It sounds like you are asked about a device...there are some face readers
out there that supposedly detect different facial expressions, including
frustration, but I doubt they would be practical or affordable for a
usability study and I also don't think that they would quantify anything
(instead
Participation it's the key attitude for knowing the results of your
testing, just overview the users, ask them, make a form, think the
possible deviations of the responses. In the limit make the users
design your product. If not the users just will transform them into
their best personalisation
For clarity, could you tell us whether you're looking for something
that provides feedback in real time the way, say, a lie-detector might
work?
Yes, I'm looking for something in real time, rather than asking the user
at the end of the test what they thought of the application. As Robert H
I'm no usability expert, but I guess that recording people use the
applications and then analysing and timing the behaviour is the way
to go.

The simplest way is to show the users a set of emot-icons e.g. *:)* (happy),
*:| *(neutral),
*:( *(sad), *:s *(yucks!, bad), *:p *(oops!, confusing), etc. Ofcourse this
has to graphically treated (try yahoo or msn icons). Once the user completes
a task, he/she can circle/tick the appropriate task

I was wondering if any of you has had experience using a tool to
quantify the frustration of the user while using an interface (in our
case a web application or website). This tool is to be used during
usability testing, of course.
Do you have any links to research, products and samples?
Gee, I just love quantifying qualities /irony But, in this case,
have you considered adapting the medical Wong-Baker visual pain
scale? there's a pretty good article on it at
http://en.wikipedia.org/wiki/Pain_scale
there's a 10 point measurement at
