In the University of Bradford in UK, a group of students of Visual Computing are developing an invention to change the way we see faces. This innovation, led by the professor of Visual Computing, Hassan Ugail, and R&D, is going to reveal a new system to detect the facial expressions through a group of cameras and a algorithm. This system in the future can be a useful tool for lie detection.
The system uses two cameras, a HD camera and a thermal camera combined with an algorithm that trails changes in the facial expressions. The research, made by the Psychologist, Paul Ekman, also explains the procedures of the lie, and how the human characteristics change when they are saying a lie. In this case, the researchers found that there are several features, like the positions of the eyes, the temperature of the skin, blushing, etc. that reveal if a person is saying the truth.
This project will be an important improvement for the lying detection, because this is the only system that can detect a lie remotely and without person’s knowledge. Although the previous systems of Polygraph were efficient, they only had 70% of success, but with this new systems, they expect to have a better successful rate by 90% of reliability.
