Experiments on the new lie detector being developed by the University of Bradford in the north of England are still at an early stage but have, so far, yielded some promising results.
“We have developed a system by which we can analyze people’s faces for detecting lies in an interview scenario,” said professor Hassan Ugail, director of the Center for Visual Computing at the university.
The thermal imaging camera, Ugail explains, captures variations in facial temperature in response to questioning.
“When someone is making something up on the spot, brain activity usually changes and you can detect this through the thermal camera,” Ugail said.
