An anonymous reader writes "New Scientist reports on a headband developed at the University of Tokyo that allows the wearer to feel their surroundings at a distance — as if they had cats whiskers. Infrared sensors positioned around the headband vibrate to signal when and where an object is close. There are also a few great videos of people using it to dodge stuff while blindfolded."
A computer lets you make more mistakes faster than any other invention,
with the possible exceptions of handguns and Tequilla.
