Couldn't you do this with any webcam and CV? I don't see how the depth component makes it any easier.

As far as I understand, depth values make the blob detection easier. Normally blob detection tries to use the brightness differences caused by 3D objects - depth values make it much accurate.

Wouldn't it be better if he was only holding a small 6" long stick, the kinect tracks that, and digitally adds the extended lightsaber? Maybe this was just his step 1. It would minimize the destruction caused in your home from swinging around a 4' stick.

The full length stick works better for duels. Filming cool duels is pretty much what this thing screams to be used for. Of course to minimize damage, you could probably use something lighter than a solid wooden stick.

Full-length duals have already been done, though. I don't think that is the killer application of this tech.

Maybe you could use the wiimote in combination with the physical tracking to get more precise telemetry + precise physical location and AR.

That was my thought a week ago. The kinect is limited in that it can only see the front of your body. Some movements obscure your body and it basically just freaks out.

...if by "real time" you mean delayed by 200ms.

In graphics terms when someone says 'realtime' they usually are referring to the performance of the algorithm, not whether or not there's a delay. Lots of video games have input delays of 100ms or more.

The framerate is pretty bad, though. I wonder why - I was under the impression the Kinect captures at 30fps.

this is a potential killer application. if they manage to make the tracking fluent and accurate, everybody can finally duell other players in epic lightsaber fights. anyone who liked star wars has probably been waiting for this - let's see who gets it right first - PS3 Move, Kinect or even Wii?
