 WQAD, this is News 8 at 11. You're out of the windows to your soul, but what if they could also be an indicator of truth? Kim Kung shows us the new technology that uses your eyes to show others if you are being honest. Our eyes, they can show joy, sadness, anger. They can also show lies. Can you tell if a criminal is lying? What if you could identify a terrorist by looking him in the eye? Or maybe it's as simple as knowing if your spouse is lying? I can tell because there is a lag in response. Sherry and Scott Sprouse have 20 years of marriage under their belt, but they know the signs. She's a horrible liar. That is true. What about trained law enforcement officers? There are things people have said and that when they say it, as an investigator, you're sitting across from them and immediately bells and whistles in my head go off that this person's lying. Unfortunately, that isn't always the case. Can we ever truly tell if a person's being honest or trying to be deceptive when they're going through an interview? We can't. But what if a cutting-edge technology can tell if you're lying by monitoring your eyes? It's called eye-detect and is the world's first non-intrusive lie-detection technology. In 30 minutes, it'll say whether or not you're being honest and it's 86% accurate. Here's how it works. You sit down in front of a computer loaded with the eye-detect software. Then a test administrator makes sure your eyes are lined up. You wrote down seven? Clearly. I'm a horrible liar. As you started to get closer to seven, your reading behavior likely changed because you were preparing to lie about the item that was going to be presented. The lie-detection test will continue. This eye tracker captures up to 16 measurements per second, including the slightest pupil dilation. It takes more effort to tell a lie than to tell the truth. And that increase in mental effort, even if it's slight, that slight increase in cognitive load has an involuntary effect on the eyes. So look into these eyes. Are they lying? Is there an underlying motive? There are hundreds of eye-detect tests ranging from catching cheating spouses to identifying violating sex offenders. We have some countries, some governments that are using it to verify people who are coming into their country that are suspected of having ties to terrorism. Believe it or not, the U.S. government is almost the last of the parties, so I think it's time for them to step up to the plate. One thing that the president indicated was increased vetting immigrants from certain countries and refugees. This is a perfect tool for that. That's why eye-detect was developed. We saw this as an opportunity to use technology to make the world a safer, less corrupt, better place. All because the eyes don't lie. An eye-detect machine costs $4,000 and then charges a fee for each test. Some law enforcement departments and private investigators have already started using eye-detect.
