New Face Scanner Can See When We're Lying
A sophisticated new camera system can detect lies just by watching our faces as we talk, experts say. The computerised system uses a simple video camera, a high-resolution thermal imaging sensor and a suite of algorithms. Researchers say the system could be a powerful aid to security services. It successfully discriminates between truth and lies in about two-thirds of cases, said lead researcher Professor Hassan Ugail from Bradford University. The system, developed by a team from the universities of Bradford and Aberystwyth in conjunction with the UK Border Agency, was unveiled today at the British Science Festival in Bradford. This new approach builds on years of research into how we all unconsciously, involuntarily reveal our emotions in subtle changes of expression and the flow of blood to our skin.
