You know what this video proves? Nothing. Granted MS is glorifying some of the old capabilities as new. But can the Eyetoy/PS Eye do everything the Kinect can? Nope. Hence, this thread.

I mean Antigrav is likely just following  your arms as is the Nights game. The dancing games on the Eyetoy just require you to touch objects around the screen. Its not the same as Kinect at all.

 Except it's not 20 wii-mote as wii-mote camera see the actually spot while Kinect these points are added in by software. GT5 has shown PsEye can do head tracking in 3-D space by adding in squares around the eyes ,nose, mouth,etc. TrackIR actually tracks 3 IR spots to track in 3D space while PsEye uses software.  There are different ways of tracking something in 3D space including those suits with the white tracking balls.

The software helps create the points by using the 3D motion capture data from the IR sensor. This is what you don't seem to understand, watch the video from my earlier post, the sensor actually creates a 3D model of your body in 3D space. If you can't be bothered to watch the video then here is picture of a body (and a car and a rabbit, but I think they're just examples) as it's "seen" by Kinect's sensors: Edit. Pic won't embed for some reason so you have to click this link: http://3.bp.blogspot.com/_CPucYiWYXAQ/SiTIdxSJ9HI/AAAAAAAAAW8/qIriW4rzW5M/s1600-h/pointcloud.jpg

Like they said it's 50% hardware and 50% software. The IR camera does not actually sees in 3D like we do.

Yes it does, that's the whole point of it. WATCH THE F*CKING VIDEO OR CLICK ON THE LINK TO THE PIC! The IR sensor "sees" a 3D representation of what's in its vision and the Kinect/Xbox360 applies a 3D skeleton using the body shape (of whoever the player is, so it's customed to their body shape/size) as a guide and moves the skeleton via the motion capture data from the IR sensor as you move. The 10ft (or however big it is) "box" of the IR sensor's vision sees the floor, any walls that are in its vision and any object in fact (check out one of the videos of Your Shape where Kinect "sees" a jumper or jacket being taken off, this is in 3D IR not video) and that "box" is your 3D play area.

I'm too lazy to read through a 8 page thread that's probably turned into some fanboy war... and if it didn't I'm going to apologize right now.  Now on to the thread's topic what can Kinect do that the Eye Toy can't, that answer is actually limited to one thing; depth.  Now I hope someone posted the Dr. Mark's video where he actually demoed an early Kinect prototype on the PS2 cause I'm too lazy right now to look for them on youtube and I'll post them later if they're not in here.  Anywho what the eye toy lacks is proper 3d tracking so for instance if you wanna do collision it's all 2D.  So let's say the eyetoy is tracking me and there's a bunch of butterflies flying around the screen (I believe they used butteflies in the demo) if a butterfly gets behind me, it'll be an automatic collision with eyetoy.  With Kinect it won't be cause I'm being mapped in 3-space instead of 2.  That's pretty much the difference between the two cameras.  You can track 3 space with eyetoy it's just more difficult and you have to do trickeries, with Kinect it does it the real way with no smoke and mirrors.  But what can that actually do for gaming?  Quite a bit I'm guessing, it's more or less the jump from fake 3D in the arcades to real 3D in the... arcades. .  Sorry if I didn't explain myself properly when you see the videos it'll all make sense.

There is no need of getting upset.  What the sensor "sees" is the IR light bouncing off stuff (just like normal light) which is why Kiect at first had trouble reading people with darker skin. (they have claim this was fixed) The 10 ft limit has to do with the resolution of the camera. Higher the resolution the more detail (movement) a camera can pick up in the distance.

I knew it: the Eye cacks all over Kinect!     

Well, I think the new 360 is awesome, but we have no way of knowing how many of the recent resurgent 360 sales have to do with older model price drops at the moment.  Putting the 360 in a shiny new box is obviously appealing, but how many sales are due to people attracted to a shiny new box and how many sales are due to people buying off old stock at a lower price?  Yes, the shiny new box is the cause of it all, but we both know that price drops are appealing to everyone.  Ha ha, I guess this will never end.

I'm just fed up with seemingly every other comment on the internet about Kinect saying "It's just an Eye Toy." when only the video and audio part is like the Eye Toy. (And unfortunately not quite as good as the PS3's Eye Toy if those specs are accurate.) But the motion controller parts (although the videocamera can be incorporated into the control too) are the IR projector & sensor. Have you watched the video I posted?? The data from the IR projector & sensor is shown right there on the screen! It both senses the depth and creates what sort of looks like a dot matrix 3D image of the player and the surroundings. I'll quote some info about Kinect from the blog link you can't be bothered to click, he's an expert talking about it from a technological point of few not some tabloid magazine blogger saying "I waved my limbs about and the character waved its limbs about exactly the same as me! It was the most awesomest thing I've ever experienced!!!":

"Speaking as someone who has been working in interface and sensing technology for nearly 10 years, this is an astonishing combination of hardware and software. The few times I’ve been able to show researchers the underlying components, their jaws drop with amazement... and with good reason.

The 3D sensor itself is a pretty incredible piece of equipment providing detailed 3D information about the environment similar to very expensive laser range finding systems but at a tiny fraction of the cost. Depth cameras provide you with a point cloud of the surface of objects that is fairly insensitive to various lighting conditions allowing you to do things that are simply impossible with a normal camera.

But once you have the 3D information, you then have to interpret that cloud of points as "people". This is where the researcher jaws stay dropped. The human tracking algorithms that the teams have developed are well ahead of the state of the art in computer vision in this domain. The sophistication and performance of the algorithms rival or exceed anything that I've seen in academic research, never mind a consumer product. At times, working on this project has felt like a miniature “Manhattan project” with developers and researchers from around the world coming together to make this happen."
