 lie detection takes a high-tech twist there are markers in the eyes that are able to accurately determine if an individual is being deceptive the new test claiming to see the truth how it works and why the creator calls it better than old-school polygraph this is San Antonio's Fox News at 9 well they say the eyes of the window to the soul and one technology company believes they're also the most efficient way to tell if a person is lying Gabby Hart takes a look at this new technology that claims it knows if you're telling the truth 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 Neal Harris is the vice president of Converis the company that created this new technology called I 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 dilation 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 re 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 wanted to put both methods to the test so I sat down to see which machine would best read my line in the hot seat first we put the standard polygraph to the test slay asked me two questions that were simple enough to answer honestly I want everybody to watch the blue line is today Tuesday yes but before he even finished asking me the third question at work did you ever look at a boss with sincere eyes when you knew the reaction is already over but took off and it's barely coming back again then 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 eye 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 are answering what they perceive to be your question slay and Harris agree that both I detect and polygraphs can get it wrong sometimes there will be some false positives and false negatives with I detect as it exists today but Harris says the beauty of computer algorithms is that they get smarter over time I trust computers and algorithms far more than I would another human being still the polygraph remains a powerful detection tool not likely to be replaced anytime soon I think it's the age old argument of man against the machine big time technology company apple has taken notice of I detect apple purchased the sensor technology that's used to calibrate and read the eyes does this mean our iPhones could eventually become handheld lie detectors Harris says only time will tell I'm Gabby Hart reporting
