Nintendo Gaming / RE: So how does the controller work, anyway?

Yeah my guess is the Revolution can measure the signal response times from the controller to the sensors on the sensor bar to calculate your location in 3d space. It can also measure the tilt/rotation of the controller.
So it always knows where you are in 3d space and it knows in which direction you are pointed. Combine this with some type of calibration in order to account for various TV sizes and the various relative placements of the sensor bar to the tv screen and it can calculate where are you pointing to on the screen.
The calibration would really only be a one time setup as long as you don't move your TV or the sensor bar. IT would probably involve pointing at the center and four corners of the screen like calibrating a joystick on the pc and pressing a button each time. And maybe repeating it a few times until it feels right.
edit: perhaps they'll make it a requirement to center the sensor bar over or under your TV. I can see this helping calibration.
