First off, Darpa wants its biometric device to be able to work from farther away. Right now, it says the accuracy of most systems taps out at around eight meters. And while some see-through devices can see through up to eight inches of concrete, they don't do as well in locations with more or thicker walls. So Darpa's looking for the next system to push that range past 10 meters, particularly in cluttered urban areas.
Finding humans hiding in a particular room is nice, but being able to tell them apart is even better. Like your fingerprints, irises and even your veins, your heartbeat can be a unique biometric calling card to distinguish you in a crowd. Darpa's hoping its sensor can capitalise on this by using electrocardiography -- the analysis of the heart's electrical activity -- to identify and track up to 10 different individuals.
