Dolphins and Children Using Sonar
BBC - June, 2008As part of a scientific experiment, Daniel is unwittingly pitted in a sonar contest against Milo the Dolphin, who subsequently died in captivity. Features Professor Magnus Wahlberg from University of Southern Denmark. Includes a most touching and heart warming segment with one of our blind students - a very engaging and adorably charming 7 year old Samuel, now deceased, who shows us how it's all done. Here are two short edits from this piece on BBC Earth
"Zen" Bats Hit Their Target by Not Aiming at It!
Journal of Science and Technology - February 4, 2010Cynthia Moss and Nachum Ulanovsky
"People without sight use echolocation, in some cases also generating sound by tongue clicking," said Moss. One such person, she noted, is Daniel Kish, ... Totally blind from birth, Kish uses tongue clicking for sonar that allows him to "see" his environment at a very high level, even allowing him to safely ride a bike in a city street. ... "There are no measurements of the directionality of the sound beams used by blind echolocators like Kish," Moss said. "But looking at head movements in echo locating blind individuals, it seems that some may show a similar strategy [to that of fruit bats]."
California Blind Man Uses Echolocation to Navigate Around on His Bike
Inhabitat - Sustainable Design Innovation - March 14, 2011by Ami Cholia
Featuring our work as an innovative example of green transportation. "Kish, who usually takes a stock of the most important structures in a new area before he starts riding, says that the differences in the aural reflections from the buildings around him allow him to tell what angles they're standing at, or whether they have columns or balconies."
