He uses echolocation by listening to the reflection of sound waves to navigate in 3D space . He can even ride a bicycle. In addition to being an incredible story of perseverance this is a perfect phenomenon for a unit on waves.

It turned out that the processing of echo sounds activates brain regions that are typically associated with vision rather than hearing . More specifically, echo signals were processed in the visual cortex (rather than in superior colliculus like in bats and other echolocating animals).
How important is echolocation to humans?
“When people echolocate, it’s not like now they can see again. But echolocation does provide information about the space that’s around people, and that would otherwise not be available without vision. It allows them to orient themselves and so on ,” says Lore Thaler, lead author of the paper.
How would Learning How do you use echolocation benefit a person who can see?
Blind humans have been known to use echolocation to “see” their environment, but even sighted people can learn the skill , a new study finds. Study participants learned to echolocate, or glean information about surroundings by bouncing sound waves off surfaces, in a virtual environment.
Is it okay to stare at the sun?
Beware ... damage will occur ! When you stare directly at the sun—or other types of bright light such as a welding torch—ultraviolet light floods your retina, literally burning the exposed tissue. Short-term damage can include sunburn of the cornea—known as solar keratitis.

In conclusion, for some people with severe and permanent visual impairments, and under certain circumstances, regular bicycle and pedelec riding may be possible without noticeable speed reduction or adapted lane position to compensate for their functional impairment .
Can humans learn echolocation?
For years, a small number of people who are blind have used echolocation, by making a clicking sound with their mouths and listening for the reflection of the sound to judge their surroundings.
How do bats see the world?
The bats sense their environments and find prey by calling out and listening for echoes made as those sounds bounce off of objects . This process is called echolocation (Ek-oh-loh-KAY-shun).
Is Daniel Kish real?
Daniel Kish (born 1966 in Montebello, California) is an American expert in human echolocation and the President of World Access for the Blind (WAFTB) , a California-registered nonprofit organization founded by Kish in 2000 to facilitate “the self-directed achievement of people with all forms of blindness” and increase ...
Who was Ben Underwood?
Ben Underwood, 16, passed away at his home in Elk Grove. He lost his eyesight when he was 3 years old, but was able to learn how to make a clicking sound with his mouth and listen to the echoes . His unique ability drew national media attention, including an appearance on “The Oprah Winfrey Show.”
How can I become Batman?
How important is echolocation to the life of animals?
Echolocation is a technique used by bats, dolphins and other animals to determine the location of objects using reflected sound. This allows the animals to move around in pitch darkness, so they can navigate, hunt, identify friends and enemies, and avoid obstacles .
What are some examples of echolocation?
echolocation Add to list Share. Echolocation is what some animals use to locate objects with sound rather than sight. Bats, for example, use echolocation to find food and avoid flying into trees in the dark . Echolocation involves making a sound and determining what objects are nearby based on its echos.
What features help dolphins use and understand echolocation?
Dolphins pick up those echoes with their lower jaw and their enormous foreheads . These areas have cavities filled with fatty tissues that channel the sounds toward the ears and then on to the brain, where they’re interpreted.
