A company named Converus created a new test in which the eye's pupils are recorded as they move, and a computer algorithm determines whether a person is lying or telling the truth. The test marks 90% accuracy, just as the polygraph. Researchers say thes new technology is even better and more accurate.
The EyesDetect technology is becoming more popular because it's easier to operate and more accessible than the Polygraph. Whats more, using the Polygraph can give more unreliable data, because another human is doing the evaluation. Testers can be affected by their emotions, such as sympathy or dislike upon the person being investigated.
EyesDetect is using a really simple technique based on a number of factors, the most important of which is the pupil enlargement in response to a question. As e all know the eye's pupils expand upon telling a lie because lying requires more energy from the body. The brain has a higher load and the pupils expand to gain more light and give the brain more information to process. The changes can be insignificant, sometimes only a fraction of a millimeter.
When undergoing an EyesDetect test, the subject fills out a questionnaire with a series of questions that should be answered only with Yes or No. An infrared camera is recording and tracking the eyes, after half an hour the software compiles a "lie estimate" on a scale from 0 to 100.
Several companies are already using EyeDetect and are implementing the novel technology. It can be very useful in sectors such as criminal investigations, human and social studies, face recognition applications, AI and much more. Imagine in the near future having an app that can tell if someone is lying to you. It may turn out to be true that the eyes are the window to the soul.
Benefits of EyeDetect:
• High accuracy
• Fast (only 30 minutes for a test)
• Nonintrusive
• Cost-effective
• Portable
• Incorruptible and unbiased
