The US Department of Homeland Security is developing a system detect your intentions at security checkpoints. Called FAST for Future Attribute Screening Technology, the system examines pupil size, blink rate, direction of gaze, heart rate, respiration rate, skin temperature, and movements of the face, neck and cheeks, all to determine if you have hostile intent. Preliminary tests indicate that the system is about 80% accurate based on tests using 140 volunteers. |
