A lie detector kiosk can identify whether flyers are telling the truth through their facial expressions, eye movement, and verbal responses.

A lie detector kiosk designed for Customs and Border Protection in America is a video screen avatar that can detect if travelers are lying through their facial expressions, eye movement, and verbal response.

The ‘Embodied Avatar‘ picks up signs like dilated pupils and delayed responses when it asks a series of questions. If it identifies a potentially deceptive traveler, they can then be sent to a customs officer for further questioning.

The kiosk has an infrared camera to record eye movement and pupil dilation at up to 250 fps, a high-def video camera to capture suspicious movements like fidgeting and scratching, and a microphone to collect vocal data, because lies often feature minor changes in pitch.
