Seems somewhat misplaced effort. Why isn't he using Move? It'll be more accurate. I suppose the background removal is the main benefit here from what he's saying, but then that's working at a very low res and is looking pretty ropey. The Kung Fu Live tech seems better suited for actual video compositing as it's higher resolution.
That does look cool, and I'm sure has the SW fans salivating! For a moment I thought it was supremely good tracking, but then I noticed in the mirror that the prop is the full length, and not as I first thought a short handle with the blade superimposed. This sort of thing, certainly the overlay, is fairly old hat, but the upside of Kinect would be 3D placement of the virtual sabre in the game. I wonder how well it tracks at speed? The demo was a pretty lethargic pace for a Jedi!Pretty cool Lightsaver vid.

At speed, it'll either work flawlessly, or fail misreably. If the rod is being detected per frame regardless of previous position, you'll get 30fps update just fine, and I image that's the case, but it may be that the tracking is much faster when a small delta is involved, and larger displacement require a full image scan which is slower. Ultimately though I'm not sure what Kinect is bringing to this sort of prop-tracking system which was already happening five years ago. With the 3D data, skeleton tracking might make it easier to locate and trace a prop, or if you know it's in front of the player you could perform a depth filter to isolate it more readily. Otherwise this doesn't seem new to me.Yeah, I was going to mention, that's slow as heck. We know that Move can do this at full jedi speed with no lag.
I hope they both get excellent implementations with no cheap ports, to really explore what the systems are capable of. Kinect should be able to incorporate some very realistic Jedi movements like a Force Push or levitations or lightning. The closest parallel I can think of so far is Harry Potter, which looked very rough last I saw.I think it's pretty much guaranteed though that both platforms will have their Star Wars games next year.

I wasn't comparing it to anything.
With lightsaber/sword games won't lag be a big problem? Like Streets Uncaged?
I imagine anyone trying to do Star Wars kid style moves will find the whole illusion break down very quickly as it will be impossible for Kinect to keep up.
Of course the other big problem with any kind of sword fighting game is that most players will just swing like mad because there's no feedback and so nothing stopping you from just swinging until your arms get tired (at least with fighting/action games you are input limited)
You guys do realise that you are comparing a homebrew with a poorly written driver with a full fledge game.
It's not the update frequency, but the lag. If the update from movement to display on character takes several frames, it won't be much fun.
I guess the biggest advantage is not needing any color segregation on the prop, which means any object can potentially be used, and not just the ones with fluorescent colors and previously known shapes/sizes (for extrapolating depth data).
Kinda makes me want to see someone doing this with just a stick. It will be interesting to see how much can just a depth sensing camera replace all the sensors on the move setup.
That's true of gesture recognition, but not of overlays like this SW demo. It'll just need to find the prop each frame. The concern then would be if the image was sharp enough or sufferes motion blur, which is an issue of exposure duration. If the exposure is 1/60th second, fast motions will be blurred and hard to identify. If exposure is 1/250th second, they'll be sharp. The framerate will be an issue for smoothness of movement; if Kinect were to update 10 fps, with a shutter speed of 1/1000th of a second, the images would be blur free but the player would see jerky movement making it a bit awkward. Lag is a third issue, the amount of delay between moving and the game updating with your movements. From user feedback it sounds like that isn't much of a problem.The slower the sample rate, the more likely it is to misinterpret movement. 60Hz sampling is going to be better, because there is less error in tracking the movement. I think 30Hz would be about as low as you'd want to go.
Essential DF article about USB speeds limiting Kinect. Makes yer think!

not trolling I have Kinect also but what you're asking for has already been done & is part of what lead to PlayStation move being made, besides the not needing a bright color & knowing the size before hand

& Sony has a patent on using real world objects with a Depth Camera to control games so I'm not sure if a dev can do that with a Kinect Game unless it bypass the patent.
It would be really cool to instantly benefit from a higher res camera without the need to buy a new for their next console...
