K Thx, bye.  I don't mind, you admitted you posted a bad opening post, took 8 pages, but we got there.  Thanks for playing.

You're clearly new here. Stop making a fool of yourself. Solid_Snake4RD merely posted this speculating on the similar performance of both technologies with some video evidence to back up his claim.

You talk about 3D depth perception that Natal has over the eye with it's two cameras, but there aren't any videos showing games using depth perception, all there has been so far is motion tracking which the eye clearly can do.

The only accurate depth perception I've seen is with the move controllers and one camera. And there's video proof of that working effectively and usefully in a number of move titles.

So please don't bite on non-existent bait and turn this peaceful website into another fanboy warzone.

Every single Natal video using Ricochet uses 3D depth perception.  How hard you hit the ball is determined by your arm speed going forward in the air (or legs).  Also when the guy demoed the paint program at E3 last year that showed you 3D depth perception in motion when he chucked the paint at the scene.

Naw, I'm not new, not at all.  I am what you call a lurker.  And to be honest, I didn't want it to turn into this, and as I said, if the opening post had a bit more info it would have been fine, but I've covered everything, and you don't want to read it (I mean, its a of bs to read thru now to find the small nuggets of information ;)

Fair enough, they just didn't seem all that depthy to me  maybe I need more gimicky stuff like someone throwing a tennis ball really softly or really hard. Or maybe I'll just have to wait until I can give it a shot

I know what you meant, it is hard to see the depth perception in action when people wave their arms like lunatics.  It would be better to see someone picking up objects in a 3d space even if just a tech demo to show off the tech.

You are right about one point , Eye can also do 3d depth perception just like Natal. Natal has an extra IR camera while Eye uses normal colors which means it need something like Move ball to gain more accurate 3D perception. The Move ball predictable color and size makes it easier to program and track. Even Natal at the beginning had trouble with tracking people with different skin tones as this affect on how IR light bounce off their skin. (Microsoft claimed this was fixed)

That's not true 3D depth perception, the camera uses the perceived size of the ball  to gage how close or far away it is. It also cannot track things as small as fingers, and it's definitely different than Natal. 

umm yes it can, though the lighting must be real good to do so , that's one of the main reason's why the lighted sphere on the playstation move is there because not everyone will have real good light in the room where the EYETOY is going to be . thus with a lighted sphere it make's it much better for the EYETOY to track the move. or body part's and motion's of a person, yes The 3D cam's that in Natal are better at it than The EYETOY, the EYETOY can indeed track small object's like finger's.

example:

The most interesting of the demos came from Richard Marks, Manager of Special Projects at Sony Computer Entertainment America, and involved his increasingly popular EyeToy.

The first demo highlighted a “View Tracking” system that allows the EyeToy to adjust the in-game camera based on movements of the player's head in space. Marks played a first-person shooter for the audience, and when his character came to a corner, he was able to “duck” his head around for a brief peek at his opponent. View Tracking uses about 25% of the CPU power of a PS2, Marks said – but less than 1% of the power of the PS3.

The second demo featured a gestural interface in which the EyeToy tracks and translates a user's hand motions, based on simple color keying. Holding a simple wedge of neon-colored Styrofoam in his hand, Marks was able to select and rotate objects in the game, effectively turning his hand into a spatial mouse. In addition to eliminating the need for gloves or other devices, he noted that this allows the EyeToy to track multiple objects at once, allowing for two-handed gestural control and other gameplay innovations.

Sony has filed a patent number 2006-178948

“Basically, a camera will recognize every move and position of an object and will translate these actions accordingly to an object inside a game. Via this new technology, the 2D camera is analyzing an object in full 3D through a patented mapping technique.

Until now, more than one camera was needed to capture an object’s movement in 3D.

both Natal and the EYETOY DO THIS

PS eye cant do what Natal will do: Actually SELL (lol)

MS spends 4x the advertising money as Sony does in gaming. For every 1 PS Eye ad your gonna see 5 Natal ads.
