New Eye-Monitoring Lie Detector


Soon sex offenders nationwide may be examined for any parole or probation violations by a new lie detector that monitors eye behavior to detect deception. EyeDetect is the world’s first nonintrusive lie detection technology that accurately detects deception in 30 minutes by analyzing involuntary eye behavior.

Unlike a polygraph, an EyeDetect test is nonintrusive. The person being tested sits in front of an EyeDetect Station, which is a computer equipped with a high-definition, infrared eye-tracking camera. The eye tracker is calibrated to monitor involuntary eye behavior — including pupil dilation, blink rate and other eye movements — and to administer the test. The test takes 30 minutes and provides a “truthful” or “deceptive” score in about 10 minutes.
