kinect tracking suggestion

March 28, 2013 | 1:51 pm

hello max fellows,

i want to start an interactive project with the kinect.
the goal is to track 2 skeletons with my xbox kinect without doing the "psi" pose.

did a research and found out, that are many possibilities to do this.
mac versus win, openni versus mirosoft sdk, xbox versus windows kinect and so on.

i have tested several apps, which send osc messages with the skeleton data.

something as kinecta is what i am looking for:

http://kinecta.mihoo.de/

but it crashes often on my mac.

i am looking for some hints from people with experience at this field.
can someone suggest a simple and stable solution. mac or pc. (mac prefered)

thanks in advance,
pixelschub

jit.openni for Max is great.
SimpleOpenNI for Processing too.

or dp.kinect for windows works like a charm

thank you very much dtr and matmat for your hints !
i think i will go the jit.openni route.

dp.kinect is not an option, because it is not clear how much it will cost after the beta period.
information from the dp.kinect website :
"Current Beta version is v0.6.5 with an expiration date of 28 Mar 2013."

Hi everyone,

I didn’t think you could do skeleton tracking without the pose?

I hope I am wrong on this as it would be great!

can jit.openni do this?

with jit.openni it is possible.
i am doing it right now :-)

does anybody has made a simple 3d model (jit.gl.sketch?? ) in jitter, which represents the skeleton coming out of jit.openni ?

i have found: the Viewskeletons patch, but it is a bit different.

it is using ./osceleton as a input base.

What I do is simply put the skeleton coordinates in a 15×1 matrix and run that into a jit.gl.mesh in point drawmode. I don’t need more visualization than that. I’d share it with you but it’s embedded in a larger patch, no time to extract right now. Very easy to replicate though.

Btw, I’d largely prefer jit.openni to output the joints as a matrix rather than the messages it does now.
