On the 5th of January this year we presented a paper on the automatic detection of deception based on full-body movements at HICSS (Hawaii), which we blogged about here at LBT. We measured the movements of truth tellers and liars using full-body motion capture suits and found that liars move more than truth tellers; when combined with interviewing techniques designed to increase the cognitive load of liars, but not of truth tellers, liars even moved almost twice as much as truth tellers. These results indicate that absolute movement, when measured automatically, may potentially be a reliable cue to deceit. We are now aiming to find out if this increase in body movements when lying is stable across situations and people. Simultaneously, we are developing two lines of technology that will make this method more usable in practice. First, we are building software to analyse behaviors in real-time. This will enable us to analyse behavior whilst it is happening (i.e., during the interview), instead of afterwards. Second, we are investigating remote ways to analyse behavior, so interviewees will not have to wear a body-suit when being interviewed. We will keep you updated on new developments.
In the meantime, we received quite a lot of national and international media attention. Here is some tv and radio coverage on our work by Dailymotion, Fox (US), BBC world radio, Zoomin TV (NL), WNL Vandaag de dag (NL, deel 2, starts at 5:20min), RTL Boulevard (NL), Radio 2 (NL), BNR (NL), Radio 538 (NL). Our work was also covered by newspapers, websites and blogs, including the Guardian, the Register, the Telegraph, the Telegraph incl. polygraph, the Daily Mail, Mail Online, Cambridge News, King’s College Cambridge, Lancaster University, Security Lancaster, Bruce Schneier’s blog, International Business Times, RT, PC World, PC Advisor, Engadget, News Nation, Techie News, ABP Live, TweakTown, Computer World, MyScience, King World News, La Celosia (Spanish),de Morgen (BE), NRC (NL), Algemeen Dagblad (NL), de Volkskrant (NL), KIJK (NL), and RTV Utrecht (NL).
