Government scientists investigating nonverbal cues to detect terrorists

Scientists at the Homeland Security Advanced Research Project Agency are investigating methods to detect people with malicious intent using nonverbal cues. High resolution cameras, low power laser scanners, and other devices can be used to measure fidgeting, heart rate, pupil dilation, and skin temperature. These sensors could be placed in a security line, record travelers bio signs, and alert the guard if necessary. More information is available in a Los Angeles Times article
