This nifty gadget puts a whole new meaning to the way overused saying "the eyes are the windows to one's soul" because it could show a step toward that saying becoming a reality. The Lie Detector Glasses can tell you whether someone is a possible terrorist or has criminal tendencies, and can even show you in real time (!) whether the person you're talking to is lying.

This Israeli technology is still currently being licensed by an American firm mysteriously called "V" so that it can be used even further for law enforcement, anti-terrorism, and other criminal investigations.

How it works: the glasses have internal LED lights which run real time analyses of the wearer's conversations as well as the emotional response of the person the wearer is talking to. The glasses use V's LVA technology, the same one being used to clear people through checkpoints in 30 seconds or less. The lie detector glasses are said to have more than 95% accuracy.

Wisconsin police chief Tom Winscher, who has 25 years of experience with the polygraph and voice analysis technologies, said "The use of this technology in criminal investigations is astounding, not only can you analyze 'live' conversations, but you can do a deep analysis of the interview, or do off-line analysis of recorded conversations. This enables law enforcement to focus on areas that require further investigation, saving a great deal of time."

These glasses could possibly be even better than the polygraph and other psychological testings that are currently being used today because of its time-saving element of providing the wearer with results in real time.
