Converus EyeDetect - Seeing The Future
Polygraph examinations have been the leading detection of deception technology used worldwide by leading organizations. Having faced scrutiny over the years and having been continuously refined with research and development, polygraph examinations has stood the test of time as the most accurate and most robust forensic detection of deception tools. Professors Kircher and Hacker, along with cognitive scientists Anne Cook and Dan Woltz might have created a new contender to the throne as the Converus EyeDetect system is taking the world by storm.
In 2002, John C. Kircher and his colleague, Doug Hacker, an educational psychologist with expertise in the psychology of reading, were driving to Seattle to climb Mt. Rainier. En route, they wondered if changes in eye movements and pupil size while reading and answering questions about a crime would reveal deception. They asked themselves, “Would changes in cognitive load affect the eye in such a way that we can capture those changes and be as accurate as the polygraph in predicting whether or not someone is being deceptive?” Thus the idea for an ocular-motor deception test (ODT) was born — later to be branded as EyeDetect. In April 2014, after more than 10 years fine-tuning this technology, these five dedicated scientist were finally able to see their years of work bear fruit when EyeDetect was released to the market.
Since its inception the Converus EyeDetect system had been hailed as one of the most promising lie detection tools since the advent of the polygraph. Its success is largely ascribed to the fact that it is less invasive, easy and quick to implement, more cost effective and yet still boasts significant accuracy ratings. This makes the Converus EyeDetect system an effective and powerful tool for pre-employment and continuous integrity management screenings. The system utilizes an automated algorithm which makes not only makes it easy to implement, but is completely free from external interference or bias. The examinations available are wide ranging and it can be customized to fit the unique needs of the client that wishes to implement it. The questions can also be customized for to different languages. This makes the Converus EyeDetect system perfect for implementation into the South African market.
How Does EyeDetect Work?
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.
While reading a computer-based series of questions, EyeDetect measures an examinee’s response accuracy, response time, pupil diameter, reading behavior and blink rates. The results are consistent with the cognitive workload hypothesis.
- Guilty individuals — when compared to innocent individuals and while responding to simple test statements — make more errors, take longer to respond, make more fixations on the text, have longer reading times, and have longer rereading times.
- Guilty individuals blink significantly less often as they process statements answered deceptively versus answered truthfully.
- Guilty participants show greater increases in pupil diameter for statements answered deceptively than for statements answered truthfully.
- Guilty participants respond faster, make fewer fixations, and spend less time reading and reading statements about the crime they committed than statements about another crime or neutral statements.
Simply put, an increase in the cognitive load is associated with recalling a task and used to distinguish between deceptive and non-¬deceptive responses. This is more pronounced when deceptive individuals respond to complex statements. It takes motivation and effort to deceive.
EyeDetect in the Media
It is no surprise that the Converus EyeDetect system has gained a lot of popularity with media outlets worldwide, and thus far the response has been very positive. As the proud South African supplier of the EyeDetect system we are admittedly nothing less than thoroughly happy. Even better news was the overwhelmingly positive response from international law enforcement agencies.
“The polygraph is ideal for crime-specific incidents. But because of cost, invasiveness, training and upkeep, it can’t be used on a large scale. With EyeDetect, those costs can be reduced significantly. It’s non-invasive, quick, and results are immediate. It helps companies hire and keep honest people.”
