New Lie Detector System Uses Thermal Imaging
Posted on September 13, 2011
CNN reports that UK scientists have created a new lie detector system that uses dual cameras. The cameras include a thermal imaging camera to monitor heat changes in a person's face. The scientists say the thermal camera can detect heat changes that indicate a person is anxious and possibly lying. A second camera tests for visual cues, such as lip biting and blinking.
The BBC reports that 30 to 40 subjects have been tested so far with a two in three success rate, so about 33% lied and were not caught by the new system. Take a look:
