that's the beauty of IR - projected light isn't usually in the IR spectrum, so there won't be any feedback.
to have full control over the image, you might want to tape over the IR transmitter on the camera and use a more focusable IR source, like a couple of profiles with enough filters in them to cut all of the visible frequencies. i tend to use a dark blue, a dark red and a dark green, and have my lanterns at around 40%, focussed on the dancers but off the floor. its worth trying it with the in-camera transmitter first though.
LED lanterns are also invisible to IR, so if you need to change the light the space whilst tracking, its best to use these because they won't have an effect on what Eyes sees.
Faceshift was pretty fun to use, though in the spirit of full disclosure there's a lot of configuring to do to make sure that it works well. Native syphon support would have really made magic for us. Instead we found a decent work around with a virtual screen. We also made sure the model was on a background that we could key out from our media server - allowing to get some isolation of just the puppet.
I did quite a bit of research on pulse controller more than a year ago. I found how they did it and it is not doable in isadora. Well everything is doable but the sound analysis.
The sound object that does the trick (super fast attach detection) is called bonk~ and what bonk does is to analyze the attack of a sound coming from the piazo AT A SAMPLE LEVEL though 44.1000 times per second. That is it
There is another max/msp and Puredata object called fiddle~ that does a similar thin plus a bunch of other amazing stuff (like pitch detection).
Hope it helps. Sorry I can't be with you in Berlin in a fed days....
I know very little about sound design, I stick to lights and video. That said, I have no end of respect for the sound designers I work with and was as annoyed as they were to learn about the sound design awards being axed from the Tonys.
Anyway, I came across this excellent response from the creators of Q-lab; I think the sentiment crosses very much into our world as well so I thought I'd share it on here.
Sorry if it's a little off topic.

I am a recent Graphic Design BA graduate currently involved in an interactive project which requires Isadora software programming. The project focusses on the experience of Karaoke, and so requires pitch recognition through a microphone. Certain triggers from this pitch recognition, such as a screen which is playing an accompanying video going blank, or triggering a specific sound will be required. I am working with a group of architects on an interactive exhibition which is launching on 18th September until 21st September in Hackney. The curator of the show is currently in the process of applying for the show's funding.
I am looking for somebody who is highly capable with Isadora/sound recognition software and can help me achieve my goal, and is preferably London based. As my knowledge of this technology is minimal I am keen to see the project as a collaboration, and a healthy flow of ideas and suggestions from another party would be welcomed! As the funding is currently being applied for, if you are interested please could you also specify your daily rate and of course when the exhibition opens you will be credited in the project.
Please get in touch if you can help: email@example.com
and that way we can begin to discuss and I can explain to you what exactly it is I am trying to achieve.
Thanks and I look forward to hearing back!
