A team of British scientists have developed a sophisticated new camera system that tries to detect if someone is lying. According to an article from BBC News, "The computerized system uses a simple video camera, a high-resolution thermal imaging sensor, and a suite of algorithms." The new device depends on the fact that we give our emotions away through bodily cues—eye movements, dilated pupils, biting our lips, wrinkling our nose, breathing heavier, swallowing, or blinking.

The researchers conclude, "We bring together all this well-established work on expressions, these recent developments in thermal imaging, techniques for image tracking of subjects, and our new algorithms into one operational system." However, they also acknowledged that all of these scientific discoveries aren't 100 percent accurate. When the article was written, they could discriminate between truth and lies in about two-thirds of cases.
