Move uses several different techniques for tracking motion as well as position. It's up to the developer to decide how they want to implement everything together, or which methods to use. For The Shoot, the light ball and camera are only used to keep the reticle calibrated. You can actually shoot with a fair amount of accuracy with the remote behind your back with the ball resting against it, completely hidden from the camera. It will get off center over time if you keep aiming the remote in an extreme angle off screen, but if you keep it pointed at the screen you could probably play through an entire level behind your back (I played about a half a level this way and finished with 87% accuracy with most misses due to the fact that I was aiming with both hands behind my back). Tumble actually requires the use of the ball as it depends upon motion in the Z axis to "reach into the screen". You have to move towards the screen and back to move pieces in 3D space. The game is probably the best example of how the Move ball is used to determine depth (measurements being based upon the relative diameter of the ball as the camera sees it: closer = larger diameter, farther = smaller diameter). As soon as the ball is not visible to the camera, the "laser pointer" disappears as this is how this particular game tracks player movement/aiming. In Sports Champions, one can still manipulate the game selection screen (which is aim based in 2D; no depth/Z axis) even if you are standing at an extreme angle off to the side, well outside of the lens angle range of the camera, or with the light ball or camera completely obscured. Once you play a game that requires use of the Z axis like frisbee (which uses player's forward motion to provide data on each throw), the ball must be in view of the camera. Anyone that has a legitimate interest in seeing and understanding how the Move works can do similar such experiments with the various demos available. You'll see how each game works a little differently due to the wide range of motion based options and tracking systems Move was designed with. It's a very versatile system. |
thank you for your effort, but i believe you missed my point.
i know how the move works, but i don't understand how Maxwell could state that Tumbles pointing is based on the gyroscope, when it obviously is not in the way he describes.
“It appeared that there had even been demonstrations to thank Big Brother for raising the chocolate ration to twenty grams a week. And only yesterday, he reflected, it had been announced that the ration was to be reduced to twenty grams a week. Was it possible that they could swallow that, after only twenty-four hours? Yes, they swallowed it.”
