 Turns out your eyes do give you a way after all. When we lie, it takes more mental effort, more energy. And that energy causes our pupils to dilate ever so slightly. You can see this change with the naked eye. But according to researchers, it happens every time someone lies. Now a company called Converis is giving this pupil change a closer look with their eye detect. A device they claim can catch someone in a flat-out fib just by looking at their eyes. I will be watching you. Eye detect uses a very precise infrared sensor, and they can measure pupil dilation down to a hundredth of a millimeter. This ocular technology might be new, but just like the good old-fashioned polygraph machine, it all starts with a simple question. Have you ever watched pornographic videos? Well, not necessarily that one. When we're asking questions of an individual, we can determine if they're being deceptive or truthful, based on how much pupil dilation is occurring immediately after they answer the questions. Tell me the truth. If the pupils bug out, liar, liar, pants on fire, and speaking of the heat, Converis claims their new lie detector could one day assist police with keeping an eye on crime. Our hope is that our technology can help make us safer and help protect us from those that would want to cause harm. Truth be told, eye detect looks good to us. So, until next week, stay...
