Then why does it need that bright ball at the end of the wands?  In fact,why does it even need the Eye?  If it works even when it can't be seen then it shouldn't need a camera to function at all.

well, it still has buttons on it so it should work just fine when it can't see the ball, it just won't be motion sensitive.

fail kotaku, fail.

and yes, the Move controller can still be tracked by the console because of the accelerometers and all the stuff the controller has inside besides the glowing ball.

that's how the Wii works, the Wii has a infrared sensor that tracks more precisely the movements....

shit, double post, i'm sorry! =/

Why does the Wiimote need the IR bar? Also the ball is there to help the Eye as it changes colors based on your surroundings.

Also when I say that it still works I don't mean fully. It is limited once the Eye is gone, but it can still be used with no issues to navigate through your XMB, play Blurays (Rewind, Fast Forward, etc...). I think you can't point and click.

The Magnetometer is what helps it function without the Eye if I am not mistaken. This is why the Move still works when it is behind your back.

I am trying to find the article on N4G that shows how it works without the PSEye.

Thanks for that video. 

That was actually much more informative than these "professional" sites we hear from all the time. I am surprised it worked with that big ass light behind it, not to mention the PSEye changed it's light sensitivity like that to work in brightly lit rooms.

Very very impressive.

I can't wait for Kinect stress tests. MS said it can work in all lighting conditions, so we should see something similar. Should be a good video. Hopefully iWaggle does one too.

It is an issue with games though.  From the Joystiq review:

"I did run into a couple of issues, however. The first being the fact that I have a coffee table in front of my couch. This is a problem (as is anything on top of a coffee table) in that, should you wish to play a game that tracks the Move's colorful orb while sitting, a table will prevent the PS Eye from seeing the orb – which is a problem in games like Tumble that have you placing the controller near the floor at times. Something as small as a sake set on my table was enough to create a "blind spot," actually."

Standing up should help, right? Well, it did – although pretty much all of the games' calibration screens (you usually have to point the Move controller at the PS Eye like a flashlight and hold the T or Move button) displayed an "ideal position" box for me to stand in, which had me moving roughly eight feet back from my TV. Basically, this is right to the limit of my "play environment" and, again in my case, meant that I couldn't reach down and to the right without bonking my coffee table with the controller. Of course, I tried moving within five feet of the PS Eye – in front of said table – and was told that I was too close.

The definition of "too close" or "too far" changed on a game-by-game basis, too. One would say eight feet, another five and yet another 3.3 (one meter). Playing Move games in my den – a small room where I sit maybe four feet from the TV – was hit or miss."

So not only line of sight but the size of your play environment can cause trouble for the Move.  They did say that aside from those it the precision was extremely impressive.

The only glitching I noticed was with the Avatars. The direct stuff coming from the Kinect software showing the joints was following extremely well.  This tells me one thing. Kinect is working just fine, it is up to the software authors to interpret the data Kinect gives them and react correctly. So whoever worked on the Avatars responding to the data has some work to do.

It does look like developers are going to have to smooth over the output from Kinect, at least initially.  But with proper smoothing, the jerkiness will not be noticeable to end users.
