its improved skeleton mapping is crazy accurate, and can track your individual hand motions and shoulder shrugs. The muscle tracker is also borderline ridiculous. It can tell what parts of your body have pressure on them. It knows where you're putting your weight as you lean side to side, and how much power goes into each motion, by tracking speed. It knows if you lob a slow fake punch, and it knows if you slice a fast uppercut through the air, and shows you with popping white circles around your fists or feet or head. Orientation tracking is cool as well, and will apply more to how your character moves around in games.

The heart rate monitor, which reads your heart rate just by freaking LOOKING AT YOU, seems pretty accurate, but we obviously weren't able to test against an actual heart monitor. Still, do you see this, guys, seriously this is a thing that will be in living rooms. It's very cool.

The face recognition recognizes you, personally, and can tell if you're "engaged" or not engaged, meaning if you say "Xbox pause" while not looking at the TV, it won't listen to you. This seems like something you'd maybe want to turn off, but it's still impressive it can read your expression and know if you're happy, sad, or bored.

Kinect 2 doesn't just see you, though; it can hear you too. In fact, it can hear your voice, specifically, through whatever ambient game and/or movie noise that's going on around you. Want to give a command in the middle of a particularly loud concert video or melee? You don't have to shout for Kinect 2 to listen and comply.
