Human Echolocation
Human echolocation is the ability of humans to detect objects in their environment by sensing echoes from those objects, by actively creating sounds: for example, by tapping their canes, lightly stomping their foot, snapping their fingers, or making clicking noises with their mouths. People trained to orient by echolocation can interpret the sound waves reflected by nearby objects, accurately identifying their location and size. Background The term "echolocation" was coined by zoologist Donald Griffin in 1944; however, reports of blind humans being able to locate silent objects date back to 1749. Human echolocation has been known and formally studied since at least the 1950s. In earlier times, human echolocation was sometimes described as "facial vision" or "obstacle sense," as it was believed that the proximity of nearby objects caused pressure changes on the skin. Only in the 1940s did a series of experiments performed in the Cornell Psychological Laboratory show that sound and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Access For The Blind
World Access for the Blind (WAFTB) is an international non-profit, non-governmental and educational organisation based in California, United States. The organisation was started to strengthen the physical, mental and personal development of people with all forms of blindness, and to increase public awareness about the strengths and capabilities of blind people. It was founded by Daniel Kish of Long Beach, California, in 2000. The primary work of the non-profit is to encourage and teach blind people the technique of echolocation for their movement, so as to minimise their inhibition with respect to people with normal sight. Their innovative training is called FlashSonar, which involves using sound for navigation. Their strategic campaigns are based on the philosophical stand: ''No Limits''. The organisation participated in the medical study of human echolocation in 2011. Vision World Access for the Blind tries to improve the quality of life such as in interaction between blind a ...

White Cane
A white cane is a device used by many people who are blind or visually impaired. A white cane primarily allows its user to scan their surroundings for obstacles or orientation marks, but is also helpful for onlookers in identifying the user as blind or visually impaired and taking appropriate care. The latter is the reason for the cane's white colour, which in many jurisdictions is mandatory. Variants *Long cane: Designed primarily as a mobility tool used to detect objects in the path of a user. Cane length depends upon the height of a user, and traditionally extends from the floor to the user's sternum. It is the most well-known variant, though some organisations favor the use of much longer canes. *Guide cane: A shorter cane, generally extending from the floor to the user's waist, with more limited potential as a mobility device. It is used to scan for kerbs and steps. The guide cane can also be used diagonally across the body for protection, warning the user of obstacles i ...

Flautist
The flute is a family of classical music instrument in the woodwind group. Like all woodwinds, flutes are aerophones, meaning they make sound by vibrating a column of air. However, unlike woodwind instruments with reeds, a flute is a reedless wind instrument that produces its sound from the flow of air across an opening. According to the instrument classification of Hornbostel–Sachs, flutes are categorized as edge-blown aerophones. A musician who plays the flute is called a flautist or flutist. Flutes are the earliest known identifiable musical instruments, as paleolithic examples with hand-bored holes have been found. A number of flutes dating to about 53,000 to 45,000 years ago have been found in the Swabian Jura region of present-day Germany. These flutes demonstrate that a developed musical tradition existed from the earliest period of modern human presence in Europe.. Citation on p. 248. * While the oldest flutes currently known were found in Europe, Asia, too, has a l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Septo-optic Dysplasia
Septo-optic dysplasia (SOD), known also as de Morsier syndrome, is a rare congenital malformation syndrome that features a combination of the underdevelopment of the optic nerve, pituitary gland dysfunction, and absence of the septum pellucidum (a midline part of the brain). Two or more of these features need to be present for a clinical diagnosis — only 30% of patients have all three. French-Swiss doctor Georges de Morsier first recognized the relation of a rudimentary or absent septum pellucidum with hypoplasia of the optic nerves and chiasm in 1956. Signs and symptoms The symptoms of SOD can be divided into those related to optic nerve underdevelopment, pituitary hormone abnormalities, or mid-line brain abnormalities. Symptoms may vary greatly in their severity. Optic nerve underdevelopment About one quarter of people with SOD have significant visual impairment in one or both eyes, as a result of optic nerve underdevelopment. Developmental delays are more common in chi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
