[PD] infrared camera

[yukio]

Hi, Do anybody have tried infrared cameras with pd/gem?
i made an installation for public spaces. using a web cam i tracked the
positions of people in a space(with pix_multiblob) then i send the
resulting coordinates to a processing program that create a graphic
representation of the people in a alife system, allowing people interact
with the creatures. In the first version of the installation i projected
the processing interface to a wall so people can see theirself in the
projection and can modify their positions in the real space to control
their visual representation.

What i want to do now is to project the processing interface to the
floor, so people can interact with the creatures in more direct way. The
problem with this is that it generates a feedback , because if i project
the interface in the same space that is being tracked , the system is
gonna track the projected images (retroalimentation) and it doesnt work
fine.
A friend of mine recommended to use infrared cameras , because they just
track the humans bodys and not the projections.
do anybody have tried infrared cameras with pd/gem?

which one do u recommend me? any hint?


many thanx for  the answers
