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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound.
