Now, new 'all-body lie-detecting suit' will make 'lying' all the more difficult

Researchers have recently developed a new form of lie-detector all-body suit test, which performed with the success rate of over 70 percent and could be used around the world within a decade.

Rather than relying on facial tics, talking too much or waving of arms, all seen as tell-tale signs of lying, the new method can help police force monitor full-body motions of people to provide an indicator of signs of guilty feelings, the Guardian reported.

The basic premise is that liars fidget more and so the use of an all-body motion suit, the kind used in films to create computer-generated characters, will pick this up. The suit contains 17 sensors that register movement up to 120 times per second in three dimensions for 23 joints.

The uses of all-body suits are expensive, they cost about 30,000 pounds and can be uncomfortable, and Ross Anderson and his colleagues are now looking at low-cost alternatives. These include using motion-sensing technology from computer games, such as the Kinect devices developed by Microsoft for the Xbox console.
