, using their tongue to make clicking sounds and interpreting the echoes that come back, reflected from the surrounding environment.In as few as 10 weeks, researchers have been able to teach participants how to navigate obstacles and recognize the size and orientation of objects using the rebounding calls of their clicks.
Echolocation is a skill we usually associate with animals such as bats and whales, but some blind humansto detect obstacles and their outlines. Some use the tapping of a cane or the snapping of their fingers to make the necessary noise, while others use their mouths to make a clicking sound. psychologist Lore Thaler from Durham University in the UK in June last year when the results were published.Over the course of 20 training sessions, which were about 2 to 3 hours long, researchers found that blind and sighted participants, both old and young, all improved considerably at click-based echolocation.
In the final two sessions, participants had their new navigation skills tested in a virtual maze they'd never tackled before. Even while blinded in this unknown environment, collisions were fewer than they had been at the start of the program.
