Is kinect tracking minuscule feet beats and very small wrist flicks, done quickly?

Its not a comparison, its another example...

If you're asking whether it can or not, yes. It can.

the custom hardware is for the hologram stuff the actual tracking is being handled by two wii motes, yes it needs custom software but so do all the kinect hacks for the PC it theory with some slight modification that software could work with any two IR cameras there isn't really anything that special about the kinect, any amature hacker could achieve it. 

here is a guide http://3dbruce.blogspot.com/ just replace the cameras with IR ones and start working on modifying some kinect drivers and you are set, have fun.

Example of what?

I can put up a video of someone kicking a ball with Kinect Sports which the Wiimotes can't detect, but it has nothing to do with their ability to simulate drumming. 

What is your comparison, that both systems have musical applications?  Because I think his point was Kinect's ability to track finger movements, not that a musical app of some kind is possible with Kinect and not with any other console system.

I guess I'm just getting old.

I don't get the appeal.

Although I do like that video Barozi posted. That's pretty cool. Kinect is going to be big on youtube

In another 6 months, I think the Xbox haters will start to have exploding head syndrome with fits of jealousy and rage…how can the Xbox get this…lol…look at me, I can do it too…not really, but I will say I can!

Anyway,…back to the OP topic, this is a really impressive example of Kinect’s potential.  One thing I notice was how rapidly the tracking was for his movements to the on screen action.  Granted, this is graphics aren’t anywhere as complicated, but I think with more time, and experimentation, developers will be able to drastically improve the performance of Kinect, and deliver lightning quick tracking for more fast twitch action.

The hackers are making custom software but it is the kinect itself that is tracking the movements of the person in 3D space and converting it into digital information. The hackers are simply taking that information and applying it to their own software.

Also you are severely underselling how hard it is to make a 3D capable tracking camera. You need far more than just two IR cameras and some software, not to mention the software has to be quite advanced.

Also what were you trying to prove with that link? Unless I read it wrong all that is showing is how to make a camera that can take 3D pictures, it has nothing to do with a camera that can track movement in 3D space.

I think you are ridiculously underestimating how difficult it is to make software capable of tracking specific body parts like head, arms, fingers and legs in 3D space. This is not something that can be done by some amateur hacker.

If it is so easy can you show me a video or article of someone using a wiimote to create a 3D camera with full body tracking, I am honestly curious?

not quite as sophisticated as kinect but

Once hackers start porting over the kinect libraries the tech should come in leaps and bounds 

I should clarify I do think that Natal (especially the libraries they developed) is an impressive piece of tech but it's not exactly unique or un emulatable it is esentailly a webcam a couple of IR cameras and some very impressive libraries.

Kinect only works at 30 fps, that's why it has a considerable ammount of lag, I don't think it could recognize you drumming an imaginary drum set at the speed thisguy is drumming. Plus, he's sitting, another let down, you have to be standing for kinect to work with skeleton tracking...

Seriously, if you're going to keep discussing Kinect I'd suggest you do at least a bit of research....this was fixed months ago.  I've played Joyride while sitting just fine.  They simply changed the root tracking joint from the base of the spine to the neck.

Secondly the lag, or latency to use a more correct term, of Kinect is only about 200ms, and that's after having to all the computational work to render a scene and animate a character.  The raw data has extremely small perceptible lag.

You other point about drumming is still baffling, why is this even relevant to this thread?  I can guarantee you the lag with Wii kick tracking is FAR worse than Kinects drum tracking.  I think you'll be waiting years for your kick to register with the Wiimote in your hand.  Again though, it's completely irrelevant to the topic.
