number four we've got another really cool piece of hardware remember when we added the accelerometer and how that opened up a whole new Vista of gaming because we're adding a gyroscope we're adding a 3-axis gyro which is fantastic pitch roll and yaw also rotation around gravity and we've tied the gyro and the accelerometer and even the compass together to provide six Ashe six x axis motion sensing and we've got some new core motion api's that you can call that give you extremely precise position information and 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 little app 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 and but I can't it doesn't move when I rotate around gravity and the positioning is is good but not super precise so now by tapping the word accelerometer it's going to change 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 I practice this a little bit well you get the idea
