Lie detector uses heat cameras to detect the truth


British scientists have developed a new lie detection test using a heat camera that records the flow of blood around the eyes.

The researchers then combine results with a computer programme which monitors tiny changes in facial expressions

A preliminary study involving 40 volunteers found the system to be 70% accurate in identifying liars.

Nick Higham spoke to scientists behind the test at Bradford University.
