The Pentagon's Defense Advanced Research Projects Agency has tapped Northrop Grumman to develop binoculars that will tap the subconscious mind. The Cognitive Technology Threat Warning System program, informally called "Luke's Binoculars," combines advanced optics with electro-encephalogram electrodes that can, DARPA believes, be used to alert the wearer to a threat before the conscious mind has processed the information.
I'll believe it when I see it... they promised x-ray vision glasses a long time ago and where are they today? In comic books and 13 year old boy's fantasies, thats where!
They do have cameras that try to determine "threat level" based on facial expressions and actions. At best, they're probably less reliable than a scientology e-meter. I wonder what sort of face you can make to some of these guys that would get you shot.
