Have you tried using it in the menus?  Hold the controller perfectly straight but move it left to right, nothing will happen on screen till you tilt the controller.  For the game itself you center it pick up blocks which it uses the light ball to help triangulate position but the laser your on screen controller shoots out is all gyro based, and it still takes that unneeded twist to point at the edges. 

It doesn't do this for games like Sports Champions so its not the controller, its the game itself, and both me and my friend had the same experience both at his house and mine.

Tumble seems a lot more dependent upon the ball for tracking movement and controller orientation, which is not to say that it isn't supplemented by the gyro (Tumble appears to use the gyro for angular movement). My guess is the sphere tracking is the primary method being used for that particular game.

You can tell because you have to move the controller considerably more than with games that simply require the player to point and aim, which can be done from a single fixed point (like the Shoot). Games that are entirely gyro dependent should be playable from a fixed position without having to move the controller (and ball) left/right, up/down, forward/back.

It also shows some of the limitations of ball tracking too. A larger room helps as it goes "out of range" if the ball is too close to the camera (signified by the controller falling to the floor). If you move the controller outside of the camera angle, the same thing happens. It's similar to the problem the Wii has with tracking in 2D using its IR based system, which is pretty limited in angle.

Virtually all menus are 2D based. They only need track in the X,Y axis so the ball isn't even needed. So yes, these can be done 100% using the gyro.

Based on what I can tell, I believe you're also right about the "aiming laser" which can be aimed from a single fixed point by simply changing the angle at which the controller is pointing (with the ball as the pivot point, remaining at a fixed position and therefore incapable of providing any "movement" data). 

From my experience, Tumble is one of the wonkiest games for Move, but it is also one of the only games to make such extensive use of ball tracking, particularly for Z axis movement.

I think part of the confusion seems to be that a lot of people instinctively think the ball is doing the aiming as if it were firing a beam of light at the screen/camera when the aiming is typically done entirely with the gyro.

i just tried that, and it works fine for me. i just would never even got the idea to navigate like that, i find that extremely awkward.

the thing is i understand now what you mean. but i still don't understand your criticism.

That is what the game is all about, the virtual controller mimicking every move on the screen. not only does it showcase the moves potential it also feels completely natural to me. i don't see how else they should have done it.

I changed that with the comments after OkeyD, cause Tumble was my first Move game and the first game I tried all the details of the pointer, at first I thought that was how it was for all games but I tried it with Sports Champions after Okeys comments and changed my opinion to be reserved since it's all software based (at first I thought that's simply how the pointer worked), the lack of a standard bothers me but Sports Champions is fine so hopefully KZ3 turns out fine as well, which I was REALLY irritated about the pointer for FPS games was my whole reason for buying Move and Tumble made me believe it might be a waste.

you should visit the iWaggle blog on youtube in future it has all kind of information on how move works, this will help you to get a better idea of what is going on, to me it actually sounds like you are slightly confused, as tumble definately tracks the sphere when you are in game, menus are not important, but however menu interactivity works just fine with move, also play on eyepet as well it actually illuminates exactly where your sphere is and all objects line up perfectly with the way you have the move, if you cover up the sphere it does not know where to place the object as well so it will be out of position.

No I'm not lol it tracks the ball to triangulate the position of the controller in a 3D space (see greenmedics post) not control the pointer it works in conjunction within the game cause it uses the ball to know where the controller is and the gyro to know which direction to point... IE the POINTER I dislike the gyro being used as a pointer and I'm not confused at all as to how that works, the menu simply uses the gyro, while Sports Champions' menu does not nor does it in game when you need to use a pointer... I know perfectly well what I'm talking about thanks

Well that's much better I will let you off Sports champions menu's are far superior you are right, but since you can still navigate easily in tumble using the method they adopted it's a non-issue

Any concerns about using Move as an aiming device should be answered by playing The Shoot (play the demo. the game really isn't worth $40) and the upcoming Time Crisis.

Even for an adequate title like The Shoot, I didn't have any issues with "lag" or calibration and light gun games are actually an old favorite genre of mine; I've played a lot of them over the years.

The last version of the Gun Con (3) used the same IR based aiming as the Wii, complete with IR LEDs that were positioned on the TV. If the Move based version is the same, I don't see what the complaints could be. I'll wait until Time Crisis fans chip in their 2 cents, but if there are no complaints about the aiming being "laggy" or prone to losing calibration, then I'd have to call concerns completely unwarranted over the hardware.

Any potential issues would lie completely with how developers coded their aiming system.

apparantly from previews time crisis is really good with next to no lag lol, but it's like you say we shall all have to see for ourselves
