 This is KSL News at 6. Eye detect detects when people are lying by analyzing subtle changes in the eye. The future of lie detection has already been adopted by several law enforcement agencies in Utah, and it was developed right here in Utah by a company called Converis. Essentially, eye detect looks at pupil dilation, blink rate, and other reading behaviors so to determine if someone is telling the truth.
