Watching a human navigate like a bat is impressive

Daniel Kish, who lost his eyesight to cancer, is now an expert in echolocation - the technique that a bat uses to navigate at night. This is why he is sometimes known as the real life Batman - although Daredevil would be more accurate. Using these skills Daniel is able to enjoy independence and freedom from many of the constraints that might inhibit him otherwise.

Daniel locates objects in his environment by clicking his tongue and interpreting the echoes that this returns. In fact his sense of visualisation is so strong that he can detect the exact location, size and even density of his surroundings.

Daniel's story has been around for a while but there have been some positive developments - he is now teaching echolocation to other blind people and the results are truly amazing.

Dog with no eyes learns echolocation

Meet blind Rowan the wonder dog - born without eyes - who miraculously finds his way around using ECHOLOCATION. Despite being unable to see, German spitz Rowan barks and listens to the echos to help him tell where he is in relation to nearby objects. Owner Sam Orchard, 41, was shocked when a vet told her that a congenital defect meant Rowan had been born without eyes. But 18-month-old Rowan is now almost indistinguishable from a sighted dog after learning to use his barks to judge where he is.
