How to track a point as in "adaptative use instruments"? (and more)

January 10, 2008 | 3:38 pm

hello!, Im a max/msp user, but totally new in jitter... I have some ideas (all of them about controlling audio and max data with my body) and would like to know if that nose tracking showed in "adaptative use..." is possible with jitter, and if tracking a point of your body (hand, nose, a point in the shoulders)and get its data (x,y,z) is something difficult to be done.

by the way… have you seen johnny`s work?

http://www.cs.cmu.edu/~johnny/projects/wii/

does anybody have patches of something like this for mac?

…so, would be this kind of things be able to be done with jitter?

to many things, I know!

thank you so.

thanks for sharing this great link.

to do tracking you may want to check the cv.jit library based on openCV
http://www.iamas.ac.jp/~jovan02/cv/
there are some great tracking objects.
you probably know the aka.wiiremote object if you want to explore tracking with the wii as showed in the link you posted.

for three dimensional tracking you may have to use orientation sensors such as

if you want to track hands, for instance, have a look at this

a simple hack, not to be mistaken with an opencv object,,,

hello and thanks… the openCV library is too much, Im allways surprised with the things one can find in the web and in forums like this, keeping in mind that this library can be a work of years... and theyre sharing it by free!.

…I work so much with magic aka.wiimote object, but as I know it can not receive ir data, CAN IT?. and after that I should develop by my self all the applications that johnny has allready done… I am a dancer, hes a "computer science" gifted investigator, It will be better if I follow his discoverings (Im seriously thinking of buying a pc just to learn and try all those experiments).

regarding to sensors, for the moment I prefer to investigate in visual motion tracking (cyclops for example), as it`s much easier (and cheap!) to dance with no cables and machines over your body.

thank you!

david
