Using tiny sensors, transmitters and some software, researchers at Sandia National Laboratories have turned personal computers into advanced polygraph machines that they say are capable of monitoring people’s emotions and abilities.

Mentor/PAL uses commercial face-recognition software and off-the-shelf sensors to measure muscle activity, heartbeat, blood oxygen, and breathing depth and rapidity. It provides real-time feedback to improve human performance, particularly in military or other high-risk situations.
