Researchers are trying to develop a passive lie detector that would study facial expressions, eye movement, and pupil changes in both visual and thermal spectrums to determine if someone feels guilty.
It's unlikely to be a panacea for the courtroom, or even job interviews, since it will never be foolproof, but it could be used to make initial guesses faster and more cheaply than by human screeners. That's why it's being looked at as a potential way to automatically screen for smugglers at borders. They say the technology may even have applications for computer gaming!
It's an interesting challenge to mix physiology, psychology, and computer technology and I wonder what the chances are that a passive computer-based system would rival the accuracy of predictions made with non-passive (wired) lie detector tests or those made by trained humans.
