Echolocation

Natural echolocation is a way of sensing the surroundings by clicking your tongue and interpreting the sound that echoes back. It takes years to learn, so if someone loses a sense later in life it can be difficult to pick up.

Now, the emerging science of Brain Enhancement may have a solution. Professor Kevin Warwick at the University of Reading has developed an ultrasound device that could help blind people echolocate electronically.
