Optimizing Environmental Sounds (02:56)


Daniel Kish has been blind most of his life due to a cancer called retinoblastoma. Unlike most blind people, he has developed his own method of "seeing" via echolocation, a system he calls flash sonar.

Perception Through Sound (03:36)

Up until the 1940s, the way blind people could perceive distance was misunderstood, but American psychologists discovered through experiments that it involved sound. Until Daniel Kish and echolocator Brian Bushway were studied, it was unclear how this was done.

Redefining Visual Cortex (02:37)

Through MRI scans, researchers discerned that the clicks and echoes system used by Kish and Bushway lights up the VI area of the visual cortex. Sound waves entering the ears are similar enough to light waves entering the eyes that the brain can use the waves to create a framework.

Training for Sound Sensitivity (03:45)

Kish works with a young blind student learning to use the echolocation system. Echolocation does not come easily to blind people and is not an automatic result of blindness.

Reawaken and Reactivate (02:58)

Echolocators have trained themselves to use hearing sensitivity to navigate environments via experimentation and hard work but it can be halted by problems.

Reminiscent of Visual Experience (02:46)

Bats use high-frequency echoes which have short wavelengths and produce fine detail. Echolocators produce frameworks closer to a sighted person's peripheral vision, but these frameworks are empty of color and light.

World Access for the Blind (02:17)

Julee-Anne Bell was inspired by media reports about Kish, so she began to learn echolocation at age 38. Four years later, she has opened a nonprofit education center in Australia that is a sister company to Kish's.

High-Tech Bionic Bra (03:09)

Professor Julie Steele and scientists are working to create a bra that is not designed for aesthetic, but that can be comfortably supportive and responsive. Traditional bras offer support by pinning breasts to the chest which is uncomfortable.

Vertical Breast Movement (04:11)

The striking of the heel on the ground causes the breasts to move, and the larger the breasts, the more they move. For support, artificial muscle technology contracts to pull the bra in and increases compression. The technology used in the bionic bra could be used in other clothing fabrics.

Daniel Kish is blind but his ability to “see using sound” is remarkable. His use of echolocation to effortlessly get around using mouth clicks has earned him the nickname “Batman.” Now, researchers are getting a clearer picture on the way his brain turns sounds into images and it’s redefining our understanding of vision. Also, most bras are designed for aesthetics, to look good. Even a sports bra can be uncomfortable at times. But what if a bra could respond when you need more support, and relax when you don’t? A team of Australian scientists has done just that— they are designing a comfortable, high-tech “Bionic Bra” that provides the right amount of breast support, when you need it.
