 Well the eyes are said to be the windows to the soul, but in this case one local company says they can tell so much more. They've created a lie detection system based on the involuntary movement of your eyes. News 10's Brianna Berry has more. It's often said you can tell if a person is lying based off their eyes. One Lafayette man is putting that theory to the test with a lie detection system based off the human eye. In 1921 the lie detector was invented and there hasn't been a tremendous amount of increase in that technology until now. The technology called Eye Detect uses an infrared eye tracker to monitor involuntary eye behavior such as pupil dilation, blink rate and fixations. To detect deception in 30 minutes while a person answers true or false questions on a computer. The theory with this system is that it takes more cognitive work to lie than to tell the truth. Roy CEO of Global Data Fusion held a special demonstration at Don Sifu downtown. You can mass screen people, so for example in the counterintelligence world all of the people that are applying for visas from Syria that want to enter the United States. We can sit them down and within 30 minutes tell if they are terrorist or if they have terrorist ties. Anyone willing to take a shot on the test chose a number and it was asked a series of questions. Roy promised $100 to anyone who could fool the test. I retired from the Lafayette Police Department and I was their polygraph examiner from 1988 until my retirement in 2006 and I took the test, it's very benign, the instructions are very easy, very simple for anybody to understand. They picked my number, I mean I did what he told me to do and he picked the number so I've known other people who have taken it also since then and that $100 bill is still sitting there. Field tests show Eye Detect is 85% accurate but when used with the polygraph accuracy it's 97%. In Lafayette, Brianna Berry, Kalef, Y News 10.
