Motion Capture Suit Can Detect Lies by Tracking Your Fidgeting
Engadget has the story on a new, more reliable method of lie detection that reads minute body movements to predict your truthfulness:
Scientists at the University of Cambridge have used full-body motion capture suits to cajole the truth at a much better clip. They put 90 volunteers in $12,000 Xsens mocap suits, and had them lie to other volunteers. By tracking joint displacements, their algorithms could pick three out of four liars — a much more useful result for law enforcement. One researcher said “put simply, guilty people fidget more… independent of cultural background, cognitive load and anxiety.” The team thinks it can fine tune it for even better accuracy, so police may one day be squeezing perps into skin-tight suits rather than finger sensors.
