This Glove Lets Humans Use Their Hands To See Like A Dolphin Underwater
Echolocation plus haptic feedback makes it feel as though you're touching something that you can't even see.
A new glove-like device lets divers explore the murky depths using echolocation, just like a dolphin. The IrukaTact finds objects using a tiny ultrasonic rangefinder, and then uses water pressure on the user's fingers to give haptic feedback. Thus, the diver's sense of touch is extended, even when visibility is so bad that they are swimming blind.
