How does EyeDetect Work?
EyeDetect uses both an infrared optical scanner and complex algorithms that work simultaneously to determine a Credibility Score.
The human body responds in many ways to the stress of deception; the greater the consequences of the lie, the greater the stress. The changes of the eyes reflect stress and cognitive effort. The optical scanner measures changes in pupil diameter, eye movement, eye blinks, and fixations.
The person being tested sits in front of a computer and uses a chin rest to stabilize his or her head. After being calibrated to the optical scanner, the person answers a series of true/false questions.
The question responses, along with pupillary changes and eye movements are measured and are stored on a secure, encrypted data locker. Only authorized personnel can access the report through a Web browser or mobile device to view individual tests and the Converus Credibility Score. This score is the probability that the person was truthful.
