Eye-tracking used in lie detection

Eye-tracking used in lie detection

Researchers have developed a new eye-tracking technology that could be a reliable alternative to the polygraph for lie detection.

The University of Utah scientists" eye-tracking technology measures a person"s cognitive reaction to lying, as opposed to their physical reaction, which is what a polygraph monitors.

Pupil dilation, response time, reading and rereading time and errors are all recorded by the technology when a person gives responses to questions.

One of the researchers, educational psychologist John Kircher, said that the technology had, so far, returned great results.

"They are as good as or better than the polygraph and we are still in the early stages of this innovative new method to determine if someone is trying to deceive you," he added.

The invention has now been licensed to local company Credibility Assessment Technologies.

On a related topic, researchers from the department of psychology at the University of Munster in Germany used eye-tracking technology to assess how drivers negotiate winding roads.
