Thermal Imaging Lie Detector In Development

Posted by Soulskill on from the he-winked,-get-the-cuffs dept.

beaverdownunder writes with this quote from the BBC: "A sophisticated new camera system can detect lies just by watching our faces as we talk, experts say. The computerized system uses a simple video camera, a high-resolution thermal imaging sensor and a suite of algorithms. ... It successfully discriminates between truth and lies in about two-thirds of cases, said lead researcher Professor Hassan Ugail from Bradford University. ... We give our emotions away in our eye movements, dilated pupils, biting or pressing together our lips, wrinkling our noses, breathing heavily, swallowing, blinking and facial asymmetry. And these are just the visible signs seen by the camera. Even swelling blood vessels around our eyes betray us, and the thermal sensor spots them too."

    All this does is change the rules a bit. All of the things they've listed are things which one could train to do or not do on cue. And even without training if it's only good 2/3 of the time that's not good enough to justify deployment.

    All really good salesmen temporarily believe whatever bullshit they are selling at the time. It's kind of like method acting.
