The ball is for sensing position, just like in studio mo cap suits.
It also allows fairly simple calculation of depth, the software knows how big the ball is, so by comparing how big it looks to the camera to how big is should look the program gets distance information.
The gyro is the same kind of accelerometer chip used in the Wii.
While its tablet world topping pixel density, Tegra 2 silicon, and fresh to death OS certainly sound awesome, we had to get our grubby mitts on one to see if it's as good as its spec sheet would have us believe.

Was really hoping they'd get rid of that ugly ball.
Other than that, it looks good.
Trust me, if they could have gotten rid of it, they would. It's obviously a major part of the whole thing.
They need it, its for sensing the angles and which your holding it. (Its a gyroscope)

I heard that they needed it for sensing the angle (some kind of gyroscope perhaps)
=o]
Well considering the issue of angles they most probably require something to detect them (Mayhaps it is a gyroscope)
