There is a saying 'The eyes are the windows to the soul'. Expression of the eye can indeed reveal many things. One of them, the eyes can be a clue to find out whether someone is telling a lie or the truth.
Using this concept, a team of psychologists in Utah, USA, work carried out new research polygraph (lie detection), which relies on eye tracking technology to detect lies.
As quoted from page Aol.com, the proposed device will measure eye movements that accompany the response to these questions to determine whether they lied or not.
