Between night vision, radar, and GPS, who would’ve guessed that the newest innovation in nighttime military navigation would be a belt?The belt in question is loaded with accelerometers and a compass, so it always knows a soldier’s orientation, even if he’s laying down.
Now here’s the killer feature: to help a soldier move silently and accurately in total darkness, the belt will vibrate a sort of Morse code for cardinal directions. When he’s travelling the correct direction, he’ll feel the proper vibration.
Different vibration patterns will even signify “halt” or “move out.”
Such a simple premise that’s been wonderfully applied.
