 lie detector when a human being is being deceptive that there are these micro dilations of the pupils how it works focused on lying eyes they say the eyes are the window to the soul and one tech company thinks they're also the most efficient way to tell if you're lying new at 11 Gabby Hart reports a new form of lie detection claims it can see the truth there are markers in the eyes that are able to accurately determine if an individual is being deceptive Neil Harris is the vice president of Converis the company that created this new technology called eye detect it uses only the eyes to determine if a person is lying when a human being is being deceptive that there are these micro dilations of the pupils it's the extra mental energy that it takes to be deceptive I detect has been in the work since 2003 only taking 30 minutes to complete this new testing technology could be faster and more efficient than the old-school polygraph its creators argue that I detect may have the edge because it isn't influenced by any human bias so by removing the human element we believe we can make the assessment of credibility far more forensic in nature Ron slay is a security consultant who administers polygraph exams he says in his 40 years of experience he's seen all forms of deception and he thinks it takes more than a computer system and answering a few questions to detect a lie you can't automate the human mind we tested I detect Harris had me write down a number between two and eight and then hide it I chose the number seven the examiner told me to lie about my number to the machine but to tell the truth on all the other questions as the I detect system calibrated my eyes and then monitored my pupil dilation I did not choose the number seven it was not the number that I picked look at the spike on the seven safe to say that I got caught lying or preparing to lie on both tests but slay says it can sometimes be harder to catch the people you want to catch because they have their own truths they're not really answering your questions at all they're answering what they perceive to be your question slay and Harris agree that both I detect and polygraphs can get it wrong sometimes still the polygraph remains a powerful detection tool not likely to be replaced anytime soon I'm Gabby Hart reporting I detect says it hopes the technology will have a positive impact and potentially give law enforcement another tool
