You can’t hide your lying eyes. At least you can’t hide them from a new computer which tracks eye movements and can detect untruths more than 80 percent of the time. That’s nearly 20 percent more accurate than even the most experienced interrogators.
Inspired by studies which measured the movements of the human face for clues that someone is telling a lie, the new automated system tracks only eye movement. The system tracks how people moved their eyes in two distinct situations: during regular conversation, and while fielding a question designed to prompt a lie.
People whose pattern of eye movements chang between the first and second scenario are assumed to be lying, while those who maintained consistent eye movement are assumed to be telling the truth. In other words, when the critical question is asked, a strong deviation from normal eye movement patterns suggested a lie. Follow up questions verified results of the testing.
The research suggests that computers may be able to learn enough about a person’s behavior in a short time to assist with a task that challenges even experienced interrogators, simply by tracking eye movement. The videos of subjects included in the study showed people with various skin colors, head poses, lighting, and obstructions such as glasses.
Interrogators say the use of eye-movement technology provides another valuable tool in the ongoing search for finding truth.
