To identify liars the software keyed on behaviors such as looking directly at the questioner, speaking with more vocal fill and counting gestures.

To identify liars the software keyed on behaviors such as looking directly at the questioner, speaking with more vocal fill and counting gestures. Professor of computer science and engineering Rada Mihalcea said people focus on higher levels of communication and as such are poor lie detectors, because "We're not counting how many times a person says 'I' or looks up."

If that's not enough of a reason to get your story straight, the team says it's working on ways to tie in "heart rate, respiration rate and body temperature fluctuations," all measured by thermal imaging, without even touching the subject. The other big step they're working on is letting the computer classify gestures itself -- similar to technology explored by researchers in Finland -- which is currently done by the researchers. Your hidden tell may not be hidden for much longer.
