hello! I am having a problem, see if some of you guys have any idea... I need to trigger videos projected by tree projectors. The videos should be trigger by the subtle air or wind produced by the walking of the viewers on a room. The viewer will be surrounding by the 3 video projections. My first idea was to use video cameras connected with MAXmsp and create a grid to mark and read the movement of the people on the space. But, it will be better if is possible to measured the air produce by their movement, because conceptually works better with the video installation that i working on it. Any idea to how to resolve this? I was wondering if there is any kind of wind sensor that can be connected in to Arduino... IDEAS? I am really appreciated your help!

There are many other things you can do to simulate fluid/gas movement in a space once you have information about which way objects are moving in a field of view. If you take a look at some of Grant Kot's physics simulation videos here: http://www.youtube.com/user/kotsoft?blend=8&ob=5 (he was our intern here at QLabs!) you'll get a sense for what you can do with optical flow data.

Thanks a lot!! I will try with the three options that you guys send me, thanks a lot!!! As I will having questions or problems I will formulating them to you, thank you very much again. You are very kind geniuses!! Alexandra

Kinect sounds like fun in this situation. Also, you could opt for IR or Sonar rangefinders on a grid or in some sort of arrangement around the room as well.

Check Memo Akten's MSAFluid for Processing and Open Frameworks, for a fluid simulation that could be manipulated by CV and in turn manipulate the sound.

We've used the Kinect successfully to do more precise things where CV would normally be a good fit, because with the depth data we can easily filter out the background.

Presuming you're on a mac and have xcode, you'd download the latest openframeworks, go into the addons folder, then openCV, and open one of the demo projects in there. The vast majority of openFrameworks projects I've seen start from one of the demos and then tweak/build from there.
The ofxKinect package is very similar, once you've got the basics of working with openFrameworks down, it just provides depth data along with the pixels, which can be much cleaner to work with if you're using it to affect an interactive installation.
