Border Patrol kiosk detects liars trying to enter U.S.

The U.S. Customs and Border Protection (CBP) is using border crossing stations in Arizona to test new technology to detect liars as they attempt to enter the country; travelers are subjected to a 5-minute interview with the kiosk, while microphones monitor vocal pitch frequency and quality, an infrared camera monitors eye movement and pupil dilation, and a high definition camera monitors facial expression.
