Whether it’s brainwaves, skin temperature and conductance, heart rate, perspiration, pupil dilation, facial muscular contraction, or something else, the various methods of measuring biometric response for market research seem to be here to stay.

Are you using any of these methods for market research?  If not, tell us you’re not (and maybe why). If you are, tell us which methods you’re using and for what purpose (e.g., ad testing?  website testing?).  Are you satisfied that you’re learning what you wanted to learn…and at a reasonable cost?  Let us know!
