 I'm Bill Evans. I own Polytech Incorporated. We have an office in Cleveland, Ohio and Akron as well. I teach at the University of Akron. I'm also a licensed lawyer in the state of Ohio. The polygraph has always been a gold standard for lie detection. It's been around a long time, 100 years. And new technology is always somewhat suspect. I waited a while before I actually bought into the science, though we knew for a long time that ocular lie detection, pupil dilation, was an accurate means of assessing truth or deception. It was difficult to evaluate and identify how that pupil dilates. At about 60 frames per second, we can determine how much that pupil dilates, up to one-tenth of a millimeter, very accurately. And then in correlating the accuracy of polygraph and eye-detect ultimate decision making on people that are tested, we were able to determine that eye-detect was an accurate way of identifying a person who's actually telling the truth or not. The way we did that was by pairing some of the testing of polygraph cases, specific issue cases, whether it be a murder, whether it be a burglary, whether it be a car theft, whatever type of case it may be, identifying that person's credibility or truthfulness as to whether they were involved in that crime, and then subsequently testing that individual with eye-detect. Now there were times when we used eye-detect in the beginning, at first, before we would run a polygraph. The interesting thing about that was by the correlation of the accuracy of lie-detect when we would test the person with the ocular type of technology, we would have an opinion, and I wouldn't look at that opinion right away. I would go and I would test that same individual on polygraph, see how the person tested with polygraph, and then go back and get the results of the eye-detect. So in the beginning, I wasn't sold right away on accuracy because I wanted to evaluate it myself to determine whether or not it was correlating with polygraph. It was. So the interesting correlation existed for me, and then the researchers and the scientists at eye-detect were able to identify that by comparing polygraph technology and eye-detect technology and comparing and combining their accuracy together, we were able to raise the confidence level to about 98%. That was a really big factor in making a decision within our department, within our agency, I should say, of polytech as to whether or not we were going to use them both in paired testing.
