Physiological data acquisition via USB

[David Glasgow]

OK, Timothy Miller's experiences seem fairly typical.  Monte's post hoc 
parsing is a bit more promising.

What I want to do is develop an existing rev project further.  I have 
folks sequentially viewing and rating images as part of a psychological 
assessment of sex offenders.  (Incidentally, after years of 
development, it is now working sweetly across platforms and is 
generating a fair bit of interest in the field.  Couldn't have done it 
without Rev! - or this list, for that matter)

What I would like to do is capture physiological data while they are 
engaged in this task, to see if there is any association between, say 
GSR and Heart Rate, and the ratings made/images viewed.  The problem of 
post hoc parsing is making sure that data is accurately matched to the 
corresponding image.  Ideally, the data would be gathered during the 
slide show and parsed on the fly (or maybe in the gaps between images).

What is really frustrating is, as Elizabeth Dalton pointed out in her 
post last year,  a somewhat 'new age' sounding game that costs $159 ( 
http://www.wilddivine.com ) does on Win and Mac what it seems 
impossible to do with equipment costing 10 times as much.


Best Wishes,
