How Does EyeDetect Work?

EyeDetect Station

The brain and eyes respond to deception. The greater the consequences of the lie, the greater the cognitive load. This affects the eyes. EyeDetect measures changes in pupil diameter, eye movement, reading behavior, blinks, fixations and other things.

Using an infrared camera and complex algorithm, a person’s credibility score is calculated: truthful or deceptive.

Participants answer True/False questions on a computer. The infrared camera records eye behaviors.

When the test concludes, responses to questions and eye measurements are uploaded to a web server for immediate scoring.

Those authorized can view results in the web-based Converus Dashboard. A Converus Credibility Score shows the probability the person was truthful.
