Detecting lies and deception is no easy feat for even the most seasoned agent, but once again technology is helping to solve such problems. Wired takes a look at the Embodied Avatar project, a computer kiosk designed for Customs and Border Protection that’s able to detect liars after asking subjects a series of short questions. The "yes" or "no" answers are judged against feedback from the sensors on board the kiosk: the microphone, for example, picks up subtle variations in speech, while the two cameras help to detect flicking eye movement or dilated pupils. The machine is only being used on a limited basis in Arizona, but the high success rate — 94 percent during one trial in Poland — has the Department of Homeland Security extremely interested in the technology.
