Researchers have developed a new lie detector method using the Xsens MVN motion capture system to monitor full-body motions.
The polygraph is beloved of the movies, with countless dramatic moments showing the guilty sweating profusely as they are hooked up.
But the invention could soon be defunct. Researchers in Britain and the Netherlands have made a breakthrough, developing a method with a success rate in tests of over 70% that could be in use in police stations around the world within a decade. Rather than relying on facial tics, talking too much or waving of arms – all seen as tell-tale signs of lying – the new method involves monitoring full-body motions with the Xsens MVN motion capture system to provide an indicator of signs of guilty feelings.
