Most lab setups I've seen involve a 'face cam' to capture user
reactions. Having run many sessions and captured them to video tape, I
can't say I've ever reviewed the face cam footage. The truth is that we
rarely showed anyone something that went so far as to elicit an actual
physical reaction that wasn't discernible from the audio track or their
on-screen mouse movements ("Oh my god! Run! It's a graphical DBMS!" was
a common reaction from CLUI-types, but never to the point of distorted
facial expressions or desperate grabs at the one-way mirror).
I wonder how much of the world of usability testing is a carryover from
'the way we've always done things' - we taped the user's reactions in
our sessions because there was a face cam setup in the lab and it was
standard protocol to insert a tape in the Face Cam VCR and a tape in
the Screen Converter VCR and hit record. To bring back the earlier
discussion about taping in a fresh new light: has anyone used their
face cam footage for a practical purpose?
