International travelers could find themselves in the near future talking to a lie-detecting kiosk when they're going through customs at an airport or border crossing.

The same technology could be used to provide initial screening of refugees and asylum seekers at busy border crossings.

The U.S. Department of Homeland Security funded research of the virtual border agent technology known as the Automated Virtual Agent for Truth Assessments in Real-Time, or AVATAR, about six years ago and allowed it to be tested it at the U.S.-Mexico border on travelers who volunteered to participate. Since then, Canada and the European Uniontested the robot-like kiosk that uses a virtual agent to ask travelers a series of questions.
