I watched this and wanted to try something similar.
Any of you working with "augmented reality"/camera input stuff?. Do you have any useful sites/tutorials/source code for the path camera-->imageprocessing-->3d coordinates/rotations, else than the stuff on artoolkit?

I have used ARToolkit some years ago and built a GUI system on top of it (video). This was also later turned into course material, so it is quite well documented (in German).

Other than that, there are ARToolkitPlus, ARTag, and OSGART (which is the latest thing from the guys behind ARToolkit), and integrations of ARToolkit(Plus) with Director (Dart) and Virtools (VirToolKit). Also OpenCV might come in handy if you intend to roll your own thing.

Hope this helps.

I think doing it with a camera is unnessesary .. thought about doing it with 2 wiiremotes .. like that head-tracking stuff I saw on the net !! Anyway .. don't have one .. but I think its easier using location in space .. than shape detection of the camera pics !! But I don't really know if its possible in 3D space ?!

Now think about that ;)

I would take an arduino and connect a few wires to my brain and code some stuff on the arduino to make stuff move.

Thanks for the links.

Imo the camera thing is way more convenient, as every laptop has a builtin camera now (at least usable for the head tracking) and webcams with decent quality are dirt cheap nowadays.

I'm currently working on an augmented reality game. (School project)
We use VirToolKit which works like a charm, it's basically ARToolkitPlus wrapped in a virtools building block. As much as I hate Virtools, it was the only engine I could find in which AR could be easily implemented.

Only drawback is, it won't work with the Virtools 3D Life Player because virtoolkit requires a custom building block DLL. The player can use only stock building blocks.
So we had to build our own standalone player (quite easily done with the virtools SDK).

I've tested it with up to 36 simultanious markers using a 960x720 webcam. It runs at around 30fps.

Very cool one I've found by coincidence: http://www.youtube.com/watch?v=Y9HMn6bd-v8

Speaking of cool stuff, I found the work of Lepetit et al. from Lausanne on vision based tracking particularly impressive, e.g. BazAR library, links to videos and papers.

While browsing the page of Lepetit with my morning coffee, I found a comprehensive survey paper on model-based tracking of rigid objects that I didn't know of before. It might be just what you are looking for at the moment.
