 On the News at 6, new lie detector technology that works by looking you right in the eye. Find out how local police plan to use it. One, from Idaho's News Channel 7, this is the News at 6. Good evening. You've probably heard the saying, the eyes are the window to the soul. And now scientists are proving that in a way with new lie detection technology. It's called eye detect. And the test gauges whether someone is being deceptive based on eye movement and eye behavior. KTVB's Gretchen Parsons got to see how it works today, so tell us Gretchen, what's it like? D, unlike a polygraph test, you're not hooked up to any wires or sensors, and there's no examiner that's in the room with the subject. The test is completely automated. The Boise Police Department just recently began using this technology to screen job candidates. Other Idaho agencies, including the Department of Corrections were at the demonstration today to see if they could also implement eye detect. There are physiological markers in the eyes that give insight on whether someone is being truthful or deceptive. So how do you detect that? Basically, the subject sits in front of the computer alone and answers a series of questions. Some questions are neutral and others are to see if the person is being truthful, such as, have you ever used illegal drugs or have you ever been convicted of a crime? While an infrared monitor observes the individual's eyes. The infrared sensor takes 60 measurements per second of a wide variety of variables in each eye. Eye detect uses 16 markers in the eye that correlate with deception. That's according to scientists at the University of Utah who helped develop the test. One of the strongest is pupil dilation, but we also look at blink rate, eye movement, where the eyes fixate, which words they fixate on and other factors. For a demonstration, Harris asked volunteers to pick a number and purposely lie while taking the test to see if their deception was detected. And it worked. James Page, a polygraph examiner with Astartane Polygraph Services, says this fully automated test is a very useful alternative when a polygraph test isn't the best option. Polygraph is a technology that requires the skill of an examiner, somebody who's highly trained, they have special education. The test takes 30 minutes and results are ready in five minutes. Along with the poise police department, Harris hopes more Idaho agencies will get on board. It's anyone that wants to know the truthfulness of another individual. The eye detect is used in 34 different countries around the world, primarily in government and law enforcement agencies. Fascinating to see it Gretchen. Thank you for showing us.
