Physiological data acquisition via USB

[Thomas McGrath III]

I've seen the Wild Divine project before and it tries (not well) to 
allow a biofeedback  to control software. It does not seem like this is 
what you want. It sounds like you want feed back from instruments along 
with a Rev project.
This can be done using a serial device called an I/O and some 
instruments. A USB to Serial converter like the Keyspan Highspeed 
Serial Adapter (Must be Highspeed)is used to plug in an old serial 
versions or use a straight USB like what the Telio uses.
There are a few devices out there. There is the EZIO and the HandyBoard 
as well as an old one called MacBrick. There is a real old one called 
ADBIO (OS9) and of course there is the Lego controller which offers a 
limited I/O and more advanced if you want to hack the Lego modules.

  My research has showed that the most promising one seems to be  the 
Telio by MakingThings from http://www.makingthings.com/ . This is a 
modular Input and Output system that has both analog and digital inputs 
and outputs. The Digital inputs can read a variable voltage or a signal 
converted to a variable which is what you would need. The analog ports 
are good for simple on/off signals. They offer a few different modules 
that can be piggy backed to allow for more devices to be connected. The 
Telio sends and receives serial wrapped commands. The site offers 
libraries in Flash/Director/C and Real Basic but so far none for Rev. 
You would have to wrap your own.

The Rev project would (at points chosen by you) monitor the Telio via 
the USB cale and any sensors you have plugged in and report back that 
info. You would then store that info with a tag for the slide you are 
on and later do some analysis with the data. The hard part is the 
wrapping of the serial commands.
