>> Number 4. We've got another cool piece of hardware. Remember when we added the accelerometer and how that opened up a whole new vista of gaining? Because we're adding a gyroscope.[applause] We're adding a three access gyro which is fantastic pitch rolling yaw also rotation around gravity and we've tied the gyro and the accelerometer and even the compass together to provide six access motion sensing and we've got some new core-motion APIs that you can call that give you extremely precise position information. It's perfect for gaming and one of the reasons it's perfect is because it's built into every Iphone 4 so you know it's there. so this is the a little act that we wrote and this is being run with the accelerometer now and as you see with the accelerometer I can tilt it from side to side or backwards and forwards but I can't, it doesn't move when I rotate around gravity and the positioning is good but not super precise. So now by tapping the word accelerometer it's going to change to the gyro and now I get much more precise movement here and as you see it rotates around gravity so I'm going to play this game here and I think I'll take this one off, all right. And maybe I'll take this one out and we'll take that one out. ^M00:01:50 [ Laughter and applause ] ^M00:02:06I practiced this a little bit. ^M00:02:08 [ Laughter and applause ] ^M00:02:18 Well, you get the idea.
