The University of Bradford in the north of England has developed a new lie detector. While the experiments are only beginning, they have yielded some promising results.

Professor Hassan Ugail, director of the Center for Visual Computing at the university.”We have developed a system by which we can analyze people’s faces for detecting lies in an interview scenario”.

Ugail explained that “when someone is making something up on the spot, brain activity usually changes and you can detect this through the thermal camera”. He said that the areas around the eyes and the cheeks are highly sensitive to temperature rise, while in some cases it’s possible for individual blood vessels to be tracked.

Around 30-40 subjects having been tested so far with a two in three success rate.
